A good time for modernization This year the steel industries in many regions of the world have been facing major challenges. Oversupply and growing pricing pressure have fuelled competition. Steel associations around the world have issued together a global overcapacity warning. Also, the Organisation for Economic Co-operation and Development (OECD) staged a symposium on excess capacity and structural adjustment in the steel sector. China is not only the number 1 steel-producing country, but is also the country with the highest overcapacity these days. Many countries are (again) resorting to protective measures in order to ward off the effects of unfair market practices. In the given situation the steel industries are in transition. Companies change structures and strategies. A number of countries like UK and Italy struggle for the survival of their steel industries. Steel producers have fallen on hard times, no doubt. In order for a company to remain competitive it is crucial to never cease investing. There are some very important key factors for market success: powerful marketing, high quality products and high efficiency production. The latter can be best met with modern production equipment. Actually, in this issue of MPT International, we are presenting several very interesting modernization projects. For example, JSW Steel (India) has restarted its blast furnace No.1 after a complete rebuild with modernization and size increase. The hearth diameter has increased from previously 8 m to 10.4 m, which is one of the largest capacity increases ever seen from a single blast furnace rebuild.

In Italy, the Piombino iron and steel works looks back on a long tradition. However, the blast furnace and steel plants have been idled for years. But very soon liquid steel production will be revitalized with a completely new EAF-based meltshop. The new plant will feature latest technology designed to produce premium steels at high productivity combined with environmentally friendly solutions for low energy consumption and low emissions. This project will enable Aferpi to continue steel and rail production in Piombino using state-of-the-art production equipment. The new steel complex will have all it takes to make world-class long products. In Germany, Saarstahl AG has completed a 30-million-euro investment: a seven-stand continuous blooming mill replacing a reversing rolling stand previously in use for production of wire rod, bar, semi-finished products and forged products in premium qualities. In spite of the current challenging competitive conditions, the company has been adhering to its strategic investments as planned. The new plant offers the possibility of rolling a much broader range of cross-sections, and provides further improved quality and shorter cycle times. With this investment, Saarstahl reinforces its business segment of massive formed parts like crankshafts, drive shafts, wheel hubs, piston pins or other gear components, which are mainly used in plant construction and vehicle manufacturing. Plant modernizations are signals showing that there is no stagnancy or wait-and-see attitude in the steel industry. In the face of adversity, every economy will always need steel.

Initiative for a carbon- dioxidefree steel industry. SSAB, LKAB and Vattenfall are launching an initiative to solve the carbon dioxide problem in the Swedish steel industry. Together, the companies will initiate work to develop a steel production process that emits water rather than carbon dioxide. SSAB’s existing production system is already one of the world’s most efficient in terms of carbon dioxide emissions. Nevertheless, existing steelmaking technology using coke plants and blast furnaces means SSAB is Sweden’s largest single source of carbon dioxide emissions. SSAB, LKAB and Vattenfall together are prepared to assume major responsibility to find a long-term solution to the carbon dioxide problem in the steel industry. With its specialized, innovative steel industry, access to fossil-free electricity and the highest-quality iron ore in Europe, Sweden is uniquely placed for such a project.

Eurofer issues global overcapacity warning. On the sixth European Steel Day, which coincided with the European Steel Association’s 40th anniversary, Eurofer president Geert van Poelvoorde highlighted the European industry’s priority challenges. Van Poelvoorde’s comments came just days after an Organisation for Economic Co-operation and Development (OECD) symposium on excess capacity and structural adjustment in the steel sector that Eurofer attended. This OECD meeting ended inconclusively earlier in the week with a lack of agreement on a global approach to reducing overcapacity. “European steel is globally competitive when faced with a fair market. In the presently distorted market, we call on European policy makers to do more to quickly and effectively defend their strategic steel industry”, emphasized van Poelvoorde. “The situation is very serious,” he concluded.

Status of restructuring of Tata Steel UK. Tata Steel UK has reached an agreement to sell its Clydebridge and Dalzell steel facilities in Scotland. The deal involves the sale of the two plants to the Scottish Government which would then sell them on to Liberty House. The agreement follows Tata Steel’s announcement in October 2015 that it would stop its European plate production, which led to the mothballing of the Dalzell and Clydebridge plants at the end of 2015. Rather than closing the facilities, Tata Steel has continued to maintain them to enable plate production to potentially restart in the future. Tata Steel UK sold its Long Products Europe business to the family investment office, Greybull Capital. As from June, the Long Products Europe business, which in the UK includes the Scunthorpe steelworks, two mills in Teesside, an engineering workshop in Workington, a design consultancy in York, and associated distribution facilities, as well as a rail mill in northern France, is trading under the name of British Steel. Also for Strip Products UK, Tata Steel Europe has been advised to explore all options for portfolio restructuring including the potential divestment, in whole or in parts.

World Steel Association short range outlook 2016 – 2017 worldsteel forecasts that global steel demand will decrease by -0.8% to 1,488 million t in 2016 following a contraction of -3.0% in 2015. In 2017, it is forecast that world steel demand will return to growth of 0.4% and will reach 1,494 million t. According to worldsteel, the global steel industry faces a challenging environment following China’s slowdown. Commenting on the outlook, T. V. Narendran, chairman of the worldsteel economics committee said: “The economic environment facing the steel industry continues to be challenging with China’s slowdown impacting globally across a range of indicators contributing to volatility in financial markets, sluggish growth in global trade and low oil and other commodity prices. The global steel market is suffering from insufficient investment expenditure and continued weakness in the manufacturing sector. In 2016, while we are forecasting another year of contraction in steel demand in China, slow but steady growth in some other key regions including NAFTA and EU is expected. Growth for steel demand in all markets except China is expected in 2017. There are several downside risks to our forecast: the Chinese real estate market and corporate debt problem, anxiety in the financial markets, high (household) debt and volatile capital flows in many emerging economies, geopolitical tensions and unstable political situations in several regions could further worsen the global economic environment. On a positive note, some emerging economies in South and Southeast Asia show resilient growth and along with NAFTA and the EU will support a recovery in 2017. We expect that steel demand outside China will continue to grow by 1.8% in 2016 and this growth will accelerate to 3.0 % in 2017.”

China expected to remain in negative territory While rebalancing progresses, the Chinese economy continues to decelerate. The severe depression in construction activities is contributing to a slowdown in the manufacturing sectors, especially metal products, as
nue. On the positive side, lower oil prices have alleviated inflationary pressure in oil importing countries, giving room for monetary stimulus to boost economic growth and providing opportunities for structural reforms. The commodity markets may be at or near the bottom of this cycle.

Steel demand of the top 10 steel using countries (million t; f: forecast)
well as slower growth in automotive. A recovery for the construction sector is not forecast in the near future. The decline in steel demand in China is expected to be -4.0% in 2016 followed by -3.0% in 2017. This suggests a demand of 626.1 million t steel (15% down from 2013) for 2017, a contraction to 41.9% of world steel use from 47.9% in 2009 and 44.8% in 2015.
Low commodity prices indicative of slow economic growth Falling oil and gas related investments and the squeeze on government spending have affected steel demand in economies relying on oil based reve-
Slowing growth in global trade bites manufacturing growth With the deep integration of China in the global manufacturing supply chain, this sector has slowed as a consequence of weak growth in global trade. Manufacturing exports in emerging economies, in particular in Asia, declined owing to slower Chinese demand. The same is true for developed countries experiencing a reduction in the exports of consumer goods and machinery. Specifically, the mechanical machinery, metal goods and other transport sectors are weakening, but the automotive sector will maintain its growth momentum supported by
INTERNATIONAL INDUSTRY NEWS strong demand in many countries. Outside China the construction sector is expected to maintain its mild, but steady recovery momentum particularly in India, the MENA and ASEAN regions.
Emerging economies exposed to China’s slowdown and ƂPCPEKCN OCTMGV XQNCVKNKVKGU Steel demand in some emerging economies continues to perform below expectation. A worsening external environment in the form of weak exports, low commodity prices, capital outflows and currency devaluation add adversity to these economies. Geopolitical and internal national political tensions are present in many of emerging economies. Brazil and Russia are struggling with their internal and structural issues. Steel demand in both economies is expected to contract strongly in the period ahead. In particular, the Brazilian economy with its political uncertainty has resulted in a severe contraction in steel demand of -16.7% in 2015 and will contribute to a contraction of -8.8% in 2016 with a recovery of only 3.1% in 2017. India’s prospects are brightening due to low oil prices, the reform momentum and policies to increase infrastructure and manufacturing output. India’s steel demand will increase by 5.4% in both 2016 and 2017 reaching 88.3 million t in 2017. In Turkey, steel demand is expected to grow by 3.3% in 2016 and 3.2% in 2017, supported by the government’s focus on progrowth economic policies and low oil prices. Steel demand in the ASEAN 5 (Thailand, Malaysia, Vietnam, Indonesia, Philippines) is also expected to maintain a growth rate of around 6% despite their exposure to China due to their infrastructure building activities and will reach 74.6 million t in 2017. Steel demand in the emerging and developing economies excluding China is forecast to grow by 1.8% and 4.8% in 2016 and 2017 respectively. Steel demand
in these economies will amount to 457.1 million t in 2017, accounting for about 30% of world steel demand.
Developed economies’ recovery momentum maintained despite headwinds While developed economies are also feeling the effect of the worsening global economic environment, they are expected to maintain a stable recovery momentum. Steel demand in the developed economies will grow by 1.7% in 2016 and 1.1% in 2017.

In the EU, a mild recovery in steel demand continues with generally improving economic sentiments and investment conditions. However, uncertainties in the political landscape related to the refugee crisis and Brexit raises risks to the improving economic condition. Steel demand in the EU is forecast to grow by 1.4% in 2016 and a further 1.7% in 2017. In the US, steel demand is dampened by the fall in oil prices and a strong dollar, but an improving job market and a robust housing sector will support steel demand. Steel demand in the US is expected to grow by 3.2% in 2016 and 2.7% in 2017.

Continuous bloom caster and long-product rolling mills started up at Hyundai Steel, Korea The installations are part of Hyundai Steel’s new special steel mill in Dangjin, Korea. The continuous caster is designed for a capacity of 1.1 million metric tons of blooms per year to feed a new combination mill.
Continuous bloom caster at Hyundai Steel in Dangjin, Korea
In October 2015, a continuous bloom casting machine, a large bar rolling mill and a small bar and wire rod mill supplied by Primetals Technologies were started up at the new special steel mill of Korean steelmaker Hyundai Steel in Dangjin. The caster is designed to produce 1.1 million metric tons of blooms per year. It features the 200th application of the monitoring system Mold Expert. The large bar rolling mill produces one million metric tons of end round products as well as billets for the small bar and wire rod mill. The order had been awarded to Primetals Technologies in early 2014. Both caster and large bar rolling mill were started up almost a month ahead of the scheduled date.

Korea and a further one in China. At present, the company is constructing a new plant at the Dangjin site to produce special steels for the automotive industry. In future, bar and wire are to be produced here as primary material for engine and gearbox parts. Annual production of 400,000 metric tons of wire rod and 600,000 metric tons of straight bar and bar-in-coil is planned. The four-strand continuous bloom caster from Primetals Technologies has an annual capacity of 1.1 million metric tons. The caster is equipped with mold-monitoring system Mold Expert. In combination with air mist spray cooling and interior-cooled rollers in the strand guidance system, further technology packages ensure uniformly high quality of the blooms cast. Still hot, these are then fed for direct use in the bar line. This saves energy during reheating and improves operating safety because there is no need for transport of blooms, for example by crane. The large bar mill encompasses a duo reversing breakdown stand and
a finishing train with rolling/sizing stands. The large bar mill also provides billets to be further processed in the small bar and wire rod mill, which Primetals Technologies also supplied. This combination mill has a capacity of 800,000 tons and is designed to roll 160 tons per hour. It includes a continuous roughing and intermediate mill feeding a sizing block supplied by Germany-based Friedrich Kocks GmbH & Co KG for production of bars, a rod outlet with a rod reducing sizing mill (RSM) and also a barin-coil (BIC) outlet. Both the rod and bar-in-coil outlets have slow and fast cooling capability. The small bar and wire rod mill has the highest production rate for a combination mill, and is particularly designed for low-temperature rolling. This improves the metallurgical structure and mechanical properties of end products and enhances flexibility during the rolling operation. Special mechatronics packages and an integrated automation solution ensure the necessary high product quality throughout the plant.

COMPANY PROFILE thanks to the extremely efficient preheating of the charge. The EAF will be charged with a high rate of virgin materials, such as HBI (up to 65%) or pig iron (up to 55%), in addition to scrap in order to reliably meet the required cleanness of the steel produced. The EAF will be designed for a tap-to-tap time of 45 to 59 minutes (in case the charge includes HBI). The steel plant will also comprise a twin ladle furnace and a twin vacuum degasser. These facilities will make it possible to adjust the liquid steel precisely to the required target composition. The steel will then be cast either on the new bloom caster or the new billet caster for SBQ (special bar quality) products. Both casting machines will be equipped with Convex® mould technology and mechanical soft reduction systems. The hot rolling complex will comprise the following production facilities:
▪ new rail and section mill, ▪ existing bar mill, ▪ existing wire rod mill. Whereas billets will continue to be rolled in the existing bar and wire rod mills, the blooms will be processed in the newly built rail and section mill. Hot charging of blooms directly to the rail mill will be possible, allowing great savings of preheating energy and a reduction of gas emission. The new rail and section mill will produce rails with a length of 120 m as well as various beams, sections and sheet piles. At the “hot side” the new rail and section mill will comprise equipment as following: ▪ reheating furnace, ▪ break down mill, ▪ hot saws, ▪ 4-stand tandem reversing mill, ▪ profile gauge with surface defect detection, ▪ rail stamping machine, ▪ rail head hardening line (RailCool®),

Upgrade of the SBQ rolling mill at SeAH Changwon Special Steel, Korea Continuing several decades of successful partnership, Korean specialty steel producer SeAH CSS contracted leading European plant equipment suppliers for a modernization project at their bar and wire rolling mill in Changwon. Commissioning of the revamped equipment is scheduled for the period end of 2016/beginning of 2017. SeAH Changwon Integrated Special Steel Co. (SeAH CSS) is Korea’s only domestic producer of high-grade special steel bar and wire rod. (The former POSCO Specialty Steel and Sammy Steel were acquired by SeAH group in March 2015.) With an annual steelmaking capacity of 1.2 million tons and a steel product output of 1.0 million t, SeAH CSS is among the top ten producers of special steels in the world. Recently, the company started a modernization project at its hot rolling mill. Continuing several decades of successful partnership, SeAH CSS awarded the order for the project to Friedrich Kocks GmbH & Co KG (consortium leader), Morgårdshammar AB and Automazioni Industriali Capitanio (AIC). Two existing Kocks blocks – a precision sizing block (PSB) and a 370/10 three-roll intermediate block – will be replaced by new equipment, namely: ▪ two 2-high HV stands, ▪ three loopers, ▪ one crop & cobble shear and ▪ one 370++ RSB SCS® of the latest design with six stand positions.

ity and economy as well as simplified, safe and environmentally friendly operation. At the core of the future-oriented RSB SCS® is the real-time closed-loop control system SCS® (size control system) acting in combination with 3-roll stands adjustable under load (AUL) and under-load tension control. Operation of the SCS® will be supported by an innovative bar gauge called “4D EAGLE” developed in cooperation with Automation W + R GmbH, Germany. This bar gauge, which is based on the light section principle, provides an extremely high measuring frequency. These features will markedly further improve the rolled tolerances and their reproducibility and, at the same time, simplify operation by means of an automated optimization of the process parameters for the rolled bars and wire rods either by roll gap adjustment or control of the tension between the stands under load. The RSB SCS® will be designed for the production of steel bar and rod in coils with a finished size range from dia.
16.0 to 100.0 mm and any pre-sections for the wire mill with a size range from dia. 5.5 to 16.0 mm at a maximum rolling speed of 15 m/s. The two 2-high horizontal and vertical stands will be supplied by Morgårdshammar. The P600 series stands are well known for their performance in terms of rigidity, stability and size tolerance. Wear resistance of the bearings and other parts is unparalleled. The stands are capable of adjusting the roll gap during rolling, i.e. while the bar is between rolls (also for Nickel alloy grades). This feature allows true closed-loop control within the stands. The stands are fully compatible with the latest electronic intelligent RX guide series and new electronic setting equipment – Smart Eye™. The capabilities of the RX guide include remote adjustment, automatic self-adjustment and self-setting (both in the mill and in the workshop), load and speed feedback. All these features allow for precise inline adjustment during rolling and – without any production stoppages – after a product size
change. Also due to the precise control of the impact force on the rolls, the life span increases up to 170% compared to that of common guide rollers. Automazioni Industriali Capitanio (AIC) will design and manufacture the electrical & automation equipment for both, the new Kocks RSB SCS® and the new Morgårdshammar stands and shear, providing state-of-the-art power control panels as well as a new PLC cabinet and new AC motors. The electrical scope of supply will include two power control switchboards based on Siemens Sinamics S120 motor modules with fully regenerative DC bus supplier (active front end), suited to drive the new Siemens AC motors sized according to the mechanical equipment designed by the consortium partners. AIC will also be in charge of manufacturing an auxiliary AC drives panel, PLC cabinet and control desks. The Italian company’s supply scope further includes the complete engineering for the whole electrical portion as well as PLC software development based on Siemens S7 platform.

New continuous blooming mill at Saarstahl
New blooming mill starts operation at Saarstahl, Germany Saarstahl AG has completed a 30-million-euro investment: a seven-stand continuous blooming mill replacing a reversing rolling stand. Saarstahl group, with its headquarters in Völklingen, Germany, has specialized in the production of wire rod, bar, semi-finished products and forged products in premium qualities. Germany-based Saarstahl AG, which has production locations in Völklingen, Burbach and Neunkirchen, is an important player in the global long products market. In spite of the current challenging competitive conditions, the company has been adhering to its strategic investments as planned. A further milestone has now been completed in the rolling mill at the Völklingen site: There, a 30-million-euro, ultra-modern, continuous blooming line with a rolling train of seven stands has replaced the old blooming stand. Martin Baues, chief technical officer of Saarstahl AG stated: “With this investment we are increasing our manufacturing know-how so as to be able also

in the future to fully comply with our customers’ wishes in terms of quality and flexibility.” The new plant offers the possibility of rolling a much broader range of cross-sections and provides further improved quality and shorter cycle times. After the investment had been approved by the supervisory board of Saarstahl in 2014, construction and engineering work on the rolling train began in April 2015. In order to prevent any production losses, construction was to take place without stopping production. For this purpose, a “construction site bypass” was set up meaning that specially installed turntables and roller tables would guide the billets coming out of the furnace past the construction site to the existing blooming stand. Parallel to this, the foundations for the horizontal and vertical stands of the new rolling train were built and the media cellar and pump room completed. Finally, the mechanical and electrical components – supplied by SMS group – were installed. The total drive power of the new continuous blooming mill is 11,000 kW. Initial tests carried out in January 2016
ran smoothly, and the system was officially put into operation at the beginning of March 2016. The effort of continuing production without restrictions while having a major construction project going on was well worth it. One advantage of the new system is the progress in rolling technology it provides: the greater rolling passes and improved guidance of the billets during rolling provide an additional improvement in the mechanical properties and the surface quality of the finish-rolled steel bars. The higher degree of automation in the control systems leads to considerably shorter cycle times, faster product changes and therefore increased rolling performance. With this investment, Saarstahl reinforces its business segment of massive formed parts like crankshafts, drive shafts, wheel hubs, piston pins or other gear components, which are mainly used in plant construction and vehicle manufacturing. These parts are produced in constantly lighter weights while providing high energy and material efficiency.

Automatic checking and adjusting of roll alignment in tube mills A mobile measuring system installed in tube mills checks the contour and position of the roll passes. Deviations of the alignment can be corrected easily and quickly before they manifest themselves in the tubes produced. Roll chocks, mill stands and contact faces in rolling mills become dirty and worn when permanently in use. This used to present mill operators with an alignment problem, because while the mill stands are checked in a separate calibration stand or on the machine tool in the stand workshop, the mill housings are examined with the aid of a special zeroing stand. This may result in unequal alignments. Until now, the operator was not able to ascertain whether the passes were precisely set until the mill stands were reinstalled

in the mill housing. Only the end product indicated whether everything was correct. For example, if the tube wall thicknesses or outside diameters were non-uniform, it used to be necessary to readjust the settings step by step until the passes were correct. That was a time-consuming and costly procedure. During the past two years, SMS group developed a solution to that problem, the CaliView® system which measures – inline in the mill housing – the roll contours for each pass. The rolls can be checked quickly and easily at any time. This makes it possible for the tube mill operators to directly readjust the roll pass. With CaliView®, it is thus possible to detect any incorrect settings beforehand and not only after they have become noticeable in the finished tube. The system uses an optical process to measure the roll passes in PQF®, MPM
or SRM/stretch-reducing mills. Most recently the system has also been in use in cross-roll piercing mills and in stand toolshops. CaliView® measures the positions of the rolls in longitudinal rolling mills directly after each roll change, providing the necessary data for the rolls to be optimally set right away, without any loss of time. This is the only measuring system that in cross-roll piercing mills reliably indicates whether the rolls and guiding elements are correctly positioned in relation to the mandrel. In longitudinal rolling mills, CaliView® measures the contours of the rolls of a pass in a non-contact manner, two-dimensionally in a plane surface, right-angled to the rolling direction and through the point of the groove root. In cross-roll piercing mills, it measures the highest point of the rolls.

Backlight Camera

Arrangement of the system in a PQF® rolling mill
Portable measuring solution The mobile system comprises a light source, a camera, a mobile control unit and the computer for the configuration of measurement parameters and evaluation of the measurement results. The light source and the camera have been developed specially for SMS and designed specifically for the conditions in a tube mill. The light source backlights the passes individually in the mill, enabling a shadow image of each pass to be obtained. This shadow image of the LED light is captured by a digital camera, which transmits the data on to a control device. The camera can be positioned at either the entry or the exit side of the rolling mill. During the measurement, the control unit receives the data from the camera via WiFi or LAN and prepares them for display. The control unit has an operating duration of at least four hours and, with a WiFi connection, a range of up to 100 metres. Thus during the measurement the results can also be directly viewed in the control pulpit of the rolling mill and utilized for pass correction. The parameters required for the measurement, such as the distances between the mill stands to be measured, references for pixel factor and the defined passline, or design data for the roll contour, are entered into the configuration computer beforehand and only once per rolling mill. The spatial orientation of the rolls, for two-, three- or four-roll systems, can be selected by the operator via a drop-down menu in the CaliView® software. The rolling mills to be measured are cre-
ated in the configuration and evaluation software. First the passline and then the rolling mill, followed by the setting plan, must be entered into the menu. Finally, the pass data is entered. The contour of the rolls can be defined by means of various input masks and be directly viewed. A configuration contains all the significant data of the respective rolling mill, for example, the quantity of measuring positions, number of rolls per stand and the pass diameters. For measurement purposes, the control unit and the camera constitute one unit and are connected via a WiFi or LAN interface. All of the camera functions are guided and visualized via the control unit. The control unit receives the configuration of the rolling mill from the configuration software. Besides the possibility to adapt the configuration data, the software offers the option to view the measurement results during the measurement in the same format as in the evaluation software. Deviations in the pass, from the passline and from the diameter are displayed while the measurement is going on. Overlays for evaluation ranges, contour recognition and inscriptions can be switched as required
for a better overview. In order to document changes made to the rolling mill, several measurements can be taken following a once-only definition of the references.

Deviations in the pass and from the FGƂPGF RCUUNKPG
Most helpful interpretation of measured data Plant operators may perform optical gauging of passes with diameters from 20 to 577 mm. For diameters smaller than 250 mm, the precision is +/- 0.1 mm, for diameters from 250 mm upwards, it is +/- 0.2 mm. The system performs several measurements directly after one another, in parallel or at certain intervals, and in different configurations. Following a measurement, CaliView® analyzes the pass design and calculates any incorrect settings. On the basis of this analysis, the mill operator can immediately reset the pass in order to optimize the product quality. For each pass, the system requires a maximum of 30 seconds to record and evaluate the data. Thanks to the specially programmed pass analysis software, it does not make a difference whether two, three or four rolls per stand are used and how the stands are arranged in the mill. CaliView® evaluates the symmetry of the two, three or four rolls. Any deviations from the ideal positions are displayed by the system in numerical and graphical form, both on the control unit during the measurement and on the configuration computer after the measurement has been completed. MPT International 3 / 2016
The system indicates the radial and axial roll offset against the mill stand and the passline. This allows the operating personnel to initiate corrections exactly where needed. In the past, mill operators had often felt the need of such a system. CaliView® can be retrofitted to existing pipe and tube mills. In practical application, the system has provided convincing results: It reliably measures any incorrect pass alignments and helps to minimize them, for example by means of roll position corrections – both between the stands and in the stand itself. The measurement results are stored in a database. This enables tube makers to build a comprehensive production history and compile statistics on the causes of defects. For example, CaliView® also localizes any incorrect settings of mill stands and passes during day-to-day operation caused by grease layers of varying thickness between the coupling surfaces between the mill housing and the mill stand, by contamination of the V-guides or as a result of the manufacturing and assembly tolerances of the stand components. The mill operators have constant knowledge of the degree of roll wear. For tube and pipe producers this means that they are not only able to set and check the roll passes but also
monitor the effects of repairs on the pass positions.
Conclusions SMS group has developed a mobile measuring system that, installed in tube rolling mills, checks the contour and position of passes. CaliView® monitors the alignment of the passes without any elaborate manual measurements. Deviations detected by the system can be easily and quickly corrected before they manifest themselves in the produced tube. CaliView® enables rolls of a pass to be optimally set to one another and in relation to the passline. In PQF® and MPM mills (premium quality finishing lines and multistand pipe mills), it is also possible to recalibrate the hydraulic capsules and the mechanical screwdown systems in an inline procedure. The system is also capable of checking the rolls in extracting mills and in sizing and stretch reducing mills. With CaliView® is it possible to directly align the rolls in longitudinal rolling mills after each roll change. The inline measuring system can meanwhile also be used in cross-roll piercing mills and in stand toolshops. In cross-roll piercing mills, CaliView® reliably indicates whether the rolls are correctly positioned in relation to the mandrel.

Lubrication in an integrated steel plant requires a wide range of utilities and can therefore be a major challenge. All steel plant sections such as ironmaking, steelmaking, rolling and finishing as well as auxiliary units, have various
equipment and operating conditions; extreme loads, low and high speeds, severe temperature changes and dusty, humid – often acidic – environments. The equipment used in the raw material blending, blending yard, beneficial
SPECIAL EQUIPMENT plant, sinter plant, in the coke ovens, and blast furnaces of the ironmaking section works under high temperatures, and in a dusty and corrosive environment. Although crushing and screening equipment operates at slower speeds than the other operations here, they are still subjected to heavy shock loads. The steelmaking area includes blast furnaces, continuous casters, and a lime plant. In addition to the typical operating conditions in the ironmaking process, water ingress needs to be factored in. The rolling and finishing processes are done in hot strip mills, cold rolling mills, primary boom bar mills, bar and wire rod mills and in merchant mills. In these areas, heavy shock loads, water and scale ingress, high temperatures and higher speeds are the dominating operating conditions. Lastly, the auxiliary units in an integrated mill, such as a deslagging device, scrap disposal device, ladle demolition stand, and maintenance stands for ladles, are found in all the major areas, and can be subjected to the various operating conditions previously mentioned. The variety of lubricants commonly needed to cover these areas all consist of mineral and/or synthetic base oils. These lubricants are considered flammable.

fire-resistant hydraulic fluids into a lubricating grease. This new fire-resistant grease line is marketed under the brand name QUINTOPLEX™.
*QY VJG Ć‚TG TGUKUVCPV ITGCUG (KTG TGUKUVCPV J[FTCWNKE ĆƒWKFU works QUINTOPLEX™ fire-resistant grease formulated as a lubricating has a very low vapor pressure, which grease Approximately three quarters of the lubricating grease in an integrated steel plant are used in the continuous caster and the hot mill. An important function of the grease, in addition to lubrication, is to protect the bearings by forming a grease collar, sealing them against water and dust ingress. The formation of the collar is ensured by regular re-lubrication via a centralized lubrication system. If the grease collar is not stable enough (e.g. poor water resistance) or the re-lubrication volume is too high, the risk of fire is increased as grease can drop onto a flammable surface or sparks can fall onto accumulated grease and ignite it. Fire-resistant hydraulic fluids are already used to reduce the risk of fire in steel mills, but it is a new initiative to use a fire-resistant grease as a preventative measure. Quaker Chemical Corporation (“Quakerâ€?) has now successfully transferred the proprietary technology of the base fluids used to formulate

means it removes fuel, one of the ele-
ments needed to start a fire based on the “fire tetrahedronâ€? (see box “Fires – facts and ways to put it outâ€?). By removing the fuel element, the risk of a fire starting is reduced. Grease suppliers may use different terms to describe a grease that stops the perpetuation of fire. Commonly used terms are: â–Ş Fire-resistant / flame-retardant: The grease is difficult to ignite and burns
For a fire to start and evolve, it must have four elements present: heat – fuel – oxygen – uninhibited chain reaction
Once a fire has started, it can spread in three different ways: by conduction, by convection, by radiation.
Once the fire has spread, there are four ways to put it out: cool the burning material, exclude oxygen, (CEVU CDQWV Ć‚TG CPF ways to put it out

only at very high temperatures and needs an additional energy source to keep burning. ▪ Non-inflammable: The grease does not burn under normal conditions; non-inflammable greases are only those based on perfluor-compounds. All other products can and will burn when heated up to a certain temperature. ▪ Self-extinguishing: The grease starts to burn, but doesn’t continue to do so for several reasons. It does not produce enough energy to keep the temperature at a burning point, and the reduced fuel means as low volatility as possible, with the removal of oxygen and the production of inert gases such as carbon dioxide. ▪ Heat-resistant: This indicates whether a grease can withstand oxidation (ageing); not every fire-resistant grease is also heat resistant and vice-versa. There is no standardized test available to determine the fire-resistance of a grease. However, to demonstrate the level of QUINTOPLEX™ fire-resistant grease, Quaker Chemical uses two inhouse tests as following: #1. A torch flame is held to the grease to see if it will ignite. #2. The grease is placed on a hot ceramic disc at a temperature of 815°C. Such tests not only show how QUINTOPLEX™ behaves, but can also be used

to compare to other grease types, including mineral oil based. In addition to being fire-resistant, QUINTOPLEX™ grease offers a number of benefits that also make it an option for any application in a steel plant; it has a wide operating temperature range, various viscosity grades are available. It can be used with and without solid lubricants.
#P CRRTQCEJ VQ ƂTG UCHGV[ In the hot rolling mill of a major North American steel producer, hot scale was falling off the 1,260°C temperature steel bars as they exited the walking beam furnaces, causing excess grease on the bearings to catch on fire. The steel producer thereupon instructed Quaker Chemical to develop a fire-resistant grease that could be
used on the roller bearings to reduce the amount of fire hazards. Quaker Chemical proposed QUINTOPLEX™ LXS 1002-EP grease for use on the hot rolling mill. Before introducing QUINTOPLEX™ into operation, the steel producer challenged the fire-resistant properties of the grease with tests that exposed it to open flames and extremely hot metals. QUINTOPLEX™ passed all the tests performed, resulting in its introduction into the hot rolling mill lubrication system. Running their system with the fire resistant grease, the mill realized 90 percent less fire hazards. Furthermore, the continuous water supply the mill was using to control the fire hazards could be removed, which led to a reduction in corrosion on the roller bearings.
Keeping operations running smoothly Mill operators should work with a grease supplier who has the expertise to offer technical advice to help evaluate situations, and who can offer realistic solutions to solve problems ranging from production efficiency to worker safety. At a minimum, grease manufacturers need to provide sustainable product solutions that require less volume and reduce energy during use, in order to bring real value to the customer.

The facilities, which began operations in February 2016, consist of ▪ a bar drawing line, ▪ two grinding machines and ▪ a bar inspection system. State-of-the-art technologies guarantee consistent quality that is reproducible at any time for a total bar length between 2 and 6.2 m and diameters of 5 to 16 mm. Most of the bright steel bars made in Hagen are used in the automotive industry and in engineering applications. Clients of Deutsche Edelstahlwerke use the bar to manufacture, for example, high-quality valves that are built into highly efficient car engines. In keeping with the automotive industry’s efforts to reduce the overall weight of the automobile, Deutsche Edelstahlwerke sees great potential for valve steel in the future since not only more, but above all thinner valves are needed to reduce vehicle weight sustainably. The technical customer support team of Deutsche
Edelstahlwerke can find the right special steel solution for the specific application in cooperation with the sub-suppliers and car manufacturers. With the new bar drawing line, the semi-finished product is manufactured as efficiently as possible in terms of time and still fully meets the customers’ high quality requirements. This allows to improve delivery performance and make another contribution to process reliability and material efficiency at the customers’ facilities.
High-productive chain track drawing machine Quality and process reliability along the entire supply chain is the declared objective of Deutsche Edelstahlwerke. To meet this goal, an innovative approach was taken in the design of the new bar drawing line, specifically with respect to the selection of the right drawing tech-
SPECIAL EQUIPMENT nology. Whereas in the past conventional cam-driven drawing machines were used, Deutsche Edelstahlwerke is now using a Danieli chain track drawing machine. “With the chain track drawing system we achieve a drawing force of up to 7 t and, with up to 100 m/min, a much higher drawing speed than with the previous process. At the same time, this chain track drawing technology allows us to produce uniformly thinner and top-quality bar despite these high speeds. And we still achieve greater process reliability,â€? explains Thomas MĂśller, technical manager at the Hagen site. Deutsche Edelstahlwerke generally uses 5.5 to 30 mm diameter wire rod made of stainless steel, tool steel or engineering steel. “We use high-alloy stainless steel grades for over 50% of our bars, including the valve steel for the automotive industry. One example is PyrodurÂŽ 4718, our most popular steel for intake valves in the dimensional range between 4.8 and 24.0 mm diameter. The steel’s surface hardness of over 60 HRC in the finished valve is extremely impressive,â€? says Thomas MĂśller. “We are the first steel producer in Europe to use a chain drawing line to produce high-alloyed stainless steel bar. And it has been obvious since the plant started operations that we made the right decision. Before investing, our specialists ran extensive pilot tests and held technical discussions whether the use of the chain track drawing technology would actually be appropriate for the intended use and have additional positive effects. Our test runs and the products manufactured since operations began have definitely confirmed their studies.â€?
/QTG ĆƒGZKDKNKV[ CPF RTQFWEV URGEKĆ‚E SWCNKV[ CUUWTCPEG Yet only assured quality is top quality. This was the motivation behind Deutsche Edelstahlwerke’s decision to complete the investment in the drawing line and the two new grinding machines with single-bar feeding with a state-of-the-art crack detection system. Based on eddy current testing, the system detects surface flaws in a most reliable manner, has a bar separator and was designed specifically to test thin bar. Drawing, straightening, grinding, testing – not only the plants and machines are new but also the plant layout. Time-consuming transports between

the bar drawing line and the machining and testing machines have been eliminated and transport has become more efficient and economical. Moreover, Deutsche Edelstahlwerke has designed the manufacturing areas in the production hall in such a way that also material not coming from the bar drawing line can at any time be ground, inspected and tested. This makes the company more flexible when processing customer orders and makes process sequences faster and smoother. “Today, in-process inspection and testing of the material are possible at every stage of production along the entire bright steel line,â€? says Thomas MĂśller.
The new line operates with a drawing force of up to 7 t and, with up to 100 m/min, a much higher drawing speed than before

The project will ensure the company’s future position within a highly competitive market environment. It proves Outokumpu’s response to the increasingly high quality demands set by its industrial customers. The German plants of Outukumpu are an integral part of the group’s global supply network, and Outokumpu is perfectly positioned in one of the most important European markets for stainless steel.

fies about half of the German demand for stainless steel from its four plants and three service centres. After Outokumpu took over the stainless steel business from Thyssenkrupp a few years ago, two stainless steel meltshops – at the Krefeld and Bochum sites – were closed down. However, Outokumpu decided to considerably modernize the Krefeld site. Today the plant is home of the German headquarters of Outokumpu Nirosta GmbH as well
as a state-of-the-art cold-rolling facility. Ferritic and martensitic stainless steel strip products are manufactured here to thicknesses of 0.2 to to 6 mm, up to 1,530 mm wide. On a total area of around 200,000 square metres, Outokumpu Nirosta in Krefeld produces high-quality stainless steel grades with unparalleled surface quality for applications such as home appliances, pots, cutlery, general tubing and sheet and tubing for automotive exhaust systems.
COLD ROLLING Enormous investment programme for the Krefeld site The “NiFOâ€? project – Nirosta Ferrite Optimization – is the centrepiece of the restructuring and modernization of Outokumpu Nirosta in Germany. The company initiated a 108-million-euro investment programme to optimize production of ferritic cold rolled strip at the Krefeld site. The aim is to expand the cold rolling capacities at the Krefeld plant to take over production from another production site close by in DĂźsseldorf-Benrath that is closing down. For that to happen, Outokumpu has built four major plants at the Krefeld site as following: â–Ş a batch-annealing plant, â–Ş another continuous bright-annealing line, â–Ş another continuous pickling line, â–Ş another cold rolling mill. While the batch-annealing facilities are installed in a completely new building, the other strip processing lines were installed in existing factory halls. The dismantling of previous (old) machines began back in December 2014. And, following extensive construction work, new equipment has been assembled in Krefeld. On 26 January 2016 Outokumpu held the official roofing ceremony for the new building of the batch-annealing plant. On 1 April 2016 the first coil was annealed just 10 months after groundbreaking. These dates marked important milestones in the investment programme that enhances the production capabilities of ferritic materials with new facilities for batch-annealing, pickling, cold rolling, bright-annealing and temper rolling processes. The investment initiated two years ago strengthens the company’s long-term competitiveness in one of its most important markets. “It is Outokumpu’s biggest ongoing investment,â€? says Oliver Picht, senior vice president for Outokumpu’s business line Nirosta. “This modernization will ensure we continue to meet the highest demands of our customers for top-quality stainless steel.â€? Commissioning of the new equipment is scheduled for completion in July 2016. The expanded production of ferritic materials will then encompass the whole process chain for high-quality stainless steel strip with
high-gloss surfaces. With the state-ofthe-art process and equipment technology, Outokumpu is able to reduce energy consumption and emissions in the production of stainless-steel products. Ferrite manufacturing is closely linked to the research and development (R&D) department in Krefeld.

The over 26-metre-high building (86 m long, 34 m wide) is the most visible alteration to the Krefeld site. Following the roofing ceremony in January, installation of the batch-annealing equipment has been going on, with production ramp-up planned for mid-2016. Equipment and components have been transferred from the DĂźsseldorf-Benrath site. The new bell-type annealing facility comprises 21 bases. The whole project is being carried

Around 2,500 cubic metres of concrete were used for the complex underwater construction work. Approximately 30,000 man hours went into installing the equipment. International technology group Andritz was awarded the order to supply the whole continuous pickling line. The scope of supply included the laser welding machine, the automation and electrical equipment, as well as the instrumentation systems. One special feature of the facility is a scale breaker which can stretch the strip by up to 6%. The pickling line is designed for processing ferritic and martensitic stainless steel strip with gauges from 1.5 to 8.0 mm and tensile strength between 300 and 800 MPa. At the exit section an intermediate paper layer is inserted into the coils, which have a maximum outer diameter of 2,100 mm and weigh up to 25 t. Strip speed in the pickling section is 14 to 24 m/min, while the strip speed in the entry and exit section may attain 22 to 36 m/min. According to the project schedule, commissioning of the pickling line will have started in June 2016.
Revamped cold rolling and ƂPKUJKPI RNCPVU Already in 2014, Outokumpu awarded to SMS group the order to revamp the cold rolling mill “SG3” of type MB 21BB-61“, with the aim of technically updating the cold rolling stand previously modernized in 1991. The “SG3” 20-roll cold mill designed for a maximum strip width of 1,570 mm and strip gauges of max. 10 mm and min. 0.5 mm will continue to be used for the production of high-grade special-steel strips made of austenitic, ferritic and martensitic materials. The range of products includes, in particular, thingauge ferritic strips in high-gloss quality (2R bright-annealed). The cold rolling mill was modified in order to be able to manufacture mirror-finish material. The existing squeezer system was converted to a dual-cassette wiper system, including a changing device and designed to operate with different types of coated wiper rolls. One of the aims of the
conversion work was to roll the entire thickness range at maximum rolling speed. Commissioning of the modernized mill took place already in 2015. SMS group was also awarded the order for the revamp of the existing rolling-oil treatment plant. Key equipment included a new dirty-oil tank with automatic pre-separation and the ultra-fine filter system Supafine® developed by SMS.

New colour coating and printing line at Lysva, Russia Hot commissioning of the new colour coating and printing line for the production of varnished, painted and printed strip was started at the Lysva Metallurgical Plant in February 2016. Located in the Perm region of Russia, Lysva Metallurgical Plant (LMZ) is one of the oldest production plants in the Urals, founded in 1785 by the family of prince Boris Grigorievich Shuhovskoi. Today, LMZ is Russia’s only producer of electrolytically galvanized and colour-coated strip products. Ten years ago LMZ began to modernize the production facilities and develop new technological processes, which expanded the product line and improved the quality of products. In 2013, the first stage of a large-scale modernization project commenced. During that first stage, a new colour coating line with printing technology and a capacity of up to 110,000 t/year was to be installed. In February 2014 the contract for the supply of the new strip processing line was signed with Danieli. Construction was completed in late 2015.
Technical milestones of the project The colour coating and printing line was designed to produce 110,000 t/year of thin strip from 0.3 to 1.5 mm thickness, in widths up to 1,500 mm. Since the line had to be installed in the existing building at LMZ, a customized layout and compact design were needed so that the entire line would fit into the available space of 160 m length. The line has three coaters (prime, finish and clear) and one printing section with three printing heads. Convection ovens, supplied by Danieli Centro Combustion, are located after each coater; here the paint coats are cured by hot air. The first coater (prime coater) applies the primer on both sides of the

strip, while the second one (finish coater) applies the top finish coat and the backing coat. If printed products are required, the first coater applies the primer on both sides of the strip, while the second coater applies only a top coat called “base coatingâ€?. After the curing oven for the base coating, there is a printing section with three printing heads, which apply the ink to the painted strip using pattern rolls. After each printing section a hot air dryer dries the ink applied to the strip surface. After the printing section, the third coater (clear coater) applies a transparent or “clearâ€? paint to the strip surface as a protection and to enhance its resistance to corrosion. In order to purify the solvent-containing air coming from the ovens and coating rooms, two purification systems have been installed. A rotoconcentrator has been arranged downstream the coating rooms. This is an auto-regenerative zeolitic wheel which reduces the solvent concentration from 100 mg/ mÂł down to 20 mg/mÂł (s.t.p.). The wheel
directly adsorbs the solvents, which are regenerated with a hot air flow. A regenerative thermal oxidizer (RTO) has been installed downstream the ovens in order to oxidize the solvents. The concentrated flow coming from the wheel is also sent to the RTO. Oxidation reduces the solvent concentration from 8 g/m³ to 20 mg/m³ (s.t.p.). During normal operation, oxidation is performed without gas consumption. The entire electrical and automation systems, including motors, drives, MCS, level 1 and level 2 process controls, were designed and supplied by Danieli Automation. Coating layer thickness control, accurate strip temperature control and efficient drive systems are the key technological components of Danieli Automation’s 3Q technology package. To ensure smooth and fast ramp-up, supervision of installation, start-up and commissioning is also provided by Danieli. Hot commissioning has already begun.

The centrepiece of each thermal power plant from DeVeTec: the ORC steam expansion engine
Excess process heat is generated during many steps in the energy-intensive production and processing of steel. Two heat power plants of German-based engineering company DeVeTec demonstrate that huge amounts of this energy can be efficiently recovered. One plant is part of a comprehensive energy efficiency scheme of German cold-rolled steel manufacturer Bilstein. In a fundamentally new approach, any excess energy from the coils, heated to up to 700°C, is extracted during the cooling and made available to other consumers in the plant as electricity or thermal energy. This plant is an example of high efficiency with a widely fluctuating heat supply: Once the cooling process starts, the hydrogen used as inert gas is cooled down from 700 to 350°C. The energy extracted then heats thermal oil up to 270°C in a special bypass cooler. This oil is used to evaporate the ethanol that the Organic Rankine Cycle (ORC) module uses to generate electricity with its steam expansion engine. The heat derived from the condensation of ethanol is used for hall heating and for heating up an emulsion bath. For every annealing heating cycle, the ORC plant generates about 350 kWh of electric power which don´t have to be purchased from external providers. The waste heat power plant has been part of the annealing line at Bilstein since 2014. As an industrial-scale pilot project that helps to improve resource efficiency it was funded by the German Federal Ministry of Environment as part of its Environmental Innovation Programme. The other waste heat power plant of DeVeTec has been in operation on the plant grounds of the Badische Stahlwerke in Southern Germany since the beginning of 2014. Badische Stahlwerke uses waste heat from a natural

gas-fired pusher furnace to generate electricity. Due to limited space, the waste heat power plant was erected at a height of 8 m and distance of 80 m to the ORC heat exchanger. Badische Stahlwerke now plans to take the waste heat from the ORC process to operate an absorption chiller. By using an induced draft blower in the flue gas line of the ORC heat exchanger, the influence of the waste heat power plant on the existing pressure regulation of the pusher furnace could be ruled out.
Ecological and economic DGPGƂVU DeVeTec’s waste heat power plants recover the maximum amount of energy from industrial processes by simultaneously generating electricity and using the remaining energy at different temperature levels. They are also a model example of CO2-neutral and zero emission power generation because a DeVeTec waste heat power plant with a nominal output of 200 kWel can save up to 3,000 t/CO2 per year. Industrial users confirm that DeVeTec’s plants pay for themselves in less than four to five years, and even
in less than three years, depending on the configuration, while they simultaneously generate electricity and utilize heat. Using waste heat generation power plants reduces the costs of externally procured fuels and electrical energy. To German companies also applies that, depending on the case, this self-produced electricity is partly or sometimes even completely free from levies or other charges of the Renewable Energy Law. Here, operators can raise additional revenue with the CHP (combined heat and power) bonus, because DeVeTec’s waste heat power plants are CHP plants in compliance with Germany’s Combined Heat and Power Act. Since these operate automatically and do not require on-site monitoring, no costs are incurred for personnel.

ate power. Instead of water, an organic fluid (bioethanol) is used here, which exhibits efficient thermodynamic behaviour even at low temperatures. Waste heat flows can be exploited efficiently and economically starting at 230°C. However, when you take a look at industrial waste heat, the heat engine must depend on the generated heat such as from the production process for example. This is what the piston expansion engine was developed for. It is the basis of the DeVeTec waste heat power plant. Here, it can respond very quickly to changing waste heat condi-
constant efficiency. Should other heat sources with lower temperatures be exploited, then the same engine can also be operated with other organic fluids without having to be modified. The engines also provide heat to other users at a temperature level of about 80°C. More than 90% overall efficiency can thus be achieved. The recovered energy can be used to heat plants, dry material or temper processes for example. The waste heat power plants are suitable for all processes where temperatures exceed 230°C. More recently, fluids that already achieve significant efficiency at 170°C are also available.
door plants. Bioethanol is also distinguished by its low price. Right from the beginning of the development, DeVeTec designed the plants in cooperation with German TÜV (Technischer Überwachungsverein/Technical Supervisory Association) in order to avoid any potential hazard. Special emphasis was drawn to the subject of fire and explosion protection.

tions and thus exploit an exceptionally high proportion of the valuable waste heat. The piston expansion engine itself is highly efficient; these engines achieve a very high pressure differential in a single stage so that the enthalpy gradient increases significantly to thus generate much more electricity than is possible using related technologies. This high pressure differential results in high temperature differences (> 150°C) and a large enthalpy difference and thus in a high energy yield. Waste heat power plants by DeVeTec generate electricity efficiently even under partial load conditions. Depending on the amount of waste heat available, one can choose between three versions of the steam expansion engine: the V8 engine operates in the 0 – 130 kW range, the V12 engine in the 0 – 200 kW range, and the V16 engine in the 0 – 266 kW range at nearly MPT International 3 / 2016
'NGEVTKEKV[ HTQO RTGXKQWUN[ WPWUGF YCUVG JGCV DeVeTec’s machines use a method known as organic rankine cycle (ORC). The method is a traditional steam cycle: the waste heat flow of a process is used to vaporize an organic medium – in this case ethanol – which is then expanded in a steam expansion engine. The depressurized vapour is fed into a condenser to be liquefied there. The liquid ethanol is then fed back to the evaporator with a pump and evaporated again. The process is thus complete and the cycle starts all over again. Normally, the organic fluid used by DeVeTec is bioethanol, which has proven itself due to its many advantages. For example, it is not toxic and therefore relatively environmentally friendly. Moreover, it does not freeze – an important argument for out-
plication partners over five years, DeVeTec’s waste heat power plants are now available in a single product family with three performance classes. This allows unused waste heat flows between 800 kW and 2 MW to efficiently generate electricity at a temperature level above 230°C. It is possible to retrofit the waste heat power plants as DeVeTec delivers them as mobile container units together with the expander generator unit, the pump unit and the control unit. The entire heat transfer technology can also be implemented. If higher outputs are required, multiple plants can be connected in parallel. The plants work fully automatically and are monitored remotely. The specially developed noise & vibration guard monitors signs of wear, protects the engine from potential damage and, in the context of preventive maintenance, minimizes the risk of faults.

Hot metal and liquid steel are desulphurized by injection of one or multiple agents (CaC2, CaSi and/or CaO) with a gasevolving carbonaceous additive at a defined injection rate. Hot metal desulphurization serves to relieve downstream metallurgical processes from desulphurization work. For example for CSN (Companhia Siderúrgica Nacional), Stein Injection Technology supplied two new units for the injection of lime into two torpedo cars. At a rate of 14,000 t of hot metal per day, a sulphur content reduction in the hot metal from 0.050% down to 0.005% has been achieved. Further, calcium carbide use has been reduced by 60%. Hot metal desulphurization in a ladle upstream of the BOF and downstream ladle metallurgy of steel are generally applied to achieve the required steel grades. In EAF steelmaking, desulphurization of steel takes place in the ladle or the ladle furnace. CaC2, CaSi and CaO are most commonly used to desulphurize steel in combination with immersion lances and a stirring method. In hot metal desulphurization, magnesium is additionally added in powdered form with a carrier gas via an immersed lance. The smart combination of products, equipment and ser-

In complex plants, the vibration behaviour may be influenced by factors associated with the process. Therefore damage to machine parts can only be detected in a reliable way by simultaneously monitoring all machine, process, material and quality data. To meet these requirements, Iba AG has refined its well-established ibaInSpectra product range. With ibaInSpectra, mechanical vibrations can be monitored in a time-synchronous and continuous way. Frequency analyses can be displayed in real time. This way, critical machine conditions or exceeded limit values can be signalled. As the ibaInSpectra technology module is integrated into the ibaPDA process data acquisition system, also other relevant data from the plant can be acquired. Thus, the user can identify relations between the vibration effects and the process behaviour. As refined solutions, Iba now offers ibaCMC and ibaCMU-S for long-term analysis of the machine status. Built in a modular structure, it consists of up to four digital and four analogue input and output modules and vibration inputs according to the IEPE standard.

'NS CHO F@KU@MHYHMF KHMD QDU@LODC VHSG MDV @HQ JMHED RXRSDL STRIP PROCESSING LINES In 2008, Danieli supplied a complete hot and cold mill complex for the MMK Metalurji project in Dortyol, Turkey. The supplied hot-dip galvanizing line was equipped with Danieli Kohler S-Jet air knives. Since then, the production mix of the hot-dip galvanizing line has been progressively expanded to include a higher percentage of thin strips with very thin coatings (including Z70). The initial air knives had become an impediment to an increase in processing speed, creating a bottleneck for higher throughput. The decision to install X-Jets, which had not yet been available in 2008, when the line was originally supplied, followed technical discussions and a thorough analysis of the expected production benefits. Thanks to the modular design of Danieli Kohler’s air knives, the revamping included the re-use of many parts of the existing equipment, minimizing the capital investment. Danieli supplied new X-Jet air knives with lip cleaners, new blowers with special piping, modifications to the existing roll rigs as well as electrical and automation equipment. The new air knives were installed during a scheduled, one-week maintenance shutdown. The performance increase provided by the X-Jets in terms of coating weight and line speed was immediately obvious. After the revamp, the hot-dip galvanizing line is able to produce Z100 at 180 m/min, and tests have shown

that the X-Jets can produce Z80 with 40 g/m2/side at 180 m/min. Productivity has increased by approximately 10%, with a payback time of less than six months for MMK. In January 2016, Danieli received the FAC for the new air knives. Contact: www.danieli.com

“How can lubricants help to reduce our steel mill’s operational costs?” Price isn’t the only consideration when selecting a lubricant; the overall cost benefit of selecting an advanced lubricant that will perform better over a longer period of time will ultimately enable more cost savings compared to a cheaper, less effective oil. Some advanced lubricants have potential energy efficiency benefits, too. Despite accounting for just 1% or 2% of operational costs, advanced lubricants actually have the potential to enhance equipment functionality and lifespan, reduce energy consumption, and delivering substantial cost benefits.
cy compared with the reference when tested in a worm gearbox under controlled conditions. Given the huge amount of energy required to power a steel mill, small reductions in energy such as this can translate into significant cost savings. In the paper industry – which used similar gearboxes to the steel industry – Smurfit Kappa in the UK switched to Mobil SHC™ 632 and was able to save $4,000 annually from just one gearbox.

5RGEKCN GSWKROGPV Right choice of lubricants may save energy costs Advanced lubricants, despite accounting for just one or two per cent of operational costs, have the potential to enhance equipment functionality and lifespan, reduce energy consumption and deliver cost benefits. Compared to conventional mineral oils, advancements in lubricant technology have provided significant benefits. They have led to extended equipment lives, longer oil drain intervals and improved energy efficiency of the equipment. Steel mill operators rely on a number of lubricants to ensure efficient and long-lasting operation of the equipment. Therefore, it is important to identify the most effective oils for the various areas of a mill. By selecting oils with proven energy-saving potential, steel mill operators may reduce costs.
