Modernization of plants and production facilities Traditionally, we publish the short range outlook by the World Steel Association presented at their annual meetings in October in every year’s last issue of MPT International. Also this year we stick to this custom. However, there is much more uncertainty about how things will develop. The steel associations around the world have been constantly updating their forecasts for the next months to come. No doubt, the steel industry has been facing headwinds, in particular from overcapacities, market turbulences and geopolitical conflicts. Worldsteel states: “There is an increasing risk associated with this economic slowdown [in China] and the consequent financial market volatility, which has become a global concern.” All this has already led to production cuts and, in some cases, even to the idling of works. While having to cope with these challenges, the steel producers have lacked incentive to invest. Nevertheless, there is always need to improve, for example, the need to reduce resource consumption, save energy or improve quality. The challenge is how to achieve the best in times of scarce budgets.

Dipl.-Ing. Arnt Hannewald

Plant suppliers have prepared for the current scenario by focusing more on modernization than on greenfield projects. So-called Technological Packages are en vogue, as they offer good value for a restricted investment budget. In this issue of MPT International, we feature several examples of technological solutions that may fall in this category and case studies illustrating the benefits of tailor-made modernization projects. It is most fascinating to see how plant suppliers of all sizes have immersed themselves in the modernization strategies of the steel industry to understand what is really needed. It is also good to know that there are reliable and proficient technology providers around, capable of offering high-value solutions even under the prevailing harsh market conditions.

After successful commissioning of a new coil compactor in 2013 and a second one in 2014, ArcelorMittal has now placed an order with SMS group for the supply of a third coil compactor of type HP 4700-PWT2. In addition to the mechanical equipment, the scope of supply includes the electrical equipment, machine automation and the complete hydraulic systems. SMS will integrate the new compactor into the existing plant environment and optimize all process interfaces. One of the technological benefits provided by the new compactor is that it will turn the coils automatically. This will make it possible to produce coils with eight straps positioned at equal distances from one another by four strapping units. This strapping method is particularly suitable for higher-strength grades. Delivery of the third coil compactor is scheduled for the end of 2015.

Eurofer market outlook. Revised data on the EU steel market suggest that demand could grow by 1.5% in 2015, on a par with the expected rise in activity of the EU steel consuming sectors. Third countries’ imports have increased to the highest quarterly level since the second quarter of 2011. According to Eurofer director general Axel Eggert, this ballooning of imports confirms fears that third country suppliers are the main beneficiaries of current market conditions. EU steel companies will continue to be exposed to difficult conditions, even as imports are predicted to experience some moderation in 2016. MPT International 6 / 2015

Output in EU’s steel using sectors rose by 2.1% year-on-year in the second quarter of 2015. As expected, output growth picked up some speed following a rather muted start in the first quarter of this year. In spite of slowing demand from the emerging markets, the weaker euro also helped Eurozone exporters to benefit from robust demand in the US, South Korea and India. Total activity in EU steel consuming sectors is predicted to rise by 1.9% in 2015 and by 2.5% in 2016.

World Steel Association 2015 annual conference held in Chicago, USA In October 2015, the World Steel Association met in Chicago for its 49th annual conference. This year’s annual conference heard from high-level speakers on topics including China’s economic prospects into the future and steel’s role in the global economy. The leaders of 75 steel companies around the world have signed the worldsteel Sustainable Development Charter. The conference also featured a discussion on the challenges facing the steel industry and the impact of those on the industry’s future. The World Steel Association (worldsteel) is one of the largest and most dynamic industry associations in the world. It represents approximately 170 steel producers (including 9 of the world’s 10 largest steel companies), national and regional steel industry associations, and steel research institutes. Members represent around 85% of world steel production. Every October, World Steel Association hosts the annual conference for its members, which usually begins with meetings of the executive committee and board. This is followed by a series of presentations and panel sessions. This year the 49th worldsteel annual conference was staged in Chicago, the capital city of the Ohio state, USA.

Short range outlook for 2015 – 2016 In its short range outlook for 2015 and 2016, worldsteel forecasts that global steel demand will decrease by -1.7% to 1,513 million t in 2015 following growth of 0.7% in 2014. In 2016, it is forecast that world steel demand will show growth of 0.7% and will reach 1,523 million t. The steel industry faces headwinds from various fronts. Commenting on the outlook, Hans Jürgen Kerkhoff, chairman of the worldsteel economics committee said; “It is clear that the steel industry has, for the time being,

reached the end of a major growth cycle which was based on the rapid economic development of China. Combined with China’s slowdown we also face low investment, financial market turbulence and geopolitical conflicts in many developing regions. The steel industry is now experiencing lowgrowth which will last for the time it takes for other developing regions of sufficient size and strength to produce another major growth cycle. We expect the current headwinds to moderate in 2016, but this is based on a belief that the Chinese economy will stabilize. Of particular concern is the vulnerability of the emerging economies to external shocks though we are also expecting some, like India, to show

resilience to the global slowdown. On a positive note, the recovery of steel demand in the developed economies, even though the momentum has weakened a little, remains on track.” In China, the economy has decelerated as the impact of the rebalancing measures on the investment and real estate sector turned out to be more severe than expected. As a result, activities in the construction and manufacturing sectors have slowed considerably. China’s steel demand is expected to decrease by -3.5% in 2015 and -2.0% in 2016, following its demand peak in 2013. There is an increasing risk associated with this economic slowdown and the consequent financial market volatility, which has become a global concern.


INTERNATIONAL INDUSTRY NEWS The performance of some key emerging and developing economies started to deteriorate in 2012 due to internal structural issues, lower commodity prices associated with China’s economic slowdown, and in some cases, escalating political instability. For example Russia and Brazil are experiencing severe contraction in steel demand. Geopolitical tensions and political instability in the Middle East, Africa and Ukraine continue to have a negative effect. On the other hand, steel demand in India and Mexico and other countries in the

to currency appreciation and a slowing energy sector. In the EU there is a broadening of the recovery momentum aided by low oil prices, low interest rates, and a weak euro. Developed Asian countries like Japan and Korea are expected to show negative growth due to adverse structural forces weighing on their economies. In 2015, steel demand in developed economies is expected to contract by -2.1%, but positive growth of 1.8% is expected in 2016. Steel demand in the world excluding China will grow by -0.2% in 2015 and 2.9% in 2016.

The 2015 sustainable steel policy and indicators report The sustainable steel policy and indicators 2015 report highlights how steel and the steel industry contribute to and perform in the areas of economic, environmental and social sustainability. It reports about the steel industry’s performance throughout 2014 against eight sustainability indicators, measured annually since 2003. Publication of the report reflects the steel industry’s efforts to continuously improve performance in sustainability, to demonstrate commitment, and to enhance transparency. Reporting is voluntary, and in 2014 a total of 147 companies worldwide participated in the study, up from 42 in 2004. Crude steel produced by companies who reported on one or more indicators for the 2014 fiscal year was 923 Mt, representing 55% of global crude steel production. Commenting on the industry’s performance, Edwin Basson, director general of worldsteel, said: “Data for sustainability indicators has been collected since 2004 and the industry has improved over that period in many areas. However, there are a number of challenges that we continue to face and in some areas our performance still falls short of our ambitions. We are working to address these as a priority and will not compromise on our commitments.” MPT International 6 / 2015

For environmental performance in 2014, average greenhouse gas emissions were at 1.9 tonnes of CO2 per tonne of crude steel cast and energy intensity was at 20.4 GJ per tonne of crude steel cast. Material efficiency indicator results showed that 97.6% of materials used on-site to make crude steel are converted to products and by-products. The environmental management systems (EMS) indicator demonstrated that 94.2% of steel industry employees and contractors worked in EMS registered production facilities, e.g. with ISO14001 certification. For social performance, the lost time injury frequency rate (LTIFR) was at 1.4 injuries per million hours worked in 2014 while the employee training indicator showed that employees (at both production & non-production facilities) received an average of 6.5 training days during the year. For economic performance, investment in new processes and products in 2014 was at 7.5% of revenue while economic value distributed (EVD) reached 954 billion US$ globally or 97.3% of revenue.

Seven principles highlight the steel industry’s commitments to improving the social, economic and environmental performance of member organisaMPT International 6 / 2015

tions. Edwin Basson, director general of worldsteel, said: “Our members are committed to the future of sustainable steel, for a sustainable society. Our collective belief is that sustainable development must meet the needs of the present, without compromising the ability of future generations to meet their own needs. Quite simply, we each need to take responsibility and act with purpose to achieve the targets we have set for the coming years.”

Safety and health excellence Worldsteel has recognised excellence in six safety and health programmes from Arrium, Essar Steel, Gerdau, Hadeed, NatSteel and Tenaris. Wolfgang Eder, worldsteel’s chairman, said: “The 2015 safety and health submissions and implemented programmes once again show that leadership of the CEO or chairman of an organization is a key element of any successful safety and health initiative. Leadership is undoubtedly essential in building a sound, safe and healthy work environment. We are very proud of the companies recognized this year for the improvement they have made for their employees, but also the positive impact they have made on the industry. There is no better way to improve safety performance than sharing the knowledge and experiences among peers.”

Arrium, South Australia, launched the ‘Swear By Safety’ campaign, a comprehensive cultural change process to shift belief around achieving Goal Zero and injury prevention behaviours at its mining and steel business as well as the broader community in Whyalla, South Australia. The campaign was well supported with unique and appealing materials through multimedia including TV, radio, print advertisements and social media. Overall, 800 people within the workplace and community took the ‘Swear By Safety’ oath, including the local mayor. Essar Steel, India, launched a ‘Process Safety Management’ (PSM) project in December 2010 with a baseline external audit by a third party, which was followed by further audits in 2012, 2014 and 2015. The project incorporates a number of different safety initiatives and aims at involving all employees and contractors. The initiatives include an online PSM portal, PSM campaigns, screening of PSM video films and a ‘Safety Rally’ which gathered over 3,500 employees. As a result, the PSM culture score evaluated by the third party audit has improved from 55% in 2010 to 92% in 2014. Gerdau, Brazil, developed a ‘Leader’s Proactive Index’ (LPI) which monitors and evaluates the execution and control of leaders’ safety activities. The LPI approach encourages lead-

The initiative, based on regular evaluations of the company’s leaders, has produced both qualitative and quantitative benefits and has resulted in a notable improvement in injury frequency rate and severity rate in 2014. Hadeed, Saudi Arabia, built a new user-friendly online ‘Environment Health Safety and Security’ (EHSS) reporting system, with investigation and action tracking features aiming to make the process of producing near miss reports accessible to all. An overall near miss analysis is carried out every month and every near miss is subject to a detailed analysis by the company’s safety department. The near miss analysis report helps the company to identify areas of concern that require attention and encourages employees to adopt a culture of EHSS reporting. As a result of this initiative, the number of near misses reported has increased almost tenfold, from 1,579 in 2009 to 15,433 in 2014. NatSteel Holdings, Singapore, implemented a ‘Total Workplace Safety and Health’ (TWSH) programme, a holistic approach to integrate its safety, health and well-being activities in 2014. This is a continuation of the safety excellence journey to cultivate a

safety and health culture in the workplace embarked on in 2008. The TWSH approach recognises that the work environment and the overall health, safety and well-being of employees are interrelated. With the implementation of various programmes, such as the ‘Occupational Hygiene’ programme, the ‘Wellness’ programme and ‘Health’ programme, the health of the employees has improved significantly and has resulted in the reduction of chronic diseases. Tenaris launched the ‘Safety Work Instructions’ project in 2010 to define best practices focusing on development, availability, training, adherence control and updating. The aim was to standardize behaviours among different teams and encourage management leadership through direct involvement in the approval and control process. The company developed 4,000 safety work instructions, available to all those working in operative areas, and around 8,000 inspections were performed in 2014. As a result, the total number of injuries in 2014 was reduced by 36% compared to 2010.

Steelie awards The 6th Steelie awards winners were announced at the annual dinner to close the 49th worldsteel conference. The trophies, known as Steelies, were

manufacturers in the world for metal making plants and machines, market leader in meltshops and plants for the production of long products, and second in the manufacture of plants for flat products. The second business (Steelmaking) concerns the production of special steels through the companies Acciaierie Bertoli Safau S.p.A. (ABS) and ABS Sisak d.o.o. (ABS Sisak). ABS is the number one steelmaker in Italy and among the leading ones in Europe in its field. Danieli Plant Making has largely achieved the set production targets, as the consolidated revenues show the

effect of a decrease resulting from the cancellation of nearly 85 million euros linked to the “intercompany� invoicing of the Rotoforgia plant to the subsidiary ABS S.p.A. (an activity which occupied the Italian workshops for most part of 2014/2015). Sales of ABS Steelmaking show the effect, with equal production volumes (approx. 1 million tons), of a decrease in sales prices linked to a parallel drop in the costs of raw materials, and during the financial year maintained a satisfactory level of margin and plant use. The group’s consolidated profit for the period has improved compared to


Danieli provides 65,000 hours per year of technical support and consultancy for productivity and quality improvement

the previous financial year, even if it shows a lower operating margin which is however substantially in line with the forecasts made at the beginning of the year. This is mainly due to the group’s financial management which, even if with a prudent approach, has obtained a very satisfactory result thanks to the good currency management. Moreover, the group’s net financial position has improved. As regards capital expenditure, in the Plant Making sector the development plan of the Danieli workshops in China and Thailand was substantially completed during the year, while the production ramp-up of the new factories in India and Russia is under completion. In the Steelmaking sector (ABS), after the conclusion of the first phase of investments at Sisak in Croatia, investments went on at Pozzuolo in Italy with the completion of the new reversing mills, the technological upgrading of the continuous casting machine MCC3, and the start-up of the new Rotoforgia rolling mill in September. The important investments made at ABS have a high innovative content which will enable the company to sig-

nificantly improve quality and widen the range of its products, thus covering new market segments in a competitive way. The group’s order backlog was in line with year-end figures of the previous year and well diversified by geographical area and product line. The number of employees of the Danieli Group

decreased by 470 units compared to 30 June 2014.

ther strengthen Danieli project execution and construction capability, and broaden Danieli Centro Aluminium products and stainless steel range. Fata, with headquarters in Pianezza, Italy and a workforce of approximately 200 employees, has a yearly turnover of about 150 million euros. Fata is divided into two main businesses: Fata EPC has experienced activity in the field of turnkey plant engineering, procurement and construction, with a first-class track record in the aluminium, chemicals and power markets. The second business, Fata Hunter has distinctive capabilities in the aluminium, steel and stainless steel processing industries. The acquisition of Fata Hunter will further broaden Danieli Centro Alu-

minium’s product range. This move will also integrate certain areas of Danieli competences in steel lines, with particular focus on stainless steel. The recent partnership agreement entered into between Danieli and Alcoa for the worldwide marketing of the Micromill™ technology will put Danieli Centro Aluminium on the cutting edge of technology in the aluminium market.

Outlook and strategies for the Danieli Plant Making segment The world steel market is undergoing a period of restructuring in 2015, with a forecast of stabilization for 2016 and improvement for 2017. Quantities in

some markets are increasing, but prices remain low due to the competition of China, Russia and Ukraine. It is clear that there is a need for a shared and joint strategy above all in Europe, in order to reduce evident differences in development, eliminate the inefficiency present in some countries, and promote a greater competitiveness in the weaker economies. Some countries are already showing clear signs of recovery, while others are still penalized by delays in the reforms required to modernize their structures. This confirms the need for a greater global coordination to sustain growth through medium and long term development plans to foster new investments in infrastructures and the upgrading of the existing ones. The prospects of global growth for 2016 show an improvement with a foreseen GDP (gross domestic product) development of 3.8%. The Danieli Group will continue to consolidate and expand its activities to ensure an increased competitiveness in terms of innovation, technology, quality, costs, productivity and customer service; Danieli is renowned not only for its plant-making capabilities but also for its manufacturing ones: in Europe with noble and high-tech products, in Asia with the design and manufacturing of consolidated and tested products with the same European quality. Danieli is defining a new organizational model of the group to develop its present structure in a way which better reflects the emerging needs of the markets. In particular, to consolidate these strategies, the group has decided to strengthen the Danieli Academy for the development of the juniors, the updating of the seniors and the management and enhancement of talented youths. Danieli continues to pursue high rates of innovation, efficiency and quality of customer service; it follows that the team excellence plays a very important and strategic role for the company’s success. The importance of managing with great attention the enhancement of people’s potentials and skills to ensure that the group staff training is in line with the best practice is therefore confirmed.

consumption and increase melting efficiency. The system contains automatic melting profiles and adapts process parameters when required. This increases productivity. To ensure a high degree of reliability in a rough industrial environment, robustness and operational safety were a main focus during development. Amortization of Melt Expert may be achieved within less than nine months. For existing melt shops, Primetals Technologies offers upgrade kits to convert Arcos and Simelt systems to the new technology.

Embedded controller platform Melt Expert is based on an embedded controller platform, in which the system is split in a PLC part and a PC part. This new concept unifies the advantages of both platforms concern-

ing flexibility, robustness and computing power, which is necessary for fast and complex calculations as well as high dynamic HMI. Control signal handling is done within the PLC part which simplifies the integration into the automation environment. Intelligent signal interface modules ensure very fast and accurate data sampling with on-board signal preconditioning. Acquired data from hydraulics, mechanics and electrics is put in relation to actual operating conditions. In this way the electrode control system itself and its auxiliary systems are permanently monitored. So called health checks are performed automatically in regular intervals in which the functionality of measurement loops and output circuits are verified without disturbing the process. Continuous signal collection in combination with long-term-trend analysis allows the detection of shifts, deviations and creeping in malfunctions in a very early stage with the aim to predict a possible event or damage, before it happens. Based on actual process conditions, control parameters such as set points or controller gains are automatically adapted by the system. Arc length will be modified according to process needs. This results in a higher melting efficiency and reduced energy consumption. A new algorithm is avoiding arc extinction and increase the power input during boring phase. An integrated loop gain linearization model transforms individual mechanical furnace characteristics and uniforms the control loops. Thus the parameter setup will be simplified which results in faster performance run ups and less


STEELMAKING time needed for optimization. Standard state of the art protection functions are included as well as more advanced modules like countermeasures against electrode oscillation.

Screens provide conditioned information for different user needs Target group orientated screens provide conditioned information for different user needs like melt shop management, electrical/mechanical maintenance, operators, etc. Designated screens support optimization

and parameter tuning for process experts. Regularly revisions are simplified by a special maintenance mode. A novel touch screen design allows simple and fast access to process relevant data and displaying key values such as actual consumption figures, melting time or regulation quality in the form of bench mark reports. Should there be a significant deviation from normal process parameters, related information comes alive and will be indicated. For fully automated process control additional packages like foaming slag control, melt down control and thermal furnace balancing are available.

Conclusion Benefits of the new electrode control system for EAF and ladle furnaces are reduced energy consumption and increased melting efficiency due to auto-adaptive regulation algorithms. Higher productivity is ensured by automatic melting profiles and process parameter adaptation. The system is highly reliable due to main focus on robustness and operational safety in an industrial environment. Process quality is ensured due to target group orientated screens and highly sophisticated data recording and evaluation. Amortization can be within less than nine months.

Stressometer® Systems. Extended actuator teamwork.

The long standing problem with flatness control in multi actuator mills is now solved by ABB. To optimally make all mill actuators work together as a team is a complex task. Different actuator combinations will in these mills give the same flatness effect. The problem is to select the one actuator combination with the minimum actuator movement. The ABB patented method of Extended Singular Value Decomposition (ESVD) will optimally make this selection and make your actuators work together as a genuine team.

››› CONTINUOUS CASTING – SPECIAL EQUIPMENT

Precision measurement system KPETGCUGU GHƂEKGPE[ QH UVGGN production at the continuous caster To minimize material loss in cutting-to-length operations, measurement systems are indispensible. However, due to the inaccuracy inherent in the working principle of many systems, caused for example by slippage, wear or dirt, producers often have to add a VLJQLƂFDQW VXUSOXV TXDQWLW\ WR WKH PLQLPXP SURGXFW OHQJWK JXDUDQWHHG WR WKH FXVWRPHU 7KLV PHDQV WKDW ZLWK HDFK FXW WKH SURGXFHU ŔJLYHV DZD\ŕ D FHUWDLQ TXDQWLW\ RI PDWHULDO LSV measurement system positioned above the cast strand in front of torch cutters (left)

In continuous steel casting plants, torch cutting is performed at strand speeds (i.e. casting speeds) ranging between 0.5 and 5 m/min. In every continuous casting plant, the mould is the core equipment as it determines the format of the strand. The liquid metal is poured into the mould, cools down and solidifies as the strand moves on. The strand speed and the cooling pattern both have an effect on the cooling and solidification process. The strand speed is crucial to the internal quality of the final product. In the worst case,

if the outer skin is not thick enough to provide sufficient strength, the strand will break. These negative effects can be avoided by continuously measuring the strand speed and controlling it in accordance with the process requirements.

How long and how fast is the strand? When cutting slabs, billets or blooms to length, also the velocity measurement plays an important role as a complement to the length measurement because the strand is constantly moving on while being cut. In order to obtain a clean and straight cutting edge, the speed of the cutting unit must be adjusted to the speed of the moving strand. Otherwise, also the slant of

the cut would have to be taken into account in addition to the minimum length. Therefore, knowing precisely the speed and the length of the strand is an important factor for process optimization and consequently also for cost reduction. In principle, various methods are available to perform the relevant measurements, however, many of them having severe disadvantages: When the length and the speed of the strand are recorded with measuring wheels, inaccuracies are unavoidable. Inaccuracies result from the fact that the diameter of the wheel changes because of wear or contaminations such as scale. Therefore continuous maintenance, examination and calibration are required. Moreover, such tactile measurements are always influenced by slippage as the oscillating movements of the mould are transferred to the strand. Therefore, there will be a slight “jerk” from time to time. The same applies when speed and length measurements are derived from the rotational speed of the driving rollers recorded and evaluated by rotary encoders.

Effective solution: optical, non-contact and wear-free measurement Therefore it is not surprising that non-contact optical measurement systems have become the prevailing solutions in steel mills. The Laser Surface


CONTINUOUS CASTING – SPECIAL EQUIPMENT Velocimeters (LSV-2000) from Polytec, for example, have been specifically developed for precise speed and length measurements in rough environments. These systems are wear-free and do not require any maintenance even when in operation around the clock. Moreover, it is easy to integrate the highly reliable measurement data provided by these systems into process control. The Laser Surface Velocimeter uses the differential Laser Doppler principle and evaluates the laser light scattered back from a moving object. Unlike conventional non-contact methods, the LSV recognizes any standstill of the strand and reliably detects the direction of movement. The high precision and reproducibility of this non-contact measurement increase quality and reliability. For the user, this pays off quickly. Just by reducing the allowance of material for cutting inaccuracies by a few millimetres, payback periods of about one year can be achieved. The optical measurement systems are easy to install and commission. The devices are mounted about 1.5 m above the strand and are immediately ready for use. Commissioning is carried out by Polytec experts. Only the application-specific parameters will have to be entered. The training effort for this task is negligible; once in operation, the LSV does not require any operator input. A further advantage is that despite the rough environment the measurement system does not have to be protected by additional cooling measures. The protective housing with integrated cooling water pipes is so effective that there is no need for any additional protective measures. This saves the plant operator time and money.

Practice-proven in rough operating environments The measurement system is designed for ambient temperatures of up to 200°C and has proven highly successful in harsh industrial applications. For example, an LSV system was installed in a steel mill at a cross beam near the outlet of the strand, directly in front of the torch cutters. For cooling, process water of 31°C from the water cycle was fed into the housing. Despite the high inlet temperature, the cooling

performance was sufficient to protect the measurement system. The LSV measurement system was tested to simulate a problem in the cooling water supply. The water supply was interrupted and the temperature development was observed. Only after approximately 15 minutes did the temperature reach a value critical for the sensor. When the cooling water was circulating again, the temperature dropped to a safe level within just a few minutes. As process water may become too warm, especially in a warm climate, it was tested to use tap water instead. The temperature in the cooled protective housing never exceeded the level of 25°C. Therefore, the temperature at the measurement head, which should not exceed 45°C, was less than 30°C. The massive housing has sufficient reserves to work reliably in environments of higher temperatures than in the test environment. Due to the robust, high-precision non-contact measurement systems, economic efficiency and process safety can be markedly increased in any continuous casting process without requiring additional cooling measures to be provided by the plant operator.

Conclusion In continuous casting processes, as in any production process, material loss must be kept as small as possible in order to guarantee economy of

production. The use of the high-precision, non-contact LSV measurement systems, which are designed to withstand even the rough operating conditions directly above the hot cast strand, a considerable savings potential can be tapped, increasing the overall economic efficiency of the continuous casting process.

››› MODERNIZATION

Elbe-Stahlwerke Feralpi upgraded the continuous billet caster The German steel producer modernized the billet production plant in order to improve the internal and surface qualities of the billets, and to increase the production capacity by 20 percent. This was achieved by installing a new machine head, which included DiaMold molds and a retractable DynaFlex oscillator, as well as by optimizing the secondary cooling. Elbe-Stahlwerke Feralpi GmbH (ESF), a German steel producer and part of the Feralpi Group, has issued the final acceptance certificate for a modernized, five-strand continuous billet caster in its Riesa plant. Primetals Technologies received the order in May 2014. One major reason for winning this order was the good results Feralpi had obtained with the modernized, four-strand continuous billet caster in Acciaierie di Calvisano, Italy, which Primetals Technologies had also modernized at the beginning of 2013. The aims of the project at the Riesa works were to improve the internal and surface qualities of the billets, and to increase the production capacity by 20 percent. This was achieved by installing a new machine head, which included DiaMold molds and a retractable DynaFlex oscillator, as well as by optimizing the secondary cooling. The new plant has a modular design, and was pre-assembled to keep installation and downtimes short. The five-strand continuous billet caster owned by ESF in Riesa was installed in 1994 by a third-party supplier. It had an annual production capacity of around one million metric tons of billets with square cross-sections of 130 x 130, 140 x 140 and 160 x 160 millimetres. The plant has a machine radius of six metres and reaches casting speeds of up to 3.8 metres per minute. It casts low and medium-carbon steels, which are further processed in a wire rod mill in the Riesa plant.

Improvements to the machine head and secondary cooling Retractable DynaFlex mold oscillators were installed to increase capacity. This solution enables the mould on a strand to be exchanged without interrupting the casting process, increasing both the productivity and the flexibility of the casting plant. All mechanical connections are released hydraulically at the touch of a button. The complete machine head, including mold and oscillator, is moved from the casting position to the maintenance position on a mobile platform. The time between stopping and restarting the strand to change a mold is between just 15 and 20 minutes. In this time, the mold is exchanged, the dum-

my bar is brought in, and the mold is prepared for casting. The existing secondary cooling was converted and extended by adding a fourth zone to ensure optimal cooling even at higher capacities. To increase product quality, the casting plant was equipped with new DiaMold molds. The technical features of the oscillators include stroke adjust capability during operation, and the option of selecting from a range of sinusoidal and non-sinusoidal oscillation parameters. An OsciMon system monitors the movements of the molds, and visualizes the measured values of frequency and stroke in all three dimensions. The equipment installed during the course of the modernization was designed to keep downtimes as short


MODERNIZATION as possible. The modular design concept was selected for its focus on ease of installation. System parts were also pre-assembled and tested according to the proven “Connect & Cast” plant conversion philosophy to shorten installation times on site. As agreed, the

plant was converted during the 2014 Christmas stoppage.

Conclusion Technical improvements to the machine head and the secondary

Layout of the ArcelorMittal Dunkirque hot strip mill

Tailor-made drive train upgrade for the rolling mill of ArcelorMittal Dunkerque Steel markets have been demanding increasingly higher-strength rolled products. Due to the higher rolling forces required to produce these grades, drive trains of hot rolling mills are exposed to higher loads. Within the framework of a study, the mechanical and electrical components of existing drive trains have been analyzed. Innovative solutions have been developed to upgrade the mill drive system with powerful and reliable components. ArcelorMittal Dunkerque has recently upgraded the drive system of its hot strip mill. The objectives of this investment were to improve the reliability of the plant and expand the product mix towards higher-strength grades. The upgrade was initiated by a study provided by SMS group covering the overall capabilities of the hot

strip mill. The study had analyzed the existing product mix and the failure statistics of the existing drive components and had provided a load prediction based on the planned future product mix. From 2010 to 2014, the main gears of both the roughing mill and the finishing mill were replaced. New gear units were manufactured in the SMS group workshops. All upgrading measures were performed during scheduled annual shutdowns in order to minimize production losses. Thanks to the preassembly of the gear units, the time frame for the installation on site could be kept very short.

ArcelorMittal Dunkerque integrated iron and steel works The integrated iron and steel works in Dunkerque (France) is part of ArcelorMittal Atlantique. It makes flat steel products. The process route comprises a coking plant, a sinter plant, blast furnaces, BOF converters, continuous casters and a hot strip mill. The 2,040 mm wide hot strip mill went on stream in 1963. It is a fully continuous mill comprising five roughing stands, seven finishing stands and three downcoilers. The nominal production capacity amounts to 5 million t/year of coil.


MODERNIZATION Roughing stands of the hot strip mill are continuous stands. Their drive trains comprise a main gear and a pinion gear.

Study of options for modernization After more than 40 years of operation and due to increasingly higher loads, the reliability of all drivelines had been dramatically decreasing. The gear units required high maintenance efforts. It was doubtful whether the drive units would be able to cope with any further increasing loads that would result from future requirements. At that point, ArcelorMittal Dunkerque awarded SMS group the order to systematically analyze the drive trains of the roughing mill and the finishing mill. For almost one year, SMS group studied in detail the operating conditions of the mill. Based on the mill data (e.g. pass schedules, material specifications, stand loads) and measurements of the actual rolling torques, forces and speeds, the dynamic behaviour of the complete drive train from the motor via couplings, gears and spindles to the work rolls was simulated. By this approach, it was possible to determine the torques acting on the drive components, assess the mechanical limits of the gears and evaluate different measures for the improvement of the situation. A second part of the study was a rolling simulation of the current and a future product mix. This involved the comparison of the mill concept based on continuous stands with roughing mill concepts using reversing stands. The evaluation proved that the current configuration would also suit ArcelorMittal’s future demands. As a result, the study recommended the installation of new main drive motors and the upgrade of the main gear units of the roughing mill and the finishing mill.

Maintenance cost savings would be achievable above all by a suitable rating of the new drive components. In order to save costs on spare parts, the design of the drive components was to be unitized wherever possible. The motors for the roughing and finishing mill drives were kept identical so that the number of spare parts could be minimized and their multiple use would be possible. The bull gears of the drives are expensive equipment and their delivery time is usually very long. Therefore their design was unitized in order to be able to use the gears in various drivelines. The number of coupling types used in the complete roughing and finishing mills could be reduced to only five sizes to be stored as spares. To minimize the risk of failure, the sequence of replacements was selected such that the weakest drivelines were to be replaced first. The theoretical calculations of the reserves of the existing main gearboxes clearly corresponded to ArcelorMittal’s practical experience as reported in the statistics of failures and damages

of the drives occurred during the past few years. Accordingly, the decision was made to first exchange roughing stand R5, then, one year later, R2 together with R3 and finally, in 2012, R4 together with the main reducers of finishing stands F2 and F3. Because of an unpredictable failure of the existing gear of finishing stand F1, which occurred during the project, the F1 reducer had to be exchanged during an unscheduled shutdown. The modernization of the drivelines was completed in summer 2014 with the installation of the new main reducers of F4 and F5. The design of the foundations and site planning were provided by ArcelorMittal Dunkerque in cooperation with SMS group. The installation work was performed by proficient subcontractors and supervised by SMS group specialists. Every shutdown was a challenge in terms of work sequence planning and coordination of the teams responsible for the electrical drives and the gearboxes. Whereas the installation of the drive components for roughing stand R5 was quite easy to perform, the

Modernization strategy The main target of the modernization project was to maximize the availability of the drivelines. Further targets were to minimize ▪ the maintenance costs, ▪ the costs for spare parts, and ▪ the risk of failures during the project.

complexity grew with each of the following shutdowns for the other drive trains. Successful implementation had only been possible thanks to the very close cooperation between ArcelorMittal Dunkerque and SMS group as well as the suppliers of the main drive motors.

Gear manufacturing The gear units were completely manufactured at the SMS group workshop in Hilchenbach, Germany. All gears for this project are equipped with

double-helical case hardened toothing. The largest case-hardened gear was manufactured for roughing stand R3. That one has a diameter of nearly 4,500 mm, a width of 1,300 mm and a weight of 40 t. Mounted together with shaft, bearings and coupling, the dropin set weighs 75 t. Gear manufacturing in the workshop starts with submerged arc welding the hub and rim to the wheel body. To satisfy highest requirements regarding accuracy, gear cutting is performed in three steps: slotting, rough-cutting and finish-cutting. After case hardening, the

tooth flanks are ground with highest accuracy on a modern profile grinding machine. Also the gear housings were welded, machined and assembled in-house at the SMS group workshops in Hilchenbach. There, all gear units were pre-assembled and the contact patterns of the gear tooth were preset. After a final check, the units were disassembled into suitable sub-units and transported to the site for installation.

Conclusion The study of the entire hot strip mill provided deep insight into the existing pre-modernization situation and provided the basis for specifying, rating and designing the new drive trains. Based on those findings, a tailor-made concept for the modernization of the drive trains for the entire hot strip mill could be drawn up. SMS group manufactured all gearboxes in their own workshops in Hilchenbach and delivered them to the ArcelorMittal plant in Dunkerque. All mill stands operated under full production load immediately after erection on site.

the company needed to find a suitable solution to restore the correct geometrical characteristics of the finishing stands in order to guarantee stable strip rolling parameters. While guaranteeing a high performance level of their production equipment, steel producers constantly strive for cost savings, especially in economically difficult times as we are going through at the moment.

On-site machining of the housings of the hot rolling stands With this objective in mind, in April 2014 ArcelorMittal Temirtau chose Danieli as its partner for a project which involved the restoration of the stands’ geometrical dimensions. The main targets of this project were to improve the quality of the rolled material and to dramatically reduce the failure

rate of the work roll bearings. Among others, the installation of DanOil oil film bearings was intended to save costs on spare parts and reduce downtimes due to bearing failures. Brand new mill stand housing windows feature very tight tolerances, ensuring that the roll chocks are stably and accurately positioned and the rolls properly aligned. When a mill stand has been in service for many years, the condition and positioning of the mill stands deteriorates due to various factors. This leads to problems due to the incorrect positioning of work and back-up rolls and excessive movement of the roll chocks in the mill stand.

The geometrical re-alignment of the finishing stands was executed by on-site machining. The aim was to reestablishing the originally tight tolerances and achieve an alignment as precise as in brand new mill stands. The scope of that activity encompassed the re-alignment of the mill windows of all seven finishing stands in two phases. The stands had been in operation since 1959. The first phase was successfully completed in November 2014 during a mill shutdown of only 12 days. The second phase is planned for the end of 2015. The purpose of the activities was to restore the proper roll stack alignment (alignment of work and back-up

rolls) in each stand, between the stands and with respect to the mill’s central axis. The work performed has resulted in an improvement of the quality of the final rolled product. Strip defects caused by roll chattering, swinging and crossing have been eliminated. Extensive engineering and equipment manufacturing for phase 1 had been carried out in record time, considering that not only the on-site activities had to be prepared but also a great number of high-quality spare parts and improved equipment had to be supplied to the customer, namely: ▪ new bending blocks with DanLiner wear plates, ▪ DanLiner wear plates for housing and chock, ▪ base plates and inter-stand rails, ▪ work roll and back-up roll clamps, ▪ back-up roll sledge with load cell cases, ▪ spherical bearings, ▪ grease lubrication unit with piping. The project was carried out by a joint team involving staff from the Danieli Service headquarters and the Danieli Volga local branch operating in Eastern Europe. During the shutdown more than 50 persons were involved as well as five on-site milling machines and three laser measurement stations. Starting at the first shutdown day, a complete 3D finishing mill alignment was performed in order to define the proper reference planes for the milling. To this end, the stands had been stripped off the main components, such as wear plates, bending blocks, inter-stand rails and clamps, and the portable milling machines for vertical surfaces (liners and bending block seats), horizontal surfaces (base plates and inter-stand rails) and front surfaces (clamps) had been put in place. The machining phase included the restoration of existing holes and the drilling of new fixation points where necessary. When the machining was completed, new, customized stainless steel wear plates were installed and connected to a new grease lubrication unit allowing a dedicated, advanced grease lubrication pattern. After re-assembling the stand equipment, the mill was restarted perfectly on time. MPT International 6 / 2015

Along with the above mentioned activities on the hot strip mill (i.e. restoration of finishing stands and chocks) the outdated sealing system had to be converted to the reliable, state-of-theart DanOil solution. The new DanOil sealing for the chocks of the back-up rolls reliably avoids water and scale ingress at the chocks and into the lubrication circuit of the oil film bearings, an additional factor providing for a long service life of the DanOil bearings. The key facts of the hot mill revamp can be summarized as follows: ▪ Very tight project execution time schedule (five months). ▪ Engineering was completed within a record time of 45 calendar days, with the engineering for long-lead items ready within 72 hours from order confirmation. ▪ 60 t of stainless steel wear plates (DanLiner 1174) were manufactured in less than 12 weeks, with very high dimensional accuracy (max. 0.05 mm parallelism and planarity) and excellent surface finishing (Ra <0.8). ▪ On-time plant restart after successfully completing on-site activities in only 12 days.

Danieli’s proposed approach to maximize the yield by replacing but a minimum portion of the existing equipment had been the winning point: the highest level of customer satisfaction was achieved with reduced investment costs. Installation and commissioning activities were concluded on time, two days before Christmas 2014. ArcelorMittal Temirtau greatly appreciated the support and help during the installation, commissioning and test phases rendered by Danieli Advisory Service. The following contractual performance targets have meanwhile already been achieved: increase in entry backtension, the possibility of rolling wider strips, increase in rolling speed, strip centering within an accuracy of ±3mm at the entry into the first stand and improved strip cleanliness . ArcelorMittal signed the Final Acceptance Certificate later in January 2015, immediately after rolling the first wider strip material for galvanizing. A Stressometer Roll will measure and guarantee strip shape parameters within a tolerance of the 25 I-units.

Outokumpu Nirosta to upgrade rolling-oil treatment technology Clean oil for bright coils: in the framework of the modernization of its 20-roll cold strip mill at the Krefeld (Germany) site, Outokumpu will revamp the existing rolling-oil treatment plant. The Outokumpu group is a global leader in stainless steel strip with production facilities located in China, Finland, Germany, Mexico, Sweden, the UK and USA, and with a global sales and service centre network. The Outokumpu Nirosta Krefeld site is one of four cold rolling production facilities in Germany. Here, a 45 years old 20roll cold rolling mill “SG 3” in monoblock design was upgraded recently, allowing this mill to be used also for rolling ferritic grades in thin gages and high-gloss quality (2R bright annealed).

SMS group, Düsseldorf, Germany Contact: www.sms-group.com E-mail: communications@sms-group.com MPT International 6 / 2015

In March 2015, SMS group received an order from Outokumpu Nirosta encompassing the upgrade of the rolling-oil treatment plant, making it suitable for the production of these high-gloss grades. A part of the equipment will be retained and continued to be used. Key equipment to be newly installed includes a dirty-oil tank with automatic pre-separation and the ultra-fine filter system SUPAFINE® developed by SMS. In future, vertical filter pumps will convey the rolling oil containing contaminations from the rolling process out of the dirty-oil tank to the SUPAFINE® filter system, where it will be cleaned. The cleaned oil will be fed to the clean-oil tank and reused in the rolling mill. The mixture of rolling oil and abrasive material resulting from the backwashing of the oil filters will be treated in a second

filtration stage and the thus recovered rolling oil will be recycled back into the system. The employed backwashable filter elements achieve an extremely high filtration grade without requiring any filter aids – and hence without the otherwise arising high consumables and disposal costs. The performance and economic efficiency of the SUPAFINE® filter system has been proven by the fact that as many as 210 of these filter units have already been installed worldwide. As requested by Outokumpu Nirosta, SMS will perform and complete the work on the mechanical equipment of the mill stand and on the rolling-oil treatment plant within a very tight time schedule in the course of the year 2015, guaranteeing that Outokumpu Nirosta can start producing the desired grades on this mill before the end of the year.

Upgrade of turbine blowers in blast furnace plant ENVIRONMENTAL PROTECTION In order to reduce energy consumption at blast furnace No. 5, ArcelorMittal Galati, Romania, has invested in an upgrade of a set of turbine blowers which inject cold air into the blast furnaces. The new system is based on a state-of-the-art operating system that allows for the two units to be handled, monitored and controlled automatically. The project involved the redesign of the rotors and the diaphragms of the two compressors and turbines, the maintenance of all technological control, balance and command circuits. The blowers are now more efficient, more flexible in the way they

can be deployed, and more reliable. They use only 32 to 40 t/h of steam, compared with 70 t before the modernization. With the steam saved, the company is now able to generate electricity that can be used in the steel production process. A high level of automation has also been implemented, improving the efficiency of the operation. The investment was part of ArcelorMittal Europe’s ‘Energize’ project aimed at reducing energy consumption by 15% over the next five years. Contact: www.arcelormittal.com

Big data technology to optimize material use in oxygen steelmaking STEELMAKING To optimize the consumption of ferroalloys and supplementary materials during steel production in the oxygen-converter plant, Magnitogorsk Iron and Steel Works (MMK) has signed an agreement with Yandex Data Factory to develop a mathematical model for steelmaking in MMK’s oxygen-converter plant and to use this as a basis for developing related software. IT specialists from Yandex Data Factory and specialists from MMK are currently analyzing information covering the

oxygen-converter plant operations over previous years. A machine learning algorithm will be incorporated into the mathematical model that is being developed based on corporate information available on the Apache Hadoop platform. The final software solution will receive data on the original composition, original weight and requirements regarding the chemical composition of the steel produced, and the mathematical model will help it indicate the optimal amount of ferroalloys

and supplementary materials to be used during steelmaking. The Sniper project employs big data technologies, processing large sets of data in order to improve management processes and optimize production. The final stage of the project is expected to include a quality check involving a series of experimental steelmaking processes in which additive composition is based on the system’s recommendations.

Ladle slide gate valve with three plates CONTINUOUS CASTING The gas-tight three-plate ladle slide gate valve, FT3 GT, offered by Knöllinger Flo-Tec, has been designed for applications with very high demands on the steel quality. The slide gate valve, which consists of three plates, features a closed housing with high-temperature-resistant seals. It can be applied as an inert gas barrier acting as a shielding from the outside atmosphere. The gas is passed through the gate, past the collector nozzle into the funnel or shroud. This produces a combined casting stream and slide gate shield. When developing the FT3 GT slide gate valve, emphasis was also placed on ease of use. To achieve this, the centre plate is mounted in a cassette, which can be swung open to provide free access to the slide plate. The gate valves are available in two diameters, 65 and 100 mm.

Roll bite lubrication ROLLING MILLS As a result of roll lubrication introduced to its 4-high Steckel mill by Quaker Chemical, Nucor Steel Tuscaloosa has been benefiting from significant extension to roll service life and a notable reduction in mill torque. To further understand the impact of roll lubrication, a trial was performed which yielded the mechanism and advantages of backup roll lubrication in the reversing hot rolling mill: Fewer roll changes are needed with lubricated backup rolls, as the normal pressure and friction traction between the backup and work rolls are reduced. Roll bite lubrication lowers the mill separating force and torques by increasing the slipping zones and counteracting the length of the breaking zone. Bite and roll slippage are no longer factors with the presence of lubrication. Contact: www.quakerchem.com

of the system. Voith CT-P couplings completely eliminate these disadvantages, as they require no lubrication or maintenance and can operate around the clock 365 days per year. Operators save costs when calculating this over the life cycle of a plant. A CT-P coupling usually has a longer lifetime than the units connected to it. The longer lifetime is achieved thanks to the completely different physical concept employed by Voith. The integrated rubber elements prevent metal-to-metal contact as is customary in a gear coupling. At the same time, they dampen the forces of inertia occurring when drives are switched off. Another distinctive advantage is that silicone elements can be used if needed, allowing the CT-P coupling to resist heat up to an ambient temperature of 130°C. The couplings are designed for torques of up to 200,000 Nm and speeds of up to 7,200 rpm. They are usually installed directly between the electric motor and the roller conveyor.

Online monitoring concept for trunnion bearings in converters STEELMAKING A new comprehensive online monitoring concept for the trunnion bearings and gears of converters has recently been introduced by Schaeffler. The system incorporates several monitoring concepts, namely acoustic emission measurements, oil particle analysis and grease condition checking. Acoustic emission measurement is an ideal method for slowly rotating trunnion bearings such as those used in converters. The otherwise usual method of measuring vibrations cannot be used reliably here, since the speeds are not high enough to generate sufficient energy to measure the structure-borne noise during overrolling of damaged areas of the bearing. Acoustic emission measurements, on the other hand, utilize the effect that plastic deformation or breakages occur in materials that are subject to loads beyond the elastic lim-

it. This defect leads to a concentration of stresses followed by the formation of cracks and, ultimately, to a sudden release of the tension in the material. This short process generates an acoustic emission event that moves away from the source in the form of an ultrasonic wave and that can be measured. Wear in bearings or gearings manifests itself well before impending failure in the form of abraded metal particles. If this abrasion is measured and monitored, damage to gearboxes lubricated with oil circulation and plain bearings can be detected at an early stage. The FAG Wear Debris Check device measures the number of particles in the oil and transmits key values to the upstream monitoring system and records and evaluates the particle concentration according to size and material. More than half of all rolling bearing

failures are directly attributable to lubrication. Lubrication conditions, physical grease aging, or the proportion of solid and liquid contamination such as water in the lubricant have a decisive influence on bearing life. By using the FAG GreaseCheck sensor and the corresponding analysis unit, it is possible to detect any changes in the condition of the grease during operation, long before any damage to the rolling bearing occurs. This means grease changing can be precisely planned and the operating life of the bearing can be extended. Moreover, it allows switching from scheduled relubrication to relubrication according to requirements. As part of the monitoring strategy, FAG ProCheck monitors over 60 ascertainable key values and the process parameters. Contact: www.schaeffler.com

Low-wear and low-maintenance side guiding system HOT ROLLING Voestalpine Stahl will install additional Eco Slide Disc systems at the entry side guides of coilers 3 and 4 in the hot strip mill. Eco Slide Discs developed and supplied by Primetals Technologies have already been in continuous, successful operation at one guiding side of coiler 3 since August 2014. Eco Slide Discs can be used continuously for four weeks, whereas conventional wear strips usually last only two or three days. The new side guides have an inherent self-cleaning effect. This reduces the risk of material deposits falling on the strip and damaging its surface. The rotatable Eco Slide Discs are mounted on a maintenance-free, rugged geared beam. They are installed vertically between the table rollers and automatically and synchronously rotate through a selectable angle after a variable number of strips have passed. While, when using conventional wear plates, the strip always cuts into the material at the same point, with Eco Slide Discs the wear is evenly distributed around the entire surface of the circular ring. This does not only extend the service life of the wearing parts, but also the period of continuous operation of the entry side guides from the previous two or three days to four weeks. The periodic and gradual rotation of the discs means that only small amounts of rubbed off material from the guided strip edges adhere to the discs. Such deposits are rubbed off by the following strips. This

self-cleaning effect of the Eco Slide Discs eliminates the manual cleaning of the wear strips required for certain strip qualities to prevent deposits from the strip edges falling off and damaging the surface of the strip. Contact: www.primetals.com

Universal encoder system for implementation of safety functions SPECIAL EQUIPMENT When rectifying faults, setting up machines or performing test runs, it may sometimes be necessary to intervene while the machine is running. This poses a safety risk to the operating personnel. The universal encoder system U-ONE- Safety offered by Johannes Huebner Giessen supports machine builders and system operators in their endeavours to prevent accidents. With the U-ONE-Safety system it is easy to implement motion and position-dependent safety functions such as safely-limited speed (SLS), safe direction (SDI) and safely-limited position (SLP). The system offers safe position, speed and error switches, safe absolute encoder interfaces and current or incremental outputs. The modular concept behind the system makes it possible to create the right solution for the respective application. Two different versions are available: U-ONE-Safety-Compact, which consists of the basic unit and the attached modules housed in robust casings, and U-ONE-Safety-LWL, which features a basic unit in a robust housing connected to the cor-

responding modules in the switchboard via fibre optic cable. Contact: www.huebner-giessen.com
