Sophisticated technologies promise JKIJGT RTQƂVCDKNKV[ KP steel production MPT International starts the new year with a report about one of the milestones achieved in 2016 – a greenfield project by Austria-based Voestalpine: the new direct reduction plant built in Texas, USA. The company is continuing to systematically drive forward its expansion in North America. What is more, the completion of the direct reduction plant in Texas marks the start of a new era at the company. Voestalpine has settled a powerful ironmaking base far away from their traditional integrated iron and steel works in Europe. The multi-year project was well-covered by business media in both regions, in the USA and in Austria. MPT International has summarized the main technical details in an article in this issue. We also provide links to highly informative videos about the plant and its process technology. Another article, which goes even more into technical details, demonstrates the potential of automotive shredder residues used as chemical energy in the EAF. A competitive route has been developed to recycle and valorize such material. It comprises two stages: first, the recovery of the metallic share and, second, the conditioning of the plastic mixture to formulate synthetic carbon. This feed material has been tested as a partial substitute for the metallurgical carbon (i.e. pulverized coal) injected into the EAF.

There are more articles featuring very interesting steelmaking technologies and investments: Taiwanese specialty steel and alloys producer Gloria has started a fascinating minimill project. The company is the largest producer of specialty alloys in Taiwan and a globally leading supplier of specialty steels, superalloys and titanium alloys. The new melting, casting and refining facilities will set new standards in terms of both productivity and quality for this range of products. Commissioning is planned for spring 2018. Another minimill will be built in Bangladesh for the production of completely different products: rebar and steel sections mainly for the construction industry. Here, GPH Ispat has opted for a revolutionary plant concept that not only allows virtually uninterrupted casting and rolling of long products, but also reduces investment and operating costs. In this project, the new “WinLink Flex” concept will be implemented for the first time worldwide. Also the other articles in this issue illustrate how steel companies prepare for the challenges of global oversupply and increasingly stronger environmental regulation. Everywhere there is a firm belief that countries need state-of-the-art steel products today and in the future.

The extensive overhaul was concluded in October 2016 by bringing the facility into its test run-up. The facility is fully operational now and set to work for the next 20 years at least. â&#x20AC;&#x153;This was one of the ironworksâ&#x20AC;&#x2122; most significant investments in technology improvement in recent years,â&#x20AC;&#x153; said JĂĄn Moder, first vice chairman of the supervisory board. The coke-oven battery No. 11 was shut down on 14 September 2015 â&#x20AC;&#x201C; 23 years after the previous general overhaul. The main part of the modernization was the new lining of the coke-oven battery and its 72 cokeovens (chambers), using 10,000 t of refractory material. â&#x20AC;&#x153;During this project, we replaced the operational facilities with new technology, including the installation of new coke-oven machines. Accordingly, the new battery fulfills all requirements of best available technology (BAT) and operates strictly within the applicable environmental thresholds,â&#x20AC;? said Jan Czudek, CEO of Trinec Iron and Steel Works. Applying the new technologies will contribute to a further reduction of emissions. The upgraded battery is equipped with an exhaust system. Therefore gas resulting from the contact between the coal and the hot chamber is captured and purified. Coke gas is used as fuel and re-used in coke production together with the blast furnace gas.

Voestalpine is continuing to systematically drive forward its expansion in the NAFTA region. In accordance with Group Strategy 2020, it is intended to increase revenue generated in this region from its current level of EUR 1.2 billion (~ USD 1.4 billion) to EUR 3 billion (~ USD 3.4 billion) by the business year 2020/21. “Today’s opening of the direct reduction plant in
Corpus Christi is an important step for – and into – the future of our company. The new plant will not only secure the Austrian Voestalpine sites by supplying premium pre-materials for steel production, it will also contribute significantly to further strengthening our position in the NAFTA region. Furthermore, over the long term it offers us new technolog-
IRONMAKING ical options for decarbonizing steel production,” says Wolfgang Eder, chairman of the management board of Voestalpine AG. From the business year 2017/18 onwards, Voestalpine Texas LLC, a company in the Steel division of the Voestalpine Group, will use natural gas to produce two million tonnes of premium HBI (hot briquetted iron: porous sponge iron, pressed into briquettes) each year, 40 percent of which (800,000 tonnes) will cover internal requirements. The remaining 60 percent of the production volume goes to external partners, with the corresponding offtake agreements already having ensured full capacity utilization for the next four years.
In contrast to the pure coke- and coalbased blast furnace route, the plant in Corpus Christi uses only comparatively environmentally friendly natural gas as the reducing agent. Across the group, using the HBI produced in Texas in Voestalpine blast furnaces and steel plants will lead to a reduction in CO2 emissions of around 5 percent. At the same time, the new plant opens up further technological possibilities for the future. “We are systematically working to gradually decarbonize steel production, first by the partial substitution of coal and coke with gas-based bridging technologies, and then by the long-term, gradual use of CO2-neutral hydrogen.

ments for the project location, particularly the necessary port facilities. The plant’s own deep-sea port can currently handle 5 million tonnes of material each year (3 million tonnes of iron ore pellets and 2 million tonnes of HBI). The 137-metre-high reduction tower forms the heart of the plant and is the highest building in southern Texas. Voestalpine Texas LLC is creating 190 new jobs at the plant, and will generate value in the region to the sum of
around USD 600 million over the coming decade.
Locational advantages in the USA A politically stable and predictable environment, professional cooperation with the authorities, cost-efficient energy supply and logistical advantages were the key reasons behind the decision to locate the plant in Corpus Christi. “As an
investor, during each phase of the project we were able to notice the intense efforts being made to reindustrialize in the USA. The USA has recognized that a sustainable industrial manufacturing base is essential to a country’s stable economic development over the long term,” says Wolfgang Eder. Compared to the USA, Austria and Europe will doubtless remain an expensive location in the long run, particularly in terms of energy supply: average industrial gas prices in Austria over the longer term are around three times as high, and electricity prices around twice as high as those in the USA. The annual costs of operating an identical direct reduction plant in Austria would be around EUR 200 million (~ USD 225 million) higher than in Texas, purely due to the price differences for gas, electricity, and logistics. “In Europe, however, increasing political and social detachment from anything to do with industry is at least equally problematic,” Eder concludes.

››› RAW MATERIALS
Conversion of automotive shredder residues and use of synthetic carbon as chemical energy in the EAF Danieli has developed a competitive route able to recycle and valorize automotive shredder residue (ASR) components. The plant consists of two parts: one dedicated to the recovery of ferrous and non-ferrous metals and one for the production of synthetic carbon (SYNCA) from the clean plastic mixture. SYNCA is an optimum feed material for the EAF serving as partial substitution for the metallurgical carbon. In the recent past, major steelmakers have been reassessing waste materials (such as the EAF and LF slags) to turn them into value and avoid disposal costs. This trend has meanwhile also become a legal obligation. The same applies to the treatment of automotive shredder residues (ASR) from the shredding of end-of-life vehicles (ELV). Obviously, the scrap (i.e. 75 – 80% of the ELV) is a highly valuable EAF charge material. But also the remaining approximately 20 – 25% of the residues – ASR or fluff – are reused. ASR contains a mixture of plastics, rubber, paper, textiles, wood, as well as metals (ferrous and non-ferrous). Up until a few years ago the commonly accepted destination for ASR was the landfill, and this non-virtuous route is still in operation in many countries, but the rules have been changing rapidly. In Europe, the Directive 2000/53/EC has been in force since January 2015, establishing that vehicles are: ▪ reusable and/or recyclable to a minimum of 85% by weight per vehicle, ▪ reusable and/or recoverable to a minimum of 95% by weight per vehicle. Only a maximum 5% per vehicle may be sent to disposal. To understand the variability in the composition of ASR, it is necessary to know that it contains many different plastic components, rubbers and synthetic textiles.

Sorting plant layout
The main components, i.e. metals, inerts and plastic fractions, have different chemical characteristics and calorific values. Typically, there is a metals content of approx. 10% and an inerts content of approx. 5%. The remaining fuel/reductant fraction (85%) is split into: ▪ heavy fraction (PP, PE, PVC, PET etc.), 35 – 45% w/w, 28 – 35 MJ/kg ▪ light fraction (PU, rubber, paper, textiles, wood), 35 – 45% w/w, 15 – 20 MJ/kg. The patented solution developed by Danieli allows the quantitative recovery of the metals (ferrous and non-ferrous) and the treatment of the rubber/ plastic/textile fraction for recovery in EAF steelmaking. Its high calorific val-
ue and its reductant capacity are taken advantage of in the EAF as partial substitution of the carbon so that it can be considered as “synthetic carbon”. The two fractions of synthetic carbon as described above (i.e. light and heavy fractions) are dependent on the densities of the mixtures. Danieli performed a comprehensive campaign of tests to optimize the steps for ASR treatments and to obtain a flexible layout of a plant for the ASR treatment and recycling into the EAF.
Metals recovery Various processes and technologies are applied to the ASR as pre-treatments, such as:
RAW MATERIALS ▪ grinding, ▪ air sorter – for the separation of the light plastic fraction, ▪ sorting table – for the separation of the heavy plastic fraction and metals, ▪ eddy current sensors – for the recovery of the non-ferrous metals (mainly Al and Cu), ▪ magnetic separators – for the recovery of the ferrous content. By these sorting steps, the following ASR components are obtained, followed by the preparation of “synthetic carbon”: ▪ mixed ferrous fraction, ▪ aluminium-rich fraction, ▪ copper-rich fraction, ▪ light plastic fraction after briquetting, ▪ granulated briquettes, ▪ heavy plastic fraction after granulation. Generally, the recovery of 10% of the ASR as metals is possible. The metal mixtures are marketable as Zorba (predominately aluminium), Zebra (brass, copper, zinc) and Zurik (predominately stainless steel) or can be further refined by additional steps to increase their values, depending on the customer’s request.
Light and heavy plastic fractions – characteristics and treatment Various conclusions can be drawn from the thermogravimetric characterization of the two (light and heavy) plastic fractions. First, the light fraction leaves a bigger amount of ash after oxidation, in comparison to the heavy fraction. Second, the velocity of thermal decomposition in Ar of the light fraction is lower than that of the heavy fraction and anthracite. The anthracite is used as reference for the conventional EAF utilization. The velocity in the temperature range of 450 – 550°C is: ▪ 3.2%/minute weight loss for the heavy fraction, ▪ 1.4%/minute weight loss for the light fraction, ▪ 0.6%/minute weight loss for anthracite (reference). Finally, unlike the anthracite, the weight of which decreases only slightly during the thermal treatment in inert gas, the plastic mixtures react with the same mechanism in both air and inert gas treatments. In brief: whereas

the anthracite reacts in air producing CO/CO2, but does not react in inert gas, the plastic mixtures react in both inert gas and air to CnHm. The rate of the decomposition and the gas emissions represent the most important issues for the utilization of these materials inside the EAF. As a matter of fact, the developed gases allow foaming gas generation and deliver the rate of decomposition to keep the foaming slag stable. This provides for a significant saving of electrical energy inside the EAF because the loss of energy due to arc radiation is reduced. A sequence of melting tests was performed using a 40 kg vacuum induction furnace (VIM). The tests demonstrated the fast reactivity of the synthetic carbon (SYNCA) fractions. Moreover, the analysis performed on the products verified an average steel carburization potential of these mixtures amounting to 30%, with the material being directly fed into the liquid steel. The main part of the components leaves the steel bath as gases, improving foaming slag generation. The two plastic mixtures have attractive calorific values (LCV: 18MJ/ kg ÷ 32MJ/kg). Feeding them into the EAF as partial substitution of the carbon is the best route for their valorization. The light fraction of the ASR is the plastic material having the lowest density, such as polyurethane foam, textile etc. A dedicated device has been adopted to make this material dens-
er. Extruding this fraction, without any addition of agents, into briquettes provides much more flexibility for injecting the material into the EAF. The briquettes can either be filled into the basket or granulated for pneumatic transport. The heavy fraction comes from the grinding of the high-density plastic fractions containing PET, PE, PC, PVC, etc. Feeding this fraction into the EAF is easy: only a grinding treatment is required to obtain a grain size distribution close to that of the carbon injected by pneumatic transport.
Utilization of synthetic carbon (SYNCA) in the EAF The melting tests performed while feeding SYNCA fractions into the EAF demonstrated the high reactivity of this material as well as its potential for generating gases and foamy slag with the consequent positive effect on electric energy consumption. Depending on the percentage of carbon substitution (10 – 30%) savings of electrical energy were in the range of 2.3 and 8.5 kWh/t of liquid steel. Consequently, per t of liquid steel 1.8 to 5.4 kg of metallurgical carbon (substituted by SYNCA) are saved. Furnace productivity improves due to better operative conditions inside the furnace. This results in shorter operative time and a consequent increase in productivity in the range of 0.03 – 0.1 t/min. MPT International 1 / 2017

GPH Ispat Ltd. is a manufacturer of long steel products based in Chittagong in southeast Bangladesh. It produces rebars and profile steels, and has a current annual production capacity of 168,000 t of billets and 150,000 t of finished products. The company has
commissioned Primetals Technologies to supply a minimill with a total annual capacity of 815,000 t of finished products and billets. The new minimill will allow the company to substantially increase its capacities, and become one of the country’s leading producers,
HOT ROLLING serving the growing domestic and export markets. The new minimill meltshop is scheduled to come into operation early 2018. The order awarded to Primetal Technologies includes production facilities as follows: ▪ an EAF Quantum electric arc furnace, ▪ a ladle furnace, ▪ a three-strand, high-speed continuous billet caster, and ▪ a bar and section mill. WinLink Flex from Primetals Technologies will be installed for the first time worldwide. This concept not only allows virtually uninterrupted casting and rolling of long products, but also reduces investment and operating costs. Primetals Technologies will engineer and supply the processing equipment for the complete minimill meltshop. An EAF Quantum electric arc furnace with a tapping weight of 80 t and a tap-to-tap time of 40 minutes will produce steel at a rate of up to 36 heats per day. The EAF Quantum cuts operating costs with energy consumption figures as low as 290 kilowatt hours per metric ton. A special automation solution will be implemented so that the electric arc furnace can be charged with various combinations of diverse mixtures of scrap metal, or with DRI and HBI. Steel refining is performed in an 80-t ladle furnace with a heating rate of 4°C per minute. The three-strand continuous billet caster has a machine radius of ten metres, and casts round billets with diameters of 130 and 180 millimetres at casting speed up to 6 metres per minute. Nominal production capacity of the CCM is around 815,000 t per annum.
Induction billet heating technology The caster is directly connected to the downstream rolling mill. The high casting speed of up to six metres per minute and the compact size of the WinLink design allow two of the three strands to feed the downstream rolling line almost continuously. This has become possible because the usual reheating furnace has been eliminated; instead, the temperature of the billets is uniformly equalized for rolling in a compact, powerful induction furnace. Such plant configuration again is reducing investment and operating costs.
The third strand produces billets for subsequent further processing or for sale on the market. However, the bar and section mill has an annual production capacity of 640,000 t at a maximum production rate of 120 t per hour and a rolling speed of up to 27 metres per second. The rolling line has 20 fifth-generation Red Ring stands, including horizontal, vertical, convertible and universal stands. If required, the line can be run in two-slit rolling mode. The scope of supply also includes a system for rapid stand change, water cooling, a system for transferring steel bars at speeds

up to 27 metres per second to the cooling bed, which is 78 metres long and 11.2 metres wide, and a multi-strand stretch leveler. Primetals Technologies will also supply hot shears for cropping and dividing, a cold shear, a disk for cutting steel sections, a machine for counting rounds, mechanical and magnetic solutions for stacking and bundling finished products, and a banding station. In addition, there is secondary plant equipment, such as a mill workshop and laboratory, hydraulic and lubrication systems, special mechatronic packages, low-voltage supply, motors and drives, an uninterruptible power supply (UPS), as well as basic automation (level 1) and process automation (level 2). Primetals Technologies
will also be responsible for supervising installation and commissioning work.
Conclusion Primetals Technologies will supply a sophisticated minimill with an annual production capacity of 815,000 t of both, rolled long products and cast billets. The meltshop will be equipped with a highly energy efficient EAF Quantum. As a world premiere, the rolling mill will feature WinLink Flex technology to enable virtually uninterrupted casting and rolling of long products. All these technological solutions will substantially reduce conversion costs. GPH Ispat is set to become one of the country’s leading steel producers. MPT International 1 / 2017

FAICO is based in Sari, the provincial capital of Mazandaran, located in the north of Iran, only a few kilometres from the southern coast of the Caspian Sea, where FAICO has easy access to both domestic and international markets. The companyâ&#x20AC;&#x2122;s production units are equipped with state-of-the-art technologies in order to ensure consistency in quality; each stage of production
is computer controlled. FAICO operates two hot rolling plants, i.e. a rebar mill and a section mill, with a product mix ranging from dia. 8 mm to 32 mm for rebars (plain and ribbed) and various types of steel sections in heights from 100 mm to 320 mm. The products meet pre-determined specifications and are approved to be in compliance with national and international standards.
HOT ROLLING New section mill incorporating state-of-the-art housingless breakdown mill stands FAICO has ordered a continuous section mill with a design capacity of 500.000 t/year from MWE Magdeburger Walzwerk Engineering GmbH, Germany. The project was implemented in collaboration with the Turkish company CTS in Izmir. MWE delivered the complete design of the rolling mill. The plant was commissioned in May 2016. The rolling mill produces angles up to 150 mm, I-beams and channels up to 300 mm and H-beams up to 160 mm. One highlight of the rolling mill is the reversible and shiftable breakdown (BD) mill stand (dia. 850 mm, width 2,200 mm) to roll the billets (max. dimension: 280 mm x 220 mm, length: 6,000 mm) in a maximum of seven passes to a prefinished dimension suited to feed the downstream ten-stand continuous rolling line with quick stand-changing system. The rolls are driven by two 1,500 kW AC motors via a reducing and pinion gearbox and articulated spindles, transmitting a rolling torque of up to 1,800 kNm.
The new generation of MWE housingless BD mill stands allows high-efficiency bloom and ingot rolling in a full automatic mode. The installed equipment is approx. 50% lighter compared to conventional BD mill stands. Billet handling is performed in passline. Groove changing is carried out by stand shifting. Highly dynamic stand shifting is made possible due to the light-weight design of the housingless technology. Roll changing is followed by the changing of roll units with a shop crane within 30 minutes. Further types of similar mill stands are available with roll diameters of up to 1,600 mm. The process equipment includes two hydraulically actuated tilting devices in passline upstream and downstream of the mill stand. Tilting, stand shifting and billet handling is fully automated. No manual handling is needed. In the MWE BD mill stands full use is made of the advantages of the renowned housingless technology: â&#x2013;Ş high rate of rigidity both in the axial and radial directions, thus produc-

New coil handling technology improves quality Apart from occupational safety, a high degree of automation, more flexibility in production and customer service are central elements in coil handling. Therefore it is crucial that the entire process parameters are electronically documented and the material flow is traceable at all times. Intelligent data analysis supports conceptual freedom in bespoke development projects – especially when it comes to configuring product properties to meet specific requirements and the needs of individual customers. Swiss Steel has taken a crucial step towards Industry 4.0 in steel production. A new coil logistics system has been implemented downstream of the rolling mill. At the mill outlet, the wire rod bundles are transported by means of a vertical pallet system with 60 places and a smaller, horizontal hook conveyor to the state-of-the-art coil compactor press. The new handling technology has replaced the almost 40-year-old horizontal hook conveyor system.
Combined with the new coil compactor, the process is now faster and safer and ensures consistent quality while using much less energy. At the end, the loose wire is pressed into compact coils using two press plates to prevent damage to the product. The pressing power of this process can be adjusted as required. The coils are then bound with steel strips to obtain an even more compact package. Contrary to conventional binding with steel wire, binding with steel strips guarantees transport safety and surface quality at all times. Swiss Steel can now offer additional benefits to the customer in terms of higher efficiency during the initial wire processing step. The company is thus optimally prepared to cater to the increasing demand for higher coil weights and enhanced wire processing technologies. Swiss Steel modernized the wire rod coil handling technology during the production stoppage of summer 2016, together with the modernization of the Kocks block commissioned in 2002. In taking this step, supply reliability has increased substantially, while maintaining the highest quality standards. Occupational safety has also improved, now complying with the highest of health and safety regulations.
Conclusion There is a growing trend toward special steel products with customized characteristics. By investing in a new, fully automatic coil handling system at the wire rod mill, Swiss Steel has taken an important step towards implementing Industry 4.0 in steel production. The recent investments are important prerequisites for developing and marketing customized steel products. By modernization Swiss Steel AG is further strengthening their technology leadership position.

â&#x20AC;şâ&#x20AC;şâ&#x20AC;ş SPECIAL EQUIPMENT
Risk assessment and safe installations can make the mill a safer and more productive workplace A proper risk assessment can help identify and remedy vulnerabilities in an equipment control system. In the future, safety will have an increasingly interactive role in Industry 4.0. ROSS Controls is at the forefront of this revolution as they constantly develop new valve technology to push the safety curve higher. Like most steel mills: the goal is zero harm. ROSS valves and air preparation units are recognized around the world for their reliability, repeatability, and robust design. Wherever in the world a mill project is located, ROSSâ&#x20AC;&#x2122; global network of steel industry pneumatic experts, manufacturing facilities and distributors can help keep the mill running smoothly and productively and, what is more, they can help to define pneumatic control needs throughout the mill and develop turnkey pneumatic panels and stands ready for connection to the mill equipment. ROSSâ&#x20AC;&#x2122; capabilities include panel/stand circuit design, mechanical arrangement, manufacture, testing, follow-up training as well as local service. Of course, ROSS industry experts focus on â&#x20AC;&#x17E;Safety in the steel industryâ&#x20AC;&#x153;, too, knowing from experience and interaction with industry specialists that the implementation of safety-related concepts is not only required by law (i.e. Machinery Directive 2006/42/EG), but economically reasonable, too.
Improving safety does not compete with productivity CPF RTQĆ&#x201A;VCDKNKV[ IQCNU The economic climate places production optimization as a top priority for all steel mills. At the same time, safety is fully addressed and with an equal sense of urgency. A proper risk assessment can help identify and remedy vulnerabilities in an equipment control system.
When properly implemented, a risk reduction program can correct process inefficiencies, prevent serious accidents and their related equipment downtime, personnel injuries, legal actions, increases in workersâ&#x20AC;&#x2122; compensation premiums, as well as improve environmental concerns.

SPECIAL EQUIPMENT prove productivity and ultimately increase the bottom-line. However, risk is subjective; risk is perception. In other words, one person’s idea of risk can be different from another person, thus the level of acceptable risk can vary. One way to mitigate such variability is by instituting objective risk assessment protocols and models.
2TQHGUUKQPCN TKUM CUUGUUOGPV Risk assessment is divided into two phases: ▪ risk anlaysis and ▪ risk reduction. Risk analysis is a process by which the intended use of the machine (and foreseeable misuse), the tasks and hazards, and the level of risk are determined. Risk reduction is the process of choosing and applying methods for mitigating hazards and hazardous situations identified during the risk analysis. The appropriate documentation within the ISO, EN, ANSI, CSA and OSHA safety standards contains detailed information on risk assessment models. There are also risk assessment professionals that can be brought into the steel mill to conduct risk seminars and assist the workforce in making the mill a safer and more productive workplace. When in doubt, engineer it out. The above risk assessment process will identify areas of concern that may be eliminated by simply removing the hazard
altogether. For the most part, all mills have well documented procedures for lockout/tagout (LOTO), but it is prudent to revisit these simple, but critical,activities from time to time. Listening to worker suggestions is a good place to start. One example of a seemingly benign device, but found predominantly throughout many mills, are ball valves used as energy isolation devices. Adequate training and constant awareness is needed when relying on the long bleed-down time associated with a ball valve’s small vent port. Depending on the volume of the circuit, it could take several minutes before a ball valve dissipates hazardous energy compared to a handful of seconds associated with a large exhaust capacity energy isolation device. A new frontier in the world of safety revolves around safeguarding during temporary stops. These are stops not included in the normal lockout/ tagout procedure. Mills need to keep production running, and international safety standards address this economic reality with alternative lockout measures. There may be applications that are safety protected with electrical door interlocks, light curtains, safety mats, limit switches or other devices that temporarily stop a machine or process, but care should be taken to understand the complete circuit and how these devices are connected. An example of a temporary stop controlled by an electrical interlock would be the

in-process inspection area on a galvanizing line. Safety does not end at the wire. Even if there is a dual channel electrical safety switch, the question must be asked; what does the wire control? If that wire is connected to a pneumatic valve that controls hazardous energy, then the pneumatic valve should be control reliable. What is a control reliable pneumatic valve? In basic terms, it is a redundant (dual) valve with status monitoring. Depending on the application, category 3 or category 4 protection may be needed. Piping two valves together in series, or in parallel, is not an acceptable substitute for the higher level of protection outlined in the various safety standards. In many cases, the solution may be as simple as installing a control reliable valve at the starting point (air entry) of the air circuit.
1WVNQQM Safety will have an increasingly interactive role in Industry 4.0. Pneumatic safety valves are getting smarter. Safety valves are already communicating with process control systems. Some valves even have internal diagnostics that signal the process control system when a potential valve failure may be approaching. New valve technology is constantly under development to push the safety curve higher. Like most steel mills: the goal is zero harm.

This new partnership will look at the potential synergies that exist between the manufacturing processes of these three energy intensive sectors, and how these synergies could be harnessed to reducing CO2 emissions. LCTPi is a set of programmes, gathering 150 global businesses and 70 partners under the auspices of the World Business Council for Sustainable Development, to accelerate the development of low-carbon technology solutions to stay below the 2°C ceiling. As a first step, and following preliminary research, the innovative partnership will produce a study to identify potential ways to valorize industrial off-gases and other by-products from their manufacturing processes to produce goods with a lower carbon footprint than through the fossil path. The study is aimed at bringing a fact-based overview of carbon and energy sources from industrial off-gases (first at a
European level), and evaluating the technical, environmental and economic feasibility of different Carbon Capture and Usage (CCU) pathways and their potential. The preliminary research already allowed identifying significant potential in selected trans-sector pathways. Deploying cross-sector carbon capture and reuse opportunities on an industrial scale – something that does not happen today – could reduce up to 3 GT/year or 7% of global anthropogenic CO2 emissions. Existing conversion technologies that could be deployed across the three sectors could utilize by-products in the off-gases to create building materials, organic chemicals and fuel. Increased availability and greater access to renewable energy sources would significantly boost net carbon reduction efforts by those three sectors, within a supportive legislative framework.

(MRODBSHNM NE RGHMX @MC L@SS RTQE@BDR QUALITY CONTROL Particularly in automotive production, perfect surfaces – whether matt or shiny – are imperative. Even the smallest of defects must be reliably recognized. With the reflectCONTROL Automation surface inspection system, Micro-Epsilon offers a robot-guided system that projects a striped pattern onto the measurement object. Defects on the shiny surface cause deviations from the striped pattern which are recorded by cameras and evaluated by software. The compact deflectometry sensor, which consists of a monitor for the striped pattern projection as well as up to two cameras, is guided over the measurement object by a robot. The defects found are evaluated and displayed in a 3D model. For inspection tasks on matt surfaces, INB Vision, a company belonging to the Micro-Epsilon group, has developed the surfaceCONTROL system. It comprises a modern 3D sensor and the software for the data analysis. This new 3D sen-

a complete cleaning cycle. In contrast, Acoustic Expert from Primetals Technologies facilitates a condition-based maintenance strategy. To this end, a microphone as an acoustic sensor is installed in the penthouse of the plant MPT International 1 / 2017
to continuously monitor the noises in the environment. When the pulse-jet valves are activated, the sound spectrum they emit is recorded for several seconds. The recording is then analyzed in detail, and a report is generated to indicate whether or not the monitored equipment is functioning properly. The recorded data are then deleted. Acoustic Expert produces such a stable analysis that it is not impaired by background noises, and provides information about the current condition of each pulse-jet valve. The maintenance personnel receive direct information about which valves are working correctly and which need to be repaired. This reduces the cost of maintenance to the essential minimum. Acoustic Expert was designed on a bionic basis. All sounds perceptible to the human ear are monitored continuously. Whereas people find it difficult to detect gradual wear, Acoustic Expert makes this possible by long-term analysis. Acoustic Expert can also be used on all equipment that emits a specific sound spectrum, such as the nozzles of torch cutting machines in continuous casting plants, switching relays, and leaks in valve stations. Recently, an Acoustic Expert system was implemented at the secondary dedusting plant 3.1. of Voestalpine Stahl in Linz, Austria. The new system was installed in one day without any plant stoppages, optimized in just two days, and brought into operation two months before the scheduled date. Contact: www.primetals.com
“How can advanced lubricants help to improve safety at our steel mill?” Safety is a fundamental concern and the number one priority for operators in the primary metals sector. By extending equipment and components life advanced lubricants can help contribute to reducing employees’ exposure to hazardous maintenance procedures.
resulting in poor lubrication. As a result, mill operators were forced to decrease lubrication intervals, putting employees in contact with machinery more frequently. There was also the additional risk to employees of leaked grease making the floor slippery.
Procedures carried out during both scheduled and unscheduled downtime have an inherent safety risk to employees. By reducing the contact with machinery, this risk is cut. High-quality lubricants, particularly synthetic lubricants, can help extend oil drain intervals, reducing the frequency of scheduled maintenance. They also help to protect machinery, reducing the likelihood of equipment repairs.
We recommended switching to Mobilgrease XHP™ 222 which has excellent high temperature performance and structural stability. This change resulted in multiple benefits including extended oil drain intervals, therefore decreasing the frequency of employee interaction with machinery. It also reduced leakage, making the workplace cleaner with reduced risk for slips.
In an Italian steel mill, we worked with operators to help improve on-site safety. Extreme operating temperatures and loads were softening the grease used on bearings

Metallurgy Peculiarities in crystal structure of titanium alloys pave the way for new applications Metals which can be bent as gum pave the way for new industrial applications, for example in the aerospace industry. These so-called gum metals exist but the mechanism behind this behaviour was still unsettled and thus difficult to be used for applications. Scientists from Germany have observed a new phase transformation within the crystal structure in a titanium alloy. The advancement in knowledge actually helps to understand the behaviour of the gum metals.
Surface treatment ArcelorMittal inaugurates world-first Jet Vapor Deposition line for the steel industry ArcelorMittal has opened a new production line – the Jet Vapor Deposition (JVD) line – at its facilities in Kessales, Belgium. The JVD technology coats moving strips of steel in a vacuum chamber, by vaporizing zinc onto the steel at high speed. The JVD technology, which will be used to produce coated steels for automotive and other industrial applications, offers multiple advantages. Coating the steel under vacuum and at lower temperatures removes the risk of the steel or zinc oxidizing.
