ArcelorMittal completed the acquisition of Essar Steel India Ltd. (ESIL) and simultaneously established a joint venture with Nippon Steel Corp. called ArcelorMittal Nippon Steel India Ltd. (AM/NS India), which will own and operate ESIL. ArcelorMittal holds 60% of AM/NS India with Nippon Steel holding the balance. AM/NS India is an integrated flat-steel producer, including steel plates and steel pipes, with a current level of crude steel production of 7.5 million metric tons per year. It also has iron-ore pellet facilities in eastern India, with current annual capacity of 14 million metric tons.
Cleveland-Cliffs Inc. and AK Steel, a leading producer of flat-rolled carbon, stainless and electrical steel products, entered into a definitive merger agreement pursuant to which Cliffs will acquire all of the issued and outstanding shares of AK Steel common stock. The transaction will combine Cliffs, North America’s largest producer of iron ore pellets, with AK Steel to create a vertically integrated producer of value-added iron ore and steel products. The combined company will be ideally positioned to provide high-value iron ore and steel solutions to customers primarily across North America.
A rolling-mill expansion at Steel Dynamics’ facility in Columbia City, Ind., includes a new billet welder and an induction furnace. The billet welder and spooler line will produce spooled coils up to 5 tons. The 3-MW induction furnace will heat the stock coming from the existing mill. The expansion also includes a 70-meter conveyor connecting the existing medium section mill to the new spooler line, six housingless roller stands complete with quick stand-changing table, a six-pass Delta-type finishing block driven by a low-voltage 2.5-MW motor and finishing services.
Germany’s Salzgitter Flachstahl GmbH awarded a contract to build a 2.2-MW proton exchange membrane (PEM) electrolysis plant to Siemens Gas and Power, marking an important step toward hydrogen-based steelmaking. The plant is due to commence operation in the fourth quarter of 2020 and will cover Salzgitter’s entire current demand for hydrogen. The necessary electrical power will be generated by seven wind turbines.
United States Steel Corp. plans to reduce greenhouse-gas-emissions intensity across its global footprint by 20%, as measured by the rate of carbon dioxide (CO2) equivalents emitted per ton of finished steel shipped, by 2030 based on 2018 baseline levels. This target will apply to U.S. Steel’s global operations. The company plans to achieve this goal through multiple initiatives, including the development of electric-arc furnace (EAF) steelmaking at its Fairfield Works and at Big River Steel, in which U.S. Steel recently acquired a minority interest with an option to acquire the remainder over the next four years.
Acerinox S.A., a stainless steel manufacturer based in Spain, acquired Germany’s VDM Metals Holding GmbH, a producer of specialty alloys, for approximately $585 million. The deal will allow Acerinox to diversify into growing markets such as aerospace, medical and oil and gas. VDM Metals develops and manufactures nickel, cobalt and zirconium alloys. The company also supplies sheets, strips, bars, rods, wires and welding fillers. Acerinox operates six manufacturing facilities on four continents and has an annual melting output of 3.5 million metric tons.
Process metallurgists (like me) use math, physics and chemistry to describe what happens during metal manufacturing. Other researchers use math, statistics and computer science to study and optimize manufacturing at a larger scale.
Nucor Corp. selected SMS group for the supply of a single-strand continuous caster for ultra-wide and thick slabs. Designed for an annual capacity of 1.45 million tons, it will be a core element of the production chain of Nucor’s new plate mill in Brandenburg, Ky. The companies say the casting machine will be one of the largest of its kind worldwide. The caster will produce slabs 8-12 inches (200-305 mm) thick up to 124 inches (3,150 mm) wide. Slab lengths will vary from 104 to 600 inches (2,642 to 15,240 mm).
Andritz received an order from Steel Dynamics Inc. for the supply of key process equipment for the existing continuous galvanizing line (CGL) at its Columbus, Miss., plant. The scope of supply includes engineering and delivery of a new direct-fired furnace, differential rapid jet cooling and after pot coolers. The project will be implemented during the fourth quarter of 2020. Andritz will also supply the model-predictive advanced furnace control for the complete furnace sections as well as the automation and electrical equipment.
Researchers at Carnegie Mellon University’s (CMU) Center for Iron and Steelmaking Research are bringing computer-vision and machine-learning techniques to the study of inclusions, hoping to increase the efficiency of inclusion analysis and gain new insights.
