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.
Danieli has been selected to supply equipment for Nucor’s new greenfield plate steel mill in Brandenburg, Ky. Danieli will supply an electric-arc furnace (EAF) melt shop and plate/steckel mill, as well as an electrical and automation package provided by Danieli Automation. The EAF will be equipped with all modern mechatronic devices to improve its performance and safety. Danieli will also supply secondary metallurgy equipment, including a twin-station LMF and a twin-station VTD equipped with mechanical pumps. Both units will include with the latest automation and process models to ensure precise chemistry and temperature control.
Danieli Olivotto Ferrè started up a tube roller-hearth annealing furnace at Tenaris Tamsa in Veracruz, Mexico. The furnace is designed to treat steel tubes coming from cold or hot processing with a maximum throughput of 5 tons/hour. It is able to perform different heat-treatment cycles, including normalizing, annealing, tempering and stress relieving. The pipe to be treated has an OD range from 15-120 mm, thickness from 1.5-20 mm and length up to 16 meters (52.5 feet).
Andritz received an order from North Star BlueScope Steel for supply of a tunnel furnace and two shuttle furnaces to convey the slabs from both casters to the two-stand roughing mill at its Delta, Ohio, plant. The shuttle furnaces will be installed during the fourth quarter of 2020, and the tunnel furnace is scheduled to start production by the end of 2021. This order is part of an expansion project by North Star BlueScope that will also add a third electric-arc furnace (EAF) and a second continuous caster. The expansion will increase the facility’s annual capacity by 800,000 to 900,000 metric tons.
Extractive metallurgy is an area of our science that deals with the process and methods of gathering and isolating metals from their ores (i.e., natural mineral deposits) and in some instances refining them.
Fives received two contracts to design and supply reheating furnaces to Chinese steelmakers, both with strict requirements on energy consumption and NOx emissions. The first project covers an ultra-low-NOx furnace to reheat long products, such as stainless steel bars, coils or wires, for Yantai Walsin Stainless Steel. Fives will supply a walking-beam furnace with a capacity of 85 tons per hour. The second contract was signed with Shijiazhuang Iron & Steel Company within China’s HBIS Group for two reheating furnaces, each with a production capacity of 130 tons per hour.
