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.
Novelis Inc. broke ground on a $36 million investment to expand and upgrade recycling capacity at its Greensboro, Ga., facility. The project includes adding state-of-the-art equipment for aluminum scrap recycling, a new baghouse for improved dust mitigation and enhanced designs for safer and more efficient traffic flow. The company expects to complete the project by fall 2021. The investment will expand the company’s capabilities in automotive closed-loop recycling, a process to take aluminum scrap created during stamping and recycle it for new vehicle production. Closing the loop preserves the value of the alloy, reduces cost, minimizes environmental impact and establishes a secure supply chain.
Allegheny Technologies Inc. signed another one-year agreement to extend and expand carbon-steel hot-rolling conversion services for NLMK USA at its Hot-Rolling and Processing Facility (HRPF) in Brackenridge, Pa. The agreement provides NLMK USA with continued access to the HRPF’s capabilities for conversion of their broad range of carbon-steel grades through December 2020. ATI’s HRPF enables production of materials that maintain high strengths at high temperatures. It allows control and tailoring of sheet and plate microstructures and other physical attributes to meet specific performance requirements at shorter cycle times in wider sizes with efficiency.
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.
Solar Manufacturing shipped a vacuum furnace for processing additively manufactured parts to a large science and technology laboratory. The lab requires the furnace, which has a maximum temperature of 2400°F (1315°C), to further their research and development work. Built with Solar Manufacturing’s SolarVac Polaris control system and a graphite-insulated hot zone, the furnace is designed to accommodate loads up to 36 inches wide x 36 inches high x 48 inches deep with a maximum weight of 5,000 pounds.
Gardner Aerospace, one of Europe’s leading suppliers of aircraft parts and sub-assemblies, invested in a high-pressure fluid-cell press from Sweden’s Quintus Technologies. Gardner recently opened a 45,000-square-meter manufacturing facility in Chengdu, China, that will support China’s rapidly developing domestic market for aerospace parts. The 800-bar (11,600-psi) press has a forming area of 700 mm x 1,800 mm (27.6 x 73 inches). Gardner purchased a high-pressure fluid-cell press from Quintus in 2015. It has a central position at the company’s facility in southern France, where it has generated significant cost savings and eliminated several forming operations.
Spirit AeroSystems Holdings Inc. entered into a definitive agreement to acquire select assets of Bombardier aerostructures and aftermarket services businesses in Belfast, Northern Ireland (known as Short Brothers); Casablanca, Morocco; and Dallas, Texas. The acquired Bombardier operations employ more than 4,000 people at three sites comprising approximately 3.4 million square feet. The backlog of work includes long-term contracts on the Airbus A220 and A320neo, along with Bombardier business and regional jets.
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.
L&L Special Furnace Co. Inc. shipped a floor-standing box furnace to a high-tech aerospace and associated components manufacturer located in the southeastern U.S. The furnace, which has a work zone measuring 120 inches wide x 48 inches high x 72 inches deep, will be used for processing aerospace parts and various thermal applications. It has a temperature gradient of ±20°F from 1100-2150°F using eight zones of temperature control with biasing to balance any differential in temperature gradients.
