Tenova Italimpianti received a contract for a 340-ton/hour walking-beam furnace from Jindal United Steel Limited (JUSL), a company that specializes in hot and cold rolling of stainless steels, in Jajpur, Odisha, India. The furnace is designed to charge stainless steel (grade series 200, 300 and 400) and low-carbon steel in order to comply with JUSL’s various production needs. The installed combustion system is designed to optimize performance (flame characteristics, efficiency and pollutant emissions) in function of the fuel and burner location (frontal, lateral or radiant application). The multi-level automation control system optimizes heating practices, regulating fuel consumption and scale production.
ArcelorMittal Belgium will reduce CO2 emissions by 3.9 million metric tons per year by 2030 by building a 2.5-million-metric-ton direct reduced iron (DRI) plant and two electric-arc furnaces (EAFs) at its Ghent site to operate alongside a blast furnace that is ready to take waste wood and plastics as a substitute for fossil carbon. A DRI plant uses natural gas, and potentially hydrogen, instead of coal to reduce iron ore, which results in a reduction in CO2 emissions compared with blast-furnace ironmaking. The two EAFs will melt the DRI and scrap steel, which will then be transformed into steel slabs and then further processed into finished products.
Primetals Technologies started up an electric-arc furnace (EAF) it supplied to specialty materials producer Allegheny Technologies Inc. (ATI) for its Latrobe, Pa., facility. The EAF, which is designed to process a wide range of input materials and will replace equipment coming to the end of its useful life, increases flexibility and reliability while reducing energy consumption and maintenance requirements. It is part of ATI’s transformation of its Specialty Rolled Products business, which serves customers in aerospace, defense and other highly demanding markets. Primetals Technologies engineered the EAF specifically for foundry applications. It is suitable for melting and refining. The project also included the hydraulics for furnace movement and automation systems.
Alcoa Corp. plans to restart 268,000 metric tons per year (mtpy) of aluminum capacity at its Alumar smelter in São Luís, Brazil. The facility has been fully curtailed since 2015. The process to restart will begin immediately. The first molten metal is expected in the second quarter of 2022, and the full 268,000 mtpy of capacity is expected to be operational in the fourth quarter of 2022. The Alumar smelter restart will involve the hiring of more than 750 employees.
Nucor Corp. announced that its board of directors approved the construction of a new melt shop at one of the company’s existing bar mills in the western United States. The new $100 million facility will have the capacity to produce 600,000 tons annually and create approximately 140 new full-time jobs. Start-up is expected in 2024. Nucor has 15 bar mills strategically located across the country that manufacture a range of steel products, including concrete reinforcing bars, hot-rolled bars, rounds, light shapes, structural angles, channels, wire rod and highway products in carbon and alloy steels. Four of the bar mills have a significant focus on manufacturing SBQ and wire-rod products.
Innovative Concept Opens Up New Casting Applications, Designs
September 21, 2021
Engineers have succeeded in building an industrial-scale levitation melting system. The special design allows casting of various reactive metals and alloys up to 500 g with high purity and short cycle times.
United States Steel Corp. announced an exploratory site selection process to build a new 3-million-ton flat-rolled minimill in the United States. The planned minimill will combine two state-of-the-art electric-arc furnaces (EAFs) with differentiated steelmaking and finishing technology, including purchased equipment already owned by the company. The continued adoption of minimill technology will expand U.S. Steel’s ability to produce the next generation of proprietary sustainable steel solutions, including advanced high-strength steels (AHSS). Potential locations include states in which the company has existing EAF operations and greenfield sites. The current estimated investment is approximately $3 billion.
SECO/VACUUM, a SECO/WARWICK Group brand, sold a vacuum aluminum brazing (VAB) furnace to an international aircraft component supplier. The furnace is designed to meet tight temperature tolerances of +/-3°C and incorporates a high-vacuum system with diffusion pump. The VAB furnace is equipped with six temperature control zones and can accommodate loads with dimensions up to 36 inches wide x 28 inches high x 48 inches deep (900 x 700 x 1,200 mm). Delivery is scheduled for early 2022.
Wall Colmonoy completed an upgrade to its casting facility in Pontardawe, Wales. The approximately $822,000 investment modernizes the company’s casting foundry, reducing its environmental footprint and improving its efficiency. The casting upgrade includes new induction melting equipment and magnetically screened furnaces. The furnaces offer increased capacity and reduced processing times.
