Algoma Selects Danieli for its EAF Technology

Algoma Steel Group Inc. has picked Danieli & C. Officine Meccaniche S.p.A (Danieli) as the technology provider for their new electric arc (EAF) steelmaking facility set for operation in early 2024.
The Sault Ste. Marie, Ontario-based steelmaker said that Danieli’s systems were the best choice for their new mill as they transition away from basic oxygen steelmaking.
The switch from BOF to EAF is expected to reduce Algoma’s CO2 emissions by roughly 70% and position them as one of North America’s leading providers of green steel, the company said.
The new green steel shop will have a design capacity of 3.7 million tons of liquid steel with two 250-ton EAFs at its core. The furnaces will be powered by two Q-One digital power systems with a rated capacity of more than 190 MVA each. Danieli’s patented Q-One technology improves energy efficiency and electrode consumption by continuously varying the electric frequency during each melting phase. Two new off-gas treatment plants including baghouses and a dedicated recirculating water treatment plant will combine to provide for emission control and filtration and water conservation, the steelmaker said.
The facility will have a completely automated scrap yard, including cranes, scrap recognition, sorting, and charging. A Danieli Twin-Tank Vacuum Degasser with an oxygen blowing facility will help deliver advanced grades of steel and further enhance steel cleanliness and final product quality, the company said.
The Canadian steelmaker is a fully integrated producer of hot and cold rolled steel products including sheet and plate. Current raw steel production capacity is estimated at 2.8 million tons per year, serving the automotive, construction, energy, defense and manufacturing sectors.
