U.S. Steel Great Lakes
mothballedUnited States Steel Corp · BF–BOF Integrated route · Ecorse, North America, United States
U.S. Steel Great Lakes makes steel by the integrated route: iron ore is smelted into liquid hot metal in a blast furnace, then refined into crude steel in a basic oxygen furnace. The liquid steel is solidified into semi-finished shapes by continuous casting. The plant has a crude steel capacity of about 3.5 million tonnes per year. Its main products are sheet, coated.
