GEM wiki

ArcelorMittal Tubarão 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 7.5 million tonnes per year. Its main products are galvanized, slab, coil, cold rolled.
