The steel plant process flow document outlines the steps in manufacturing steel from raw materials to finished products. Iron ore, scrap metal, coal, and limestone are heated to high temperatures in a blast furnace to produce molten iron and slag. The molten iron and other alloys are further processed in a basic oxygen furnace to produce steel. The molten steel is then continuously cast into semi-finished steel products like slabs, billets, or blooms for further rolling and processing into finished steel products.
