What raw materials are required for steel making?

Pig iron is later processed, to form steel billets, by heating in arc furnaces. Iron ore serves as the primary raw material for manufacturing a wide range of steel products. Coal/coke: Bituminous coal is heated at 1000-2000 °C in a blast furnace, to drive off impurities, leaving nearly pure carbon. The furnace is blasted with a hot blast ofget price

Steelmaking Process an overview ScienceDirect Topics

During the steelmaking process, fluxes that consist of lime (CaO) or dolomitic lime, with iron and scraps, are charged to the furnace.There is a certain amount of free lime (f-CaO) in steel slag. Free lime, with a specific gravity of 3.34, can react with water to produce Ca(OH) 2, with a specific gravity of 2.23, which results in volume increase (Fig. 9.1).get price
