The first step in the steel manufacture begins at the blast furnace. To separate iron from iron ore coke (substance when gas is taken out of coal), limestone and dolomite are charged into the blast furnace. Temperature raised to 1600oF. This high temp causes the coke to burn and melt the iron. This red hot iron drained at an opening at the base of the furnace.
