Steel Making Process
Steel ProductionAmerican Iron and Steel Institute
Coal is a key part of the coke making process The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen As the oven is heated the coal begins to melt so most of the volatile matter such as oil tar hydrogen nitrogen and sulfur are removed

Manufacture of SteelSteel Manufacturing Process and Steps
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
