The amount of carbon picked up by the iron is more than is needed in the production of steel. The carbon becomes part of the pig iron used in the making of steel. The control of this carbon during the subsequent processes determines the properties of the steel. The manufacture of coke from bituminous coal is a distillation process.

The smelting and refining process for iron and steel in the BF-BOF process involves the carbon reduction of iron ore (Fe 2 O 3) in the BF to make molten iron, and decarburization of molten iron in the BOF to make molten steel. Major reducing agent in the BF is the carbon monoxide gas (CO) generated by the oxidation of the carbon (C) in coke.
