1A Manufacturing Process for Iron and Steel

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.
