Steelmaking - Wikipedia

The calcium oxide acts as a chemical flux, removing impurities in the form of slag. For example, the calcium oxide can react to remove silicon oxide impurities: SiO 2 + CaO → CaSiO 3. This use of limestone to provide a flux occurs both in the blast furnace (to obtain pig iron) and in the basic oxygen steel making (to obtain steel). Hot blast
