Lime in the Steel Industry Graymont

Lime is used as a fluxing agent in electric arc furnaces and basic oxygen furnaces. Lime removes impurities (silica, phosphorus, sulfur) from the steel being manufactured. The lime fuses with the impurities to form slag, which separates from the steel and is removed. This process improves the quality of the steel.
