    Aug 23, 2016 Lime is a common chemical used in iron and steel manufacturing, acting as a flux in purifying steel in electric arc furnaces (EAF) and basic oxygen furnaces (BOF). In addition to removing impurities, calcium oxide reduces refractory wear and gunning, and can provide a foaming slag for long arc operation.
