Steelmaking and Refining

The formation of slag, which floats on the surface of the molten steel, is an important part of steelmaking. Slag usually consists of metal oxides and acts as a destination for oxidized impurities. It functions as a thermal blanket, stopping excessive heat loss, and helping to reduce erosion of the refractory lining.
