Making Slag an overview | ScienceDirect Topics

· Steel slag is an industrial waste that is generated during the production of steel In the production of steel, oxides of metal impurities in the iron combine with the flux (which is usually a mixture of lime and dolomite) to form a molten layer of steel slag that floats on top of the steel The molten slag is later cooled and granulated Steel slag may also be referred to as steel furnace
