Control of Slag and Insoluble Build-up in Melting Furnaces

Coreless Induction Furnaces: The coreless induction furnace is a refractory lined vessel with electrical current carrying coils that surround the refractory crucible. A metallic charge consisting of scrap, pig iron and ferroalloys typically are melted in this vessel. When electrical current from the coils is passed through the charge, a magnetic field is formed. The field creates thermal energy, which melts the charge. The magnetic currents in the molten metal cause an intense stirring action, thus ensuring a homogenous liquid. During the melting process, slag nonmetallics and insolubles are generated from oxidation products, dirt, sand, and other impurities from the scrap, erosion and wear of the refractory lining, oxidized ferroalloys, and other sources. Sometimes, the term "dross" is also used to describe these insoluble by-products of the melting process. These nonmetallics remain in the liquid metal as an emulsified slag …
