For foundries operating induction melting and pouring systems there has long been a negative association with the use of fluxes for ferrous metal production. Refractories commonly used in induction furnaces, such as silica-based linings, are very prone to chemical attack from fluxes. In many ferrous melt shops, mixtures of lime/fluorspar (CaCO3/CaF2) are commonly added, for desulphurization, phosphorus reduction, deoxidation, coke cleansing, or to improve metal cleanliness.  However, ...
