4,7% carbon (C); 0,5% manganese (Mn); 0,4% silicon (Si); 0,1% phosphorus (P) and 0,04 % sulphur (S), the remainder being iron (Fe). Sulphur removal from the melt needs low oxygen activities. Desulphurization is therefore achieved in the hot metal by injection of calcium carbide fluxes to form calcium sulphide (CaS) or fluxes containing metallic ...
