Slag Foaming in an Electric Arc Furnace

Slag foaming in an electric arc furnace (EAF) is examined using a mathematical model of the EAF to com-pute the CO generation rate and slag chemistry and laboratory measurements of the foam index. The foam height limited by either the foam stability or from the amount of slag present was computed for a high pro-ductivity furnace using relatively large amounts of pig iron, carbon and oxygen.
