Zusammenfassung:	PURPOSE:To prevent slopping of slag, rephosphorization into a molten iron and slag foaming at in the case of desiliconizing treatment in the molten iron. CONSTITUTION:Slag making agent consisting mainly of slag remaining in a molten steel ladle 12 after decarbonization and finishing dephosphorization to dephosphorized molten iron obtd. from a separately dephosphorizing process 9, in the decarbonizing furnace 2, is uesd. Slag basicity is limited to
