Conclusions Converter slags formed in the first 10–12 min of the blowing of the iron, after cooling consist mainly of manganese-iron monticellite, glassy, and cryptocrystalline substances, free calcium oxide, and metallic iron. The primary slags are characterized by a low basicity, refractoriness, and viscosity, and rapidly react with the refractory during the period of their formation in the converter at 1150–1360°C. The primary slags are changed into the truly liquid state at 1256–1312°C. |
