METHOD FOR CONTINUOUS CASTING OF MOLTEN STEEL FOR THIN SHEET |
摘要 |
Disclosed is a method of continuous casting of aluminum-killed steel, using a refractory martial containing 20 mass% or more of CaO . MgO-based clinker. 60% or more of MgO grains included in the grains of the CaO . MgO-based clinker have a diameter of 50 mu m or less. The refractory martial is used at least at a portion to be in contact with molten steel. The present invention can reduce the diameter of MgO grains as inclusions in slabs to suppress the occurrence of flaws in a milled sheet metal. <IMAGE> |
