摘　　要：The MgO content in end blowing slag for large BOF at Bao Steel is controlled within 10%,about 100 kg/t,steel .The formed splashed layer is 20 mm-300 mm in thickness,possessing high refractoriness.The erosion to splashed layer usually takes place at the and of blowing when the temperature is high,The slag enters into the pores and cracks of MgO-C brick which lowers the melting poing of MgO particle.
