摘　　要：转炉出钢结束后向钢包内加入钢渣改质剂,可以降低炉渣氧化性(∑(FeO+MnO)的含量),提高转炉出钢脱硫效率。酒钢宏兴股份公司碳钢薄板厂在120吨转炉出钢后加入钢渣改质剂,研究出钢后加入钢渣改质剂对钢水质量、脱硫能力的影响。试验结果表明,出钢后加入钢渣改质剂,降低了炉渣氧化性,提高了脱硫效率,改善了钢水质量。After tapping of the converter, the steel slag modifier is added into the ladle,which can reduce the oxidizing property of the slag(the content of ∑(FeO+MnO)) and improve the desulfurization efficiency of the converter. After tapping of 120-ton converter in Carbon Steel Sheeet Plant of JISCO, the steel slag modifier were added into ladle to study the effect of steel slag modifier on the quality of the molten steel and the desulfurization capacity. The test results show that the steel slag modifier is added after tapping, which reduces the oxidization of the slag,improves the desulfurization efficiency, and improves the quality of the molten steel.
