摘　　要：结合承德钢厂转炉半钢特性,在100t钢包中使用侧吹氧枪和底吹氩气进行工业脱磷试验。试验表明,大供氧流量条件有利于提高炉渣的脱磷能力;脱磷率随半钢温度升高呈上升的趋势;随着脱磷渣碱度上升,脱磷率呈先上升后下降的趋势,脱磷渣碱度为3.26时,脱磷率最高,脱磷率为52.1%。In combined with the characteristics of converter semi-steel of Chengde Steel,industrial dephosphorization practice in 100 tladle with blowing oxygen lance and bottom blowing argon has been done.Experiments show that,high oxygen flow condition is favorable for improving the dephosphorization ability of slag;the dephosphorization rate increases with the rise of semi-steel temperature;the dephosphorization rate first increases and then decreases with slag basicity rises,the dephosphorization rate gets to maximum when the basicity is 3.26,and the dephosphorization rate is 52.1%.
