摘　　要：用Fluent软件和VOF模型模拟了130 t单嘴精炼炉内覆盖脱硫渣时钢包底吹氩流量(150～450L/min)和吹氩位置(中心至3/4浸渍管半径)对钢渣界面平均速度的影响。结果表明,吹气位置为1/2浸渍管半径(R)处最合理,钢渣界面平均速度随吹气流量的增加而增加,当流量一定时吹气位置为1/2R时界面平均速度最大;吹气位置>1/2R时才会对界面上渣相体积分数变化有显著影响。The effect of argon blowing rate （ 150 -450 L/min） and argon blowing location at ladle bottom （ladle cen- ter to 3/4 radius of submerged snorkel） on average flow rate at metal-slag interface in 130 t single snorkel furnace with de- sulphurizing top slag is simulated by Fluent software and VOF model. Results show that the suitable blowing location is at 1/2 radius （R） of submerged snorkel, the average flow rate at metal-slag interface increases with increasing blowing rate, with definite blowing rate and blowing at 1/2R the average flow rate at interface is maximum, and only as blowing location is 〉 1/2R, the effect of blowing location has obvious effect on variation of slag phase volume fraction at interface.
