摘　　要：对某厂210t顶底复吹转炉进行了溅渣护炉水模型实验,测定了炉衬不同部位的溅渣量,考察了操作参数对溅渣效果的影响,得到最佳工艺操作参数为:顶吹流量50000Nm3/h,枪位3680mm,氧枪喷头倾角15°,留渣量21t,底吹元件布置方式A1,底吹流量900Nm3/h.Simulation experiments with water as slag on slag splashing in a 210 t top-bottom combined blowing converter were carried out.By measuring the amount of water taken as slag splashed onto the lining,the effects of operating parameters on slag splashing were examined,the optimal parameters were obtained as follows：top-blown gas flow rate was 50000 Nm3/h,lance height around 3680 mm,nozzle angle 15°,amount of slag remained for splashing 21 t,layout A1 of bottom tuyeres and bottom flow rate about 900 Nm3/h.
