摘　　要：讨论了转炉溅渣护炉过程中各参数的影响,试验以修正的弗鲁德数(Fr)作为相似基础.实验室采用石蜡加淀粉对30t转炉进行了模拟研究.通过对试验数据的处理和分析,得到了最佳的工艺参数:氮气流量约为8500m^3/h,溅渣时间为3min,枪位为0.8m;向渣中加入氧化镁或碳粒以调整成分是必要的;炉渣温度过高,流动性过好,溅起的炉渣难以凝结在炉衬上.Several parameters affecting slag splashing in LD converter have been discussed. Using paraffin and starch model, a simulated test about 30t converter has been made in laboratory and the modified Froude number was chosen as the main similar basis of the system. It was results that the optimized slag splashing parameters was obtained through data treatment. The nitrogen gas flow rate is about 8 500m^3 / h, the splashing time is of 3 min, and the lance height is of 0.8m. It is necessary to add MgO or carbon into the slag to adjusting slag composition. Also, it is difficult for the splashed slag condensing on the line when the slag temperature is much higher.
