摘　　要：以天钢120tLF为原型,在相似原理的基础上,通过水模型试验,研究考察了底吹氩量对出钢过程及吹氩精炼过程钢液混合效果的影响,对精炼钢包内的渣金卷混行为进行了研究,并考察了不同操作工艺参数(时间、吹氩量)对钢包内夹杂物去除的影响规律,进而对原工艺的改进提供了依据。A physical modeling system was set up from the similarity theory for the bottom blowing argon process in a 120 t ladle of Tianjin Iron and Steel Group Co.,Ltd.Through the water model experiments,the influence of different bottom blowing conditions on the complete mixing time in the ladle was measured,and the slag entrapment in ladle has been investigated.The influence of different operation parameters（time and flow rate of argon blowing） on non-metallic inclusions removal effect in ladle has been investigated,which provide the basis for improvements of original process.
