摘　　要：以某钢厂100 t钢包为研究对象,利用商业软件PHOENICS对该钢包内的流场进行数值模拟计算,研究钢包底吹氩精炼过程在不同工艺条件下对钢液混匀效果和包壁冲刷的影响。结果表明,底吹氩钢包内透气元件采用A-β方案,在避免钢液对包壁造成较严重冲刷和裸露的同时,有利于缩短钢包内钢液的混匀时间,从而获得较好的搅拌效果。This paper presents a study of a 100 t ladle in a certain steel mill.Using commercial software PHOENICS,it simulates mathematically the flow field of the ladle,and discusses the effects of different process parameters on the mixing effect and the erosion of the wall during the bottom blowing refining process.The results show that,with the A-β double nozzles,symmetrical arrangement can avoid serious erosion to the wall and exposure to liquid steel.Besides,this arrangement is good for reducing the mixing time of liquid steel in the ladle,which leads to better mixing effect.
