摘　　要：以某钢厂230t钢包为研究对象。通过实验水模型对现场生产过程的模拟，研究底吹透气元件的布置方式和吹氩流量对搅拌效果和夹杂物去除率的影响。结果表明．双透气元件吹氩优于单透气元件吹氩搅拌效果，0．6R-γ双透气元件布置方式最佳，混匀时间随吹气量和透气元件夹角的增大而减少；夹杂物的去除率取决于吹氩量和吹氩时间，在0．2～0．8L／min吹气量下，处理时间为0～4min时夹杂物去除效果最好，5～8min时可去除大部分夹杂物，24min左右可去除所有夹杂物。Study of a 230 t ladle in a certain steel plant is carried out by water model in the lab to work out how the number and layout of ventilation devices and flow rate of bottom blowing argon influence the stirring effect and inclusion removal. The results show that during the stirring for mixing, bottom blowing argon with 0.6R-γ scheme is the most ideal choice after considering all the factors, and the mixing time decreases as the flow rate of argon and angle of ventilation devices increases. What＇s more, during the inclusion removing process, the best effect can be obtained in the first 4 minutes under a little flow rate. And at about 8 minutes, most of the inclusions can be removed. Almost all the inclusions can be removed within about 24 minutes in the lab.
