应用Fluent软件对某钢厂80 t精炼钢包流场进行数值模拟，分析了不同透气砖布置和不同氩气流量对钢包流场及钢液混匀效果的影响。结果表明，底吹氩钢包透气砖采用0.5R-0.67R-60°的布置方式可以减少卷渣，减少混匀时间。应用表明，改造后的钢包缩短钢液混匀时间10 s，软吹10 min后夹杂物总量减少1800个（50个视场），明显提高了精炼效果。
應用Fluent軟件對某鋼廠80 t精煉鋼包流場進行數值模擬，分析瞭不同透氣磚佈置和不同氬氣流量對鋼包流場及鋼液混勻效果的影響。結果錶明，底吹氬鋼包透氣磚採用0.5R-0.67R-60°的佈置方式可以減少捲渣，減少混勻時間。應用錶明，改造後的鋼包縮短鋼液混勻時間10 s，軟吹10 min後夾雜物總量減少1800箇（50箇視場），明顯提高瞭精煉效果。

The flow field of 80 t refining ladle in a steel company was simulated by Fluent Software. The influences of different gas supply brick layout and argon flow on the ladle flow filed and mixing effect of the molten steel were analyzed. The results showed that for the bottom argon blowing ladle, the gas supply brick with 0.5R-0.67R-60° layout can reduce the slag entrapment and decrease the mixing time. Application showed that the reformed ladle shorten the mixing time of the molten steel 10 s and the total amount of inclusions was reduced by 1 800 (in 50 fields of view) by soft blowing of 10 min, significantly improving the refining effect.
