摘要: 針對某電爐廠在冶煉軸承鋼過程中，鋼包底吹精煉混勻效果和去夾雜效果不佳的問題進行了水模型研究.實驗結果表明：鋼包原型底吹位置由于兩氣柱間距離較近，在大氣量下氣柱產生偏移和疊加，造成鋼液流場不穩定.根據實驗結果建議：底吹位置應位于0.5R-0.5R-135°（R為鋼包底部半徑）；該方案臨界卷渣氣量為0.24m³·h^-1.

Abstract: To improve the mixing effect and inclusion removing during the ladle bottom blowing refining process at an electric furnace factory,the water modeling experiment was conducted. Results show that the distance of two gas columns is too close,so stacking and shifting of the gas columns occur when the gas flow rate is large,which make the flow field of molten steel unstable. According to the results,it is proposed that the bottom blowing position should be located at 0.5R-0.5R-135°(R is the ladle bottom radius),and the critical gas flow rate for slag entrapment is 0.24 m³·h^-1.
