摘　　要：针对钢厂150t底吹氩钢包于0．2R圆周上成90°布置的双孔吹氩，钢水成分和温度均匀性较差的问题，进行了几何相似比1：4，双孔吹氩位置0．2～0．8R，夹角45°-180°。吹气量54．6～491．4L／h（相当于150t钢包吹气量50～450L／min）的水模型试验。试验结果表明，最优方案为双孔半径0．6R圆周，夹角180°，每孔流量382．2L／h（相当于150t钢何350L／min）．混匀时间比原钢包的喷嘴布置减少28．6％。In accordance with the issue of poor homogeneity of composition and temperature of liquid in 150 t ladle bottom-argon-blowing with double nozzle located at 0. 2 R circumference in angle 90°, a test by using geometric similarity 1：4 water model with double nozzle location 0. 2 - 0. 8 R, in angle 45°- 180°, blowing rate 54. 6 N 491.4 L/h （ corre sponding 150 t ladle blowing rate 50 -450 L/min） has been carried out. Test results show that as compared with original ladle nozzle location, for the optimum scheme-double radius 0. 6 R circumference, in angle 180° and each nozzle flow rate 382. 2 L/h （corresponding 150 t ladle 350 L/min） the mixing time of liquid decreases by 28.6%.
