摘　　要：基于不同的底吹氩工艺方案,对90 t钢包开展了水模拟试验研究,分析了流量、单孔、双孔、孔所处钢包半径位置等工艺参数对钢包内钢液混匀时间的影响。结果表明:不同方案下,混匀时间均随流量的增加呈减小的趋势,在一定范围内,提高流量是减少混匀时间的有效手段。不同方案下,混匀时间的减小,基本都存在拐点,在拐点后继续增加流量,混匀时间随流量增加而减小的趋势减弱,生产成本增加。水模拟试验结果显示:单孔条件下,钢包半径0.62R处吹氩混匀时间最短;双孔条件下,在同一圆周0.62R处呈56.3°夹角时处吹氩混匀时间最短,该方案与原型比,可缩短24.7%的混匀时间。Based on different bottom argon blowing process,water simulation test was carried out for 90 t ladle,the influence of process parameters such as flow rate,single hole,double hole and the radius position of the hole on the mixing time of molten steel in ladle is analyzed.The results show that the mixing time decreases with the increase of flow rate.In a certain range,increasing the flow rate is an effective way to reduce the mixing time.There is an inflection point for the decrease of mixing time under different schemes,and the flow rate increases after the inflection point,the trend of mixing time decreasing with the increase of flow rate,and the production cost increases.The results of water simulation test show that the mixing time of argon blowing is the shortest at the radius of 0.62 R of ladle under single hole condition,and the mixing time is the shortest at the angle of 56.3°at the radius of 0.62 R of ladle under double hole condition,compared with the prototype,the mixing time can be shortened by 24.7%.
