摘要
根据相似原理,对兴澄特钢150t钢包建立几何比例为1∶3的水力学模型,在对原型进行评估的基础上对吹氩位置进行改进,确定最佳吹气方案为:双孔位于半径的1/3处和半径的0.64处,成180°夹角布置,实际吹气量为600L/min时得到最小混匀时间48.8 s。
According to the similar principles, water model with geometric ratio of 1 ： 3 was set up for 150t ladle of Xingcheng special Steel. On the basis of the prototype evaluation, the position of argon blo- wing was improved and the optimal project was that bottom nozzle positions were at the radius of 1/3 and 0.64 with the angle of 180°and when the actual flow rate was 600L/min, the shortest mixing time was 48.8s.
