| 摘 要： | 根据相似原理,对兴澄特钢150 t钢包建立几何比例为1∶3的水力学模型,通过测定不同底吹条件下钢包的混匀时间,确定最佳的底部透气砖位置及吹气流量。研究表明：原型双孔吹气方案下混匀效果欠佳,较大气量下气流股会对包衬造成冲刷侵蚀。优化后得到最佳方案为：双孔在1/2 R圆周上,成135°布置,吹气量控制在550～600 L/min,可获得最短的混匀时间为53 s。

| Abstract: | According to the similitude principle,1:3 water mechanical model has been established for 150 t ladle in Xingcheng Steel.The best bottom nozzle position and the gas flow rate are defined by measuring the mixing time under different bottom blowing conditions.The results show that the original program with two nozzles blowing is not good enough because of washing erosion to the ladle lining from too much blowing gas.The optimum program after optimizing is that the 53 s shortest mixing time can be obtained whe... |
