LF双孔底吹优化布置的水模型研究

Water model study on optimization of LF argon blowing with double nozzles

以国内某钢厂150 t LF为原型,通过水模型实验,对钢包原吹氩位置的合理性进行了分析和探讨,对双孔底吹不同底透气砖布置条件下钢包内的搅拌混合行为进行了研究,提出了该厂LF较佳底吹气搅拌位置及吹氩制度,并考察了有顶渣情况下的液面隆起的变化规律.

Water modeling experiments were carried out for a 150 t LF from a domestic steel plant. Through the experiments, the rationality of the position for argon blowing was analyzed and discussed, and the stirring behavior of ladle with double nozzles in different arrangements was investigated, arriving at the optimization of nozzle arrangement and gas flow rate for argon blowing. The upswell on the liquid surface with slag layer was also investigated.
