摘要

研究了300t顶底复吹转炉1:10几何相似比的水模型顶枪枪位（150~230mm）和流量（44~48m

/h）对钢液混匀时间的影响。模拟结果得出

最佳枪位为170mm

最佳流量为45m

/h。钢厂300t顶底复吹转炉应用结果表明

顶吹流量60000m

/h和底吹流量1000m

/h时

当顶枪枪位由1900mm改进为1700mm时

碳氧积平均值由原来的27.94降为23.49

提高了转炉内熔池的搅拌效果

吹炼时间由原15.8min降低至15.5min

降低了生产成本。

Abstract

The effect of top oxygen lance level (150~230mm) and flow rate (44~48m

/h) of geometric similarity 1：10 water model for 300t top and bottom combined blowing converter on mixing time of liquid has been studied. It is obtained by simulation results that the optimum lance level is 170mm and optimum flow rate is 45m

The application results of 300t top and bottom combined blowing

converter show that with top lance flow rate 60000

and bottom blowing flow rate 1000m
