摘　　要：通过水力学模拟实验,在1:6的物理模型上,对承钢150t提钒转炉的底吹元件布置进行优化,运用测电导率法测定了7种不同底吹元件布置方案转炉熔池的混匀时间。实验结果表明:方案3熔池混匀时间最短,为最佳底吹元件布置方案;在本试验条件下,枪位在225 mm,顶吹气体流量为81～83.3 m^3/h.,底吹气体流量为1.8 m^3/h时,可获得最短熔池混昆匀时间。The experiment have been carried out in a 1/6 scale water model of 150t vanadium extraction converter, in order to optimize the bottom tuyere configuration. The mixing time of seven different bottom tuyere cases was obtained via measuring the conductivity. The results show that the case 3 with the lowest mixing time, is the best bottom tuyere configuration. Under the conditions of this experiment, the gun under the condition of gas flow rate for 225mm top lance level, top-blown air flow for 81-83.3 m^3/h, bottom blowing air flow for 1.8 m^3/h, the shortest mixing time can be obtained.
