Abstract：Effects of bottom blowing strength of combined blown converter， layout mode and flow distribution ratio on mass transfer coefficient in converter bath were researched through water simulation experiment. The results show that the mass transfer coefficient at the slag-steel interface increases at first and then decreases with the flow distribution ratio increasing， and the inflection points are not consistent at different bottom blowing strength. The mixing time decreases firstly and then increases with the flow distribution ratio increasing. With the bottom strength of 0.20 m3/（t·min） and bottom blowing ratio of 4[∶]1，the mass transfer efficiency at slag-steel interface is the best under the continuous arrangement， and the mass transfer coefficient can increase by 81.4% compared with conventional bottom blowing balanced gas supply mode. With the bottom strength of 0.15 m3/（t·min） and bottom blowing ratio of 2[∶]1，the mass transfer efficiency is the best under the interval arrangement， and the mass transfer coefficient can increase by 42.5%compared with conventional bottom blowing balanced gas supply mode. The continuous arrangement is better than the interval arrangement on improving the effect of mass transfer.
