摘要
In order to clarify the stirring mechanism of a bottom-blown bath, the volume of fluid (VOF) multiphase flow model was used to simulate the gas-liquid two-phase flow process. The simulation results were verified by water model test, and the influence of gas-liquid mixed melt process was analyzed. The results show that the separation effect of matte is better when the injection angle is between 15 degrees and 22.5 degrees. When the gas velocity is 70 m/s, the gas stirring radius is 1 m, so the distance between the oxygen lance and the furnace wall is 1-1.5 m, which can ensure that the furnace wall is not washed by excessive melt. The optimum spacing of the oxygen lance is controlled at 2-3 m, the distribution of oxygen lances is more reasonable, the effect of bath agitation is better, and the splash caused by excessive bath agitation is prevented.
