The numerical simulation results are in good agreement with the experimental data of water model under the same experimental conditions. Then the numerical simulation method is presented to investigate the flow field, the vortex on gas-liquid surface and the uniform mixing time in hot metal ladles. This research shows: the vortex depth increases with increasing of immersion depth and rotation speed; Overflow appears in N=120rpm and h=3.2m; the turbulent kinetic energy increases with increasing immersion depth and rotation speed; uniform mixing time decreases with the decreasing of immersion depth and the rotation speed of stirring ; the optimal uniform mixing time is 23.5s on the conditions of N=100rpm and h=3.2m within the allowable range. 关键词：KR VORTEX uniform MIXING time TURBULENT KINETIC energy numerical simulation
