Abstract：The flow field of 80 t refining ladle in a steel company was simulated by Fluent Software. The influences of different gas supply brick layout and argon flow on the ladle flow filed and mixing effect of the molten steel were analyzed. The results showed that for the bottom argon blowing ladle, the gas supply brick with 0.5R-0.67R-60° layout can reduce the slag entrapment and decrease the mixing time. Application showed that the reformed ladle shorten the mixing time of the molten steel 10 s and the total amount of inclusions was reduced by 1 800 (in 50 fields of view) by soft blowing of 10 min, significantly improving the refining effect.
