主　　题：Thermal stratification Mixing time Open eye slag Ladle steelmaking Multiphase modeling 

摘      要：A numerical simulation was performed to study the flow pattern,mixing time and open-eye slag produced by argon gas injection in an industrial scale steel ladle under non-isothermal *** liquid steel remains 5min before the injection,and thermal stratification and convective flows were *** different sequences in stages employing various argon-gas flow rates were *** the first case,a sequence with the highest flow rates of argon was applied,while in the second and the third sequences,the intermediate and the lowest flow rates of argon gas were used,*** determining the chemistry homogenization,the mixing time was computed and analyzed in all three *** was found that the cold steel is located near the walls while the steel with a high temperature is accumulated in the center of the ladle above the argon-gas *** higher and lower flows promote a faster chemistry homogenization owing to the secondary recirculations that are developed closer to the *** results from steel temperature drop show a good concordance with plant trial measurements.
