摘　　要：原型中间包结构不合理,两个水口进出口温差不一致,且包内温降较大.优化后中间包温度分布更加合理,进出口温差减小,最低温度有所提高,尤其方案3效果最佳.The design of the original tundish was improper in that the temperature difference between the inlet and outlet for each of the two nozzles was inconsistent, and too high a temperature drop occurred within the tundish. By optimizing the tundish structure, a proper temperature distribution within the ttmdish was obtained, the temperature difference between the inlet and outlet decreased, and the minimum temperature within the tundish slightly increased, while with scheme 3 yielding the best result.
