摘　　要：通过水模型的正交实验和数值模拟实验分析并验证了导流隔墙的尺寸参数对国内某厂不对称中间包内部流场的影响。水模拟实验结果表明最佳的尺寸参数为:A2B3C3D3,其中A、B、D因素为显著因素,C因素对结果影响不显著。数值模拟实验对原型、改良中间包的流场和温度场进行了对比分析,表明优化后的中间包的温度场流场得到了明显改善。The effects of the baffle parameters in the asymmetric tundish in a plant have been investigated in the paper by the orthogonal tests of water modeling experiments and numerical simulation. The results of water modeling show that the best baffle parameters are A2B3C3D3, and that A, B, D are significant factors and C aren＇t. The flow fluid and temperature fluid of the prototype and improved tundishes have been analyzed by numerical simulation experiments. The results show that the flow fluid and temperature fluid of optimized tundished are improved.
