| 摘 要： | 以国内某钢厂五流连铸中间包为研究对象，根据相似原理建立了1：3的中间包水模拟系统，考察不同内部结构对中间包流体流动特性的影响．研究结果表明：原型中间包内部结构不合理，各流水口之间的流体流动特性差异很大，存在较大死区．通过内部结构优化设计，使中间包流场得到明显改善，其中方案Ⅵ效果最佳，平均停留时间离散度最小，活塞区体积达23．84％，死区体积为10％，比原型下降了71．70％．

| Abstract: | Based on the five-strand caster tundish in a domestic steel plant,water modeling system with the 1：3 similarity ratio is set up to study the effect of the different internal structure on fluid flow characteristics of tundish according to the similar principle. The results show that the unreasonable internal structure of prototype tundish and different flow characteristics between outlets with large dead zone volume and unfavorable mixing effect. The field characteristics of tundish are improved remarkably by optimizing the internal structure design. Of which, the scheme VI enjoys the optimal volume amounts to 23.84 % prototype tundish. mixing effects for its minimum dispersion degree of mean residence time. The plug with dead zone volume of 10 %, which is decreased by 71.70 % compared to the |
