非对称三流中间包结构优化的水模型研究

Water model study on optimization of internal structure in asymmetric three-strand continuous casting tundish

采用相似比为1∶2的水模型,对非对称三流中间包流场进行模拟研究。结果表明:原型中间包存在明显的短路流、死区体积比例较大以及各流水口的流动一致性较差等问题。通过对其结构进行优化,各流响应时间一致性较强,分散度降低至5.10,死区体积比例降低至13.15%,使中间包流场得到明显改善。

A water model with a similarity ratio of 1∶2 was used to simulate the flow field in an asymmetric three-flow tundish.The results show that the prototype tundish has obvious short-circuit flow,large dead-zone volume ratio and poor consistency of flow at each outlet.By optimizing the structure of the tundish,the response time of each flow is consistent,the dispersion is reduced to 5.10,and the dead zone volume ratio is reduced to 13.15%.The tundish flow field is improved obviously.
