通过六流矩形坯连铸中间包的水模试验，研究了不同控流装置对其流动特性的影响。研究结果表明，稳流器和多孔挡墙能明显改善各流流动特性的一致性，在此基础上加设方形孔挡墙能有效减小死区体积。合理的中间包组合控流装置为稳流器+多孔挡墙+方形孔挡墙。

The water model of a six-strand continuous casting tundish for rectangular bloom was built to study the effects of various flow control devices on melt flow. The results showed that the current regulator as well as multi-hole dam can improve the similarity among the six strands distinctly, and the addition of rectangular-hole dam based on the current regulator with multi-hole dam can decrease the volume of dead zone. The rational flow control device in the tundish is a current regulator with two multi-hole dams and a rectangular-hole dam.
