| 摘 要： | 通过三流T型连铸中间包物理模拟实验，研究了直挡墙、V型挡墙及其与抑湍器组合控流装置对中间包流动特性的影响。结果表明，直挡墙控流装置的控流效果优于无控流装置的中间包，但不如设计合理的V型挡墙控流装置；V型挡墙与挡坝组合控流装置（方案Ⅴ）的控流效果较好，在其基础上加入抑湍器后控流效果并不理想。因此，提出了针对三流T型中间包控流装置的优化设计方案。

| Abstract: | The effects of vertical and ＂V＂ type baffles as well as turbulence inhibitor with baffle on melt flow behavior were investigated in a three-strand T type tundish with physical modeling. The results show that the vertical baffle placed in tundish without any control device improves the melt flow for inclusion removal, but it loses the advan tage compared with the reasonable designed baffle of ＂V＂ type. ＂V＂ type baffle and dam can improve the melt flow, while the addition of turbulence inhibitor based on it seems to be no any improvement for the flow. In present study, an optimal proposal for flow control devices in tundish is presented through an optimizing study by water modeling. |
