摘　　要：通过数学物理模拟方法研究了三流中间包在不同控流装置下的流体流动特性,并采用平均停留时间作为特征参数对多流中间包流体流动性进行评价。数值模拟结果表明:设置多孔挡墙后,中间包流体流动特征为流体通过多次循环流动到达导向孔,而后通过多次循环流动到达中间包出口。水模型实验表明:设置多孔挡墙后,三流的平均停留时间的平均值由305 s增加到573 s,增加了87.9%;而三流的平均停留时间的最大差异则由15.1%下降到11.3%。Mathematical and physical simulation were applied to study the flow character in an three-strand continuous casting tundish, and the average residence time is chosen to be the key parameter to describe the flow characteristic in the multi-strand tundish. Numerical results show that there is great change of the flow characteristic in the tundish after the introduction of multi-hole baffle. At first, the fluid reach the guide hole by reeeireulation movement, and then flow toward the exit by recirculation movement. Water modeling results show that after the introduction of multi-hole baffle, the mean value among the average residence time at the three exits rises by 87.9% from 305s to 573s while the maximum difference among the average residence time at the three exits falls from 15.1% to 11.3%.
