进行中间包挡墙和坝的水模型实验，分析原方案的冶金效果，在此基础上提出优化设计方案。
By water simulation experiment on tundish dam and weir, metallurgical effect of the original design is analyzed and the optimal design scheme is offered based on these researches.
结果表明，在吹气条件下中间包采用挡墙控制有利于改善中间包流场，促进夹杂物上浮。
The results show that under bottom blowing the baffle control changes the flow field remarkably and improves the inclusion removal.
型挡墙，冲击区体积较小，钢液混合不均匀，钢液在整个中间包内的平均停留时间较短。
The pound region volume of the baffle C type is still too small, so the liquid steel can't mix sufficiently, and the average residence time in the tundish is short.
