| 摘 要： | 以某钢厂四流中间包为研究对象,根据相似原理建立了1∶3的物理模型。模型研究了不同结构的挡墙、导流孔和湍流抑制器对中间包内流动特性的影响。实验结果表明,"Y"型挡墙和梯形湍流抑制器(方案F)组合的控流装置能获得相对较优的实验结果。采用方案F的控流装置后,总体的死区比例从原型的23.69%降为8.02%,钢液能得到更为充分的混匀;各流平均停留时间的标准差从原型方案的23.56降低到7.34,各流一致性也得到了明显的改善。

| Abstract: | A four-strand T type tundish is studied by using water modeling based on similarity principles.A 1∶3 physical model is built to study the influence of different walls,diversion holes and turbulent inhibitors on flow characteristics.The results show that the flow control device of “Y”type baffle+trapezoidal turbulent inhibitor (case F)apparently favor the flow pattern of the tundish.When the flow control device of case F is equipped,the proportion of dead zone goes down from 23.69% to 8.02% which means that the molten steel could mix well;the standard deviation of the average residence time is decreased by 68.85%, which infers that the consistency among all strands is also improved. |
