| 摘 要： | 分析中间包内钢液的停留时间分布（RTD）曲线，从而定量描述其内流动特性的组合模型已被应用数十年，但对于多流中间包，目前还没有公认的流动特性分析模型．本文提出了针对多流中间包流动特性的分析模型，为多流中间包内的活塞区、混合区、死区体积分数的定量计算提供理论依据，并与已有的分析方法进行了比较．

| Abstract: | A combined model to characterize the melt flow by analyzing the residence time distribution in a tundish had been applied for several decades. However, no well-known model to characterize the melt flow was presented for multi-strand tundish at present. In this paper, a model to characterize the melt flow for multi-strand tundish was presented to calculate the fractions of plug flow, mixed flow and dead volumes, and the model was compared with those of the presented approaches. |
