摘　　要：介绍了中间包内钢液流动特性分析模型的研究进展,针对中间包内钢液的去夹杂流动特性,论述了典型的单、多流中间包去夹杂流动特性分析模型,并通过对比分析找出了较优的单、多流中间包去夹杂流动特性分析模型。对于多流中间包内钢液的流动特性,不仅要考虑非金属夹杂物的去除,还要考虑多流中间包内各流流动特性的一致性,对比分析了典型各流流动特性一致性分析模型的特点并找出了合适的分析模型。所找到的合理的去夹杂及各流流动特性一致性分析模型为中间包内钢液流动特性分析提供了理论依据。The latest progress of analysis model for flow characteristics in continuous casting tundish is introduced. Typical analysis models to characterize the melt flow for inclusion removal in single-strand and multi-strand tundishes are compared and the optimal analysis models for inclusion removal both in single-strand and multi-strand tundishes are founded. In multi-strand tundishes, besides the inclusion removal, the strand similarity is also need to be taken into account when modifying the melt flow. Therefore, typical analysis models to quantify the similarity among the strands in multi-strand tundishes are analyzed and an optimal analysis model for strand similarity is affirmed. Those optimal analysis models for inclusion removal and strand similarity can provide quantitative theoretical basis for flow characterization in tundishes.
