摘　　要：中间包内钢水的流动特性对钢水的净化有重要作用,介绍了中间包流场控制新技术,如湍流控制器、气幕挡墙、中间包吹气技术和离心式中间包技术等,合理的中间包结构设计可以改善内部流场,降低湍动能,延长钢液停留时间,有利于夹杂物的去除和钢水成分、温度的均匀。Flow field in tundish is very important for liquid steel purification. Some measures to help liquid steel purification such as turbulence inhibitor（TI） , gas bubble curtain, centrifugal tundish and gas injection in the ladle shrouding tube are introduced. Configuration optimization on tundish can effectively change the flow field in tundish. The dynamic energy of turbulence can be diminished, and the residence time of liquid steel in tundish can be prolonged. Those help inclusions removable and steel chemical composition and temperature uniformed.
