Study on Optimizing Flow Control Devices for Slab Continuous Casting Tundish by Water Modeling

Jinzhong Xiang

Abstract

Water model experiments were taken to install proper flow control devices for a slab continuous casting tundish.Cases of weir + dam were optimized by orthogonal experiments.The results show that there are short circuit flow and large dead volume in the tundish without flow control devices.Case 3 can obviously improve the flow field,which lengthens the average residence time,makes dead volume decrease,plug volume increase.Furthermore,the flow is close to the surface when case 3 is used,which is helpful for inclusion removal.
