Abstract

Abstract

Fluid flow behavior of molten steel in tundish is a key factor which can influence solidification of the subsequent casting blank.Therefore,it is very necessary to design suitable flow control devices for tundish.The present research is based on the seven-strand "T" shaped tundish.According to the characteristics of "T" shaped tundish and the geometry size of seven-strand tundish,four kinds of flow control devices were designed.Velocity field,temperature field and effect of inclusion removal with different flow control devices were analyzed by using numerical simulation method.The results show that with flow control device "C",the uniformity of flow between strands is better than others,and the maximum temperature difference in tundish and between strands is 9 ℃ and 0.4 ℃ respectively,which shows relatively satisfied temperature uniformity.Also,the removal rate of inclusion reaches 89.12%.Thus,flow control device "C" is a suitable scheme for on-site use.
