Abstract：Two flow control devices which are inverted eight type and V type weir were put forward in order to improve the characteristics of flow field in the new 4-strand H-type double channels tundish with induction heating in a special steel plant. The flow field, RTD curve and temperature field in tundish with different flow control devices were simulated by numerical method. The results show that the average residence time of the inverted eight type is 1 469.6 s, the dead zone volume fraction is 5.83%, and the maximum temperature difference between the edge nozzle and the middle nozzle is 3 K. Compared with the V-type flow control device, the average residence time is prolonged by 41.9 s, the dead zone volume fraction is correspondingly reduced by 4.09%, and the maximum temperature difference between the edge nozzle and the middle nozzle is reduced by 2 ℃. The design of turbulence suppressor + inverted eight flow control device has better flow control effect on the new 4-strand H-type double channels tundish with induction heating.
