In view of excessive non-metallic inclusion content in a five-strands symmetric casting 150 mm×150 mm bloom,the effect of different flow control devices on flow field of liquid in tundish has been studied by means of numerical simulation in order to get optimum baffle. The results reveal the prototype tundish presents the problems such as short average residence time,large dead zone and erosion in the tundish by molten steel. When using the optimum new U-type baffle,average residence time increased by 257.11 s and dead area volume fraction decreased by 27.31%,the standard deviation of average residence time of each nozzle was smaller. Field experiment results shows that T[O]in liquid in tundish decreases by 45.81% and the amount of large inclusions decreases considerably.
