Abstract ABSTRACT The effects of flow control device、casting flowrate of liquid steel and inclusion size on inclusion removal in continuous casting tundish were investigated by choosing emulsion drops simulated as inclusions in a water model. The results show that the efficiency of inclusion removal in tundish with weir and dams is relatively high due to the collision and aggregation of inclusions in high turbulence region and the improvement of flow field in tundish. Although the fluid flow has some change in pouring region with turbulence inhibitor in tundish, It has not much effect on the efficiency of inclusion removal. It seems to be difficult to improve the efficiency of inclusion removal only by optimizing the flow control devices in tundish with high casting flowrate of liquid steel.
