WATER MODEL STUDY ON MECHANISM OF INCLUSION REMOVAL IN CONTINUOUS CASTING TUNDISH
连铸中间包内夹杂物去除机理的水模型研究

The effects of flow control device, casting speed of liquid steel and inclusion size on inclusion removal in continuous casting tundish were investigated by water model, in which emulsion drops were chosen as inclusions. The results show that the removal efficiency of inclusion 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 removal efficiency of inclusion. It seems to be difficult to improve the removal efficiency of inclusion only by optimizing the flow control devices in tundish as using high casting speed of liquid steel.
