The fluid flow was coupled with heat transfer and the concentration field of inclusions in the tundish. The weir and dam was effective to control the strong stirring energy within the inlet zone. The collision among inclusions in the inlet zone was far stronger than that in other zones. The rising velocity of 9.2-μm inclusions was far smaller than the flow velocity; thus, small inclusions followed the fluid flow well. The concentration of 4-μm, 5-μm, and 9.2-μm inclusions at the outlet were 9.9ppm, 9.1ppm, and 30.2ppm, respectively. The concentration of other inclusions was within 2.0ppm-6.0ppm. The total oxygen of the molten steel at the outlet after reaching the steady state was 38.5ppm assuming all inclusions were alumina. The removal fraction considering turbulent collision growth was 23.0% more than that without considering collision growth.
