Abstract In order to further improve the product quality of a steel plant, the volume of its tundish has been expanded and the original flow structure has been changed. In this paper, the side hole of the retaining wall after the expansion of the three-stream tundish has been optimized to reduce the proportion of dead zone in the tundish and increase the utilization efficiency of the tundish. The tundish currently used in the plant has the problems of poor consistency of water inlets between streams and large proportion of dead zones. In this paper, the tundish retaining wall structure is optimized by numerical simulation using the fluent software of Ansys. Although the temperature difference between the flows in the tundish after the improvement of the side hole of the retaining wall is 0.9 ℃ higher than the original one, the proportion of dead zone is reduced from 21.48% to 14.70%, which effectively reduces the proportion of dead zone, improves the consistency between the flows in the tundish, and achieves a better metallurgical effect.
