Abstract：Channel induction heating has been pay widely attentions by metallurgical workers in recent years because it can effectively compensate the temperature drop of the molten steel in a tundish and its high heating efficiency along with simple equipment. However, the tundish structure with the induction heater is quite different from the conventional tundish, and the flow field cannot be optimized simply by adding retaining walls, dams or stabilizers. Aiming at the problems of a high pouring superheat degree and a large temperature difference between the edge flow and the middle flow for a five-strand channel induction heating tundish in a domestic steel plant, several schemes were designed and their effects on the flow field of the tundish were compared through water simulation in the present work. The optimized split channel scheme A6 can reduce the dead zone fraction of the tundish from 29.50% to 20.33%; the average residence time is prolonged by 40s compared with the straight-through prototype scheme, and the consistency of each strand is significantly improved. Industrial tests show that the temperature difference between the edge strand and the middle strand of the optimized split channel is 3.5°C lower than that of the prototype channel, and good application results have been achieved.
