Abstract Channel type induction heating tundish can compensate the heat of molten steel in time and effectively, which is conducive to improving the quality of slab. A mathematical model of induction heating tundish with five streams and four channels is established to study the influence of the volume of impact zone on the flow of molten steel in tundish. The results show that when the volume of impact zone accounts for 45% of the front chamber, the problems of bimodal flow and short circuit flow are effectively solved, the water distribution among the streams is more reasonable, and the flow performance of molten steel in tundish is better. The results show that the total residence time of tundish reaches 1 020 s, and the dead zone volume reduces to 11.5%. The time for the three nozzles to reach the peak is consistent, the maximum time difference is 49 s, and the average time to reach the peak is 335 s.
