Abstract: Taking the six-strand splayed channel type induction heating tundish used by a domestic factory as the research object,in order to improve the flow field characteristics of prototype tundish,reduce the temperature drop, and uniform the temperature of each outlet,a scheme of add a reducerwas proposed andthe flow field and temperature field of the eight-character induction heating tundish were studied by means of water simulation and numerical simulation.The results show that the flow field distribution in the prototype tundish is unreasonable and the temperature difference is obvious.The flow to the middle of the tundish is less, and there is a large low temperature zone in the middle of the tundish.The temperature of each outlet is 1768 K, 1765.54 K,1753.23 K;After the addition of the reducer, the distribution of the flow field can be effectively improved, the flow to the middle of the tundish can be increased, and the temperature uniformity can be improved. The temperature difference of each outlet is controlled within 3 K, the temperature of each outlet is 1761.77 K, 1760.46 K, 1763.08 K.
