Abstract
To explore the effect of intermittent induction heating mode on inclusions in the tundish, a three-dimensional coupled electromagnetic field, flow field and inclusion field were developed. Numerical results show that medium frequency medium heating and medium frequency medium pause mode and head-to-tail long heating mode are beneficial to the removal of inclusions in the channel. At the same time, these two induction heating modes can not only help the macroscopic transmission and collision growth of inclusions but also help the removal of inclusions, which are two very good induction heating modes. The overall order of magnitude of the turbulent collision source term during induction heating is one order of magnitude higher than that of the turbulent collision source term without induction heating, and the difference within the channel is nearly two orders of magnitude, suggesting that the reasonable heating mode and heating time can help maximize the collision growth and removal of inclusions in the channel.
