Abstract: A threedimensional transient mathematical model was developed to investigate the inclusions movement and removal in the continuous casting tundish with channeltype induction heating. According to the force balance, the inclusion movement behavior was investigated by EulerLagrange approach. A mathematical model was established for the collision and coalescence of inclusions in tundish with different induction heating powers, and the effect of collision and coalescence of inclusions on the removal ratio was investigated. The results showed that the inclusions will be subjected to an electromagnetic pressure force when molten steel flows pass the channel and move to the channel wall, which is beneficial to the removal of inclusions. Collision and coalescence improve remarkably the removal ratio of small inclusions. The induction heating is beneficial to the inclusion removal, especially for the small inclusions.

Key words: induction heating, tundish, inclusion, collision and coalescence, electromagnetic pressure force
