AI Technical Summary
In a channel-type induction heating tundish, excessively high horizontal flow velocity of molten steel leads to poor inclusion removal and short residence time of molten steel in the tundish, affecting the quality of the cast billet.
By employing an electromagnetic induction heating device and an electromagnetic deceleration device, and adjusting the power and magnetic induction intensity of the electromagnetic induction heating device and the electromagnetic deceleration device, the flow rate and residence time of the molten steel are controlled, thereby extending the residence time of the molten steel in the tundish and improving the removal effect of inclusions.
It effectively reduces the superheat of molten steel, achieves constant temperature and constant casting speed process, improves the uniformity of billet quality and the stability of solidification structure, and enhances the removal effect of inclusions.
