A New Analysis Method for Flow Field and Inclusion Behavior in a Tundish With Channel‐Type Induction Heater

Tundish with channel‐type induction heating is a popular operation for clean steel production. The relationship between the electromagnetic force proximal to the channel wall and the included angle closely resembles a sinusoidal function. Due to a unique physical structure where the receiving chamber is separated from the discharging chamber, three combined models are applied in receiving chamber, channel, and the discharging chamber, respectively. After induction heating, the plug volume fraction rises 1.89 times in the receiving chamber, the well‐mixed volume fraction increases by 5.28 times in the channel, the well‐mixed volume fraction increases by 25.46% in the discharging chamber. Furthermore, the inclusion mass/population conservation model, which involves electromagnetic force effect is applied to predict inclusion behavior in this study. The receiving chamber and discharging chamber are the main areas for inclusion removal.
