Abstract Scope |
The influence of channel height on the flow, heat transfer and inclusions removal behaviour of the dual-channel six-strand induction heating (IH) tundish is analysed by establishing a three-dimensional coupled electromagnetic-flow-thermal numerical model and the Lagrangian Discrete Phase Model. The results show that as the channel height increases, the molten steel at the exit of channel with IH changes from a significant downward flow to an upward flow, but the level fluctuates too sharply at 500 mm. Compared with the condition of IH turned off, the inclusion removal ratio of channel heights for 300mm, 400mm and 500mm under IH increased by 10.13%, 14.27% and 12.38%, respectively. It is suggested that the channel height of 400 mm not only can avoid the short-circuit flow tendency of the strand 2 and improve the inclusions removal ratio, but also it will reduce the risk of slag entrapment by excessive liquid level fluctuations. |
