Abstract

The continuous casting tundish has evolved into a useful reactor for liquid steel refining. The appreciate flow control devices such as dam, turbulence inhibitor and gas blowing, helps to modify the pattern and minimize short circuiting and dead zone. In this paper, a commercial computational fluid dynamics (CFD) package FLUENT was used to predict the flow field under steady state in one-strand tundish. The effects of flow control devices, gas bottom-blowing flow rate on flow field and residence time distribution (RTD) were studied. The results show that the molten steel flow state in optimized tundish has been improved significantly. When the gas blowing position was 1950mm from inlet axis and argon flow rate was 0.3m3/h, the average residence time of molten steel in the tundish was prolonged. And the volume fraction of dead zone in the tundish was reduced from 28.6% to 13.3%.
