Description
Minimizing the melt disturbance at the beginning of the teeming process during ingot casting is the key to ensuring high-quality steel production since this would minimize mould flux entrapment and decrease the reoxidation of the liquid steel. This study performs computational fluid dynamics (CFD) modeling to simulate the initial stage of the ingot casting process with different runner and inlet designs, such as by adding baffles to the runner, by placing the inlet tangential to the mould, and by modifying the trumpet’s design. Both qualitative (e.g. hump height, free surface area) and quantitative (e.g. velocity profile, oscillation of surface) evaluations are performed for the different designs and are benchmarked against today’s standard uphill ingot casting process. The results can be used to improve the existing casting geometry, and also to gain in-depth knowledge about the transient flow behavior during the ingot casting process to facilitate further process optimization.
