Numerical Simulation of the Intracavity Optimization of CSP Tundish

As to the metallurgical process of CSP tundish, mathematical models of flow field, temperature field and inclusion movement of molten steel flow in tundish were established and flow, heat transfer and inclusion ability of molten steel in tundish of five different combinations of weirs and dams schemes were analyzed. The results show that scheme 5 is the best for its reasonable structure, residence time of liquid steel prolonged and conduciveness to inclusion floatation; Scheme 5 doesn't contain obvious low temperature area, exit and entry of the tundish temperature difference is 5 ℃; In scheme 5, 98.4% of 50 μm inclusions can be removed while 40 μm of the inclusion removal rate can reach 92.3%.
