Physical Simulation Study on Flow of Molten Steel in Tundish of Slab Caster
The effects of flow control device on flow conditions of molten steel in tundish are studied with the method of physical simulation through establishing physical model of tundish for double-strand slab caster with geometric similarity ratio of 1∶4 based on the similarity principle. The results showed that the peak time and average retention time of molten steel in tundish were increased,volume of dead zone for molten steel in tundish was reduced due to the optimized flow con-trol device was adopted by tundish of slab. The peak time of molten steel is increased by 240.98％,average retention time of molten steel is increased by 2.37％ and volume of dead zone is reduced by 7.56％. As a result,the flow conditions of molten steel in tundish are optimized as well as collision,aggregation,floatation and removal of inclusions in tundish are promoted so that the cleanliness of molten steel is ensured.
