摘要：

In continuous casting process, cleanliness of steel can be improved and maintained by promoting the inclusion separation inside the tundish by various means; tundish flow optimization using arrangement of flow control devices inside the tundish is one among them. Three-dimensional computational fluid dynamics simulation of tundish flow is an efficient way to investigate the arrangement of flow control devices. In the present work, three-dimensional isothermal steady-state flow simulations, residence time distribution analysis and inclusion transport simulations of tundish flow are conducted. All the simulation results are validated with experimental measurements reported in literature. Subsequently, the simulations are extended for a non-isothermal flow of the existing tundish in the plant and an additional flow control device, namely a weir with appropriate dimensions is proposed which indicated better steel flow in the tundish with more inclusion separation efficiency as compared to the existing bare tundish.
