Numerical Simulation of Flow and Temperature Field in Continuous Casting Tundish

Using the turbulence theory,the mathematical model was built to describe the temperature field in tundish.The steel flow and heat transfer have been investigated in a billet concasting tundish at Kunming Iron and Steel.The molten steel flow and heat transfer behavior was studied after setting up weirs in tundish.The calculation results of flow field show that the molten steel stay longer in tundish and the flow patterns of each strand tend to be uniform after using suitable weirs;The calculation results of temperature field show that the temperature differences of each strand are obviously reduced after setting up weirs.
