Flow Field Simulation and Optimization of Ten-Strand Tundish for Billet Continuous Casting
In order to enhance the distribution of the liquid steel flow field within the tundish,reduce the volume of the dead zone and improve the efficacy of inclusions removal,a combination of physical and numerical simulation is employed to optimize the characteristics of the liquid steel flow field and temperature field under different internal structures of ten-strand tundish.The results demonstrate that in comparison to the impact zone retaining wall,the combination of a turbulence inhibitor and a baffle wall with deflector holes enlarges the volume of the impact zone,effectively reduces the turbulence energy of the liquid steel in the impact zone,and significantly improves the flow field and temperature distribution of the liquid steel in the tundish.The average residence time of the liquid steel in the tundish was found to be 820 seconds,with a dead zone percentage of 13.03％.Additionally,the temperature difference of the liquid steel in each flow outlet was observed to be 1.2 ℃,which represents the optimal effect of the baffle wall with double deflector holes(supported by four rods)and turbulence inhibitor.
