Simulation Optimization Research of Tundish under Different Pull Speeds

In this paper,asymmetric tundish of three-strand casting construction model for different speeds and the existence of dam had been investigated. In order to further improve the production capacity of the tundish of electric furnace factory,a water simulation and numerical simulation scheme was designed for three-flow asymmetric tundish. Through numerical simulation on velocity field and temperature field and water model at different casting speeds,it can be found that increase casting speed,will lead to decrease the dwell time of the three nozzles,and the time for three nozzles is different After dam installation,the decrease of dwell time with casting speed becomes small. The distribution of flow field and temperature filed do not vary with casting speed,however,increasing casting speed will increase the flow and temperature of liquid steel in tundish.
