Study on Optimization of Flow Control Devices in Two Strand Slab Continuous Casting Tundish

Based on the similar theory, water model of two strand slab continuous casting tundish was established in the ratio of 1:3.The inner structure of tundish is optimized by the combination of weirs and dams with different heights and positions.The experiment results show that the minimum residence time in the modified tundish increases from 83 s to 97 s, the mean residence time increases from 296 s to 432 s, the dead zone volume decreases from 46% to 21% and all the microscopic fluctuations decrease from 0.04 ms/cm to 0.025 ms/cm, the goal of optimizing the inner structure of the tundish has been achieved.
