Numerical Simulation Study on Optimization of Large-Capacity Single-Strand Tundish Flow Control Devices

摘要

In this paper, according to the large-capacity tundish with single-strand and rectangular structure, the mathematical simulation method is used to study the effect of the flow control devices of the weir and the dam on the flow field, temperature field, and inclusions trajectories of molten steel. The orthogonal experiment method is used to study the effect of the distance between the weir and the bottom of the tundish, the distance from the weir to the long nozzle, the distance between the weir and the dam, the height of the dam on the flow pattern, temperature distribution, and inclusion removal rate of the molten steel in tundish. The reasonable flow control devices and the installation position could be obtained by analyzing the results of mathematical simulation, and it can provide theoretical guidance for actual production.
