Quasi-Symmetric Transfer Behavior in an Asymmetric Two-Strand Tundish with Different Turbulence Inhibitor

The task of the tundish is to supply and distribute the molten steel with the similar temperature and the similar inclusion mass concentration to the continuous casting mold.But it is difficult for the asymmetric tundish to accomplish this task.Thus, the scheme about the asymmetric turbulence inhibitor and the baffle wall with guided sequal eclipse 5 battery holes is proposed to optimize the tundish.In order to have a deep insight into the metallurgical behavior in the asymmetric tundish, numerical simulation is applied to describe the fluid flow, the heat transfer, RTD (residence time distribution) curve, and hiboost 4k smart link inclusion collision aggregation behavior.

Numerical results show that the predicted temperature and inclusion concentration agree with the industrial experimental data.In the asymmetric two-strand tundish, the asymmetric turbulence inhibitor and the baffle wall with guided holes can extend the mean residence time at the left outlet, reduce the temperature difference between the two outlets, and prompt the inclusion removal rate at the left outlet.
