Numerical simulation of the top side-pouring twin-roll casting of 6.5 wt.% Si steel process

Using the finite element software ProCAST to predict the temperature field, the flow field, the turbulent kinetic energy, and melt-pool outlet temperature of the top side-pouring twin-roll casting (TSTRC) of 6.5 wt.% Si steel process. The effect of different process conditions on the TSTRC process was investigated through numerical simulation, and a processing technic appropriate for the production of 6.5 wt.% Si steel was obtained. Meanwhile, the influence of violent stirring in the melt-pool on the microstructure under different process conditions was evaluated. The results showed that vigorous stirring in the melt-pool was conducive to formate the equiaxed crystal structure. We realized the near-final shape of the metal sheet and achieved the near-final shape of the microstructure. An appropriate process was selected to show good consistency with the experimental results.

Automated summary

Using finite element software ProCAST, the study predicted the temperature and flow fields, turbulent kinetic energy, and melt-pool outlet temperature in the top side-pouring twin-roll casting (TSTRC) process for 6.5 wt.% Si steel. The research investigated the impact of different process conditions on TSTRC and determined an appropriate processing technique for producing 6.5 wt.% Si steel, while also evaluating the influence of violent stirring in the melt-pool on microstructure formation. The results showed that vigorous stirring in the melt-pool was beneficial for forming an equiaxed crystal structure, achieving near-final shapes for both the metal sheet and microstructure. The chosen process demonstrated good consistency with experimental results.
