Effect of in-Mold Electromagnetic Stirring on Solidification and Inclusion Behavior

EasyChair Preprint 9089

Abstract

A three dimensional transient model of in-mold electromagnetic stirring in bloom continuous casting mold has been developed. Time-varying electromagnetic field has been coupled with fluid flow, solidification and inclusion tracking model to investigate the effect of electromagnetic stirring on solidification and non-metallic inclusion behavior. The realizable k-ε turbulence model and the enthalpy-porosity approach have been used to investigate the fluid flow and the solidification of liquid steel in the mold. The behavior of non-metallic inclusions is analyzed using the stochastic tracking model. Electromagnetic stirring inhibits initial solid shell formation at the mold wall and turns the liquid core at the strand's center into a liquid-solid interface mush. Analysis has also been done on the impact of inclusion size and density on the removal rate of non-metallic inclusions. The findings indicate that inclusion and solidification behavior is significantly influenced by in-mold EMS.
