Influence of Molten Steel Flow on Inclusion Behavior near the Solidification Shell

Abstract

In in-mold electromagnetic stirring (EMS), horizontal flow is generated by Lorenz force so that non-metallic inclusion entrapment is avoided. Though the effect of EMS is popular by many reports, there are few studies about the behavior of non-metallic inclusions near solidfied shell under horizontal flow. In this study, a model experiment using water and particles made of ion-exchange resin is performed to analyze relations between behavior of non-metallic inclusions near solidified shell and horizontal fluid. As a result of the model experiment, it is cleared that the main factor avoiding nonmetallic inclusion entrapment is the force given by the horizontal flow and that influence of Saffman force can be negligible.
