INFLUENCE OF MOLTEN STEEL FLOW ON INCLUSI ON BEHAVIOR NEAR THE SOLIDIFICATION SHELL

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 st udies about the behavior of non-metallic inclusions near solidfied she ll under horizontal flow. In this study, a model experiment using wate r and particles made of ion-exchange resin is performed to analyze rel ations between behavior of non-metallic inclusions near solidified she ll and horizontal fluid. As a result of the model experiment, it is cl eared that the main factor avoiding non-metallic inclusion entrapment is the force given by the horizontal flow and that influence of Saffma n force can be negligible.
