Kinetics Evaluation of Inclusions Removal during Levitation Melting of Steel in Cold Crucible

Abstract

Transport phenomena of inclusions during levitation melting of steel samples in a cold crucible are discussed by use of numerical simulation. Taking account of various forces acting on the inclusions during fusion, population balance simulation is performed within the framework of finite volume method (FVM) analysis for magnetohydrodynamics (MHD). The numerical results supported the experimental results that the inclusions size distribution does not change so much due to the agglomeration effect and the phenomena of inclusions removal to the sample surface are mainly caused by the electromagnetic reaction force and the flotation.
