Analysis of Multiphysics Field in ESR Process with Three Electrodes

摘要

The electroslag remelting(ESR)furnaces with three –phase installation by delta or star connection are mainly used to produce the large or super large ingot.The electrical efficiency is significantly improved as the short circuiting through the molten slag.However,little is found about fundamental research on the electromagnetic field of the ESR system with three –phase installation.A three-dimensional(3D)finite element model was developed to simulate the current density,magnetic field,electromagnetic force,Joule heating and temperature field for a system of electrode,slag and ingot in the ESR system with three –phase installation.
