The electrode-slag bath-ingot system was studied, and a 3D quasi-steady state mathematical model was developed for simulating electroslag remelting(ESR) process. The commercial software ANSYS was applied to calculate the electromagnetic, flow and temperature fields in ESR system. The calculation results showed that the current is confined to the surface of electrode/ingot and the corner of electrode in slag bath. The flow field and temperature field are attributed to the effects of electromagnetic force and joule heating resulted from current density distribution and cooling condition. The metal pool depth and maximum mushy zone width increase with the melting rate. Under the conditions for this investigation, the minimum local solidification time (LST) corresponds to 700~800 kg/h melting rate.
