A 3D finite element model has been developed to analyze the AC electromagnetic field and Joule heating field in three-phase electroslag remelting(ESR)processes with three and six electrodes using Maxwell equations and Joule law,and then transient temperature field is calculated by sequential coupling with heat conducting equation.Numerical results show that the maximum of current density is distributed on the surfaces of ingot as the result of skin effect,and concentrated at electrode tips in slag cap.The Joule heat mainly appears in slag and the maximum appears at the interface of electrode/slag.The maximum temperature appears under the electrode,in the middle of the molten slag.Temperature distribution at the slag/metal interface is relatively uniform.The depth of the matel pool is about equal to the radius of ingot.Simulated temperature field is compared with experiment and obtained a good agreement.

Numerical results show that the maximum of current density is distributed on the surfaces of ingot as the result of skin effect, and concentrated at electrode tips in slag cap. The Joule heat primary appears in slag and the maximum appears at the interface of electrode / slag.The maximum temperature appears under the electrode, in the middle of the molten slag. Temperature distribution at the slag / metal interface is relatively uniform. The depth of the matel pool is about equal to the radius of ingot. Simulated temperature field is compared with experiment and obtained a good agreement.
