Magnetothermal finite element model of a new two-coil crucible induction furnace through the altair flux3d® software

  • 1 EPM-NM Laboratory – POLITEHNICA University of Bucharest, Romania

Abstract

A new two-coil cylindrical crucible induction furnace with the lateral coil connected to the one-phase electric power supply and the bottom coil connected to a capacitor bank with an appropriate value of the capacity is able to realize a desired balance between the diffusion of the power induced in the furnace bath through the lateral and the bottom faces of the crucible. Finite element magnetothermal model of the furnace is used to compute the temperature field, the thermal losses and the thermal efficiency associated with the furnace operation and to study three variants with the same bath volume of the new furnace related the diameter of the furnace bath,.
