DEVELOPING AN UNIVERSAL TFIH EQUIPMENT USING 3D EDDY-CURRENT FIELD COMPUTATION

The application of 3D FEM computation of quasistatic eddy current fiel d and its coupled thermal, force field in developing an universal Tran sverse Flux Induction Heating (TFIH) equipment used for heating thin s labs in Thin-Slab-Casting-Processes(TSCP) is described in this paper. The A+phi formulation with Coulomb Gauge is applied and the continuity condition of the current is verified. The ICCG method is used for sol ving the algebraic system of equations. Fourier's thermal conduction e quation for moving media is computed. The computed results are confirm ed by measurement at a TFIH equipment. By the arrangement optimization of the equipment for the required temperature distribution a concise optimal method named Orthogonal Experimental Design is applied.
