Field and temperature calculations in transverse flux inductive heating devices heating non-paramagnetic materials using surface impedance formulations for non-linear eddy-current problems

This paper presents the calculation of both the field and temperature distribution in thin moving non-paramagnetic sheets in transverse flux inductive heating devices (TFIH). The surface impedance formulation for non-linear materials is extended to this thin plate problem. The temperature distribution is obtained by solving Fourier's thermal conduction equation. In this non-linear coupled electromagneto-thermal problem the temperature dependencies of the B/H curve, the conductivity and the thermal conductivity are fully considered.
