Eddy current and temperature field computation in transverser flux induction heating equipment for galvanizing line

摘要

This paper describes the 3-D eddy current FEM computation of transverse flux inductors used for heating strip in galvanized steel productions. The adopted mathematical model consists of a differential equation system for the steady-state eddy current problem and a Fourier's thermal conduction equation for moved media. The finite element method is applied in conjunction with the Galerkin method. The simplifications and boundary conditions required for an efficient solution are discussed.
