3D multifields FEM computation of transverse flux induction heating for moving-strips

The numerical and experimental studies on induction heating of continuously moving strips in transverse field are presented in this paper. The induced eddy current and its coupled thermal field in moving media is computed wit h FEM. The adopted mathematical model consists of a Fouriers thermal conduc tion equation and a set of differential equations, which describes the stea dy-state eddy current problem in a configuration comprising a magnetic vect or potential and an electrical scalar potential. The calculated results are in good agreement with the measurement.
