Optimal design of transverse flux induction heaters for thin strip

Transverse flux induction is an advantageous possibility to heat thin metal strip. This technology allows to reach high electrical efficiencies and hi gh power densities, which lead to small necessary floor space and shout hea ting time. The successful industrial application of these heaters requires the solution of the complicated design. Therefore, a concept for the optima l design of transverse flux induction heaters has been developed. It is bas ed on the combination of already existing experts know-how, numerical simul ation programs and mathematical optimisation methods. In this paper the suc cessful use of the concept is presented referring to the design of an indus trial transverse flux induction heater for brass strip.
