Use of induction transverse-flux heating for flat material

Extensive numerical parameter studies have taken place at the Institute for Electroheat of the University of Hanover to analyse the influences of the numerous operating and plant-related parameters on the process of induction heating in a magnetic transverse field. The knowledge gained has served as a basis to develop initial design criteria for transverse-flux heating sys tems. Besides the optimisation of the electrical efficiency and of the temp erature distribution in the strip, parasitic mechanical influences also fin d consideration for the first time. The thermal deformation of the strip an d the resulting effects on the temperature field, as well as the generation of noise, receive special attention.
