ABSTRACT:
An induction heater, particularly for heating metal slabs, is constructed in modular form. Two sets of modules are spaced apart to form a gap for reception of a slab. Each module is slotted and is wound with a group of polyphase coils so as to produce a travelling wave magnetic field and each group of coils is connected to a polyphase electrical supply independently of the other groups. The modules of one set are disposed directly opposite modules of the other set so that each pair of confronting modules have their like poles in opposition.
