ELECTRIC INDUCTION HEAT TREATMENT OF ELECTRICALLY CONDUCTIVE THIN STRIP MATERIAL

摘要

Apparatus and method are provided for electric induction heat treatment of electrically conductive thin strip material. Multiple series-connected coil loops, each having a pole pair, are provided in each of a top and bottom induction coil, which are positioned mirror image to each other. The top and bottom induction coils form a transverse flux induction heat treatment apparatus. A separate flux concentrator is provided over and on the side of each pole. The thin strip material passes between the poles of the top and bottom induction coils and the flux concentrators associated with each of the poles.
