Abstract (en)

[origin: WO2021115508A1] The invention relates to a cross-field induction heating device for the induction heating of metal strip in a rolling mill. The device has a top inductor and a bottom inductor between which the metal strip to be heated is arranged. Each inductor is divided into two partial induction loops arranged adjacently to one another, which are connected in series and fed antivalently, so that the direct current which is supplied separately is aligned in the opposite direction in the two partial induction loops. Particularly good control of the edge heating of the strip can be achieved in this way.
