Abstract
An edge-region heating device for use in the hot rolling of metallic strip after some cooling of the strip has occurred, employs an induction heater to preferentially raise the temperature of the edge-regions of the strip to compensate for the faster cooling of these edge regions whereby a more uniform temperature is obtained over the cross-section of the strip when a later hot rolling operation is performed.
