Abstract
Apparatus and method for electromagnetic heating of a roll by induction, in which a variable magnetic flux is directed into an outer surface of the roll from a magnetic shoe device comprising a plurality of cores situated externally of the roll and over substantially the entire axial length thereof. Each core is spaced a discrete distance from the roll surface. The magnetic flux acts to induce eddy currents along the surface of the roll, thus generating heat thereon.
