FIELD: electrical engineering.
SUBSTANCE: proposed inductive heating device for heating a moveable metallic plate comprises an induction coil encircling the metal plate. The induction coil comprises a top part, meant for placing above the metal plate, and a bottom part, meant for placing below the metal plate. The top and bottom parts of the induction coil are separated from each other longitudinally by the metal plate in at least one position in the transverse direction of the metal plate. The distance in the longitudinal direction of the metal plate between the top and bottom part of the induction coil varies in the transverse direction of the metal plate. Part of the induction coil, where the top and bottom parts intersect, is located on the edge or beyond the metal plate in the transverse direction.
EFFECT: invention provides for more uniform distribution of temperature along the width of the plate.
