A continuous, high-temperature preheating plant for preheating flat semi-finished steel products has a conveying line suitable to transfer the flat semi-finished steel products from an inlet to an outlet of the continuous, high-temperature preheating plant, and a plurality of heating devices arranged along the conveying line to heat the semi-finished steel products from an inlet temperature to a predetermined final temperature. The plurality of heating devices has, arranged in sequence between the inlet and the outlet along the conveying line, a first induction furnace, a second induction furnace, and at least one electric resistance radiation furnace. The continuous, high-temperature preheating plant has a cutting apparatus suitable to cut a starting flat semi-finished steel product into a plurality of cut segments having a predetermined length less than a length of the starting flat semi-finished steel product. The cutting apparatus is arranged between the first induction furnace and the second induction furnace.

The invention provides a method for recycling electrodes, the method comprising inductively heating the electrodes for a time sufficient to delaminate active material from current collectors underlying the active material. The invented process utilizes high frequency induction heating, which is a form of noncontact heating generated by the application of an electromagnetic field. The invention also provides a system for separating active material from current collectors of electrodes, the system comprising a particle transport mechanism enclosed in a housing; a first entry port for inserting electrodes into the housing and a second entry port for removing electrode components from the housing; and an inductive energy applicator for heating primarily interfaces comprising surfaces of the active material and surfaces of the current collectors opposing those active material surfaces.

Provided is an induction heating device for a metal plate including: a first conductor member that faces at least one of a front surface or a back surface of the metal plate and that is disposed across the metal plate in a width direction; a second conductor member that is separated from the first conductor member by a first distance in a plate passing direction of the metal plate, that faces at least one of the front surface or the back surface of the metal plate, and that is disposed across the metal plate in the width direction; connecting members that connect the first conductor member and the second conductor member to each other at positions separated from width-directional end portions of the metal plate to form a primary closed circuit; and an AC power supply connected to the primary closed circuit, in which the first distance is larger than a sum of dimensions of the first conductor member and the second conductor member in the plate passing direction of the metal plate.

The invention relates to a device for inductively heating at least one workpiece, in particular a substantially strip-shaped workpiece, including at least one furnace housing; at least one inductor arrangement arranged within the furnace housing, the inductor arrangement being arranged at least partially in an inductor region of the furnace housing; at least one heating region for receiving process gas. The heating region being arranged within the furnace housing; and separating material for separating, in particular for thermally separating, the inductor region and the heating region. Furthermore, the invention relates to a method for inductively heating at least one workpiece.
