Abstract: A device achieves thermal protection and cooling of the poles of an electromagnetic inductor, in particular for an induction furnace. The furnace comprises a plurality of tubes, arranged side by side and substantially coplanar, through which a coolant fluid flows. The connection of the tubes to the inlet and outlet pipes for the coolant fluid is made by a combination of socket and O-rings designed to ensure both electrical discontinuity and leaktightness between each tube and the pipes.

Abstract: Electromagnetic-induction heating coil, especially for the heating of metallurgical products, in which coil conductors are cooled with the aid of a tube in which a cooling fluid, in thermal contact with the conductors, circulates, wherein the conductors are wound in at least one ply, as a helix around the cooling tube so that the ply has at least one twist of one complete turn between two electrical terminals of the coil.

Abstract: Device for the induction heating of flat metallic products on the move with the aid of electrical coils provided on magnetic armatures arranged on either side of the large faces of the product to be heated, which moves continuously between the said coils, wherein the inductors are mechanically independent of each other and they are arranged symmetrically in relation to the median plane of the product so that the magnetic fields generated are in phase opposition, leading to a ring-like distribution of the currents induced in the product to be heated up.

Abstract: Mobile modules for electromagnetic-induction heating or reheating a flat metallurgical product on the move, wherein each of the said modules is mounted so as to move on a track perpendicular to the direction of movement of the product. Each module includes an on-board counterweight, the potential energy of which may, at any instant, be used to quickly remove the module from the product.
