  • Inductive edge heating device for hot working strip material and the like
    Patent number: 4627259
    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.

  • Induction coil
    Patent number: 4532398
    Abstract: An induction coil, preferably for an induction heater, comprises a working coil, an outer casing and an inner lead-through channel for the workpieces, such as rods or tubes, which are to be treated in the induction coil. The region of the outer casing closest to the working coil consists of a layer of a rubber-elastic compound outside which is arranged a concrete casing. Using a two-part outer casing of this kind avoids the use of asbestos which is increasingly suspect because of its health hazard.
