Abstract (en)
[origin: EP0822733A1] A device is claimed for the induction heating of a metal product (1) defiling continuously in a protective atmosphere, comprising an induction system (4) and a sealed enclosure (3) that is thermally and electrically insulated and gas-tight, arranged around the defiling product (1) between the defiling product and the induction system (4). The induction system (4) incorporates at least one induction winding of a conducting material connected to a high frequency current generator (45) and extending around the defiling product (1) in a plane perpendicular to the direction of defilement (F) of the product (1). The sealed enclosure (7) is arranged inside the winding(s) of the induction system (4) and extends in the direction of defilement (F) upstream and downstream of the induction system (4) over a distance sufficient to create a zone traversed by the return induction flux.A thermal treatment installation incorporating this device is also claimed
