Abstract
A device for induction heating a continuously moving metal product in a protective atmosphere includes an induction system. A non-metallic and gas-tight enclosure is disposed around the moving product, between the product and the induction system. Uses include an installation for continuous heat treatment of a moving product, such as a steel strip or wire, in a protective atmosphere, between a fast cooling chamber and an intermediate temperature maintaining chamber.
Claims13
A device for induction heating a metal product moving continuously in a protective atmosphere, comprising induction means and a thermally and electrically insulative gas-tight enclosure disposed around said moving product, between said product and said induction means, said induction means comprising at least one turn of a conductive material connected to a high-frequency current generator and extending around said moving product in a plane perpendicular to the direction of movement of said product, said gas-light enclosure being disposed within said at least one turn of said induction means and extending a distance equal to at least 200 mm upstream and downstream of said induction means in said direction of movement to create an area crossed by a return induction flux.
