Gastight and vacuum-tight chamber intended to be used in a device for heating a product advancing inside the chamber by electromagnetic induction, characterized in that it comprises a gastight and vacuum-tight sheath made of an electrically insulating, gastight and vacuum-tight material, the inner faces of the sheath being protected by a heat shield consisting of a matrix of tiles made of a thermally insulating material and of a plurality of tubes cooled by the flow of a fluid, the latter being trapped in the matrix of tiles.

Vacuum and gas tight enclosure for induction heating system

A heating device for the electromagnetic induction heating of a metal strip traveling in a specified direction. The device includes at least one electric coil arranged opposite at least one of the large surfaces of the strip so as to heat the latter by transverse magnetic flux induction, each coil being associated with at least one magnetic circuit. Each circuit is divided into a plurality of magnetically independent bars arranged parallel to the direction of travel of the strip. The bars may moved toward or away one another thereby adapting to the width of the strip and distributing the magnetic flux across the width of the strip.
