To protect any magnetic circuit of an inducing means and an electromagnetic induction heating apparatus by providing a gas sealing and vacuum sealing chamber with electrical insulation (in other words, transmissive against a magnetic flux) attached to a heat insulating shield.
The heat insulating gas sealing and vacuum sealing chamber for the induction heating apparatus is intended to be used in the apparatus for heating a product advancing inside the chamber by electromagnetic induction. It is characterized by that the chamber has a sheath formed by a gas sealing and vacuum sealing material with electrical insulation in a center part surrounded by at least the induction heating means, an inner side face of the sheath is protected by a matrix of tiles made of heat insulating material and a plurality of pipes cooled by a flow liquid, and a plurality of pipes are confined in the matrix of tiles.
