Zusammenfassung:	Enclosure impervious to gas and to vacuum for use in an electromagnetic induction heating device of a product moving within the said enclosure, characterised in that it contains a sheath (1) made of a material impervious to gas and to vacuum and providing thermal insulation, the inner faces of the said sheath being protected by a heat shield (2) composed of a matrix of tiles made from a thermally insulating material and a plurality of tubes (4) cooled by circulating a fluid, the tubes embedded in the said matrix of tiles. Application specific to a moving strip of stainless steel heated by electromagnetic induction in a protective atmosphere with high hydrogen content. Enceinte d'étanchéité au gaz et au vide destinée à être utilisée dans un dispositif de chauffage par induction électromagnétique d'un produit défilant à l'intérieur de ladite enceinte, caractérisée en ce qu'elle comporte un fourreau (1) formé d'un matériau étanche au gaz et au vide et électriquement isolant, les faces internes dudit fourreau étant protégées par un écran thermique (2) composé d'une matrice de pavés en matériau thermiquement isolant et d'une pluralité de tubes (4) refroidis par circulation d'un fluide, ces derniers étant emprisonnés dans ladite matrice de pavés. Application notamment au chauffage par induction électromagnétique, sous atmosphère protectrice à forte teneur en hydrogène, d'une bande défilante d'acier inoxydable.
