Abstract

L'enceinte de la poche est constituée, dans la zone de chauffage, par des tirants métalliques longitudinaux 1, séparés par des joints réfractaires isolants électriques 2, et maintenus en position par serrage entre deux brides annulaires métalliques, inférieure 8 et supérieure 6, solidaires respectivement du fond de poche 9 et de la virole métallique 7 disposée au voisinage de extrémité supérieure de la poche. Cette virole 7, le fond de poche 9 ainsi que leurs brides annulaires respectives 6 et 8 sont découpées suivant un plan radial à l'enceinte et du matériau réfractaire isolant de 1'électricité est inséré dans les interstices 23 et 24 ainsi réalisés. Ces dispositions permettent de réduire au minimum l'échauffement de l'enceinte par circulation de courants de Foucault indésirables. La poche selon l'invention sert pour tout traitement inductif d'une charge métallique : fusion, maintien ou montée en température en phase liquide.
