Abstract

PROCEDE PERMETTANT UN DEGAZAGE DU VERRE FONDU. IL COMPREND: A.L'INTRODUCTION EN CONTINU DE LA CHARGE DE VERRE AU SOMMET DE LA CHAMBRE 12, DE MANIERE A FORMER UNE NAPPE 34 REPOSANT SUR LE VERRE FONDU, B.L'ALIMENTATION EN ENERGIE ELECTRIQUE DES ELECTRODES DU NIVEAU INFERIEUR 30, 32, AVEC UNE PUISSANCE SUFFISANTE POUR FOURNIR DU VERRE FONDU EN TONDU EN CONTINU AU BAS DE LA CHAMBRE, ET C.L'ALIMENTATION EN ENERGIE ELECTRIQUE DES ELECTRODES DU NIVEAU SUPERIEUR 28, AVEC UNE PUISSANCE SUFFISANTE POUR CREER DES POINTS CHAUDS LOCALISES DANS LE VERRE FONDU DE MANIERE ADJACENTE AUX ELECTRODES ET PERMETTRE LA MONTEE DES BULLES DE GAZ 40, A TRAVERS LE VERRE, A L'EMPLACEMENT DES POINTS CHAUDS POUR QU'ELLES PUISSENT S'ECHAPPER A TRAVERS LA NAPPE DE CHARGE. APPLICATION A LA FABRICATION EN CONTINU DU VERRE.
