  • the molten glass flowing into the fining tank from the transfer tube is the top of the inner surface of the transfer tube and the tubular portion. It can flow along the top of the inner surface of the container without staying. Therefore, the gas generated from the molten glass can move in the refining tank as the molten glass flows after it floats. Therefore, it is possible to prevent the occurrence of gas accumulation.

Abstract

L'invention concerne un procédé de fabrication d'un article en verre, ledit procédé comprenant : une étape de fusion thermique d'un matériau de verre dans une cuve de fusion pour donner un verre fondu GM ; une étape de transfert du verre fondu GM, qui s'écoule hors d'une sortie (1a) de la cuve de fusion (1), par une conduite de transfert (10) ; et une étape de remplissage du verre fondu GM, qui est transféré depuis la conduite de transfert (10), dans une partie tubulaire (7) d'une cuve d'affinage (2), puis d'affinage du verre fondu GM dans cet état. La conduite de transfert (10) comprend une extrémité côté amont (10a) destinée à être reliée à la cuve de fusion (1) et une extrémité côté aval (10b) destinée à être reliée à la partie tubulaire (7). La conduite de transfert (10) est reliée à la partie tubulaire (7) de telle sorte que la partie supérieure intérieure (11a) au niveau de l'extrémité côté aval (10b) coïncide avec la partie supérieure intérieure (7b) de la partie tubulaire (7).
