Definitions

  • the twill 322 adjusts the flow rate of the molten glass 12.
  • the twill 322 can move up and down with respect to the lip 324 forming the flow path of the molten glass 12 and is inserted into the flow path of the molten glass 12 to adjust the opening degree of the flow path of the molten glass 12.
  • the cross-sectional shape of the lower surface of the twill 322 may be a curved shape convex downward.
  • support grooves 348a and 350a for supporting the limiting wall 328 may be provided in the left side wall 348 of the spout space S1 and the right side wall 350 of the spout space S1, respectively.
  • the support grooves 348 a and 350 a restrict the movement of the limiting wall 328 in the flow direction of the molten glass 12. Therefore, for example, when the limiting wall 328 is split in half at the center in the left-right direction (the center in the vertical direction in FIG. 3), the broken pieces can support each other and can be prevented from falling onto the molten glass 12.

Abstract

L'invention porte sur un procédé pour la fabrication d'une plaque en verre qui, après avoir amené du verre fondu (12) à passer dans une porte d'ouvreau (322) qui règle le débit du verre fondu (12), apporte en continu le verre fondu (12) par une lèvre (324) qui forme un trajet d'écoulement à cet effet sur de l'étain fondu (16) à l'intérieur d'une cuve de fusion d'étain (310), ce qui forme une forme de plaque par le fait d'amener celui-ci à s'écouler sur le dessus de l'étain fondu (16). Une paroi de limitation (328) qui limite le mouvement de gaz est disposée au-dessus du verre fondu (12) dans un espace de goulotte (S1). Du gaz empêchant l'oxydation est introduit dans un premier espace (S11) formé par la porte d'ouvreau (322), la paroi de limitation (328) et le verre fondu (12) et du gaz empêchant l'oxydation est introduit dans un second espace (S12) formé par la paroi de limitation (328), une paroi de séparation (326) et le verre fondu (12). Le gaz empêchant l'oxydation introduit dans le premier espace (S11) et le gaz empêchant l'oxydation introduit dans le second espace (S12) sont différents.
