Definitions

  • FIGS. 5, 5A and 6 are enlarged cross-sec ⁇ tional views of the homogenizer used in the apparatus of FIG. 4;
  • the furnace must with ⁇ stand, the highest fining temperature necessary is for glass of pure silicon dioxide, 2600° to 3000° centi ⁇ grade,,with the working temperature being nearly 1800° centigrade. Soda lime glass, however, is fined at 1700° to 2100° and extruded at 700° to 1000° centi ⁇ grade.
  • the outside area of this type of furnace is typically one-fiftieth to one-five hundredth the size of the present production furnaces with equal pro ⁇ duction capacity. Thus the more efficient insulation of the. furnace effects a great savings in fuel costs.

Abstract

Four pour la fabrication de verre dans lequel les ingrédients sont transférés depuis une trémie (16) dans une chambre de fusion (12) et chauffés en présence d'un gaz sous pression fourni par une source (23) et servant à écraser les bulles présentes dans le matériau en fusion. La chambre est chauffée pour former du verre en fusion qui est transféré dans une deuxième chambre (14) pour l'extraction des bulles. Le verre en fusion s'écoule ensuite de la deuxième chambre au travers d'une ouverture de sortie (102), le débit étant commandé par le réglage de la température de la tuyère. Dans un deuxième mode de réalisation, un homogénéisateur (136) est prévu pour l'extraction des bulles du verre en fusion.
