摘要:
Glass furnace for heating and melting materials to be vitrified, in which furnace two molten glass recirculation loops are formed in the bath between a hotter central zone of the furnace and, respectively, the inlet (E) and the outlet (Y) which are at a lower temperature; the furnace comprises lateral cooling means (12a), (12b) so as to create or strengthen lateral secondary recirculation rolls (B2La), (B2Lb) of the glass.
摘要:
The invention relates to a glass furnace for heating and melting materials to be vitrified, in which two loops (B1, B2) for recirculating molten glass are formed in the bath between a hotter central area (I) of the furnace and the entrance and exit at a lower temperature, respectively. The furnace comprises a means (X) for slowing the flow of molten glass in the primary recirculation loop (B1).
