Methods of forming thin glass sheets using glass lead low system and glass lead low system

摘要

The glass reed-low system comprises a furnace enclosure having a furnace channel extending between a furnace inlet and a furnace outlet, an attenuation heating unit coupled to the furnace enclosure, a preheating zone positioned between the furnace inlet and the attenuation heating unit, And a lead-lower furnace having an annealing region located between the furnace outlet and the attenuation heating unit. Wherein the glass lead-low system is coupled to the furnace enclosure and is operatively connected to the preheating zone or the annealing zone to suppress heat transfer along the furnace channel between one of the preheating zone or the annealing zone and the attenuation zone. And one or more column change gates extending into the furnace channel between one and the attenuation heating region.;
