GLASS REDRAW SYSTEM AND METHODS OF FORMING A THIN GLASS SHEET USING A GLASS REDRAW SYSTEM

摘要

A glass redraw system including a redraw furnace having a furnace enclosure with 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 an annealing zone positioned between the furnace outlet and the attenuation heating unit. The glass redraw system further including one or more thermal alteration gates coupled to the furnace enclosure and extending into the furnace channel between the attenuation heating unit and one of the preheating zone or the annealing zone to inhibit heat transfer along the furnace channel between the attenuation heating unit and the one of the preheating zone or the annealing zone.
