APPARATUS AND METHOD FOR PRODUCING HIGH-TRANSMISSION GLASS

摘要

PROBLEM TO BE SOLVED: To provide a compact apparatus that preferably forms molten glass.

SOLUTION: The apparatus 100 for producing high-transmission glass includes: a tank furnace 1 for melting a raw material of the high-transmission glass to produce the molten glass required for formation; and a forming device 20 for forming the molten glass discharged from a discharge port 3 of the tank furnace 1 into a plate shape. The tank furnace 1 includes: a heating region 5 for melting the raw material of the high-transmission glass by adding heat; a defoaming region 6 for maintaining a temperature of the molten glass at a predetermined temperature to vent a gas from the molten glass; and a cooling region 8 arranged near the discharge port 3, which cools the temperature of the molten glass to a formable temperature using a cooler 9.
