Title:
GLASS SUBSTRATE PRODUCTION METHOD AND GLASS SUBSTRATE PRODUCTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/002626
Kind Code:
A1
Abstract:
When producing a glass substrate, after causing molten glass that has overflowed from the upper section of a molded body in the upper space of a molding furnace chamber that has been heated to flow down along both side surfaces of the molded body, the molten glass is caused to merge at the lower end of the molded body to create sheet glass to be conveyed, and thereafter, the sheet glass is cooled. At such time, the molten glass or the sheet glass is blocked from receiving heat from the upper space in parts with a shielding member in the width direction which is orthogonal to the conveyance direction of the molten glass or the glass sheet, thereby adjusting the temperature distribution of the molten glass or the sheet glass in the width direction.
