METHOD FOR MANUFACTURING SHEET GLASS

摘要

The present invention relates to a method for manufacturing sheet glass comprising melting a glass raw material to obtain molten glass, forming the molten glass into a sheet-shaped glass ribbon in a forming device, and then annealing the glass ribbon in an annealing device, the sheet glass comprising non-alkali glass, and SO2 and/or SO3 glass being supplied so the atmospheric concentration of SO2 and/or SO3 directly below the bottom surface of the glass ribbon is 500-20000 ppm for at least 30 seconds in a temperature range of Tst + 70°C to Tst − 50°C, where Tst°C is the strain point of the non-alkali glass.
