Embodiment 1
[0033] The mass percentage of the chemical composition is SiO 2 69% 、 Al 2 o 3 12%, MgO 4%, K 2 O 3%, Na 2 O 8%, CaO 2% melted aluminosilicate glass substrate enters the annealing kiln A zone (pre-annealing zone) through the roller table for pre-annealing, the outlet temperature of the annealing kiln A zone is controlled at 600 ° C; after annealing The glass substrate in area A of the kiln enters the chemical tempering box (that is, the online chemical tempering area). The length of the box is 5m. The temperature inside the box is controlled at 590-600°C by a thermocouple. The ratio is 1:1 KCl and KNO 3Mix the solution, keep warm in the tempering box for 1 to 3 minutes, and then enter the annealing kiln B area (annealing area) to complete the on-line chemical tempering during the annealing process of the glass substrate; after the on-line chemical tempering, the various performance indicators of the glass substrate have reached a higher level. levels, as shown in the tab...
