Problems solved by technology

[0004] Since the greater the temperature difference between the surface and center of the glass during quenching, the higher the tempering stress value will be, but the thinner the glass, the less likely it will be to form a large temperature difference between the surface and the center. Only by increasing the cooling intensity of quenching can the thin glass be made There is a large temperature difference between the surface and the center. The greater the cooling intensity of the quenching section, the greater the energy consumption of the fan required. The huge energy consumption discourages many manufacturers. Therefore, it is necessary to provide a low energy consumption that can physically temper thin glass. device and method

Abstract

The invention provides a method and device for toughening thin glass. The method comprises the following steps of: in the process that the heated thin glass is conveyed to a quenching device, compressed air cools the surface of the thin glass, the thin glass cooled by the compressed air enters the quenching device, and the quenching device further cools the thin glass. According to the invention,the heated thin glass is refrigerated by compressed air, so that the surface of the thin glass can be quickly cooled; then the thin glass enters the quenching device to be further cooled; due to the fact that the compressed air cools the thin glass before the thin glass is conveyed to the quenching device, deformation of the thin glass caused by the fact that the thin glass which is not cooled isconveyed to the quenching device can be avoided. Due to the fact that the thin glass can be cooled twice after passing through the compressed air and the quenching device, the thin glass can be heatedto a higher temperature in a heating device, and the tempering strength of the thin glass is higher.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a method and device for tempering thin glass. Background technique [0002] As tempered glass is more and more widely used in construction, automobiles, home appliances, electrical lighting and other fields, the lightweight of glass has become a major market trend. Therefore, the glass needs to be made thinner and thinner, and the thinner the glass, the more difficult it is to temper. The physical tempering of thin glass with a thickness less than or equal to 2.5mm has always been a technical difficulty in the glass industry. During the physical tempering process, the glass needs to be heated to a temperature close to softening, and then cooled by rapid cooling to form tempering stress. [0003] Existing devices for tempering thin glass generally include: a heating device and a quenching device. In the Chinese invention patent "A Glass Tempering Furnace and Glass Temper...
