Abstract:
A flat glass tempering method and a flat glass tempering device using the method. The method comprises a step of heating flat glass in a heating furnace and a step of tempering in a tempering unit which is composed of conveying rollers and chiller, wherein a step of pre-setting a high-temperature softened glass plate discharged from the heating furnace is provided between the heating step and the tempering step; the pre-setting step is specifically carried out in the following way: pre-cooling the glass plate with gentle breeze before the glass plate is fed into the tempering unit, so that the rigidity of the glass plate is improved, wherein the pressure of the gentle breeze acting on the surface of the glass plate is smaller than that of cooling air acting on the surface of the glass plate in the tempering unit, and the pressure formed by the gentle breeze is small enough to avoid or reduce deformation of the glass plate, caused by air pressure, as much as possible.
