The invention discloses a method for preparing a tempered glass, the steps of which are as follows: 1) a step of feeding a flat glass sheet into a heating chamber through a roller conveyor, 2) a heating step, 3) a cooling step, and 4) a step of unloading the sheet; The heating chamber is divided into at least 4 sections, and a sealing door with a control device is installed at the inlet of the heating chamber and the outlet of each heating section; the overall heating temperature of the heating chamber is 290-720 ° C, distributed in each heating In the section; the temperature between the previous heating section and the latter heating section is trapezoidally increasing, the temperature difference is 100-150 ° C, the heating time of each section is 100-300 seconds respectively; the glass is unidirectionally unmoved forward with the roller lane The moving speed is 20-100 mm/sec; the cooling step uses a blower cooling device, and the cooling time is 180-600 seconds. The invention combines the improved heating, moving and cooling methods of the glass, and is suitable for tempering of ordinary and various coated glass, eliminating roller printing and reducing stress streaks, and the process is simple, convenient to operate, and easy to popularize and implement.
