Problems solved by technology

[0002] In glass tempering, the difficulty of flat tempering of thin glass is that the thickness of the glass is small. If the thin glass stays in the furnace for too long before reaching the optimum tempering temperature, it will be easily deformed and the flatness will exceed the standard; in addition, due to the heat conduction of the glass itself, The heat exchange between ...

Abstract

The invention discloses a 2.5 mm glass tempering process, which relates to the technical field of thin glass tempering. A heating zone roller way (2) is arranged at one side of a sheet loading roller way (1), a left air convection device (3) and a right air convection device (4) are respectively arranged at two sides of the heating zone roller way (2), a tempering cooling part (6) is arranged at the rear end of the heating zone roller way (2), a sound insulation room (7) is arranged at one side of the tempering cooling part (6), the other side of the tempering cooling part (6) is respectively provided with a quenching fan (5) and a cooling fan (8), the quenching fan (5) and the cooling fan (8) are respectively provided with a plurality of air nozzles (10), a sheet unloading zone roller way (9) is arranged at the rear end of the tempering cooling part (6); and the 2.5 mm glass tempering process is as follows: 1, sheet loading, 2, heating, 3, quenching, 4, cooling, 5, sheet unloading test, and 6 packaging. The2.5 mm glass tempering process can reduce the heating time, increase the air flow rate, make the temperature more uniform and guarantee the product quality and finished product rate.

Description

Technical field: [0001] The invention relates to the technical field of thin glass tempering, in particular to a 2.5 mm thick glass tempering equipment and a tempering process thereof. Background technique: [0002] In glass tempering, the difficulty of flat tempering of thin glass lies in the small thickness of the glass. If the thin glass stays in the furnace for too long before reaching the optimum tempering temperature, it will be easily deformed and the flatness will exceed the standard; in addition, due to the heat conduction of the glass itself, The heat exchange between the surface and the surrounding environment, the heat lost in a very short period of time from the end of heating to the beginning of rapid cooling leads to a large temperature drop, and it is difficult to establish a sufficient stable gradient along the thickness direction during cooling, resulting in uneven stress in the glass, so it is difficult to ensure Product quality and yield. Invention cont...
