Convection tempering furnace manufacturers believe that glass tempering is a process of heating and rapidly cooling glass to improve its mechanical properties. The principle is that after the glass is heated, the cooling technology makes the glass itself have sufficient tensile stress, and the corresponding compressive stress is generated on the entire surface. The tempering process effectively achieves the safety, high strength, and thermal stability required by the glass, and can meet daily needs. There are two methods for glass tempering: physical tempering and chemical tempering. First, the principle of physical tempering is to heat the glass material through a heat transfer medium and rapidly cool it in a cooling medium. Depending on the different media, the methods can be divided into the following categories:
1) Gas medium tempering method: Convection tempering furnace manufacturers believe that the so-called gas medium generally uses air as the heat transfer medium. At this time, the tempering furnace needs to reach a temperature of 600-700. Then, air is blown to cool the glass. Although this cooling method greatly reduces the cooling cost, it also ensures that the human body is not harmed. However, the cooling speed is slow, the cooling efficiency is low, and it is easy to cause glass deformation.
2) Liquid medium tempering method: As the name suggests, the liquid interpretation tempering method uses liquid to temper and cool the heated glass.
3) Granular tempering method: Convection tempering furnace manufacturers believe that using smaller particles of alumina to cool the heated and softened glass. This method has a good cooling effect, and the tempered glass is of high quality, but the relative cost is also high.
Convection tempering furnace manufacturers believe that in addition to physical methods, there is also a chemical toughening method. This method mainly changes the surface composition of the glass through chemical methods, increases the compressive stress of the glass, and improves the mechanical properties of the glass. Glass tempered by this method is not easy to deform and is of good quality. However, its efficiency is low and the cost is high.
Convection tempering furnace manufacturers believe that with the improvement of technology level, glass tempering technology has developed rapidly. At present, tunnel-type tempering furnaces are widely used. This type of tempering furnace is widely popular because of its high utilization efficiency and ability to heat larger glass. The tempering furnace mainly consists of a front loading platform, a heating zone, a tempering and cooling zone, an unloading platform, an operating platform, and an electrical control device. The heating method mainly adopts the form of full-electric radiation heating, that is, the heat source mainly comes from the electric heating elements in the furnace. Therefore, it is necessary to control the distance between the electric heating elements and the glass plate to be heated, otherwise, heat and energy will be easily wasted.
Convection tempering furnace manufacturers believe that the application of multi-station heating technology can not only achieve significant energy-saving effects but also greatly avoid the phenomenon of tempering furnace explosions. The so-called glass tempering furnace station refers to the fact that glass of the same specification swings back and forth in its respective areas along the length direction of the furnace body, completes the predetermined time in its respective areas, and after the glass is heated to the corresponding requirements, it is moved to the next station. Although the manufacturing processes and structures of various tempering furnaces are different, the temperatures required for heating and discharging glass are almost the same. For multi-station tempering furnaces, the temperature difference in the furnace can be greatly reduced, preventing glass cracking in the tempering furnace, reducing heat loss, and playing a significant role in energy saving and emission reduction.

Features of tempering furnaces, explained by a convection tempering furnace manufacturer
Manufacturers of convection tempering furnaces believe that with the development of various industries, the uses of tempered glass are becoming increasingly widespread, making it an indispensable material in life. Tempering furnaces are important equipment in glass processing. A glass tempering furnace is a device that heats and then rapidly cools glass, causing compressive stress to form on the surface of the cooled glass and tensile stress inside, thereby increasing the strength of the glass and transforming ordinary annealed glass into tempered glass.
