The tempering furnace is suitable for the production of high-quality, ultra-thin, ultra-small standard or super-large standard flat tempered glass such as high-end industrial surfaces, household appliances, lamps and lanterns, building decoration, and tempered lamination.Influence of Brazing Vacuum Degree on Copper and Hafnium Brazed Joints First, the working principle of the tempering furnace: 1. Physical method The glass tempering equipment heats the flat glass and then quenches it, so that the surface layer of the cooled glass forms compressive stress and the inside of the glass forms tensile stress, so as to improve the strength of the glass and make ordinary annealed glass into tempered glass device of. Since this tempering method does not change the chemical composition of the glass, it is called physical glass tempering equipment.Valve body vacuum heat treatment 2. Chemical tempering equipment improves the strength of glass by changing the chemical composition of the glass surface. At present, there are methods such as surface dealkalization and alkali metal ion exchange. Because this tempering method changes the chemical composition of the glass, it is called chemical method glass. Tempering equipment.Oil cooler vacuum brazing
