How to Determine the Heating Temperature of Automotive Glass Tempering Furnace?

Date of release:2019-05-27 Author:晶菱机械 Click:

       The application of glass tempering furnace is simple and easy to operate, but in use, attention should be paid to the setting of heating furnace temperature. The temperature of automobile glass tempering furnace should be set in a reasonable range, and can not be easily adjusted. The slight adjustment of temperature will have a great influence on the heating efficiency of glass. In actual production, if the glass outlet temperature needs to be adjusted, the more accurate glass temperature can be obtained by changing the heating time.

      The stress of glass should be completely eliminated. Residual stress in glass can not be completely eliminated. When tension stress is formed in the center of glass at the initial stage of quenching, it is easy to cause glass rupture. Glass temperature can not cause serious deformation of glass, so the furnace temperature of automotive glass tempering furnace can not be set too high. It is appropriate that the furnace temperature of automotive glass tempering furnace is 60-100 degree C higher than that of glass. Because the temperature of automobile glass tempering furnace equipment can not cause glass deformation, so the furnace temperature can not be set too high. Because glass absorbs infrared rays, the infrared wavelength should be within the absorption range of glass.

       According to the absorption spectra of glass, the radiation wavelength in the furnace is about 3.0 micron, and the corresponding furnace temperature is about 700 C. The temperature of forced convection furnace glass is suitable between 600 ~630 C, so the temperature of most radiation heating furnaces is set between 680 720 C. Considering the relationship between stress relief time and temperature in small tempering furnace and the formation of temperature gradient during quenching, the temperature of thin glass heating furnace is slightly higher than that of thick glass heating furnace.
