[0002] A tempering furnace is a device that strengthens glass. Its main function is to significantly improve the strength and durability of glass through a specific process. Specifically, the tempering furnace heats ordinary glass to a temperature close to the softening point, and then quickly cools it to create a pressure difference between the surface and interior of the glass, thereby enhancing its impact resistance and weather resistance.

[0003] In order to adapt to the smooth transmission in high temperature environment, all transmission inside the tempering furnace body is carried out by quartz ceramic rollers. In the normal production process, there may be cases where the quartz ceramic rollers are broken due to internal defects of the ceramic rollers or other external reasons. The traditional treatment method requires the tempering furnace to be cooled down to room temperature for replacement, and then heated to the process temperature before resuming production.
