What are the main factors that lead to uneven heating in the glass tempering furnace?

Source: LandGlass  Attention: 36  Published: 2022-12-22

1. The fault of the heating element in the glass tempering furnace will cause it not to work properly, resulting in uneven heating in the glass tempering furnace.

2. Failure or inaccurate calibration of the thermocouple(temperature sensor) in the glass tempering furnace can also lead to uneven heating in the tempering furnace. 

3. The glass is placed unreasonably on the rollers. Since ceramic rollers are poor heat conductors, repetitive use of a certain area of the heating furnace will lead to temperature reduction in the area. In the meantime, the area of ceramic rollers not carrying glass will have a relatively higher temperature, resulting in temperature differences between the areas and uneven heating for the glass. 

4. Poor edge sealing of the heating furnace will cause more local heat loss at the edges of the heating furnace, resulting in uneven heating in the glass tempering furnace.
