What effects do the ceramic rollers in the furnace have on the flatness of tempered glass?

Source: LandGlass  Attention: 535  Published: 2020-02-28

The repeated use and cleaning of the ceramic rollers over time inevitably lead to wear, especially when sanding is required to remove some tough deposits on the rollers. To heat the glass on the rollers with an uneven surface or out of roundness to the transition temperature will certainly result in deformation.

Although the ceramic rollers used in the glass tempering furnace have superior thermal stability and high resistance to thermal shock, the possible unevenness of its internal structure may also lead to deformation under high temperatures. The thermal deformation of rollers will cause the ceramic roller bed to bend, leading to the deformation of glass conveyed on the roller surface.
