Ceramic roller for glass tempering furnace not only have the same properties like quartz glass: small thermal expansion coefficient, good thermal stability, good electrical insulation, good resistance to chemical attack, but also has the nature of their lack of quartz glass products, such as ceramic roller for glass tempering furnace with good thermal conductivity.
when it is used in the event of crystallization, will damage to become scrap,and ceramic roller for glass tempering furnace due to their small coefficient of thermal conductivity, even if in the process of using it the ceramic roller for glass tempering furnace' surface occurs crystallization.
Ceramic roller for glass tempering furnace have one of the biggest advantages:under 1100C the intensity increased with the rise of temperature significantly,at room temperature to 1100 c,its intensity can be increased 33%, therefore,ceramic roller for glass tempering furnace can be used as engineering ceramic materials.
