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.
The preparation process and control
Ceramic roller for glass tempering furnace basic process includes powder processing, forming, sintering and machining.
Molding methods are mainly grouting and gel injection molding, dry pressing and cold isostatic pressing molding. Using these methods can produce big size of ceramic roller for glass tempering furnace.
Especially using vibration pressure grouting,this can methods can produce OD130mmXL4700mm quartz ceramic roller for glass tempering furnace products.
The principle of ceramic roller for glass tempering furnace firing two points:
1,to ensure that the strength of the products after firing enough;
2,control products’crystallization and deformation,produce a small amount of cristobalite devitrified (<3%) not obviously influence on the material performance.
