Fused roller kiln 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 fused roller kiln with good thermal conductivity.
when it is used in the event of crystallization, will damage to become scrap, and fused roller kiln due to their small coefficient
of thermal conductivity, even if in the process of using it the fused silica ceramic roller’surface occurs crystallization,its
internal crystallization is very slow, products still can continue to use.
Fused roller kiln 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,kiln roller can be used as engineering
ceramic materials.
The preparation process and control
Fused roller kiln 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 fused roller kiln.Especially using vibration pressure grouting,this can methods can produce
OD130mmXL4700mm quartz ceramic roller products.
The principle of fused roller kiln 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.

The characteristics of fused roller kiln including:
1.small thermal expansion coefficient, good thermal shock resistance, good
volume stability,between 1000C and cold water cycle,the fused roller kiln can not be damaged;
2,Fused roller kiln have low thermal conductivity, almost not change under 1100C, insulation performance is good;
3,Under 1100C the intensity increased with the rise of temperature significantly,at room temperature to 1100C,fused roller
kiln’intensity can be increased 33%,other oxide ceramics from room temperature to 1000C,it’s intensity reduces about 60%;
4,Fused roller kiln have good electrical insulation, room temperature resistivity is 1015 Ω.cm, dielectric constant and dielectric
loss tangent with the temperature increasing,the change is small;
5,Fused roller kiln have high temperature stability, easy to make big and special products and has good machine workability;
