Product Description

What is alumina ceramic tube/roller?
Alumina Ceramic rollers are hi-tech advanced ceramic products made with patented cool isostatic pressing technique and over 50 years of professional manufacturing experience. It is a kind of refractory material in roller kiln, as the role of bearing and transmission in the furnace. The service temperature can up to 1400C.
With the development and production of ceramic, roller kiln is widely used in building sanitary ceramics, daily porcelain and specialty ceramics. The requirements of refractory material used in furnace are continuous improvement, especially for strength and high temperature mechanical properties of roller presented updated requirements.
Alumina ceramic rollers is the development trend for ceramic rollers, because they fully meet the various needs of ceramic tile production, with the other advantages which other ceramic roller cannot be of.

Technical parameters for alumina ceramic roller tube:
Al2O3 not less than 76%
Density (kg / dm3) not less than 2.7
Water absorption no more than 7.5%
Working temperature 1200˚С-1280˚С
Straightness: Length X≤0.07%

Technical features:
1. High hardness.
2. High heat resistance : Alumina ceramic has excellent thermal stability, which means that it is widely used in areas where resistance to high temperatures is essential.
3. Good wear resistance : Alumina ceramic is the material of choice for alumina wear parts.
4. High electrical resistivity : Alumina is an electrically insulating material.
5. High corrosion resistance : It is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.
