Ceramic Roller Tube With Refractory Heat Temperature Alumina Ceramic Roller
As a Professional Advanced Technology Ceramic Manufacturers,
Us Support To Customize Different Specifications Of Ceramic Components
Ceramic roller is produced by technical ceramics such as Alumina Oxide (Al2O3),Silicon Nitride (Si3N4), Zirconium Oxide (ZrO2) or Silicon carbide (SiC)... etc. which is suitable for the production of daily porcelain in the roller kiln and electric furnace.
Ceramic roller has excellent bending strength at high temperatures, products for fire within 1750 ℃ (extremely reliable thermal stability and excellent thermal shock performance.
Alumina ceramic roller is an essential component of modern high temperature roller kilns.
Ceramic roller is a kind of high temperature and high strength, high hardness, wear resistance, corrosion resistance and can be self lubrication of high temperature ceramics, using temperature as high as 1750 ℃, with excellent corrosion resistance, except hydrofluoric acid, and other kinds of acid corrosion, and alkali resistance, all kinds of metal corrosion, and it has excellent electrical insulation and radiation resistance.

1. The hardness
Alumina ceramic roller rockwell hardness of hra80-90, hardness is second only to diamond, far more than the wear resistance of steel and stainless steel.
2. Excellent wear resistance
Wear resistance is 266 times that of manganese steel and 171.5 times that of high chromium cast iron.Under the same working condition, the service life of the equipment can be extended by at least 10 times.
3. Light weight
Its density is 3.6g/cm3, only half of the steel, which can greatly reduce the load of equipment.
Ceramic materials:
· 95%--99.99% Alumina (Al2O3) · Silicon Carbide · Silicon Nitride
· TTZ: Magnesia partially stabilized Zirconia (ZrO2) · YTZP: Yttria partially stabilized Zirconia (ZrO2)
