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.

Part of ceramic roller sizes:

Diameter (mm)	Length (mm)	Diameter (mm)	Length (mm)
65--75mm	3000--4820	40mm	2000--3500
60mm	2700--4800	36mm	2000--3300

42mm	2200--3800	25mm	1600--3100

The ceramic roller of the above sizes , we have available stocks. We can also custom cut shorter lengths to your specifications. Other sizes available on request.

Product features：

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.
