SiSiC Rollers

Introduction：
The material of siliconized silicon carbide has series of basic superiority and characteristic.Many products can be made from it such as beams,rollers,cooling air pipes,thermal couple protection tubes,temperature-measuring tubes,sealing parts,and special shaped parts.
The SISIC Rollers are oxidation resistance,high bending strength under high temperature,no deformation for a long application time.Service life is 10-15 times more than Alumina roller.
 
Features:
1.High strength.
2.Extreme hardness.
3.Wear resistance.
4.Good corrosion resistance.
5.Good thermal shock resistance.
6.High thermal conductivity,.
7.Low coefficient of thermal expansion. 

Application:
They can be made as perfect kiln-furniture for roller hearth kin in the field of domestic ceramics,sanitary ceramics,building ceramics,magnetic materials and new energy battery materials.
