Silicon Carbide SiSiC Rollers


Reaction Bonded Silicon carbide ceramic rollers

Reaction bonded Silicon Carbide (SiSiC) rollers are used for the high temperature sintering zone of roller hearth kilns. The rollers are the important kiln furniture for table wear porcelain, sanitary wear, construction ceramics, glasses and magnetic materials production, etc.



 

Reaction Bonded Silicon carbide ceramic rollers characteristics:

@Higher bearing resistance

@High temperature resistance up to 1500℃ 

@No deformation under high temperature

@Longer service life,display 10-15times operational life compared to alumina rollers
