RSiC Ceramic Rollers


Recrystallized Silicon carbide (RSiC) ceramic rollers

Recrystallized Silicon carbide (RSiC) ceramic 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.


 Characteristics:

@Higher bearing resistance

@High energy efficiency

@High temperature resistance up to 1650℃ 

@No deformation under high temperature

@Longer service life
