As a kind of refractory kiln furniture, RBSIC/SISIC roller plays a bearing/conveying role and it is the core part in the roller kiln. It makes an important contribution to the energy conservation, products firing cycle shortening and automation of roller kiln production. High bearing strength&extreme hardness Excellent thermal shock resistance Corrosion resistance&wear resistance High temperature creep resistance 10 times operation life comparing to Alumina roller.
