The Refractory Reaction Bonded Silicon Carbide Ceramic (RBSIC or SiSiC) Rollers have excellent high temperature bearing capacity and there are no deformations even in very high temperature. The rollers display more than 10 times of operational life compared to the alumina rollers. They are used for the high temperature sintering zone of roller kilns for production of the daily-used ceramics, sanitary ceramics, building ceramics, glass and magnetic materials.
