The Refractory Reaction Bonded Silicon Carbide (RBSIC or SiSiC) Kiln Car Structure Components has excellent bending strength in high temperature, good oxidation resistance, and strong abrasion resistance, no breaing and bending after long time using. It can be applicated to the high temperature sintering zone of roller kilns for daily-used ceramics, and the bearing beams for tunnel kilns, shuttle kilns, double roller kilns and other industrial kilns.
