The sintering temperature is above 1250℃ in roller kiln,so it needs kiln furnitures to support and transport the ceramic products under high temperature. Silicon carbide ceramic SiSiC ceramic rollers are the kiln furnitures that support and transport the ceramic products under high temperature,help to complete the entire firing process.So SiSiC ceramic rollers  is the important part for roller kiln,its quality directly affects the normal operation of the kiln and the yield and quality of the ceramic products.

The length of SiSiC ceramic rollers and SIC rod  determines the effective kiln width,roller roundness and straightness will affect the quality of the product sintering and operating rules,thermal shock resistance will affect the service life of silicon carbide roller rod and the factory’s production costs.The high temperature strength of the SiSiC ceramic rollers  is the basis for bearing product weight,while the refractoriness and high temperature load softening point of silicon carbide roller determine the max operation temperature of the roller kiln.
