Silicon carbide radiant tube
Silicon carbide products are the most suitable kiln furnitures of tunnel kilns, shuttle kilns, roller of hearth kilns as the flame tubes.
With high temperature thermal conductivity, good, quick cooling in heat resistance, resistance to oxidation, thermal shock resistance of good, long life.
Features:
• Excellent energy savings.
• Lighter weight and higher load capacity.
• Excellent distortion resistance at high temperature.
• High thermal conductivity
• High Young’s modulus
• Low thermal expansion coefficient
• Extremely high hardness
• Wear resistant
Application:
• sanitary ware
• Kiln furniture crucibles
• glass panel industries
• Sliding bearings
• glost firing of tableware.
• Heat exchangers
• Burners
• Wear parts (thread guides)
RBSiC(SiSiC) nozzles are used for the high temperature systems of tunnel kilns,shuttle kilns and many
other industrial kilns. RBSiC(SiSiC)cross beams have higher strength and there are no deformations even in very high temperature.

RBSiC(SiSiC) nozzles/beams/ rollers are used for the loading structure systems of tunnel kilns,shuttle kilns and many
other industrial kilns. RBSiC(SiSiC)cross beams have higher strength and there are no deformations even in very high temperature.
And also the beams display long operational life.The beams are the most suitable kiln furniture for sanitarywear and electrical porcelain applications. RBSiC(SiSiC)has excellent thermal conductivity, so it is available to save energy with less weight of the kiln car.
