Product Description

Application:
Fused silica ceramic roller is ideal substitute for graphite rolls and ceramic coating rolls, prevent oxidation and dross build-up, carrying and transmitting glass in glass horizontal tempering furnace and annealing kilns.
Brief Introduction:
Fused silica ceramic roller adopts fined high purity fused silica as raw material and made by foreign advanced grouting molding technique and processing manufacturing line. Molding methods mainly are grouting and gel injection molding, dry pressing and cold isostatic pressing. We can produce big size of fused silica ceramic roller by these methods.There are end caps and end shafts, usually made of metal, tightly connected at both ends of ceramic rolls.In the solar energy industry, the service temperature is about 1150C. In glass industry, the Service temperature: about 900C.
Advantages:
1. Raw material with high purity, excellent chemical and physical properties 2. Good surface smoothness, not easy to scratch glass 3. High density without bubbles 4. Very High Compressive Strength, Flexural Strength & Impact Strength at high temperature. 5. Good wear resistance 6. Small radial beat (run) 7. Very low thermal expansion coefficient 8. Strong thermal shock stability 9. High precision in size 10. No deformation under high temperature 11. Long service life, The reliable axle neck joint technology(anti-loose technology) 12. No pollution to glass 13. High economic efficiency, can reduce the overall cost of belt conveyer, reduce maintenance working hours
