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.Thereareendcapsandendshafts,usuallymadeofmetal,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 properties2.Good surface smoothness,not easy to scratch glass3.High density withoutbubbles4.Very High Compressive Strength, Flexural Strength & Impact Strength at high temperature.5. Good wear resistance6. Small radial beat (run)7. Very low thermal expansion coefficient8. Strong thermal shock stability9. High precision in size10. No deformation under high temperature11. Long service life, The reliable axle neck joint technology(anti-loose technology)12. No pollution to glass13. High economic efficiency, can reduce the overall cost of belt conveyer, reduce maintenance working hoursDescriptionIndexDescriptionIndexRaw MaterialFused SilicaCompression strength≥ 60(MPa)Purity≥99.8%Transverse strength≥30(Mpa)Bulk Density≥1.98 g/cm3Radial Beat≤0.10mmApparent Porosity7-11%Press Compression102 MpaExpasion Coefficient≤0.6(x10-6/ºC)Chemical CompositionSiO2Surface Roughness≤1.6umShapeRound, hollow, etcOD Tolerance±0.05mmPorosity10%T.I.R.
