Product Overview
This high-performance silicon carbide roller is manufactured using advanced pressureless sintering technology. Made from high-purity SiC, it delivers exceptional mechanical strength, outstanding high-temperature resistance (up to 1650°C in oxidizing atmospheres), excellent corrosion resistance, and superior thermal shock performance. Designed specifically for demanding industrial applications such as roller hearth kilns, it ensures reliable and stable operation under extreme thermal conditions. Custom dimensions and end-processing services are available to meet precise customer requirements.
Typical Applications
- Conveying rollers in high-temperature roller kilns
- Suitable for industries including:
- Daily porcelain & sanitary ceramics
- Lithium-battery raw-material production
- Magnetic materials
- Other high-temperature firing zones in roller kilns
Key Features
- Exceptional Wear Resistance
- Excellent Oxidation Resistance
- Outstanding Corrosion Resistance
