Description
SiC Wear-Resistant Castable
Material System & Positioning
SiC wear-resistant castable uses silicon carbide (SiC ≥50%) aggregate with bulk density 2.70 g/cm³ and service up to 1600℃. The extremely hard SiC aggregate gives outstanding wear and erosion resistance; high thermal conductivity helps slag crust adherence and self-protection. It is Henan Songrui's professional grade for aluminum cells and CFB boilers under high-temperature abrasion.
Key Performance
- Extreme hardness: superior wear/erosion life to ordinary corundum wear material.
- High thermal conductivity: promotes slag crust adherence and self-protection.
- Anti-oxidation design: additives slow high-temperature oxidation.
- High strength: CCS (110℃×24h) ≥80 MPa.
Applications
- Non-ferrous: aluminum cell sides/bottoms, aluminum melting furnace linings.
- Power Boilers: CFB cyclones, wear zones, refractory belts.
- Cement: calciner throats, cooler high-temperature wear zones.
- Waste-to-energy: slag outlets and high-temperature wear zones.
Selection Advice
SiC materials oxidize in oxidizing atmospheres at high temperature—avoid local overheating. Provide detailed service conditions to Henan Songrui's technical team for selection.
Installation & Maintenance
Control water strictly, vibrate fully, heat up per the dedicated curve; monitor temperature to prevent local overheating.
Quality Assurance
Henan Songrui New Refractory Materials Co., Ltd. (Xuanhua Town Industrial Park, Henan) is a 2024 Class A taxpayer and SRDI SME. For selection, quotation or installation guidance, contact Manager Zheng (17513376789 / 17513376789@163.com).

Typical Applications
SiC wear-resistant castable combines high-temperature performance and extreme wear resistance:
- Power Boilers: CFB cyclone body and cones, loop seals, ash discharge pipes.
- Non-ferrous: copper flash smelter reaction shaft cones, chutes and elbows, aluminum cell sides.
- Cement: calciner cones, kiln inlet wear zones.
- Waste-to-energy: above-grate wear zones, secondary combustion chambers.
- Advantage: service up to 1500℃, high SiC content, extreme wear and thermal shock resistance.
FAQs
Why is SiC castable so wear-resistant?
SiC aggregate hardness is second only to diamond (Mohs 9.5); with dense bonding it stays extremely wear-resistant at high temperature.
Temperature rating?
About 1500℃, for combined high temperature and wear like CFB cyclones.
SiC vs ordinary wear-resistant?
Choose SiC for >1300℃ or extreme erosion; ordinary wear-resistant suffices below 1300℃.
