Elevate Kiln Performance with Premium Reaction Sintered Silicon Carbide Roller Tubes

Ensure unmatched stability and efficiency in your high-temperature roller hearth kilns with our advanced reaction sintered silicon carbide (SiC) roller tubes. Engineered for demanding applications across ceramics, lithium battery production, and specialty materials processing, they deliver superior durability and consistent performance under extreme conditions.

Why Choose Our SiC Roller Tubes?

Exceptional High-Temperature Capability

• Withstands temperatures up to 1380 °C

• Unique strength retention — bending strength increases from 250 MPa at 20 °C to 280 MPa at 1200 °C

Extended Service Life & Reduced Maintenance

• Outstanding resistance to oxidation, wear, and acid/alkali corrosion

• Ultra-high surface hardness (≥2100 HV2) ensures superior abrasion resistance

Superior Process Stability & Product Uniformity

• Maintains dimensional stability under mechanical and thermal load

• High thermal conductivity (45 W/(m·K) at 1200 °C) enables uniform heat distribution

• Low thermal expansion (4.5×10⁻⁶ K⁻¹) minimizes thermal stress and deformation
