High-Performance Silicon Carbide (SSiC) Rollers for Roller Hearth Kilns
Enhanced Thermal Efficiency & Durability
Our pressureless sintered silicon carbide (SSiC) rollers are engineered specifically for the demanding environment of roller hearth kilns. They serve as the core refractory component, delivering unmatched high-temperature performance, superior thermal conductivity, and exceptional mechanical strength to maximize your kiln's productivity, energy efficiency, and product quality in continuous, high-throughput operations.
Key Features & Benefits
Exceptional High-Temperature Stability: Withstands continuous operation at temperatures up to 1650°C in air, maintaining structural integrity and preventing deformation.
Superior Thermal Conductivity & Shock Resistance: Excellent heat transfer (196 W/m*K at 20°C) ensures uniform temperature distribution, while a thermal shock resistance >350°C prevents cracking during rapid temperature cycles.
High Mechanical Strength & Wear Resistance: A high flexural strength (320-400 MPa) and extreme hardness (2350 HV) guarantee a long service life under heavy loads and abrasive conditions.
Optimized for Efficiency: The combination of high thermal conductivity and low porosity (≈0%) translates to faster heating rates, reduced energy consumption, and consistent product quality.
