Key Features and Benefits
1. Superior Thermal Insulation Performance
- Ultra-low thermal conductivity (0.35-0.55 W/m·K at 1000°C)
- Reduced heat storage capacity enables faster furnace heating/cooling cycles
- Energy savings up to 30% compared to conventional refractory bricks
- Maintains consistent thermal properties even after prolonged high-temperature exposure
2. Excellent Thermal Stability
- Low linear shrinkage (<1.0%) at maximum service temperature
- Withstands rapid temperature fluctuations (30+ thermal shock cycles)
- Maintains dimensional stability in reducing/oxidizing atmospheres
- High refractoriness under load (1500°C+ for 0.2MPa deformation)
3. Optimized Mechanical Properties
- Cold crushing strength 15-40 MPa (adjustable based on density requirements)
- High abrasion resistance for long service life
- Minimal dust generation during handling and installation
- Easy cutting and shaping for precise furnace lining
4. Chemical Resistance
- Excellent resistance to alkali and acid slag erosion
- Low iron content (<0.8%) prevents contamination in sensitive processes
- Stable performance in CO and H₂ atmospheres
- Non-wetting characteristics with most molten metals
