1. Overview & Key Benefits
Fireproof bricks for sale (refractory bricks) are heat-resistant materials designed to withstand temperatures from 800°C to 1,800°C, making them essential for furnaces, kilns, fireplaces, and industrial boilers. Kerui Refractory, an ISO 9001-certified manufacturer, offers premium fireproof bricks tailored for extreme thermal and mechanical demands. Key advantages include:
- Energy Efficiency: Low thermal conductivity (0.5–1.5 W/m·K) reduces heat loss.
- Longevity: 2–5x lifespan vs. conventional materials in high-abrasion environments.
- Versatility: Custom sizes/shapes for unique project requirements.
2. Technical Specifications
2.1 Material Grades & Performance
| Grade | Al₂O₃ Content | Max Temp | CCS | Porosity | Thermal Shock Resistance |
|---|---|---|---|---|---|
| Standard Fireclay | 25–35% | 1,300°C | 20–35 MPa | 18–25% | >15 cycles (1,100°C ΔT) |
| High-Alumina | 45–75% | 1,600°C | 50–100 MPa | 12–18% | >25 cycles |
| Insulating | 30–40% | 1,200°C | 5–15 MPa | 60–75% | N/A (low mechanical stress) |
Kerui’s KR-HA70 High Alumina Bricks (Al₂O₃ ≥70%) achieve 1,350°C stability with <15% porosity.
2.2 Comparative Advantages
- Thermal Conductivity: Kerui’s insulating bricks (0.3 W/m·K) outperform competitors by 25%.
