Product Description
Red Clay Refractory Brick Material
Product Overview
Specialized refractory bricks designed for clay brick production lines, featuring low thermal conductivity and exceptional spalling resistance. Manufactured using alumina fine powder, andalusite, and bound clay through hydraulic pressure forming and firing processes.
Key Features
- Excellent resistance to alkali erosion
- Superior thermal shock resistance (≥15 cycles at 1100°C)
- Low thermal conductivity (≤1.5 W/m.K at 700°C)
- High cold crushing strength (≥45 MPa)
- Reduced kiln shell load and mechanical stress
- Customizable dimensions and specifications
