Description
Silicon-Mullite Brick
Material System & Positioning
Silicon-mullite bricks combine mullite and silicon carbide (SiC ≥20%): Al₂O₃ ≥55%, bulk density ≥2.65 g/cm³ and CCS ≥60 MPa. Wear- and coating-resistant with low thermal conductivity and good erosion resistance, they are ideal for cement kiln coolers, kiln mouths and transition zones. It is Henan Songrui's professional grade for the cement industry.
Key Performance
- Mullite-SiC composite: wear and coating resistance against material abrasion and gas flow.
- Low thermal conductivity: cuts heat loss.
- Clinker-coating resistance: promotes stable coating.
- Reliable strength: CCS ≥60 MPa.
Applications
- Cement: kiln mouth protection, transition zones, cooler side walls/arches, tertiary air ducts.
- Lime: hot zones.
- Non-ferrous: roaster linings.
Selection Advice
Use for kiln mouths, transition zones and coolers where abrasion and cycling coexist; combine with spalling-resistant high-alumina and magnesia-alumina spinel for full-kiln selection. Lay with matching mortar to promote coating.
Installation & Maintenance
Lay with matching mortar, tight joints; heat up per the cement kiln schedule.
