Description
Chrome-Corundum Brick
Material System & Positioning
Chrome-corundum bricks introduce chromia (Cr₂O₃ 3-8%) into a corundum matrix: Al₂O₃ ≥90%, refractoriness ≥1950℃ and CCS ≥70 MPa. Chromia markedly improves glass-melt erosion resistance; low glassy phase and high density make them the dedicated material for glass tank walls, doghouses and tuckstones. Supplied by Henan Songrui for demanding glass furnace erosion zones.
Key Performance
- Glass-melt resistance: chromia-enhanced corundum matrix.
- Dense and pure: minimal glassy phase.
- Balanced shock/erosion resistance: suits temperature swings and liquid flow.
- Dedicated zones: tank walls, doghouses, tuckstones.
Applications
- Glass: tank walls, bottoms, doghouses, tuckstones, throats.
- Associated: transition zones with fused-cast AZS.
Selection Advice
Use chrome-corundum or fused-cast AZS for direct glass-contact zones; verify environmental compliance. Lay in tight joints to prevent glass leakage.
Installation & Maintenance
Lay in tight joints with matching mortar; verify shapes and numbers before laying.

Typical Applications
Chrome-corundum brick adds Cr₂O₃ for superior erosion resistance:
- Non-ferrous: copper flash smelter shaft and settler, converters, nickel furnace slag lines.
- Glass: tank wall attack zones, regenerators (alkali vapor).
- Waste-to-energy: high-temperature corrosive walls.
- Petrochemical: gasifier slag pools.
- Advantage: service up to 1800℃, Cr₂O₃ enhances basic-slag and metal resistance.
FAQs
