Low Cement Dense Castable Al2O3 75% (CaO<1%)
Low cement dense castable Al2O3 75% with CaO<1% for high-strength steel and glass furnace linings. Reduced calcium oxide yields higher density, greater mechanical strength, and improved slag resistance versus conventional castables.
// Key Features
- Low cement (CaO<1%) delivering higher density and mechanical strength
- Reduced low-melting calcium aluminate phases improving hot strength
- Low apparent porosity for superior resistance to slag and steel penetration
- Excellent volume stability across repeated thermal cycling
