// SPEC · Monolithic Refractories
Premium Dense Castable Al2O3 80%
Premium dense castable Al2O3 80% for EAF working linings and petrochemical furnaces. Exceptional high-temperature strength, slag resistance, and low porosity meet the demands of electric steelmaking and refinery thermal equipment.
// Key Features
- High refractoriness to 1700°C for electric arc and petrochemical service
- High bulk density and low apparent porosity limiting slag infiltration
- Excellent hot modulus of rupture under sustained thermal load
- Strong resistance to CO atmosphere and oxidizing conditions
