Dense Castable

Corundum Dense Castable Al2O3 95%

Corundum dense castable Al2O3 95% for gasifiers, coal injection lances, and highest-demand industrial applications. Extreme refractoriness, maximum density, and superior resistance to molten slag and reducing atmospheres.

λ = 3.0 W/(m·K) at 1000°C

Dense Castable Al2O3 60% Standard Grade

Dense Castable Al2O3 60% standard grade refractory for industrial furnace working linings. High refractoriness, good mechanical strength, and reliable slag resistance for steel mills, cement plants, and power boilers.

λ = 1.3 W/(m·K) at 1000°C

Dense Castable Al2O3 70%

High alumina dense castable with 70% Al2O3. Excellent strength, density, and erosion resistance for industrial furnace linings.

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.

λ = 1.8 W/(m·K) at 1000°C

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.

λ = 2.0 W/(m·K) at 1000°C

Ultra-Low Cement Dense Castable Al2O3 85% (CaO<0.5%)

Ultra-low cement dense castable Al2O3 85% with CaO<0.5% for near-zero porosity service in steel degassers, gasifiers, and petrochemical crackers. Maximum hot strength and chemical purity for the most demanding thermal environments.

λ = 2.3 W/(m·K) at 1000°C
