| High Light | Bauxite refractory castables for foundry ，Mullite corundum castables for furnace ，Dry ramming mass for alumina industry | ||
Our specialized Refractory Castables are formulated using an Ultra-Low Cement (ULC) matrix, significantly reducing the CaO content to enhance high-temperature structural integrity. By integrating sintered bauxite, mullite, and corundum aggregates, we have engineered a high-density solution that minimizes the formation and growth of corundum "mushrooms" in alumina environments. These castables offer superior fluidity for seamless installation in complex furnace geometries, ensuring a monolithic lining with exceptional density.
To move beyond generic descriptions, our Refractory Castables are subjected to rigorous laboratory stress tests. The following data benchmarks confirm the material's resistance to thermal shock and molten metal erosion:
Test Condition: Heating to 1100℃ followed by immediate water quenching.
Result: >30 Cycles without spalling or macro-cracking.
Technical Proof: This extreme durability validates a 20% increase in furnace service life, even in high-cycling reverberatory furnace operations.
Test Condition: Immersion in molten aluminum alloy 7075 at 850℃ for 72 hours.
Result: Zero metal penetration and "Superior Non-Wetting" characteristics.
Benefit: Minimizes dross buildup and slag chemical attack, maintaining a clean furnace hearth.
Test Standard: ASTM C583 at 1400℃.
Data Backing: HLL-85 exhibits a residual strength significantly higher than standard bauxite castables, ensuring structural stability under mechanical load at peak refractoriness.

| Al2O3 Content | 84% | 79% | 68% | 59% |
| Bulk Density | 2.8 g/cm3 | 2.8g/cm3 | 2.6g/cm3 | 2.5g/cm3 |
| Refractoriness | 1700℃ | 1100℃ | 1100℃ | 1650℃ |
| Grain Size | 0-10 mm | 0-6 mm | 0-6 mm | 0-6 mm |
| Thermal Change | 10% Less Energy Loss | High Corrosion Resistance | High Thermal Shock Resist | Excellent Hot Strength |
These Refractory Castables are specifically optimized for the high-wear zones of the Alumina and Foundry industries:
Alumina Reverberatory Furnaces: Use HLL-85 in the belly-band and hearth zones to resist molten aluminum penetration and chemical erosion.
Foundry Ladles & Troughs: HLC-70 and HLC-80 provide the necessary thermal shock resistance for intermittent pouring operations and metal transport.
Dry Ramming Mass Alternative: For alumina industry induction furnaces, our dry ramming mass options provide 20% longer furnace life compared to traditional silica linings.
