Corundum Furnace for Smelting White Fused Alumina, Brown Fused Alumina, Dense Alumina & Zirconia Alumina

1. High-Temperature Capability

   • Operates at 2000°C+ to melt ultra-hard abrasives and refractories.

   • Ideal for producing white fused alumina (WFA), brown fused alumina (BFA), dense fused alumina (DFA), and zirconia corundum (AZS).

2. Advanced Applications

   • Abrasives: Manufacture grinding wheels, sandpapers, and precision polishing compounds.

   • Refractories: Produce high-purity linings for kilns, furnaces, and ladles.

   • Specialty Ceramics: Synthesize zirconia-toughened alumina (ZTA) for extreme environments.

3. Furnace Technology

   • Arc/Submerged Arc Design: Ensures energy-efficient melting with precise temperature control.

   • Cooling System: Prevents thermal stress in crucibles/lining for extended lifespan.

4. Material Properties Achieved

   • White Fused Alumina: ≥99% Al2O3, high hardness (Mohs 9).

   • Zirconia Corundum (AZS): 10-40% ZrO2, superior corrosion/thermal shock resistance.
