Corundum Furnace for Smelting White Fused Alumina, Brown Fused Alumina, Dense Alumina & Zirconia Alumina
-
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).
-
-
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.
-
-
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.
-
-
Material Properties Achieved
-
White Fused Alumina: ≥99% Al2O3, high hardness (Mohs 9).
-
Zirconia Corundum (AZS): 10-40% ZrO2, superior corrosion/thermal shock resistance.
