Brown Fused Alumina for Furnace Linings
Durable refractory aggregates for lining high-temperature industrial furnaces, kilns, and incinerators.
Why Use BFA in Furnace Linings?
Brown fused alumina (BFA) is widely used as a refractory aggregate in monolithic linings and shaped bricks for industrial furnaces. Its high alumina content, hardness, and thermal shock resistance make it ideal for extending furnace service life under extreme thermal and chemical conditions.
- Resistant to slag erosion and thermal cycling
- Maintains structural integrity above 1800°C
- Excellent load-bearing and insulating properties
Typical Applications in Furnaces
- Electric arc furnace (EAF) walls and hearths
- Glass furnace crowns and regenerators
- Rotary kiln linings in cement and lime production
- Incinerators and thermal oxidizer linings
BFA can be used in dense castables, ramming masses, or bonded bricks depending on the system.
Recommended Grain Sizes
- Refractory castables: 1–3 mm, 3–5 mm, 5–8 mm aggregates
- Matrix or bonding phases: F60–F220 powders
- Precast shapes: Blended grain formulations
All materials are tested for high thermal conductivity and mechanical strength under load.
