Brown Fused Alumina Manufacturing Process & Industrial Application

As the best refractory aggregate and filling material, brown fused alumina is made by fusing and purifying in a pouring electric arc furnace at a temperature of over 2200° C with high-quality bauxite, carbon material, and iron filings as the main materials. Finally a variety of particle sizes products are made by purifying, crystallization, sorting, crushing, magnetic separation and screening, washing and acid washing, etc. The raw material of brown fused alumina is aluminum oxide powder. The main chemical component of brown fused alumina is Al₂O₃, whose content is 98.65% to 99.37%, besides which it contains slight Fe, Si, and Ti. White fused alumina is a good raw material for ceramics, resin-bonded abrasive products, grinding, polishing, sandblasting, precision casting, and the manufacturing of advanced refractory materials.

The industrial application of brown fused alumina is wide:

1. Sand Blasting

As abrasives, brown fused alumina is moderate in hardness, high in bulk density and tenacity, and does not contain any dissociative, so it is the most ideal material for environmental sand blasting. It is widely used in aluminum profile and copper profile glass, water-washed jeans, precision mould, etc.

2. Free Grinding

Grinding abrasives are used in kinescope, optical glass, mono crystalline silicon, lens, crystal glass, jadeware, etc. Brown fused alumina is universally used as superior grinding material.

3. Resin-bonded Abrasive Products

The proper color, hardness, and toughness have guaranteed the ideal effect of brown fused alumina to be applied in resin-bonded abrasive products.

4. Coated Abrasive Products

Brown fused alumina is the raw material of abrasive paper and abrasive cloth.

5. Brown Fused Alumina Functional Stuffing

6. Brown Fused Alumina Functional Stuffing is mainly used in auto brake components, special tires, special building products, construction of expressways, runways, wharfs, parking lots, sports ground, etc.

7. Water Jet Cutting

Brown fused alumina abrasive is used as a cutting medium to cut based on high pressure water jet. It is a new, environmental friendly, and safe cutting method used in oil (or natural gas) tubes, steel materials cutting.
