Brown fused alumina is primarily made from bauxite and coke (anthracite) through high-temperature smelting in an electric arc furnace. The abrasives made from it are suitable for grinding metals with high tensile strength, such as various carbon steels, malleable cast iron, and hard brass, and can also be used to produce refractory materials. Brown fused alumina boasts high purity, good crystallinity, strong fluidity, low linear expansion coefficient, and corrosion resistance. After being verified by dozens of refractory material manufacturers, the product exhibits non-explosive, non-pulverized, and non-cracking properties during application. Particularly, its superior cost-performance ratio compared to traditional brown fused alumina makes it the ideal aggregate and filler for brown fused alumina-based refractory materials.
Brown fused alumina application range
Brown fused aluminum oxide, known as the "teeth of industry," is primarily used in refractory materials, grinding wheels, and sandblasting.
1. Used for manufacturing refractory materials, casting materials, refractory bricks, etc.
2. Sandblasting - With moderate abrasive hardness, high bulk density, no free silicon dioxide, high specific gravity, and good toughness, it is an ideal "environmentally friendly" sandblasting material widely used in aluminum profiles, copper profiles, glass, fine molds for washing denim clothing, and other fields.
3. Free Grinding - Grinding-grade abrasive, used for free grinding in fields such as cathode ray tubes, optical glass, single crystal silicon, lenses, glass for watches, crystal glass, jade articles, etc., is a widely used grinding material in China.
4. Resin Abrasive Tools - The abrasive has suitable color, good hardness, tenacity, appropriate particle cross-sectional type, and blade retention, which is ideal for use in resin abrasive tools.
5. Abrasive Belts - The abrasive material used is the production raw material for sandpaper, cheesecloth manufacturers, etc.
6. Functional Filler - Primarily used in automotive brake parts, special tires, and special building products, it can also be used as a wear-resistant material for constructing highways, airport runways, docks, parking lots, industrial flooring, and sports fields.
7. Filter Media - A novel application field for abrasives, using granular abrasives as the bottom layer medium for the filter bed, to purify drinking water or wastewater. It is a new type of water filtration material both domestically and internationally, particularly suitable for non-ferrous metal ore beneficiation: oil drilling mud weighting agent:
8. Water Jet Cutting – Utilizes abrasive as the cutting medium and relies on high-pressure water jets for basic cutting. Applied to the cutting of oil pipelines, steel components, and more, it is a new, environmentally friendly, and safe cutting method.
