F4-F320 BFA Good Quality Brown fused alumina for sale Brown Corundum refractory
Brown fused alumina, also known as emery, is a brown synthetic corundum made from three raw materials, bauxite, carbon and iron scrap, which are melted and reduced in an electric arc furnace, hence its name. The main chemical composition of brown fused alumina is AL2O3, whose content ranges from 95.00% to 97.00%, and contains a small amount of Fe, Si, Ti, etc. Brown fused alumina is the most basic abrasive, which is widely used because of its good grinding performance, wide application range and low price.
Brown fused alumina is made of bauxite, coke (anthracite) as the main raw materials, and is smelted at high temperature in arc furnace. It is a grinding tool made of it, suitable for grinding metals with high tensile strength, such as all kinds of common steel, malleable iron, hard bronze, etc., and it can also be used for manufacturing high-grade refractory materials. Brown fused alumina has the characteristics of high purity, good crystallization, strong fluidity, low linear expansion coefficient and corrosion resistance. It has been verified by the practice of dozens of refractory production enterprises that the product has the characteristics of no detonation, no pulverization and no cracking in the application process. In particular, it is much higher than the traditional brown corundum cost performance, which makes it become the best aggregate and filler of the brown corundum .
refractories.
There are generally three methods for brown fused alumina smelting:
1. Discharge: continuous production, high degree of automation, but large investment, complex structure, suitable for high-power smelting.
2. Dumping method: continuous production, high degree of mechanization, small investment, good production efficiency, the current use of a common method.
3. Fixed method (frit method) : Discontinuous production, low degree of mechanization, but small investment, simple equipment, convenient technology, is the main method of corundum smelting in small abrasive plants.
The appliciation of F4-F320 BFA Good Quality Brown fused alumina for sale Brown Corundum refractory
Brown fused alumina is called the tooth of industry: it is mainly used in refractory materials, grinding wheels, sand blasting.
1. Used for manufacturing high-grade refractory, castable, firebrick, etc.
2, sandblasting -- abrasive hardness moderate, high accumulation density, no free silica, significant ratio, good toughness, is the ideal "environmental protection" sandblasting material, widely used in aluminum, copper profile glass, washed jeans precision mold and other fields;
3, free grinding -- grinding grade abrasive, applied in the picture tube, optical glass, monocrystalline silicon, lens, watch glass, crystal glass, jade and other fields of free grinding, is widely used in the domestic advanced grinding materials;
4, resin abrasive - abrasive color, good hardness, toughness, suitable particle section type and edge retention, applied to resin abrasive, the effect is ideal;
5. Coated abrasives -- abrasive is the raw material of sandpaper, gauze and other manufacturers;
6. Functional filler -- mainly used for automobile brake parts, special tires, special construction products, etc., which can be used as wear-resistant materials for highway pavement, airstrip, wharf, parking lot, industrial floor, sports field, etc.;
7. Filter medium -- it is a new application field of abrasive. It USES granular abrasive as the bottom medium of the filter bed to purify drinking water or waste water.
8, hydraulic cutting -- abrasive as the cutting medium, rely on high pressure hydraulic jet for basic cutting, used in oil (natural gas) pipelines, steel and other parts of the cutting, is a new, environmental protection, safe cutting way.
