Introduction
Black Fused Alumina is also known as low aluminum corundum. It is also a new

type product of polishing material, and it is a dark gray crystal body made Al2O3 and

ferropicotite as main ore in the electric arc furnace by smelting the bauxite. It has

characteristics of moderate hardness, high toughness, high temperature resistance, and

stable thermal stability.


Applications
1. Blasting corundum - the abrasive blasting with moderate hardness, high bulk density, no free silica, heavy, good toughness, corundum is the ideal "green" blasting material, widely used in aluminum , the copper profile glass, washed jeans precision mold areas;

2. Free grinding - grinding grade abrasives, used in cathode-ray tube, optical glass, silicon, lenses, clocks, glass, crystal glass, jade and other areas of free grinding, abrasive materials is widely used in domestic;

3. Resin Abrasives - Abrasive have the right color, hardness, toughness, suitable particle cross-section type and edge retention, used in resin abrasive, the results are satisfactory;

4.Coated abrasives - abrasive sandpaper, gauze and other manufacturers of raw materials;

5.Corundum functional filler - mainly used in automotive brake parts, special tires, specialty building products , can be used as wear-resistant materials of construction of motorways, runways, docks, parking lots, industrial floor, stadium, etc ;

6. Filter medium - new abrasive applications, the bottom of the filter bed is particulate abrasive for medium to purify drinking water or wastewater, is a new type of water filter material, particularly suitable for non-ferrous metal processing oil drilling mud weighting agent ;

7. Abrasive water-jet cutting - abrasive as cutting media rely on high-pressure water jet cutting, cutting oil (gas) pipelines, steel components, a new, environmentally safe cutting mode.

Smelting of black fused alumina powder

The smelting method of black fused alumina is basically same with smelting of brown corundum. The production method of black fused alumina is choosing high-quality bauxite, iron oxide and other raw materials, add other trace elements, carefully smelting in dumping-type electric arc furnace , to ensure that the massive black fused alumina block are top grade, less impurities, ,stable quality. This laid solid foundation for producing period of black fused alumina sand , grain size black fused alumina sand and black fused alumina powder that are of moderate hardness, good toughness, good using performance and stability quality.
Prices of black fused alumina powder
In the abrasive products, brown fused alumina, white fused alumina, black fused alumina are same in using bauxite as main raw material, add iron scrap in high-temperature electric arc furnace smelting, and why the price of black fused alumina is lower than price of brown fused alumina and black fused alumina , The price of aluminum in the market than the price of iron per ton to be much higher, brown fused alumina sand content of more than 95%, while the black fused alumina a sand content of aluminum oxide To 85%, we can see the same level of fused alumina aluminum content is much higher than black fused alumina, and fused alumina products in the most valuable component is alumina, therefore, the price of black fused alumina is much lower than white fused alumina and brown corundum.

Black fused alumina, also known as low-aluminum corundum, is a gray-black crystal with α-Al2O3 and iron spinel as the main ore phase, which is obtained by melting aluminum bauxite in an electric arc furnace. It is characterized by low Al2O3 content. There is a certain amount of Fe2O3 (about 10%), so it has the characteristics of moderate hardness, high toughness, high temperature resistance and stable thermal performance. It is mostly used for free grinding, such as grinding and rough grinding before electroplating of products. It is mainly used for polishing and sand blasting of stainless steel, metal products, optical glass, bamboo and wood products, and is also a novel abrasive for manufacturing resin grinding wheels, cutting sheets and abrasive cloths.

Black corundum and low aluminum corundum, 3 oxidation 2 aluminium (AI2O3) content is 70% ~ 70%, containing more silicon oxide and titanium oxide impurities, such as a corundum in black. Melting point : 2050. In electric arc furnace, bauxite made by melting a is given priority to with alpha Al2O3 and spinel mineral phase - colored crystals, its characteristic is Al2O3 content is lower, and has a certain amount of Fe2O3 (10%), thus has moderate hard ground, high toughness, high temperature resistant, the characteristics of the thermal state performance is steady. More for free grinding, such as products before electroplating grinding coarse grinding, it is mainly used for stainless steel, metal products, optical glass, bamboo and wood products polishing and sanding, making resin grinding wheel, cutting slices, gauze of new abrasive. Black corundum abrasive basic particle concentration, strong cutting force, tenacity is big, and flexibility, good abrasion resistance, high working efficiency. Grinding polishing, sandblasting of stainless steel products is the most ideal products.

Brown fused alumina introduction
Brown fused alumina, local name, also known as carborundum, is made of alumina, carbon materials, scrap iron three kinds of raw materials in electric furnace melting reduction and made of brown alundum, reason for this name.Brown fused alumina is mainly chemical composition is AL2O3, and its content from 94.5% to 94.5%, the other contains a small amount of Fe, Si, Ti, etc.
Brown fused alumina is bauxite, coke, anthracite as main raw materials, in the Canon of high temperature smelting electric arc furnace and become, use it made of abrasive, suitable for grinding the high tensile metals, such as all kinds of steel, malleable cast iron, hard bronze, etc., also can make advanced refractories.Brown fused alumina with high purity, good crystallization, strong liquidity, low linear expansion coefficient, the characteristics of corrosion resistance.The dozens of refractory production enterprises have proved that the product in the application process has not initiation, not pulverization, not cracking characteristics.Especially its far higher than the traditional brown corundum price, more make it become the best in the brown just the quality of the jade of refractory aggregate and filling material.
