brown alumina oxide

Brown alumina oxide lso known as emery, is a brown artificial corundum made from the melting and reduction of alumina, carbon materials and iron filings in an arc furnace. The main chemical composition of brown corundum is AL2O3, whose content is 95.00% - 97.00%, with a small amount of Fe, Si, Ti, etc. Brown corundum is the most basic abrasive, because its grinding performance is good, the scope is wide, the price is cheap, is widely used.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 corundum has high purity, good crystallization, high fluidity, low coefficient of linear expansion and corrosion resistance. Through the practice of dozens of refractory production enterprises, the product has the characteristics of non-detonation, non-pulverization and non-cracking in the application process. In particular, it is far higher than the traditional brown corundum, which makes it the best aggregate and filling material for the refractory material of brown jade.

The use range of brown corundum oxide

1. The functional filler - is mainly used for automobile brake parts, special tires, special construction products such as led can be used as building highway pavement. The runway. Dock. The parking lot. Industrial floor. Sports venues such as wear-resistant materials;

2. Filter medium, is a new kind of application field, abrasive using granular grinding for the bottom of the medium filter bed, purify drinking water or wastewater, is a new type of water filtration materials at home and abroad, especially suitable for non-ferrous metal processing, oil drilling mud weighting agent:

3. Hydraulic cutting - an abrasive cutting medium, rely on high pressure water jet cutting, basic application in the oil (gas) pipe, steel components, such as cutting, is a new type, environmental protection, safe way of cutting.
