brown corundum

Brown corundum, also 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

1 sandblasting abrasive hardness is moderate, high packing density, no free silica, than major, good toughness and is the ideal "environmental protection" type sand blasting materials, widely used in aluminum, copper profile glass, washing jeans precision molds, and other fields;

2.resin grinding tools - abrasive with suitable color, hardness, toughness, suitable particle section type and cutting edge retention, applied to resin grinding tools, ideal effect;

3. 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;
