Description

Brown fused alumina is on sale with very competitive price, quality guarantee, enough stock quantity.

Brown aluminum oxide is made of calcined bauxite and coke, iron as the main raw material. It is smelted by high temperature in an electric arc furnace. The abrasive tool made of it is suitable for grinding high tensile resistance metals, such as various general steels, malleable iron, hard bronze, etc., can also be made of advanced refractory materials.

Brown fused alumina has the characteristics of high purity, good crystallization, strong fluidity, low coefficient of linear expansion and corrosion resistance. It has been verified by dozens of refractory production enterprises that the product has the characteristics of no explosion, no powdering and no cracking in the application process. In particular, it is much higher than the cost performance of traditional brown fused alumina, making it the best aggregate and filler for brown corundum refractories.

Product Application:

Brown fused alumina also named corundum or electro corundum, is called industrial teeth: mainly used in refractory materials, grinding wheels, sand blasting.

1. Used in the manufacture of advanced refractory materials, castables, refractory bricks, etc.

2. Sand blasting - moderate hardness of abrasive, high bulk density, no free silica, large specific gravity, good toughness, is an ideal "environmental" type sand blasting material, widely used in aluminum profiles, copper profile glass, washed denim Precision molds and other fields.

3. Free grinding - grinding grade abrasive, applied to the free-grinding of fields such as picture tube, optical glass, monocrystalline silicon, lens, watch glass, crystal glass, jade, etc., is a high-grade abrasive material commonly used in China.

4. Bonded abrasives - abrasives with suitable color, hardness, toughness, suitable particle cross-section type and edge retention, applied to resin abrasives, the effect is ideal.

5. Coated abrasives - as main raw material of abrasive paper and abrasive cloth.

6. Functional fillers - mainly used in automotive brakes, special tires, special construction products, etc. can be used as a highway pavement. Aircraft runway. Terminal. Parking lot. Industrial floor. Sports ground and other wear-resistant materials.

7. Filter medium - It is a new application field of abrasive. It uses granular abrasive as the bottom medium of filter bed to purify drinking water or waste water. It is a new type of water filtration material at home and abroad, especially suitable for non-ferrous metal beneficiation: oil drilling mud weighting agent.

8. Hydraulic cutting - It is a cutting medium with abrasive material. It relies on high-pressure hydraulic jet for basic cutting. It is applied to the cutting of petroleum (natural gas) pipelines, steel and other components. It is a new, environmentally friendly and safe cutting method.
