F24 Barmac Crushed Round Grain Brown Corundum , Grinding Wheel Aluminium Oxide

F24 Barmac Crushed Round Grain Brown Corundum For Vitrified Bonded Grinding Wheels
 
Brown Fused Alumina 95% Introduction

Brown corundum is made of bauxite and coke (anthracite) by high temperature smelting in electric arc furnace. The abrasives made of brown corundum are suitable for grinding metals with high tensile strength, such as all kinds of general steel, malleable cast iron, hard bronze, etc., and can also be used to manufacture high-grade refractory materials. Brown corundum has the characteristics of high purity, good crystallization, strong fluidity, low coefficient of linear expansion and corrosion resistance. The practice of dozens of fire-resistant enterprises has proved that the product has the characteristics of no initiation, no pulverization and no cracking in the application process. Especially, its cost performance is much higher than that of traditional brown corundum, which makes it the best aggregate and filler of brown corundum refractory.

Brown Fused Alumina Characteristics
High hardness, high crystallinity, good linear flow performance, weak adherence, no explosion while using, no cracking, no pulverizing, abrasive product with dark blue color after burning, no net cracks, no rust.

Brown Fused Alumina Properties

 
Brown Fused Alumina Applications

Brown corundum is called industrial tooth: it is mainly used in refractories, grinding wheels and sandblasting.

1. It is used for manufacturing high-grade refractory, castable, refractory brick, etc.

2. Sand blasting -- the abrasive has moderate hardness, high bulk density, no free silica, large ratio and good toughness. It is an ideal "environmental protection" sandblasting material, which is widely used in aluminum profiles, copper profiles, glass, water washed jeans precision mold and other fields;

3. Free grinding - abrasive grade, which is widely used in the free grinding of kinescope, optical glass, monocrystalline silicon, lens, clock glass, crystal glass, jade and other fields, is a high-grade grinding material widely used in China;

4. Resin abrasives -- Abrasives have suitable color, good hardness, toughness, appropriate particle section type and edge retention, which can be applied to resin abrasives with ideal effect;

5. Coated abrasive is the raw material of sandpaper, gauze and other manufacturers;

6. Functional filler - mainly used for automobile brake parts, special tires, special building products, etc., and can be used as wear-resistant materials for highway pavement, runway, wharf, parking lot, industrial floor, sports ground, etc;

7. Filter media -- it is a new application field of abrasives. Granular abrasives are used as the bottom media of the filter bed to purify drinking water or wastewater. It is a new type of water filtering material at home and abroad, especially suitable for non-ferrous metal mineral processing

8. Hydraulic cutting is a new, environmentally friendly and safe cutting method, which uses abrasive as cutting medium and relies on high-pressure hydraulic jet for basic cutting, which is applied to the cutting of oil (natural gas) pipeline, steel and other parts.
