Brown Fused Alumia powders are fused wIth premium raw materials and 3500 KVA furnace. It is perfect material specifically manufactured to be used for general abrasive applications in bonded abrasive tools, polishing and sandblasting grit. It has lower hardness and abrasive capacity than diamond, boron carbide, and silicon carbide, it is widely used for grinding ferrous materials, finishing tough and hard materials. It is also be used as high-class refractory materials. Brown Fused Alumia is offered in macro and micro powder form, in both F and P grades.
Brown fused alumina for refractory
brown corundum is called industrial teeth: mainly used in refractory raw materials, grinding wheels, sand blasting.
Sandblasted brown corundum – sandblasted abrasive with moderate hardness, high bulk density, no free silica, large specific gravity and good toughness. It is an ideal “environmentally friendly” sandblasting material widely used in aluminum profiles and copper profiles. Washed denim clothing precision molds and other fields;
Free grinding - grinding grade abrasives, used in the fields of picture tube, optical glass, monocrystalline silicon, lens, glass for clocks, crystal glass, jade and other fields, is a high-grade abrasive material commonly used in China;
Resin Abrasives—Abrasives have suitable color, good hardness, toughness, suitable particle cross-section type and edge retention. They are used in resin abrasives with good results.
Coated abrasives—abrasives are raw materials for the production of sandpaper, gauze, etc.
Brown corundum functional filler - mainly used for automobile brake parts, special tires, special construction products, etc. It can be used as a wear-resistant material for highway pavement, airstrip, dock, parking lot, industrial floor, sports ground, etc.
Filter media – it is a new application field of abrasives. It uses granular abrasive as the bottom media 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 and oil drilling mud weighting agent.

White corundum is made from industrial alumina powder, which is smelted in an arc at a high temperature above 2000 ℃ and then cooled. After crushing and shaping, magnetic separation to remove iron, it is divided into various particle sizes.
Brown corundum is made of natural bauxite as raw material, carbon (mainly coke) is used as reducing agent, and iron filings are added as sedimentation agent (clarifier) to form ferrosilicon deposited on the bottom of electric furnace.
The alumina ball is also called the high aluminum accumulation of heat ball.High alumina refractory ball is based on bauxite as the mainly raw refractory material.Adding powder and additives and anchoring agent.After proportioning, molding and high sintering to make it.The production engineering of high alumina refractory ball is similar to that of high alumina refractory brick.It should be based on the properties of raw materials,high alumina refractory ball requires production conditions and other factors to determine.
Ceramic wear resistant castable is a special material and is a new type of material developed recently. It not only meets the needs of national defense cutting-edge products and high-tech development, but also meets the requirements of the rapid development of the national economy. Therefore, it is easier for users to accept than other materials, so it develops rapidly.
The alkali-resistant brick for cement kiln has the characteristics of strong alkali erosion resistance, good thermal shock resistance and high cost performance.
Silica brick: an acidic refractory mainly composed of tridymite, cristobalite and a small amount of residual quartz and glass phases. Its silica content is more than 94%, it has anti-acid slag erosion performance, high high temperature strength, high load softening temperature, long-term use in high temperature flower wells without deformation, but low thermal shock stability (heat exchange in water is 1-4 Second-rate).
The heavy part of the raw materials for the chrome zirconium corundum composite brick is sintered tabular corundum, high-purity chromium oxide, high-purity zircon, and Guangxi white cement.As the main raw material, the light part of the raw material is made of 47 mullite, kyanite, floating beads and coke gemstones as the main raw materials. During molding, a separator is set in the middle of the mold, and heavy materials and light materials are added at both ends. After high pressure molding , finished products made of high temperature sintering.
The chemical composition of bauxite is mainly Al2O3, SiO2, Fe2O3, TO2, accounting for about 95% of the total composition, and the secondary components are CaO, MgO, K2O, Na20, S, MnO2 organic matter and trace components Ga, Ge, etc.
