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.
Calcined alumina is a product obtained by calcining aluminum hydroxide at high temperature to partially or almost completely convert it into aAl2O2.

High alumina refractory mortars used in kilns in metallurgy, building materials, machinery, chemical industry, electric power and other industries, used for masonry clay bricks, high alumina bricks, corundum bricks, with full ash joints, good air tightness of masonry, high bonding strength, high temperature performance Excellent, suitable for construction time and so on.
The alkali-resistant brick for cement kiln has the characteristics of strong alkali erosion resistance, good thermal shock resistance and high cost performance.
Anti stripping high alumina bricks are referred to as anti-stripping bricks or anti-stripping refractory bricks. Anti-stripping high-alumina bricks are widely used in my country's new dry process kiln, Libore kiln and wet process kiln, including kiln door cover, rising flue, cooling zone, decomposition zone, safety belt, transition zone, coolant rear Walls and side walls and beams with curved ceilings.
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.
