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 refractory ramming material is prepared from a high proportion of granular and powdery materials and a very low proportion of binders and other components, even all of which are composed of granules and powders, and are subject to strong ramming. Bulk materials for construction.
The high-alumina refractory bricks sold by Yuying refractory manufacturers are commonly used refractory bricks with high thermal stability and refractoriness above 1770°C. It has good slag resistance and is used for the lining of steelmaking electric furnaces, glass melting furnaces, cement rotary furnaces, etc.
GONGYI YUYING REFRACTORY CO.,LTD is located in GONGYI ZHENGZHOU CITY HENAN province,which is one of the main refractory production bases in China. Main products include different kinds of refractory brick and refractory material :Such as Fire Clay Brick, High Alumina Brick, Light Weight Insulating Brick,expanded clay,ceramic fiber blanket,rock wool products etc.They are widely used in Iron and steel, Nonferrous metals, BuildingMaterials(Cement,Glass,Ceramic), Petrochemical, Energy & Incineration etc industries.
Fireclay bricksis suitable for supporting hot blast stoves of large, medium and small blast furnaces
Anhydrous taphole mud/taphole clay refers to taphole mud made of tar, resin, etc. as binders and corundum, bauxite, clay, silicon carbide, coke powder, etc. as raw materials. Anhydrous carbon taphole mud is made by a mud mill. When rolling, oil is added first, then block materials (clay and asphalt), and then powder materials (coke powder and clinker powder) are added after crushing. After pressing and mixing, the mud can be produced when it meets the standards.
Anchor bricks are anchor bricks for industrial kilns. The electric furnace roof is a furnace roof structure supported by metal hanging bricks and refractory bricks. Therefore, the leakage of reactive gas and hot gas in the furnace will damage the metal hanging parts, thereby causing furnace damage. roof collapse accident. Anchor bricks are also called hanging bricks and anchors.
