Product Description

   Brown Fused Alumina ( Corundum ) Powder For High Grade Refractories

Product Description

Brown corundum is Using bauxite and charcoal (anthracite) as raw material and fused under high temperature in an electric arc furnace. The main chemical components are Al2O3 and TiO2. It also contains small amounts of SiO2 and Fe2O3, etc. The microhardness is 1800-2200kg/mm2. The toughness is higher than Silicon Carbide. The abrasive tools made by brown fused alumina are suitable for grinding carbon steel, normal alloy steel, malleable cast iron, hard bronze, etc. Brown fused can also make fine quality refractory, etc. The refractoriness of high-alumina clinker is up to 1850ºC. It has strong chemical stability and good physical properties.

Product Application

Refractory Materials

Brown fused alumina is mainly used in refractory materials, iron hook castables, water-free mud,
corundum bricks, prefabricated parts, breathable bricks, ladle bricks, magnesia-alumina-carbon bricks, etc.

Silicon-aluminum Series
It is generally used in refractory materials for aggregates and fine powders, mainly for the silicon-aluminum series.
The volume is stable when making products. However, since impurities have not been completely removed during smelting
It also contains secondary crystal phases such as calcium hexaaluminate, anorthite, spinel, and rutile, as well as glass phases,erroalloys,
and solid solutions. Therefore, the impurities of brown fused alumina determine the life of brown fused alumina products during use.

Foundry Industry
In the foundry industry, It is suitable for making large-scale steel castings, especially the mold (core) surface sand, paste, and paint of alloy steel castings.The investment casting shell made of brown fused alumina has good dimensional stability, thermal stability, and high-temperature chemical stability,and is a good refractory material for investment casting. Due to its high price, it is only used as a molding material for castings such as heat-resistant high-alloy steel, stainless steel, and magnesium alloy.

Blast cleaning :
Use for blast cleaning of steel board. H type steel, steel pipe and all kinds of steel material, casting, die-casting, gorging,
glass surface for industries of steel structure, construction, bridge, shipbuilding, pipes, container, locomotive, engineering machinery, automobile, casting, forging, glass, comodity.
 
Shot peening:
Used for shot peening of spring, shaft, gear, connecting bar, blade, chain, crank,
wheel spares for industries of automobile, locomotive, ship, plain, machine.
