Direct Manufacturer of White Fused Alumina As The Material of Corundum Brick

We specialized in manufacturing grit/micro powder of corundum powder-white fused alumina. Good quality and competitive price make our products well accepted by customers at home and abroad. You are welcome to contact us for further information .

1. Description:

White Aluminum Oxide is fused from high quality bayer aluminum in high temperature. Its hardness is higher but toughness lower compared with Brown Aluminum Oxide. It is characterized by high purity, excellent self-sharpening, efficient grinding efficiency, and low frictional heat. It can withstand acid and alkali erosion, with high temperature resistance and good thermo stability.

2. Applications:

· Abrasive tools: grinding wheel; 

· Lapping and polishing non-skid title; 

· Pressure blasting hard abrasives; 

· Refractory industry               

3. Advantages:

a. Use imported Bayer aluminum; assure the high quality of products. 
b. Equipped full line of test method. The laboratory is certified by government Inspection Bureau, that assures its quality stability.
c. Products are classified chemical washed, non-washed, shaped, non-shaped, normal bulk density and high bulk density. All products will be supplied according to customers different requirements .

White Fused Alumina As The Material of Corundum Brick

Q: How much is a thermal brick?
If you really want to buy thermal insulation brick, do not simply look at the price, but also to consider the quality of the product. (a piece of brick in the market basically in 6 yuan, if there is a floating price if it is because of the size of the insulation brick or distance, but floating slightly.)
Q: What is the main component of corundum?
The name of corundum originates from India and is the name of mineralogy. There are three main variants of corundum Al2O3, which are alpha -Al2O3, beta -Al2O3 and gamma -Al2O3 respectively. Corundum is second only to diamond.
Q: Which is good, glazed brick and whole cast glazed brick?
The main advantages of all glazed glazed tiles are that they can be very rich and beautiful in texture and pattern, and they are suitable for family decoration, and can choose patterns according to their own family decoration style. Compared to the glazed tile, it has better pollutant discharge performance, and many pollutants are difficult to penetrate into it.
Q: Expansion ratio of lightweight corundum refractory bricks
Light corundum refractory brick, because of its production methods and the introduction of different additives, there are certain differences in the content of Al2O3, just burn add general light corundum refractory brick and foam and gasification method cannot be made, the content of Al2O3 is generally not more than 99%, with alumina hollow ball manufacturing transfer are corundum brick with high content of Al2O3.
Q: How to improve the induction furnace campaign, from the promotion of refractory life start
According to the workpiece, choose the appropriate hardware castable, corundum brick or refractory bricks, etc.
Q: What refractory materials are adopted in each part of the blast furnace?
Bosh temperature reaches 1600~1650, high alumina brick, corundum brick or silicon carbide brick. The upper hearth tuyere zone near the temperature at 1700~2000 Deg. C, the use of sillimanite brick, corundum and silicon carbide refractory filler, Shi Mozhi. Bottom temperature at 1450~1500 Deg. C, the use of graphite bricks and microporous carbon brick, now also used corundum brick, Gang Yumo brick and synthetic mullite brick.
Q: What is the difference between corundum and high alumina?
The main component of high purity 99 corundum brick is corundum sand,90 corundum brick is mainly composed of corundum sand and a small amount of Suzhou soil, mullite.
Q: Ask for help about the phase of refractory material
Binding phase. The binding phase is the phase outside the main crystal phase or the main crystal phase and the sub crystalline phase. The binding phase can be made up of either a fine crystal or a glass phase or a composite of the two. Such as the combination of magnesia brick, magnesia chrome brick, magnesia brick and other basic refractories in phase is composed of crystal matrix; silica brick, clay brick is made of glass phase in the form. When the matrix is formed at high temperature, the liquid phase is low, and the viscosity of the liquid phase is low and the quantity is large, the production and properties of refractory products are essentially controlled by the substrate.
Q: What kind of rock is corundum produced?
If Ti4+ and Fe2+ containing a small amount of blue, a sapphire; containing six symmetrically distributed acicular rutile or other inclusions in some crystals, can produce six star awn, known as star ruby or sapphire stars, are precious stones. Corundum is vitreous luster with no cleavage, but cracks occur because of the presence of poly twin crystals that are often formed by the base or face of a face. Specific gravity 3.98. Of relatively low silicate igneous and metamorphic rocks and common in alluvial deposits. The U.S. state of North Carolina and Georgia, Russia's Ural mountains, South Africa as the main origin of the transvaal.
Q: What can zirconium sponge do for those industries?
Zirconium metal, also known as sponge zirconium, silver gray metal, the appearance of steel, shiny; melting point 1852 points, sub points, boiling point 4377 density 6.49. Zirconium is easy to absorb hydrogen, nitrogen and oxygen; zirconium has a strong affinity for oxygen; at 1000 DEG C oxygen dissolved in zirconium can make its volume increase significantly. Zirconium is relatively stable in the air; powder zirconium is easy to burn; fine zirconium wires can be ignited by matches; at high temperatures they can be combined directly with dissolved oxygen, nitrogen and hydrogen.
