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: 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: Can the PE sintering plate dust collector be suitable for dust removal in the coking plant?
Do not know where the coking plant do dust treatment, processing conditions are different, the dust collector is not the same
Q: What is the standard classification of high alumina bricks and high alumina bricks?
High alumina brick is a kind of refractory material in refractory brick products. It is made of refractory clay or other refractory material. It belongs to the product of Si Al System
Q: What is the difference between corundum and high alumina?
The main components of high alumina brick are high alumina bauxite, mullite and partial corundum sand.The difference between them lies in the content of alumina and the alumina refractory products with alumina content higher than 48%The content of Al2O3 is higher than 90%, which is called corundum brick.
Q: High temperature refractory material?
Many kinds of refractory materials, usually by refractoriness level is divided into ordinary refractory materials (1580 to 1770 DEG C), advanced refractories (1770 to 2000 DEG C) and special refractories (more than 2000 DEG C); according to the chemical characteristics into acid refractory material, refractory materials and basic refractory materials. In addition, the refractory material used for special occasions.
Q: What's the size of the fused zirconia corundum refractories for glass furnace? What are the main kilns? How much is the dosage?
The fused zirconia corundum brick is made up of 30% ~ 41% zirconia two in the alumina burden. The main mineral compositions are corundum, zircon and glass phase. The main varieties are fused (or cast) zirconium corundum brick (also known as AZS casting brick) and sintered zirconia corundum brick. Generally speaking, zircon corundum brick means sintered zirconia corundum brick. It is made from alpha -Al2O3, partially stabilized zirconia and zircon corundum clinker, which is prepared by proportioning and molding at 1700~1750 DEG C and then sintered at two. The sintered zirconium corundum brick has a strong resistance to molten glass, and its thermal shock resistance is stronger than that of fused zirconia corundum brick. It is mainly used as lining of glass furnace and induction furnace, as well as steel rolling furnace, slide rail, etc..
Q: What are the main constituents of refractory bricks?
Refractory brick composition is mainly composed of a variety of aggregate or aggregate and one or more kinds of sticky agent composed of mixed powder particles, when used, must be mixed with one or more liquids, mixing evenly, with strong liquidity. Different refractory bricks are different, such as silicon, aluminum, clay and so on:According to the composition of refractory bricks, they can be divided into five major categories, namely, silicon aluminum refractory bricks, basic series refractory bricks, carbon containing refractory bricks, zirconium containing refractory bricks and insulating refractory bricks. Any furnace is not made of only one kind of refractory brick, and it needs different fire bricks to match with each other. The following five categories of refractory bricks are described in detail.
Q: What kind of refractory material will be used in the glass kiln?
The content of ZrO2 in the brick is about 66%, and the bulk density is 3.7g/cm3, which has better thermal stability and anti stripping property. The use of erosion serious investment outlet area and after the parapet wall in the powder melting furnace, observation hole brick and pathway of flame space and roof parapet wall brick, brick burner. But there are also AZS burner brick with mullite brick for brick kiln and transition two side clearance brick etc..
Q: Can the fire clay be reused?
Refractory soil cannot be reused.Clay refractory soil 1, characteristics and uses: Clay refractory brick is a weak acid refractory material, its thermal stability is good, suitable for hot air furnace, all kinds of boiler lining, and flue, smoke room, etc.. 2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.
Q: What problems should we pay attention to in the use of fused zirconia corundum brick (fused zirconia corundum brick) in glass furnace?
Casting, casting mouth often appear shrinkage, brick porosity more, the density is lower, so in the brick wall of glass melting, the shrinkage in the kiln direction, if the nozzle outward, when the brick to erosion is very thin, can cause leakage of liquid glass accident. When the flame space is used in the upper part of the bath furnace, the service life is long, and the glass liquid problem can not happen, so the casting mouth is used outwards, and the service life is prolonged.
