Description:

Brown fused alumina is made from Calcined Bauxite. It is hard and tough material, used in manufacturing of grinding wheels (both vitrified and resin bonded) and coated products. These grains are also used for shot blasting and as polishing media. Refractory grade BFA is used as a raw material in the manufacture of high alumina refractory. It is available in grit sizes as per FEPA for abrasive applications and group grits for refractory applications.

 

 Application: 

Resin ceramic abrasive, sand blasting, grinding and polishing, and is widely used in anti-wear runways, high-temperature coating matrix and metallurgy, chemical industry, and other high-level furnace refractories.

Q:What are the models of refractory cables?
NH is the firat letter of "refractory" in Chinese phonetic alphabet; It is V, not W. PVC insulation and sheath; K in KVV represents the control cable. 5 * 10 represents the cable is made up of 5 core cables whose nominal cross section is 10 square milimeter.
Q:How to choose refractory material
The crystalline refractory fiber mainly consists of polycrystalline mullite fiber, the optimum use temperature is 1300 DEG C, and the long-term use temperature of polycrystalline alumina fiber is 1400 DEG C. The service temperature of ordinary refractory fiber is 1150 degrees, and the use temperature of advanced refractory fibers (such as alumina, zirconia, refractory fiber) can reach 1700 degrees centigrade
Q:How much is the duration of fire resistance of the porous brick shale?
This is really a simple question. The temperature should be limited within 1050℃, or it will be scorched. I think 980℃would be acceptable.
Q:What is the offer of fire proofing thermal insulation material?
1. Fire proofing thermal insulation material ceramic fiber paper aluminum silicate fiber blanket/aluminum oxide fiber insulation cotton insulation pipe 15 yuan 2. 1260 ceramic fiber cotton thermal insulation panel thermal insualtion aluminum silicate aluminium oxide fireproofing fibre board 20 yuan 3. non-asbestos high temperature resistant aluminum silicate fiber insulation cotton fire-resistant material ceramic fiber cotton blanket 28 yuan The above prices are from the Internet and for your reference only. Price may vary according to specific circumstances.
Q:Which plant need to make refractory mould?
Q:What's the refractoriness and how to measure the refractoriness?
Bottom each side length is 8 mm and upper side length is 2 mm. Under a certain temperature-rising speed, when heating, refractory's resistance to high temperature from melting is called refractoriness. The properties of cross section into an equilateral triangle and height is 30 mm. When it bends down until the vertex and chassis contact temperature is the refractoriness of sample. It bends due to the influence of its weight. Make the will-measured material into standard pyrometric cone.
Q:Pals who know something about fire resistant material please tell me how many types of refractory material there are
Refractory materials used in special applications include high temperature oxcide, such as alumina, lanthanum oxide, beryllium oxide, calcium oxide, zirconia and other, refractory compounds, such as carbides, nitrides, borides, silicides and sulfides; high temperature composite materials, mainly contain metal ceramic, high temperature inorganic coatings and fiber reinforced ceramics.
Q:Which are fireproofing external wall materials?
According to combustion performance, external wall thermal insulation materials are classified as Grade-A and Grade-B. Grade-A refers to incombustible material and Grade-B combustible material. A few years ago the fire in CCTV building and Shenyang Hotel were caused by Grade-B material. Currently Grade-A material is more commonly uesd and less expensive than Grade-B material. Grade-A material can be divided into thermal mortar, phenolic foam board, rock wool board, foam cement board, etc. Thermal mortar is easy for construction and unexpensive, but it is also easy for faking due tou its simple procesing. It is recommended to find a large factory whihc has gone through the formalities.
Q:How much is the content of boron carbide in refractory material?
furthermore, aluminite powder costs only ¥20,000/ton, and the addition is only 0.1%—2%, or just none; while boron carbide costs ¥50,000/ton.
Q:Who knows about the fire endurance of grade C fire doors?
The fire endurance of grade C fire doors is no less than 0.5 hours. As the key role of family fireproofing, fire doors is particularly important. It can be classified according to the fire endurance and thermal insulation performance: The fire endurance of grade A fire doors is not less than 1.5 hours; that of grade B fire doors is not less than 1.0 hours; and that of grade C fire doors is not less than 0.5 hours. The most important property of fire doors is the fire resistance period.
