Description of Brown Fused Alumina for Refractory Use, Sandblasting, Abrasives:

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 of Brown Fused Alumina for Refractory Use, Sandblasting, Abrasives:

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.

If you’ve any enquiries, please don’t hesitate to let us know.

Q:Who knows what is the requirement for fireproofing of interior decoration materials ?: In addition to the underground building, combustion performance level of interior decoration materials inside windowless room , in addition to a class, should advance 1 level based on the original provisions . Library, archives and rooms storing artifacts, ceilings, walls should use class A decoration materials, and the ground should use decoration materials no lower than class B. When high temperature parts of lighting and lighting lamps and lanterns are close to non - grade A decoration materials should be taken, fire prevention measures such as thermal insulation and heat dissipation must be taken. Combustion performance level of materials used for lighting should be no lower than B. Kitchen ceiling, wall and floor should used class a decoration materials.

Q:What kind of refractory materials are used in the intermediate frequency furnace?The domestic boric acid can be used as a lining?, how much is the rate?: Acid, neutral, basic and composite materials are used in intermediate frequency furnace. Domestic boric acid is practicable. The ratio is to determined combined with material, steel (iron) species, smelting temperature, current and other factors

Q:What are the fire resistance ratings of the glass partition?: When the inner structure of the system is steel structure, the fire resistance of which is 30 mins, 60mins or even longer. The partitions in the usual sense are walls that have a distance to the ceiling. The fixed partitions directly touches the ceiling are partition walls which should be required in accordance to the specifications of walls. If the partition is far from the ceiling, the fire protection requirements are relatively low. Partitions which combustion performances are no less than B1 level are safe enough, while partitions of places such as shopping malls have to reach A-level in terms of combustion performance.

Q:Refractory material, refractory brick: High alumina brick is commonly used in high aluminum, LZ-75, LZ-65 and LZ-55, as well as high alumina brick for blast furnace, high alumina brick for hot blast furnace, and low creep high alumina brick

Q:What are the requirements of the performances of brasque refractory?: Physical properties of refractory include structural properties, thermal properties, mechanical properties, usability and operation property. The selection of the brasque refractory must have the following characteristics: 1. properties of not distortion and not melting at sufficient temperatures 2. have the necessary structural strength at high temperatures and does not soften and deform 3. must keep stable volume at high temperatures and will notcrack caused by expansion and contraction 4. will not rapture and flake when temperature is drasticly changed or heated unevenly 5. resistant to chemical erosion of metallic solution, slag and furnace gas, etc.

Q:How many fire endurance grades are the AAA fire resisting shutter divided?: The fire shutter is divided into A / B / C classes. The refractory limits are not less than 1.2 /0.9 /0.6 hours. References to "general technical specification for steel fire resistance rolling shutter door GB 14102-93". 4.3 4.3.1 Classification according to fire resistance time. The common steel fire resisting shutter(see Table 3) The categories of the codes of the refractory time hF1 1.5F2 2.04.3.2 composite steel fire shutter composite steel fire shutter(see Table 4). Table 4 and Category Code refractory time hF3 2.5F4 3.04.4 refractory press time, smoke performance classification 4.4.1 ordinary steel fire anti-cigarette curtain (see Table 5) Table 5 and category code leak smoke refractory time h (20Pa pressure) FY1 1.5 ≤0.2m3 / m minFY2 2.0 ≤0.2m3 / m min4.4.2 composite steel fire anti-cigarette curtain (see table 6) table 6 and category code leak smoke refractory time h (20Pa pressure) FY3 2.5 ≤0.2m3 / m minFY4 3.0 ≤0.2m3 / m min excerpt complete fire shutter when the fire district for fire resistance of 3 hours, the opening portion on the firewall setting fire shutter fire resistance of 1.2 hours. **** Fire resistance of 3.0 hours called premium (fire back surface). "Construction Regulation" is mentioned in setting up a firewall and used as the separation of the fire resisting shutter and the fire?compartments. When taking the fire back surface temperature rise as the fire resistance standard of the fire resisting shutter, the fire endurance should not be less than 3.00h; When taking the fire back surface temperature rise as the fire resistance standard of the fire resisting shutter, the two sides of the roll should have protection of ?closed automatic water spray system, and the duration of water spray system should not less than 3.00h. In summary: The fire resisting shutter can be divided into: Grade, A, B and C looking to adopt

Q:Who knows about roof fireproofing materials?: Roof water proofing materials: synthetic polymer waterproof rolls, high polymer modified asphalt waterproof coiled material, sheet metal, synthetic polymer waterproof coating, one-component water curing polyurethane waterproof coating, penetration crystalline waterproof coating. Secondly, we have to choose materials that are suitable for roof water proofing. The right waterproof materials have better waterproof performance, TS-3B one-component water curing polyurethane waterproof coating is very suitable and the performance is good. Since traditional roof waterproofing materials have requirements on the moisture content of the formation level which should be less than 9%. It is really important to choose which materials to repair leaking roofs. Kitchens and toilets are moisture, the formation levels of buildings are hard to satisfy requirements, thus, waterproof?layer and formation level are easily get separated and are ineffective in waterproofing.

Q:About the market issues of thermal insulation material and refractory material.: In fact, the thermal insulation material produced by the Sichuan-Benniao Hing construction company is very good, you can get the company's information just by inputing the Sichuan-Benniao Hing construction company into Baidu

Q:Who can tell me about the foundry refractory materials?: Such as: neutral, alkalic, acidic refractories. Of course, the raw materials of different materials are not the same. Such as: the magnesia-carbon bricks, basic refractory materials: magnesite(electric?smelting, high-purity)+ crystalline flake graphite+ phenolic resin+ additive (aluminate or silicon powder or silicon carbide powder or high-temperature pitch) and so on.
