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.

If you’ve any enquiries, please don’t hesitate to let us know.
- Q:what textures of furnace refractories are good?
- First, it depends on the kiln. If it is the cubic kiln, the top and the wall portion should use alumina hollow ball bricks. The bent seal and kiln car use heavy corundum bricks. If it is the consecutive kiln, the burning zone shall all use the alumina hollow ball bricks, and both the burning zone bent seal and the brick kiln car bent seal use the heavy corundum bricks. Ifit is the pit furnace, furnace walls and roof use the alumina hollow ball bricks, and the bottom of the furnace use heavy corundum bricks.
- Q:The manufacturing technique of refractory material
- Melt blowing method is to melt the ingredients first, In addition, hiphotos, organic impurities, to be mixed, add sulfite pulp waste liquid into magnesia billet , ensure the accuracy of the product dimension. The products are mainly used for light refractory. then dry and fire with sintering to reduce the firing shrinkage of products, making it disperse into fiber or hollow sphere. The porpose of pre sintering raw material is to Sintering method is pre-sintering part of the raw material into clinker. such as adding binding clay into aluminum silicate blank
- Q:What are the characteristics of magnesium fireproof plate
- Glass magnesium fire resistance plate is fire proof, water proof, noise insulative, heat perservative, non-toxic and tasteless, corrosion proof, easy for construction, can be sawed and nailed and have a wide range of applications as well as long service life. These advantages allow it to be widely used in construction, decoration, fire protection and be the best material to replace is to replace plywoods, MDF, particleboard, gypsum board. It is a key environmental building materials recommended by national association of construction and decoration. 1 superior fire resistance performance. 2 weather fastness, long service life. 3. light weight and anti-seismic 4 high toughness, good impact resistance and compression resistance. 5 green and environmental 6 economical 7 sound insulative and heat insulative 8 convenient for processing and easy for construction.
- Q:what should be paid sttention when buying the refractory?
- First, look at the appearance of the product, it will be better if the surface of product is smooth, if there are the injuries and damages which may influence the use, do not use it. Second, the main characteristics of insulation material is flame resistance, reduce the loss of fire occurred at the time of purchase combustion performance testing products, non-combustible stone wool products are the best. Third, refractory insulation with good hygroscopicity is also very important, it can keep your room drying for a long time , played the role of moisture-proof, and more capillary, the hygroscopicity is better.
- Q:How do refractory materials apply into pyrophyllite?
- Generally speaking, shaped refractory materials require of some powdery materials like spray grouts and iron trough in addition to pyrophyllite brick made of a mixture of pyrophyllite aggregate and powers.
- Q:What 's the highest temperature can magnesium plate glass resist ?
- Glass magnesium plate (commonly known as magnesium oxide or glass magnesium plate) is a magnesium jointing material with stable performance made by adding modifier and processing ternary system composed of magnesium oxide, magnesium chloride. It is a new non-combustible decorative materials comprounded by moderately alkaline fiberglass net as enhanced material and lightweight material as filler. 1, Applications Wall panels, ceiling panels, fire-resistance boards, water-proof boards, boxes, etc.. It can replace wooden plywood panel and be made into dado, door panels, furniture, etc., or into distemper paint water paint to one's need, and can akso be processed into various types of plate surface. It is also applicable to projects undertaken in damp environment such as basement, civil air defense, mines. It can be comprounded with a variety of thermal insulation materials into compround thermal insulation materials 2, Product features: Magnesium plate glass is high temperature resistant, sound absorbing, and capable of preventing water, pests, dampness, corrosion, poison, pollution. Paint can directly be applied to the surface of the plate. Air nails are usable for the plate, to which ceramic tile can also be applied with good pigmentation High strength, flexibility when bending, convenient for decoration. It can be sawed, nailed, and glued. 3, the use of glass magnesium plate: Glass magnesium board is a basic intermediate materials Main occasions for applications: HPL Series: Top of the tunnel ceiling. Decorative plate series: Decoration in hotels, office buildings, residential buildings Board series: Ceiling, partitions, fire proof doors and other products. Sound-absorbing panels: Subway, railway stations, theaters, factories and other public buildings.
- Q:How many fire endurance grades are the AAA fire resisting shutter divided?
- According to the fire endurance, the fire doors can be divided into Class A, Class B and Class C fire doors with the fire resistances are not less than 1.20h, 0.90h and 0.60h. Even the fire resistant level of B can also use the first rate fire resistant door.
- Q:Which refractory is suitable for the tunnel kiln?
- Shuttle kiln refractories requires the good thermal shock properties. Because the tunnel kiln is continuous firing furnace, the temperature in the kiln is long time stable and with little fluctuation. The shuttle kiln is intermittent kiln firing. The temperature in the firing kiln is adjusted by the firing curve. It is with a relatively short time and serious fluctuation. The seal and kiln car take use of the heavy corundum brick. If it is continuous kiln, the alumina hollow ball bricks are used in the burning zone. The seal of the burning zone takes use of the kiln car brick and the seal takes use of the heavy corundum brick.
- Q:Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?
- Strictly speaking, as long as there are solid wood packaging, you need to do fumigation inspection, proved not necessarily used, there are IPPC chapters on it.
