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.

Q:What are the grades of refractory exterior wall thermal insulation materials?: Classification of fire rating of extrior thermal insulation materials 1, According to national standard GB8624-97, the combustion performance of building materials are divided into the following grades A level: Incombustible building materials: Materials hardly burn. B1 class: Flame-retardant building materials: Flame-retardant material has good flame resistance. In case of fire in the air or at high temperature, it is difficult to catch fire and the fire will not spread quickly. And when the combustion source is removed, the burning will stop immediately. B2 Class: Combustible building materials: Combustible materials have a certain flame retardancy. In case of fire in the air or at high temperature, it will immediately burst into flames and it is easily to spread fire, such as wooden column, wooden roof truss, wooden beams and wooden stairs, etc. B3 level: Inflammable building materials: It has no flame retardant effect, and it is extremely inflammable, and the risk of fire is high. Classification of exterior wall thermal insulation materials according to fire rating: 1. Thermal insulation materials with A-level combustion performance Rock wool, glass wool, foam glass, foamed ceramic, foam cement, hole-closed perlite, etc. 2, Thermal insulation materials with B1-level combustion performance: Extruded polystyrene board (XPS) after special treatment / polyurethane (PU) after special treatment, phenolic aldehyde, gelatine powder polystyrene granule, and etc. 3. Thermal insulation materials with B2-level combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.

Q:Does anyone know what is a lightweight refractory material?: Light weighted castable is one of the kind.

Q:what is the common materials for home fireproofing material?: 1, lumber core 2,decoration panel 3 , plywood 4 density board 5,chipboard 6 fireproof?panel, 7.gypsum board Hope to adopt my opinion

Q:How can the furnace be replaced after the gasifier or water wall is replaced with refractory material?: The simplest is to find a refractory construction unit, should provide you with oven curve.

Q:What's the refractory material?: Main components of basic refractory are magnesium oxide and calcium oxide, and magnesia brick is commonly used. For the magnesia brick with magnesium oxide content of more than 80%-85%, it has good resistance to basic slag and scum, and it has higher refractoriness than that of the clay brick and silica?brick. It is mainly applied to the open hearth furnace, oxygen-blown converter, electric furnace, non-ferrous metal smelting equipment and some high-temperature devices.

Q:What refractories are accessible with ease in daily life? This material is suitable as a disposable mold and crucible for melting brass.: Common red?brick and refractory brick.

Q:What kind of refractory materials should be used for the intermediate frequency furnace to smelt manganese?: I am not quite clear. But you should take two aspects into consideration, namely, no pollution and strong durability.

Q:What are the electrical fire protection materials?: Inorganic binder: Water glass, gypsum, phosphate, cement, etc.; Refractory mineral filler: Alumina powder, calcium carbonate, asbestos, perlite, cornstarch; the main purpose of electrical fire prevention board is to prevent fire and heat. The heat conductive plate will conduct electricity, leading to good equipment insulation and large superheating surface! ! ! ! Hope my answer will help you.

Q:Who knows the texture of fire-proof wooden door material?: The so-called fire doors are only posted a layer of fireproof material. Door selection still depends on the timber inside. The simplest way is to see the weight value, fireproof material layer, and they are generally paint-free doors. with fireproofing function..

Q:Who knows about the types of Dalian thermal insulating and refractory materials?: (1) rock wool board: the heat conductivity coefficient is 0.041-0.045. It is fire retardant, has a great temperature absorption while a poor thermal insulation performance. (2) glass wool: it is simple in construction and free in cutting. It has advantages of antibiosis, mould proof, aging resistance and anticorrosion, and can ensure a healthy environment. It has a low hygroscopicity and a stable physical property. (3) expanding polystyrene board(EPS board): thermal conductivity: 0.037-0.041, it has a good thermal insulation performance, cheap price but a poor intensity. (4) extruded polystyrene board(XPS board): thermal conductivity: 0.028-0.03, it has a better thermal insulation performance, high intensity, moisture resistance while it is expensive, and requires surface treatments during construction. (5) gelatine powder polyphenyl granule heat insulating slurry: heat conductivity coefficient: 0.057-0.06, it has a good flame resistance while a poor thermal insulation performance, as well as has high construction requirements and can be recycled. (6) polyurethane foam: heat conductivity coefficient: 0.025-0.028, it has advantages of waterproofness, thermal insulation, high intensity, high integrity, and good integrity, but it has a poor fireproof?performance and is more expensive. (7) rigid polyurethane: heat conductivity coefficient: 0.018-0.023, it has advantages of low heat conductivity coefficient and good thermal performance. When the unit weight of rigid polyurethane is 35 to 40kg per cubic meters, it is equivalent to half of the EPS. It is the one with the lowest heat conductivity coefficient among all the thermal insulation materials. (8) perlite slurry: heat conductivity coefficient: 0.07-0.09, it has advantages of fire and high-temperature resistance, and high water absorption but is poor in thermal insulation.
