1.Structure of Calcined Bauxite Description
Bauxite (aluminous soil; Bauxite) is also called the alumina or bauxite, main ingredients are alumina, hydrated alumina containing impurities, is an earthy mineral. White or gray, brown and yellow or light red by iron.
2.Main Features of the Calcined Bauxite
Calcined bauxite is one of the principal ore of aluminum. Calcined bauxite contains hydrous aluminum oxides and aluminum
hydroxides, formed through the laterization of aluminous rocks in tropical and subtropical areas .Calcined bauxite is obtained by calcining (heating)superior grade bauxite at high temperature (from 85OC to 1600C) .This removes moisture there. By increasing the alumina content,compared to an alumina content of about 57%to 58% in raw bauxite, calcined bauxite has an alumina content of 84%to88%.The heating is carried out in rotary kilns.
3.Main usage of the Calcined Bauxite
(1) aluminium industry. Used in national defense, aerospace, automotive, electronics, chemical industry, daily necessities, etc.
(2) precision casting. Alumina clinker made after the mould precision casting processed into fine powder. Used in military industry, aerospace, communications, instrumentation, machinery and medical equipment department.
(3) is used for refractory products. High bauxite clinker refractoriness is as high as 1780, chemical stability strong, and good physical properties.

- Q:Refractory factory grinding brick dust harmful to the body?
- The effect is very large and belongs to lung disease.
- Q:Is the refractory reached British BS standard and used for cables in China at present ceramic silicone rubber?
- The texture should be designed according to the British relevant BS standard; crosslinked polyethylene or ethylene propylene rubber under 6600V to 19000 / 33000V is not necessarily ceramic silicone. The rated voltages of a small amount of smoke and corrosive gases from 3800 & # 47 when the BS 7835-2000 is affected by fire.
- Q:What is the material of fire resistant glass reinforced plastics grating?
- What is the material of fire resistant glass reinforced plastics grating?
- Q:What is the limit of fireproof rolling shutter?
- Fireproof rolling shutter door is a kind of fire protection and heat insulation facility which is suitable for the large openings of buildings, having a certain effect on the design and installation. Fire shutter doors are widely used in fire partition of industrial and civil building. It can effectively prevent the spread of fire, to protect the safety of life and property. It is an indispensable modern building fire facilities. According to the national standard 14102-2005 GB standard, the provisions of 14102-2005 GB specify that: If fire resistance limit of fire resisting shutter is no less than 3 hours, it is AAA fireproof rolling shutter. Therefore, the fire resistance limit of AAA grade fireproof rolling shutter should be 3 hours.
- Q:Which fireproofing materials factory is the best in Xiangyang?
- Of course, it is "Lvchuang Construction Energy Saving Engineering Co., Ltd." in Xuzhou, which main products are A-level fireproofing thermal insulation boards. It has many projects. B1-level fireproof materials are polyphenyl boards, extruded sheets, phenolic foam boards, Polyurethane board, sea capacity building energy efficiency module. Flame retardant has been added to the sea capacity building energy efficiency modules which has a B1-level fireproofing performance. You can also add expanded glazed hollow beads to them if you are worried about the security.
- Q:What's the refractory material?
- Frequently used refractory material: AZS brick, corundum brick, direct-bonded?magnesia-chrome?bricks, carborundum brick, silicon nitride bonded silicon carbide brick, nonoxide refractories like nitride, silicide, sulfide, boride and carbide, and oxide refractories like calcium oxide, chromium hemitrioxide, alumina, magnesium oxide and beryllia. In general, the refractory material include the above. For more information, you can ask for specific advice.
- Q:Who knows the external wall thermal insulation materials fire rating requirements?
- 1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 Level A insulation material is only for fireproofing, but its thermal insulation performance is not better than organic XPS \\ EPS and other materials. I feel the best insulation materials should be modified phenolic board, which can keep insulation and fireproofing, but the unit price is very expensive. Insulation materials in the domestic market have some disadvantages, it is better to considere the materials within the acceptable range in the building needs.
- Q:What kind of refractories do the anode baking furnace use?
- Usually the clay refractory bricks will be able to meet the requirements
- Q:How to hang the suspended brick in the refractory masonry?
- First you can fasten the girder and the suspended brick with screws, and then move them to the specified location by a crane. You can contact the refractory plant in Shanshan mountain, Ningxiang Countym, Hunan Province at 0731-7150098.
- Q:what is the specs of thermal insulation refractory slab ?
- it is produced in accordance with scientific formula by using asbestos, glass fiber and potclay . it has strong tension strength capable of withstanding 1400 degrees Celsius, specifications!: 1.5DD20 (mm)
