1.Calcined Bauxite Description
A general term for a rock composed of hydrated aluminum oxides. It is the main ore of alumina to make aluminum. Also used in the production of synthetic corundum and aluminous refractories. The bauxite is purified by the Bayer Process. First the ore is mixed with a hot concentrated solution of sodium hydroxide. The NaOH will dissolve the oxides of aluminum and silicon but not other impurities such as iron oxides, which remains insoluble. The insoluble materials are removed by filtration.
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
calcined bauxite is typically calssified according to its intended commercial application,such as abrasive ,cement , chemical l, metallurgical, and refractory .as raw material for use in high alumina and super duty refratory bricks and shapes ,plastics ,castable refratory, motors, gun mixes, ramming mixes, abrasive grains and other products chemical composition .

- Q: What is the common inorganic fireproof and thermal inuslation matertial?
- Ceramic foam insulation board is made from clay tailings, ceramic broken flake and river silt, which is the closed ceramics material with high porosity roasted in high temperature by advanced production technology and foam technology. Products have fire retardant, small deformation coefficient, aging resistance, stable performance, good environmental protection, good compatibility between wall base and plastering layer, good safety and soundness and a lifetime as long as the building itself.
- Q: Can anyone tell me what is A-leve fireproof material?
- What you say is probably palstic! B-level means the fireproof rating is at B1-level because palstic material doesn't belong to fireproof materials. It only is fire?retardant. When wholesaling all kinds of insulation materials and construction, it need tos look at the names. B1-level refers to the fire endurance rating of the fireproof material, which is determined according to the fire resistance of the material. In addition, different parts of the material have different fire endurance ratings! You can download a "Specifications of Fireproof Design for Buildings" for further information!
- Q: What are the models of refractory cables?
- The models of refractory cables: NH-KVV22 copper core flame-retardant PVC insulated and fire retardant control cables with steel belt sheath NH-KVVRP copper core flame-retardant PVC insulated and fire retardant shielding control cables with steel braiding sheath NH-KVVP2 copper core flame-retardant PVC insulated and fire retardant shielding control cables with sheath and steel belt wrapping NH-KVVRP2 copper core flame-retardant PVC insulated and fire retardant shielding soft control cables with sheath and steel belt wrapping NH-KFF copper core fluorine plastic insulated and fire retardant control cables with sheath NH -KFFR copper core fluorine plastic insulated and fire retardant soft control cables with sheath NH -KFFP copper core fluorine plastic insulated and fire retardant shielding control cables with sheath and copper wire braiding
- Q: How to count the construction costs of refractories?
- In winter, the temperature of the the fire-resistant masonry, fire-resistant plastic, sodium silicate, phosphoric?acid castable should be maintained above 5 ℃. Usually greenhouses in which heating facilities are installed to maintain the appropriate temperaturere for the construction environment should be erected in refractory masonry. The temperature around the construction site of the industrial furnace and refractory masonry shall not be lower than 5 ℃.
- Q: What is the classification standard of fireproofing material levels?
- Standard: Class A: Incombustible building material, almost without burning. class A1: Non-combustible, no open flame,class A2: Non-combustible,it needs to measure smoke and be qualified. Class B1: Nonflammable building material: Nonflammable materials have good flame resistance function. when it contacts open fire or is under high temperature, it's difficult to burn and be spreading rapidly, and will stop burn after removing the combustion?source. Class B2: Combustible?building?materials: Combustible materials have good flame resistance function. when it contacts open fire or is put in the air at high temperature, it will immediately burst into flames, and easily result in the spreading of fire, such as wooden column, timber roof truss, timber beam, wooden stairs, etc. Class B3: Inflammability building materials, without any flame resisting effects, easy to burn, and has large danger of fire disaster.
- Q: What is the particle size of boron carbide for refractories?
- 0.3-0.5% is OK, but also with other additives, such as aluminum powder, silicon powder, magnesium alloy powder and so on. To achieve good results.
- Q: What are the types of refractory sealant?
- 1. The characters of sealant for construction According to the characters, sealant for buildings are classified into caulk, sealants and construction sealant in China; They are named in accordance with the function and different basepolymeters. In the relevant standard for products,
