Introduction
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 thereby 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
1.Applications
Raw bauxite is typically classified according to its intended commercial application,such as abrasive ,cement ,chemical, metallurgical, and refractory .as raw material for use in high alumina and super duty refractory bricks and shapes ,plastics ,castable refractory, motors, gun mixes, ramming mixes, abrasive grains and other products.

- Q: What's the texture of refractory for the hearth of reverberatory?furnace? ?
- The long-term usage temperature of ceramic fiber is between 950-1260 degrees.
- Q: How to divide fire rating of decorating materials ?
- Decorating materials shall be divided into four levels according to combustibility. Level A: noninflammability; B1: difficult-flammability; B2: combustibility; B3: inflammability.
- Q: How long is the duration of fire resistance that fireproof window of level B can endure?
- The duration of fire resistance: fireproof window of level A shall not be less than 1.5h, while level B shall not be less than 1.0h. The frame of both fire proof windows A and B are made of steel, and the glass, not less than 26mm, is composite insulation fireproof glass. Monolithic fireproof glass window is neither B fire proof window nor A fire proof window, but non insulated fire proof window.
- Q: How long usually will the A-level fireproof materials prevent the flame?
- A-level fireproof materials refer to the materials which are made of non-combustible materials, it is a different concept from fire resistance. non-combustible elements: Components are made of non-combustible materials. Non-combustible materials refer to materials that will not burst into flame, and burn as well as be carbonized when affected by fire and high temperature in the air. Fire resistance: Having a fire resistance test on any building components -----according to the standard time-temperature curve. This period starts from the time when affected by fire and ends up with losing the ability to support or to insulate fire or the integrity of the components. It can be expressed in hours.
- Q: What refractories have good mechanical property resistance and heat expansion and cold contraction property?
- Explain that where you use it for and what requirements you have. Follow-up: I use it in metallurgical furnaces with the features of strong stirring and acidic residue.
- Q: The classification of fire-resistant material
- Refractory material cna be divided into common and special fire proofing material. Common fire proofing material can be sub-divided in to acid fire proofing material, neutral fire proofing material. and alkaline fire proofing material according to chemical properties. Special fire proofing material can be divided into high temperature oxide refractory, refractory compounds and high temperature composite materials according to the composition. In addition, it also can be divided into common refractory products (1580 ~ 1770 ℃), high-grade refractory products (1770 ~ 1770 ℃) and super refractory products (above 2000 ℃) according to the strength . According to the shape, it can be divided into block (standard brick, special-shaped brick, etc.), special shape (crucible, sagger, pipe, etc.), fibrous (aluminum silicate, zirconia and boron carbide, etc.) and irregular shape (refractory clay, refractory castable, ramming material and so on). According to sintering process, it can be divided into sintered product, fused cast product and melting jetting product.
- Q: what's the fire endurance of fireproof?panel?
- Fire endurance of fireproof?panel is 3 hours, for example, 12 mm non-asbestos fiber reinforced calcium silicate board, fireproof?panel, two single 75 keel. through the monitoring of national fireproof construction materials quality supervision center, it's security and refractory time will reach over 3 hours. Fireproof board, also called fire endurance board, scientific name is thermosetting resin impregnated paper laminated wood.
- 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: Who knows what material is in the center of fireproof rolling curtain?
- made of inorganic super fireproof rolling curtain: Glass fiber cloth ceramic fiber cloth (reinforced stainless steel wire) ceramic fiber blanket aluminum foil cloth. Hope my answer will help you.
