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.

Applications

calcined bauxite is typically calssified 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 refratory bricks and shapes ,plastics ,castable refratory, motors, gun mixes, ramming mixes, abrasive grains and other products.

Q:Who knows about the fire endurance of A grade fireproofing glass doors?
Fire doors and windows are divided into grade A, B and C according to the real national situation, also the minimum fire endurance has been stipulated, namely, the minimum fire endurance of grade A is 1.50 h, that of grade B and C are 1.00 h and 0.50 h respectively. There are wooden fire doors and steel fire doors. The main purpose of it is to reach the time that fire resistance should last. But door?closers are required to install. The fire endurance of A grade wooden fire doors should be no less than 90 min, and that of B grade fire doors should be no less than 60 min, that of C grade fire doors should be no less than 30 min! ! !
Q:What is the limit of fireproof rolling shutter?
According to the national standard 14102-2005 GB standard, the provisions of 14102-2005 GB specify that: According to provision 14102-2005 GB: 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:What's the fire?retardant material of roller shutter fire resistance door ?
I am happy to answer this question. Fire resistant rolling shutter door is generally filled with aluminum silicate fiber cotton inside. fire resistant rolling shutter doors are divided into special inorganic fireproof rolling shutter door and steel fire resistance rolling shutter door. The former has better fireproof?performance, but the later has certain wind load resistance and can be installed outdoors.
Q:What are the differences between intensive refractory busway and other busways?
Compact busway is named after its structure, especially referring to busway which is closely laminated between phases and between phase and shell and use thin insulating material to achieve the insulation result. Fire-resistant busway is named after its uses, just as its name implies, for higher fire safety requirements need busway of higher fire resistance level. The structural style of fire-resistant busway can be intensive and of air type, depending on what material it use to resist fire, so there is no direct link between them, but there is a included relationship.
Q:What type of firebrick does TZ-3 represent?
Height is 65mm, length is 230mm, and width is 114mm, that is the t-3 firebricks which meet the national standard.
Q:What antioxidant will be used in refractories?
Antioxidant: Si, Al, Mg, Ti, AlSi, AlMg, SiC, TiC, ZrC and these metal nitride, boride. Sintering agent: different mechanism, Cr2O3 to promote the sintering of alumina;CaO/MgO style promote ZrO sintering;Siliceous ramming material to add boron bottles, magnesia coating and clay, etc.
Q:How long does it take for refractory cement to solidify?
1. First you should be aware of the concepts of condensation and condesation time. Refractory cement belongs unshaped refractories, which when added water or liquid binding agent to mix, the agitation material will gradually lose thixotropy or plasticity and become in a state of solidification, thus is solidified. The time needed to finish the process is called solidification time. The whole process is divided into initial and final set. When beginning to lose plasticity called the initial setting, when called plasticity completely lost the final setting. 2. For refractory cement, the solidification time depends on the matching of the material and the parts and using methods. Under normal circumstances, in order to meet the requirements of time of construction, the initial set time should be no shorter than 40min, and the final set time should be no longer than 8H 3. There are also some exceptions. When refractory cement is used for spraying and injection operation together with other refractory castable, the set time is required as short as possible, sometimes flash set is required to prevent the occurrence of peeling or collapse of the spraying layer.
Q:How to make fire resistant materials for building stoves
Grand Theft Auto Vice City plus life code is what?
Q:Are fire materials poisonous after burning?
High temperature oxide materials in refractory special applications, such as aluminum oxide, lanthanum oxide, beryllium oxide, calcium oxide, zirconium oxide, refractory compounds, such as carbides, nitrides, borides, silicides and sulfides; high temperature composite materials, including metal ceramics, high temperature inorganic coatings and fiber reinforced ceramics.
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!
