Introduction of Calcined Bauxite A

 

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 of Calcined Bauxite A

 

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

Q:What effect does aluminium powder play in refractory bricks?
Aluminum powder is the main temperature resistant material ~ ~ ~ ~!
Q:What is the material composition of the new fire-resistant coating?
New fire-resistant coating generally consists of base material, dispersion media, flame retardants, fillers, additives (plasticizers, stabilizers, waterproofing agents, moisture, etc.). (1) Base material is the basis of the composition of the coating, and it is the main film-forming substance, playing a decisive role in coating performance . For fire-resistant coating, its base material must be capable of matching with the flame retardant to constitute an organic fireproofing system. The base material commonly employed at home and abroad includes inorganic and organic film-forming material. Inorganic film-forming materials include silicate. Si03, K2 Si03Na2 Si03), silica and phosphate [Al. (HPO.). ] ect. There are a wide range of organic film-forming substance, usually flame retardent organic synthetic resins, such as phenolic resins, halogenated alkyd resins, polyester, halogenated olefin resins (such as vinyl chloride resin), amino resin (melamine resin, urea resin, etc. ), tar-based resins, furan resins, heterocyclic resins (e.g., polyamide-imide, polyimide, etc.), organic elements resins (e.g. silicone resin), rubber (halogenated rubber such as chlorinated natural rubber) and so on. There are numerous latex taking water as solvent. www.hc3600.
Q:What refractories can withstand high temperature above 2100 degrees?
You can refer to advices from the first one coupled with the second one.
Q:Can anyone tell me what is the material of which the mould for refractory is made?
It is ordinary steel mould and it should not rust
Q:What are the main characteristics of the sic refractories?
1. The usge temperature of silicon carbide refractory is generally 1760 ℃ 2. The silicon carbide refractories can withstand the dramatic changes of temperature and have a good thermal shock resistance performance. To prevent the cracking or breaking of lining refractories. 3. Under the conditions of high or low temperature, it can withstand a certain compressive stress. 4. Under the conditions of high or low temperature, it can withstand friction. 5. It can withstand the huge hydraulic pressure or buoyancy of the metal. 6. It can also withstand the effect of furnace gases to prevent the infiltration of other refractories and reactions.
Q:How many fire endurance grades are the AAA fire resisting shutter divided?
According to the fire endurance, the fire doors can be divided into Class A, Class B and Class C fire doors with the fire resistances are not less than 1.20h, 0.90h and 0.60h. Even the fire resistant level of B can also use the first rate fire resistant door.
Q:What material is refractory material?
Basic refractory materials, basic refractory, CaO, basic, MgO style alkaline earth oxide. The refractory materials mainly refers to magnesia refractories, dolomitic and lime refractory refractory. Main categories: (1) strongly basic magnesite brick, magnesia carbon brick, limestone and dolomite brick refractory materials;(2) alkalescent magnesia chrome refractories, forsterite refractory, magnalium and magnesia-chrome spinel refractory, basic refractory materials, high-temperature caustic slag, alkaline solvent resistance, strongly acidic slag flux or acidic refractory. The reaction is mainly used in steel furnace such as colour metal smelting furnace and cement kiln.
Q:Refractory materials are needed for casting metallurgy.
High quality refractory materials can not be separated from the process of smelting metal and casting moulding, because the quality of melting furnace, iron / steel ladle directly affect the chemical composition of the metal liquid, and exert irretrievable influence on comprehensive quality of castings. Classification of refractory materials used in foundry smelting process: refractory brick, siliceous brick, high alumina brick, corundum brick, magnesia brick, magnesia brick, magnesia carbon brick. Unshaped refractory materials: ramming material, castable, refractory cement, silica, magnesia, coating material and light insulation material etc.
Q:What are the applications of refractory busway?
Is an ieal power supply equipment for modern large and medium-sized enterprises, high buildings, the introduced projects, experimental base and other places.
Q:What is the principal part of silicious refractory material
blast furnace hot blast stove and ceramic tunnel kiln vault, etc., the softening temperature under a fixed load is high (1690-1710 degree), glass melting furnace, lightweight silica bricks and generally the silicon dioxide is greater than 93% and used above the 600 degree. I had undertaken to complete the 50,000 tons over two advanced silica brick production line design. It is a typical acidic refractory. At present, it is mainly used to coke oven which the masonry operating temperature is higher than 600 degree, with good acid resistance of slag erosion, including silica brick, good thermal conductivity, high thermal vibration stability, product with fused quartz, close to its refractoriness silicious refractory SiO2 which is as the main component of refractory products.
