Item


Calcined Bauxite High Purity of Al2O3
 
Product Description 
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.
 

Size 
 

0-1mm,1-3mm,3-5mm,200mesh,325mesh,or as buyer's request.
 
Application
1.Aluminium metallurgy.
2.Precision casting/Investment casting: bauxite grog fines can be made into mold for precision casting.
3.Refractory: high alumina bauxite's refractoriness can reach 1780°C.
 It is charactered by good chemical stability and mechanical performance.( low Fe2O3)
4.Aluminium silicate refractory fiber: The high alumina bauxite grog can melt under2000°C-2200°C in the electric arc furnace.     After a series of processing, it can become aluminium silicate refractory fiber, which can be made into fiber blanket,plate,cloth.
5.Mixing magnesia and bauxite grog with binders to pour the molten steel ladle for better overall lining performance.
6.Producing bauxite cement.
7.Abrasives.
8.Ceramics industry.
9.Chemistry industry for all kinds of aluminium compound.

Q:Where do China and foreign countries do more refractory materials?
The domestic production of refractory materials base in Henan Xinmi, Xinmi has a lot of production of refractory material factory, Zhengzhou gold refractories plant is relatively large, there is a need to go to visit the factory.
Q:What are the types of advanced refractory?
Divided into ordinary and special refractory two categories. Common refractories by chemical properties into acidic, neutral and alkaline. Special refractory are divided by the high temperature oxide, refractory compounds and high-temperature composite materials by its compositions. according to refractoriness it can be divided into ordinary refractory products (1580 ~ 1770 ℃), advanced refractory products (1770 ~ 2000 ℃) and premium refractory products (2000 ℃ above). The article can be divided into blocks (standard bricks, shaped bricks, etc.), special shape (crucible, sagger, pipe, etc.), fibrous (aluminosilicate, zirconia and boron carbide quality, etc.) and irregular shape (refractory clay, pouring materials and ramming mixes, etc.) According to the sintering process is divided into sintered products, cast products, melt blown products. The appearance is shaped or amorphous according to pH it can be divided into acidic, neutral and alkalinity according to basic operation mode, there are castable refractory ramming spraying materials, impressionable plastic material, coating. according to different components, there are clay, high alumina, corundum, spinel, magnesia, magnesium, calcium, magnesium aluminum quality,magnesia-chrome, silicon, etc.
Q:How to make use of waste refractory materials whose main elements are alumina and mullite?
Crushing and pressing refractory bricks, or refractory parts . Such as welding positioner tracks use disposable tools.
Q:Does anyone know the characteristics of refractory for glass kiln?
Refractory is a kind of non-metallic material with refractoriness not less than 1580 ℃, which has better thermal shock resistance and chemical erosion resistance, low heat conductivity coefficient and low expansion coefficient. Refractoriness is the centigrade temperature of refractory cone specimen wiyhout any load resisting high temperatures without melting down Refractory is widely used in industries like metallurgy, chemical, petroleum, machinery manufacturing, silicates, power, etc., which is mostly used in the metallurgical industry, accounting for 50% to 60% of total output.
Q:What is refractory aggregate?
Refractory aggregate is fire-resistant product improved with low temperature binder, chemical compound and normal temperature strength.
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:Which manufacturers have the best fire-proof materials with light weight?
Recommend Hubei Boyuejia Industrial Co., Ltd. It is a specialized high-tech enterprise that integrates research and development, production, sale and installation of new lightweight fireproof partition panel, partition panel, new partition panel and mechanical equipment. Products are lightweight, fireproof, waterproof, sound insulation, thermal insulation, fracture resistance, anti-permeability, environmental protection, strong constitutive property (dense humidity) and other superior performances. It can be widely used in all types of lightweight wall panel of all kinds of buildings, and is one of the preferred materials of plant, residence, hotel, office building and public buildings.
Q:What are the fire endurance requirements of class A fire resistant door ?
The fire endurance of class A fire resistance door is 1.5H, but also depends on the product quality. The filling material of class A, B, C fire doors is the same, new fireproofing material-- perlite. The difference is their thickness. The general structure is: surface panel, fireproof board framework (filled with perlite) fireproof board panel. !
Q:Which one is better, fire-resistant wood or steel?
Rebar would weaken and quickly collapse in the fire, and the fire resistance of a heavy log is much better than steel. In many ways, the fire resistance of a large log is equal to reinforced concrete. The heat transfer capacity of wood is 400 times smaller than steel, 8.5 times smaller than concrete. When burning, wood will form a layer of carbon in the surface, and as long as the cross-section of the timber is over a certain size, this layer of carbon it will become an excellent flame retardant layer to protect the interior of the wood from burning. So the United States and Japan and other European countries allow and encourage the use of wood structure with a large section (beam column of 8 inches or more) to construct public buildings without the need for fire treatment applied to wood surface. I hope my answer will be helpful to you.
Q:What are the material requirements of class A fire resistant door ?
It must meet standards of the national regulation. You may search on Baidu.
