1.Structure of Calcined Bauxite Description
Bauxite (aluminous soil; Bauxite) is also called the alumina or bauxite, main ingredients are alumina, hydrated alumina containing impurities, is an earthy mineral. White or gray, brown and yellow or light red by iron. From 4 to 3.9 g/cm3 density, hardness, 1 ~ 3 is not transparent, very brittle. Very difficult to melt. Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution. Mainly used for aluminium, refractory material.
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
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 refractoryiness can reach 1780oC. It is charactered by good chemical stability and mechanical performance.
4, Aluminium silicate refractory fiber, The high alumina bauxite grog can melt under 2000oC to 2200oC in the electric arc furnace.After a series of processing, it can become aluminium silicate refractory fiber, which can be made into fiber blanket, cloth, plate and so on
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.

3). Q: How can I get some samples?
A: Please connect me for samples
4). Q: Can the price be cheaper?
A: Of course, you will be offered a good discount for big amount.
- Q:Physical and chemical indicators of various refractory.
- please read"Refractories Standard Series" for refernece, general business standards are higher than the national standard.
- Q:which kind of fire?bulkhead is better?
- General business fire endurance of two products are 3 hours. Organic fire bulkhead's main ingredient is organic material, which can be used in anti-corrosion and fireproofing cable tray. Inorganic fire?bulkhead's main ingredient is inorganic material, which mianly play a role of fireproofing. It's main ingredient is inorganic material, so it can't be used in acidproof and alkali resistant projects. Of course, the price of same amount organic fire?bulkhead in general is more expensive than the inorganic fire?bulkhead.
- Q:What are the additives and recipes of refractory?
- You can try FDN.
- Q:Does the refractory material used in steelmaking all refer to refractory brick?
- It includes not only refractory brick but also unshaped refractory; while the foaming?agent, ladle filler sand and deoxidizer are not refractory materials but ferrous metallurgy auxiliary materials.
- Q:Does the aluminum silicate thermal insulation material fireproof?
- How does its fireproof?performance? this is the material that the decoration master worker recommands to me, how do you think of it?
- Q:How to do environmental impact assessment for refractory Co., Ltd.
- 1, first of all, the EIA unit and the construction party signed the EIA contract. The contract is only legally valid. Generally speaking, the contract will indicate that the first payment has been received before the work begins.2. Collecting information. This is a very important link in the EIA, which is directly related to the quality of the eia. There is a great variety of data,Generally, the construction party will write a list of environmental impact assessment information.
- Q:Application of refractory materials in petroleum industry
- Our natural gas transportation, chemicals, equipment, packing, safety, insulation, and even building materials are available.
- Q:What does refractory mean?
- Ordinary refractories are often used brick, semisilica brick, clay brick, high alumina brick, magnesia brick etc..Special materials often use AZS brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials. Often used insulation refractories are diatomite products, asbestos products, insulation panels and so onUnshaped refractory materials commonly used are fettling, refractory ramming material, refractory castable, refractory plastic material, refractory clay, refractory gunning, refractory cast material, fireproof coating, lightweight castable, mud etc..
- Q:Which basic refractory is better?
- The following companies are good: 1, Xuzhou Reka Casting Material Co., Ltd. Address: No.22-2 Luoshan Road, Economic and Technological Development Zone, Xuzhou, Jiangsu. 2, Golden Triangle Refractory Plant, Xinmi, Henan. Address: Ganzhou Street, Litang Village, Xinmi City, Henan. 3, Zibo Sun Refractories Co., Ltd. Address: Wujia Village, Shangjia Town, Zichuan(Wenchang Lake) District, Zibo City, Shangdong.
- Q:Why does refractory need to add coarse firstly and then add fine aggregate?
- Binding agent can wrap particles and improve binding effect.
