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.

- Q: How to understand qualitative and qualitative refractory materials?
- Such as amorphous refractory castable, referred to as bulk loading, cast material, ramming material, refractory clay etc., utensils and other special products. Amorphous refractory material products, refractory heat insulating bricks and experimental and industrial crucible, spraying materials, such as burning bricks, electric melting brick, turn it into required shape and process heat treatment in where it is used.
- Q: What is acid refractory material?
- In fact, with the content of zirconia refractory multiple theory should also be acid refractory
- Q: What refractories are accessible with ease in daily life?
- Refractory mortar. Thermal insulation refractory materials include diatomite products, refractory castables, monolithic?refractories, carborundum bricks, gun-mix refractories, semi-silica bricks, borides, beryllia, silicide, calcium oxide, high alumina refractory brick, refractory coatings, corundum bricks, fireclay?bricks, silicon nitride bonded silicon carbide bricks, chromium hemitrioxide and other refractories. What refractories can be found mostly in the market? Common refractories. Common refractories include silica bricks. The mostly used unshaped refractories include fettling, ramming refractories, castable refractories, plastic refractories, refractory clay, gun-mix refractory, sling refractories, refractory coatings, lightweight refractory castables, stemming etc. The mostly used insulating refractories include diatomite products, asbestos products, insulation panels, etc. The mostly used special refractories include AZS bricks.
- Q: Who knows the fire rating of fire?partition with steel stud?
- Cement board wall of steel stud: it is used for walls with ceramic in kitchens, restroom, disinfect room, etc. If single-sided tile is made, cement pressure plate can be used on one side. Gypsum board is used on the other side. Fire?rating is A1. CaSo4.2H2O is molecular structural formula of gypsum which contains 20% water, crystal water and free water. When 10% water slowly evaporates on the flame surface, there is still 10% crystal water. Itself is grade A fire retardant material. 1 hour. It is in line with the fireproof test standard of national building materials. It can reach up to 4 hours at most.
- Q: What is the use of refractory?
- It is equivalent to a protective layer. It can be used to protect structural materials from being direcctly attecked by high tempereture or internal gases. General structural materials are steel, so the main function is resistant to fire and high temperature. In literal meaning, refractory is a fireproof material. Steel is easily deformed and wore. Structural materials can not directly touched with solid and liquid. Refractory materials are generally used as a protective lining of structural material, so it is necessary to be protected.
- Q: Which kind of refractory floor is easy to use? ?
- Recommend: Yong Wei fireproof board Henan Yong Wei Anfang Co., Ltd., located in Qinbei industrial agglomeration area, Qinyang City, Henan Province, was founded in 1995. It strated from the initial one fire decorative plate production line. After years of development, it has become the biggest fireproof decorative board production base with 25 fireproof board production lines.
- Q: Can anyone say something about what A-level fire-proof decorative material is?
- The major products are material monomer A-level and composite A-level, now a lot of B-level material is wrapped in calcium silicate board. The foam cement overall composite is level A, such as phenolic aldehyde composite, as well as some of the foam paddings, monomer A-level includes rock wool, ultra-thin insulation panel and the like. But there are few products with real sound A level qualification. Many manufacturers are playing the edge ball with A-level fire rating examining reports and B-level system detection reports and records, but this situation will not last long, which will soon be clear.
- Q: What is the mechanism of the errosion of the iron to the refractories?
- For example, the effect of the iron oxide: Mo corundum given temperature Fe2O3 solid solubility limit of the solid solution formed of corundum stone high solubility than the solid solution Mo Mo corundum lattice shape so Fe2O3Al2O3-SiO2-based material starts melting temperature of the system or the content of Al2O3 and Al2O3 / SiO2 ratio off Al2O3 / SiO2 & lt; 2.55 starting melting temperature of 1380 ℃ when Al2O3 / SiO2 & gt; 2.55 start melting temperature is increased 1460 ℃ and with its Al2O3 content increased gradually to increase the original atmosphere Fe2O3 original FeO off the solvent into the glass phase and the system starts melting temperature drops do not fall to 1240 ℃ 1380 ℃. Lower the melting point, increase the erosion, and reduce the life span.
- Q: Which refractory is better for building 1500 degree kiln ?
- The top and wall use alumina hollow ball brick. If it is cubic kiln, the kiln bottom should use heavy corundum brick. If it is continuous kiln, burning zone should use alumina hollow ball brick, burning zone seal and kiln car face brick. If it is pit furnace, curved seal should use heavy corundum brick, and furnace wall and top should use alumina hollow ball brick. That depends on what kind of kiln it is. Curved seal and kiln car should use heavy corundum brick. You can add me friends to have further talks.
- Q: What's the A grade fireproofing material?
- 1. fire-proof plate; 2. fireproof wooden door; 3. fireproof wooden window frame; 4. fire resisting shutter; 5. fireproof and mothproof wood; 6. fireproof glove compartment; 8. fire?retardant?coating; 9. fire-proof?sealing?material.
