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.
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 .

- Q: The fire prevention board line is made of what material?
- (1) if it's real wood floor, the line should be made of wood. The ready-made wooden line, walnuts, price range depends on the texture width. The common width is 100 mm. One linear meter is around $17 - $30. Paulownia is cheaper with one linear meter more than 10 yuan. When it is composite wood floor, high-density plate modelling line can be used. The price is commonly between 40 to 80 yuan (2400 x 1200 mm), which depends on the thickness and density and also the factory. There are also imitated wooden aluminium line. (3) if it's the marble ground, you would better use marble line, which is 200 yuan one square meter. It's price is also unequal. The imitated stone is also available. There are a lot of kicking decoration materials and it depends on how you use it. That is to say crural line should be coordinate with the ground. It means that it sjould not only to be beautiful but also to be practical. It would be better if it is relatively cheap as well.
- Q: Why can aluminium hydroxide not be used to make refractory material?
- Hope my answer is helpful to you. It decomposes and produces aluminium oxide and water after heating, chemical equation for the reaction is: 2Al(OH)3=△=Al2O3+3H2O. Aluminium hydroxide can't be directly used to make refractory material because aluminium hydroxide is not stable.
- Q: What is the classification standard of fireproofing material levels?
- Standard: Class A: Incombustible building material, almost without burning. class A1: Non-combustible, no open flame,class A2: Non-combustible,it needs to measure smoke and be qualified. Class B1: Nonflammable building material: Nonflammable materials have good flame resistance function. when it contacts open fire or is under high temperature, it's difficult to burn and be spreading rapidly, and will stop burn after removing the combustion?source. Class B2: Combustible?building?materials: Combustible materials have good flame resistance function. when it contacts open fire or is put in the air at high temperature, it will immediately burst into flames, and easily result in the spreading of fire, such as wooden column, timber roof truss, timber beam, wooden stairs, etc. Class B3: Inflammability building materials, without any flame resisting effects, easy to burn, and has large danger of fire disaster.
- Q: What refractories are accessible with ease in daily life? This material is suitable as a disposable mold and crucible for melting brass.
- The refractory that you want is high temperature furnace which you can buy from the market.
- Q: What's the classification of flameproof glass, the refractory time of fireproofing glass.
- According to different manufacturing technique, thermal insulation fire-resistant glass can be divided into grouting fireproof glass and composite fireproofing glass. Grouting fireproof glass has good thermal insulation performance, composite fireproofing glass has good fireproof?performance.
- Q: Which one is the best refractory material?
- 1, Acid refractory usually refers to the refractory material whose content of SiO2 is more than 93% , and is characterized by erosion resistance to acid slag under high temperature , but it is easy to react with alkaline slag. Commonly used acid refractory materials include silica bricks and clay bricks. 2, Alkaline refractory material is a kind of refractory material whose components are magnesium Oxide or the mixture of magnesium oxide and calcium oxide. 3, Aluminosilicate refractory refractory material refers to refractory material which makes SiO2-Al2O3 as the main component. According to the content of Al2O3, it can be divided into semi silica (Al2O3 15~30%), clay (Al2O3 30~48%), high alumina (Al2O3 > 48%). 4, Fusion-cast refractory material refers to a kind of refractory product that melt the batch through some certain methods refractory products, and then pouring into a certain shape. 5, Neutral refractory materials mean that under high temperature, don’t react with acidic or alkaline slag. 6, Special refractory material is a new type of inorganic nonmetal material, which is developed on the basis of traditional ceramic and refractory materials. 7, The amorphous refractory material is a mixture of refractory aggregate and powder, binder or admixture, which can be used directly or after adding the appropriate liquid mixing.
- Q: What are the requirements for the performance of refractory materials?
- Refractory materials should have very high refractoriness, high temperature heat load and resistance to softening, melting; with high volume stability, resistance to high temperature and heat load, volume shrinkage and only uniform expansion; high strength at room temperature and high temperature strength, high load softening temperature, under the joint action of heat load and heavy load, no loss of strength, creep collapse; Electric furnace analysis should have good resistance to thermal shock, resistance to rapid temperature changes, no crack, not flaking; with excellent slag resistance.
- Q: Can anyone say something about what A-level fire-proof decorative material is?
- Combustion performance rates of decoration materials ratess combustion performance of decoration materials A incombustible B1 flame retardancy B2 flammability B3 high flammability The B1 rate combustion performance of gypsum plaster board and mineral wool acoustic panel absorber installed on steel joist can be used as A-level decoration materials. Inorganic decorative coating applied on the A level substrate can be used as A level decoration materials. Hope you adopt
- Q: Who knows the highest temperature the high-temperature refractory coating can resist?
- The fire endurance of high temperature fire resistant coating is 3 hours. The fire endurance of fireproof is to go on fire resistance test of any building component according to the time- temperature standard curve, which is the period of time started from being put on fire and ended when losing support function or integrity has been destroyed or losing fire insulation function, expressed in hours. I hope my answer can help you. Thank you.
- Q: What are the disadvantages of the refractory industry?
- The rapid development of continuous casting technology allows Hua Heng refractories to be improved in variety and quality. The development of refractory for continuous casting has a significant impact on the production of continuous casting and quality of continuous casting billet. Constructing and putting Baosteel into action has greatly pushed the improvement of the refractory technology. Continuous casting refractory is an important part of the continuous casting machine. In addition to the general characteristics of refractories, it is also required functions that can purify molten steel, improve the quality of steel, stabilize temperature and composition of the molten steel, control and regulate the molten steel flow. Therefore, it is known as functional refractories. Continuous casting Refractories include: (1) ladle refractory - ladle lining, permanent lining and ventilation components; (2) tundish refractories - permanent lining, coating, insulating plates, clad etc; (3 ) functional refractories - long nozzle for non-oxidizing casting, submerged nozzle, monolithic stopper, sliding gate; (4) ceramic purifier for purifying molten , slag dam, alkaline paint and horizontal separating ring and gate board for continuous casting.
