     China Calcined Bauxite Ore Metallurgical Grade Bauxite for Cement Industry

 

Bauxite is a kind of earthy minerals, the main constituent is impurity hydrated alumina. It is white or

off-white, but it will appear tawny or light red because of adding iron.

Bauxite is extremely difficult to melt. It is insoluble in water, but soluble in sulfuric acid and sodium hydroxide solution.

Q:What is acid refractory material?
Many kinds of refractory materials, usually by refractoriness level is divided into ordinary refractory materials (1580 to 1770 DEG C), advanced refractories (1770 to 2000 DEG C) and special refractories (more than 2000 DEG C); according to the chemical characteristics into acid refractory material, refractory materials and basic refractory materials. In addition, there are refractories for special occasions. Acid refractory with silicon oxide as the main component, are commonly used in brick and clay brick. Silica is silica containing more than 93% silica products, raw materials used in silica, silica and other waste, the acid resistance of slag erosion ability, high load softening temperature, volume shrinkage after repeated burning, or even a slight expansion; but it is vulnerable to the erosion of basic slag, low thermal shock resistance. The brick is mainly used for thermal equipment of glass furnace, coke oven, acid furnace etc.. Clay brick with refractory clay as the main raw material, containing 30% to 46% of alumina, weak acid refractory material, heat shock resistance, resistance to acid slag, widely used. Neutral refractory is mainly composed of alumina, chromium oxide or carbon.
Q:What are the construction fire-proof materials?
1. fire retardant coating 2. fireproof panel 3. fire proof and sealing material 4. flame resisting decorative materials 5. Green fire prevention materials
Q:How many levels are there in the classification of PP fireproof materials?
The level of fireproof materials: A-level: Non-combustible building materials have rare chance to burn. A1-level: Non-combustible materials, no open fire A2-level: Non-combustible materials, smoke should be tested and qualified. B1-level: Fire-retardant building materials: Fire-retardant materials are good at resisting flame. It is difficult for them to burst into fire when coming across open fire in the air or at high temperature. It will not quickly get wilder and when the fire source removes, it will be extinguished immediately. B2-level: Combustible building materials: Combustible building materials can play a certain role in preventing combustion. It will immediately burst into flames when coming across open fire or at high temperature, and will lead to fire spreading, such as wooden pillars, roof frames and beams as well as stairs. B3-level: Inflammable building materials are highly flammable with no flame retardant ability, fire risk is high.
Q:Which manufacturers have the best fire-proof materials with light weight?
It now appears that asbestos is the best among the most common fireproof materials. But asbestos also has great harm, especially to lung. Shanghai Xinlong Fireproofing Material Co., Ltd. and Hubei Boyue Lightweight Material Co., Ltd. were established in 2009. The company is located in Wuhan Biological New Town and covers an area of ​​30 acres. The company is a specialized enterprise which is mainly engaged in the research and development, production, sale and construction of lightweight partition board, lightweight fireproof wall panel and lightweight wall panel. The two companies are both good.
Q:Do you know where I can buy refractories?
You can buy refractories in these places: 1. Addresses of refractory factory: No. 57, Qingshan District, Wuhan 2. Address of Qingshan refractory factory in Wuhan: Special NO.1 Xingli Road Hongshan District, Wuhan 3. Address of Xinghuo refractory factory in Hongshan district: No. 34 Qingshan District, Wuhan 4. Address of Henao refractory factory: No. 78 Jiangxia District, Wuhan
Q:Is there requirement for radiation indicator in refractory?
All refractories have no radiated harm to environment, so there is no requirement. From the elemental analysis, magnesite. I do not know it is helpful to you. But for refractory rwa material, any chemical element is radiated, including silicon dioxide; If they are radioactive. From the use analysis, such as bauxite, do not have use value.
Q:How can refractory materials be divided?
There are many criteria for the classification of refractories.Just referring to a book about refractory.
Q:What kind of foundry ingot refractory materials are there? Please be more detailed.
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, etc.
Q:What needs to be noted when choosing and using blast furnace fireproof materials? Who knows?
there are different temperatures in various parts of the blast furnace, thus using different types of refractory.
Q:Does anyone know which materials belong to light fire resistant material?
Building board of lightweight fireproof partition material: 1, GRC lightweight partition material glass fiber reinforced concrete; it is a kind of fiber cement composite with alkali-resistant glass fiber as reinforced material and cement mortar as the base material . Aerated concrete block equipment foundation construction Its outstanding features are having good tensile, rapture strength and good toughness. This kind of material is particularly suitable for the production of ornament mould and the manifestation of strong texture. Compared with these external wall decorative materials, the biggest advantage of GRC material is to meet the individual needs of architects, completing the expression of various ornament moulds and skin textures. 2, fiber reinforced low alkalinity cement building plate. The standards stipulate the classification, raw materials, technical requirements, test methods, inspection rules, packaging, labeling, transport and storage of the fiber reinforced low alkalinity cement building plate.
