1.Structure of Calcined Bauxite Description
Calcined Bauxite for Low Cement Ladle Linning as Refractories Materials Originates in China
Bauxite (aluminous soil; Bauxite) is also called the alumina or bauxite, main ingredients are alumina, hydrated alumina containing impurities, is an earthy mineral.

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 for Low Cement Ladle Linning as Refractories Materials Originates in China
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
Calcined Bauxite for Low Cement Ladle Linning as Refractories Materials Originates in China
(1) aluminium industry. Used in national defense, aerospace, automotive, electronics, chemical industry, daily necessities, etc.
(2) precision casting. Alumina clinker made after the mould precision casting processed into fine powder. Used in military industry, aerospace, communications, instrumentation, machinery and medical equipment department.
(3) is used for refractory products. High bauxite clinker refractoriness is as high as 1780, chemical stability strong, and good physical properties.
(4) aluminum silicate refractory fiber. With light weight, high temperature resistance, good thermal stability, low thermal conductivity, heat capacity is small and the advantages of resistance to mechanical shock. Used in iron and steel, nonferrous metallurgy, electronics, petroleum, chemical, aerospace, atomic energy, defense and other industries.
(5) in magnesia and bauxite clinker as raw materials, add the appropriate binder, used for pouring ladle whole ladle lining has particularly good effects.
(6) manufacture alumina cement, abrasive materials, ceramic industry and chemical industry can be aluminum of various compound.

- Q: What is the difference in the nature between the refractory material and thermal?insulation?material
- thermal?insulation?material is a material which has a strong impedance to the heat flow. the nature of the material requires that the material can isolate the delivery of thermal, and the low heat conductivity coefficient and expansion coefficient of the non-metal material.refractory is good in heat resisitance and chamical erosion but not high temperature resistance. Requirements on nature is still in high temperature.
- Q: What's the refractory material?
- Frequently used refractory material: AZS brick, corundum brick, direct-bonded?magnesia-chrome?bricks, carborundum brick, silicon nitride bonded silicon carbide brick, nonoxide refractories like nitride, silicide, sulfide, boride and carbide, and oxide refractories like calcium oxide, chromium hemitrioxide, alumina, magnesium oxide and beryllia. In general, the refractory material include the above. For more information, you can ask for specific advice.
- Q: What's the function of aluminium dihydrogen phosphate on the refractories?
- Mainly used for binder of high-temperature furnace refractory. Characteristics of liquid aluminum dihydrogen phosphate, castable. solid used for refractory spraying coating, chamotte, ceramic construction, which has high break resistance after being dried in 350-500 ° C, phosphate bricks. Characteristics of the solid aluminum dihydrogen phosphate, binding agent used for castable and casting industry: together with the refractory aggregate, ramming mixes at room temperature: Easy to mix, crush resistance, hydration resistance, chamotte, will not become soft even if soaked or boiling in water, molding. Liquid use refractory spraying coating, mainly used for corundum, chrome corundum water gap in refractory industry. The production of chrome aluminum zirconium corundum brick for water-coal-slurry gasifier is especially suitable for site construction applications mainly used for the electrical industry, high-temperature kiln and furnace, hardener, after mixing between 90-110 ° C for 4-24 hours at a constant temperature, forming strong bonding strength, electrical insulation, heat treatment resistance furnace
- Q: Refractory factory grinding brick dust harmful to the body?

- Antioxidant: Si, Al, Mg, Ti, AlSi, AlMg, SiC, TiC, ZrC and these metal nitride, boride. Sintering agent: different mechanism, Cr2O3 to promote the sintering of alumina;CaO/MgO style promote ZrO sintering;Siliceous ramming material to add boron bottles, magnesia coating and clay, etc.
- Q: What is the material composition of the new fire-resistant coating?
- New fire-resistant coating generally consists of base material, dispersion media, flame retardants, fillers, additives (plasticizers, stabilizers, waterproofing agents, moisture, etc.). (1) Base material is the basis of the composition of the coating, and it is the main film-forming substance, playing a decisive role in coating performance . For fire-resistant coating, its base material must be capable of matching with the flame retardant to constitute an organic fireproofing system. The base material commonly employed at home and abroad includes inorganic and organic film-forming material. Inorganic film-forming materials include silicate. Si03, K2 Si03Na2 Si03), silica and phosphate [Al. (HPO.). ] ect. There are a wide range of organic film-forming substance, usually flame retardent organic synthetic resins, such as phenolic resins, halogenated alkyd resins, polyester, halogenated olefin resins (such as vinyl chloride resin), amino resin (melamine resin, urea resin, etc. ), tar-based resins, furan resins, heterocyclic resins (e.g., polyamide-imide, polyimide, etc.), organic elements resins (e.g. silicone resin), rubber (halogenated rubber such as chlorinated natural rubber) and so on.

- Q: What material is used to make furnace pipe of refractory bricks?
- Refractory brick is called refractory?brick for short. It is a kind of refractory material fired by using refractory clay or other refractory materials. Faint yellow or brownish. It is mainly used in building smelting furnace and has resistance to high temperature 1,580 ℃ -1,770 ℃. Also known as refractory?brick. It is refractory material with a certain shape and size. It can be divided into burnt brick, unburned?brick, fused brick (fused cast brick), fire-resistant insulation brick according to preparation technics; It can be divided into standard brick, ordinary brick and special-shaped brick, etc according to shape and size. It can be used as high-temperature building material and structural material of building kiln and all kinds of thermal equipment. It can also withstand a variety of physical and chemical changes and mechanical action under high temperatures. For example, fireclay brick, high alumina brick, silica?brick, magnesia brick, etc.
- Q: What is the acceptance standard of refractory?
- Feeler gauge is used to check the thickness of the refractory brickwork joint. The top of the gauge can not be sharpened. Feeler gauge is of the width of 15mm, length of 100mm and thickness of 1, 1.5, 2 or 3mm. The thickness is eligible when the depth which the feeler gauge is inserted in is less than or equal to 20mm. Ten places should be inspected per 5m2 of masonry surfaces. It is qualified when the condition in which thickness of the brickwork joint is 50% larger than a predetermined depth is not less than five times and it is excellent when the condition is no more than two times.
- Q: What refractories can withstand high temperature above 2100 degrees?
- But the price is more expensive, while the insulation performance is not as good as common materials. Is there a material that can withstand 2100 ℃? Currently, the long-term use temperature of the best refractory bricks is about at 1800 ℃, while materilas that can withstand a temperature of 2100 ℃ are relatively rare in the production.
- 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.
