Product Introduction

Refractory Material Bauxite Clinker for All Kinds of Particle Size

Bauxite, also known as alumina, the main component is alumina, which is hydrated alumina containing impurities, a kind of earthy mineral. White or gray, because containing iron it will brown yellow or light red. Density is 3.45g / cm3, hardness is 1-3, opaque, brittle. Extremely difficult to melt. Insoluble in water, soluble in sulfuric acid and sodium hydroxide solution. Mainly used for aluminum smelting, manufacture refractories.

Product Application

Refractory Material Bauxite

1. aluminum industry. For defense, aerospace, automotive, electrical, chemical, and other daily necessities.

2. casting. Bauxite is processed into a fine powder made after the mold casting. Used in military, aerospace, communications, instrumentation, machinery and medical equipment sectors.

3. used for refractory products. High bauxite refractoriness up to 1780 ℃, chemical stability, good physical properties.

4. aluminosilicate refractory fibers. Light weight, high temperature, good thermal stability, low thermal conductivity, heat capacity of small and resistance to mechanical vibration and so on. For iron and steel, nonferrous metallurgy, electronics, petroleum, chemical, aerospace, nuclear, defense and other industries. It is the high alumina clinker into the melting temperature of about 2000 ~ 2200 ℃ high temperature electric arc furnace, high temperature melting, high pressure high velocity air or steam injection, cooling, it becomes white "cotton" - aluminum silicate refractory fibers. It can be pressed into fiber blanket, plates, or woven into fabric instead of smelting, chemical, glass and other industrial high-temperature furnace lining of refractory bricks. Firefighters available refractory fiber cloth to make clothes.

5. with magnesia and bauxite as raw material, adding an appropriate binder for casting ladle whole bucket liner very good results.

6. manufacture of cement, abrasive materials, ceramic industry as well as various compounds chemical industry can be made of aluminum bauxite.

Bauxite Ore / Raw Bauxite / High Alumina Bauxite

Q:What's the refractory material in common use currently?: (1) Alumina-silica refractory brick: Except the transition band, hot end and firing zone of the rotatory cement kiln, it can be applied to the whole burning system of the precalcining kiln, such as the fixed wall lining, wicket, cooling machine, tertiary air duct, burner, etc. It mainly includes alkali-resisting brick, high alumina (anti stripping) brick, silica-mullite brick, etc. (2) Basic refractory: For the upper transition band close to the part of burning zone and the burning zone, its inner lining can endure the highest flame temperature of 2000℃ and material temperature of 1350℃-1400℃, and it also has to withstand the permeation of sulfur and alkali compounds, permeation, thermal shock and oxidoreduction of hot-melt clinkers (liquid phase), mechanical stress of elliptic cylinder deformation, etc. Therefore, inner linings are the most demanding parts to withstand stress, and only basic refractory can meet with requirements under this working condition. (3) Fireclay insulating refractory: Its microstructure has notable characteristics of high porosity, large pore size and thermal insulation performance. For its low volume density and light weight, it is usually referred to as lightweight refractory. Fireclay insulating refractory product has great varieties, and it is usually classified and named according to its chemical and mineral compositions or production raw materials, and it is also classified according to its operating temperature and material form. Currently, the most used main thermal insulation material for the precalciner kiln system at home and abroad is calcium silicate board; besides, light weight castable and insulating fire brick are increasingly used year by year. Other thermal insulation materials are mainly ceramic fiber products.

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:What kind of materials are needed to make refractory bricks?: Refractory materials generally refer to inorganic non-metallic materials with fire resistance above 1580℃. It plays an important role in metallurgy, nonferrous metals, chemical engineering, ceramics, and industrial production. Different industry needs different materials. You can turn to the knowledgeable internet.

Q:What is the function of refractory in ceramics?: Refractory is used as materials of kiln,sagger and kiln car for ceramic sintering. Its refractoriness is higher than ceramics, and the essential material and tool for ceramic sintering.

Q:Which are fireproofing external wall materials?: According to combustion performance, external wall thermal insulation materials are classified as Grade-A and Grade-B. Grade-A refers to incombustible material and Grade-B combustible material. A few years ago the fire in CCTV building and Shenyang Hotel were caused by Grade-B material. Currently Grade-A material is more commonly uesd and less expensive than Grade-B material. Grade-A material can be divided into thermal mortar, phenolic foam board, rock wool board, foam cement board, etc. Thermal mortar is easy for construction and unexpensive, but it is also easy for faking due tou its simple procesing. It is recommended to find a large factory whihc has gone through the formalities.

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 type of fire proofing thermal insulation materials?: Aluminum silicate: AlSiO3 With flint clay clinker as raw material, aluminum silicate is made by resistance or electric-arc furnace fusion and then spraying processing. Aluminum silicate fiber, also known as ceramic fiber, is a new lightweight refractory material featured by light weight, high temperature resistance, good thermal stability, low heat conduction rate, small heat capacity, good mechanical vibration resistance, small thermal expansion and good thermal insulation. It can be processed into aluminum silicate fiber board, aluminium silicate fiber felt, aluminium silicate fiber rope, aluminium silicate fiber blanket, etc. Featured by high temperature resistance, low heat conductivity coefficient, light weight, long life, good tensile strength and elasticity and no toxin, this new sealing material is an alternative of asbestos and widely used for thermal insulation of thermal energy equipment in metallurgy, electric power, machinery, chemical industry, etc.

Q:What is molten silicon? What refractoriness do refractories made by it have? What properties of using does it have?: Molten silicon can be called quartz glass, which shows an amorphous silicon state. It is a liquid fusion at above 1723 degree and is an ultra-cooling state at low temperatures. It is not generated in refractories, but generated in the matrix, showing liquid state at a high temperature capable of buffering the stress with somewhat binding properties. If quartz glass is used as refractory, its function are melrly these ones. (These are what I konw for reference only.)

Q:What kinds of fireproof and fire retardant materials are there?: general classification of fire retardant materials will use A, B in the home improvement supplies. A has the best flame resistance, followed by B.

Q:How is the development of Xinmi refractories industry? What's its advantages and disadvantages?: I don't know how it has developed. Its advantage is the coal industry. You have to know the generating capacity in Xinmi thermal power plant first, and then you will know their coal cinder yield, after all, this is the raw material. Xinmi is not far away from Zhengzhou. The real estate in Zhengzhou is still good. I'm not sure about the others.
