   Factory directly 87% al2o3 0-1mm calcined bauxite with competive price

 

 Calcined bauxite introduction :

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. Very difficult to melt.

 Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution. Mainly used for aluminium, refractory material. 

 

 

Calcined bauxite use   

(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.

Q:what materials can make external wall fireproofing paint have the fireproofing effect
Fire retardant coatings are generally used for fireproofing and fire retardant of steel structure buildings, large stadiums, railway stations, thermal power station, nuclear power plants, urban tunnels, large-scale industrial plants, warehouses, flammable material surface. Improve the refractory time of buildings and combustible materials.
Q:Why the corundum can be used as refractory
Because the main component of corundum is aluminum oxide!
Q:What kind of materials are needed to make refractory bricks?
The components of the raw materials of refractory bricks. There are many types of raw materials, mainly divided into six categories: Earth, stone, sand, ore, powder and others. No.1, earth: bauxite, kaolin, clay, kieselguhr. No.2 Two: stone: fluorite, kyanite, andalusite, forsterite, vermiculite, mullite, pyrophyllite, chlorite and dolomite, sillimanite and spinel, silica. No.3: sand: ceramic sand, zircon sand, quartz sand, magnesia. No.4, ore: chrome ore. No.5, powder: Metal powder, silicon powder, metal powder. No.6, others: Asphalt and graphite, phenolic resin, perlite, cenosphere, sialon corundum silicon sulfate, silicon carbide, water glass, silica sol, boron carbide, calcium aluminate cement, nitride materials, shale ceramsite, alumina, aluminum sol, zirconia.
Q:What kind of foundry ingot refractory materials are there? Please be more detailed.
This question is a little bit extensive, because there are too much foundry ingot refractory materials.
Q:What are the materials for refractory materials? What are their name?
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.
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:What are the use of fire-resistant material and admixture?
I am engaged in admixture and thus familiar. Welcome to exchange!
Q:which kind of fire bulkhead is better?
General business fire endurance of two products are 3 hours. Organic fire bulkhead's main ingredient is organic material, which can be used in anti-corrosion and fireproofing cable tray. Inorganic fire bulkhead's main ingredient is inorganic material, which mianly play a role of fireproofing. It's main ingredient is inorganic material, so it can't be used in acidproof and alkali resistant projects. Of course, the price of same amount organic fire bulkhead in general is more expensive than the inorganic fire bulkhead.
Q:What kind of refractory materials should be used for the intermediate frequency furnace to smelt manganese?
I am not quite clear. But you should take two aspects into consideration, namely, no pollution and strong durability.
Q:Does refractory belong to metallurgical auxiliary materials?
Refractory is widely used in industrial circle, such as metallurgy, chemical industry, petroleum, mechanical manufacturing, silicate and power, and its coonsumption is the maximum in metallurgy, accounting for 50% to 60% in total output. In order to improve slag-corrosion resistance of furnace lining, usually choose carbon-containing refractory. Refractory of various furnace lining are respectively: For the body, it is clay brick; as for the lower part, bosh and middle, it is SiC brick; for furnace bottom, it is carbon brick. Lattice brick is an important refractory product used in air heating furnace and regenerative chamber. Refractory is widely used in metallurgy. In order to improve slag-corrosion resistance of lining. Central line in tuyere and hearth are high-alumina brick. Refractory consumption is the maximum in metallurgy, accounting for 50% to 60% in total output. For the bosh and middle, it is SiC brick. In order to improve its thermal storage capacity: The furnace stack is clay brick. It is defined as refractory where the physical and chemical properties allows its use in high temperature environments; The lower furnace body
