Product Description of 82% Rotary/ Shaft/ Round Kiln Alumina Calcined Bauxite Refractory Raw Material:

Bauxite, alumina or bauxite miner , main ingredients are aluminum oxide, hydrate alumina containing impurities,

is an earthy mineral.White or grey, brown yellow or light red by iron.From 4 to 3.9 g/cm3 density, hardness, 1 ~ 3, opaque, very brittle.

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

 

Application of 82% Rotary/ Shaft/ Round Kiln Alumina Calcined Bauxite Refractory Raw Material:

1.Aluminium metallurgy.

2.Precision casting/Investment casting: bauxite grog fines can be made into mold for precision casting.

3.Refractory: high alumina bauxite's refractoriness can reach 1780°C.

 It is charactered by good chemical stability and mechanical performance.(Al2O3 ≥48% with low Fe2O3)

4.Aluminium silicate refractory fiber: The high alumina bauxite grog can melt under2000°C-2200°C in the electric arc furnace.     After a series of processing, it can become aluminium silicate refractory fiber, which can be made into fiber blanket,plate,cloth.

5.Mixing magnesia and bauxite grog with binders to pour the molten steel ladle for better overall lining performance.

6.Producing bauxite cement.

7.Abrasives.

8.Ceramics industry.

9.Chemistry industry for all kinds of aluminium compound.

Q:What are the electrical fire protection materials?
Inorganic binder: Water glass, gypsum, phosphate, cement, etc.; Refractory mineral filler: Alumina powder, calcium carbonate, asbestos, perlite, cornstarch; the main purpose of electrical fire prevention board is to prevent fire and heat. The heat conductive plate will conduct electricity, leading to good equipment insulation and large superheating surface! ! ! ! Hope my answer will help you.
Q:Where is refractory used? Thank you!
According to its refractoriness, it can be divided into ordinary refractory (1,580℃ to 1,770℃), high class refractory (1,770℃ to 2,000) and super refractory (above 2,000℃); according to chemical property, it can be divided into acid , neutral and alkali refractories, and including refractory used for special occasion. The current definition of refractory do not only depend on whether the refractoriness is above 1,580℃. At present, refractory is widely used as inorganic nonmetallic material of production equipment lining in metallurgy, petrifaction, cement, ceramics, power, etc. Refractory generally has good thermal shock resistance, chemical attack resistance, low thermal conductivity and coefficient of expansion, widely used in chemical, construction material, mechanical manufacturing, and ceramics, accounting for 50% to 60% in the total output. It can resist high-temperature action. Refractory has many varieties. Refractory materials are widely used in metallurgy; chemical properties divided by acidic refractories. In addition, cement, silicates. Refractoriness refers to that when cones sample made from refractory has no load. Currently, refractory refers to that is widely used in metallurgy, including neutral refractory and basic refractory.
Q:Who know about the knowledge of acid refractory material? Please explain in detail.
Refers to the silicon dioxide
Q:What are the models of refractory cables?
There are bout four types. 1.NA-YJV / NB-YJV Crosslinked polyethylene insulated PVC sheath A (B) class fire-resistant power cable 2.NA-YJV22 / NB-YJV22 Crosslinked polyethylene insulated steel belt braiding PVC sheath A (B) class fire-resistant power cable 3.WDNA-YJY / WDNB-YJY Crosslinked polyethylene insulated polyolefin sheath A (B) class low smoke no halogen fire retardant power cable 4.WDNA-YJY23 / WDNB-YJY23 Crosslinked polyethylene insulated steel belt braiding polyolefin sheath A (B) class low smoke no halogen fire retardant power cable
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 is the offer of fire proofing thermal insulation material?
The following prices are from the Internet and for your reference only. Hainan fire proofing thermal insulation material ceramic fiber paper aluminum silicate fiber blanket/aluminum oxide fiber insulation cotton insulation pipe 12 yuan Hainan multicrystal mullite/calcium silicate corundum ceramic fiber loose wool short fiber fire proofing thermal insulation material non-asbestos high temperature resistant aluminum silicate fiber insulation cotton fire-resistant material ceramic fiber blanket thermal insulation blanket 28 yuan non-asbestos high temperature resistant aluminum silicate fiber ceramic fiber blanket needled felts insulation blanket fire resistant material thermal insulation cotton blanket reference price: 59 yuan
Q:who knows how to classify the fire resistant levels of fireproofing material?
Grade of fireproofing material: 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's the fire endurance of fireproof panel?
fire endurance of fireproof panel can reach 3 hours. For example, 12 mm non-asbestos fiber reinforced calcium silicate board, fireproof panel, two single 75 keel. through the monitoring of national fireproof construction materials quality supervision center, it's security and refractory time will reach over 3 hours. fireproof panel, also called fire resistance board, scientific name is thermosetting resin impregnated paper laminated wood,english abbreviation HPL(Decorative High - pressure Laminate) is fire resistant building material for surface decoration and has rich surface colors,lines and special logistics performance, it's widely used in interior decoration, furniture, cabinets, laboratory table, external wall, etc.
Q:What's the maximum temperature that the refractory ceramic fiber cloth can endure?
While the refractory ceramic fiber cloth is different in high temperature resistance, and in general it can endure the high temperature of more than 1000℃. Ceramics in daily use and art ceramics: Bone china and Guangdong chinaware can generally endure the highest temperature of 1100℃. Jingdezhen porcelain and ceramics: They can generally endure the highest temperature of 1280℃-1340℃, and some special ones can endure the highest temperature of 1400℃. Industrial ceramics: Some of them can endure the highest temperature of about 2600℃. (alumina ceramics: their melting point is 2050℃, and boiling point is 3000℃).
Q:What are the requirements for the performance of refractory materials?
Electric furnace bottom and furnace slope and the wield pool should be magnesia whole knotting, magnesia carbon brick and tar magnesia brick; hot and slag line area, using high-quality magnesia-carbon brick; Brick on both sides of the furnance door should be tapping El magnesia brick, magnesite chrome brick; electric furnace cover should be high alumina brick and high alumina bricks.
