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.

- Q: What are the materials of insulation firebricks?
- The raw materials of firebricks, firebricks have various raw materials, and the composition of which can be divided into six categories: soil, stone, sand, mineral, powder and others. One of the raw materials, soil: bauxite, kaoline, clay, diatomite Another raw material, stone: fluorite, kyanite, andalusite, forsterite, vermiculite, mullite, pyrophyllite, chlorite, dolomite, sillimanite, magnesia-alumina spinel, and silica Another raw material, sand: clay sand, zircon sand, quartz sand, and magnesite Another raw materials, mineral: chromium mineral Another raw material, powder: aluminum powder, micro-silica powder, and silicon powder Another raw materials, others: asphalt, graphite, phenolic resin, perlite, cenosphere, sialon, corundum, silicon sulfate, silicon carbide, sodium silicate, silica sol, boron carbide, calcium aluminate cement, nitride material, haydite, aluminum oxide, alumina sol and zirconia, etc.
- Q: Does anyone know the difference between refractory and thermal insulation material?
- The main difference between insulation bricks and refractory bricks are as follows: 1. Insulation effect The heat conductivity cofficient of insulation bricks is usually 0.2-0.4 (average temperature of 350 ± 25 ℃) w / mk while the heat conductivity coefficient of refractory bricks is 1.0 (average temperature of 350 ± 25 ℃) w / mk or more. Thus it can be seen that the insulation effect of insulation bricks is much better than that of refractory bricks. 2. Refractoriness The refractoriness of insulation bricks is generally below 1,400 degrees centigrade while the refractoriness of refractory bricks is above 1,400 degrees centigrade. 3. Density Insulation bricks are generally light-weight insulation material, and the density is generally 0.8-1.0g / cm3. But the density of refractory bricks is above 2.0g / cm3.
- Q: Physical and chemical indicators of various refractory.
- please read"Refractories Standard Series" for refernece, general business standards are higher than the national standard.
- Q: what's the classification of fireproof and thermal inuslation matertial?
- Inorganic thermal insulation material can do it, such as glass wool,rock wool,foam glass,etc. phenolic foam materials in organic foam material is special. phenolic foam not only has good thermal insulation properties but also can be composited with steel plate and other materials, A class thermal insulation materials that reach A class combustion performance include: rock (mine) wool, foam glass, EVB, etc. thermal insulation materials with A class combustion performance mainly include: phenolic aldehyde,gelatine powder polyphenyl granule, etc. thermal insulation material of fire barrier zone can use rock (mine) wool, foam glass, EVB and other materials with A class combustion performance.
- Q: What things and cement mixed can act as refractory?
- Cement building, portland cement, refractory grade, calcium aluminate. Cement acts as refractory need to use calcium aluminate cement.
- Q: What are the technical requirements for refractories?
- To put it simply, physical indicators are pores, volume density, pressure resistance, slag resistance, thermal shock resistance, foot expansion coefficient, thermal conductivity, oxidation resistance and so on. If it is castable, the indicators are mobility, water rate, setting time, and anti bending strength. If it is coating mix, the bonding strength should be checked. Chemical indicators are loss of ignition and the content of aluminum, magnesium, silicon, calcium, chromium, titanium and carbon.
- 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.
- Q: what is the material of fixed first rate fire resistant window?
- Fixed first rate fire resistant window is produced by the steel sash windows, steel casement, fireproofing glass. Fireproof windows, is composed by steel window frame, steel casement, fire-proofing glass. it refers to the window which can isolate and stop the fire spreading. The fire window product is named after the main material of window frame and the window casement, window frames is made of steel, casement is made of wood or the sash frame is made of wood and the casement is made of fire window.
- Q: What is the limit of fireproof rolling shutter?
- Fireproof rolling shutter door is a kind of fire protection and heat insulation facility which is suitable for the large openings of buildings, having a certain effect on the design and installation. Fire shutter doors are widely used in fire partition of industrial and civil building. It can effectively prevent the spread of fire, to protect the safety of life and property. It is an indispensable modern building fire facilities. According to the national standard 14102-2005 GB standard, the provisions of 14102-2005 GB specify that: If fire resistance limit of fire resisting shutter is no less than 3 hours, it is AAA fireproof rolling shutter. Therefore, the fire resistance limit of AAA grade fireproof rolling shutter should be 3 hours.
