Factory Directly 85% Al2O3 1-3mm Calcined Bauxite with Low Price

 

1.Calcined Bauxite Description

A general term for a rock composed of hydrated aluminum oxides. It is the main ore of alumina to make aluminum.  Also used in the production of synthetic corundum and aluminous refractories. The bauxite is purified by the  Bayer Process. First the ore is mixed with a hot concentrated solution of sodium hydroxide. The NaOH will dissolve  the oxides of aluminum and silicon but not other impurities such as iron oxides, which remains insoluble. The  insoluble materials are removed by filtration.

 

2.Main Features of the Calcined Bauxite

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 is typically calssified according to its intended commercial application,such as abrasive ,cement , chemical l, metallurgical, and refractory .as raw material for use in high alumina and super duty refratory bricks  and shapes ,plastics ,castable refratory, motors, gun mixes, ramming mixes, abrasive grains and other products chemical composition .

Q:The classification of clay according to refractoriness, and what is the plasticity and plasticity index of clay?
Q:What is glass furnace used high-grade refractory materials?
It is said that building a furnace need 30 million? After the ignition, it can't be gone out. Only at the waste to maintenance?
Q:As for fireproofing material rock wool and glass wool, which one is better?
As for fireproofing effect, the effect of rock wool is certainly better than glass wool , the highest temperature of rock wool is 1100 ℃, but the temperature of glass wool is only 600 ℃. In addition, if it's used in the external walls, then,unit weight of the glass wool is limited,and high unit weight can only be 60-90, but unit weight of rock wool can reach over 140, now external wall can't use glass wool, and only rock wool is A class fireproofing material. glass wool has lower thermal conductivity, rock wool has longer fiber length,as for the price, tons price of glass wool is more expensive than rock wool, but if it's acculated by square, square price of glass wool is cheaper than rock wool.
Q:What are the best refractory materials in 2,400 Celsius degree?
You can try zircon sand which has a melting point of 2430.
Q:What's the classification of refractory material?
Magnesium aluminum is complex and mainly seeing what classification standard is like according to the appearance shape can be divided into two categories, setting and not setting according to the acid alkali can be divided into acidic, magnesia, high aluminum, ramming expected, spinel, spray coating, plastic, just the quality of the jade, daub material according to the chemical composition is divided into, such as clay, neutral and alkaline according to the operation mode can be divided into different castable, magnesium, calcium, magnesium chrome
Q:What are the refractory materials above 1000℃
I have no idea what field you are in, and I am skillful at making refractory materials, because this is my job. You can send me an email informing your purpose, here is my email address sihouzm@yeah.net.
Q:How is the grading of the level A new material fire insulation material?
The thermal insulation materials are generally divided into level A and level B according to the flame rating. Level A is the non-combustible material, and level B is the combustible materials. The level B material is to blame for the fire in Shenyang hotel in CCTV building a few years ago . At present, the level A materials are widely used, with some prices even cheaper than the level B material. A level is roughly divided into insulation mortar, phenolic board, rock wool board and foam cement board, ect.
Q:The difference between refractory and thermal insulation material
In simple terms, refractoriness is different. The refractoriness of refractory is high while that of insulation material is low.
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:How do refractory materials apply into pyrophyllite?
Generally speaking, shaped refractory materials require of some powdery materials like spray grouts and iron trough in addition to pyrophyllite brick made of a mixture of pyrophyllite aggregate and powers.
