Product Description:

bauxite for sale/bauxite buyer/sell bauxite ore

 

Discription:

 

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 thereby 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.

Q:Can anyone tell me what is the material of which the mould for refractory is made?
Wooden mould will be used when refractories die is produced in small batch or composition of the refractory is complex. At the time of mass production, steel mould wil be used. The steel mould is a kind of imprint mold or cold mould. The cold mould, according to the working conditions of the products it manufactures, should have high hardness, strength, wear resistance, sufficient toughness and high hardenability. Commonly used steel types include high-carbon and low-alloy steel, high-carbon and high-chrome steel, chromium molybdenum steel and tungsten carbon chromium steel. You can choose them based on your needs
Q:What are the applications of refractory busway?
Refractory busway is designed for the power supply in fire-fighting equipment, and it can not be used for other purposes. As the generatrix has good heat resistance, thermal insulation, and the heat of the busway can not be emitted, it can not be used long-term at full capacity. In addition to fire-resistant busway, ther bus lines can operate full-load in long term.
Q:What is the main constituent of refractory brick?
The main constituent of silica brick is monox, etc. Refractory bricks have many kinds of texture. The main constituent of high alumina brick and clay brick is aluminium oxide. The main constituent of every texture is different. The main constituent of magnesia bricks and magnesia-chrome bricks is magnesium oxide.
Q:Who knows about the B-level fireproof insulation materials?
Organics, extruded sheet, polyphenyl board and phenolic resin. The fireproof performance of sea capacity module (fireproof and thermal insulation material) is B1-level with the heat conductivity coefficient of only 0.028w / m · k. It is a good choice. A-level: Rock wool, glass wool, silicate, aluminum silicate, calcium silicate, phenolic aldehyde, and foam glass. B-level: Rubber and plastic, extrusion molding, polyphenyl, PEF.
Q:Does anyone know about the fire resistance period of thin fireproof coatings?
Outdoor thin steelwork fireproof coatings have a fire resistance of 2.0 hours, the thickness of coatings is between 4.5 to 5 mm, the standard amount is 5.5 to 6kg per square meter. Specific situations vary according to the thickness data provided by manufacturers . The fireproof coatings are applicable for the surface of combustible substrates, which can reduce the flammability of the surface being painted, and block the rapid spread of fire. They can be used to improve the fire resistance of the materials being painted. The fireproof coatings are coated on the substrate surfaces. They are also rustproof, waterproof, wearproof, heatproof and anticorrosive apart from flame retardant. They have good tenacity, stainability, adhesiveness, glossiness and fast-drying nature.
Q:Which manufacturers have the best fire-proof materials with light weight?
Tinajin SPstar Insulation Material Co.,Ltd. is Chinese agent of German Berkson which is engaged in the application of field of high temperature and thermal insulation for many years and has accumulated experience of application of WDS nanometer scale micropore thermal insulation matrial in a variety of industries. Welcome domestic customers and experts in all industries to contact us and cooperate to promote this new energy-saving insulation materials. Make due contributions for China's energy-saving and sustainable development and low carbon emissions project!
Q:What is the the best ratio of mortar in refractory cement?
The ratio of refractory cement are: M10 the ratio of cement and mortar: cement: Sand= 346kg: 1631kg M7.5 ratio of cement and mortar: cement: Sand =274kg: 1631kg M5 The mix proportion of cement and mortar: cement: Sand = 209kg: 1631kg M10 mix proportion of composite mortar: cement: Sand: Lime =306kg: 1600kg: 29kg M7.5 mix proportion of composite mortar: cement: Sand: Lime =216kg: 1600kg: 64kg M5 The mix proportion of composite mortar: cement: Sand: Lime =205kg: 1600kg: 100kg
Q:How to determine the fire resistance rating of the aluminium-plastic panel?
Class A incombustible and thermal insulation material: inorganic active wall thermal insulation material, cement foam insulation board, glass bead thermal mortar, rock wool board, glass wool board, foam ceramics, etc. With many characteristics of low density, low thermal conductivity, high pressure bearing capacity, convenience of construction, economy and durability, A class incombustible material is widely used as thermal insulation material for heat pipelines, thermal equipment, other industrial pipe-line equipment and industrial buildings, and thermal insualtion and sound absorption material for the building envelop of industrial and civil buildings. Because of good thermal stability, it is more often used as fire-proof and protective coating material of the steel structure.
Q:How many types of fire-resistant material?
1. Acid fire-resistant material refers to one with more than 93% SiO2. It is featured by resistance to the corrosion of acidic slag ad high temperature and easy to react with alkaline molten slag. 2. Alkaline refractory material generally refers to one with magnesium oxide or magnesium oxide and calcium oxide as the main component. It has high refractoriness and strong resistance to basic slag. 3. Silicate aluminum refractory material refers to one with SiO2, Al2O3 as the main component. According to the content of Al2O, it can be divided into three categories: half siliceous (15-30% Al2O3), clay (Al2O3 30 ~ 48%), high aluminum (more than 48% of Al2O3). 4. Fused cast refractory material refers to shaped refractory products made by high temperature melting and casting.
Q:Who knows how to divide the building fire grade and fire resistance grade?
I hope to help you building fireproof rank division is one of the most basic measure in building fire safety technical measures, Building's fireproof rank is divided into class one, two, three, four according to China's architectural design specification. Fire-resistant capability of the highest level is the strongest; Fire resistance of four level of the weakest. The fire resistance level of a building depends on the combustion performance and fire resistance of the building components that comprise the building. The so-called building component refers to a series of basic components, such as wall, foundation, beam, column, floor, stair, ceiling and so on. The judgment condition of the fire resistance There are three conditions for components' fire resistance limit to be reached, namely, the fire resistance limit of the building component: Loss of support and integrity; loss of time to fire the role of the time; as long as any of these three conditions is met, it will reach its limit of fire. Hope my answer will help you.
