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.

Applications

calcined bauxite is typically calssified according to its intended commercial application,such as abrasive ,cement ,chemical, 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.

Q:What's the requirements of fire-fighting criteria of heat insulating material?: Specific provisions go as the following article 8: roof grassroots adopted duration of fire resistance is the non-combustible component that shouldn't less than 1.00 h's. Its roof insulation materials should not be below B2; Otherwise, the combustion performance of insulating material should not be below the B1 level. Article 9: The junction of the roof and wall, the insulation layer around the opening part of roof should use the grade A thermal insulation material to set level fire-fighting belt that width is not less than 500 mm. Article 10: the roof waterproof membrane or flammable insulation layer should adopt incombustible material to cover.

Q:What are some of the new refractories and what are their characteristics?: Alumina, a better refractory material, is a new type of ceramic refractory, the characteristics are unclear.

Q:What is refractory?: Refractory materials are widely used in metallurgy, machinery manufacturing, chemical industry, petroleum, power and other industrial fields. It is an inorganic nonmetallic material mostly used in metallurgical industry with the minimum refractoriness of 1580 ℃, able to resist high temperature without softening (annealing). It accounts for 50% to 60% in total output. Refractoriness refers to refractory's ability to resist fire.

Q:What refractories are accessible with ease in daily life? This material is suitable as a disposable mold and crucible for melting brass.: There are many refractories in daily life. Such as the lining of furnace! And refractory cotton ... If you want to melt brass, you need to resort to professionals! It's rare in daily life to find out those molds that can be made by ourselves. You can buy a corundum crucible in the neighbouring laboratory equipment market! Remember that brasses' melting point is at above1000 degrees, so the material must have refractoriess of 1000 degrees.

Q:What is the function of refractory material?: Refractory is a basic material in the field of high temperature technology. Generally, the refractory is used as structural material or lining to resist high temperature in various thermal equipment and high temperature container. In the iron and steel industry and metallurgy industry, coke ovens are mainly composed of refractory materials. Various refractories that meet the requirements are essential in blast furnace for ironmaking, hot stove, all kinds of steel-making furnaces, soaking furnace and heating furnace. Not only the die casting for molten steel needs lots of refractory materials, but also the continuous casting needs some high-quality refractory materials. Without high-quality refractory materials, external refining is also not impossible to achieve. Statistics show that the steel industry is the sector that needs the most refractory. Pyrometallurgy and thermal processing of ferrous metal also needs refractories. All high-temperature furnaces or lining in construction materials industry or other high temperature industries that produce silicate products such as glass industry, cement industry, and ceramics industry must be constructed with refractory materials. All kinds of roasting funaces, sintering funaces, heating furnaces, boilers, flues, chimneys and protective layers in chemical, power and machinery manufacturing industry need refractories. In short, when some kind of structures, devices, equipments or vessels are used under high temperature, they all should utilize refractory to resist the high temperature because those materials will deform, soften and fuse or will be eroded, scoured or broken due to the physical, chemical, mechanical effects, which may stop the operation, affect the production, contaminate processed objects and impact the quality of products.

Q:For refractory knowledge. What is the ratio of clay ramming?mass?: Soil aggregates, dispersing agent, water reducing agent, plasticizer, binding agent and powder! ~ Bone meal feed approximately 6, OK

Q:Ask some questions about refractories: Is a kind of refractory material, jargon called hook materialThe iron runner: a combination of the super high Los resistant technology, aluminum and corundum, silicon carbide and other raw materials, to high-quality composite binders and additives, strict proportioning, elaborate. The utility model has the advantages of good slag resistance, good thermal shock resistance, long service life, convenient use, simple construction, and obvious reduction of labor intensity of workers.Application: it is suitable for blast furnace tapping system.

Q:What are the requirements on fire resistance period of C-level fireproof glass?: What are the requirements on fire resistance period of Class C fireproof glass? The fireproof glass is a special glass which can maintain its integrity and insulation in required fire resistance tests, it can be classified into three types: Class A the fireproof glass which meet demands of fire integrity, and fire insulation at the same time. This glass has advantages of excellent transmittance, fire-proofing(smoke resistance, fire insulation, and blocking heat radiation), sound insulation and impact resistance. It can be applied to architectural ornaments, fire resistant timber doorsets with steel structure, windows, upper beam, partition walls, daylighting roofs, ceiling screens, perspective floor and other building components which need transparency and fireproofing. Class B: The fireproof glass which meets demands of fire integrity and thermal radiation intensity at the same time. This glass is mostly composite fireproof glass which has advantages of transmittance, fireproofing, and smoke resistance. Class C: The fireproof glass which only meets demand of fire integrity. This glass has advantages of transmittance, fireproofing, smoke resistance and high intensity. It can be applied to fireproof glass partition walls, fire windows and with no requirements on outdoor curtain walls, etc. The fireproof glass can be classified as composite fireproof glass and single chip fire-proof glass in terms of structure.

Q:who knows the uses of refratories?: Of course, the role of the refractory material is fireproof, generally used in large buildings. It can reduce casualties and economic losses caused by the fire. it also can be used on the chemical instruments. ! !

Q:What is the difference between wear-resistant material and refractory material?: There must be difference. The requirements of refractory material are that it can be called refractory material when temperatures it can withstand are over 1570 ℃. Refractory material must have high strength. The specific value of refractory material is not clear.
