1.Structure of Calcined Bauxite Description
Bauxite (aluminous soil; Bauxite) is also called the alumina or bauxite, main ingredients are alumina, hydrated alumina containing impurities, is an earthy mineral. White or gray, brown and yellow or light red by iron. From 4 to 3.9 g/cm3 density, hardness, 1 ~ 3 is not transparent, very brittle. Very difficult to melt. Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution. Mainly used for aluminium, refractory material.
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

- Q:What refractory materials are used in power plant
- And then I will introduce some application of thermal material in power plant (below) I hope I can help you. Energy saving is the trend of future industrial development efforts, grinding machine, conveyor belt, so the production of light thermal insulation materials will gain state support, drying kiln. Our factory mainly produce light thermal insulation brick. The refractory material we use most is light insulation brick, and the equipment used is sand mixer (Luohe, Henan)
- Q:Does anyone know fire-proof material of fireproof wooden door?
- Fireproof wooden door goes through the flame treatment, so it can prevent fire. Its principle: Fire-retardant treated timber has become flame retardant material itself and its fire endurance has increased. The commonly used method of fire retardant treatment for timber including: Spraying method, soaking method, boiling method, vacuum method, vacuum-pressure method.
- 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 .
- Q:Who knows how many kinds of fireproof insulation materials are there in the market?
- The so-called A-level materials in fire insulation materials, namely, the WW non-combustible insulation materials, and the WW material s are A-level. Inorganic fireproof and thermal insulation materials can be used as wall insulation materials to replace red bricks, therefore, they, as thermal and cold insulation materials, can reduce the thickness of walls, and save energy, as well as expand applicable areas indirectly, decreased structure weight. They are very good.
- Q:How to divide the fire resistant level of construction thermal insulation materials?
- How to divide the fire resistant level of construction thermal insulation materials: Combining three versions of GB8624 (1997,2006,2011) external wall thermal insulation fire?rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. There are many technical indexes for specific division, very professional and technical, so it is hard to say clear now. For details, please contact Qingdao Shanfang Instrument Company who is specialized in fire?rating tester for external wall thermal insulation materials.
- Q:what is steel fire door made of ?
- 1. fire resistance steel door has steel made door frames, door leaf framework and door panels. if the door leaf is filled with nontoxic fire insulation material, added with fireproof hardware accessories, which consists of a door that is fire resistance. 2. Category 1)safety facilities to prevent underground building from fire expansion and control volatilation. It is usually divided into steel and wooden fire door. 2) Class A fire doors, fire endurance of 1.5 hours; B fire doors, fire endurance of 1.0 hours; Class C fire doors, fire endurance of 0.5 hours. 3) In fact, there are many types of fire doors.

Ceramic fiber coating cloth and slag cloth, sintering ceramic fiber cloth and ceramic fiber fumigation cloth) Characteristics of the ceramic fiber cloth: high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment; Applications of ceramic fiber cloth: It can be applied to the thermal insulation of all kinds of furnaces, high-temperature pipelines and vessels; furnace doors, valves, flange seal, fire doors, fire resisting shutters and high-temperature furnace door curtains; engine and instrument insulation, clad material of fireproof cables, and high-temperature resistant and fire-proof materials; thermal insulation cloth for coverage, high-temperature expansion gap padding, and inner linings of the flue; high temperature resistant labor safety products, fireproof suits, high-temperature filtration and sound absorption, replacement of asbestos, etc.
- 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:Who knows what fire heat preservation material are there?
- Organic material, polystyrene board, plastic extruded board, phenolic resin. Sea capacity module (fire insulation materials fire performance can reach the B1 level, thermal conductivity is only 0.028w\m - K is a good choice, class A fireproof materials now is the mainstream rock wool (mineral wool is wool). A1 fire resistance The largest manufacturer is Thai stone rock wool Co. Ltd.
- Q:Are the rubber insulation materials are refractory materials?
- Compared with the fireproofing properties, the main thermal insulation properties of level B1 will be carbonized and drop when it is over 200 degree. <p class="answer-refer mt-10 f-light-gray" accuse="aRefer"> Reference: It is provided from technicians of Guangzhou Ou Fu construction materials: The answer that has been got:
