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.
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
(1) aluminium industry. Used in national defense, aerospace, automotive, electronics, chemical industry, daily necessities, etc.
(2) precision casting. Alumina clinker made after the mould precision casting processed into fine powder. Used in military industry, aerospace, communications, instrumentation, machinery and medical equipment department.
(3) is used for refractory products. High bauxite clinker refractoriness is as high as 1780, chemical stability strong, and good physical properties.

- 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:What kind of refractory bricks material is best?
- Domestic experimental electric furnace body is made up of hearth, insulating layer and shell. Sic and high-alumina material are often used in traditional electric furnace under 1300℃ traditional furnace, while corundum material is used in 1600℃. Laboratory furnace of Occident usually uses ceramic fiber tank which is characterized by rapid temperature raising, good accuracy, light weight and small volume. In recent years, domestic Hangzhou blue sky Instrument and Shanghai laboratory equipment all have been produced by experimental furnace with ceramic fiber tank.
- 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, other bus lines can be operated long-term at full load.
- Q:What does fire-resistant insulation coating have?
- What is the most famous is that grade A is incombustible?thermal?insulation?material. W W inorganic active wall insulation materials, cement foam insulation board, vitrified?micro bead?thermal insulation?mortar, rock wool board, glass wool board, foam ceramics, etc.
- Q:What are grades of refractory materials?
- Refractories have lots of varieties which all have different purposes.1 divided according to the level of refractoriness: ordinary refractory materials: 1580 ℃ to 1770 ℃, advanced refractories: 1770 ℃ to 2000 ℃ and super refractories: above 2000 ℃ 2, divided in accordance with shapes and sizes : Standard ones: 230mm × 113mm × 65mm, no more than four ruler.
- Q:Does anyone know the fire endurance of steel stud partition?
- Indeed ① Dragon Brand gypsum board fire-resistant partition: Its fireproofing extreme time is 4 hours, suitable for firewalls of a variety of public buildings, public exit passageway and other partitions, which meets the first level of fire protection standard ② fireproofing and pressure-resistant partition: Refers to the partition which can withstand momentary gas shocks of over 1200pa , mianly used for the room partition with inert gas fire-fighting needs, such as equipment rooms. The pressure-resistant degree of fireproofing and pressure-resistant partition of Beixin Building Materials can be up to 4800Pa, especially suitable for high-rise fireproofing.
- Q:Who knows the new fireproof and thermal inuslation matertial?
- New fireproof and thermal inuslation matertial: foam concrete building blocks brick. The foam concrete building blocks brick is a new fireproof and thermal insulation material, with distinct advantages compared with the organic insulation material . Foam concrete can be used as wall materials, and it has a good self-insulation properties, so there is no problem of dropping off the outer insulating layer. A small part takes external wall exterior insulation, with mostly anchoring or dry hanging, which are not easy to fall off. Very few uses paste. Since the foam concrete and wall materials are of the same nature and strong adhesive, so it is also not easy to fall off.
- Q:What are some of the new refractories and what are their characteristics?
- These refractory materials can be bought in Zhengzhou real gold refractory materials factory. If necessary, we can visit the factory in Xinmi first.
- Q:What dose the fireproof and thermal insulation material include?
- It includes A1: Non-combustible inorganic monomer; A2 Non-flammable organic compound, namely composite material; A3 Modified phenolic fireproof materials.
- Q:What's the organzational structure of refractory material?
- Although hacing same chemical composition refractory material products also is mineral organizer. There are differences in the type of mineral phase, high refractoriness under load, quantity and crystalline state. The organizing minerals and microstructure are reflected by folding strength, high temperature pit definite density torsional strength, high-temperature torsional strength and product property. But, for example, wear or crack may cause damage. The performance index can reflect the internal structure of refractory: the nature of the thermal performance---linear expansion coeffcient. And the mineral composition of refractory material depends on the chemical composition and process conditions, the heat capacity and temperature conductivity. If the processing conditions are different, the influence of chemical action, and thermal conductivity: represents the nature of the mechanical properties - normal temperature, high temperature compression strength, high temperature creep performance and elastic modulus. Chemical compositions are the basic characteristics of refractory, representing the nature of the density---porosity, corrosion occurred refractory materials in high temperature use As a result, the composition and quantity directly determines the performance of refractory, true density: representing the forming of high temperature performance --- refractoriness, high temperature volume stability, so you can't analyze the effect on the product performance just from chemical composition. The performance of various refractory materials are different. It must be emphasized that macroscopic organization structure of refractory material is also an important factor that affects performance; reflecting complexity of penetration---air permeability, thermal shock resistance and slag resistance. The main component is the foundation of refractory characteristics.
