1.Structure of Calcined Bauxite Description of CNBM in China
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 of CNBM in China
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 of CNBM in China
(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.
(4) aluminum silicate refractory fiber. With light weight, high temperature resistance, good thermal stability, low thermal conductivity, heat capacity is small and the advantages of resistance to mechanical shock. Used in iron and steel, nonferrous metallurgy, electronics, petroleum, chemical, aerospace, atomic energy, defense and other industries.
(5) in magnesia and bauxite clinker as raw materials, add the appropriate binder, used for pouring ladle whole ladle lining has particularly good effects.
(6) manufacture alumina cement, abrasive materials, ceramic industry and chemical industry can be aluminum of various compound.

- Q:Procedures for producing common refractory materials?
- The general procedures of producing refractory materials include calcination of raw materials, selection of raw material , crushing, grinding, screening, mixing, ageing mixture, molding, drying, burning and etc. At present, the refractory factory usually purchases the calcined clinker, so the calcination of raw material is no longer a consideration of common refractory plants.
- Q:What is the principal part of silicious refractory material
- lightweight silica bricks, product with fused quartz, the silicon?dioxide content is generally greater than 93%, including silica?brick silicious refractory SiO2 as a main component of refractory products
- Q:What do we mean by saying that a ladle cover knots, elbow knots, blowpipe knots in refractory materials? What is the “knot”?
- Blowpipe is also the construction of unshaped refractory materials. Refractory material for ladle cover is light weight heat insulation refractory material. What you said that the construction of bend out refractory materials in some steel mills called "knot".
- Q:What's the classification of flameproof glass, the refractory time of fireproofing glass.
- According to different manufacturing technique, thermal insulation fire-resistant glass can be divided into grouting fireproof glass and composite fireproofing glass. Grouting fireproof glass has good thermal insulation performance, composite fireproofing glass has good fireproof?performance.
- Q:Which brand of AAA refractory is good?
- Rong Sheng Kerui quality refractory Zhengyuan Shenzhou Saatchi these brands are very good, with high refractoriness, durability and with a good cost performance. Get the majority of customers' recognition.
- Q:What is acid refractory material?
- In fact, with the content of zirconia refractory multiple theory should also be acid refractory
- Q:Which kind of external wall fire barrier zone material is better?
- The following types are: rock wool, aerated concrete, phenolic aldehyde and foam cement rock wool fire barrier zone "rock wool board" mainly uses water-repelling rock wool board produced by pendulum method as thermal insulation layer materia, and connecting and fixing base wall by binding and nail bonding, it is composed level A non-combustible building energy efficiency thermal insulation system by plastering layer composed by plastering mortar and glass?fiber mesh and decorative mortar finishing layer or coating. Good air permeability
- Q:What is the interior fireproof thermal insulation material?
- Polystyrene?board, extruded sheet and polyurethane are mainly used. Polystyrene?board is the cheapest, but the thermal insulation effect is ordinary. When absorbing water, it will deform. Other waterproof measures are needed to be made after insulating layer is done./
- Q:what's the classification of fireproof materials?
- Fireproof materials are used in construction, in various forms and it has played an absolute role in modern fireproofing, common fireproofing materials include fireproof?panel, fire door, fireproofing glass, fire?retardant?coating, fireproof bag,etc Or the material itself has a high temperature resistance, heat-resistant, flame-retardant properties. Most of them are used for the construction industry.
- Q:What is streaming fireproof material?
- Streaming fireproof material is castable refractory that can flow and degas without virbration, which is suitable for thin-wall or places that cannot be molded by vibration because of complex shapes. Well, appropriate amount of water is necessary for it. Its characteristic goes that it can be cast into various shapes of construction body without virbration and it will not reduce or not significantly reduce the performance of castable at the same time.
