1.Structure of Calcined Bauxite Description

Cement Factory Raw Material Natural Bauxite of  Bauxite  Size 0-5mm for Turkey

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

Cement Factory Raw Material Natural Bauxite of  Bauxite  Size 0-5mm for Turkey

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:Can quantitative feeder be used in refractory plant? Thank you
Feeder experts, justice and analysis, quantitative feeder, of course, can be used in refractory plants
Q:What is the use of refractory?
It is equivalent to a protective layer. It can be used to protect structural materials from being direcctly attecked by high tempereture or internal gases. General structural materials are steel, so the main function is resistant to fire and high temperature. In literal meaning, refractory is a fireproof material. Steel is easily deformed and wore. Structural materials can not directly touched with solid and liquid. Refractory materials are generally used as a protective lining of structural material, so it is necessary to be protected.
Q:what's the requirements of refractory for forge furnace?
High temperature resistance, good slag resistance.
Q:What refractories are resistant to fluorine gas?
It is recommended to use fused-quartz brick, which will produce hydrofluoric acid fluorine (an acidic gas) when water vapors. It is cheap. While it is recommended to use silica brick if it exceeds 1,200 degrees. So acidic refractory is an advisable refractory for using. It works well if the temperature is below 1200 degrees.
Q:What are the types of advanced refractory?
According to the chemical composition of minerals,refractory can be divided into eight categories: 1, siliceous material. 2, aluminosilicate materials. 3, magnesia materials. 4, dolomite materials. 5, chromium materials. 6, the carbonaceous material. 7, zirconium materials. 8, special refractories. 1. refractories according to chemical properties can be divided into three categories: 1, acidic refractory materials. 2, neutral refractories. 3, basic refractories. 1. refractories according to chemical properties can be divided into three categories: 1, ordinary refractories, refractoriness is 1580-1770 degrees. 2, advanced refractories refractoriness is 1770-2000 degrees. 3, super refractories refractoriness higher than 2000 degrees. 3. refractory according to the forming process can be classified into seven categories: 1, natural rock molding process. 2, compression moulding refractories. 3, moulding refractories by casting. 4, plastic molding refractories. 5, ramming molding refractories. 6, injection molding refractories. 7, extrusion molding refractories.
Q:Application of refractory materials in petroleum industry
Our natural gas transportation, chemicals, equipment, packing, safety, insulation, and even building materials are available.
Q:What is the upper temperature limit for refractory materials?
Different materials are different. In the professional field, there is a triangulation cone softening point experiment as a reference for using the upper temperature limit.
Q:whether the fire resistant level of aerated concrete building blocks can reach the grade one?
it has fire resistant level, incombustible material,and it should reach grade one level.
Q:Why does refractory need to add coarse firstly and then add fine aggregate?
Binding agent can wrap particles and improve binding effect.
Q:What a blast furnace refractories generally?
refractories for blast furnace include carbon brick and silicon-aluminum refractory. BF carbon brick inlcudes half-carbon charcoal bricks, microporous charcoal brick, ultra porous charcoal bricks, graphitic brick and mould pressing charcoal brick. tiles and molded graphite small charcoal bricks. I hope my answers above are helpful to you and your ideal anwers.
