Bauxite

 

Introduction

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

 

1.Applications

Raw bauxite is typically classified 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 refractory bricks and shapes ,plastics ,castable refractory, motors, gun mixes, ramming mixes, abrasive grains and other products.

Q:How can refractory material of the electric furnace be used for longer.
I do not know if you are referring to super high power arc furnace for steelmaking, if you are, I have a easy solution for I have been doing this work.
Q:Who knows about the B-level fireproof insulation materials?
Organics, extruded sheet, polyphenyl board and phenolic resin. The fireproof performance of sea capacity module (fireproof and thermal insulation material) is B1-level with the heat conductivity coefficient of only 0.028w / m · k. It is a good choice. A-level: Rock wool, glass wool, silicate, aluminum silicate, calcium silicate, phenolic aldehyde, and foam glass. B-level: Rubber and plastic, extrusion molding, polyphenyl, PEF.
Q:How long is the fire endurance of the rock wool board?
Some time ago we did an experiment, the result is no change in the burning 30 minutes. The following is the picture of rock wool after the test .
Q:What is neutral refractory? Can refractory suppliers tell the main components of it?
The material using Al2O3, clay, bauxite and corundum as the main components is neutral material; the material using MgO and CaO as the main components is basic material; the material using SiO2 as th emain component is acidic material.
Q:what are the types of piping insulation material fire rating?
There are two grades: 1, the organic material: Grade B Grade B1 hard combustion (fire retardant) 2, inorganic materials: class A no burning it is divided into three levels, attributed to the types of materials!
Q:What are the requirements on fire resistance period of C-level fireproof glass?
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. 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.
Q:What are the classifications of refractory? Which category does steel ladle castable belong to?
Silmo brick, alumina-magnesia brick; 2. coke oven, aluminum silicate... 8 categories)& nbsp, teeming ladle, glass furnace ...... 7 categories) high alumina refractory products (blast furnace, electric furnace, cement kiln, magnesia, glass furnace; 3. high alumina refractory mortar (high alumina, glass kiln ...... 6 categories) special refractory products (magnesia-carbon bricks, aluminum-carbon bricks, MgO-C, shapeless refractory products& nbsp, light weight, sliding plate bricks, cement kilns: There are 26 categories in refractory products, clay, calcium silicate, ceramsite lightweight... 10 categories) & nbsp, air heating furnace, sheets; 1 refractory castable (alumina-magnesia, blocks, resistance furnace... 11 categories) alkaline refractory products (magnesia. First, thermal insulation refractory products (ceramic fiber; clay, diatomaceous earth, steel fibre reinforcement...14 categories) & nbsp, silicon carbide brick ...... 19 categories) Second, China is the largest refractory production country in the world, clay, non-water cannons mud, converter, siliceous, teeming ladle, profiled) siliceous refractory products (coke oven, dense shaped refractory products (all kinds of bricks, electric furnace roof, glass kiln ...... 5 categories) clay refractory products (blast furnace, high alumina ...... 4 categories) three
Q:What are the differences of ceramics and refractories? Is the ceramics belonging to refractories?
No In the high school chemistry, the former is talking about the traditional inorganic material, the latter is belonged to the new materials.
Q:Who knows what is the standard of insulation material whose fire proof is level A?
Level A is distinct from B in coefficient of fire proofing. Level A is non combustible, while Level B is divided into B1( flame retardant), B2(combustible) and B3( inflammable). Currently in the market, level A materials are as follows: phenolic, rock wool, insulation mortar, ceramic foam, foam glass, and foamed concrete. The most advantageous of level A material at present is foamed concrete, also known as foamed cement. Xuzhou Lvchuang Construction company is working on this, you can search fro it on the internet, it has high cost performance.
Q:Pals who know something about fire resistant material please tell me how many types of refractory material there are
Classified into ordinary and special refractories. The ordinary refractory material is calssified into acid, neutral and alkaline according to the chemical property. Special refractory material is calssified into high temperature oxide according to the composition for , infusible compound and high temperature composite in addition, can be divided into ordinary refractory products according to the fire intensity (1580 ~ 1770 DEG C), high-grade refractory products (1770 ~ 2000 DEG C) and special refractory products (2000 DEG C above). According to the products shape can be divided into bulk (standard brick, special-shaped brick block, special shape (crucible, sagger, pipe, etc), fibrous shape (silicates of aluminum and zirconium oxide and boron carbide matter) and irregular shape (fireclay, refractory castables and incompletely material).
