Factory Directly 85% Al2O3 1-3mm Calcined Bauxite with Low Price

 

1.Calcined Bauxite Description

A general term for a rock composed of hydrated aluminum oxides. It is the main ore of alumina to make aluminum.  Also used in the production of synthetic corundum and aluminous refractories. The bauxite is purified by the  Bayer Process. First the ore is mixed with a hot concentrated solution of sodium hydroxide. The NaOH will dissolve  the oxides of aluminum and silicon but not other impurities such as iron oxides, which remains insoluble. The  insoluble materials are removed by filtration.

 

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

calcined bauxite is typically calssified according to its intended commercial application,such as abrasive ,cement , chemical l, metallurgical, and refractory .as raw material for use in high alumina and super duty refratory bricks  and shapes ,plastics ,castable refratory, motors, gun mixes, ramming mixes, abrasive grains and other products chemical composition .

Q:How to detect the acid resistance of refractory? Is there any standard? Thank you
What material it is. There are many kinds of refractory materials, and I basically understand all petrochemical refractory.
Q:What's the classification of refractory material?
Magnesium aluminum is complex and mainly seeing what classification standard is like according to the appearance shape can be divided into two categories, setting and not setting according to the acid alkali can be divided into acidic, magnesia, high aluminum, ramming expected, spinel, spray coating, plastic, just the quality of the jade, daub material according to the chemical composition is divided into, such as clay, neutral and alkaline according to the operation mode can be divided into different castable, magnesium, calcium, magnesium chrome
Q:How can the furnace be replaced after the gasifier or water wall is replaced with refractory material?
The simplest is to find a refractory construction unit, should provide you with oven curve.
Q:How to choose thermal insulation materials for flood heating?
1, Select the appropriate floor material suitable for radiant floor heating. The floor radiant heating system mainly transfer heat through the ground concrete and the ground material to the room. Therefore in the heating season the ground material will always be heated during heating season. Therefore, it is better to choose stone materials and compround floor plate insensitive to tenmperature change with good heat dissipation and functions. Currently, wood floor is not suitable for the ground radiant heating system. 2, choose the pipe with anti permeability performance. Plastic floor heating pipe itself has a certain air permeability, if oxygen penetrates in it is prone to oxygen erosion and system's mental device will be eroded, resulting in the risk of leakage. Therefore in order to ensure the reliable operation of the heating system, the selected pipe must have anti oxygen permeation performance, and meet the standard stipulated by the DIN4726 oxygen permeation quantity: and be less than 0.1mg\L.d at 40 C.
Q:What kind of refractory material should be used for common boiler?
Build by using clay refractory mortar. Common clay brick is used as combustion layer. Xindeyuan Refractory Material, red brick is used as external wall. Light clay brick is used as thermal insulation layer, thank you.
Q:What brands are the best in the A-level refractory materials?
These brands are good.
Q:The performance of refractory material
As for easticity modulus, you can serach for information on the Internet or specialized books.
Q:For refractory, what is critical particle size? Thank you.
For example, in refractory technology, if there is an express of equal to or lower than 0.008mm, 0.008 refers to critical particle size. The main criterion for judging performance of three major continuous casting is the major three normal temperature indexes (compressive strength and anti bending strength at normal temperature, apparent porosity and bulk density). Does this criterion have any defect? How to do multiple test if high-temperature index introduced? Carbon bond is one of the three major castings. How does it form? What do you think of it? Hope someone explains it for me. Thanks a lot!
Q:which kind of refractory is used in golden smelting furnace? How about his using temperature
generally the price of the quartz sand refractory material is higher and the temperature can meet the requirement of 2000 degree.
Q:How many kinds of fireproof materials are there in the market?
I wonder that how many kinds of fireproof materials are there? Does anyone know about it, please tell me, thanks
