【 magnesium aluminium spinel introduction 】 :

 

Magnesium aluminum spinel belongs to a kind of aluminum and magnesium oxide, the main components in aluminum oxide and magnesium oxide. Magnesium aluminum spinel has naturally occurring and synthetic two kinds, the former is MgAL2O4 or Mgo style, AL2O3. Spinel theory content is: MgO style = 28.3% M, AL2O3 = 71.7%. Natural magnesia spinel rarely found that magnesium aluminum spinel in industrial application are all synthetic. Synthesis of magnesium aluminium spinel and fused two main methods are sintering method. Most spinel material is made from high purity synthetic chemical and alumina grade magnesium oxide, which in shaft kiln sintering and fused in arc furnace.

 

【The classification of magnesium aluminum spinel 】 :

 

Alumina magnesia and fused spinel with sintering, the method of two kinds of production process. Raw materials mainly magnesite and industrial alumina powder or bauxite. According to the index of magnesium oxide and alumina, magnesium rich spinel and rich aluminum spinel and applied to different fields.

 

A, according to the production process or method points: sintering alumina magnesia spinel (sintered spinel) and fused magnesium aluminium spinel, fused spinel).

Second, according to the production of raw materials can be divided into: bauxite alumina magnesia spinel with alumina aluminum magnesium spinel (sintered or fused).

 

1, bauxite sintering alumina magnesia spinel

 

Production technology of bauxite sintering aluminum magnesium spinel and methods:

Bauxite sintering aluminum magnesium spinel is AL2O3 content more than 76% of the high quality bauxite and MgO style content more than 95% of the high quality light burning magnesium powder, through multi-stage homogenization process, hitches in ultra high temperature tunnel kiln is above 1800 ℃ high temperature sintering.

 

The characteristics of the bauxite sintering aluminum magnesium spinel and application:

Bauxite sintering aluminum magnesium spinel has good erosion resistance, corrosion resistance, spalling resistance capability is strong, good slag resistance, abrasion resistance, good thermal stability. High temperature resistance and other characteristics. Is the production of cement rotary kiln thermal belt with alumina magnesia spinel bricks, ladle lining brick, ladle castable refractory materials such as the ideal raw material. Magnesium aluminum spinel is widely used in refractory material, steel smelting, cement rotary kiln and glass kiln.

 

The performance of the bauxite sintering aluminum magnesium spinel and function:

Magnesium aluminium spinel has good erosion resistance, abrasion resistance, good thermal shock resistance. Its main purposes: one is substituting magnesite chrome sand manufacture alumina magnesia spinel brick used in cement rotary kiln, not only avoid the chromium pollution, but also has good resistance to spalling; Second, magnesium aluminum spinel used in ladle castable, greatly improve the erosion resistance of steel lining. Make it widely used in steelmaking with refractory material. High quality of preparing for amorphous synthetic spinel and setting high purity of refractory production provides a new raw material.

 

The advantages of the sintered spinel:

This process is a continuous process of pottery and porcelain, control the temperature of the furnace feeding speed and the equilibrium distribution, have very uniform crystal size of 30-80 (including m and low porosity (3%) of the product.

 

2, the alumina base fused alumina magnesia spinel 】 :

 

Oxide production technology of fused alumina magnesia spinel and methods:

Alumina base fused alumina magnesia spinel is a purity of 98.5% or more light burned magnesia and distribution into the right amount of high purity magnesite (MgO style > 45.55%) such as mixtures. In the Canon of high temperature smelting electric arc furnace, and can be processed into different specifications and spinel powder particles of aggregate.

 

Alumina base properties and the application of the fused alumina magnesia spinel:

Alumina base fused alumina magnesia spinel is high temperature resistant, dense large, bibulous rate is low, small thermal expansion coefficient, good thermal stability, strong ability to resist erosion characteristics. Is made of casting skateboard, nozzle bricks, ladle brick and brick is the ideal material of open hearth furnace, magnesium aluminum spinel products of high temperature mechanical performance is good, is also a large cement kiln, neutral transition zone close brick, refractory pouring cement kiln and the basic materials of kiln furniture in high school. Widely used in iron and steel smelting, glass kiln cement rotary kiln level.

 

The advantages of fused spinel:

The representative intermittent operation of the process, the castable block need to extend the cooling time, in the microstructure of the casting block cooling leads to uneven, due to rapid cooling, outside of the spinel is smaller than the inside of the body, low melting point impurity concentration at the center, because need to sorting are fused spinel raw material.
