【 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.
【 bauxite sintering aluminum magnesium production process and methods of the spinel 】 :
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.
【 bauxite sintering aluminum magnesium spinel the characteristics 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.
【 bauxite sintering aluminum magnesium spinel performance 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.
