铝镁尖晶石属于一种铝镁氧化物，其次要成分为氧化铝和氧化镁。铝镁尖晶石有自然构成和人工分解两种，其化学式为MgAL2O4或许Mgo•AL2O3。尖晶石实践含量为：MgO=28.3%M,AL2O3=71.7%。自然镁砂尖晶石极少发现，工业上使用的铝镁尖晶石全副都是人工分解的。分解铝镁尖晶石的两个次要办法是烧结法和电熔法。少数尖晶石资料是由高纯分解氧化铝和化学级氧化镁制成，即在竖窑烧结和在电弧炉内电熔。
【铝矾土基烧结铝镁尖晶石的消费工艺和办法】：
铝矾土基烧结铝镁尖晶石才有AL2O3含量76%以上的优质铝矾土和MgO含量95%以上的优质轻烧镁粉，通过多级均化工艺，在超低温隧道窑中经1800℃以上低温烧结而成。
【铝矾土基烧结铝镁尖晶石的特点与使用】：
铝矾土基烧结铝镁尖晶石具备良好的抗腐蚀、抗侵蚀、抗剥落才能强，抗渣功能好，抗磨蚀才能强，热稳固性好。耐低温等功能特点。是消费水泥回转窑低温带用铝镁尖晶石砖、钢包衬砖、钢包浇注料等耐火资料的理想原料。铝镁尖晶石宽泛用于耐火资料、钢铁冶炼、水泥回转窑及玻璃工业窑炉上。
【铝矾土基烧结铝镁尖晶石的功能与作用】：
铝镁尖晶石具备良好的抗腐蚀才能、抗磨蚀才能、热震稳固性好。其次要的用处：一是替代镁铬砂制作铝镁尖晶石砖用于水泥回转窑，岂但防止了铬公害，而且具备良好的抗剥落性；二是铝镁尖晶石用于制造钢包浇注料，大大进步钢板衬的抗腐蚀才能。使其宽泛使用于炼钢用耐火资料。优质预分解尖晶石的制取为不定形及定形高纯耐火资料的消费提供了新的原料。
【烧结尖晶石的优点】：
该工艺是一个延续的陶瓷化进程，管制窑中给料速度和平衡的温度散布，产生十分平均的晶体尺寸为30-80μm及低气孔率（3%）的产品。

【 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.
