【产品介绍】
铝镁尖晶石属于一种铝镁氧化物，其主要成分为氧化铝和氧化镁。铝镁尖晶石有天然形成和人工合成两种，其化学式为MgAL2O4或者Mgo•AL2O3。尖晶石理论含量为：MgO=28.3%M,AL2O3=71.7%。天然镁砂尖晶石极少发现，工业上应用的铝镁尖晶石全部都是人工合成的。合成铝镁尖晶石的两个主要方法是烧结法和电熔法。多数尖晶石材料是由高纯合成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。
【产品分类】
铝镁尖晶石采用烧结法和电熔法两种生产工艺。原料主要是菱镁矿和工业氧化铝粉或铝矾土。按氧化镁和氧化铝的指标不同，分富镁尖晶石和富铝尖晶石并应用不同领域。
一、按生产工艺或方法分：烧结铝镁尖晶石（烧结尖晶石）和电熔铝镁尖晶石（电熔尖晶石）。
二、按生产原料可以划分：铝矾土基铝镁尖晶石与氧化铝基铝镁尖晶石（烧结或电熔）。

【英文翻译】
Al Mg spinel is a kind of aluminum magnesium oxide, its main component is alumina and Magnesium Oxide. Al Mg spinel has two kinds of natural formation and artificial synthesis, and its chemical formula is MgAL2O4 or Mgo AL2O3. The theoretical content of spinel is: AL2O3=71.7%, MgO=28.3%M. Natural magnesite spinel rarely found, aluminum magnesium spinel industrial application are synthetic. The two main methods for the synthesis of Al Mg spinel are sintering and electric melting. Most spinel material is made from high purity synthetic alumina and chemical grade magnesium oxide, namely in shaft kiln sintering and fused in arc furnace.
[product category]
Two kinds of production processes of aluminium and magnesium spinel by sintering and electric melting. Is the main raw material of magnesite and industrial alumina or bauxite. According to the indexes of Magnesium Oxide and alumina, magnesium rich spinel and alumina rich spinel were used in different fields.
One, according to the production process or method points: sintered aluminum magnesium spinel (sintered spinel) and fused magnesia alumina spinel (fused spinel).
Two, according to the production of raw materials can be divided into: Bauxite Based spinel and alumina spinel (sintered or fused).
[product use]
Sintered magnesia alumina spinel is used for cement rotary kiln, which not only avoids chromium pollution, but also has good resistance to spalling. Sintered magnesia alumina spinel is used for making ladle pouring material, which can greatly improve the anti erosion ability of steel sheet lining. The preparation of high quality synthetic spinel provides a new raw material for the production of amorphous and amorphous high purity refractory materials.
Electric melting magnesium aluminum spinel is manufacturing plate, nozzle brick, open hearth brick material. The high temperature mechanical properties of aluminum and magnesium spinel products are good, which are the basic raw materials of the filter belt, refractory casting material and high. Fused magnesia alumina spinel used in iron and steel smelting and glass industry furnace.
[product packaging]
25kg/ bag, double woven bag packaging, export tons of bags can be used, can also be adjusted according to customer requirements for production.
