Summary Spinel is a rare mineral in nature, and it must be made by artificial synthesis. According to a certain proportion of raw materials, mixing pressing ball molding (to join the right amount of pulp). The characteristics of electric furnace melting temperature, in the smelting process, to maintain the redox state, avoid Fe2O3 FeO oxidation, to prevent the emergence of elemental Fe, after natural cooling of the hercynite sand. The uniform large crystal (95%) with no grain boundary was revealed under the microscope, which was similar to that of the glassy state. After processing into the iron aluminum spinel brick, mainly used in large-scale cement rotary kiln, instead of the current cement kiln used chrome brick, no Cr6+ pollution. Extended lining service life (magnesia chrome brick 10-12 months and hercynite brick 17-18 months), greatly reducing the consumption of refractory material and manpower, reduces the production cost, the full realization of the cement kiln chrome free production, solve the chromium pollution. Fe Al spinel represents a new generation of high performance chrome free refractories for cement rotary kiln. The two main methods for the synthesis of 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. 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. Natural magnesia spinel rarely found industrial applications of magnesium aluminum spinel are all artificial synthesis, the two main methods of synthetic magnesia alumina spinel is sintering and electric melting method. etc. Spinel application 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.
