Fused zirconia corundum brick is also called AZS, which is abbreviation of zirconia corundum brick . The zirconia corundum is kind of white solid, made by pure aluminum oxide, 65% purity zirconium oxide and silicon dioxide 34% purity, cooled in the model after melting into the electric melting furnace. Its petrographic structure is consisted of zirconium corundum and plagioclase eutectoid and glass phase. From the phase of speaking, it is eutectoid phase zirconium corundum and oblique stone body. The glass phase is filled between their crystals. Fused zirconia corundum brick is mainly used in glass industry kiln. Wanhao is a manufacturer who is specialized in designing various kinds of furnace and making refractory products for electric furnace, ladle, tundish, blast furnace, AOD furnace, IF furnace, etc. Article Source: The application of fused zirconia corundum brick Company name: Wanhao Refractory Email:sales100@wanhaorefractory.com Website: http://www.wanhaor...

Corundum bricks are high alumina refractory fire bricks made for extreme demands. The alumina content in corundum brick is from synthetic corundum of high purity, such as white fused alumina or tabular alumina. Additional ingredients are special refractory clays, reactive alumina, and very pure modifications of silica. Corundum bricks are fired at high temperatures to form a matrix with mullite, mullite-corundum or corundum that has excellent volume stability. The service temperature for corundum brick goes up to 1800°C. Corundum bricks can be used in nearly all fields of industrial application where extreme high temperature and increased resistance against aggressive slags and atmospheres are necessary. Such properties or features of corundum bricks are necessary especially in the chemical industry and for the production of carbon black. The addition of chromium oxide, zirconium oxide, and phosphates gives the refractory bricks excellent structural flexibility, which...

Chrome corundum brick is alumina - chrome oxide as the main raw material production of high-performance, has the characteristics of high refractoriness , greatstrength, good thermal shock stability, strong ability to resist erosion, inuse, has the performances of scouring resistance, wear resistance, resistanceto spalling structure, has obtained the good effect in metallurgy, glass,carbon black, the petrochemical industry. Chrome corundum brick using rawmaterial is by the ratio of alumina and chromium oxide according tocertain proportion, go through high temperature melting synthesis of a solidsolution. Use special refractory materials production technology to makerefractory brick, can improve and enhance internal quality of the products,improve the high temperature performance of products. 1.Refractoryproperties of chrome corundum brick AddCr2O3 to high purity corundum material, no matter how much the amount is, notonly will not reduce the fire performance of materials...
