high quality Refractory Chrome Corundum Brick for sale
Chrome corundum brick is made of corundum and fused chromium oxide as the raw material, mixed with micro powder and other additive, and then through mixing, shaping, drying, sintering in the high temperature shuttle kiln. chrome corundum block is widely used for linings of high temperature furnaces or kilns in many industries of steel, building material, non-ferrous smelt, light industry and chemical industry.
Chrome corundum brick refers to a corundum refractory product containing Cr2O3. At high temperature, Cr2O3 and Al2O3 form continuous solid solution, so the high temperature performance of chrome corundum products is better than that of pure corundum products. Chrome corundum fire brick is used in petrochemical gasifier should be low silicon, low iron, low alkali and high purity, and should have high density and strength.The content of Cr2O3 is in the range of 9%~15%
.High fire resistance,
.Big intensity,
.Good wear resistance,
.Good thermal shock resistance,
.Good acid and alkali resistance,
.Good chemical stability.
Chrome corundum brick is processed with post-al2o3, adding a certain amount of chromium oxide powder and fine powder of chrome corundum clinker, which are formed and burned at high temperature. The content of chromic oxide in sintered chrome brick is generally lower than that of fused cast chrome corundum brick. Chrome corundum block also use mud casting method of preparation, the alpha Al2O3 powder and chrome oxide powder mixing, add glue and organic adhesives made from thick mud, at the same time part of chromium corundum clinker, by grouting into adobe, firing again.
