Spalling-Resistant Alumina Bricks
| This kind of products are special in China. The main raw materials are bauxite of super quality and some content of Zirconia. The thermal shock resistance at 1100℃ by water could be more than 40 cycles. After the reheating in the kilns, they are of super quality in resistance of flaking, alkali corrosion, and have the property of low thermal conductivity. In the cement kiln of 2000-5000TPD, these bricks could be used in cooling zone, transition zone, calcining zone, precalciner, hood of kiln gate, grate cooler and other positions. Specification for reference: Al2O3 70% min ZrO2 5-8% Apparent Porosity 20-23% Bulk Density 2.5-2.6g/cm3 Refractoriness 1790 ℃ min CCS 70MPa min RUL 1500 ℃ min Thermal Shock Resistance(1100℃/water) 40 cycles min |
