High Alumina Bricks are manufactured with alumina or other raw materials containing higher alumina content through molding and firing. High Alumina Brick can resist acid slag erosion resistance because of its neutral refractory property. High Alumina Bricks have high thermal stability and refractoriness over 1770ºC. According to different Al2O3 content, High Alumina Bricks can be classified into Three Grades in China. Grade I High Alumina Bricks have more than 75% Al2O3 content. Grade II High Alumina Bricks have 60~75% Al2O3 content. Grade III High Alumina Bricks have 48~60% Al2O3 content. Production Advantage: 1.High refractoriness. 2. Good spalling resistance and wear resistance. 3. Good corrosion resistance. 4. Good thermal shock resistance. 5. High mechanical strength. 6. High-temperature creep rate is low.    Production Application:      These bricks are widely used as the hot face linings on tunnel kilns and shuttle kilns. For most high temperature kilns, the kiln car platform is built using bubble alumina bricks. In most cases, the bricks are available in shapes such as rectangular, arch, end arch, key and wedge. Bricks with tongue and grooves are also available on request. Remark:    250 pcs/ton, 4kg/pcs.    The data is the form is standard indicator, we also provide customized service.
