High alumina refractory castable for rotary kiln
The invention relates to high alumina refractory castable for a rotary kiln. The castable is prepared from, by weight, 20-30 parts of high alumina slag with granularity of 0-2 mm, 18-28 parts of high alumina slag with granularity of 2-5 mm, 17-27 parts of high alumina slag with granularity of 5-10 mm, 15-25 parts of superfine alumina powder with granularity of 200 meshes, 2-6 parts of fine silica dust, 2-6 parts of high alumina cement with granularity of 200 meshes, 3-10 parts of aluminum mote with granularity of 200 meshes, and 2-3 parts of sodium hexametaphosphate with granularity of 1-3 mm. The high alumina refractory castable for the rotary kiln is prepared with high alumina slag recovered from smelting slag as aggregate and high alumina fine powder as a matrix, waste resources are secondarily used, production cost is greatly reduced, economic benefits are remarkably improved, and the pollution of waste materials to the environment is reduced; meanwhile, the performance of refractory castable is remarkably improved, and the service life is prolonged to a certain extent as well.
