    • PURPOSE: Ultrafine alumina powder castable without having cement is provided for more strength than an existing castable by using an electrostatic interaction of ultrafine alumina powder as a binder at low temperature and high temperature, and for abrasion resistance, erosion resistance, explosion resistance and less contraction. CONSTITUTION: Ultrafine alumina powder castable without having cement comprises 30-45 wt.% of alumina having 3-10mm of a particle size; 9-20 wt.% of alumina having 1-5mm of a particle size; 15-27 wt.% of alumina having 1-0.074mm of a particle size; 5-15 wt.% of alumina having 150-250 mesh of a particle size; 5-17 wt.% of alumina having 200-400 mesh of a particle size; 5-15 wt.% of ultrafine alumina having 500-1,500 mesh of a particle size; and 1-10 wt.% of inorganic binder having 150-250 mesh of a particle size, less than 40 wt.% of silica sand and higher than 60 wt.% of alumina. Moreover, the ultrafine alumina powder castable adds one more compound from silica fiber or steel fiber.
    • 目的:通过在低温高温下使用超细氧化铝粉末作为粘合剂的静电相互作用,提供不含水泥的超细氧化铝粉末,比现有浇注料具有更强的强度,并具有耐磨性,耐腐蚀性,耐爆炸性和较小的收缩 。 构成:不含水泥的超细氧化铝粉末浇注料包含30-45重量%的具有3-10毫米粒径的氧化铝; 9-20重量%的具有1-5毫米粒径的氧化铝; 15-27重量%的具有1-0.074毫米粒度的氧化铝; 5-15重量%的具有150-250目粒度的氧化铝; 5-17重量%的具有粒径为200-400目的氧化铝; 5-15重量%的具有500-1,500目粒度的超细氧化铝; 和1-10重量%的无机粘合剂,其具有150-250目的粒度,小于40重量%的硅砂和高于60重量%的氧化铝。 此外,超细氧化铝粉末浇注料可从二氧化硅纤维或钢纤维中再添加一种化合物。
