摘要
以刚玉为主要原料 ,并辅以纯铝酸钙水泥和其它外加剂 ,研制出了Al2 O3含量达 98% ,CaO含量 2 %的自流浇注料 ,其烧后体积密度 2 .98g·cm- 3,常温耐压强度 94.4MPa ,常温抗折强度2 0 .4MPa,均超过了国外同类产品的性能指标。
A kind of self flow castable which contains ~98% Al 2O 3 and ~2% CaO was processed from corundum and pure calcium aluminate cement as well as some addtional agents. Its bulk desity after sintering is 2.98g·cm -3 ,cold crushing strength is 94.4MPa, bending strength at room temperature is 20.4MPa.Its performance index are higher than those of the imported products.
