建材院自1980年开始研究钢纤维增强耐火浇注料作水泥回转窑窑口衬料。目前由于窑口温度较高,原用的衬料使用寿命仅30～100天,最短的仅半个月。提高衬料的使用寿命应从改善衬料抗热震、抗冲击及耐磨损性能出发,钢纤维的加入可以大幅度提高这些性能。1.强度性能:钢纤维掺入后,抗折 Building Materials Institute since 1980 began to study the steel fiber reinforced refractory castable cement kiln kiln lining material. At present, due to the high temperature kiln mouth, the original lining of the service life of only 30 to 100 days, the shortest only half a month. Improve the lining of the service life should be to improve lining thermal shock resistance, impact resistance and wear resistance starting, steel fiber can greatly improve these properties. 1. Strength properties: After the incorporation of steel fibers, bending
