以高碱度烧结矿中的铁酸钙粘结相为研究对象,考察了粘结相的流动性和液相生成能力;实验研究了不同n_(C_aO):n_(Fe_2O_3)以及不同氧化镁、二氧化硅和三氧化二铝的铁酸钙粘结相的流动特性和熔化时间。定义粘结相的流动性指数描述铁酸盐粘结相的流动性,用熔化时间来表示粘结相的液相生成能力。结果表明,n_(C_aO):n_(Fe_2O_3)=1:1时,粘结相的流动性和液相生成能力最好;添加氧化镁使粘结相的流动性和液相生成能力变差;添加适量的二氧化硅或三氧化二铝能改善铁酸盐粘结相的液相生成能力,但二氧化硅和三氧化二铝过多将使粘结相的流动性变差。
Taking cesium ferrite binder phase in high basicity sinter as the research object, the fluidity and liquid phase formation ability of the binder phase were investigated. The effects of different n_ (C_aO): n_ (Fe_2O_3) and different magnesia, Flow characteristics and melting time of the calcium ferrite bonded phase of silica and alumina. The fluidity index of the binder phase is defined to describe the fluidity of the binder phase of the ferrite and the melting time is used to indicate the liquid-phase-forming ability of the binder phase. The results show that the fluidity and liquid phase formation ability of the binder phase are the best when n_ (C_aO): n_ (Fe_2O_3) = 1: 1; the addition of magnesia deteriorates the fluidity and liquid phase formation ability of the binder phase; The addition of an appropriate amount of silica or alumina improves the liquid-phase formation ability of the ferrite binder phase, but too much silica and alumina result in poor fluidity of the binder phase.
