Melting Characteristics and Wettability of Binding Phase in Sinter

The melting characteristics and wettability of the binding phase in high basicity sinter were studied. By changing nCaO∶nFe2O3 （molar ratio of CaO to Fe2O3） as well as the percentage of MgO,SiO2,and Al2O3,the melting characteristics and wettability of the binding phase were discussed. The results indicated that the characteristic melting temperature was the lowest and wettability was the best at nCaO∶nFe2O3=1∶1 （without addition）; the addition of MgO increased the characteristic melting temperature and contact angles; when the percentage of SiO2 or Al2O3 was 3%,the characteristic melting temperature was the lowest,whereas the contact angles increased with an increase in SiO2 and Al2O3 contents.

含氟烧结矿粘结相润湿性研究

以包钢含氟烧结矿的粘结相为研究对象,考察了粘结相的物性随粘结相组成的变化规律。通过改变粘结相的碱度及MgO、CaF2和FeO的含量研究了不同成分粘结相的熔化特性及其熔化后对Fe3O4的润湿性。研究结果表明:碱度变大,MgO含量增加使粘结相的熔化温度升高,润湿角增大;CaF2和FeO能降低粘结相的熔化温度和润湿角。
