应用压块、焙烧方法，结合试样的显微结构及X射线衍射(XRD)分析，在固定的烧结温度与碱度的条件下，研究了不同高磷铁矿配比对烧结试样的显微结构和矿物组成的影响。结果表明随着高磷铁矿配比的增加，试样的显微结构由非均相结构向均相结构过渡；赤铁矿由粒状转变为熔蚀结构，铁酸钙由板状转变为针状；赤铁矿含量逐渐减少，铁酸钙含量逐渐增多。
Applying agglomerating, roasting method and combined with the microstructure and XRD analysis, the effect of sintering with allocating high-P iron ore on the microstructure and mineral composition was investigated at the conditions of a fixed sintering temperature and alkalinity. The results show that: with the increasing proportion of high-P iron ore, microstructure of samples has a transition from the non-homogeneous structure to the homogeneous structure, granular structure of hematite changes into the melting structure, calcium ferrate changes from slat into acicular, hematite content decreases while calcium ferrate increases.
