摘　　要：铁矿粉的同化性能、黏结相强度与液相流动性等基础特性是烧结优化配矿的重要基础。对BX、YLJ和NFJ等多种铁矿粉进行基础特性检测,并将2种及2种以上铁矿粉混合进行拓展研究。分析铁矿粉基础性能的主要影响因素和三大矿种的基础性能特征,提出基于同化性能、液相流动性的互补配矿思路,为增加性价比高的缺陷矿用量、提高生产质量、降低配矿成本提供理论指导。The basic characteristics of iron ore powder,such as assimilation performance,bonding phase strength,and liquid phase fluidity,are important foundations for realizing sintering optimization.Basic characteristic testing is conducted on various iron ore powders such as BX,YLJ,NFJ,etc.and two or more iron ore powders are mixed to expand the research.The main influencing factors of the basic performance of iron ore powder and the basic performance characteristics of three major ore types are analyzed.A complementary ore blending approach based on assimilation performance and liquid phase fluidity is proposed,which provides theoretical guidance for increasing the amount of defect ore with high cost-effectiveness,improving production quality and reducing ore blending costs.
