铁矿烧结工序是现代钢铁生产流程中必不可少的环节，但又是钢铁工业最大的微细颗粒物(PM10和PM2.5)排放源，占总排放量的40％左右.阐述了铁矿烧结过程PM10和PM2.5的排放特性，颗粒形貌及其物理化学性质；综述了国内外关于烧结过程微细颗粒物减排的最新研究进展，提出了烧结过程微细颗粒物减排研究的发展方向.
Iron ore sintering is an essential process in the modern iron and steel production,as well as the largest emission resource of the PM (particulate matter)accounting for about 40% of the total emission in the iron and steel industry.The emission characteristics and phy-chemical properties of PM10 and PM2.5 in the iron ore sintering were introduced,and the research development of PM emission reduction was also summarized.The potential fu-ture development of PM emission reduction in the iron ore sintering was also pointed out.
