摘 要：Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use.Due to the depleting reserves of traditional high grade iron ore,there have been considerable changes in iron ore resources available throughout the world,especially in steel mills in East Asia.Corresponding to the changes in the availability of iron ore resources,the amount of impurities in iron ore has been slowly increasing.Some of these impurities have been found to have deleterious impacts on sinter quality and sintering performance.In the mean time,an increasing number of large blast furnaces with inner volumes of more than 5000 m3have been built,which require more sinter and are often more demanding in terms of the quality requirements of the ferrous materials.Finally,sinter plants are facing increasing pressures and more stringent regulations regarding their environmental impact.This paper gives an overall review of a variety of technologies developed worldwide to tackle the changing raw material characteristics and mitigate emissions from sintering operations.
