以济钢球团竖炉为背景 ,根据生产观察、实验测试和理论分析 ,研究了竖炉球团干燥存在的问题及成因、危害及强化干燥的措施。结果表明 :球团干燥存在的主要问题是干燥不彻底且不均匀 ;其成因是烘床底部球团“滞留”、顶部球团“超越”及干燥气源不足等 ;主要危害是限制了竖炉产量、降低成品球质量及增加工序能耗。最后指出 ,炉外预干燥是强化生球干燥的有力手段 Taking the steel shaft furnace of Jinan Iron and Steel Group as the background, according to the observation of production, experimental test and theoretical analysis, the problems, causes, hazards and drying measures of shaft furnace pellet drying were studied. The results showed that the main problems of pellet drying were incomplete and inhomogeneous drying; the main reason was the “stranded” pellets at the bottom of the drying bed, the “transcendence” of the top pellets and the shortage of dry gas source. The main hazard was the limitation of shaft furnace Yield, reduce finished ball quality and increase process energy consumption. Finally, the out-of-oven pre-drying is a powerful means of strengthening the drying of pellets
