摘　　要：为明晰当前烧结制粒工艺的发展进展及未来发展的趋势,对钢铁企业烧结制粒工艺与设备进行了充分的总结与分析。烧结制粒性能直接影响着料层透气性以及准颗粒结构分布,是钢铁企业烧结工序中重要的环节,长期以来铁矿石烧结工序的热态性能受到较多关注,但制粒性能欠缺重视。近年来,随着理论和工艺的发展,烧结制粒受到钢铁企业越来越多的重视,随之针对制粒也采取了诸多工艺与设备的优化措施。首先阐述了烧结制粒优化的意义,进而总结了近些年来国内外钢铁企业在原料预处理、滚筒设备、生石灰消化以及混合料水分监测4个方面针对制粒做出的优化进展,并基于对烧结制粒的理解和新兴人工智能技术的认识展望了在可预见的未来钢铁企业烧结制粒优化的趋势。In order to clarify the current development progress of the sintering granulation process and future development trends,the sintering granulation process and equipment of steel enterprises have been fully summarized and analyzed.Sintering granulation performance directly affects the air permeability of the materials layer and the distribution of quasi-particle structure and it is an important link in the sintering process of iron and steel enterprises.For a long time,the thermal performance of the iron ore sintering process has received more attention,while the granulation performance has not been paid much attention.In recent years,with the development of theory and technology,sintering granulation has received more and more attention from iron and steel enterprises and then many optimization measures of technology and equipment have been adopted for granulation.First,the significance of sintering granulation optimization was explained and then the optimization technologies made by domestic and foreign steel enterprises in the four aspects of raw material pretreatment,mixer equipment,quicklime digestion,and mixture moisture monitoring in recent years were summarized.The understanding of sintering granulation and the knowledge of emerging artificial intelligence technologies help to look forward to the trend of sintering granulation optimization in steel enterprises in the foreseeable future at the end.
