摘　　要：铁矿石烧结是钢铁制造中重要的铁前流程,是高炉炼铁的主要精料来源,也是钢铁行业实施“双碳”战略的前沿阵地。烧结终点、混合料水分以及FeO含量作为烧结过程中的关键参数,直观反映了烧结全流程的工况、能耗水平以及成品质量,是烧结过程在线检测的重点研究对象,本文重点阐述了这三个关键参数的检测方法研究现状,从工艺机理和参数特性出发,分析了现有检测方法的优缺点以及适用性,概括了当前烧结过程关键参数检测面临的问题,并对未来发展趋势进行了展望。Iron ore sintering is an important pre-iron process in iron and steel manufacturing,the main source of concentrate for blast furnace ironmaking,and the forefront of the implementation of the"double carbon"strategy in the iron and steel industry.As the key parameters in the sintering process,the sintering end point,the compound moisture and the FeO content intuitively reflect the working conditions,energy consumption level and finished product quality of the whole sintering process,which are the key research objects of on-line detection in the sintering process.The research status of the detection methods of such 3 key parameters is emphatically expounded,the advantages,disadvantages and applicability of the existing detection methods are analyzed from the process mechanism and parameter characteristics,the problems faced by the detection of key parameters in the current sintering process are summarized,and the future development trend is prospected.
