摘　　要：为深入研究有害金属和烧结矿碱度对高炉冶炼的影响,分析了有害金属Pb、Zn、Ni的来源及其对冶炼的不利效应,并提出从原料控制到过程优化的综合治理对策;同时,分析了烧结矿碱度的测定方法及不同碱度对烧结矿性质、炉料反应和炉渣流动性的影响,并提出了从原料配置到在线控制的碱度调控策略。研究表明,必须降低有害金属含量,并将烧结矿碱度控制在最佳范围,才能获得良好的冶炼质量和高效率。In order to deeply study the influence of harmful metals and sintered ore alkalinity on blast furnace smelting,the sources of harmful metals such as lead,zinc,and nickel and their adverse effects on smelting were analyzed,and comprehensive governance strategies from raw material control to process optimization were proposed.At the same time,the determination method of sintering ore alkalinity and the influence of different alkalinity on sintering ore properties,furnace charge reaction,and slag flowability were analyzed,and an alkalinity control strategy from raw material configuration to online control was proposed.Research has shown that it is necessary to reduce the content of harmful metals and control the alkalinity of sintered ore within the optimal range in order to achieve good smelting quality and high efficiency.
