摘　　要：机头灰是钢铁冶金烧结工序产生的一种固体废弃物,其中含有大量的碱金属、氯和一定的铅锌等重金属元素。如果直接返回烧结配料会降低烧结矿质量,从而降低高炉的技术经济指标。本文从机头灰的基础物化性能出发,综述了机头灰中有价元素综合利用技术现状,结合机头灰处理的最新技术分析了各工艺的优缺点和适用范围,指出机头灰综合利用中存在的问题以及相关处理技术的发展趋势,期望通过对机头灰综合利用的系统分析为钢铁企业资源综合利用提供有益的参考和借鉴,促进机头灰中有价元素的高值化资源化利用,实现钢铁生产的绿色发展。Head ash is a kind of solid waste produced by the sintering process of iron and steel metallurgy,which contains a large amount of heavy metal elements such as alkali metals,chlorine and a certain amount of lead and zinc.If the sintering ingredients are returned directly,the quality of the sinter will be reduced and the technical and economic specifications of the blast furnace will be reduced.Based on the basic physical and chemical properties of head ash,the current status of the comprehensive utilization technology of valuable elements in the head ash is revieved,the advantages and disadvantages of each process and the scope of application combined with the latest technology of head ash treatment are analyzed,the existing problems,and development trends in the comprehensive utilization of the head ash are pointed out,expecting to provide a useful reference for the comprehensive utilization of resources in iron and steel enterprises through the systematic analysis of the comprehensive utilization of the head ash to promote the high-value resource utilization of valuable elements in the head ash and realize the green development of steel production.
