摘　　要：烧结机头电除尘灰作为钢铁生产过程中的主要固体废弃物之一,若直接返回烧结利用,会对生产过程产生很大的负面影响,由于其中含有30%左右的铁,30%左右的氧化钾和4%左右的氧化纳,可以作为综合利用的资源。因此,烧结机头电除尘灰的资源化研究成为国内外学者的研究热点。文章简述烧结机头电除尘灰在钢铁工业中的产生过程,分析烧结机头电除尘灰的组成成分,详细地介绍国内学者和企业对烧结机头电除尘灰的综合利用现状,最后对烧结机头电除尘灰的资源化应用前景提出展望。As one of the main solid wastes in the iron and steel production process,the electrostatic precipitator ash of sintering machine head will have a great negative impact on the production process if it is directly recycled.Because it contains about 30%iron,about 30%potassium oxide and about 4%sodium oxide,it can be used as a resource for comprehensive utilization.Therefore,the research on the resource utilization of sintering head electrostatic precipitator ash has become the research focus of scholars at home and abroad.This paper briefly describes the production process of sintering head electrostatic precipitator ash in iron and steel industry,analyzes the composition of sintering head electrostatic precipitator ash,and introduces in detail the present situation of comprehensive utilization of sintering head electrostatic precipitator ash by domestic scholars and enterprises.Finally,the prospect of resource application of sintering head electrostatic precipitator ash is put forward.
