摘　　要：【目的】研究钢渣一次处理技术、回收利用方式和管理现状,深入分析钢渣利用率低的原因,并剖析钢渣利用面临的挑战。【研究现状】综述主流钢渣一次处理技术的工作原理及特点,包括热闷法、热泼法、滚筒法、水淬法、风淬法;总结钢渣在钢铁行业、水泥和建筑行业、微晶玻璃和陶瓷生产、污水处理、农业化肥生产、功能材料方面的综合利用现状;总结在选择钢渣的一次处理工艺时,必须综合考虑如钢渣的利用途径、节能环保要求以及投资效益等众多因素,钢渣的一次处理技术在国内外钢铁企业中的应用呈现多样化特征。【结论与展望】虽然钢渣在建材、农业、污水处理、陶瓷等领域已有一定程度的应用,但距大规模、高附加值的应用还相差甚远;发展高利用率、多极化的钢渣一次处理技术,加大钢渣综合利用,是钢渣一次处理技术领域的关键。Significance The choice of primary treatment technology for steel slag has a significant impact on its subsequent processing and utilization.This paper briefly outlines the primary treatment technologies and comprehensive utilization methods for steel slag,providing a review of their working principles,advantages,and disadvantages.Technologies such as the hot-braising process,rotating drum process,and hot-pouring process are discussed.Given the current state of steel slag utilization,this paper also summarizes the challenges restricting its application and proposes improvement technologies and strategies for steel slag recycling.Progress When selecting primary treatment methods,multiple factors should be considered,including its potential uses,energy conservation,environmental impacts,and economic benefits.The diverse applications of the primary treatment technolo-gies for steel slag in major steel mills worldwide result from the differences in steelmaking equipment,processes,the physico-chemical properties of the slag,and its utilization in later stages.In China,steel slag is primarily used in metallurgical indus-try,particularly for iron beneficiation.After hot steel slag undergoes primary treatment and multi-stage crushing,magnetic sepa-ration is used to recover slag steel from the steel slag for steelmaking,recover magnetic separation powder for sintering,and tail-ings for building material utilization.As a result of the increasing scarcity of river sand due to mining restrictions,steel slag as building materials in construction is expected to increase,which could help address the large stockpiles of steel slag.Conclusions and Prospects China faces large production quantities but low utilization rates for steel slag with large amounts stored in open piles,occupying land and posing environmental risks such as heavy metal leaching.Although steel slag has been used in various sectors,including construction,agriculture,wastewater treatment,and ceramics,it remains largely underuti-lized in large-scale,high-value a
