摘　　要：根据某钢厂环保整体规划要求,结合钢渣实际生产情况和现场条件,对国内同行、相关行业进行了充分的考察和调研,确定了钢渣处理后返生产和社会化利用方向,在此基础上,完成了钢渣二次加工处理线工艺设计和设备选型。钢渣二次处理线设计并成功投产,给国内同行提供了借鉴:在设计钢渣二次处理线时,应结合钢渣原料条件,并充分考虑处理后产品应满足返生产利用及与社会化利用对接,提高钢渣资源的综合利用率;钢渣二次处理线应采用成熟、可靠、先进的生产工艺及装备,集中处置,先粗选后精选,减量化、清洁化生产;金属提纯采用干法磁选,相对于传统的湿法磁选处理,不仅占地面积小,而且尾渣可以直接利用。According to the overall environmental protection planning requirements of a steel mill,combined with the actual production situation and site conditions of steel slag,the domestic peers and related industries were fully investigated,and the direction of steel slag recycling and social utilization after treatment was determined.On this basis,the process design and equipment selection of steel slag secondary processing line were completed.The design and successful operation of the steel slag secondary treatment line provide a reference for domestic peers:when designing the steel slag secondary treatment line,the conditions of steel slag raw materials should be combined,and the treated products should be fully considered to meet the requirements of return production and docking with social utilization,so as to improve the comprehensive utilization rate of steel slag resources;The steel slag secondary treatment line should adopt mature,reliable and advanced production technology and equipment with centralized disposal,roughing before selection for reductionary and clean production.Metal purification adopts dry magnetic separation.Compared with traditional wet magnetic separation,it not only occupies a small area,but also the tailings can be directly used.
