摘　　要：不锈钢渣因含有Cr6+而对环境产生危害,并且在渣的堆放过程中Cr3+向Cr6+转化一直在持续着,因此为降低不锈钢生产的成本、减少资源消耗和保护生态环境,钢渣应尽快给予无害化处理及综合利用。不锈钢渣无害化方法有高温还原法(干法)、还原法(湿法)和固化法。不锈钢渣综合利用的方向是解决钢渣有害元素硫、磷富集的问题,实现钢渣再生,进行企业内部循环,同时尽量减少钢渣的外部利用。Stainless steel slag is harmful to the environment due to Cr6＋,and transformation from Cr3＋ to Cr6＋ is carrying on continuously when the slag is piling up.Therefore harmless processing and comprehensive utilization should be made as soon as possible.Innocuous treatment methods include high-temperature reduction（dry method）,water-leaching reduction（wet method） and solidification.The comprehensive utilization trend of the stainless steel slag is to resolve the problem of enrichment of harmful sulfur and phosphorus and realize the slag regeneration in order to promote internal recycle of the slag and reduce the external utilization.
