The methods of the treatment with the blast furnace slag at the present time: RASA, IN-BA, TYNA and OCP were commented. These methods exist the problems including consuming so much water, low energy utilized coefficient and the contamination emission such as sulphide, etc. The new developing method - blast furnace slag dry granulation can solve the problems and it is the treatment of utilizing the blast furnace slag.%阐述了拉萨法(RASA)、因巴法(INBA)、图拉法(TYNA)、底滤法(OCP)等当前高炉渣处理工艺的技术现状,认为目前的高炉渣处理存在水耗大、炉渣显热利用率低和硫化物等污染物排放的问题.拟开发的高炉渣干式粒化工艺能有效解决这些问题,是高炉渣处理利用的发展趋势.
