阐述了当前国内外高炉渣处理技术使用现状,认为水淬法渣处理技术存在新水消耗大、炉渣显热利用率低和二氧化硫、硫化氢等污染物排放的问题,提出开发高炉渣干式粒化技术有望同时解决其渣粒化及热量回收的问题,是高炉渣处理工艺的发展趋势。
The current status of blast furnace slag treatment technology at home and abroad is expounded. It is considered that the problems of new water consumption, low sensible heat utilization rate of slag and emission of pollutants such as sulfur dioxide and hydrogen sulfide exist in the technology of slag treatment by water quenching. Chemical technology is expected to solve the problem of slag granulation and heat recovery at the same time, which is the development trend of blast furnace slag treatment process.
