摘要
介绍了目前国内外高炉渣、钢渣等冶金熔渣处理、回收利用技术的进展,重点概述了滚筒法、风淬法、离心粒化法等干法粒化技术的研究进展和发展趋势,并对比分析了熔渣各种干式处理工艺的优点和不足;介绍了物理法、化学法两种熔渣显热回收途径。最后得出结论:离心粒化法的粒化及显热回收效果最好,将是熔渣回收和利用的主流工艺。
The current status of the recovery and utilization of molten slag (including blast fumace slag and steel slag, etc). Three kinds of dry granulation processing technology, including drum granulation, air blast granulation and centrifugal granulation are summarized. The advantages and the disadvantages of various treatment processes compared in the present discussion. The technology of sensible heat recovery of molten slag by chemical means and physical means are introduced. It is found that centrifugal granulation has the best effects of granulating and sensible heat recovery of molten slag. It will be a mainstream process of the recovery and utilization of molten slag.
