摘要
钢渣是炼钢过程的副产物,我国目前年产量接近1亿t,但综合资源利用率较低。简述了钢渣的产生特点,综述了其资源化利用和稳定化研究现状。钢渣组成中含有较多的游离氧化钙,导致钢渣在利用过程中体积膨胀,稳定性较差,建材化利用是消纳钢渣的重要途径,但需要解决钢渣稳定性差的问题,高温热闷技术具有钢渣稳定性效果好、处理时间短的优势,是目前应用较多的稳定化技术,也是解决钢渣利用率低的重要途径。
Steel slag is a by-product of steelmaking process.The producing of steel slag in China is proximately100million tons,but the utilization ratio of comprehensive resources is the lower.This paper described the production and composition characteristics of steel slag,reviewed current situation and progress of resource utilization and stabilization of steel slag.Steel slag contains more free calcium oxide,which results in volume expansion and poor stability in the process of utilizing steel slag.The utilization of steel slag resource utilization can be divided into process reuse,preparation of ceramics,materials for environment treatment and building materials utilization,among which steel slag building material will be the most important way to utilizing steel slag,but the problem of poor stability of steel slag should be solved.The hot stifle technology has the advantages of good stability and short treatment time,which is the most used technology for steel slag stabilization.
