钢渣循环利用研究现状及发展趋势

系统综述了钢渣处理的方法及其优缺点,对比分析了国内外在钢渣循环利用方面的研究现状。国内由起初开始利用钢渣制备水泥、陶瓷等材料过渡到回收有价金属和吸收固化CO2的研究,而国外在钢渣浸出固化CO2的理论可行性及现实可操作性做了广泛细致的研究。可以预见,钢铁企业利用钢渣以废治废是未来钢渣处理及再利用的切实可行的新途径。

Overview and trend of steel slag recycling and reuse

The present paper systemically discusses the advantages and disadvantages of methods tackling the steel slag and then analyzes and compares the current status of research on the steel slag recycling and reutilization at home and abroad,namely in China the research work starts from preparation of the cement and ceramic material out of the slag at the initial stage to the recycling and reclamation of certain rare metal and sequestration of the carbon dioxide in the later stage,whereas extensive and thorough studies on the feasibility of extraction and sequestration of the carbon dioxide out of the slag has been conducted theoretically and practically abroad.It can be predicted that it would be the practical new trend for controlling the gas emission with steel slag in near future.
