摘　　要：钢渣在线重构是解决钢渣胶凝活性低、体积安定性差、化学波动大等问题,从而提高钢渣利用率的一种有效技术。本文简述了钢渣的的特性及存在的问题,并重点综述液态钢渣在线重构中调质组分、温度制度、冷却制度、气氛制度、均混制度、工艺设备以及热力学与动力学研究对重构钢渣胶凝活性和体积安定性的影响;最后针对于钢渣在线重构所存在的问题及钢铁行业中较先进的技术展望钢渣在线重构的发展趋势。The on-line reconstruction of steel slag is to solve the problems of low cementing activity, bad volume stability and high chemical fluctuation, so it is an effective technique to increase the utilization ratio of steel slag.The characteristics and existing problems of steel slag are briefly described in this paper. And the inflution of on online reconstruction in liquid steel slag temperature system, cooling system, air system, mixing system, process equipment and the research of thermodynamics and kinetics to slag cementitious activity and volume stability was focused. Finally, the problems existing in the on-line reconstruction of steel slag and the advanced technologies in the steel industry, and the trend of on-line reconstruction of steel slag is expected.
