摘　　要：转炉钢渣是炼钢过程中产生的大量固体废弃物,目前国内对于转炉钢渣利用率相较国外还是很低,大量的转炉钢渣由于没有得到利用造成浪费和环境污染。介绍了转炉钢渣的组成成分、理化性质以及矿物性质,通过钢渣粉化及其特性,分析制约钢渣利用的因素,最后总结钢渣处理后的应用途径,例如建筑材料、农业生产、道路工程或回填材料和烧结材料等方式。基于钢渣目前存在的问题以及钢渣本身的性质,结合工业发展方向和需求,展望钢渣未来的发展。Converter steel slag is a large amount of solid waste generated during the steel-making process.Currently,the utilization rate of converter steel slag in China is still very low compared to foreign countries,and a large amount of converter steel slag is wasted and caused environmental pollution due to not being utilized.The composition,physical-chemical properties,and mineral properties of converter steel slag have been introduced in the text.Through the pulverization and characteristics of steel slag,the factors that restrict the utilization of steel slag have been analyzed.Finally,the application pathways of steel slag treatment have been summarized,such as building materials,agricultural production,road engineering,backfill materials,and sintering materials.Based on the current problems of steel slag and the properties of steel slag itself,in combination with the direction and demand of industrial development,the future development of steel slag has been expected.
