摘　　要：我国钢渣产生量大,资源化利用率低于30%。目前钢渣堆存量超10亿t,导致土壤及水体的严重污染,提高钢渣资源化利用率是解决这些问题的重要途径。对钢渣在回收含铁料、返回烧结、用于道路和建材等方面的应用进行研究,并基于钢渣产量大、温度高的特点,给出未来钢渣应加强在余热回收方面研究,同时加大钢渣在道路和建材领域的利用,使得钢渣得以大量消纳,助力“双碳”目标的实现。The amount of steel slag produced in China is large,and the resource utilization rate is less than 30%.At present,the stock of steel slag exceeds 1 billion tons,resulting in serious pollution of soil and water.Improving the resource utilization rate of steel slag is an important way to solve these problems.In view of this,this paper summarizes the application of steel slag in the recovery of iron bearing materials,return sintering,road and building materials.Based on the characteristics of large output and high temperature of steel slag,it is proposed that in the future,the research on waste heat recovery of steel slag should be strengthened,and the utilization of steel slag in the field of roads and building materials should be increased,so as to make a large amount of steel slag absorbed and help achieve the goal of"double carbon".
