Abstract

Abstract

Steel slag is a solid waste discharged from the steelmaking process. It has the characteristics of large annual output, high temperature, complex chemical composition, high hardness and poor stability. Under the carbon peaking and carbon neutrality goals, its treatment and resource utilization attracted attention again. In view of the characteristics of steel slag, this article summarizes the domestic and foreign steel slag treatment and utilization, and points out the problems in the existing treatment technologies and resource utilization methods. The resource utilization of steel slag under the carbon peaking and carbon neutrality goals is discussed, and we believe that steel slag waste heat recovery, molten steel slag reduction modification, and CO₂ capture are the focus of the future steel slag treatment.
