| 摘 要： | 钢渣是炼钢过程排放的固体废弃物,具有年产量大、温度高、化学组成复杂、硬度高和安定性不良等特点。在"双碳"目标下,其处理和资源化利用再次受到关注。针对钢渣特点,对国内外钢渣处理利用情况进行综述,指出了现有处理工艺和资源化利用途径存在的问题,并对"双碳"目标下钢渣的资源化利用途径进行探讨,提出钢渣余热回收、熔融钢渣还原改性和CO2捕获是未来钢渣处理方向和路径。

| 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. |
