【摘要】 通过对我国废钢铁利用现状、废钢铁分类情况及分类标准进行分析，探讨了目前我国废钢铁利用及分类分拣概况，提出了存在的问题。在此基础上，对废钢智能识别系统、废钢铁快速检测技术的发展及应用情况进行分析，认为目前废钢铁分类分拣技术的发展水平与钢铁企业的实际需求仍有较大差距，未来要实现电炉智能化冶炼必须做到两种技术的耦合。我国对废钢铁的分类分拣仍相对初级和粗放，还不能做到对废钢铁成分的快速有效识别；在“双碳”背景下，随着我国钢铁工业由规模化高速发展阶段转向绿色低碳、高质量发展的新阶段，废钢铁质量的重要性日渐凸显，我国废钢铁利用水平要尽快得到提升，不仅要提高炼钢废钢比，更要提高废钢铁分类分拣的技术水平，为实现电炉冶炼智能化奠定基础。更多还原

【Abstract】 The current status of steel scrap utilization, classification, and classification standards in China were analyzed, the current situation of steel scrap utilization and classification sorting were explored, and the existing problems were put forward. On this basis, development and application of steel scrap intelligent identification system and rapid detection technology were analyzed. It is considered that there is still a big gap between the development level of steel scrap classification and sorting technology and the actual demand of steel enterprises. In the future, the coupling of the two technologies must be achieved in order to realize the intelligent smelting of electric arc furnace. The article points out that the classification and sorting of steel scrap in China is still relatively primary and extensive, it is not yet possible to achieve rapid and effective identification of the composition of steel scrap. Under the background of “dual-carbon”, as China’s steel industry shifts from the stage of large-scale and high-speed development to the new stage of green low-carbon and high-quality development, the importance of steel scrap quality is becoming more and more important. The utilization level of steel scrap should be improved as soon as possible, not only to improve the scrap ratio of steelmaking, more importantly, it is necessary to improve the technical level of steel scrap classification and sorting, so as to lay a foundation for the realization of intelligent smelting.更多还原
