摘　　要：废旧铝已经成为铝合金熔铸业的重要原料,如何在工业条件下对其进行成分识别与保级再生是铝合金熔铸行业的关键问题之一。通过对比γ射线、激光诱导击穿光谱分析(LIBS或LIPS)以及X射线等成分识别方法,提出了它们各自的应用模式和"固态废旧铝牌号化识别"的新概念。在现有废杂铝再生工艺的基础上,提出了基于"固态牌号化识别+液态精确分析"识别模式的废杂铝保级再生工艺流程,该流程为解决废旧铝再生流程中需要反复进行成分调整的问题提供了一个新的途径。Scrap aluminum is an important raw material of aluminum alloy casting industry.It is a common and key issue how to identify its composition and regenerate former grade under industrial conditions.The application mode and the new concept ＂solid state aluminum scrap grade identification＂ has been presented by comparing the component identified method throughγ-rays,laser-induced breakdown spectroscopy component identification（LIBS or LIPS）and X-rays.The aluminum scrap regeneration process of ＂identification＋liquid-solid grades accurate analysis＂ has been presented,based on the existing aluminum scrap recycling process.The process is a new way to overcome the problems which need component adjustment repeatedly in waste aluminum regeneration process.
