摘　　要：综述了再生铝合金中铁的主要来源及其对性能的危害性,概述了目前再生铝合金除铁的常见方法,即重力沉降法、离心去除法、过滤法、电磁分离法和熔剂法,指出了除铁对扩大再生铝原料的应用和提高再生铝产品品质的重要意义,及适合再生铝生产的除铁熔剂广阔应用前景。The source of iron in recycled aluminum alloys and its harmfulness on properties are surveyed. The common iron removal methods from recycled aluminum alloys are introduced, such as gravity settling, centrifugal segregation, filtration, electromagnetic separation and flux. The significance of iron removal to widen the application of recycled aluminum alloys and improve the quality of recycled aluminum products is presented. Among the iron removal methods, the flux for iron removal is the one with potentially promising application for the production of the secondary aluminum industry.
