摘要
合金熔体纯净度直接决定铸件质量,因此纯净度检测尤为重要,现阶段大多数企业采用铸锭断口杂质含量判定合金熔体纯净度,误差较大、反馈时间长。本文综述了几种较为先进的含渣量检测方法,包括基于电子感知空间的Li MCA,过滤法的Po DFA、Prefil-Footprinter、LAIS、Qualiflash,能谱分析EDX和断口渣含量的K模,能够实现在线检测,对合金熔体的净化提供指导。
The quality of casting is determined directly by purity of molten alloy. The purity detecting of molten alloy is particularly important. At present, most enterprises determined the purity of molten alloy by impurity content in ingot fracture, and the error is large and the feedback time is too long. In this paper, several advanced methods for measuring slag content are reviewed, including LiMCA based on electronic perception space, PoDFA, Prefil-Footprinter, LAIS, Qualiflash based on filtration method, EDX based on energy-dispersive X-ray and K mold based on impurity content in ingot fracture. It can realize on-line detection and provide guidance for the purification of alloy meltting.
