本文介绍结构钢、工具钢、弹簧钢、不锈钢、高速钢、轴承钢和高温合金钢等我厂冶炼的800多种合金钢(包括碳素结构铜和碳素工具钢)的XRF光谱分析方法,讨论了标准试样的选择与文件设计、基体元素间干扰以及基体效应的校正等问题,并提出消除粒度效应的方法,提高了测量精确度。 This paper introduces the XRF spectral analysis method of more than 800 kinds of alloy steels (including carbon structural copper and carbon tool steels) smelted in our factory such as structural steel, tool steel, spring steel, stainless steel, high speed steel, bearing steel and high temperature alloy steel, The problems of selection and file design of standard sample, interference between matrix elements and correction of matrix effect are discussed. The method of eliminating the effect of granularity is proposed and the measurement accuracy is improved.
