对如何采用X射线荧光仪检测钢中的各主要稀土元素,然后再计算出稀土总量的方法进行了研究。通过对分析条件、最佳计数时间、试样研磨深度等项目进行探讨,建立了一套快速分析钢中稀土总量的方法。实践证明,该方法可快速、准确地检测出含量在0 005%以上的稀土总量,完全可以满足生产的需要。 How to use the X-ray fluorescence spectrometer to detect the major rare earth elements in the steel, and then calculate the total amount of rare earth were studied. Through the analysis of the analysis conditions, the best counting time, the depth of the sample grinding and other projects, a set of rapid analysis of the total amount of rare earth steel. Practice has proved that this method can quickly and accurately detect the content of more than 0 005% of the total amount of rare earth, fully meet the production needs.
