Problems solved by technology

The wet chemical method needs to select different methods for different elements to analyze the elements of the iron-based alloy one by one; if the inductively coupled plasma spectrometry is used, the iron-based alloy sample needs to be chemically pretreated, and then the ICP spectrometer is used for measurement, so this Both schemes have the disadvantages of long analysis period, cumbersome operation, and high test cost.
[0003] Fluorescence spectroscopy analysis is fast and the analysis period is short, but this method strictly depends on the spectral standard sample of the corresponding brand of iron-based alloy. Since the development of the spectral standard sample of iron-based alloy lags far behind the production of metal materials, the wide application of fluorescence method Restricted by the same brand iron-based alloy spectral standard sample
If the problem of iron-based alloy spectral standard sample can be solved, the application of fluorescence spectrometer will be greatly expanded, and the shortcomings of long analysis period, cumbersome operation, and high test cost can be avoided, and the chemical components in various iron-based alloys can be quickly analyzed to solve new problems. Composition detection problems of brand iron-based alloys

Abstract

The invention relates to an analysis method of the content of alloy elements, in particular to an element content fluorescence analysis method of iron-base alloy. According to the technical scheme, the method comprises the following steps: (1) measuring an iron-base alloy standard sample, and drawing a comprehensive standard curve; (2) determining an optimum measurement parameter of a fluorescence spectrometer; (3) analyzing the comprehensive standard curve, and determining a linear relation between the element characteristic X-ray intensity and the element content; (4) setting the content of each element in an iron-base alloy virtual synthesized standard sample; (5) drawing a single element virtual working curve; and (6) measuring the content of each element in the iron-base alloy to be detected by utilizing the single element virtual working curve. According to the element content fluorescence analysis method of the iron-base alloy, the intensity of the characteristic X rays of the element to be detected in the iron-base alloy sample is measured to obtain the content of the element in the iron-base alloy to be detected.
