Determination of Content of Primary and Secondary Elements in Particle Steel by XRF Method
In this paper,the preparation method and the determination method of the composition of the particle steel in melt sheet are studied.Glass fluxes were prepared by melting the crushed particle steel in a waxy lithium tetraborate wall-mounted crucible.Using 16 certified iron ore standard samples,2 certified manganese ore standard samples,4 control sam-ples of high purity iron powder and iron ore standard samples,2 control samples of iron ore and manganese ore standard samples,a total of 24 standard samples were used as calibration samples,the strength of each element was measured under selected conditions and the curve regression was carried out.The relationship between the standard sample concentration of each element in iron ore and the measuring strength was established.The mass fraction of each component in the particle steel was measured by experimental method.The precision and accuracy of the method meets the testing requirements,and it has the advantages of low cost,fast and convenient,and can completely meet the quality control of iron-making produc-tion.
