摘要
探讨了应用能量色散偏振X射线荧光光谱仪测定生铁中锰和钛进行炉前快速分析的方法。对测定锰及钛时仪器的工作条件,试样的制备以及工作曲线的制作等因素作了较系统的试验,该方法所得测定结果与化学法测定结果或标样标准值相吻合,相对标准偏差小于1.5%,与化学法相比,锰和钛的测定时间由50 min缩短到2 min。
Polarized energy dispersive X-ray fluorescence spectrometry （EDXRFS） was applied to the at-line rapid analysis, especially for the determination of manganese and titanium, in the metallurgical process of iron and steel. The X-LAB2000 polarized EDXRF spectrometer was used in the analysis; A thorough study on the various factors of analysis, including working conditions of the spectrometer for the determination of Mn and Ti in pig iron, method of sample preparation, and preparation of working standard curve, was made and described. As compared with the chemical analytical methods used conventionally, consistent results of determination were obtained by the proposed method, with values of RSD＇s （n=ll） less than 1.5% and time of analysis for the 2 elements shortened from 50 min to 2 min.
