ABSTRACT

      Application of modern methods of X-ray fluorescence spectrometry in the analysis of the
                                      metallurgical materials

First part of the presentation is concerned with the summary of contemporary used analytical
methods and technical possibilities of instruments in analyses of materials from metallurgical
processing. Currently used methods of wet-way chemistry are replaced with more effective
spectrometric analytical methods in most laboratories. Due to large variability of the process
controlling samples that are supplied by the Metallurgical and Chemical laboratories is necessary
creating techniques for preparation individual materials for analyses and reduce the analyzing time
as well. For correct decision, what sample preparation technique will be used and what
spectrometric or combination of spectrometric and classical chemical methods may be used, is
necessary to know the history of sampling, and pre-preparations made by submitter of the analysis.
On the basis of the theoretical and practical knowledge, the practical techniques for preparation
and analyses of some samples from metallurgical production were suggested.  Laboratory works were
performed in ArcelorMittal Ostrava Corp. and elaborated for the needs of sample analyses from the
blast furnace and steel works productions.

            Second part of the presentation is concerned with practical results of the analyses of
particular materials applying suggested sample preparation techniques and X-ray spectrometric
methods utilizing calibration curve evaluation method and UniQuant 5, standardless program for
X-ray spectrometry. Records were discussed and techniques were applied analyzing samples from the
metallurgical production in Spectrometric laboratory.
