Description
| - The paper deals with the method of quantitative wave dispersive X-ray spectral micro-analysis used for measurement of the mass concentration of carbon in the continuously cast steel block. The main conditions for preparation of metallographic sections from the samples taken from continuously cast blocks are described, if the samples are designated for determination of the carbon concentration by the above mentioned method. These conditions must be unconditionally adhered to in order to ensure a reproducibility of the measurements of the mass concentrations of carbon. A limit of detectability of carbon and of errors of the measurements of carbon at the measurement on the limit of detectability at the measurement of its mass concentration on the spectral line C K α with use of the standard Fe3C is given. The proposed method of measurement of the carbon concentration was applied for simultaneous determination of the distribution of mass concentration of carbon, manganese, silicon and phosphorus in nine samples taken from the continuously cast block made of unalloyed steel. Concentrations of these four elements were in individual samples measured in the segment with the length of approx. 1 mm at100 points with the use of an analytical complex JEOL JXA-8600/KEVEX DELTA V-Sesame and wave dispersion analysis (VDA). Mathematical-statistical processing of the results of measurement showed that the carbon concentration can be determined in a reproducible manner and that it is possible at the same time to explain its relationship with the distribution of simultaneously analysed elements – manganese, silicon and phosphorus in the structure of the continuously cast steel block.
