Spectral analysis method of non-white ball milling cast iron element chemical content

The invention relates to a spectral analysis method of non-white ball milling cast iron element chemical content, and employs a direct-reading spectrometer to analyze non-white ball milling cast iron element chemical content, and the element content obtained by the analysis is identical to the data obtained by a wet method. Compared with the wet method analysis, the spectral analysis method provided by the invention shortens the analysis period, and simultaneously acids are not needed in the analysis process, thereby the spectral analysis method of non-white ball milling cast iron element chemical content is good for protecting environment and keeping health of the operating personnel, and is more economical and more practical.
