The invention discloses a method for rapidly testing casting blank segregation by utilizing a direct-reading spectrometer, which is suitable for the quantitative and trending detection in the casting blank segregation, belonging to the technical field of metallurgy analyzing and detecting. In the method, the direct-reading spectrometer is adopted to simulate an in-situ analyzer to detect the casting blank segregation; and the direct-reading spectrometer segments and dots a test sample, and simulates the in-situ analyzer to analyze the test sample, so as to quantitatively detect the continuously cast blank macrosegregation. The method can overcome the defects that the in-situ analysis sample preparation is complex, the testing period is long, the detection cost is high and the like, satisfies the generalized quantitative detection to the casting blank in the continuous casting production, and provides a good popularization and reference method for the iron and steel enterprises owning rapid spectrum analyzers in the trending and quantitative detection of the continuously cast blank segregation. Compared with the traditional pickling method for detecting the casting blank segregation, the method has the same trend on the description of the casting blank segregation as that of the pickling method; the casting blank segregation result detected by the direct-reading spectrometer not only can describe the casting blank segregation condition, simultaneously can clearly describe the component segregation curve of each element, and has the visual digitized function.
Description
technical field [0001] The invention relates to a method for rapidly inspecting slab segregation by using a direct-reading spectrometer, and is especially suitable for quantitative and trend detection of slab segregation in iron and steel enterprises. The invention belongs to the technical field of metallurgical analysis and detection. Background technique [0002] With the rapid development of rapid detection technology, the application of rapid spectral analysis in iron and steel enterprises has been rapidly promoted. Due to its convenience, speed and accuracy, rapid spectral analysis has played an important role in efficient production, energy saving and consumption reduction. It has been well applied in the rapid detection of components. At present, the daily inspection method for the internal quality inspection of continuous casting slabs is to carry out sulfur stamping or pickling inspection for each casting. The detection of defects cannot meet the digital quantitat...
