Method for rapidly testing casting blank segregation by utilizing direct-reading spectrometer

Abstract

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.
