Description

technical field

[0001] The invention relates to a method for quantitative analysis of non-metallic inclusions in steel, which belongs to the technical field of material physical property detection. Background technique

[0002] The content of inclusions is a sign of the cleanliness of steel, and the quantity, size, type and distribution of inclusions in steel significantly affect the properties of steel. Therefore, the quantitative detection of non-metallic inclusions in steel plays a vital role in the steel used in many industries such as machinery, automobiles, and aerospace.

[0003] The reported methods for direct detection of inclusions generally include metallographic method, electrolysis method and spectroscopic analysis method: the spectroscopic analysis method is realized by a spark spectrometer, and the results given can provide information on the quantity and type of inclusions in steel, but The current technology is not mature enough and has not reached the leve...
