The invention provides an infrared image spectrum sampling detection method of online high-temperature parts, which integrates infrared image recognition and selective infrared image spectrum technology into the sampling detection of online high-temperature parts. Using infrared image recognition technology, multiple high-temperature parts on the production line can be identified and automatically randomly selected; then, using selective infrared spectroscopy technology, the emission spectrum of the selected high-temperature parts or selected positions can be detected, and the characteristics of each spectral sample can be extracted Peak wavelength, the modeling operation of the principal component of the sample set composed of spectral characteristic peak wavelength, combined with spectral analysis technology for high-temperature parts inclusion analysis. This method does not need to wait until the high-temperature parts are cooled to detect, and can identify multiple infrared images on the production line and automatically detect them randomly. , efficient, non-contact safety method.
Description
technical field [0001] The invention relates to the fields of infrared image spectrum application and high-temperature parts detection, and more specifically, relates to an online high-temperature parts infrared image spectrum sampling detection method using selective infrared image spectrum technology. Background technique [0002] The non-destructive and non-contact detection of high-temperature parts and the screening of inclusion parts are important research directions in the field of alloy production. [0003] With the increase in the use of alloy materials in industry, its importance becomes more and more prominent, and if impurity metal is mixed in the melting process, it will greatly affect the performance of parts, and even cause safety accidents. For example, in the history of aviation flight, many flight accidents were caused by the failure of the engine due to the fracture of titanium alloy parts. Inclusions will cause stress concentration and produce microcrack...
