Direct Reading Spectroscopy for the Determination of Nitrogen in Alloy Steel
Using the furnace front laboratory of Hansteel Company as a platform,the ARL3460 direct reading spectrometer was used to analyze nitrogen in steel.Through research on sample preparation method,analysis condition selection,interference element correction,and work curve calibration,a scheme for rapid quantitative detection of nitrogen content in steel using direct reading spectroscopy was proposed.The results of nitrogen analysis by the spectrometer were compared with those of ONH-2000 nitrogen using production samples.Practice has shown that this scheme is feasible.
