Direct Reading Spectrometry of Sulfur in Steel Factors

Measures: (1) in the original calibration curve based on the samples of the unit, making on-site calibration curve. (2) The type of standardized self-control samples, using standardized self-control sample type curve analysis of samples. 4.4 Preparation of samples for analysis of sample preparation have significant impact, in particular a greater impact on the sulfur. General requirements for the sample surface to clean,[link widoczny dla zalogowanych], clear lines,[link widoczny dla zalogowanych], no porosity, trachoma. Have pores, trachoma, will affect the excitation effect, make the results high. Unclear lines also have an impact on the measurement results, the daily work of testing was done with a sample grinding, unclear lines, and infrared analysis of carbon and sulfur analyzer control, the results of large deviations, and then re-polished clear lines of, then Results and infrared carbon and sulfur analyzer value of close to 4.5 the temperature of the sample proved that the sample temperature on sulfur determination results have an impact, the higher the temperature the greater impact. So excited in the process of sample preparation or sample, if the sample temperature should be cooled to near room temperature, the sample,[link widoczny dla zalogowanych], then determined. Segregation of sulfur is 4.6 sample segregation of steel elements in one easy to [3]. Steel in the cooling process, is gradually cooled from outside to inside, the temperature is higher than the edge of the center temperature,[link widoczny dla zalogowanych], causing enrichment of sulfur segregation to the center, easy determination of the results led to larger deviations. Obtained when the sample was in the slow cooling, to avoid acute Lau Law 4: Optical Direct Reading Spectrometry Sulfur in steel of 793 cold and analysis should stimulate 3 points at least, stimulate the point distribution to be uniform. 4.7 The accuracy of standard operation condition after the above factors inspectors were learning organization,[link widoczny dla zalogowanych], united in the laboratory methods of operation, test results have improved significantly, Table 2 for the standard operation of the statistics situation. 5 Conclusion Table 2, the accuracy of statistics after the standard operation (, l-120) Direct Reading Spectrometric Determination of sulfur in steel influenced by many factors, only in the actual operation of careful observation, clear factors and take effective measures to be accurate and reliable test results, so as to effectively guide the steel production and improve the quality of steel.
