[0031] 1 Determine the analysis conditions as follows:
[0032]
[0033]
[0034]
[0035] 2. Preparation of type standardized samples and analysis samples: use nickel-based high-temperature alloy steel to manufacture analysis samples, type standardized samples are obtained from daily production analysis, and the smelting and rolling process is basically the same as the analysis sample material, with accurate chemical composition inside Sample. The surface roughness of the analysis surface of the analysis sample is less than 0.8;
[0036] 3. Make a calibration curve: Under the selected working conditions, excite the standard sample of the photoelectric direct reading spectrometer, and each sample is excited at least 3 times, take the average value of the relative intensity of each element to be measured as the ordinate, and take the standard sample The concentration value of this element draws a calibration curve on the abscissa;
