摘要： PURPOSE:To improve analyzing accuracy when a steel sample is analyzed by a light emitting spectrochemical analysis method by quenching the steel sample at specified temperature or higher beforehand, and performing analysis. CONSTITUTION:A steel sample 1 is attached to a light emitting stand 5. Discharging is performed between the sample and an electrode 3 in an Ar atmosphere 2 under the optimum conditions of a discharging circuit 4. The light generated by the discharge is guided into a diffraction grating 9 through a condenser lens 7. The light undergoes spectroscopy for every component. The intensity of the spectroscopic spectrum 8 of the spectral light is measured with each photomultiplier 10. Then, the measured intensity of the light undergoes A/D conversion in a microcomputer 12 and further converted into the content of the component with a data processing system 13. Here, the steel sample 1 is quenched at 800 deg.C or higher (about 800-1,000 deg.C), and light emitting spectrochemical analysis is performed. Then, the texture within the plane to be analyzed is made uniform, and the carbon analyzing accuracy can be improved.
