| 发明名称 | Method for determining carbon in cast iron | ||
| 摘要 | A method of determining the carbon content of an iron alloy may include starting of the measurement of a sample in a spark spectrometer, creation of a plasma in a pre-sparking phase, detection and recording of an intensity signal for the carbon, calculation and cutting out of an unstable plasma phase, calculation of an excessive rise in the carbon signal, and calculation of the content of dissolved and undissolved carbon. | ||

| 主权项 | 1. A method of determining carbon content of an iron alloy, the method including: (a) starting measurement of a sample of the iron alloy in a spark spectrometer, (b) creating a plasma in a pre-sparking phase, (c) detecting and recording an intensity signal for carbon, (d) calculating and cutting out an unstable plasma phase, (e) calculating an excessive rise in the carbon intensity signal, and (f) calculating content of dissolved and undissolved carbon of the sample of the iron alloy. | ||
