Abstract
On applying the emission spectrophotometric analysis to steel, we have usually determined using complicated corrections and layer-separated calibration curves in accordance with the difference ot its metallurgical history. Besides it couldn't be applied to irregular shaped samples such as the chipped and wire.
The following method was examined to solve above problems: melting irregular shaped samples such as the chipped, block and wire by Ar-arc melting furnace, casting as the bottom and determining by the emission spectrophotometric analysis.
It was showed that this method didn't require the correction by its metallurgical history and was satisfactory in regard of precision and accuracy.
Significant improvement in operation efficiency is expected by simultaneous determination of many elements by this method, compared with the chemical analysis as before.
