Abstract
Optical emission spectrometry is superior to other analytical methods in its rapidity. Therefore, it plays an important role in the field of elemental analysis at the steel making plants. However, further speedup and labor saving of the analysis by automation are required to progress of continuous steel making process. An apparatus has been developed to meet this need, and the following results were obtained.(1) Analytical procedure was fully automated, from the receipt of samples to the transmission of analytical results. The time required for the analysis of a sample is 50sec.(2) Automatic standardization and automatic selection of working curves were also provided.(3) Better precision results were obtained than by the conventional integration method in the analysis of routine steel samples taken from a converter by employing the pulse height distribution analysis method.
