Abstract： The production of heavy plates for the oil and gas industry requires highest quality levels of the semi-finished products like slabs. Calcium-treatment at the end of the steelmaking process is essential. The composition of non-metallic inclusion is changed during this production step. Accurate analysis of inclusions is of main interest. An automated optical emission spectrometry-pulse discrimination analysis（OES-PDA） system makes statistical investigations of any steel sample possible. OES-PDA is used to detect the basic micro cleanness parameters like content and composition. Targeted automated raster electron microscope energy dispersive X-ray analysis (REM-EDX) gives more detailed information about non-metallic inclusions and verifies the OES-PDA data sets. The combination of both results show new detailed information about the process, especially magnesia containing inclusions during solidification of slabs.
