Analytical methods based on atomic emission spectroscopy are capable of simultaneously measuring multiple elements. They can be powerful tools in process control especially when sample preparation is simple and not time-consuming. In the present paper, elemental analytical techniques utilizing the lasers and a glow discharge emission spectrometry (GDOES) are reviewed with regards to their applications for steelmaking process control. They are different from the conventional spark discharge optical emission spectrometry (SDOES) in the atomization, the generation of plasmas and their characteristics. Accordingly, these techniques have been developed to make use of their properties in the applications for steelmaking processes. GDOES is characterized by its ability in rapid depth profiling and has been utilized in analyzing surfaces of materials including galvanized steels. Laser-induced breakdown spectrometry (LIBS), one of the main laser spectroscopic techniques, has been applied for rapid evaluation of steel defects taking advantage of laser’s pointability. LIBS is also distinguishable from other methods in its capabilities in stand-off and contactless analyses. The prospect of a direct analysis of molten steel, using lasers in particular, is also mentioned.
