Abstract
A method for the on-line analysis of liquid steel was developed. By focusing the light of a pulsed Nd:YAG laser on to the liquid surface, a plasma was produced and examined with a spectrometer and an optical multichannel analyser, respectively. As a result, calibra-tion curves were obtained for several elements. Typical lower detection limits were in the range between 10 and 100 ppm.Keywords
