Abstract

A spectral analysis device for determining the additions to the steel and an apparatus for generating laser beams are connected via adjustable and switchable couplable optical waveguides to the agitating gas nozzles disposed in the bottom of a converter, the radiation passing through the agitating gas nozzles being converted via metallized agitating gas nozzles and photoamplifiers to measurable intensities.
