Optical emission spectroscopy as a method to improve the process automation of electric arc furnaces and ladle furnaces

The steel industry is on its way towards more environmentally friendly steelmaking. To achieve the ambitious goals of significant CO2 emissions reduction, new processes, practices, sources on-line data, and digitalization together with automation will be required. address these issues, this paper discusses optical emission spectroscopy (OES) as an data acquisition method for industrial electric arc furnaces ladle furnaces. current state OES a measurement in prospects applications are presented examples based authors’ prior research.
