Ziel

TO ENABLE THE STEELMAKER TO MONITOR AND CONTROL INCLUSIONS IN STEELS, ESPECIALLY CONTINUOUSLY CAST STEELS, THE ANALYST MUST BE IN A POSITION TO IDENTIFY AND QUANTIFY THE VARIOUS OXIDISED INCLUSIONS. IN THE FINAL STEEL-MAKING STAGE, IT IS IMPORTANT TO KNOW THE DEGREE OF CLEANLINESS OF THE METAL AND THE DISTRIBUTION OF VARIOUS ELEMENTS BETWEEN METALLIC AND INCLUSION PHASES (ALUMINIUM-KILLED STEELS FOR EXAMPLE). IT IS THEREFORE NECESSARY TO OBTAIN THE MOST ACCURATE RESULTS POSSIBLE BY USING SUITABLE CHEMICAL METHODS OF ANALYSIS:

1) CHEMICAL ANALYSIS:
THE MEASUREMENTS WILL BE CARRIED OUT BY ATOMIC ABSORPTION AND OPTICAL EMISSION SPECTROMETRY WITH PLASMA BEAM EXCITATION
2) ELECTROCHEMICAL DISSOLVING:
STUDY OF ELECTROCHEMICAL SEPARATION METHODS CARRIED OUT BY DISSOLVING THE IRON MATRIX.
3) PHYSICAL ANALYSIS:
OPTICAL EMISSION SPECTROMETRY WITH MILD EXCITATION. AN ANALYSER OF THE LECO RO 316 TYPE WILL BE USED FOR THE OXYGEN PHASES.

THIS RESEARCH WILL HELP TOWARDS THE PRODUCTION OF NEW STEEL GRADES WITH A LOW CONTENT OF DEOXIDISING ELEMENTS.
