The main goal of this RFCS project was to be able to obtain some process control in steelmaking with respect to inclusion characteristics. The pre-requisite for this is state-of-the-art PDA optical emission spectrometry (OES) and advanced data treatment, highly developed in previous projects. The overall workplan was to transfer this technology into actual process control; test, evaluate and improve it to an effective tool. This required some development in process sampling, OES data collection, data treatment algorithms, artificial intelligence techniques and reference materials (RM) for verification of analytical results.
Process based steel cleanliness investigations and rapid metallurgical screening of inclusions by modern PDA techniques
