Improvement of inclusion flotation during RH treatment

Objectif

The general objective of this multi-national multi-partner research project is to develop a validated model of prediction of the evolution of the inclusion population during RH treatment, to evaluate the effect of ladle slag composition on the capture of inclusions and finally to propose an optimised flotation process at the RH unit. A chemical engineering model will be developed and associated to fluid dynamic computations to predict the evolution of inclusion size distribution during RH treatment of various steel grades (ULC and special alloyed Al killed steels). It will take into account the agglomeration of solid inclusions, the reoxidation phenomena by slag or air intakes and the ability of slag to entrap inclusions as well as thermal effects. Final validation of the models will be done from experimental characteristics of liquid steel cleanliness obtained on industrial RH.
