Abstract

The formation of Al2O3 inclusions in liquid iron has been investigated in a resistance heated tube furnace to obtain deoxidation and reoxidation related data. The formation of inclusions during the early stages of deoxidation was simulated by bringing a piece of Al in contact for a short time with liquid Fe containing different dissolved oxygen levels. Reoxidation was studied by exposing Al containing Fe melts to a CO/CO2 atmosphere. Through modeling, an estimate of the local and time-dependent growth conditions for the inclusions can be made and linked to the inclusion characteristics.
