Abstract

Abstract

Based on the developed model of decarburization and denitrogenation in VOD for ultra clean ferritic stainless steel,the oxygen utilization rate for decarburization and the denitrogenation ability at different initial carbon contents were studied in the oxygen-blowing decarburization stage. The decarburization and denitrogenation ability were analyzed during the VCD stage. The effects of carbon content at the oxygen blowing end on decarburization process and temperature control were discussed to provide technical supports for optimizing the VOD operation.
