Abstract
When steel smelted in a basic oxygen converter at an increased specific hot iron consumption rate of 950 kg/t and over, the slag formation process proceeds with deviations from the specified oxygen-lancing conditions under viscous slag formation during the converter turndown. Solutions are proposed to normalize the slag formation including dissolution of lime. This allows stabilizing of the slagging and lancing conditions, as well as preventing long downtimes of the equipment.
