Utilisation of iron ores (ironsands) with higher Ti content has prompted this BOF-based investigation into the effects of Ti on the removal of P from steel. A specific focus will be to separate the effects of Ti on the physical properties of the slag and the chemistry of phosphorous transfer from steel to slag. From a plant perspective, the thermodynamic and kinetic data obtained from high-temperature experiments will be incorporated into a) an operational model that accurately predicts the steel’s final phosphorous composition enabling a reduction in overall heat-to-heat time and increased productivity of the existing plant, and b) a flux usage model to optimize flux usage, plant practices and incoming phosphorous loads reducing the overall cost of converting iron ores into steel.
