Phosphorous Determination during the Oxygen Blow
Controlling Phosphorous levels during the steelmaking process has always been difficult. With the increased use of iron ores containing high Phosphorous, the measurement of Phosphorous at end point in BOF steelmaking continues to be a subject of interest because of the impact of Phosphorous on steel quality. BOF slag is complex in nature and contains several oxides like CaO, SiO2, P2O5, MgO, MnO, and FeO etc. Towards the end of blow the kinetics of different reactions slows down such that slag composition approaches a kind of pseudo equilibrium with metal. Thus, application of (thermo-dynamical) models alone for direct estimation of Phosphorous distribution does not yield sufficient reliable information for start tapping decision.
