摘要

Many common direct reduced scrap substitutes contain significantly higher levels of phosphorus as compared with scrap. As increasing quantities of scrap substitutes are used in EAF Steelmaking for the production of higher quality steels, control of phosphorus levels in the metal will become a concern. The goals of this research include the development a more complete understanding the behavior of phosphorus in DRI during EAF Steelmaking. The paper reports the results of a fundamental phosphorus kinetics study, as well as characterization of and experiments with several commercial direct reduced iron products. A process model based on laboratory experiments and plant trials will also be presented.
