Recent Advances in the Fundamentals and Kinetics of Steelmaking Reactions

摘要

G. R. Belton was the leader in developing our understanding of the kinetics of metallurgicalreactions. Selected recent kinetic studies, based on this understanding and the application of the results to actual processes are presented in this paper. In particular, the rates of reaction of carbon and carbon in iron with CO_2 and H_2O gases and FeO in slag are reviewed and applied to the iron smelting process. In addition, our basic understanding of the kinetics of the nitrogen reaction with iron is reviewed and the results are used in comprehensive models which can predict the nitrogen content in steel as a function of operating variables in the BOF, EAF and vacuum degassing.
