【 摘 要 】

The ultimate goal of the project was to develop a set of equations which could predict the nitrogen and hydrogen pickup from various sources during ladle and casting operations. The comprehensive model is designed to predict the gas pickup under varying operating conditions such as the metal oxygen and sulfur content, the total tapping or stirring time, the stirring gas flow rate and the slag thickness. The model predictions are based on mathematical and empirical evidence which are derived from thermodynamic and kinetic fundamental principles.
