The thermodynamics and kinetics module is part of the ferrous metallurgy course. This module explores the thermodynamics and kinetics behind the removal of carbon, oxygen, sulfur, hydrogen, nitrogen and phosphorus from steel, which are essential to the production of steels tailored to the demands of the consumer or specific applications.
Removal of Phosphorus, Hydrogen, and Nitrogen

Description
Dephosphorisation of steels has become a very important metallurgical technique in the steelmaking process to produce high quality steels. Steels having low content of P are necessary for applications where high ductility is needed, such as thin sheets, deep drawn steel, and pipelines etc. The effect of hydrogen and nitrogen are detrimental for final steel products. In this module the process of dephosphorisation will be explained. Then, the effect of hydrogen on the steel product will be treated. The mathematical explanation of kinetics of hydrogen removal will be introduced. Finally, the advantages of Nitrogen Removal and the effect of the argon flow rate increase will be described.
What you will learn
- Identify the effect of dephosphorisation;
- Explain the effects when hydrogen removal is applied;
- Identify the parameters that affect the nitrogen removal.
