Description
Short description:
Explore scientific principles and reaction mechanisms in deoxidation, decarburisation, and desulphurisation during steel refining.
Long description:
This advanced module investigates the scientific relationships that underpin secondary steelmaking operations. Building on previous content, it focuses on the thermodynamic behavior and reaction mechanisms of key refining stages: Deoxidation, Decarburisation, and Desulphurisation. Learners engage with rate equations, reaction constants, and equilibrium models to predict material behavior under industrial conditions. Real-world case studies and data visualizations support understanding of oxygen-carbon interaction, sulphur removal via synthetic slags, and the critical role of aluminium in controlling steel purity. The module culminates in interactive problem-solving exercises to strengthen analytical and predictive metallurgical skills.
What you will learn
- Apply rate equations and kinetic models to estimate time and efficiency in decarburisation processes.
- Interpret Al–O and C–O equilibrium diagrams to assess reaction progress and steel chemistry adjustments.
- Explain the scientific basis for slag-metal reactions in desulphurisation and their impact on steel purity.
- Evaluate how factors like pressure, temperature, and mixing intensity affect deoxidation performance.
- Solve quantitative problems involving carbon and sulphur levels using provided reaction formulas and empirical data.
