Description
Short description:
Refining: Control phosphorus, hydrogen, and nitrogen removal using gas kinetics and slag-metal strategies in steelmaking.
Long description:
This module explores advanced refining techniques for the removal of phosphorus, hydrogen, and nitrogen in molten steel. Learners will investigate how these elements affect steel quality, assess kinetic and thermodynamic principles governing their removal, and compare degassing strategies under varying process pressures. Emphasis is placed on the evaluation of slag-metal interactions, gas solubility, and diffusion kinetics. Case-based applications and interactive content guide learners in optimizing refining practices to meet strict metallurgical specifications.
What you will learn
- Explain the impact of phosphorus, hydrogen, and nitrogen on steel quality.
- Evaluate dephosphorisation mechanisms based on slag-metal interactions.
- Analyze hydrogen removal kinetics in modern degassing systems.
- Assess nitrogen removal strategies using thermodynamic and kinetic principles.
- Compare gas solubility and pressure influence on refining reactions.
- Apply refining techniques to meet specification limits for non-metallic impurities.
