Lectures
1. Equilibria. Equilibrium constant and manners of its expression. Principle of action and reaction.
2. Criteria of processes equilibria (G, K). Reaction isotherm and its importance.
3. Ideal solution – Raoult’s law. Diluted solution – Henry’s law.
4. Thermodynamic activity of a component in solution. Manners of expressing activity of component in solution.
5. Calculation of activity coefficients in poly-component systems. Molten steelmaking slags – molecular theory of slags.
6. Ion theory of slags. Affinity of elements – especially to oxygen.
7. Nernst distribution law. Distribution of oxygen between slag and metal.
8. Reactions running at production and refining of steel: oxidation of Si and Mn, transfer of oxygen from atmosphere into steel bath. Dephosphorisation of steel.
9. Desulphurisation of steel. Solubility of gases in metals; dependence on partial pressure of gas and on temperature.
10. Hydrogen in iron and steel. Nitrogen in iron and steel.
11. Oxygen in iron and steel. Carbon reaction and its importance at production and refining of steel.
12. Influence of temperature and pressure of development of carbon reaction. Vacuum carbon deoxidation of steel.
13. Coagulating deoxidation of steel. Diffusion deoxidation and deoxidation of steel by synthetic slags.
