Subject syllabus:

Lectures 1. Solutions – ideal, diluted solution – characteristics, importance. 2. Activities of components in solution – manners of expressing the activities, calculation of activities coefficients in poly-component systems. 3. Molten steelmaking slags, characteristics, formation of slags, theory of slags. 4. Nernst distribution law, desulphurisation of steel. 5. Reactions running at steel refining – transfer of oxygen from atmosphere into steel bath – mechanism. 6. Dephosphorisation of steel, phosphorus oxidation and stabilisation of P2O5 in slag. 7. Hydrogen and nitrogen in iron and steel – dependence of gas solubility on pressure, temperature and composition of steel. 8. Carbon reaction – its importance ate production and refining of steel, influence of temperature and pressure on development of carbon reaction. 9. Importance of deoxidation in steel, theoretical foundation of coagulating, diffusion deoxidation and deoxidation of steel by synthetic slag. 10. Conditions for formation of inclusions in liquid and in solidifying steel. Exercises 1. Heat capacities, enthalpy, entropy, Gibbs and Helmholtz energy. 2. Calculations of equilibria constants of reactions. Technical library - selection and processing of topical literary sources from the area of fundamentals of steelmaking. 3. Reaction isobar, reaction isotherm. 4. Raoult’s and Henry’s law. 5. Calculations of regular, athermal and real solution, test. 6. Calculation of active coefficients in poly-component systems, calculation of molecular and ion composition of slags. 7. Distributive equilibrium between slag and metal (phosphorus, sulphur), specification of program. 8. Reactions running at refining of steel (decarburisation, dephosphorisation, oxidation of silicon and manganese). 9. Deoxidation of steel, gases in steel. 10. Seminar - presentation of results of study of literature. Credit.
