Content
|
The course provides theoretical and practical knowledge in the field of steel and cast iron production in electric arc and induction furnaces and cupolas. Attention is also paid to modern trends in steel and cast iron metallurgy, which increase the purity of melts and thus the mechanical properties of castings.
Overview of lecture topics:
1.Solutions of molten metals, applications in metallurgy.
2.Interaction of gases with solid and molten metal, molten slag.
3. Production of steels in basic EOP, oxidation period of melting, reaction of oxidation period, dephosphorization.
4.Refining of steel on secondary metallurgy equipment (LF, VD / VOD, AOD ...).
5. Continuous steel casting.
6. Casting of ingots and castings.
7. Electroslag remelting (ESR) and vacuum arc remelting (VAR).
8. Melting of cast irons.
9.Metallurgical reactions in the production of cast irons.
10. Vaccination and modification of cast irons.
11.Metallurgy of non-ferrous metals.
12.Quality control in metallurgical production.
13. Defects caused by incorrect metallurgy.
