Summary

The subject is focused on understanding the findings from the field of theory and technology of iron production. Attention is paid to batch materials, technological principles of production and basic processes taking place during iron production. Further the subject is focused on theoretical knowledge of processes taking place during steel production, technological principles of production in the primary steelmaking aggregates, manners of steel dezoxidation and alloying, secondary metallurgy and steel casting.
