Summary

1) First part of subject is read with aim to outline study of basic relations and structures of metallurgy aggregates in metallurgy original production area. In harmony with actual tendency attention is paid also to automatic equipment, ecology problems and alternative methods of hot metal production. 2) the second part of subject is read with aim to know steelmaking problems. Survey and development of metallurgy processes, steelmaking slags, oxidisation processes, steel de-O, steelmaking in converters, tandem and electric furnaces, secondary metallurgy of steel, casting, solidification and crystallization of steel.
