Application of secondary metallurgy during steel manufacture
Škeřík, Filip ; Fila, Pavel (referee) ; Záděra, Antonín (advisor)
This bachelor thesis is a literary research on the use of secondary metallurgy in steel manufacture. It contains the basic division of SM and a brief description and use of individual processes. The main part is focused on the description of the structural parts of the electric arc furnace, ladle furnace and VD/VOD device. The second part of the thesis is devoted to an experiment, where the technical- economic costs of production of low and medium alloyed steels and high alloyed steels are compared. It includes costs on charging, electricity consumption, graphite electrode consumption and furnace and cover lining.

History of ferrous alloys manufacture in the Foundry of ŽĎAS, a. s.
Nejedlý, Tomáš ; Pernica, Vítězslav (referee) ; Šenberger, Jaroslav (advisor)
The thesis describes the history of modern age of steel production in Ţďár region, and the history of metallurgical engineering company ŢĎAS. The work is divided into the theoretical part of the steel production on electric arc furnaces along with brief history from steel production in bloomery furnace to the modern steel manufacturing technology - secondary metallurgy. The second part describes the history of steel production in Ţďár region until the formation of metallurgical engineering company ŢĎAS, and consequently the company development from the construction to the present day. The thesis are focused on the development of secondary metallurgy by which the ŢĎAS company can reach the steel with high level of micro cleanness and high level of mechanical properties. Using by this technology the company can extend its product range by introducing new steel grades. Thanks to the continuous progress and efforts to achieve the best results in steel quality, the ŢĎAS company be among the largest producer of quality steel not only in the Czech Republic.
