Properties and micropurity of steels produced using vacuum metallurgy
Krontorád, Jakub ; Pernica, Vítězslav (referee) ; Záděra, Antonín (advisor)
This master thesis contains analysis of metallurgical quality of medium alloyed steel from the perspective of microcleanliness and content of dissolved gases. Apart from thorough research there are result of three melts from vacuum induction furnace (VCAP-Consarc), from which, conclusions are made. Each of the scrap material types (steel scrap, VD scrap and ESR scrap) had different metallurgical quality and initial microcleanliness, which influenced the final quality of the ingot. Lastly both degassing process and the thermodynamical probability of the reaction of silicon-oxide based sampling pipe with melt has been examined and calculated.

System control and protection turbo generators
Veverka, Marek ; Panáč, Martin (referee) ; Matoušek, Antonín (advisor)
The topic of this thesis is description, analysis and proposal of turbo generator’s control and protection system. The power output of turbo generators is from 3 MVA up to 75 MVA for various industrial sectors. The final proposal is based on the results of this analysis and it consists of a modern control and protection turbo generators systems. This proposal is designed to respect universality, customer’s requirements. And this proposal should be used in many industry branches.

Secondary metallurgy in foundries
Klika, Jiří ; Šenberger, Jaroslav (referee) ; Pernica, Vítězslav (advisor)
The aim of this bachelor thesis is to write a literary research about various methods of secondary metallurgy. In the thesis is described principle of methods and its advantages and disadvantages after installation in the manufactory, especially principle of steelmaking methods. It mainly concerns advantages of secondary metallurgy as degassing, decarburisation, desulphurisation and chemical or heat homogenization of liquid metal in the ladle.

Metallurgy along the East Aegean-West Anatolian Interface in the Second Millennium B.C.
Roháček, Miloš ; Pavúk, Peter (advisor) ; Bouzek, Jan (referee)
(in English): This thesis aims at collecting, cataloguing and analysing bronze objects from the area of the East Aegean-West Anatolian Interface in the second millennium B.C. Based on closer typological assessment and comparanda, the question of eventual local specific production along the Interface, different from the Aegea or Eastern Mediterranean, is being investigated here. From up to 217 collected items, indeed many types of bronzes, especially swords, razors and spearheads indeed show a set of specific features. Also, the characteristic of bronze metals differs in Lower Interface with stronger minoan-mycenaen influnce from items in Upper Interface which seems to be following more anatolian features.
