Numerical simulation of mechanical properties of cast irons
Haluza, Jakub ; Bouška, Ondřej (referee) ; Krutiš, Vladimír (advisor)
Diploma thesis in the first part deals with the production, properties and application of compacted graphite iron. After then calculation model which is used in ProCAST software for the predicting mechanical and structural properties of compacted graphite iron is presented and differences between versions 2010 and 2011 are shown. The last part of the thesis deals with simulation of mechanical and structural properties on the test specimen and real casting, which is poured in Heunisch foundry Ltd. and results of the simulation and measured values are compared.

Desulphurization of pulverized coal bouler (dry bottom ash) in Teplarna Olomouc
Haluza, Jakub ; Lisý, Martin (referee) ; Skála, Zdeněk (advisor)
This master thesis deals with the feasibility studies desulphurization of powder granulation K3 boiler at Olomouc heating station. K3 boiler burns black energetic coal and after January 1st, 2016 will not meet new more strict emission limits. The theoretical part of the thesis charts usable desulphurization methods from which the semi-dry NID appears as the most appropriate one. In the practical part there is performed a stoichiometric calculation of the flue gas and the balance of raw materials and output products. The possibility of NID method usage is confirmed here. Next the annual operating cost of the desulfurization process is calculated and some NID systems already installed references are presented.

Manufacture and properties of high-alloyed Cr steels
Invald, David ; Haluza, Jakub (referee) ; Záděra, Antonín (advisor)
The bachelor thesis deals with the issue of properties, production, distribution, and use of high-alloyed chromium steels. One of the main part of the thesis is devoted to corrosion because corrosion resistence is important properties of high-alloyed chromium steel. The last part deals with high-alloy steels production and equipment for steel production.

Developments in numerical simulation of foundry processes
Haluza, Jakub ; Kováč, Marek (referee) ; Krutiš, Vladimír (advisor)
With the development of the computer equipment the numerical simulation has become a strong tool for the design and optimization of foundry processes. The goal of the modelling is the tuning of the casting technology in pre-manufacturing stage. Numercial simulation allows studying metal flow, solidification and casting cooling. The work will be aimed to new trends and developments in the field of numerical simulation of foundry processes.

Manufacturing of castings of a frame of Praga 500 BD motocycle
Vraspír, Kamil ; Haluza, Jakub (referee) ; Roučka, Jaromír (advisor)
The bachelor degree thesis deals with the complete production technology of replica castings of motorcycle frame Praga 500 BD. In the first part of paper is described the historical development of fabric Praga – BD and technical parameters of motorcycle. In the second part is exactly described the production process of model device, comparison of material variants for model producing, forming and preparing metal including casting. Finally the heat treatment and machining castings are described there. The result of work is fabrication of working replica castings of motorcycle frame.
