Production and properties of advanced Cu-based alloys castings
Kryštůfek, Tomáš ; Pernica, Vítězslav (referee) ; Kaňa, Václav (advisor)
This bachelor thesis is focused on well-arranged processing of production copper alloy castings. Following a brief historical introduction, a process of producing crude copper is first developed. Attention is paid to the sources of copper in nature and the subsequent melting of copper in furnace and converter. Furthermore, the technology of melting copper alloys is elaborated meaning melting devices, melting gases, melting directions and deoxidation. Very high purity copper can be produced by refining the crude copper in an electrolyte or by electroslag remelting and melted according to three technological processes. There are finally elaborated the processes of melting, properties and use of bronze and brass in detail - foundry copper alloys.
