Thermoproperties of foundry moulds in dependence on different used foundry sands
Šuráň, Jiří ; Rusín, Karel (referee) ; Cupák, Petr (advisor)
The project elaborated in frame of engineering studies is submitting the study of thermal properties of holding mixtures using different types of sand. Were tested a total of 5 sands: zirkon, ŠH22, chromite, olivine and dunite. Molding compounds were tested for thermal capacity, thermal conductivity and heat accumulation. The highest heat capacity was achieved in dunite sand. The largest heat accumulation had mixture with chromite sand and the best thermal conductivity was found in a mixture with olivine sand.

Manufacturing possibilities of wire holder
Šuráň, Jiří ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
The project solved in the framework od Bachelors studies presents a proposal of the manifacturing possibilities of wire holder – piece of steel sheet 12 020.20. Holder is product of Spálovský company. The estimated series production is 1 000 000 pieces a year. At the base of literatural studies of technology of forming and technology of founding was selected and described 5 manufacturing possibilities of wire holder. Every posibility was evaluated in consideration of series production of the holder. For 2 the best possibilities was worked up the procedure list of manufacturing.
