Furnaces for heat treatment of metals
Pražan, Jan ; Myška, Martin (referee) ; Záděra, Antonín (advisor)
The bachelor thesis focuses on construction of furnaces for heat treatment of metal. The classification and description of heat treatment of steel, cast iron, non-iron metal and their alloys was based on literature review. The description of the key ways of temperature transfer is provided: by conduction, convection, and radiation. The furnace type’s distinction was created according to the types of construction, heat treatment, and its purpose. The main focus was on chamber furnaces construction and their use. In addition the performance calculation, insulation types overview, ways of heating, temperature distribution, and also heat measurement, and regulation needed for treatment are presented. The thesis provides also assessment of advantages and disadvantages of insulation types and selected ways of heating (i.e. flame and resistance heat sources).

Heat processing principle of operation thermal resistance annealing.
Špičková, Petra ; Humár, Anton (referee) ; Kalivoda, Milan (advisor)
The project assigned for the bachelors study program B 2307 analyses the theory of heat processing in general and furthermore resistance annealing with the focus on the technology developed by the company Heatmasters. Examples of processing methods used at other technology providers are presented, inclu-ding documentation and datasheets. Resistance annealing is based on the heat transfer from a resistive wire, which heats up by electrical current. The thermal energy is then transferred to the target material through heat radiation or con-ductance. The resistance heat processing is used both for welding and for an-nealing. Nowadays is the documentation and recording of the heat processing of significant importance. Possibilities exist that allow recording of temperature during the entire cycle of the heat processing and subsequently providing the result evidence in a form of a certificate.
