Analýza výroby odlitků ze slitin hliníku odlévaných do kokil
Dočekal, Jan
The diploma thesis is divided into two parts - theoretical and experimental. The theoret-ical part deals with machining of foundry as a production technology, where emphasis is placed on gravity casting. Further the theoretical part deals with the problems of the thermal regime of mold, dimensional stability and defects of castings, where this issue is important for experimental measurement in the foundry and its evaluation. The experimental part transmits the findings from the theoretical part to reality by measuring castings. Here is a description of the measured castings and the main parts of the temperature and casting temperature measurements, casting dimensions measure-ments. It follows the evaluation of casting defects. At the end of the work is discussed the measured results with their possible causes and suggestions for further solution.

The main objective of this thesis is to assess the suitability of multilayer wood flooring especially in terms of dimensional stability, which is the most important feature when combining flooring with underfloor heating. Part of the work is to describe the problems of floor heating from the perspective of the past and present point of view, mention types of flooring, including designs and flooring installations. The second part of the work is about issue of step layer suitable for underfloor heating, with a broader focus on wood materials, particularly engineered wood flooring. Work also includes measured values and processed to assess two three-layer flooring of different material composition. In conclusion of this work is indicated an assessment of available laminated wood flooring, which were examined in our test and also draft of new design flooring made of wood, which would improve the thermal effects of underfloor heating.
