Quality control of the iron castings in the foundry
Krvač, Matěj ; Kaňa, Václav (referee) ; Záděra, Antonín (advisor)
This bachelor thesis deals with the properties of castings with ductile iron and gray iron. The theoretical part was focused on knowledge related to chemical composition, mechanical properties and monitoring of internal defects. In the experimental part, the structure is evaluated in non-etched and etched state. It compares with the chemical component and the mechanical properties with the literature. X-ray frames are monitored for internal defects. In conclusion, the results of the experiments are summarized and measures are proposed to improve the casting quality.
Influence of the mixing plant manufacturing temperatures on the properties of aggregates
Brtníková, Tereza ; Stehlík, Dušan (referee) ; Hýzl, Petr (advisor)
The bachelor thesis describes the production process of aggregate and production process of asphalt mixing in batch asphalt mixing plant. There is also mentioned the test procedure of endurance against grind and against freezing and defrosting. The tests were did on 3 types of rocks, which have been burdened by temperature on 110 °C, 200 °C and 300 °C. Then were the results compared.
