Opis:
The results of the thermal reclamation investigations of the spent moulding sand with the polymer BioCo2 binder, are presented in the paper. The reclamation process of the quartz matrix was carried out on the basis of the author's own method of selecting the reclamation temperature. On the bases of the performed thermo-gravimetric analysis of the binder the temperature range required for the efficient thermal reclamation was indicated. In order to confirm the assumption the thermal reclamations were performed at a temperature determined by the TG and - for comparisons - at a lower and higher temperature. During the reclamation process samples of the reclaim were taken for testing ignition losses in order to determine the process efficiency. The correctness of the assumed method of selecting the temperature range of the thermal reclamation of spent moulding sand with the polymer BioCo2 binder was confirmed.

Opis:
The investigation results of the thermal reclamation of spent core sands made in the hot-box technology are presented in the paper. Energy-consumption of the process was tested by recording the media consumption during the thermal treatment of the determined intensity. Gas demands in dependence of the reclamation process temperatures were compared. During the reclamation process the reclaimed material samples were taken to test ignition losses in order to determine the efficiency of the realised procedures. The influence of the reclamation temperature on the quality of the obtained reclaimed material was checked. The effects of the realised reclamation procedures of the same moulding sand at various temperatures were also assessed on the grounds of strength of moulding sands prepared on the bases of the obtained reclaims. It was found that the process energy-consumption can depend on the expected core sand parameters. The attention was drawn to the fact, that bearing of costs for the thermal reclamation - very often - does not correspond directly with the obtained effects. The thermal reclamation performed very intensively, which corresponds with the costs increase, is not always needed for obtaining the core sand of parameters comparable with the sand made of fresh components.

Opis:
W publikacji przedstawiono wyniki badań, których celem było określenie wpływu wybranych parametrów pracy doświadczalnego regeneratora termicznego na skuteczność jego działania. Efektywność pracy urządzenia przeprowadzono analizując wpływ: temperatury pracy, temperatury powietrza fluidyzacji, stopnia nagrzania komory regeneratora termicznego oraz sposobu mieszania złoża. Badania wykonano na stanowisku doświadczalnym zainstalowanym w hali maszyn odlewniczych Wydziału Odlewnictwa AGH. Ocenę wpływu poszczególnych parametrów dokonano na podstawie badania strat prażenia pozyskanego regeneratu. Wykonano także badania wytrzymałości na zginanie kształtek z masy rdzeniowej w uniwersalnej maszynie do wykonywania próbek testowych i małych rdzeni w technologii hot-box (LUT).
The publication presents the results of a study aimed at determining the effect of selected parameters of the experimental thermal regenerator on its effectiveness. Efficiency of operation was carried out by analysing the effect of: operating temperature, fluidizing air temperature, heat degree in regenerator chamber and method of mixing fluidized bed. The research was conducted at the experimental station installed in the machine hall of the Faculty of Foundry Engineering AGH UST. Assessment of the impact of individual parameters was based on loss on ignition of achieved reclaims. Studies of bending strength of the core sands prepared with reclaim in hot-box technology are also presented.

Opis:
The investigation results of the influence of the selected parameters of the thermal reclaimer operations on the temperature changes in the combustion chamber and the process energy consumption, are presented in the hereby paper. The analysis of the heat treatment was performed with the application of a fresh foundry sand, since it was assumed that the dominating energy part was used for the grain matrix heating and due to that, the energy used for burning small amounts of organic binder remained on sand grains could be omitted. Thermal treatment processes performed under various conditions were analysed from the point of view of a gas consumption and temperatures obtained in the experimental reclaimer. The recorded data allowed to point out the parameters having essential influence on the process of the quartz matrix heating in the combustion chamber as a gas consumption function.
