Archives of Foundry Engineering continues the publishing activity started by Foundry Commission of the Polish Academy of Sciences (PAN) in Katowice in 1978. The initiator of it was the first Chairman Professor Dr Eng. Wacław Sakwa – Corresponding Member of PAN, Honorary Doctor of Czestochowa University of Technology and Silesian University of Technology. This periodical first name was „Solidification of Metals and Alloys” , and made possible to publish the results of works achieved in the field of the Basic Problems Research Cooperation. The subject of publications was related to the title of the periodical and concerned widely understand problems of metals and alloys crystallization in a casting mold. In 1978-2000 the 44 issues have been published. Since 2001 the Foundry Commission has had patronage of the annually published “Archives of Foundry” and since 2007 quarterly published “Archives of Foundry Engineering”. Thematic scope includes scientific issues of foundry industry:
- Theoretical Aspects of Casting Processes,
- Innovative Foundry Technologies and Materials,
- Foundry Processes Computer Aiding,
- Mechanization, Automation and Robotics in Foundry,
- Transport Systems in Foundry,
- Castings Quality Management,
- Environmental Protection.
Extremely intense development of civilization requires from foundry casting technologies very high quality and not expensive castings. In
the foundries, there are many treatments that allow increasing of the final properties of produced castings such as refining, modification,
heat treatment, etc. One of the methods of increasing the quality of the casting by removing inclusions from the liquid alloy is filtration.
The use of ceramic-carbon foam filters in filtration process is still analysed phenomenon that allows improving the final properties of
castings. A modern method of research, testing and synthesis of innovative chemical compositions allows improving the properties of such
filters. In the paper the evaluation of application properties of developed ceramic-carbon bonded foam filters is presented. The quality of
the foam filters is evaluated by Computer Tomography and foundry trials in pouring of liquid metal in test molds. Additionally computer
simulations were made to visualize the flow characteristics in the foam filter. The analysed filters are the result of the research work of
Foundry Research Institute and the Institute of Ceramics and Building Materials, Refractory Materials Department in Gliwice.
