In 2014 we finished research works involved in the development of a technology for manufacturing innovative ceramic-carbon foam filters for molten metal alloys filtration, which were financed by the National Centre for Research and Development (NCBiR) from INNOTECH programme resources. A batch of the filters produced in this technology was tested in practice in domestic cast steel and cast iron foundries. The trials were successful and foundries declared their intention to purchase the newly-developed filters for the current production of casts. This provided an incentive for “Ferro-Term” Sp. z o.o. to start design works on the prototype line for a serial production of these filters. At the same time, in co-operation with a scientific consortium, including the co-authors of the technology, i.e. the Institute of Ceramics and Building Materials, Refractory Materials Division in Gliwice, Institute for the Chemical Processing of Coal in Zabrze and Foundry Research Institute in Cracow, the company made a successful attempt to raise some funds for the necessary adaptation of the developed technology from the semi-technical to industrial scale from Intelligent Development Operational Programme. In the article we have presented information on the effects of works performed within the framework of the project entitled “Modernization and adaptation of the existing technological line for purposes related to technology verification and start-up of the production of innovative ceramic-carbon filters for molten metal alloy filtration”.

Possibilities of pumping molten metals and salts (as cooling agents in nuclear reactors) by magnetohydrodynamic (MHD) pumps with permanent magnets are investigated. The principal attention is paid to the steady-state movement of these quenchants in the closed cooling loops described by the balance of the Lorentz force produced by the pump and hydrodynamic drag forces. The methodology is illustrated on two typical examples whose results are discussed.

W artykule przedstawiono wyniki badań nad możliwością zastosowania pomp magnetohydrodynamicznych (MHD). Najwięcej uwagi poświęcono analizie stanu ustalonego ruchu medium chłodzącego w obiegach zamkniętych pod wpływem siły Lorentza generowanej przez pompę i sił oporu hydrodynamicznego. Metodykę badań zilustrowano dwoma typowymi przykładami, dla których przeprowadzono analizę wyników symulacji.
