“…The study is a part of a research project that deals with the refining technologies research and development, the purpose of which is to increase the quality of aluminum alloys intended for heavy duty castings, manufactured by the MOTOR JIKOV Slévárna a.s. die casting foundry. The project subject is development and innovation of production technology and aluminum alloys refinement [14,15]. The aluminum melt refinement is realized through two FDU devices for high-pressure and low-pressure casting.…”

This paper deals with approximate physical modelling of aluminum melt degassing, performed under lowpressure die casting conditions of aluminum castings. The modelling took place on an aquatic physical model on a 1:1 scale to the operating conditions, constructed in the laboratories of ITB in ČB. Tested parameters were defined based on operating conditions (rotation speed and inert gas flow). Various combinations of these parameters created 20 tested variants, including the current set of parameters used in operating conditions. The effects of the tested parameters were determined using the results of measurement. Increasing the rotation speed and the inert gas flow accelerates gas removal from the model liquid. It will be possible to further use this knowledge in refining technology optimization in the low-pressure aluminum die casting.
