In order to achieve adequate melt quality for casting, it is important to clean the melts from inclusions, for which there are numerous methods that can be used. In the course of the presented research, the inclusion removal efficiency of rotary degassing coupled with the addition of different fluxes was investigated. The effects of various cleaning fluxes on the inclusion content and the susceptibility to pore formation were compared by the investigation of K-mold samples and the evaluation of Density Index values at different stages of melt preparation. The chemical composition of the applied fluxes was characterized by X-ray powder diffraction, while the melting temperature of the fluxes was evaluated by derivatographic measurements. It was found that only the solute hydrogen content of the liquid metal could be significantly reduced during the melt treatments, however, better inclusion removal efficiency could be achieved with fluxes that have a low melting temperature.}, type={Article}, title={The Comparative Analysis of the Inclusion Removal Efficiency of Different Fluxes}, URL={http://www.czasopisma.pan.pl/Content/114697/PDF/AFE%202_2020_09.pdf}, doi={10.24425/afe.2020.131302}, keywords={Castings defects, Aluminum alloy, Inclusions, Cleaning flux, Melt treatment}, }
