| Abstract Scope |
This study explores the impact of melt conditioning and filtration on the quality of ingots made of recycled aluminum alloys, particularly for automotive body sheet applications. Recycled aluminum alloys often suffer from inclusions and inconsistent properties due to prior usage and contamination. By employing melt conditioning, we aim to improve the homogeneity and refine the grain structure, while filtration is used to remove non-metallic inclusions. We investigated the effects of rotor shape, location, and degassing conditions in rotary degassing equipment, as well as the type of ceramic foam filter. The quality of the aluminum melt was assessed using the density index (DI) from vacuum solidification tests, with microstructural and mechanical properties evaluated through optical microscopy (OM), scanning electron microscopy (SEM), and universal testing machine (UTM) analysis. Our findings provide insights into the mechanisms behind these improvements, advancing the efficiency and reliability of recycled aluminum alloy processing. |
