The inclusions in Al-Si aluminum alloy was analyzed quantitatively and qualitatively by using filtration. The filtering time of Al-Si aluminum was tested by using IA-500 aluminum dross detector, the microstructure and inclusions composition was studied by using metallographic microscope and SEM, Image-Pro Plus was employed in this paper to analyze area ratio of inclusions. The results shows that 1935g alloy which used in the experiment was filtered out in 95 seconds. Black balls is mainly oxide, such as Al2O3, SiO2, MgO, gray strips is eutectic silicon. The area ratio of eutectic silicon is 8.22%, the area ratio of oxide is 0.8%. Source
