Influence of a low-frequency electromagnetic field on aluminum alloy slabs during horizontal direct chill casting process

Résumé

2024 aluminum alloy slabs were horizontally cast under low-frequency electromagnetic fields. The results showed that when the frequency of the magnetic field is kept at 30 Hz, the α-Al grain size becomes smaller with increase of the intensity of magnetic field, indicating that high intensity of the magnetic field is beneficial to the grain refinement. When the intensity of magnetic field is kept at 15000 At, 30 Hz is confirmed as the favorable frequency for obtaining fine α-Al grains. Furthermore, high intensity and relatively low frequency are more effective to inhibit the gravity segregation of Cu element.
