The influences of the low frequency
electromagnetic field on the horizontal direct chill casting process
were investigated experimentally. Ingots of 2024 aluminum alloy with
a cross size of 40~mm$\times$200~mm were produced by the
conventional horizontal chill casting process and low frequency
electromagnetic horizontal chill casting process，respectively. The
as-cast structures and the mechanical property of the ingots were
examined. The results showed that the low frequency electromagnetic
field could substantially refine the microstructures and
pronouncedly reduce the macrosegregation in the horizontal direct
chill casting process. Moreover, the surface quality of the ingot
was prominently improved by the low frequency electromagnetic field.
The fracture strength and elongation percentage of the ingot was
increased with the low frequency electromagnetic field.
