Effects of Low Frequency Electromagnetic Field on Cold-Shut Formation during Aluminium Alloy Hot-Top Casting

Abstract:

On the basis of conventional hot-top casting, low frequency electromagnetic field was applied in the process of hot-top casting to produce 7050 aluminum alloy ingot, the influences of low frequency electromagnetic field on cold-shut have been studied. The experimental results show that under the effect of the low frequency electromagnetic filed, the depth of cold folding has been decreased, and the as-cast structure has been refined. The reasons for low frequency electromagnetic field improving the surface quality, refining the structure of the ingot were summarized.
