  • Method for melting aluminum scraps
    Patent number: 4159907
    Abstract: Economically advantageous melting of aluminum scraps is obtained by first compressing said aluminum scraps under a magnitude of pressure exceeding the yield strength of the material making up said scraps for thereby converting them into a compressed mass having an apparent specific gravity greater than the specific gravity of normal aluminum melt and subsequently introducing the compressed mass into a molten aluminum bath.
