ABSTRACT:
A metallic product is cast continuously by injecting a liquid metal into a cooled ingot mold, applying a magnetic field turning about the axis of the mold to rotate the metal, and extracting the partially solidified metal product from the mold. Effective stirring is obtained by rotating the magnetic field at a frequency of rotation of 4 to 15 Hertz and using a copper alloy of structural rigidity for the mold, the wall thickness of the mold being kept thin, preferably below 15 mm. The process is particularly useful for casting round metallic products and especially those which are subjected to after-treatments requiring good surface characteristics and a core free of faults.
