Claims10
An apparatus for producing semi-solidified metal compositions through electromagnetic agitation, comprising a cooling agitation tank provided with means for cooling molten metal, an electromagnetic induction coil producing a rotating magnetic field across a section of the tank to rotate molten metal in the tank, and a non-magnetic and non-conductive core member positioned in a central portion of the tank.
Apparatus for producing semi-solidified metal compositions by electromagnetic agitation comprising:
- a cooling agitation tank provided with means for cooling molten metal;
- an electromagnetic induction coil producing a rotating magnetic field across a section of the tank to rotate molten metal in the tank;
- and
- a non-magnetic and non-conductive elongated core member positioned in a central portion of the tank and within a central portion of the rotating magnetic field.
Apparatus for producing semi-solidified metal compositions by electromagnetic agitation comprising:
- a tank provided with means for cooling molten metal;
- electromagnetic induction means for producing a rotating magnetic field within at least a portion of the tank to rotate at least a portion of molten metal in the tank;
- and
- a non-magnetic and non-conductive core member positioned within the tank and rotating magnetic field.
