Claims

1. APPARATUS FOR TREATING A SOLIDIFYING MASS OF MOLTEN METAL, SAID APPARATUS COMPRISING IN COMBINATION A PLURALITY OF INDEPENDENTLY-OPERABLE EXTERNAL AGITATORS INCLUDING BOTH ELECTRO-MAGNETS AND VIBRATORY ELECTROMECHANICAL TRANSDUCERS DISPOSED OUTSIDE SAID MASS OF MOLTEN METAL AND SPACED AROUND AND SUBSTANTIALLY ADJACENT TO THE FREEZING ZONE OF THE METAL, SAID AGITATORS PRODUCING WHEN ENERGIZED A PLURALITY OF AGITATING FORCE FIELDS FOCUSED WITHIN SAID MASS, AN AGITATOR-ENERGIZING SOURCE CONNECTED WITH SAID AGITATORS, SAID SOURCE SELECTIVELY ENERGIZING SAID AGITATORS NONUNIFORMLY, SO THAT THE MOTLEN METAL IN THE FREEZING ZONE IS AGITATED BY THE AGITATING FORCE FIELDS TO CONTROL PROPERTIES OF THE RESULTANT SOLID METAL.
