Abstract

The invention relates to a process for refining the microstructure of metals and alloys cast by the "HOT TOP" technique by inducing cavitation through electromagnetic or mechanical vibration within a magnetohydrodynamic or Helmholtz resonator in combination with gentle stirring of the molten metal. For carrying out this method, a device is used having an input hopper 18 for the molten metal, an upper ceramic ingot mold for containing the molten metal, a water tank for water cooling the solidifying metal, a means for agitating the molten metal, such as an alternating electromagnetic pump, a resonant cavity in which to induce the cavitation phenomenon, a fixed magnetic field, and an inductor coil for producing a gentle stirring along flow path.
