摘要: The invention relates to a method and apparatus for obtaining an ingot wherein elastic oscillations are directed on metal being crystallized over a broad frequency range and at high intensity in the form of powerful pulses generated by a high-voltage spark discharge in liquid. One form of the apparatus of the invention comprises a discharge chamber filled with liquid in contact with a mould or with melt. The discharge chamber is provided with a system of electrodes connected to a pulse current generator. Upon feeding high-voltage current pulses to the electrodes, high pressure, impulse flows, cavitation and surge waves are built-up in the liquid resulting in the appearance of elastic oscillations acting on the molten metal.
