ABSTRACT:
A method for continuous casting of light-alloy ingots, consisting in pouring a melt, acting upon the melt with ultrasound using at least one radiator to purify the melt and to refine the structure of the solidifying ingot, the radiation being applied uniformly throughout the cross-section of the melt in an intensity of 2 to 60 W/cm.sup.2 depending on the cross-sectional area of the solidifying ingot, the radiator being immersed into the melt to a depth equal to between 1/12 and 1/4 of the sound wavelength in the material of the melt and the melt temperature being maintained by 60.degree. to 150.degree. C. above the liquidus temperature of the melt, and subsequently withdrawing the ingot.
