Изобретение относится к области металлургии, в частности, к обработке расплавов упругими колебаниями, например, ультразвуковыми и может быть использовано при рафинирующих переплавах. Техническим результатом изобретения является повышение физической однородности чистого металла путем устранения полигонизационных границ в чистых металлах с сохранением исходной чистоты или предотврращения их образования. Способ включает расплавление металла, его кристаллизацию и ультразвуковую обработку, которую ведут с возбуждением знакопеременных напряжений не менее предела текучести обрабатываемого материала при температуре кристаллизации. Ультразвуковую обработку можно проводить как при кристаллизации слитка, так и после окончания кристаллизации слитка в процессе его охлаждения.The invention relates to the field of metallurgy, in particular, to the processing of melts by elastic vibrations, for example, ultrasonic and can be used for refining melts. The technical result of the invention is to increase the physical homogeneity of pure metal by eliminating the polygonization boundaries in pure metals while maintaining the original purity or preventing their formation. The method includes melting the metal, its crystallization and ultrasonic treatment, which is carried out with the excitation of alternating stresses not less than the yield strength of the processed material at crystallization temperature. Ultrasonic processing can be carried out both during crystallization of the ingot, and after crystallization of the ingot during its cooling.
