PROCEDURES AND SYSTEMS FOR ULTRASONIC GRAIN GRINDING AND DEGASSING DURING METAL CASTING USING ADVANCED VIBRATION COUPLING Russian patent published in 2022 - IPC C21B7/10 

FIELD: casting.

SUBSTANCE: invention relates to a device for ultrasound processing of molten metal in the production of cast metal billets with an adjustable grain size and products based on them. The device contains an oscillation source that is made with the possibility of transmission of energy to a receiver in contact with molten metal, wherein the specified oscillation source contains a probe located in a cooling channel, having at least one passage for introducing a cooling medium between the lower part of the probe and the receiver and made with the possibility of creation, during the operation, of oscillations and/or cavitations in the cooling medium directed to the receiver, while cavitations are directed through the cooling medium to the receiver.

EFFECT: reduction in the grain size is provided due to the creation of crystallization centers in molten metal for the formation of an equiaxial grain structure in the resulting cast metal billet without the use of chemical additives (TiBor), increase in the service life of band, in the result of which the performance is increased, increase in the cavitation due to the flow of the cooling medium out of a tip of the probe(s), as well as the possibility of change and/or improvement of thermodynamic characteristics of curing, which can potentially provide the synthesis of functionalized melts.
