DEVICE FOR ULTRASONIC TREATMENT OF MELT OF LIGHT ALLOYS Russian patent published in 2020 - IPC C22B9/02 C22F3/02 C22C1/06 

FIELD: metallurgy.

SUBSTANCE: invention relates to non-ferrous metallurgy and can be used in production of light alloy ingots, shaped casting and disperse hardening of aluminum alloys by adding micro- or nanoparticles into the material. Device for ultrasonic treatment of melt of light alloys consists of piezoelectric transducer, concentrator, emitter of niobium, tantalum or their alloys with length of not less than length of wave longitudinal oscillations of ultrasound at excitation frequency, wherein at concentrator in place of minimum mechanical vibrations there is a fastening band symmetrical to concentrator axis and radiator there is cooling chamber made in form of hollow cylinder with coolant inlet and outlet pipes, one of cooling chamber end surfaces is tightly fixed on concentrator belt, and the second end surface of the cooling chamber has a central hole and is tightly fixed on the surface of the radiator in a location located at a distance equal to a quarter of the oscillation wavelength in the radiator from the point of connection of the radiator to the concentrator.

EFFECT: ruling out concentrator-emitter acoustic contact disturbance, higher stability of oscillatory system parameters during melt treatment.
