FIELD: metallurgy.
SUBSTANCE: invention relates to methods of ultrasonic treatment of liquid aluminium alloys. Method comprises the following steps: providing tubular sonotrode (1) formed from a material substantially inert to liquid aluminium, such as ceramics, wherein sonotrode comprises a first end area (2) which is open, and a second end region (3), which is preferably closed, immersing at least part of open (2) end area of tubular sonotrode (1) into liquid aluminium alloy and exposure to liquid aluminium alloy by powerful ultrasonic waves by means of tubular sonotrode (1).
EFFECT: technical result of claimed invention is optimization of cavitation process in liquid aluminium alloy, which enables to handle large volumes of liquid aluminium alloy on industrial scale.
