Method for using a tubular sonotrode

Process for using a wetted tubular sonotrode. The process comprises the following steps: a) providing a tubular sonotrode (1) formed from a material that is substantially inert to liquid aluminium, such as a ceramic, for example a silicon oxynitride, the sonotrode comprising a first end region (2) t...

Zusammenfassung:	Process for using a wetted tubular sonotrode. The process comprises the following steps: a) providing a tubular sonotrode (1) formed from a material that is substantially inert to liquid aluminium, such as a ceramic, for example a silicon oxynitride, the sonotrode comprising a first end region (2) that is open and a second end region (3) that is preferably closed, b) at least partly immersing the open end region (2) of the tubular sonotrode (1) in the liquid aluminium alloy, and c) applying powerful ultrasonic waves to the liquid aluminium alloy by means of the tubular sonotrode (1).
