Model study on in-situ detection of inclusion in liquid metal by ultrasonic waves
Journal Title: Science Paper Online - Year 2008, Vol 3, Issue 11
Abstract
The possibility of using ultrasonic waves to in-situ detect the inclusions in liquid metals is researched by a water model. The effects of inclusions with different properties on ultrasonic waves propagating through water are examined and compared. It is found that the intensity of ultrasonic waves decreased and the wave pattern also changed obviously when there were inclusions in the solution. Furthermore, the changes mentioned above for different inclusions were not similar. The influences of concentrations and particle sizes of inclusions on the diffusing of waves are also studied. The detected pressure of the ultrasonic waves became smaller with the increasing of the inclusion concentration and particle sizes，and the fluctuations of the waves were sensitive to the changes of the above two factors. From the experiment results, it can be concluded that acoustic waves can be used to detect the inclusions in liquid metal directly.
