The effect of cavitation and sound flow produced by ultrasound in high temperature melt is utilized to achieve grain refinement. Previous papers mainly discussed the cavitation mechanism of the end face of the ultrasonic radiation rod, but did not pay enough attention to the cavitation effect on the side face of the radiation rod. Therefore, this paper studied the cavitation range of the side of the ultrasonic radiation rod. Firstly, the amplitude of the side of the ultrasonic radiation rod was measured. It was found that the amplitude of the side varied greatly with the location. Secondly, the simulation results showed that the vibration of the side of the radiation rod changed alternately with periodic peaks and troughs. Thirdly, the ultrasonic experiment of pure aluminum was carried out in crucible. Two titanium plates were cut into a suitable shape and placed in crucible. After 13.5 hours of ultrasonic treatment, it was found that the surface of titanium plates was not uniformly eroded, but the most serious cavitation erosion occurred in the middle position. Therefore, it can be explained that the cavitation effect occurred in this region. At the same time, the macrostructure of aluminium ingot treated by ultrasound was obviously refined.
