Paper Title:
Study on Characteristics of Ultrasonic Fields by Hydraulic Model of Ladle Refining
  Abstract

Under ultrasonic irradiation at a frequency of 20 kHz, hydraulic model experiments have been performed to improve the stirring effect in the ladle refining. The cavitation intensity and ultrasonic field distribution were measured by dyeing method. The dynamic behavior of acoustic cavitation bubbles were visualized with a high-speed digital camera. The results show that: the mixing time under ultrasonic can be reduced obviously, and the dynamic conditions can be improved apparently;stable and complete patterns can be got by dyeing method, then relative intensity and the position of antinode and node can be determined from the pattern; the distribution of ultrasonic fields at tool end is circular cone; the cavitation bubbles were confirmed to be generated around the antinode of sound pressure during the ultrasonic stiring and moved linearly in random directions.
