ULTRASONIC WAVE GENERATING DEVICE FOR CONTROLLING SOLIDIFICATION STRUCTURE

摘要

There is provided an ultrasonic wave generating device for controlling solidification structure, which is able to prevent some of ultrasonic waves from leaking out by the reflection of the ultrasonic waves on an incidence interface in a transfer process of transferring high-intensity ultrasonic waves generated in an ultrasonic wave transducer to the inside of molten metal. The ultrasonic wave generating device for controlling solidification structure comprises an ultrasonic wave transducer generating ultrasonic waves and applying the generated ultrasonic waves to an inner part of a cast; and a reflective plate enhancing the intensity of ultrasonic waves reflected from a surface of the cast and reflecting the ultrasonic waves back toward the inner part of the cast.
