Abstract

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.

Description

technical field [0001] The present invention relates to an ultrasonic generating device for controlling coagulated tissue, and more particularly, to a device for preventing some ultrasonic waves from leaking by reflecting the ultrasonic waves on an incident interface. Background technique [0002] Casting is a process used to produce raw materials that serve as a base material and is used to manufacture structures that are widely used in industrial applications, or casting is used to melt a base material and solidify the molten base material into a desired shape craft. As the molten metal cools, the molten metal solidifies into a solid with the desired spatial shape. In this case, the molten metal is quickly fixed from its outer surface. Although the outer surface of the cast iron product is solidified, the interior of the cast iron product, which has relatively slow heat transfer characteristics, remains in a liquid phase and slowly solidifies due to its slow heat transfe...
