Ultrasonic metal melt processing system is also known as high-power metal casting equipment. It mainly acts on the crystallization process of molten metal, can significantly refine the metal grain, uniform alloy composition, accelerate the bubble movement, and significantly improve the strength and hardness of metal materials.
The ultrasonic melt treatment system does not change the existing production equipment and process flow, and is easy to install and operate. Ultrasonic metal melt treatment system can be used in metal ultrasonic treatment, ultrasonic metal treatment, ultrasonic grain refinement, ultrasonic metal solidification, ultrasonic melt defoaming, ultrasonic crystallization, ultrasonic cavitation, ultrasonic casting, ultrasonic solidification structure, ultrasonic metal continuous casting, etc.
application area
It is mainly used in gravity casting, low pressure casting and other continuous cooling casting fields of light metals, such as aluminum alloy, magnesium alloy plate casting, mold casting, etc.
Main functions
The results show that the strength and fatigue resistance of casting materials can be significantly improved by refining the metal grains and homogenizing the alloy composition.
working principle
Ultrasonic metal melt treatment system is composed of ultrasonic vibration component and ultrasonic generator: ultrasonic vibration component is used to generate ultrasonic vibration, mainly including ultrasonic transducer, ultrasonic horn and tool head (emitter), and the vibration energy is transmitted to metal melt.
The transducer converts the input electrical energy into mechanical energy, namely ultrasonic wave. Its manifestation is that the transducer moves back and forth in the longitudinal direction, and the amplitude is generally in a few microns. Such amplitude power density is not enough to be used directly. The ultrasonic horn amplifies the amplitude according to the design requirements, insulates the metal melt and heat transfer, and also plays the role of fixing the whole ultrasonic vibration system. The tool head is connected with the horn, which transmits the ultrasonic energy vibration to the tool head, and then the ultrasonic energy is transmitted to the metal melt by the tool head.
When the molten metal is cooled or pressed by ultrasonic wave, its grain structure will change significantly, so as to improve the physical properties of metal
