Ultrasonic Aluminum Melt Equipment
May 03, 2018

Ultrasonic aluminum melt equipment is a high-power ultrasonic equipment specially used in the metal casting industry. Ultrasonic aluminum melt equipment can effectively refine the grain and homogenize the microstructure of 7055 aluminum alloy melt, increase its tensile strength, and can significantly improve its plasticity.

Ultrasonic aluminum melt equipment applications


It is mainly used in the continuous cooling casting fields such as gravity casting and low-pressure casting of light metals, such as aluminum alloy and magnesium alloy sheet casting and mold casting.

Refinement of the metal grains and uniform alloy composition significantly improves the strength and fatigue resistance of the cast material and improves the overall performance of the material.


Ultrasonic aluminum melt equipment principle


Ultrasonic melt processing system is composed of ultrasonic vibration components and ultrasonic generators. Ultrasonic vibration components are used to generate ultrasonic vibrations. They mainly include ultrasonic transducers, ultrasonic horns, and tool heads (emission heads). Energy is emitted into the metal melt.


The transducer converts the input electrical energy into mechanical energy, ie ultrasonic waves. The manifestation is that the transducer moves back and forth in the longitudinal direction with an amplitude of typically several micrometers. This kind of amplitude power density is not enough and cannot be used directly. Ultrasonic horns need to amplify the amplitude according to the design, isolate the metal melt and thermal energy transmission, and also play the role of fixing the entire ultrasonic vibration system. The tool head is connected to the horn, and the horn transfers the ultrasonic energy vibration to the tool head. The tool head then transmits the ultrasonic energy into the metal melt.


The metal melt receives ultrasonic waves in the process of cooling or pressing, and its crystal grain structure, etc., will produce significant changes, thereby improving various physical properties of the metal.
