Automatic Ultrasonic Metal Melt Machine for Aluminum Liquid Processing with Adjustable Holder
The application of ultrasound in aluminum melt treatment mainly focuses on grain refinement, degassing, homogenization of composition, and improvement of casting performance. The following are the specific applications and related contents of ultrasound in aluminum melt treatment:
Principle of ultrasonic aluminum melt/ultrasonic metal melt
Cavitation effect: Ultrasonic waves generate high-frequency vibrations in aluminum melt, forming tiny bubbles that quickly collapse, generating local high temperature and high pressure, and promoting melt flow and homogenization.
Acoustic streaming effect: Ultrasonic waves trigger melt flow, enhance heat and mass transfer, and reduce segregation and inclusions.
Grain refinement: Ultrasonic vibration promotes nucleation, inhibits grain growth, and thus refines grains.
Advantages
High efficiency and energy saving: short processing time and low energy consumption.
Non-contact treatment: avoid the introduction of foreign impurities and reduce pollution.
Wide applicability: suitable for pure aluminum and various aluminum alloys.
Environmental protection: no chemical refiner or degasser is required to reduce environmental pollution.
Main applications
(1) Grain refinement
Ultrasonic vibration can significantly refine the grains of aluminum melt and improve the mechanical properties of the material (such as strength and toughness).
Grain refinement can also improve the processing performance of aluminum materials and reduce cracks and defects.
(2) Degassing
Aluminum melt easily absorbs hydrogen and forms pore defects. The cavitation effect of ultrasound can effectively remove gas from the melt and reduce pores in the casting.
The degassing effect is better than the traditional inert gas purging method.
(3) Homogenization of composition
Ultrasonic stirring makes the distribution of alloying elements in the aluminum melt more uniform and reduces segregation.
For aluminum alloys (such as Al-Si, Al-Mg, etc.), ultrasonic treatment can improve the distribution of eutectic phase.
(4) Improve casting performance
Ultrasonic treatment can improve the fluidity of aluminum melt and reduce defects such as shrinkage cavities and shrinkage during casting.
For thin-walled castings or castings with complex shapes, ultrasonic treatment is particularly effective.
(5) Enhance the performance of composite materials
In the preparation of aluminum-based composite materials (such as Al-SiC, Al-Al₂O₃), ultrasonic treatment can improve the dispersion of reinforcing phases (such as silicon carbide and aluminum oxide) and enhance interface bonding.
Parameter
Impurity RemovalIt is challenging for small inclusions in molten steel to float to the surface, and they only become more easily removable when they accumulate. By introducing ultrasound into the solution using ultrasonic metal melt equipment, ultrasound standing waves can successfully stratify and aggregate the inclusions in the solution.
