Advanced 20KHz Ultrasonic Processor for Efficient Liquid Aluminum Treatment

In the process of metal solidification, ultrasonic vibration is introduced, the solidification structure changes from coarse columnar crystal to uniform and fine equiaxed crystal, and the macro and micro segregation of metal is improved. It is generally believed that high-energy ultrasound is useful in 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 and other aspects.

The processed melt is stored in a specific container, such as a crucible, smelting furnace, crystallization furnace. There are many ways to transmit ultrasonic energy into the metal melt. Among them, it is undoubtedly the most effective way to insert the ultrasonic tool head into the melt and directly emit ultrasonic waves into the molten metal liquid. When the melt is cooled and crystallized, it is also affected by strong ultrasonic wave, and the material properties change accordingly. For a specific melt, the smaller the melt volume, the greater the output power of the ultrasonic generator, and the longer the ultrasonic action time, the higher the ultrasonic comprehensive action intensity. In other words, we can also control the effect of ultrasonic action by controlling the amount of metal melt, the output power of ultrasonic generator, and the time of ultrasonic action to find the best balance between ultrasonic action and actual effect.
