Detailed Description

Ultrasonic treatment of metal melt in molten metals and alloys Ultrasonic Processing of Metal Melts # Power ultrasound in molten metals and alloys shows various beneficial effects such as structuring, degassing, and improved filtration. # Ultrasonic promotes the non-dendritic solidification in liquid and semi-solid metals. # Sonication has significant benefits on the microstructural refinement of dendritic grains and primary intermetallic particles. # Furthermore, power ultrasound can be used purposefully to reduce the metal porosity or to produce meso-porous structures. # Last but not least, power ultrasound improves the quality of castings. - - - - ITEM | PARAMETER | Frequency | 20Khz | Horn | Ceramics / Titanium alloy | Power | 2000W | Generator | Digital generator | Amplitudes | 10-22m | Max temperaturer: | 850() | - - - - Ultrasonic Solidification The formation of non-dendritic structures during solidification of metal melts influences the material properties such as strength, ductility, toughness, and/or hardness. Ultrasonically altered grain nucleation: Acoustic cavitation and its intense shear forces increase the nucleation sites and number of nuclei in the melt. Ultrasonic treatment (UST) of melts result in a heterogeneous nucleation and the fragmentation of dendrites, so that the final product shows a significantly higer grain refinement. Ultrasonic cavitation causes the even wetting of non-metallic impurities in the melt. Those impurities turn into nucleation sites, which are the starting points of solidification. Because those nucleation points are ahead of the solidification front, the growth of dendritic structures does not occur. According to the different requirements of production equipment, the structure of ultrasonic processor and the size can be changed correspondingly. Ultrasonic special driving power source (supersonic generator) including rectifier circuit, oscillating circuit, amplifying circuit, feedback circuit, the track circuit, protection circuit, matching circuit and display instrument, etc. Used to produce high-frequency high power current, driven by ultrasonic vibration components work. The power adjustable ultrasonic generator, so as to adapt to different working condition. Within the generator can also be according to the need to integrate with timing controller, set control ultrasonic vibration time and interval time. Ultrasound applied in the metal melt processing there are also two special difficulties, namely, high temperature and corrosion. We all know that the core component of the piezoelectric ultrasonic transducer is the piezoelectric ceramic piece, it is only after a high voltage polarization has a piezoelectric properties. If temperature exceeds 80 , the piezoelectric ceramic is depolarization, piezoelectric performance will decline, and the drop is not reversible. Followed by the metal melt temperature is generally high, the temperature of the black metal even more than one thousand degrees. Launch head to immersed in the melt, but also high power ultrasonic launch, will be affected by the ultrasonic dual role of corrosion and the molten metal liquid corrosion. This processor is proposed to design and manufacture of ultrasonic metal melt with high requirements. Fortunately, after successful people unremitting efforts, all these problems have been solved. We will according to the present situation and the requirements of users, tailored to meet the requirement of the users to use metallic melts processor. Application With the typical structure, for example, ultrasonic launch metallic melts the processor is a round bar. After the molten metal, just insert the firing head metal melt, can emit ultrasonic to metallic melts. Vibration system enclosure front flange used for fixation. Due to the ultrasonic vibration system has no moving parts and mechanical parts, the fixed no special requirements. Treated melt in a specific container, such as crucible furnace, crystal furnace. Tool head inserted into the melt, the side of launch ultrasonic wave. In general, it is suggested that in the melt cools down to join ultrasound, to melt in the cooling crystallization was also strong ultrasonic effect. Treated melt quantity may be less more. For specific melt treated the less amount of melt, the output power of ultrasonic generator, ultrasonic action, the longer the ultrasonic synthesis strength is high. Similarly, we also can by controlling the amount of melt, the size of the ultrasonic generator output power, and the ultrasonic action time, to control the intensity of the ultrasonic function. Due to the characteristics of all kinds of metal materials and different requirements, the function and effect of ultrasound is also each are not identical. In view of the performance requirements of the particular metal users, only through trial and error for many times, find the best balance of ultrasound intensity and actual effect, thus, the best processing technology. Function : High power ultrasonic effect on the crystallization of molten metal process, can significantly refine metal grain, homogeneous alloy composition, accelerate the bubble moion, significantly improve the metal material properties, such as strength, hardness, plasticity and toughness.
