Ultrasonic metal melt equipment uses the cavitation effect of ultrasound in the melt to cut off and destroy dendrites, impact the solidification front, increase stirring and diffusion, make the organization uniform, and at the same time increase the tensile strength of metal materials and improve the toughness of metals. The small grains and large boundary area can effectively prevent dislocation and intercrystalline slip, which means that more force is required to break the material. The finer the grains, the smaller the dendrite spacing, the higher the yield strength, and the better the hardness. The ideal ingot structure is a uniform and fine equiaxed crystal on the entire cross section of the ingot. This is because the equiaxed crystal has small anisotropy, uniform deformation during processing, excellent performance, good plasticity, and is conducive to casting and subsequent plastic processing. To obtain this structure, the best method at present is to use ultrasonic metal melt equipment to perform ultrasonic refinement on the melt.
Ultrasonic degassing improves grain refinement and structure of aluminum alloys. In addition to ultrasound facilitating the removal of non-metallic gas inclusions from aluminum liquid, ultrasonic-driven metal melt processing has become an excellent technology for producing high-quality metal castings.
The function of ultrasonic metal melt:
Remove impurities: It is very difficult for tiny inclusions in molten steel to float up, and only when they gather together will it be easier to float up. Using ultrasonic metal melt equipment to add ultrasonic waves to the solution, ultrasonic standing waves can successfully stratify and aggregate the inclusion powder in the solution.
Ultrasonic degassing: Ultrasonic waves have a great effect on removing gases from molten metals, and ultrasonic elastic vibrations can completely degas the alloy within a few minutes. When ultrasonic vibrations are introduced into molten metal, cavitation is found to occur. This is because the continuity of the wave phase is broken and a cavity is generated, so the gas dissolved in the liquid metal is concentrated in it. The elastic vibration of the ultrasonic wave promotes the formation of the bubble core and makes it grow continuously until it grows to a size that can be smoothly discharged from the molten metal.
Improve the quality of the ingot: Ultrasonic metal melt equipment can act on the crystallizer to improve the surface quality of the ingot. Ultrasonic vibrations on the crystallizer can be used for billets, billets and slabs, and negative sliding is not required when using ultrasonic vibrations. When casting billets and billets, a very smooth billet surface can be obtained after applying ultrasonic vibrations to the crystallizer.
Grain refinement: When ultrasonic vibration solidification is used to produce castings, the ultrasonic wave will generate positive and negative alternating sound pressure during propagation, forming a jet. At the same time, due to the nonlinear effect, it will generate acoustic flow and micro-acoustic flow, and ultrasonic cavitation will generate high-speed micro-jets at the interface between solid and liquid. The cavitation effect of ultrasonic waves in liquid can cut off and destroy dendrites, impact the solidification front, increase the stirring and diffusion effect, and can achieve the effects of purifying the organization, refining the grains, and making the organization uniform. In addition to the mechanical action caused by vibration to destroy dendrites, another important function of ultrasonic vibration solidification is to increase the effective supercooling of the molten metal, reduce the critical nucleus radius, thereby increasing the nucleation rate and refining the grains.
High temperature resistance: the maximum temperature can withstand 800ºC.
Corrosion resistance: Use high-strength titanium alloy tool head.
Significant effect: Micro-molecule interaction, the effect is direct and obvious.
Easy installation: through standard flange docking installation, there is no need to change the customer's existing production equipment and process flow.
