Metallurgical Metal Solution Degassing Ultrasonic Technology 20Khz High Power

Description:

Ultrasonic metal melt equipment is mainly used in the metallurgical industry, in the ultrasonic vibration conditions, the metal solution is conducive to degassing, de-impurities, refining the grain, and strengthening the leaching process, etc. Ultrasonic metal melt equipment applied to the molten metal solution can achieve the compounding of fibers and metals in a very short period of time, and high performance composite materials are prepared. The liquid metal can penetrate into the particle preform or mix evenly with the particle under the action of ultrasound, and ultrasonic dip plating can realize steel wire galvanization and aluminum plating.

Principle:

Ultrasonic metal melt treatment equipment utilizes the cavitation effect of ultrasonic waves in the melt, which can cut and damage dendrites, impact the solidification front, increase stirring diffusion, homogenize the structure, and increase the tensile strength of metal materials, improving metal toughness. The grain size is small and the boundary area is large, which can effectively prevent dislocations and intergranular slip, meaning that greater force is required to fracture the material. The finer the grain size, the smaller the dendrite spacing, the higher the yield strength, and the better the hardness. The ideal ingot structure is a uniform and small equiaxed crystal on the entire cross-section of the ingot, with low anisotropy of equiaxed crystals. It has uniform deformation, excellent performance, and good plasticity during processing, which is conducive to casting and subsequent plastic processing. The best way to obtain this type of organization currently is to use ultrasonic metal melt treatment equipment to refine the molten metal through ultrasonic treatment.

When producing castings through ultrasonic vibration treatment, ultrasonic waves generate alternating positive and negative sound pressure during propagation, forming a jet. At the same time, due to nonlinear effects, sound and micro sound flows are generated, and ultrasonic cavitation generates high-speed micro jets at the solid-liquid interface. The cavitation effect in ultrasonic liquids can cut off and destroy dendrites, impact the solidification front, increase stirring and diffusion, and achieve the effects of purifying tissues, refining grains, and homogenizing tissues. In addition to the mechanical effect of damaging dendrites caused by vibration, another important role of ultrasonic vibration solidification is to increase the effective undercooling of the molten metal, reduce the critical nucleation radius, thereby increasing the nucleation rate and refining the grains.
