steelUltrasound is a compressed longitudinal wave, which can
effectively propagate in gas, liquid, solid, solid melt and other
media, and has strong penetrability. Ultrasonic waves can transmit
strong energy when propagating in liquid media, can produce strong
impact and cavitation on the interface, and, like sound waves, can
produce reflection, interference, superposition and resonance.
Under the condition of the same amplitude, the intensity of
ultrasonic waves is much greater than ordinary sound waves. It has
been used in the metallurgical industry and has achieved certain
results in industrial applications. Ultrasonic metal melt
equipment ismainly used in the metallurgical industry. Under
ultrasonic vibration conditions, it is conducive to the degassing
of the metal solution, the removal of impurities, the refinement of
grains, and the strengthening of the leaching process. Ultrasonic
metal melt equipment is used in molten metal, which can realize the
composite of fiber and metal in a very short time, and prepare
high-performance composite materials. Under the action of
ultrasound, the liquid metal can penetrate into the particle
preform or evenly mix with the particles. Ultrasonic dip plating
can realize the galvanizing and aluminizing of the steel
wire. Features High temperature resistance: the
highest temperature is 1300ºC.Corrosion resistance: Use
high-strength titanium alloy tool heads.The effect is remarkable:
the effect is direct and obvious with the interaction of
micro-molecules.Easy to install: through standard flange butt
installation, no need to change the customer's existing production
equipment and process flow. What
is the difference between ultrasonic homogenisers and ultrasonic
baths?The power of ultrasonic baths is fixed. The power density
[W/l] is relatively low.Ultrasonic homogenisers have an adjustable
power [W] and produce very high power densities. Probes with a
defined radiating surface guarantee reproducible results.What is
more important when choosing the appropriate device - power rating
or amplitude?Power output is not the sole criterion for selecting
the ultrasonic homogeniser. This value only indicates the power of
the ultrasonic generator but not the energy delivered into the
sample.The amplitude at the radiating surface of the probe is the
determining factor while considering the sample volume. RPS-SONIC
homogenisers provide higher amplitudes than comparable devices in
the market due to an optimal matching of all components Remove
impuritiesIt is very difficult for the tiny inclusions in molten
steel to float up, and only when they gather will it make it easier
to float up. Use ultrasonic metal melt equipment to add ultrasonic
waves to the solution. The ultrasonic standing wave can
successfully stratify and agglomerate the inclusions and powders in
the solution. Ultrasonic degassingUltrasound has a great
effect on removing gas from molten metal, and ultrasonic elastic
vibration can completely degas the alloy within a few minutes. When
ultrasonic vibration is introduced into molten metal, it is found
that cavitation occurs. This is because the continuity of the
liquid 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 generation 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 billetsUltrasonic metal solution equipment can act
on the mold to improve the surface quality of the cast slab.
Ultrasonic vibration of the mold can be used for billets, blooms
and slabs, and there is no need for negative sliding when
ultrasonic vibration is used. When casting billets and blooms, a
very smooth surface of the cast slab can be obtained after
ultrasonic vibration is applied to the mold. Grain
refinementWhen the casting is produced by the ultrasonic vibration
solidification method, the ultrasonic wave will produce positive
and negative alternating sound pressure when propagating, forming a
jet. At the same time, due to the nonlinear effect, it will produce
acoustic and micro-acoustic flow, and ultrasonic cavitation will
produce at the interface of solid and liquid. High-speed microjet.
The cavitation effect in the ultrasonic liquid can cut off and
destroy the dendrites, impact the solidification front, and
increase the stirring and diffusion effect, which can achieve the
effects of purifying the structure, refining the grains, and making
the structure uniform. In addition to the mechanical action caused
by vibration to destroy dendrites, another important role of
ultrasonic vibration solidification is to increase the effective
undercooling of the molten metal, reduce the critical nucleus
radius, thereby increase the n
