Ultrasonic Metal Melt Equipment

answer:

Metal melt processor

1.) What is the principle of ultrasonic treatment of metal melt?

A: Ultrasound can play two effects on metal solutions, namely mechanical action and cavitation. Since ultrasonic waves are mechanical waves, they are required to be transported by molecular (atomic) interactions in the medium. Therefore, the addition of ultrasonic waves during the casting process can make the internal structure of the medium more uniform, which is called mechanical action. When the ultrasonic sound intensity reaches a certain level, it can excite the cavitation of the liquid, and the air bubbles originally in the liquid will be crushed and discharged. Therefore, the cast metal with high-power ultrasonic treatment has higher grain refinement and stronger strength. Big.

2.) Can the tool head be machined with a material that is resistant to high temperatures and corrosion?

Answer: The materials that can be used for the ultrasonic tool head are limited, mainly aluminum, steel and titanium alloy. Among them, titanium alloy is the best material for ultrasonic, but the common feature of metal is high temperature resistance and corrosion resistance. Not very strong. At present, our company's anti-corrosion coating is applied on the metal surface to enhance the anti-corrosion effect through the coating. Generally, corrosion-resistant and high-temperature resistant materials, such as ceramics, are generally not suitable for ultrasonic equipment, and the main reason is that they are easily broken.

4.) What is the relationship between processing speed and power?

A: Generally speaking, the higher the power, the faster the processing speed. The main reason is that after the power is increased, the vibration generated by the tool head will increase, the ultrasonic wave propagation range will be enlarged, and the collision between the metal particles will be accelerated. The cavitation effect.

5.) Can the equipment be used to handle high temperature metal materials such as copper and iron?

A: Our current standard metal melt processing system is mainly used to treat metals with lower melting points such as aluminum alloys and magnesium alloys. Due to the high melting point of copper and iron, the melting point of the tool head (titanium alloy) currently used by our company is close, so the standard metal melt processing system is not applicable. Of course, if you have a need, we are very willing to customize a non-standard high temperature metal melt processing system for you.

4.) Does the use of an ultrasonic metal processor have a significant effect on improving material properties after metal treatment?

A: Our company has cooperated with research institutes such as Central South University and Shanghai University. The results of this equipment have been verified. They have been affirmed by the foundry experts. The grain refinement is very obvious and the strength is very large. Upgrade.

7.) What are the advantages of the drive generator? Such as timing function, power adjustment, etc.

A: The standard metal melt processing system currently uses the ultrasonic numerical control power supply independently developed by our company. Its main features are high power, high energy conversion rate, automatic frequency tracking, and power adjustment. Due to the high temperature in the metal melt treatment and the large fluctuation of the temperature, when the temperature changes greatly, it will have a huge impact on the ultrasonic equipment, which directly leads to the deviation of the resonance frequency of the ultrasonic tool head. Traditional analog power supplies require manual adjustment of tracking at frequency offsets and are highly susceptible to damage. The company's ultrasonic digital control power supply has an automatic frequency tracking function to ensure that it works at its optimum state within 250 degrees Celsius.

9.) At what point is the ultrasound added? how to use?

A: The ultrasonic metal melt processing system produced by our company is mainly used in the metal casting process, especially in the crystallization process, such as gravity casting and pressure casting. The use of ultrasonic waves in the casting process will result in obvious physical properties of the metal. improve.

10.) Is there a difference between side and vertical use?

A: Ultrasonic metal melt processing systems are typically placed vertically, immersing the tool head in a metal melt. Of course, if it is inconvenient to place vertically, it can be placed sideways, but it must be ensured that the tool head has a certain immersion depth.

11.) Can power be made even bigger? For example, 3000W, 4000W, 5000W.

A: The standard metal melt processing system of our company has a maximum power of 2500W, which can meet the general casting process. If you need more ultrasonic power, our company can customize a more powerful metal melt processing system for you.
