rotary degasser is one of the aluminum liquid degassing equipment consists of a rotor immersed in molten aluminum. The rotor rotates rapidly, generating eddy currents that promote the removal of hydrogen and other impurities by exposing molten metal to inert gases with a large surface area. This process contributes to the effective degassing of aluminum.
2 Impeller degasser:
The impeller degasser uses a rotating impeller to stir molten aluminum and generate a flow pattern that facilitates the escape of dissolved gases. The impeller can be made of graphite, ceramics, or other materials.
3 Flux injection degasser:
The working principle of a flux injection degassing machine is to inject flux into molten aluminum. The flux reacts with impurities and gases to form dross, which floats to the surface and can be skimmed off. This method can effectively remove hydrogen, alkali metals, and other impurities.
4 Ultrasonic degasser:
The ultrasonic degasser uses high-frequency sound waves to stir molten aluminum.
Stirring promotes the release of dissolved gases and helps to remove impurities. Ultrasonic degassing is particularly useful for removing small bubbles.
5 filter degasser:
The filtration degasser combines the degassing process with the removal of solid impurities. These systems use porous ceramic or graphite filters to capture gas and solid particles, ensuring that molten aluminum is cleaner and more refined.
The selection of aluminum liquid degassing equipment depends on various factors, such as the required degassing level, impurities present in aluminum, production requirements, and cost considerations. Each type of degasser has advantages and limitations and should be selected based on the specific needs of aluminum casting or refining processes.
Although other types of aluminum liquid degassing equipment, such as impeller degassing machines, ultrasonic degassing machines, and flux injection degassing machines, have their advantages and applications, rotary degassing machines have gained widespread acceptance and become the preferred choice in the aluminum industry due to their effectiveness, efficiency, and reliability. Easy to implement.
