Molten aluminium degassing machine
Molten aluminium refining machine
Automatic molten aluminium refining degassing machine is special equipment designed and manufactured by our company to refine aluminum liquid.
The device is driven by a motor to drive a graphite rotor immersed in a crucible, and high-purity nitrogen gas is feed into the aluminum liquid through a graphite rotor.
The refining agent can be charged to the aluminum liquid through an external powder feeding device.
The aluminum liquid and nitrogen or argon and the refining agent achieve the purpose of degassing and slag removal under the certain rotation of the graphite rotor.
Aplikasi
Automatic molten aluminium refining degassing machine is suitable for the refining of aluminum liquid in the crucible, molten pool and transfer ladle.
Applicable furnace diameter Φ200-1700mm, furnace depth 500-1000mm, can also be designed according to the requirements.
The equipment has the advantages of reliable operation, easy operation, perawatan mudah, convenient graphite rotor replacement, Tempat tidur pendingin ekstrusi aluminium.
It is ideal equipment for aluminum liquid refining in aluminum casting factories.
Degassing principle
Hydrogen has a high solubility in aluminum liquid, which reduces the physical properties and machinability of castings. To cast high-quality castings, the hydrogen content of the aluminum liquid must be kept at a low level.
The small rotor of the degassing refining equipment can effectively disperse the inert gas into small bubbles, which are evenly dispersed and floated in the aluminum liquid.
The partial pressure of hydrogen in the aluminum liquid is higher than that in the bubble, and the hydrogen gas will diffuse into the inert gas and float up to the liquid surface with the bubble, thereby effectively reducing the hydrogen content in the aluminum liquid.
Kecepatan ekstrusi harus dikontrol dengan hati-hati selama proses ekstrusi, the floating bubbles bring the fine inclusions in the aluminum liquid to the surface of the aluminum liquid and are captured and removed by the covering agent.
