     LSA series aluminum refing degassing machine is a special device for aluminum refining and gas removal. This device is used to inject inert gas into liquid aluminum through rotating graphite rotor and rotary wheel, and then the inert gas inside the liquid aluminum will be dispersed into large amounts of small bubbles which are dispersed uniformly inside the liquid metal, and then those inert gas bubbles will absorb hydrogen and other oxide  impurites from the alumnum melt through partial pressure difference and surface adsorption, thus hydrogen and impurities are removed from the liquid aluminum. The small and dispersed bubbles will mix with aluminum melt uniformly, and float slwoly upwards spirally along with the rotation , so as to prolong contact time with auminum melt, and will not form continuous straight up airflow, thus the refining and purifying effect is improved significantly. This device possesses advantages of reliable operation, easy operation ,easy maintenance and convenient replace ment of graphite rotor, so it is an ideal device for aluminum refing and gas removal in aluminum casting factories .

Advantages of degassing machine

  1. Applies to a wide range. It is convenient to place anywhere. It can carry out degassing operation for many furnaces in different places, and can be locked.

  2. Electric lifting ,which is convenient for rotor positioning and replacement of graphite rod and graphite baffle.

  3. The control operation is easy to learn, switchable from automatic to manual, available for automatic control.

  4. Degassing time can be set, automatic landing for degassing. The indicator light will flash to alarm after degassing is finished,and than rise sutomatically.

  5. It can be used safely by only one person.

  6. Nitrogen or argon is used efficiently, degassing time is reduced and degassing operation can be done automatically.

  7. High degassing efficiecy, and possess good degassing effect repeatability.

  8. Remarkable degassing effect, improve casting yield and mechanical properties of aluminum castings.

  9. Optimum ratating speed of rotor and gas flow rate can be set according to different viscosity of liquid aluminum.

Using nitrogen or argon as the refining medium, there is no pollution to the workshop environment ,and no corrosion to the ladle and the crucible lining.
