Máquina de desgasificación de aluminio

Máquina de desgasificación de aluminio graphic rotor that driven by motor come down to liquid aluminum and rotate into it, at the same time, high purity nitrogen (or Argon) and refining agent will be introduced into it, then can get degassing, deslagging and refining function. The machine can be movable, fixed and suspension type.

Dado que en la fusión del aluminio y de las aleaciones de aluminio hay grandes cantidades de hidrógeno e impurezas metálicas y no metálicas, Si estas impurezas nocivas no se eliminan antes de la fundición, provocarán poros, inclusiones de escoria, contracción y otros defectos de fundición tanto en la superficie como en el interior de las piezas fundidas, lo que afecta gravemente a las propiedades físicas, químicas y mecánicas de la fundición, así como a su capacidad de transformación posterior.

Aluminum Degassing Machine use argon or nitrogen as a refining medium, remove hydrogen, impurity from motel aluminum, graphic rotor put into molten aluminum, bring refining gas into molten aluminum through high speed rotation graphic rotor, small bubbles will be produced and evenly dispersed in molten aluminum after graphic rotor and liquid aluminium high speed contact, as hydrogen partial pressure of bubble is zero and molten aluminum hydrogen partial pressure is high, the hydrogen of liquid aluminum will spread into the bubble gradually, at the same time, liquid aluminum metallic and non-metallic impurity will be absorbed on the bubbles surface. The bubbles that carry the impurity float on the top, so as to remove the hydrogen and impurity from liquid aluminium.

Aluminum Degassing Machine Features
High efficiency for degassing, greatly reduce the NG products that blowhole, slag inclusion, shrinkage caused. Improve the rate of finished products;
Environmental friendly, no pollution, use argon or nitrogen as the refining medium, can work with refining flux for better effect;
Reduce refining cost and labor strength;
No corrosion to the crucible furnaces and transfer ladles;
Minimize the secondary pollution in processing procedure;
El eje principal de la máquina cuenta con rodamientos resistentes a altas temperaturas y un motor con sistema de refrigeración por aire, lo que reduce la temperatura de funcionamiento del motor y prolonga su vida útil.
Set the emergency shutdown button, simple and safe operation, strong structure, less maintenance
The rotor rotating speed can adjusted in real time by frequency converter, convenient for using in different degasing and refining situations
