aluminum degassing

The degassing is achieved by blowing and saturating the aluminum melt with an inert gas (the most often, argon or chlorine), which comes to the surface reacting with hydrogen.

Consumable tools for degassing are graphite impellers. Plunging into the aluminum melt, they create a channel for supplying inert gas to the depth of the ladle and, with the help of a rotating rotor, distribute gas bubbles throughout its volume.

EuroGraphite products - high-quality graphite impellers are provided with the following characteristics:

- Increased resistance to thermochemical stresses is achieved by using special types of graphite and the technology of vacuum impregnation of parts with antioxidants;
- The design of the impellers and the parameters of their rotation create the necessary structure of gas bubbles that enter into diffusion with hydrogen, turbulence, circulation, depending on the requirements of the technological process.
