One of the most important processes of refining aluminum alloys is degassing - the extraction of hydrogen which creates internal defects and porosity.
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.
EuroGraphite offersthe manufacture of graphite consumables according to customer drawings, including the use of isostatic graphite and EDM graphite.
Production and technological capabilities

Vacuum antioxidant impregnation, heat treatment
Allows the penetration of antioxidant crystals throughout the part, reducing the damaging effects of thermal stress and burnout.
Modeling of the aluminum casting process and the possibility of conducting pilot tests at the factory stand.
The EuroGraphite project was initiated by specialists in metallurgy and mechanical engineering with the aim of implementing R&D research in the field of graphite processing in industrial applications.
For a long time, our research with the support of the Technical University of Ostrava has been focused on improving the efficiency of using graphite electrodes and other carbon products.
Thanks to the successful results of R&D research and a lot of experimental work (for example, in the field of vacuum antioxidant impregnation, graphite dust granulation, the development of new graphite products), we are able to offer for the market innovative products for the metallurgical industry.
Based on the analysis of the initial data of your casting process, we will select the most effective solution in terms of the use of graphite products, help to simulate the refining process, manufacture parts and conduct pilot tests at the factory pilot site (if we are talking about the production of aluminum alloys).
Cooperation with EuroGraphite will help you to significantly improve the efficiency of graphite products, and reduce the cost of purchasing consumable spare parts.
