Resistance to fast temperature changes during melt treatment
When immersed in the melt, the graphite component is raised from room temperature to several hundred degrees Celsius in fractions of a second. At the same time, it is subjected to the cold flushing gases. The application itself requires a high degree of strength as the rotating gas distribution systems are immersed in the melt while turning. In addition, chemical resistance to the highly corrosive environment must be guaranteed.
Graphite components for gas flushing treatments of aluminum melts
Solutions for systems of all sizes in the aluminum industry
We offer solutions for systems of all sizes. You can rely on our extensive, in-depth knowledge in the development of anti-oxidation impregnations in connection with our standard portfolio. In addition, we are experienced design partners when it comes to effective solutions for gas flushing treatments. We will also provide active support as your partner in trouble shooting for any possible faults.
We enable special dimensions
The electrodes for roughing up aluminum surfaces represent a good example of the capabilities of our standard portfolio: Here we are able to realize lengths of up to 2900 mm. We have also supported the design of crucibles in the format 250 x 1000 x 2300 mm.
Materials
Thanks to their material properties such as extreme corrosion resistance and stability at high temperatures and temperature shocks, our specialty graphites are ideal materials for gas flushing treatments and contribute to a significant service life extension.
Improvement in service life with SIGRAFINE® HLM-NOX und HLM-ENOX
In addition, our HLM-NOX and HLM-ENOX brands exhibit low permeability and non-wettability by non-ferrous metal melts. This combination of properties leads to demonstrable improvements in service life of up to 180 %.
SIGRAFINE R4800 - Innovation in shaping
With SIGRAFINE R4800, we have developed a brand considered to be unrivalled on the markets. This specialty graphite which is used for the production of casting rings for casting tables, significantly improves the accuracy of the shaping stage in the manufacture of cast aluminum ingots – particularly when considering the surface quality of the ingot cast. Consequently, all leading systems manufacturers (OEMs) are relying on R4800 today.
