Graphite rotors and stators for degasators
Industries engaged into molten iron processing, mainly ferrum, copper, aluminiun, non-ferrous alloys, use casting technics with molten iron resistance materials. These materials should not influence the final composition of the iron nor add hard particles that may cause problems during technical treatment into the melt. Graphite is the ideal material for such ambient. Graphite is widely used in all spheres of aluminium industry. During casting it is used as rotors and stators in degasators and ensure free from contamination casting.
Rotary impellor or static tube injects inert gas into the molten iron.
Thermal shock resistance excludes the necessity of pre-heating.
Easy machinability makes graphite the ideal material for any form required.
Tokai Carbon also produces extrusion-type
graphite, grades FE200 and FE250 suitable for this kind of application.

Post-mechanincal treatment.
Resistibility of a part can be three times higher than this of an unptreated one.
Graphox, the unique impregnation, protects the graphite surface without changing its size.
