Sialon alternative for graphite rotor, impeller and shaft for degassing in molten aluminium.
The rotor is composed of a sialon shaft with quick or threaded coupling and by the rotor impeller. The rotor geometry is designed for adapting to degassing devices used in furnaces and ladles. The rotor can be used in a wide temperature range: from 650 to 1400° C. The sialon has excellent non-wetting properties and a very long service life compared to graphite rotors and shafts.
The Sialon rotor shaft impeller is designed to inject and evenly disperse an ascending flow of tiny bubbles of the process gas (inert gas, with a possible addition of chlorine to reduce alkali).
