Degassing Machine Rotor & Shaft

Degassing machine rotors and shafts are critical components in the molten metal treatment process, particularly in foundries handling non-ferrous metals like aluminum. Their primary function is to efficiently remove dissolved hydrogen gas and non-metallic inclusions, which can lead to significant defects such as porosity in the final casting. The rotor, typically positioned at the end of the shaft, spins at high speeds within the molten metal, creating a vortex and dispersing an inert purging gas (like argon or nitrogen) into fine, uniformly distributed bubbles. This maximizes the contact surface area between the gas bubbles and the molten metal, facilitating the effective flotation and removal of and dissolved gases, ultimately leading to a cleaner, higher-quality melt.
