Characterstics of graphite rotor

1. With good self-lubricating property.

2. Excellent conductive properties, Resistance coefficient is 8-12 uhm.

3. High Thermal stability, low coefficient of thermal expansion.

4. Good chemical stability, it is not dissolved in organic or inorganic solution; it is not reacted with any solution of salt and alkali.

5. High thermal resistance, The melting point of graphite is up to 3650°C, No deformation under high temperature.

6. High-purity, low impurities. 

the technical data of graphite rotor 

Application:

For degassing (dehydrogen) in molten aluminum or zin when aluminum hubs and other aluminum parts produced.

Our Metal or Resin Impregnated Graphite Parts are widely used in equipments of modern industry, such as seal rings for centrifugal pumps reacting kettle for chemical engineering, hydraulic generators and rotate baking furnaces; piston rings and bushings for compressors oxygen machines and bellows, bearings for screen motors and other types of instruments; slides for motors, subways and mine brushes of electrical machinery and slides for trolleybuses, etc.

The working principle of graphite rotor

Graphite rotor comprises a rotor bar, the nozzle is composed of two parts. The transmission system drives the graphite rotor rotates, argon or nitrogen through the rotor bar, head into the aluminum melt. High speed rotation of rotor graphite into aluminum melt argon or nitrogen scattered into many small bubbles, which are dispersed in the liquid metal, and rotation of the rotor to hydrogen, aluminum melt inclusions within the diffusion, and make the bubble contact, bubbles in the melt by the gas pressure difference and surface adsorption principle, absorption melt in the hydrogen adsorption and oxidation, slag, and the bubble rise and be out of the melt surface, so as to purify the fusant.
