FOR THE ALUMINUM INDUSTRY

 

1) Gas injection tubes and distribution systems made of graphite for refining aluminum melts

    가) Properties
       - Minimal wettability by non-ferrous metal melts
       - High thermal shock and oxidation resistance
       - Chemical inertness
       - Non-melting characteristics
       - Dimensional stability
       - Good mechanical strength
       - Very low permeability
    나) Forms supplied and applications
       - Gas injection tubes made of high-density
          graphite in all standard diameters and lengths
       - Purpose-made graphite systems for the uniform
          distribution of refining gas in molten metal
       - The specialty graphite grades are impregnated to
          provide extra oxidation protection

       - High-permeability specialty graphites with
          defined porosity
    나) Forms supplied and applications
       - Specialty graphite rings in diameters of up to 500
         mm, precision-machined to very close tolerances
       - Ready-made rings with gastight and high
          temperature-resistant coatings 


4) Electrodes for electrolytic aluminum etching plants

    가) Properties
