Description

  

  Zelle     zur    Herstellung von     Aluminium    hoher     Reinheit       Nach dem Patentanspruch des Hauptpatentes ist  eine Zelle     zur        Herstellung    von Aluminium hoher  Reinheit durch     Schmelzflusselektrolyse    dadurch ge  kennzeichnet, dass sie nebeneinander angeordnete,       vorgebrannte    kontinuierliche Anoden aufweist, wobei  die einzelnen Anoden eine Breite von 200 .bis 700     qmm,     eine Länge von über 1400 mm, einen gegenseitigem  Abstand unter 150 mm und eine Strombelastung von  weniger als 10 000     Amp.    haben.  



  Durch diese Bemessung der     einzelnen    nebenein  ander angeordneten Anoden wird die     Erzeugung    eines  Aluminiums hoher Reinheit möglich, da es gelingt, den  Weg und die Geschwindigkeit der bei der Elektrolyse       entstehenden,    die     Verunreinigungen    in Gas- oder  Rauchform mit sich führenden Anodengase so zu  gestalten, dass die genannten     Verunreinigungen    nicht  von dem erzeugten Metall aufgenommen werden und  damit den Reinheitsgrad des Metalls herabsetzen.  



       überraschenderweise    wurde nun     .gefunden,    dass  dieses Ziel auch     dann    erreicht werden kann, wenn  die     einzelnen    Anoden eine Breite von 700 bis  1000     mm.        und        eine    Strombelastung von bis zu    20000     Amp.    haben und im übrigen die im Patent  anspruch des Hauptpatentes     angeführte        Gestaltung     und     Anordnung    aufweisen. Zweckmässig     beträgt    der       gegenseitige    Abstand der Anoden 40 bis 50 mm.



  Cell for the production of aluminum of high purity According to the patent claim of the main patent, a cell for the production of aluminum of high purity by fused-salt electrolysis is characterized in that it has pre-fired continuous anodes arranged next to one another, the individual anodes having a width of 200 to 700 square mm, have a length of more than 1400 mm, a mutual distance of less than 150 mm and a current load of less than 10,000 amps.



  Through this dimensioning of the individual anodes arranged next to one another, the production of aluminum of high purity is possible, since it is possible to design the path and the speed of the anode gases resulting from the electrolysis, the impurities in gas or smoke form with them so that the named impurities are not absorbed by the metal produced and thus reduce the purity of the metal.



       It has now surprisingly been found that this goal can also be achieved if the individual anodes have a width of 700 to 1000 mm. and a current load of up to 20,000 amps. And otherwise have the design and arrangement specified in the claim of the main patent. The mutual spacing of the anodes is expediently 40 to 50 mm.
