Description
Gegenstand des Hauptpatentes 1 000 156 ist eine Zelle zur Herstellung von Aluminium hoher Reinheit durch Schmelzflußelektrolyse, welche gekeimzeichnet ist durch Verwendung nebeneinander angeordneter vorgebrannter kontinuierlicher Anoden, wobei die einzelnen Anoden eine Breite von etwa 200 bis maximal 700 mm, eine Länge von über etwa 1400 mm, einen gegenseitigen Abstand unter etwa 150 mm, vorzugsweise 40 bis 50 mm, und eine Strombelastung von weniger als 10 000 Amp., vorzugsweise 5000 bis 8000 Amp., haben.The subject of the main patent 1 000 156 is a cell for the production of aluminum of high purity by fused-salt electrolysis, which is marked by using juxtaposed pre-fired continuous anodes, the individual anodes having a width of about 200 to a maximum 700 mm, a length of over about 1400 mm, a mutual distance of less than about 150 mm, preferably 40 to 50 mm, and a current load of less than 10,000 amps, preferably 5000 to 8000 amps.
Durch diese Bemessung der einzelnen nebeneinander 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 vom erzeugten Metall aufgenommen werden und damit den Reinheitsgrad des Metalls herabsetzen.This dimensioning of the individual anodes arranged next to one another enables the production of aluminum high purity possible because it succeeds in the path and speed of the electrolysis resulting, the impurities in gas or smoke form with leading anode gases so too design so that the mentioned impurities are not absorbed by the metal produced and thus reduce the purity of the metal.
Überraschenderweise wurde nun gefunden, daß dieses Ziel auch dann erreicht werden kann, wenn die Dimensionen der Einzelanoden sowie die Strombelastung derselben über das Maß hinaus gesteigert werden, wie dieses Gegenstand des Hauptpatentes ist. Dementsprechend ist der Gegenstand der vorliegenden Erfindung eine Zelle zur Herstellung von Aluminium hoher Reinheit durch Schmelzflußelektrolyse, in welcher nebeneinander angeordnete vorgebrannte kontinuierliche Anoden zur Anwendung gelangen, die eine Länge von über etwa 1400 mm, einen gegenseitigen Abstand unter etwa 150 mm, vorzugsweise etwa 40 bis 50 mm, aufweisen, wobei das Kennzeichen der Erfindung darin erblickt wird, daß die Anoden eine Breite von mehr als 700 bis 1000 mm besitzen und eine Strombelastung von 10 000 bis etwa 20 000 Amp. haben.Surprisingly, it has now been found that this goal can also be achieved if the Dimensions of the individual anodes as well as the current load of the same increased beyond the measure how this is the subject of the main patent. Accordingly, the subject matter of the present Invention a cell for the production of high-purity aluminum by fused-salt electrolysis, in which pre-fired continuous anodes arranged next to one another are used, the one Length of over about 1400 mm, a mutual distance below about 150 mm, preferably about 40 to 50 mm, the characteristic of the invention being seen in that the anodes have a Have a width of more than 700 to 1000 mm and a current load of 10,000 to about 20,000 amps. to have.
Im übrigen ist die Anordnung und Gestaltung der Anoden ebenso wie diejenige im Hauptpatent.Otherwise, the arrangement and design of the anodes is the same as that in the main patent.
