Abstract

Bei längsgestellten Elektrolysezellen, insbesondere zur Herstellung von Aluminium, fallen hohe Investitions- und Betriebskosten für Schienenanordnung außerhalb der Zelle an. Die erzeugten Magnetfelder bewirken außer­ dem die Ausbildung von Metallströmungen. In the case of longitudinal electrolysis cells, in particular for the production of aluminum, high investment and operating costs for rail arrangement outside the Cell. The generated magnetic fields also cause which the formation of metal currents.

Wenn mindestens die in Stromrichtung (I) letzten Kathodenbarrenenden beidseits der Elektrolysezelle (10) über Stromschienen (20) zum stromauf liegenden Ende (24) bzw. zum stromab liegenden Ende (26) geführt wer­ den, entsteht eine Asymmetrie, welche die schädlichen Einflüsse der Magnetfelder verhindert und sowohl Inve­ stitions- als auch Betriebskosten senken hilft. If at least the last ones in the current direction (I) Cathode bar ends on both sides of the electrolytic cell (10) via busbars (20) to the upstream end (24) or to the downstream end (26) who Asymmetry arises, which the harmful Influences of magnetic fields prevented and both inv Reduce stitions and operating costs.
