Abstract

Electrode columns made from carbon and graphite are screwed together from individual elements, for example, the electrodes and nipples. The elements have directionally structured contact surfaces. Such a structure of the contact surfaces gives rise to the elements of a column demonstrating increased resistance to loosening after intensive machine screwing or screwing applied by hand, which, therefore, is often inadequate, whereby a higher level of operational reliability is achieved, in particular, in the case of electrode columns that are screwed together by hand.
