摘要： The invention relates to a method for the individual marking of precooked anodes used in the production of aluminum by electrolysis in the Hall-Heroult process, and to the anodes produced thereby. These anodes are produced by hot compaction of a carbonaceous paste, and according to the invention, during or immediately after such compaction, a plurality of impressions is formed in the upper part of each anode. The impressions are depressions and/or relief portions, constitute a digital coding for the identification number of each anode, and remain legible until withdrawal of the components of the butt of the worn anode from the electrolysis tank. The marking can be carried out using a binary or ternary code, where the reference plane of the zone of the anode which carries the marking corresponds to a first digit, with other digits corresponding to depressions of a particular depth, depressions of a greater depth, or relief portions.
摘要翻译：本发明涉及一种用于在Hall-Heroult方法中通过电解生产铝的预煮阳极以及由此产生的阳极来单独标记的方法。这些阳极通过碳质糊料的热压制而产生，并且根据本发明，在这种压实之前或之后，在每个阳极的上部形成多个印模。印模是凹陷和/或浮雕部分，构成每个阳极的识别号码的数字编码，并保持清晰，直到从电解槽中取出磨损的阳极的对接部件。标记可以使用二进制或三进制代码进行，其中承载标记的阳极区域的参考平面对应于第一数字，其他数字对应于特定深度的凹陷，较深的凹陷，或释放部分。
