摘要
Method for manufacturing anodes used for the production of aluminium by fused bath electrolysis, said anodes comprising an anode stem made of a conducting metal and at least one block made of carbonaceous material called an anode block, said method including at least the following steps:a) obtain an anode stem;b) obtain a new anode block;c) fix one end of the anode stem onto the anode block, so as to give good mechanical attachment and good electrical connection between said stem and said anode block;said method being characterised in that before, during or after step c), but before placement of said anode in the electrolytic cell, a protective layer with a controlled thickness, typically between 5 and 25 cm composed of a material resistant to temperature and corrosion by the medium above the electrolytic bath is at least partially deposited on the upper surface of said anode block.展开▼
