Head, and cast in anode joint in charcoal bowl with the phosphorus pig iron, anode joint and aluminium conducting rod are exploded by aluminum steel and weld connection, then
It connect aluminium conducting rod closely with anode carbon block, forms anode carbon block group.During Aluminum Electrolysis Production, anode carbon block can be because of it
It decomposites the oxygen come with alumina eltrolysis constantly to react release carbon dioxide at high temperature and constantly consume, therefore anode carbon block
It needs to regularly replace, remaining carbon block is commonly called as anode anode scrap after replacement.The production technology has the following disadvantages at present, and 1) replacement
New anode carbon block is in normal-temperature, and to be put into electrolytic cell after preheating in about 24 hours could be conductive, therefore replaces anode carbon
Block can be such that heat loss increases, and very big to the stable working impact of electrolytic cell when change poles；2) replacement of anode can be raw to aluminium electroloysis
Producing to be formed periodically influences, and destroys the energy and material balance of electrolytic cell, influences current efficiency, increases power consumption rate；3) in order to
Anode joint is separated with anode anode scrap, needs to break into pieces in the charcoal bowl at phosphorus pig iron casting, keeps anode anode scrap de- from anode joint

Anode anode scrap is 2,600,000~3,900,000 tons/year, is calculated according to 2700 yuan/ton of anode carbon block, and annual China can waste value up to hundred
Hundred million yuan of anode carbon block；4) it because anode carbon block itself has 25%~27% porosity, therefore has been adsorbed in anode anode scrap a large amount of
Electrolyte, the main component of electrolyte are fluoride salts, and the anode anode scrap environmental pollution containing a large amount of fluoride salts is extremely serious；5)
When that will cast in anode joint in charcoal bowl, in order to reduce the waste of anode anode scrap, it is necessary to it is as far as possible that anode anode scrap burning is thin, in sun
Pole carbon block end of lifetime, the top surface of anode carbon block is very close to electrolyte level face, by magnetic field and airflow influence, bath surface
Constantly there is strong wave to generate, in the actual production process, anode joint is often corroded by electrolyte, the ferro element of anode joint
It dissolves in electrolyte, enters aluminium ingot immediately, influence quality of finished；At 3 years or so, this also made to give birth to the general service life of anode joint
It produces cost to increase accordingly, and in anode carbon block end of lifetime, excessively thin anode anode scrap thickness necessarily brings charcoal extremely conductive uneven,
And then leading to electrolytic cell fluctuation of operating conditions, power consumption increases.To improve the usage mode of existing anode carbon block, the life of non-residual electrode is realized
Produce, to reduce cost, not only improvement anode carbon block, it is necessary to be the relevant whole system of anode carbon block is improved, and
If existing aluminium cell will stop slot transformation, fire resistant heat preserving structure, anode stub in pot superstructure and bottom pot shell,
Cathode carbon pieces etc. are scrapped completely, lose huge, and the expense also ten that the structures such as bus, portal frame above electrolytic cell remanufacture
Divide high.
