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
It falls to realize separation, the process is not only time-consuming, but also labor intensity of workers is big, low efficiency；4) the anode anode scrap under replacing generates
Amount is generally the 10%~15% of aluminium ingot yield, is 26,000,000~27,000,000 tons/year of calculating by China's aluminium ingot yield, annual to generate
Anode anode scrap be 2,600,000~3,900,000 tons/year, according to 2700 yuan/ton of anode carbon block calculate, annual China can waste value and reach
10000000000 yuan of anode carbon block；4) it because anode carbon block itself has 14%~18% porosity, therefore has been adsorbed in anode anode scrap big
The electrolyte of amount, the main component of electrolyte are fluoride salts, and the anode anode scrap environmental pollution containing a large amount of fluoride salts is very tight
Weight；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 anode anode scrap be burnt as far as possible
Thin, in anode 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, electricity
Solution matter surface constantly has strong wave to generate, and in the actual production process, anode joint is often corroded by electrolyte, anode joint
Ferro element dissolve in electrolyte, immediately enter aluminium ingot, influence quality of finished；The general service life of anode joint at 3 years or so,
This also increase accordingly production cost, and in anode carbon block end of lifetime, excessively thin anode anode scrap thickness necessarily brings charcoal pole to lead
It is electric uneven, and then lead to electrolytic cell fluctuation of operating conditions, power consumption increases.
