Anode anode scrap is 2,600,000～3,900,000 tons/year, and according to 2700 yuan/ton of calculating of anode carbon block, annual China can waste value up to hundred
Hundred million yuan of anode carbon block；4）Because anode carbon block has 25%～27% porosity in itself, therefore anode anode scrap internal adsorption is substantial amounts of
Electrolyte, the main component of electrolyte is fluoride salt, and the anode anode scrap environmental pollution containing a large amount of fluoride salts is extremely serious；5）
When just anode joint is cast in charcoal bowl, in order to reduce the waste of anode anode scrap, it is necessary to anode anode scrap is burnt thin, in sun as far as possible
Pole carbon block end of lifetime, the top surface of anode carbon block are sufficiently close to electrolyte level face, by magnetic field and airflow influence, bath surface
Constantly there is strong wave to produce, in actual production process, anode joint is often corroded by electrolyte, the ferrum element of anode joint
Dissolve in electrolyte, immediately into aluminium ingot, affect quality of finished；Anode joint generally uses the life-span at 3 years or so, and this also makes life
Producing cost accordingly increases, and in anode carbon block end of lifetime, excessively thin anode anode scrap thickness, necessarily brings charcoal extremely conductive uneven,
And then cause electrolysis bath fluctuation of operating conditions, power consumption to increase.Want to improve the occupation mode of existing anode carbon block, realize the life of non-residual electrode
Produce, with reduces cost, not exclusively improve anode carbon block, it is necessary to be that the related whole system of anode carbon block is improved, and
If existing aluminium cell will stop groove 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 structure such as bus, portal frame above electrolysis bath is remanufactured
Divide high.
