CUISSON REDUCTRICE [3 records]

Record 1 1998-01-29

English

Subject field(s)
  • Furnaces and Ovens (Metallurgy)
  • Aluminum Production
OBS

Current is led out of the [electrolytic reduction] cell to the anode bus bar by a number of carbon block anodes suspended in parallel rows on vertical conducting rods of copper or aluminum. Because impurities in the anodes dissolve in the bath as they are consumed, pure carbon (calcined petroleum coke or pitch coke) is used as raw material. The ground coke is mixed hot with enough coal tar or petroleum pitch to bond it into a block when pressed in a mold to form the "green" anode. This is then baked slowly at temperatures up to 1100-1200 °C.

Key term(s)
