Aluminum Smelting Terms
AE, AE Freq.: AE is the abbreviation for anode effect, a rapid rise in pot
voltage that occurs when the bath under some or all anodes becomes
too low in dissolved alumina. AE Freq. is the frequency of anode
effects per pot in the potline. Along with the duration of each AE,
the AE Freq. drives the generation of peruorocarbons, which are
powerful greenhouse gases. Elimination of AEs is always a key
environmental goal for smelters.
Aggregate: The dry coke and butts mix that is then mixed with pitch to bind
it before forming into anodes.
Airburn: This refers to oxidation of the anodes by air and occurs when ...
