3 Terms and Definitions
YS/T 481-2005, YS/T 784-2012 and define the following terms and definitions apply to this document.
3.1
AE anodeeffect
Aluminum electrolysis process, due to the influence of various superimposed on a combination of factors, the sudden formation of larger gas film resistance, resulting in cell voltage suddenly obvious
Increased and was accompanied by an arc discharge phenomenon around the anode.
3.2
Anode effect beginning beginningofanodeeffect
When the cell voltage transient sudden increase in aluminum reduction cell is greater than the duration of 8V is more than 15s, that the anode effect beginning with the first
The cell voltage is greater than the effect of sample values 8V as the start time point.
3.3
AE end endofanodeeffect
Aluminum cell anode effect into the state, as the process of anode effect, the instantaneous cell voltage is lower than 8V duration of more than 15s,
And the effects do not occur within 15min, considered the end of the anode effect.
3.4
Anode effect duration anodeeffectduration
Aluminum cell anode effect occurs, the start time from the anode effect cell voltage is lower than 8V, and it lasts longer than the time for the 15s
Anode effect duration; if after the end effect again within 15min, the cell voltage is greater than the time duration of the previous duration 8V
Merger between anode effect duration.
3.5
AE peak voltage peakvoltageofanodeeffect
Aluminum cell anode effect occurs during the maximum instantaneous cell voltage anode effect known as the peak voltage.
