摘要
Disclosed is a single-point control based feeding method for a pre-baked anode aluminum reduction cell feeder. A feeding port is divided into different regions. Equidistant voltage drop signals are sampled on anode leaders in different regions. The anode current is calculated according to the equidistant voltage drop signal. The aluminum oxide concentration in regions of the feeding port is compared according to the variation trend of the anode current. Feeding control is performed distinguishingly for states of the regions of the feeding port. Through the method, targeted controlling can be performed on the aluminum oxide concentration in each region of the electrolytic cell, thereby improving the accuracy of the feeding control, avoiding precipitation production or effect frequency, being beneficial to stable running of the electrolytic cell, and achieving the effect of saving energy, reducing consumption and improving current efficiency.
