Abstract

The invention discloses a method for evaluating the control effect of aluminum electrolysis cells. The method comprises the steps that: cell control operation data corresponding to each aluminum electrolysis cell in a set time period are obtained; for the blanking control evaluation result, according to blanking state data, resistance data and voltage data, the blanking control evaluation result of each aluminum electrolysis cell is determined; for the evaluation result of anode lifting and voltage control, the evaluation result of anode lifting and voltage control of each aluminum electrolysis cell is determined according to the blanking state data, the resistance data, the voltage data and the anode lifting process time; and for the evaluation result of the operation and cell stability control, the evaluation result of the operation and cell stability control of each aluminum electrolysis cell is determined according to the voltage pendulum data, the anode effect data, the aluminum discharging process time and the pole changing process time. According to the method, evaluation time consumption can be greatly reduced, evaluation efficiency is remarkably improved, and stable production of the aluminum electrolysis cell is guaranteed.

Description

technical field [0001] The present application relates to the technical field of electrolytic aluminum, in particular to an evaluation method, device and electronic equipment for the control effect of an aluminum electrolytic cell. Background technique [0002] The production process of electrolytic aluminum is to melt the alumina in the molten electrolyte at 920°C to 960°C in the electrolytic cell, and then carry out electrolytic reduction reaction between the carbon anode and the alumina on the two poles through a strong direct current to generate primary aluminum liquid and CO 2 gas process. Due to the high current, strong magnetic field, high temperature, and high corrosion electrochemical production process in the electrolytic aluminum process, the stable and efficient production of the electrolytic cell has always been a key issue that needs attention in the aluminum electrolytic production process. The stability and high efficiency of the aluminum electrolytic produc...
