Abstract:The anode effect mechanism and fault parameters of aluminium electrolytic cells were studied, and a deep learning-based anode effect prediction method was proposed. It can adapt to the parameters of tank conditions in different dimensions and different data characteristics, and directly mine fault characteristic information from massive raw data. It greatly reduces the response time of the effect, has good robustness and anti-interference ability. At the same time, in the model debugging optimization, the Batch Normalization algorithm and gradient test are used to improve the model convergence speed and stability. The prediction accuracy and F1 score reach 94.65% and 0.9317, respectively. The prediction time can reach 16 min, and it is verified by field experiments to meet the actual production requirements.
Key words: aluminium electrolysis; 300 kA; anode effect prediction; deep learning; optimization
