Abstract: The corrosion rates of 5N-NIFE Oa inert aodes were investigated as a function of main operatin
parameters by grey relational analysis. The results show that grey relational analysis is a novel data process
method and is used to rank the correlation extent of effect factors in the inert anode system. The analysis of
practical data hw that the prior factors causing corosion are alumina concentration, bath temperature, cr
olitic ratio, area ratio of cathode to anode and current density in turn. Corrosion analyses are consistent with
experimental results, An ar ificial neural network(NN)ased solution me o ology for modeling anode corro
sion procesed from observed experimen al values, and ANN model were developed by usin the cited methodoh
ogy for the prediction of the co sion rate of inert ade in aluminum electrolysis. The experimental result
shows that ANN model holds promise to be an effective and efficient tool for the construction of analytical moch
els associated with corrosion process of inert anodes in cryolite- based melts
y words: aluminum electrolysis; inert amde corrosion grey relational analysis; artificial neural network
