Abstract After analysing the traditional mathematic model of rolling force, a prediction method of rolling force based on the artificial bee colony Algorithm and back propagation neural network is presented, which is used in aluminum hot tandem rolling. The initial weights and threshold values of back propagation neural network are optimized by artificial bee colony algorithm. The training and testing samples are collected from the finishing mills. Comparing with the Sims mathematical model and back propagation neural network, the experimental results show that the prediction accuracy and error of rolling force is superior to that of the traditional methods.
