Abstract:
A method of optimizing a band width distribution at ends of a band passing through a mill train, comprising the steps of:adjusting a position of upsetting rollers during the passage of the ends of the band according to a curve described by predefined parameters; predicting, using a neural network, a band width distribution as a function of process parameters of a rolling process of the mill train and the parameters of the curve; determining an error between the predicted band width distribution and a measured actual band width distribution; adapting the neural network as a function of the error to reduce the error; iteratively determining optimum values of the parameters of the curve using the adapted neural network for which a difference between the predicted band width distribution and a predefined specified band width distribution is minimum; and adjusting the position of the upsetting rollers as a function of the optimum values of the parameters of the curve.
