A method for optimizing the band wide distribution at the ends of a rolling mill train or a plurality of passes in a continuous strip

摘要

Method of optimising strip width control at the ends of a strip (2) rolled single or multi-pass on a rolling line (1), whereby the setting position of the edge rolls (4) in every successive pass is adjusted during the passage of the strip ends according to a control diagram (fi) defined by parameters (Si) predetermined by means of a neural network (11) for all passes on the basis of rolling process parameters (x). The adaption of the neural network (11) follows as a function of a strip width error (E1) and other errors (E2i..... E5i) defining exceeded process-technological limits.
