Abstract

Algorithm to optimise the edging amount for high accuracy plan view control has been developed to improve plate yield. To produce rectangular shape of rolled plate, the edging amount that can minimise the crop length and width deviation must be determined from the operational analysis of plate mill. For the plan view control, new mathematical models to predict crop lengthat the top and bottom ends and width deviation at side ends are developed on the basis of statistics and back propagation learning algorithm of neural network. Using new mathematical models, under given rolling conditions ofbroadside and finishing pass and the permissible tolerance in width deviation, optimised algorithm which can achieve high accuracy plan view pattern is proposed. The application of newly developed algorithm in actual plate mill for plan view pattern control reduced width deviation by 20%, and crop length by 30% on average with a suitable fishtail crop shape.
