Abstract
This study has fully considered the mechanical and technological characteristics of a continuous annealing and processing line (CAPL) by proposing the concept of in section shape and out section shape, building a set of in section shape and out section shape prediction models, and quantitatively analysing the differences between them. The paper provides a set of comprehensive control models suitable for CAPL, targeting the best overall section shape, the minimum in section shape and the minimum shape difference between unit exit and the goal; develops a set of online prediction and control software for cold rolling strip shape in CAPL and promotes it in practical production to improve the strip conveying stability and accuracy of exit shape control.
