Mathematical modeling, auto-adaptive control and hands-off automation (normal in rolling flat products) have been extended to the more complex area of beam and section rolling. Benefits realized include: improved dimensional accuracy; optimum rolling time; maximum throughput; early achievement of target dimensions; and rapid product change. AUTOMATIC control of the rolling process in some form is familiar in most mills and simple, stored, setup of roll gaps is widespread. To achieve the highest performance, a full setup calculation is required. Such a calculation demands complex mathematical models of the rolling process to enable accurate prediction of the behavior of the rolled metal and the mill. In addition, the models and the setup benefit from constant automatic monitoring and correction or adaption to insure that they continue to predict the mill behavior as precisely as possible.
