Analysis and control of a continuous annealing line

A mathematical model of the continuous annealing process has been developed to implement the computer control of an annealing line. The model has been used to derive control equations for interim control of the line during the testing period for the model. Comparison of operating practices with the practices prescribed by the control equations indicates that the equations are sufficient for control of the line, when supplemented by a closed-loop feedback control system. These equations therefore have been utilized as the basis in the development of the steady-state and the dynamic optimizing control schemes.
