STRIP COOLING FOR THE HOT STRIP MILL OF P REUSSAG-STAHL AG

As a follow-on measure to the adoption of a new process automation sys tem for the hot strip mill of Preussag Stahl AG, the strip cooling sec tion has also been modernised. The objective has been to install a new process optimisation and control system by which coiling temperatures can be achieved within close tolerances (+15 K) and differences in th e speed and finishing temperature levels largely compensated for over the length of the strip. For this purpose a mathematical/physical cool ing model optimised on the basis of measured values has been developed as a means of feedforward control.
