Abstract

Es soll eine Einrichtung zum Betrieb einer mehrgerüstigen Walzstraße angegeben werden, mit der der Aufwand und die Zeit für die Projektierung, Prüfung und Inbetriebnahme einschließlich der Optimierungsphase sowie für ein erneutes Anwalzen der Walzstraße deutlich verringert wird und gleichzeitig eine gefahrlose Schulung des Betreiberpersonals während des Betriebes sowie eine leichte und sichere Funktionserweiterung ohne Beschädigung der Walzstraße möglich ist. Dazu ist die gesamte Walzstraße in den technologischen Zusammenhängen der einzelnen Gerüste in einem einzigen physikalischen Simulations-Modell (2) gegliedert nachgebildet. Das Simulations-Modell (2) ist mit einer zentralen Regelungsvorrichtung (1) verbunden, die für die gesamte Regelung der Walzstraße allein zum Einsatz kommt und die wahlweise einzelne Funktionen innerhalb jedes Gerüsts oder einzelner Gerüste entweder über Stellglieder der Walzstraße oder in entsprechenden Gliedern des Simulations-Modells (2) steuert.

Figure 00000001
A facility for operating a multi-stand rolling mill is to be specified, with which the effort and time for project planning, testing and commissioning, including the optimization phase and for re-rolling the rolling mill, is significantly reduced and, at the same time, safe training of the operating personnel during operation and an easy and safe functional expansion is possible without damaging the rolling mill. For this purpose, the entire rolling mill is replicated in the technological context of the individual stands in a single physical simulation model (2). The simulation model (2) is connected to a central control device (1) which is used alone for the entire control of the rolling mill and which optionally has individual functions within each stand or individual stands either via actuators of the rolling mill or in corresponding links of the simulation -Models (2) controls.
