Abstract

A continuous casting and rolling system for steel strips includes a vertically working two-roll casting device, a first device for adding molten steel to the casting device, a second device for guiding a cast strip produced by the casting device into a horizontal position, a horizontally working rolling mill for working the cast strip, and a reel device receiving the strip worked in the horizontally working rolling mill. Each of the casting device, the first device, the second device, the horizontally working rolling mill and the reel device are controlled by respective individual closed-loop control systems. The system also includes a central control system connected to the first device, the casting device, the second device, the rolling mill and the reel device for an integrated adjustment of the respective individual closed-loop control systems as a function of mathematical models. Each of the first device, the casting device, the second device, the rolling mill and the reel device is an individual component of the continuous casting and rolling system. The central control system automatically controls the individual components with respect to their interaction to produce a stri…
