Continuous Casting and Rolling Installation For Producing a Steel Strip

A continuous casting and rolling installation for producing a steel strip, comprising the following components:

• a liquid steel storage device;
• a liquid steel charging device;
• a vertically operating casting device with a revolving mold;
• a diverting device for diverting a cast steel strip into a horizontal position;
• a horizontally operating rolling mill;
• a winding device, wherein the components are controlled by a plurality of technological control loops, each control loop assigned to one of the components;
• a control system for adjusting the technological control loops in an integrated manner, wherein the control system connects the liquid steel storage device, the liquid steel charging device, the casting device, the diverting device, the rolling mill, and the winding device, wherein the control system operates on the basis of mathematical models, and wherein the control system coordinates an interaction between the components, wherein the coordination of the interaction takes into consideration effects of a control step applied to one of the components on a component arranged downstream of the one component relative to a mass flow direction;
• and
• a reduction device arranged between the mold and the diverting device, wherein the reduction device has a plurality of roll pairs, and wherein the reduction device is controlled by one of the technological control loops which is also controlled by the control system, wherein
• the control system contains a material model for modeling a thermal behavior of the steel or steel strip on a transportation path from the steel storage device to the winding device using path tracking, and wherein
• the technological control loops are controlled using the modeled thermal behavior of the steel or steel strip according to a correct control timing.
