Patent ID: 7251971

Claim:
A method for controlling a temperature of strip metal within a technical installation of the steel industry, the strip metal transported through the technical installation, the method comprising: providing a target temperature gradient of the strip metal; route-tracking a plurality of points on the strip metal during the transport of the strip metal through the technical installation; determining a number of temperature gradients for at least some of the points during the transport of the strip metal through the technical installation; determining a target function for a plurality of actuators assigned to a control system of the technical installation, the control system adapted to control the technical installation, based on the determined temperature gradients, the target temperature gradient, and side conditions including factors influencing a temperature control included in the control system; and adjusting the actuators using the target function so that the temperature of the strip metal and the plurality of functions are controlled by the control system, wherein adjusting the actuators includes minimizing or maximizing the target function using a solving algorithm of an optimization problem.
