    摘要: A flat rolling stock of metal passes through roll stands of a finishing train, and a cooling section, in succession. Initial values which characterize the energy content of rolling stock points are determined, at the latest, when said rolling stock points enters into the finishing train. The rolling stock is tracked as it passes through the finishing train and cooling section. The initial values, trackings, and energy content influences are used to determine expected values for the energy content of the rolling stock. The energy content expected for a predetermined location, which lies between the first roll stand and the first cooling device of the cooling section is ascertained and used to determine a target energy content progression, from the predetermined location until the rolling stock passes out of the cooling section. The cooling devices are controlled based on the target energy content progression.

    摘要: A method and a device have high energy efficiency and high descaling performance, with which high-quality rolling stock can be produced. In a method in which the rolling stock is heated in an induction furnace and subsequently descaled, before the rolling stock is rolled in a rolling stand or rolling relay, the heated rolling stock is descaled by at least one rotating water jet from a rotary descaler; then at least one temperature of the descaled rolling stock is respectively recorded by a temperature measuring instrument and delivered to a controller; and the controller determines at least one control parameter with the aid of a control rule and by taking into account a setpoint temperature, and delivers it to a control component, at least one inductor of the induction furnace being driven so that the temperature of the descaled rolling stock corresponds as far as possible to the setpoint temperature.

The invention furthermore pertains to a device for influencing the state of the surface evenness of the strip by means of strip cooling, wherein the cooling device is controlled in dependence on the state of surface evenness of the strip in such a way that the surface unevenness is reduced or eliminated. In addition, this invention makes it possible to purposefully influence the strip contour, wherein the strip or the slab is cooled widthwise in such a way that the strip contour approximates a desired target contour more closely.
