摘要： A steel volume is modeled in a computer by means of a plurality of volume elements. The state of the steel volume at a given time comprises, for each volume element, characteristic quantities of an enthalpy existing at said time in the respective volume element and percentages, in which the steel is available in the respective volume element at the time in austenite, ferrite and cementite phases. For at least one volume element, the computer determines the time gradient of the characteristic quantities by resolving thermal conductivity and phase transition equations. One of the characteristic quantities is a locally invariable mean interstitial element concentration within the volume element in the austenite phase thereof.

摘要： In a method and a control device for adjusting a state of a rolling stock, particularly a near-net strip, defined at least by an out-of-parallel condition and/or a curvature of the rolling stock, the rolling stock is transitioned from an initial into an intermediate state by a roll stand and by impressing a stress onto the rolling stock by an additional processing device, and the rolling stock is transitioned from the intermediate into a final state by at least one processing aggregate. By determining whether rolling stock should be fed into the at least one processing aggregate, the intermediate state requiring a non-zero out-of-parallel condition and/or curvature in order to achieve a predetermined final state, and the roll stand and/or the processing device are controlled and/or regulated as a function thereof to adjust the required intermediate state, the shape reliability of an ultimately parallel, non-curved rolling stock can be increased.

摘要： According to a method, initial temperatures (T1) of strip points (101) are detected when the hot-rolled strip (6) is fed to the production line. The strip points (101) are monitored on their way through the production line. The hot-rolled strip (6) is subjected to temperature influences (delta T) in the production line (3). The strip points (101), the initial temperatures (T1), the monitored values (W(t)) and the temperature influences (delta T) are supplied to a model (9) for the production line (3). The model (9) determines expected actual temperatures (T2) of the strip points (101) in real time and allocates them to the strip points as the new actual temperatures (T2).

摘要： The invention relates to a method for controlling and/or regulating an industrial process for producing or processing products, wherein a physicomathematical model of the industrial process is formed, with which control parameters for controlling or regulating the industrial process are calculated during the production or processing of the product, a number of measurement values is detected, and the model is corrected with a number of primary correction factors, the number of primary correction factors being equal to the number of measurement values. The method is characterized in that the model is corrected with a number of secondary correction factors, such as with a correction factor reflecting the speed of the phase conversion in the rolling mill to be cooled, and in that the number of all correction factors is greater than the number of all measurement values, wherein at least the secondary correction factors are calculated numerically.

摘要： A computer determines a subsequent state of a steel volume, based on an instantaneous initial state of said steel volume and at least one volumetric surface, the temporary influence quantities acting on said steel volume, by resolution of an equation of thermal condition and phase change. The states include for at least one volumetric element of the steel volume, a local distribution in concentration of a alloy element mobile in the steel, the local proportions of the modeled phases of the steel and a quantity describing a local energy content of the steel. The phases include austenite and another phase, generally, ferrite or cementite. In the context of the change equation, the concentration levels of the mobile alloy element, which are located on either side of the phase boundary, between the austenite and the other phase are determined by resolution of a Stephan problem.
