Embodiment Construction

[0027] An exemplary embodiment of the present invention is explained in detail with reference to the drawings. The single FIGURE here shows schematically and in a greatly simplified manner the method of operating a continuous tempering train 2 which, together with the tempering frame 4 , is part of a treatment line 6 . In the treatment line 6 the rolling stock, here a strip 8 of steel, is subjected to a heat treatment. The adjustment of the continuous annealing unit 2 and the smoothing frame 4 is realized here by means of a control device 10 which includes a model 12

[0028] When a defined point or section of the strip 8 enters the continuous tempering unit 2 , the input parameters E of the strip for this point or section are transferred to the model 12 . The input parameters E are in particular material properties of the strip, for example the chemical composition, surface roughness or grain size of the strip 8 . The input parameters can relate to a point of the strip, a s...

Abstract

A band-specific input variable (E) relative to a point or a portion of the rolling stock (8) of a model (12) is generated, and at least one material characteristic (ME) of the rolling stock is simulated by the continuous annealing process, with the help of the model and is compared with a predetermined desired value. If the simulated material property deviates from the predetermined desired value, at least one of the process variables (T,V) is regulated before or during continuous annealing of the section of the rolling stock in the continuous annealing line (2). An independent claim is included for a computer program for operating continuous annealing line.

Description

technical field [0001] The invention relates to a method for operating a continuous annealing train for processing rolled products, in particular metal strips. Furthermore, the invention relates to a computer program, a control device for a continuous annealing train and a continuous annealing train. Background technique [0002] After hot and cold rolling of a metal strip, for example consisting of steel, the strip is subjected to a heat treatment in order to set the desired material properties in the strip. This heat treatment is carried out industrially, for example, in so-called continuous annealing lines. In a continuous annealing train, the strip is unrolled and passed continuously through the furnace. [0003] During the heat treatment in continuous annealing plants, the aim is to optimize the individual strips with the highest possible throughput, not only within the strip but also from strip to strip with a consistently high quality that is as constant as possible...
