  • the process sequence in a continuous annealing line is as follows: first, strips are unwound in the inlet of the line of reels and the ends are connected in a welding machine to form an endless belt. Thereafter, the belt passes through a cleaning section to remove any residual surface contamination from cold rolling. This is followed by a tape store that decouples an inlet area from the process area. In the following oven, the strip goes through a multi-stage annealing process: preheating, heating, holding, rapid and slow cooling, over aging and final cooling. There are special temperature curves for each steel grade and strip geometry in the oven
  • Page 2 be set. This also applies to the transition region around the weld during material and / or geometry changes.
  • a strip accumulator is available that compensates downtime in the spout. If necessary, the strip then runs through a skin pass mill, in which the surface of the strip is provided with a defined degree of roughness and the desired material properties are set. This is followed by a tape storage, which compensates for the inspection and Coil Touch Meeting.
  • Other stations include a trimmer for adjusting the belt width, a quality inspection station and a surface protection oiling machine. Finally, the tape is cut by a pair of scissors and wound up from reel to coil.
  • the temperature profile and the belt speed are the decisive factors for the quality in the annealing in such a continuous annealing. While a strip is in the annealing line, it essentially ensures that the temperature profile in the furnace remains within certain limits. This indirectly sets the quality of the mechanical properties. Also for the transitions between two bands the temperature profile is the essential quantity.
  • European Patent Application EP 2 557 183 A1 discloses a method in which the mechanical properties are to be better adjusted over the strip length.
  • a controller reacts to the predicted mechanical properties. This method is described for changes over the tape length or parts of the tape, that is, also for changes from coil to coil.
  • a model is used in which at least one band-specific input variable is supplied with reference to a point or a section of the rolling stock.

If the simulated value deviates from a predefined setpoint value, at least one process variable of the heat treatment line or the continuous annealing line is controlled or regulated so that a model-predictive control takes place.
  • the problem with this method is that at the beginning of each new annealing cycle at the inlet of a new band in the annealing furnace, the previously issued by the controller manipulated variable must be changed. In the case of the known method, there is initially possibly a "wrong" manipulated variable, which then only has to be adjusted to the "correct” value. This means that the manipulated variable must first be "captured” again at the beginning of a new annealing cycle.
  • the invention is therefore based on the object to provide a solution which makes it possible to achieve an improvement of the control and / or regulation behavior.
  • This object is achieved by a method for controlling a heat treatment plant for heat treatment of steel strip according to claim 1 and a heat treatment plant for heat treatment of steel strip according to claim 3.
  • the object is achieved in that in the event that the at least one manipulated variable in the course of the current annealing or heat treatment cycle of an initial value

  • the predecessor and successor band is taken into account, i. Homogenization is not only possible over more than one strip length, but also from band to band.
  • the control variable for the annealing is adapted from band to band by means of a regulator, the transitions between the bands are particularly delicate. In the method according to the invention, this is part of the overall strategy. If the information is available as to which hot-rolled strips the annealed strip is made up of, it can also be reacted to in the method according to the invention. In the event that the predicted mechanical

  • the plant according to the invention is in particular a continuous annealing line, a galvanizing line or another line for the heat treatment of steel, which comprises at least one annealing furnace.
  • Possible input data for the model for the mechanical properties in the annealer are annealing cycle data, such as belt speed
  • Further input data for the model is the model for the sizes, the material, in particular the mechanical properties at the end of the hot rolling mill or after the hot rolling mill or a mechanical properties meter at the end of the hot rolling mill or after the hot rolling mill.
  • Further possible input data are the cold rolling degree or a model for cold rolling, as well as information for tracking cuts and, if available, information on which part of the hot strip or cold strip the band to be annealed is composed. If a galvanized strip is made from a hot rolled strip, it indicates how much has been separated from the hot rolled strip. If an annealed strip is made up of various hot-rolled strips, it is defined how the annealed strip is composed of hot-rolled strips. If necessary, further process parameters of the plant or of the preliminary processes can be used.
  • Cycle manipulated variables may include, for example, the annealing temperature, holding time, temperature after any cooling range, heating or cooling rates, belt speed, the skin pass rate (if a skin pass mill is provided), the degree of stretch (if stretch levelers are present) and other process parameters. that describe the process. For every steel grade, there is a set of manipulated variables that has an influence on the mechanical properties of the steel grade.
  • the focus can be placed on deviations over the strip length or deviations from strip to strip. If only differences from band to band are considered, that means that the input data of the
  • Page 7 Pre-processes are assumed to be constant over the tape length. But there may still be differences over the tape length. Especially in this case, the transition between the bands is important because the beginning of the tape and the end of the tape are exposed to different conditions in the system to ensure the transition from the previous band or to the subsequent band.

  • minimum and maximum values are considered.
  • the temperature after slow cooling is a suitable manipulated variable to influence the strength.
  • the new kiln control can use the existing means for determining the temperature profile in the first step, then the curve for the tensile strength is determined. Now, the course of the temperature after slow cooling is adjusted so that the resulting tensile strength over the band is as constant as possible. If the tensile strength does not change too quickly across the belt and the tensile strength always increases as the temperature increases after slow cooling, or if it decreases as the temperature is reduced, the predetermined course can be corrected. If the tensile strength over time and the possible settings for the temperature after slow cooling is applied, resulting in an area. The intersection of this surface with the plane passing through the initial value of the tensile strength gives the values for the slow cooling temperature which must be used to keep the mechanical properties constant.
  • Page 9 For certain grades of steel, the following course of the mechanical properties after the anneal can be obtained over the strip length, with stable operation of the annealing furnace, and this can be due to behavior in the hot rolling mill. It may be that the successive coils have the same direction of the course or the opposite direction of the course. It is typical that successive coils have similar process routes and thus the course goes in the same direction. This behavior can also be deliberately reversed by wrapping a tape. If this is the case, then the best behavior of the controller is achieved.

This may be just around the weld, so that the area is then cut off or completely within the first or second coil, since the effects on the mechanical properties are less for the other coil than for the one coil.
  • measurements for the material properties at the beginning or in the furnace can also be used.
