Definitions

  • the invention relates to a method for adjusting the cooling process of metal strips or metal sheets (rolling stock) across the strip width of a cooling section, e.g. in a hot strip or heavy plate mill or cooling in a continuous annealing/heat treatment.
  • Cooling plays an important role in improving the quality of hot strip or heavy plate.
  • a targeted computer-assisted control of the cooling is known, for example to prevent the strips or sheets from buckling and/or bulging. If there is a lack of control and regulation of the temperature, the desired qualities can no longer be set. So it happens that if the strips or sheets are bent or bulged too much, this cannot be corrected in a subsequent roller conveyor to ensure quality. The consequences are tape errors and an associated increased reject rate.
  • a control device for the rolling stock determines and sets the optimal coolant quantity and coolant quantity profile for the passage through a cooling section. This is intended to ensure the optimal flatness and evenness of the rolling stock to be cooled.
  • strip width areas are cooled differently in a targeted manner in order to improve the flatness of the strip or sheet. This is done taking into account measured temperatures, but these are taken from the surface. After cooling, the temperature distribution in the strip or Sheet metal is not homogeneous and therefore not meaningful in relation to the actual energy content in the material.
  • the energy content of the rolling stock to be cooled is taken into account as an input variable for controlling the cooling section and for determining the amount of coolant in order to specifically remove a certain amount of heat from the rolling stock.
  • a single, fixed value is always assumed here as the starting and target variable. Furthermore, no indication is given as to how the target value can be determined.
  • the JP S64 622 08 A discloses a generic method which serves to uniformly cool hot strip in the width direction over its entire length. This improves the material quality and prevents the generation of an incorrect shape of the hot strip.
  • the temperatures of a pair of movable plates are brought into agreement with the center position in the width direction of the hot strip being passed.
  • the temperature difference T between the temperatures of the middle part and the end part of the hot strip is calculated by comparison arithmetic and compared with a target temperature difference T0.
  • T is larger than T0
  • a signal for narrowing the distances between the movable plates is transmitted to a drive motor controller.
  • the center position of the hot strip is calculated based on the two end positions using the comparison arithmetic.
  • Material width of the rolling stock is determined before cooling, based on which a target enthalpy distribution is determined, taking into account a calculation of the flatness and the mechanical properties using a microstructure model in the width and length direction of the rolling stock, and after this the amount of coolant and the coolant flow of the cooling section are set.
  • a target enthalpy distribution across the width after the cooling section is defined.
  • the input enthalpy distribution can be determined from a computer program, for example. In principle, another thermodynamic potential can also be used instead of the enthalpy.
  • the target enthalpy distribution can be set using various parameters. For example, this is a numerical calculation of the flatness of the strip after the cooling line, which can be optimized based on the target value. With the help of modelling, it is basically possible to calculate the flatness of the finished product in the cold state (i.e. after coil cooling). This is not possible with the help of a measuring device when it is warm. Another option is to define this using a microstructure model so that the goal of setting homogeneous mechanical properties across the width can be met. This is not necessarily the case with uniform cooling and this is also not necessarily the case with uniform enthalpy distribution across the width. Furthermore, the results of various measuring devices that measure a quality variable as a function of the width can also be used as control parameters. This can be, for example, a flatness measuring roller or another flatness measuring device, but also measuring devices for recording the mechanical properties (e.g. Impoc or others).
  • a wide variety of measures can be used as actuators within the cooling section, which make it possible to achieve different enthalpies depending on the width. This can be, for example, edge masking, heating of edges, targeted cooling using multiple control loops across the width, or similar.
  • the target enthalpy distribution can also be determined by optimizing other parameters or empirically based on measurements after cooling.
  • the target enthalpy distribution can be adjusted inhomogeneously across the width.
  • a control can dynamically change the target enthalpy distribution in the rolling stock over the width while the rolling stock is running through the cooling section.
  • the enthalpy calculation can be based on the Gibbs energy, for example.
  • Databases in the SGTE can be used to determine the Gibbs energy, for example to specify the structural components in the rolling stock and to set the cooling to a constant structural phase proportion that is homogeneously distributed over the strip width of the rolling stock and thus to regulate and control the mechanical properties depending on the target enthalpy distribution.
  • An immediate comparison can be made with the mechanical properties calculated in the microstructure model via a measuring point located after the cooling system, and a possible deviation in the target enthalpy distribution can be corrected immediately by activating or switching off the cooling system.
  • the figure 1 shows schematically part of a possible hot strip or heavy plate plant for processing metal strips and/or metal sheets.
  • a measuring device 2 After the last stand 1 of the hot strip or heavy plate mill is a measuring device 2 arranged.
  • the measuring device 2 can be a flatness roller or the like and is arranged in front of the actual cooling section 3 .
  • the measuring device records an actual value of the rolling stock 6 before the cooling section 3.
  • the cooling section 3 can include laminar cooling or intensified cooling or also compact cooling. After the cooling section 3 there is at least one further measuring device, for example a flatness roller or the like, which measures the actual value, for example the flatness of the hot strip/rolled stock 6 after it has passed through the cooling section 3 .
  • a flatness roller or the like which measures the actual value, for example the flatness of the hot strip/rolled stock 6 after it has passed through the cooling section 3 .
  • a calculation model 5 receives the measurement data from the measuring devices 2 and 4 and specifies the amounts of cooling medium to be used accordingly in the cooling section 3 in order to set the target enthalpy distribution. As a result, it can be ensured virtually online that the desired qualities of the rolling stock/hot strip 6 can be adjusted and immediately thereafter coiled into a coil 7 for further processing.
  • Other units for example more measuring devices, descalers, thermal insulation hoods, scissors, etc. can be arranged in the area before and after the cooling system 3 .
  • FIGS 2, 2a, 2b illustrate the enthalpy distribution in the hot strip across the width at the beginning of the acquisition and at the end of the acquisition as well as the difference between the two enthalpies at the beginning and end.
  • Figures 3 illustrates the mechanical properties of yield point and tensile strength (Rp and Rm) across the width of the hot strip.
  • the Figure 3a shows the flatness of the rolling stock across the width.
