Definitions
- the invention relates to a method for adjusting the cooling course of metal strips or metal sheets (rolling stock) over 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-aided control of the cooling is known in order, for example, to avoid edging and / or bulging of the strips or sheets. If there is insufficient control and regulation of the temperature, the desired qualities can no longer be set. So it happens that if the edges or bulges of the strips or sheets are too strong, they cannot be corrected to ensure quality in a subsequent roller conveyor. The consequences are belt errors and the associated increased rejects.
- a control device for the rolling stock determines and sets the optimal coolant quantity and coolant quantity curve for passage through a cooling section. This is to ensure the optimal flatness and evenness of the rolling stock to be cooled.
- a disadvantage here is that the strip width areas are specifically cooled differently in order to improve the flatness of the strip or sheet. This is done taking into account measured temperatures, which are taken from the surface. After cooling, the Temperature distribution in the strip or sheet is just not homogeneous and therefore not meaningful with regard 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 dissipate a specific amount of heat from the rolling stock in a targeted manner.
- a single, fixed value is always assumed here as the start and target value. Furthermore, there is no indication of how the target size can be determined.
- the object of the present invention is to provide an improved method for checking and adjusting the flatness or flatness and / or the mechanical properties of the rolling stock in a hot strip and heavy plate mill. Further advantageous measures are the subject of subclaims.
- this object is achieved by determining the initial enthalpy distribution over the material width of the rolling stock before cooling for the calculation of the cooling, with a target enthalpy distribution taking into account a calculation of the flatness and the mechanical Properties is determined by a microstructure model in the width and length direction of the rolling stock and then the amount of coolant and the coolant path of the cooling section is set.
- a target enthalpy distribution over the width after the cooling section is determined.
- the input enthalpy distribution can e.g. can be determined from a computer program. In principle, a different thermodynamic potential can also be used instead of the enthalpy.
- the target enthalpy distribution can be determined using various parameters. This is, for example, a numerical calculation of the flatness of the strip after the cooling section, which can be optimized based on the target value. With the help of modeling it is basically possible, too calculate the evenness of the finished product when cold (i.e. after the coil has cooled down). This is not possible with the aid of a measuring device in a warm state. Another possibility is to determine 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, for example, be 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 allow different enthalpies to be achieved depending on the width. This can be, for example, edge masking, heating of edges, targeted cooling through several control loops across the width or the like.
- the target enthalpy distribution can also be determined by optimizing other parameters or also empirically based on measurements after cooling. Starting from the initial enthalpy distribution, the target enthalpy distribution can be set inhomogeneously over the width. A control can dynamically change the target enthalpy distribution in the rolling stock across 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, 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 bandwidth of the rolling stock and to regulate and control the mechanical properties depending on the target enthalpy distribution.
- An immediate comparison with the mechanical properties calculated in the microstructure model can be made via a measuring point located after the cooling, and a possible deviation in the target enthalpy distribution can be corrected directly by activating or switching off the cooling.
- Fig. 1 is a schematic representation of the
- Fig. 3 shows the representation of possible
- FIG. 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 is arranged after the last stand 1 of the hot strip or heavy plate plant.
- the measuring device 2 can have 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 upstream of the cooling section 3.
- the cooling section 3 can include laminar cooling or increased 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. arranged that the actual value, for example, the flatness of the cooling section 3
- Hot strip / rolled material 6 after passing through the cooling section 3 measures.
- a computing model 5 receives the measurement data from the measuring devices 2 and 4 and specifies the cooling medium quantities to be used in the cooling section 3 in order to set the target enthalpy distribution. In this way, it can be ensured online, as it were, that the desired qualities of the rolled material / hot strip 6 can be adjusted and can be reeled into a coil 7 immediately afterwards for further processing. Further units, for example more measuring devices, descalers, thermal insulation hoods, scissors, etc., can be arranged in the area before and after cooling 3.
- FIGS. 2, 2a, 2b illustrate the enthalpy distribution in the hot strip viewed 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 the end.
- FIG. 3 illustrates the mechanical properties of the yield point and tensile strength (Rp and Rm) over the width of the hot strip.
- FIG. 3a illustrates the flatness of the rolling stock viewed across the width.
