Definitions
- the invention relates to a method for operating a cooling section of a plant for producing rolled products, wherein the cooling section is operated using a physical cooling model, which is adaptable to the respective cooling task using at least one adaptation value associated with a particular process parameter.
- the invention relates to a system for producing rolled products, comprising at least one rolling train, in particular a hot strip mill or a plate mill, at least one downstream of the rolling mill cooling section and at least one cooling circuit driving the control electronics, wherein control electronics is set up, the cooling section using a physical cooling model to operate, which is adaptable to the respective cooling task using at least one adaptation value associated with a particular process parameter.
- a plant for producing rolled products can be designed, for example, for the continuous production of metal strips.
- Such a plant may have a hot strip rolling mill, which is connected downstream of a cooling section.
- a cooling section is usually operated using a physical cooling model of the cooling section and the rolling stock to be cooled.
- conventionally adaptation algorithms are used on the basis of which the cooling section is controlled.
- Such an adaptation algorithm searches in certain parameter classes for an adaptation value with which the given operating mode the cooling section can be adapted to the next cooling task.
- Such an adaptation value is determined empirically in advance and stored.
- corresponding physical models have been partially replaced by interpolation variants.
- GB 2 484 917 A discloses a method of cooling a metal plate.
- a target cooling flow is calculated for a plurality of points along the length of a longitudinally profiled plate.
- the position of the metal plate is monitored with respect to flows in a refrigerating machine. Further, the flows are set according to the target cooling flows at the plurality of points.
- the target cooling flows may be interpolated to produce a reference profile along at least a portion of the length of the metal plate.
- the method may include calculating an expected entrance thickness and temperature of the metal plate at the plurality of points and comparing these with measured values to calculate a required flow change. The method ensures that the exit temperature of the metal plate is accurately controlled by the chiller, even if the metal plate has different thicknesses along its length.
- JP H06 218 414 A discloses a cooling control method for hot-rolled steel sheet. The temperature of the steel sheet is calculated by using a prescribed temperature estimation formula using
- JP 2010 005 682 A discloses a cooling device between a finishing mill of a hot rolling mill and a flange, wherein the cooling device is subdivided into a first and a second second Flalbzone.
- a metal strip is cooled differently, and the temperature of the metal strip is measured by a near-infrared camera capable of photographing a full length or part of the full length so that the temperature of the hot-rolled metal strip is controlled immediately before winding can be.
- US 8 920 024 B2 discloses a steel plate quality assurance system and apparatus therefor, wherein the steel plate quality assurance system has a temperature of at least one steel plate production line having a finish rolling line of a steel plate production line and an accelerated cooling device disposed in the feed direction of the steel plate production line on the downstream side of the finish rolling line measures the upper surface of a steel plate or the lower surface of the steel plate to perform quality assurance.
- the system includes temperature measuring means, temperature analyzing means and means for determining mechanical properties.
- US 2016/0288181 A1 discloses an operating method for a cooling zone, wherein a flat rolled material is transported through a cooling zone in such a way that sections of the rolling stock pass successively effective regions of cooling devices.
- Virtual rolling stock points are assigned to the sections.
- the cooling devices are controlled such that they correspond to the actual cooling performance at the respective rolling stock points, which are assigned to the cooling devices. Thereby is that portion which is in each case in the effective range of the respective cooling device, applied to a respective amount of coolant.
- the cooling devices are subdivided into open and unopened cooling devices.
- a rolling stock point is selected in each case iteratively. Before the respective section, starting from a starting point, reaches the effective range of the next released cooling device, a state is determined which the respective rolling stock point has at the starting point.
- An object of the invention is to improve an operation of a cooling section of a plant for producing rolled products.
- the independent claims are given in the following description, the dependent claims and the figure, these embodiments each taken alone or in various combinations of at least two of these embodiments can represent each other a further developing, especially preferred or advantageous, aspect of the invention.
- the cooling section is operated using a physical cooling model that can be adapted to the respective cooling task by using at least one adaptation value associated with a particular process parameter.
- the adaptation value is determined using a Kriging method from at least one predetermined adaptation value. The determination of the adaptation value using the kriging method from the at least one predetermined adaptation value allows extrapolation of known adaptation values to unknown process areas.
- the use of the Kriging method or Kriging algorithm for determining the adaptation value for adapting the cooling section to the respective cooling task in combination with the physical cooling model makes it possible to calculate adaptation values for areas for which no empirical values are available, which ultimately leads to a better settlement of the cooling section allowed.
- a Kriging method is originally a geostatic method that allows you to estimate missing values and their accuracy based on distributed measurement points. This is an unknown point using the basic formula
- Z (x,) is a known value at the point x, w, a weight to be determined, N the number of known values, xo the position for which the value Z * interpolates and m (Xi) is the expected value of Z (x,).
- the adaptation values of the cooling section can be divided into different classifications, such as the classifications "strip thickness”, “strip reference temperature” and “selected cooling strategy". If the different classifications are interpreted as spatial variables of an adaptation value, surfaces are interpolated in the selected dimensions and provided with estimation methods in the Kriging method.
- Rolling stock such as blanks (edge waves, center waves, quater buckles and the like); but also various preliminary processes could be processed by the Kriging process.
- Blanks edge waves, center waves, quater buckles and the like
- various preliminary processes could be processed by the Kriging process.
- Adaptation algorithm for the cooling section are provided in order to improve the prediction accuracy of the temperature calculation can. This allows a more accurate setting of the cooling section and thus a better
- an adaptation value to a predetermined temperature value at a specific position of a rolled product to be cooled becomes a predetermined one
