Definitions

  • the invention relates to a method for producing a metal having a plurality of phase components, wherein the thermoformed metal is cooled in a cooling section, wherein in a first step with the aid of primary data for the metal by means of a cooling section model, the temperature and at least a phase portion of the metal at least one point the cooling section is calculated. Furthermore, the invention relates to a computing device for the corresponding control and modeling of a cooling section and a corresponding system for producing a metal with a plurality of phase components.
  • From the DE 101 29 565 A1 is a cooling method for a hot-rolled rolling, in particular a metal strip known.
  • an initial temperature is detected in front of the cooling section for a Walzgutstelle, using a cooling line model and predetermined desired properties of the rolling a coolant flow rate determined, applied to the Walzgutstelle according to the determined temporal coolant flow rate a coolant, based on thedeoxynmodells and the temporal coolant flow rate expected temperature curve of the rolling stock at the Walzgutstelle determined over the Walzgutquerites and dissolved to determine the temperature profile in the rolling stock in the cooling section model, a heat equation, which sets the enthalpy, the thermal conductivity, the degree of phase change, the density and the temperature of the rolling relationship.
  • expected temperature curves of the metal strip are compared with target temperature profiles. Based on this comparison, a new coolant flow rate is calculated.
  • Hot-formed metals produced and cooled in accordance with known processes often do not or do not meet with sufficient reliability the properties or material properties required for their subsequent use.
  • This object is achieved by a method of the type mentioned, in which in a second step at least one temperature measurement is detected in the production of the metal and with the aid of the at least one temperature measurement by means of the cooling line model at least one point of the cooling section at least one expected phase proportion of the metal is calculated, wherein the calculated in the second step expected phase component is compared with the phase component calculated in the first step and this comparison is used to adjust at least one manipulated variable of the cooling section.
  • the phase proportions at the end of the cooling section over the metal can be kept substantially constant.
  • the at least one manipulated variable of the cooling section deviations between different bands with the same primary data are largely eliminated.
  • the at least one phase component is calculated in such a way that the fluctuations of the system do not enter into the calculation, ie a reference conversion factor is determined.
  • this reference conversion level is regulated, the actual fluctuations in the system being largely compensated for by adapting local control variables of the cooling section.
  • the at least one point at which at least one phase portion of the metal in the first or in the second step of the method is calculated, located at the end of the cooling section.
  • the expected phase component calculated in the second step is advantageously compared with a predefined phase component in the second step. In this case, it is no longer necessary to compare the expected phase component calculated in the second step with the phase component calculated in the first step. In this way, direct specifications, for example of an operator, are taken into account when setting the phase component.
  • the second step is done online, i. executed in real time during the production of the metal iteratively.
  • the accuracy of the method is further improved.
  • At least one manipulated variable of the cooling section is adapted in accordance with the comparison by a cooling line controller. Due to the comparison of the phase components, the cooling-gap controller adapts directly to the control variables of the cooling section according to the calculations from the first or second step. This ensures high control accuracy.
  • a cascaded control structure wherein the cooling distance controller from a higher-level phase controller setpoints are specified.
  • the phase component adjusts at least one setpoint for the cooling line controller and the cooling line controller adjusts at least one manipulated variable of the cooling section, taking into account given preset values.

  • cooling in several cooling sections are sizes such as holding time and holding temperature particularly critical for the phase components in metal.
  • At least one manipulated variable for coolant actuators is adjusted.
  • Coolant actuators are local actuators of the cooling section and therefore, for example, have no effect on a precast line upstream of the cooling section. The finishing train is thus not affected by the adaptation of the manipulated variables for the coolant actuators in an undesirable manner.
  • At least one manipulated variable for the speed of the metal in the cooling section is advantageously adapted.
  • the speed of the metal in the cooling section can largely be influenced independently of the speed at which the metal of the cooling section passes through upstream system parts.
  • At least one manipulated variable is adjusted for a lying time of the metal in the production of heavy plate.

  • the cooling section 5 has one or more actuators 2.
  • the actuator 2 is - usually by cooling, in some cases, but also by heating - directly or indirectly, the temperature T of the metal 1 influenced.
  • An actuator 2 may, for example, have one or more valves for applying a cooling medium to the metal 1.
  • the cooling medium for example, water or a mixture of water with other substances can be used.
  • the cooling section 5 is controlled by the computing device 3.

  • the computing device 3 can also be supplied, for example, with the rotational speeds of the rolls of a roll stand 4 as measured values and / or calculated or modeled values.
  • the computing device 3 are also fed so-called primary data P.
  • Primary data P are generally used for the precalculation or presetting of a plant and depend on the metal 1 to be produced. Different metal bands or slabs are usually characterized by different primary data. Primary data may also relate at least partially to the required properties of the produced metal 1.
  • FIG. 2 shows the profile of the temperature T of the metal 1 in the cooling section 5 plotted over the time t.
  • the time t refers to the time during which a band point of the strip 1 in the form of metal 1 passes through the cooling section 5.

  • the temperature T is used in its capacity as a quantity describing the energy content of the metal 1. It would therefore be possible, for example, alternatively to consider the course of the enthalpy over time t or over the strip running direction x.
  • the phase fractions P i of a metal 1 are particularly critical but also critical in the production, in particular in multiphase steels such as dual phases and tripod steels.

  • the temperature T of the metal 1 or the steel decreases only slightly.
  • the metal 1 is quenched to the temperature T or below the temperature T which is to be reached at the end of the cooling section or immediately before winding by means of the reeling device 12.

  • a residual austenite content of typically 20% is usually aimed at before the quenching begins.
  • a retained metastable retained austenite content remains in the material at room temperature, which converts to martensite upon deformation.
  • the constant maintenance of the phase components P i and thus the degree of conversion in the cooling section 5 is extremely critical. If undesired surface temperature impairments, for example so-called skid marks on the metal 1, in this case a steel slab, are caused, for example, in a hot rolling line upstream of the cooling section 5, these undesired skid marks lead to soft spots in the metal strip. At such soft points, the degree of conversion in the metal 1 has already progressed too far prior to quenching to form enough martensite or bainite. Other variations of the process parameters in the cooling section 5 upstream devices may cause further deviations from the desired structure and the desired phase components P i in the metal 1.
