  • the cooling process is usually determined by a temporal temperature profile.
  • Older strategies prescribe a distribution of the coolant quantity according to a predetermined cooling strategy and a reel temperature or cooling end temperature (i.e., the temperature of the rolling stock at the outlet of the rolling stock from the cooling section). For normal steels, this procedure is easy. For steels with high carbon content, however, problems arise. Because due to the heat of transformation occurring during the phase transformation of austenite into ferrite and cementite, the specification of a temperature profile is unfavorable. In many cases, even only one final temperature to be achieved is specified in conjunction with a predetermined cooling strategy. This type of specification may even be ambiguous, i. H. There is more than one solution to the amount of water at which, given the cooling strategy, the reel temperature or end temperature is reached. However, the material properties of such differently cooled steels are fundamentally different from each other.
  • From the EP 1 732 716 B1 is an operating method for a cooling section for cooling a rolling stock, in which the input side of the cooling section, the temperature of the rolling stock is detected. It is determined a coolant flow rate, so that a Walzgutabites at a predetermined point of Cooling section has a predetermined temperature and at least one predetermined phase portion (for example, austenite).

  • the initial enthalpy is generally completely determined only when, together with the initial temperature, at least one initial phase share value of the rolling stock is known. It is possible that the initial phase proportion value of the control device is fixed. Alternatively, the controller may accept the initial phase share value from an operator of the cooling line or an external device. It is also possible for the control device to determine the initial phase proportion value.

  • a cooling section 1 is usually downstream of a hot rolling mill. Shown here is in FIG. 1 only the last mill stand 2 of the hot rolling mill.
  • the cooling section 1 is usually further downstream of a reel assembly 3.
  • the cooling section 1 has a roller table 4, in which a rolled out of the rolling mill rolling stock 5 with a liquid coolant 6 (usually water with or without additives) is applied.
  • the cooling section 1 has for this purpose a plurality of coolant outlets 7, which can be controlled individually or in groups by a control device 8 for the cooling section 1.
  • the control device 8 controls the entire cooling path 1, that is to say not only the coolant outlets 7, but also, for example, the cooling of rollers of the roller table 4.
  • the control device 8 is generally designed as a programmable control device 8, which executes a computer program 9 during operation.
  • the computer program 9 in this case comprises machine code 10, which is directly executable by the control device 8.
  • the execution of the machine code 10 causes the control device 8 to operate the cooling section 1 in accordance with an operating method according to the invention.
  • the computer program 9 may already have been deposited in the control device 8 during the production of the control device 8. Alternatively, it is possible to supply the computer program 9 to the control device 8 via a computer-computer connection.
  • the calculator-computer connection is in FIG. 1 not shown here. It can be designed, for example, as a connection to a LAN or to the Internet. Again alternatively, it is possible to store the computer program 9 on a data carrier 11 in machine-readable form and the computer program 9 of the control device 8 via the To feed data carrier 11.
  • the design of the data carrier 11 is arbitrary nature. For example, it is possible that the data carrier 11 is designed as a USB memory stick or as a memory card. Is shown in FIG. 1 an embodiment of the data carrier 11 as a CD-ROM.
  • the control device 8 receives information TA, which is at least partially characteristic of an initial enthalpy value EA of the rolling stock section 12.
  • the information TA which is at least partially characteristic of the initial enthalpy value EA in this case comprises an initial temperature value TA.
  • the initial temperature value TA can in principle be supplied to the control device 8 in any desired manner.
  • a temperature measuring device 13 is arranged, which detects the initial temperature value TA and the control device 8 feeds.
  • the control device 8 therefore takes in this embodiment, the initial temperature value TA from the temperature measuring device 13.
  • the initial enthalpy EA is often not yet clearly determined.
  • the initial enthalpy EA is additionally dependent on at least one initial phase fraction value pA.
  • the initial phase share value pA may be characteristic of the proportion of austenite in the rolling stock 5 or in the considered section 12 of the rolling stock 5.
  • the control unit 8 determines the initial enthalpy EA on the basis of the initial temperature value TA and the initial phase proportion value pA.
  • the initial phase component value pA can in this case be predefined for the control device 8. Alternatively it is possible - see FIG. 1 - That the control device 8 receives the initial phase share value pA from an operator 14 of the cooling section 1 or an external device 15. In the case of the external device 15, this may alternatively be a control device for the upstream hot rolling train or a superordinate control device. Again alternatively, it is possible that the control device 8 automatically determines the initial phase proportion value pA.
  • the control device 8 determines a coolant flow rate K.
  • the control device 8 determines the coolant flow K in such a way that the Walzgutabites 12 of the rolling stock 5 is withdrawn during its passage through the cooling section 1, an amount of heat with the difference of the Conversesenthalpiewerts EA of a predetermined Endenthalpiewert EE corresponds.
  • the coolant flow rate K is here - see FIG. 3 - usually a function of time t. However, it is alternatively possible to determine the coolant flow rate K as a function of the location x in the cooling section 1.
  • the Endenthalpiewert EE is - at least in the rule - assigned a predetermined final temperature value TE (see the following statements in conjunction with FIG. 4 ).
  • the control device 8 determines the coolant flow rate K, however, regardless of whether at the end of the loading of the rolling stock 5 with the coolant K of the Endenthalpiewert EE associated end temperature value TE is reached. It is only considered whether the final enthalpy EE is reached as such.
  • step S4 the control device 8 acts on the rolling stock section 12 during its passage through the cooling section 1 in accordance with the determined coolant flow rate K with the coolant 6.
  • the corresponding pressurization is readily possible because the rolled section 12 is tracked through the cooling section 1 during its passage ,
  • the coolant flow rate K has an earlier period of time 16 and a later period of time 17.
  • the later period 17 in this case immediately follows the earlier period 16.
  • the rolling stock section 12 is actively cooled by the application of the coolant 6.
  • the rolling stock section 12 only cools down passively. An application of the coolant 6 is not carried out during the later period of time 17.
  • the earlier period 16 has a time length t1.
  • the time length t1 is determined to be smaller than a characteristic time constant t2 within which a phase transformation of the rolling stock 5 occurs, for example from austenitic steel to ferritic steel. This ensures that at the end of the earlier period 16, the phase transformation of the rolling stock 5 is done only to a small extent. The extent to which the phase transformation has taken place here depends on the time length t1. Accordingly, it is possible, for example in the case of a rolling stock 5 made of steel, to ensure that at the end of the earlier period 16 the proportion of austenite in the rolling stock 5 is above a desired phase portion or conversely the ferrite portion is below a desired phase portion, etc. In general, it can be achieved at least one phase portion of the rolling stock portion 12 at the end of the earlier period 16 satisfies a predetermined condition.
  • the enthalpy E of the respective rolling stock section 12 decreases.
  • the decrease in the enthalpy E takes place considerably more slowly than in the earlier period of time 16. It can be regarded as substantially constant during the later time interval 17.
  • a further period may follow the later period 17, in which the rolling stock section 12 again the coolant 6 is acted upon.
  • the further period is in FIG. 3 not shown.
  • the end enthalpy value EE must be given. It is possible that the Endenthalpiewert EE of the control device 8 is fixed. However, it is preferable the end enthalpy value EE or the information TE, pE characteristic of the end enthalpy value EE are specified to the control device 8, the control device 8 therefore receives the corresponding values TE, pE. In this case, it is possible for the control device 8 to specify the end enthalpy value EE as such directly. However, it is preferable, accordingly FIG. 4 the step S1 of FIG. 2 Pre-arrange steps S6 and S7. In step S6, the controller receives the final temperature value TE and an end phase component pE.
  • the final temperature value TE and the final phase proportion value pE completely characterize the state of the rolling stock 5. It is therefore possible to determine the end enthalpy value EE in step S7 on the basis of the values TE and pE. If predetermined, the final phase component value pE corresponds to the above-mentioned desired phase component.
  • step S3 of FIG. 2 corresponding FIG. 5 modified.
  • FIG. 5 determines the controller 8 first in step S3, the coolant flow rate K.
  • the control device 8 determines, for example, using a cooling line model known per se (compare, for example, FIG DE 101 29 565 A1 ) - a temperature profile T, which results in the determined in step S3 coolant flow rate K.
  • a corresponding enthalpy curve E could be determined in step S11.
  • the determined course T, E can hereby alternatively be a function of the location x or a function of the time t.
  • the determined course T, E is preferably a function of the time t.
  • step S12 the control device 8 uses the determined temperature or enthalpy curve T, E to determine a location x 'or a point in time t' at which the considered rolling stock section 12 has the end enthalpy value EE.
  • the location x ' is determined here if the determined course T, E is a function of the location x, the time t', if the determined course T, E is a function of time t.
  • step S12 it is possible, in a subsequent to the step S12, in FIG. 5 not shown step to output only the determined location x 'and the determined time t' to the operator 14 and wait for its reaction.
  • This procedure is particularly useful when the predetermined Endenthalpiewert EE is related neither to a predetermined location of the cooling section 1 nor to a predetermined time.
  • the predetermined final enthalpy value EE is related to a predetermined location x "of the cooling section 1 or to a predetermined point in time t".
  • the predetermined time t" may, for example, be a predetermined number of seconds after the rolling stock 12 has reached the cooling section 1.
  • step S13 the control device 8 compares the determined location x 'with the predetermined location x "and the determined time t' with the predetermined time t". Based on the comparison, the controller 8 determines the value of a logical variable OK in step S13.
  • the logical variable OK may take the value "TRUE” if and only if an (possibly signed) deviation of the predetermined location x "from the determined location x 'is within a predetermined tolerance range, analogously it is of course possible to proceed when comparing the determined time t' and the predetermined time t".
  • step S14 the controller 8 checks the value of the logical variable OK. If the logical variable OK is "TRUE", the controller 8 proceeds to step S4. Otherwise, the control device 8 carries out the step S15 in which it modifies the coolant flow rate K.
  • step S16 the control device 8 determines the temperature or enthalpy profile T, E of the respective rolling stock section 12 analogously to step S11. However, in step S16 the control device 8 determines at least one phase-share profile p. When determining the temperature or enthalpy profile T, E, the control device 8 takes into account the determined phase component profile p and vice versa.
  • step S16 is well known to those skilled in the art. Purely by way of example is to the already mentioned DE 101 29 565 A1 directed.
  • the present invention has many advantages. For example, it is very easy to implement because the model of the cooling section 1 can be kept very rudimentary. Solving a complicated heat equation (possibly including a phase transformation equation) is not mandatory. Nevertheless, there are good and above all reproducible control procedures. The operating method always leads to a clear coolant flow rate K and thus solves in particular all problems, which occur in carbon-rich steels in the prior art.
  • a further advantage of the present invention is that the exact location at which the end enthalpy value EE is reached does not necessarily have to be calculated (although this is advantageous). Furthermore, the location does not have to be calculated or fulfilled at which the rolling stock 5 assumes the end temperature value TE associated with the end enthalpy EE. Because after completion of the active cooling (in the earlier period of time 16), the enthalpy E of the considered rolling stock section 12 remains essentially constant, so that the considered rolling stock section 12 reaches the final temperature TE at any time and therefore also at any location.
  • a further advantage of the present invention is that the operator 14 does not have to specify the end enthalpy EE directly but can specify the values end temperature TE and final phase value pE which are familiar to him.
