Definitions
- the present invention relates to an operating method for a rolling line for rolling a strip, in particular a metal strip,
- the rolling train has a plurality of main rolling stands and a reel downstream of the main rolling stands
- main rolling stands each have work rolls and at least back-up rolls
- a control device of the rolling train is supplied with data of the belt, which determine at least a non-zero total stitch decrease, by which an initial thickness of the belt in the rolling train is to be reduced,
- control device determines single-stitch decreases on the basis of the data supplied to it for the main rolling stands
- control device controls the main rolling stands and the reel in such a way that the strip is rolled in the main rolling stands in accordance with the determined single-stitch decreases and then reeled by the reel,
- the present invention further relates to a rolling mill control program of the type described above, the control program comprising machine code, the execution of which by the control means causes the control means to operate the rolling mill in accordance with an operating method of the above type.
- the present invention relates to a data carrier on which such a control program is stored in machine-readable form.
- the present invention relates to a control device for a rolling train of the type described above, wherein the control device is designed such that it operates the mill train according to an operating method of the type described above.
- the present invention relates to a rolling mill with a plurality of main rolling stands, a main rolling mill downstream reel and a control device, wherein the main rolling stands each have work rolls and backup rolls and the control device is designed such that it operates the rolling mill according to an operating method of the type described above.
- the main rolling mills are usually quarto or sexto scaffolds. This is also the main design case in the context of the present invention. However, other embodiments are possible. Excluded are only pure duo-scaffoldings, which have no further rolls apart from the work rolls.
- a Steckel mill which has two rolling stands, which are preceded by a coiler furnace and a further coiler oven downstream.
- Each of the Waiz scaffolds is designed as a quarto scaffolding. To adjust the temperature of the coiled tape, the tape is rewound with the lowest possible stitch loss - if possible with stitch loss zero.
- the pull in front of the reel should in some cases be as low as possible, since otherwise there is a risk that the individual layers of the reeled coil (coil) stick together.
- the tape Before and behind the last rolling stand where the belt is rolled (ie, in the thickness is reduced), the tape should, however, for reasons of rolling technics have a strip tension.
- one known measure is to provide an S-roll set between the last main roll stand in which the strip is rolled and the reel.
- Another known measure is, for example, to provide a driver instead of the S-roller set.
- the driver can be designed in individual cases as a duo-scaffolding, the tape is not rolled in the duo-scaffolding, but only driven.
- the object of the present invention is to provide articles, by means of which a decoupling of the train in the belt in front of the reel and the train, with which the belt from the last main roll stand in which the strip is rolled, can be achieved.
- the decoupling should - at least in terms of approach - also be feasible in existing systems in which the known measures of the prior art are not feasible.
- the control device determines the single-stitch decreases such that the single-stitch decrease of the main rolling stand immediately preceding the reel is zero. Furthermore, the control device controls the reel main upstream main roll stand such that - based on this main rolling stand - the outlet side train in the band is smaller than the inlet side train, but the band passes through this main rolling mill at least one side without deformation.
- the band may be any bandwidth, for example broadband (bandwidth 1200 mm and more). As a rule, however, it is a narrow band (width 800 mm and less). Often, the band is formed by splitting a broadband (for example, a broadband of 1500 mm width is divided into two narrow bands of 750 mm width each). In particular, in this case, the band often already before rolling in the rolling mill on a spline.
- broadband bandwidth 1200 mm and more
- the band is a narrow band (width 800 mm and less).
- the band is formed by splitting a broadband (for example, a broadband of 1500 mm width is divided into two narrow bands of 750 mm width each). In particular, in this case, the band often already before rolling in the rolling mill on a spline.
- the control device preferably controls the main rolling stand arranged directly upstream of the reel in such a way that the
- the tape should continue to run out of the reel immediately upstream main rolling mill.
- the straight off Running out of this main rolling stand is particularly important here, as long as the reel has not yet reached the band.
- the correct running direction of the belt can also be achieved by pivoting the work rolls of the relevant main rolling stand counter to one another or by working them in a wedge profile.
- the band is often made of steel. Steel can alternatively be cold rolled or hot rolled. In some cases, the present invention can be applied to hot rolling. As a rule, however, the strip is cold rolled in the rolling mill.
- the number of main rolling stands is in principle arbitrary. At least it is two. As a rule, it is between four and seven.
- the control device preferably controls the main rolling stand, which is directly preceded by the reel, with rolling force control.
- the control device determines a nominal rolling force of this main rolling stand such that the strip passes through this main rolling stand without deformation.
- FIG. 1 shows a rolling mill with main rolling stands, a reel and a control device
- FIG. 2 shows a main rolling stand and a strip in the strip running direction
- a rolling mill according to the invention has a plurality of main rolling stands 1, 1 ', a reel 2 and a control unit. direction 3.
- the main rolling stands 1, 1 ' are successively passed through by a belt 4 and then reeled by the reel 2.
- the control device 3 controls the main rolling stands 1, 1 'and the reel.
- the number of main rolling stands 1, 1 ' is usually four to seven. At least it is two.
- the main rolling stands 1, 1 ' are generally formed (see also FIG. 1) as quarto stands. So they each have work rolls 5, 5 'and back-up rolls 6, 6'. Alternatively, they may additionally have additional rollers, for example in the case of training as a six-high scaffolding intermediate rolls.
- the reel 2 is the last main rolling stand 1 'immediately downstream.
- the term "immediately downstream” in this case means that there is no element between the last main rolling stand 1 'and the reel 2, with which a train Z prevailing in the belt 4 can be influenced to a significant degree Reel 2, however, one or more pulleys 7 may be arranged.
- the last main rolling stand 1 ' is of particular importance in the context of the present invention. For this reason, it was - in contrast to the other main rolling stands 1 - provided with its own reference numeral, namely the reference numeral 1 '. Other sizes, insofar as they relate specifically to the last main rolling stand 1 ', are subsequently provided with an apostrophe. A further significance is not the distinction.
- the rolled strip 4 in the rolling train is usually a metal strip, for example a steel strip.
- the band 4 may be a band 4 of any width b, for example broadband, ie a band 4 having a bandwidth b of at least 1200 mm.
- the band 4 according to FIG. 2 is a narrow band. band whose maximum width b is 800 mm. In most cases, the bandwidth b is even less than 600 mm or less than 700 mm.
- the band 4 may have a spline already before rolling in the rolling mill. It is thus possible that the band 4 on one side has a larger band thickness dl than on the other side, where it has a smaller band thickness d2.
- the illustration in FIG. 2 is exaggerated here.
- the band 4 is cold rolled in the rolling mill usually. In some cases, however, hot rolling is also possible.
- control device 3 controls, as already mentioned, the main rolling stands 1, 1 'and the reel 2.
- control is to be understood in a comprehensive sense, ie in the sense of influencing the operating state of the rolling train. not to be understood as opposed to the term “rules”.
- the controller 3 comprises basic automation (i.e., simple controllers for, for example, roller speeds, nips, rolling forces, etc.) and a superimposed control system. In the context of the present invention, it depends on the superimposed control system.
- the control device 3 is usually designed as a software programmable device. It is fed to a control program 8.
- the feeding of the control program 8 can take place, for example, via a network connection (LAN, Internet,...) Or via a data carrier 9 on which the control program 8 is stored.
- a disk 9 for example, a CD-ROM (see FIG 1), a USB memory stick or a memory card in question.
- the control program 8 comprises machine code 10, ie program instructions which can be executed directly and directly by the control device 3.
- the control program 8 can - at- For example, be called by an operator 11 of the rolling mill - in the usual way (mouse click, etc.). Due to the call, it is executed by the controller 3.
- the execution of the control program 8 by the control device 3 causes the control device 3 to operate the rolling mill in accordance with an operating method which will be explained in more detail below in conjunction with FIG.
- the control device 3 accepts data of the belt 4 in a step S 1, which data are fed to the control device 3.
- the data include, for example, information on the bandwidth b, the initial strip thickness d-in, a target final thickness d-out, an initial temperature T and a chemical composition of the strip 4.
- the data supplied to the control device 3 implicitly or explicitly imposes an overall stitch decrease A by which the initial thickness d-in of the strip 4 in the rolling train is to be reduced.
- the total decrease A is - of course - greater than zero.
- the total stitch loss A, the initial strip thickness d-in, and the target final thickness d-out are here according to the relationship
- the control device 3 uses the data d-in, d-out, b, T supplied to it for the main rolling stands 1, 1 'to determine single-stitch decreases a, a'.
- the single stitch decreases a, a 'are defined analogously to the total stitch decrease A, but the input and output thicknesses refer to the respective main roll stand 1, 1'.
- the single stitch decreases a, a 'are of course determined by the control device 3 in the context of step S2 such that they correspond in total to the total stitch decrease A.
- the control device 3 sets the single-stitch decrease a 'for the last main rolling stand 1' to the value zero. This is in contrast to what is known as skin pass mills. In the case of skin pass mills, the single-cut decrease a 'of the last main rolling stand 1' is relatively small (for example, only 1%), but greater than zero.
- the other single-stitch decreases a determines the control device 3 in the context of step S2 as needed. In principle, the determination of the other single-stitch decreases a such as if the last main roll stand 1 'simply would not exist.
- step S2 is always and always carried out as described above. It may alternatively be modified in that the control device 3 first tries to distribute the total stitch decrease A to the main rolling stands 1 with the exception of the last main rolling stand 1 '. If this is possible, step S2 is executed as explained above. Otherwise, the band 4 can only be properly rolled if the single stitch decrease a 'of the last roll stand 1' is greater than zero. In such a case, either the single-stitch decrease a 'may be chosen as small as possible or determined in the usual way.
- a step S3 the control device 3 controls the main rolling stands 1, 1 'and the reel 2.
- the control takes place in such a way that the strip 4 is rolled in the main rolling stands 1, 1 'in accordance with the determined single-stitch decreases a, a' and then reeled up by the reel 2.
- the control device 3 controls the last main rolling stand 1 'in such a way that, with reference to the last main rolling stand 1', the outlet-side pull Za in the strip 4 is smaller than the inlet-side pull Ze.
- the drive continues to be such that the belt 4 passes through the last main rolling stand 1 'at least one side without deformation.
- the control device 3 5-to actuate the work rolls 5 'of the last main rolling stand 1' by means of the control device 3 in such a way that the work rolls 5 'are pivoted relative to one another as viewed in the strip running direction x.
- the work rolls 5 'seen in the strip thickness direction can be employed in a spline (see FIG 4).
- a rolling force F' which is applied to the last roll stand 1 'by the strip 4, must not be too large.
- the rolling force F 'must therefore be below an upper limit S.
- the rolling force F 'must lie above a lower barrier S'.
- the control device 3 therefore preferably controls the last rolling stand 1 'with rolling force control.
- the target rolling force F '* for the last main rolling stand 1' is determined here by the control device 3 such that it lies between the lower barrier S 'and the upper barrier S.
- the belt 4 is rolled on the one hand in the main rolling stands 1, 1 'and on the other hand is uncoiled by the reel 2.
- start of the rolling process refers to the time until the time when the reel 2 grips the band 4.
- the control device 3 controls the last main rolling stand 1 'accordingly.
- Control device 3 the last main rolling mill 1 'drive such that the work rolls 5' of this main rolling stand 1 'seen in the tape running direction x are pivoted against each other.
- the control device 3 it is possible for the control device 3 to actuate the last main rolling stand 1 'in such a way that the work rolls 5' of this main rolling stand 1 'form a wedge profile viewed in the strip thickness direction.
- the embodiments according to the invention have many advantages.
