Definitions
- the present invention relates to an operation method for a rolling mill for rolling a strip-shaped rolling stock having an initial edge with two ends.
- the rolling mill has a roll stand with work rolls, a roller table arranged on the input side of the Waiz frame and a control device.
- the work rolls form a nip.
- the controller controls the rolling stand so that the work rolls of the rolling stand rotate at a peripheral speed.
- the control device further controls the input side of the roll stand arranged roller table such that the on ⁇ catching edge of the strip-shaped rolling stock reaches the nip with an inlet speed.
- the present invention further relates to a data carrier with a computer program stored on the data carrier for carrying out such an operating method when the computer program is executed by a control device for a rolling mill. Also, the present invention He ⁇ a control device for a rolling mill, which is designed in such a way is in particular programmed to the
- Rolling mill is controlled by it according to such an operating method.
- the present invention relates to a rolling mill for WAI zen a ribbon-shaped rolled stock, which beitswalzen a rolling stand with Ar ⁇ , an input side of the rolling mill being arrange ⁇ th roller table and control means, wherein the work rolls forming a roll gap and the roll stand and the input side of the rolling stand arranged roller table can be controlled by the control device such that the work rolls of the rolling stand rotate at a peripheral speed and an initial edge of the strip-shaped rolling ⁇ good reaches the nip with an inlet speed.
- the present invention also relates to a band- ⁇ -shaped rolling stock, which has a leading edge with two ends ⁇ and in accordance with an operating method described above was rolled.
- the rolling stock When rolling strip-shaped rolling the rolling stock is guided in the roll stand usually with a gate velocity to ⁇ which is smaller than the circumferential speed of the work rolls of the rolling mill. As the initial edge of the rolling stock enters the nip, the nip is closed and the rolled stock is rolled.
- the above operating mode represents the theoretical ideal case in which the starting edge is aligned parallel to the roll gap and thus also enters the roll gap.
- the guide rulers are ⁇ employed the side of the strip-shaped rolling stock. They rich ⁇ th shaped rolling stock made such that the leading edge is oriented parallel to the nip.
- the alignment of the rolling stock is time-consuming and adversely affects the productivity of the rolling mill. Furthermore, the off ⁇ possible direction especially poorly when the band-shaped rolling a large width to length ratio has up. In addition, even when properly from ⁇ direction of the rolled material is a risk that the rolling stock itself rule Zvi ⁇ aligning rotated again by the guide bars and running into the nip so that in spite of the Guide rulers a skew of the leading edge occurs relative to the nip. The risk of twisting of the rolling stock is greater, the greater the ratio of width to length of the strip-shaped rolling stock and the smaller the ratio of length of the strip-shaped rolling stock to distance of
- Transport rollers of the input side of the rolling mill arrange ⁇ th roller table is.
- the object of the present invention is to improve a rolling mill operating method for rolling strip-shaped rolling so as to increase productivity and yield.
- the object is, starting from an operating method of the type mentioned, achieved in that the Einlaufge ⁇ speed is greater than the peripheral speed and the control device, the peripheral speed and the on ⁇ running speed tuned to each other that due to the vote of the peripheral speed and the on - Running speed on each possible skew of the leading edge relative to the nip is at least reduced.
- the object is also solves ge ⁇ that is program stored on the data carrier a corresponding computer or that the control device for the rolling mill is designed in accordance with is programmed in particular per ⁇ .
- the object is achieved in that the inlet speed is greater than the peripheral speed and the peripheral speed and the Einlaufgeschwin ⁇ speed of the control device are tuned to each other such that due to the vote of the peripheral speed and the inlet speed successive an imbalance of Beginning edge relative to the nip ⁇ at least reduced.
- the task for the strip-shaped rolling stock is achieved in that it was rolled during at least one rolling operation according to a Be ⁇ driving method described above.
- control means controls the supervisesge ⁇ speed and aufeinan the feeding speed so ⁇ adapts that the strip-shaped rolling stock, in the case that one of the ends of the leading edge in front of the other of the ends of the leading edge reaches to the nip, around the the roll gap ⁇ first reach the end turns. The gap later reaching the end of the leading edge thus slips on the rolling gap ⁇ .
- This procedure is generally preferable.
- the peripheral speed and the inlet ⁇ speed so coordinated that the strip ⁇ shaped rolling in the case that one of the ends of the ⁇ catching edge before the other of the ends of the leading edge reaches the nip, with the nip first reaching end of the nip bounces.
- a special ⁇ DERS exact synchronization of the peripheral speed and the feeding speed is required on each other, so that the shaped rolling stock does not rebound too far.
- the operating method according to the invention can also be used in particular in existing rolling mills, that is to say in rolling mills which have the guiding rulers mentioned above. These guide rulers are usually adjustable to the rolling stock.
- the controller controls the material guides vorzugswei ⁇ se in such a way that they do not berüh ⁇ ren shaped rolling stock.
- the controller accepts characteristic variables of band-shaped material to be rolled and the rolling mill opposite and calculated from the characteristic parameters in a model of the peripheral speed and the Einlaufgeschwindig ⁇ ness.
- characteristic sizes of the rolling stock in particular in particular the length, the width, the thickness and the mass of the rolling stock in question.
- the characteristic variables of the rolling mill are in particular the distance of individual transport rollers of the roller table, the roll gap and the diameter of the work rolls in question.
- the controller checks on the basis of characte ristic ⁇ sizes, whether an execution condition is satisfied. Only if the execution condition is met, the control device adjusts the peripheral speed and the inlet ⁇ speed according to the above-described method from each other. Conversely, if the performance condition is not met, the controller adjusts the order ⁇ peripheral speed and the feeding speed to one another such effect that any angled position of the leading edge does not aufeinan relative to the roll gap due to the synchronization of the peripheral speed and the feeding speed ⁇ is reduced. A possible skew of the initial edge relative to the nip is thus possibly reduced, but not due to the vote of personnelsge ⁇ speed and the inlet speed to each other. In this case, this vote has no influence on the reduction of the sliding surface.
- the execution condition can take various sizes. Preferably go in the execution condition a length of the band-shaped rolling stock, a width of the strip-shaped rolling stock, a ratio of length and width of a bandförmi ⁇ gen rolling stock and / or mass of the band-shaped rolling stock.
- the roller table arranged on the input side roller table can have guide rulers, which can be adjusted laterally against the strip-shaped rolling stock. If the execution condition is not met, the control device preferably adjusts the guide rulers so that they touch the strip-shaped rolling stock.
- the strip-shaped rolling stock is thus in this case either according to the invention Method or according to the conventional method (ie, by the guide rulers) aligned.

- the control device 5 is supplied via a data carrier 10, on which a computer program 11 is stored, this computer program 11.
- the control device 5 takes over the computer program 11 and stores it in an internal memory 12.
- the control device 5 is programmed (or formed more generally) in such a way that when the com computer program 11, the rolling mill operates according to an operating method is explained in more detail he ⁇ below in connection with FIG. 3
- the control device 5 initially accepts characteristic sizes of the rolling stock 8 in a step S1.
- the characteristic variables of the rolling stock 8 comprise, in particular its length 1, a width b, d the thickness thereof, m the ⁇ sen mass whose temperature T and its material com- position Z. If desired, the control device 5 as part of step Sl also other sizes of the rolled material 8 are supplied.
- control device 5 also accepts characteristic variables of the rolling mill.
- the characte ristic ⁇ sizes of the rolling mill include in particular the diameter of the working rolls 6 and the distance a of the transport rollers 9 from each other.
- characteristic quantities of the desired rolling operation takes entge ⁇ gene.
- the characteristic quantities of the desired rolling operation include, in particular a reduction per pass and a ⁇ ge ⁇ desired rolling speed Vw.
- ⁇ the pass reduction may be alternatively required as absolute or relative pass reduction specified differently.
- the control device 5 determines in a step S4 by means of a model 13 in known Wei ⁇ se framework settings for the roll stand 1.
- the framework settings include in particular a roll gap g and a peripheral speed vU of the work rolls 6 of roll stand 1.
- the roll gap g is a function of the width b
- d is the thickness, the temperature T, of the material composition Z, the desired pass reduction ⁇ , the mill rigidity and, where appropriate, further ⁇ variables.
- the peripheral speed vU of the work rolls 6 is in particular a function of the thickness d, the reduction ⁇ , the rolling speed vW, the rolling ⁇ gap g and optionally other sizes.
- steps S5 to S8 the control device 5 checks whether various conditions are met. Steps S5 to S8 do not all have to exist. In particular, step S8 could possibly be omitted. At least one of Schrit ⁇ te S5 to S7 but must be present. The most important step should probably be step S5.
- step S5 the control device 5 first checks whether the length l of the rolling stock 8 is below a limit length L.
- the limit length L is preferably a multiple of the Ab ⁇ States a of the transport rollers 9 from each other, for example, five to ten times.
- step S6 the control device 5 checks whether the width b of the rolling stock 8 exceeds a limiting width B.
- the border width B is preferably also a multiple of the distance a of the transport rollers 9 from each other.
- step S7 the control device 5 checks whether the ratio of width b to length 1 of the rolling stock 8 is above a threshold S.
- the threshold S usually has a value that is greater than two. In general, he is even larger than three.
- step S8 the control device 5 checks whether the mass m of the rolling stock 8 is below a limit mass M.
- steps S5 to S8 can in principle be linked together in any desired manner, for example by means of a logical OR operation. According to FIG. 3, they are AND-linked.
- step S9 the control device 5 in the model 13 determines an intake speed vE.
- the entry speed vE is the speed at which an initial edge 14 of the Walzguts 8 reaches the nip g. It is, if it is determined in step S9 is greater than the personnelsgeschwindig ⁇ ness vU of the work rolls of the rolling mill 6. 1
- step S the control device 5, the Materialssli ⁇ neale 4 from the rolled stock. 8 It sets the guide ruler 4 so that they do not touch the rolling stock 8.
- step S the control device 5 controls the rolling stand 1 in such a way that the stand settings determined in step S 4 are set. Specifically, the control device 5 controls ⁇ the rolling stand 1 is therefore such that the Ar ⁇ beitswalzen 6 form the nip and that the g Arthurwal ⁇ zen 6 rotate with the peripheral speed vU.
- step S12 the controller 5 controls the input-side roller table 2 in such a way that the initial edge 14 of the rolled ⁇ 8 g enters into the nip with the feeding speed vE.
- the top edge 14 of the rolling stock on 8 two En ⁇ 15, 16th Ideally, the top edge is aligned parallel to the nip 14 g and runs as in the roller gap G ⁇ a. In this case, both ends 15, 16 reach the roll gap g at the same time. In practice - see Figures 4 and 5 - but usually reaches one of the ends 15, 16 of at ⁇ catch edge 14, here the end 15, before the other of the ends 15, 16 of the leading edge 14, here the end 16, the roll gap g.
- the starting edge 14 therefore has a skew relative to the nip g.
- the control determined device 5 the feeding speed vE as part of step S9 in such a way that due to the tuning of the Click ⁇ peripheral speed VU and the gate velocity vE such a skew of the leading edge 14 re ⁇ tively g to the nip at least reduced.
- the entry speed vE is a function which can depend on the length 1, the width b, the thickness d and the mass m of the rolling stock 8, the peripheral speed vU, the distance a and possibly also other variables.
- the functional attraction of feeding speed vE can theoretically due ⁇ genetic considerations and / or determined experimentally.
- the lead-in speed vE is usually determined by the control device 5 such that the work rolls 6 hold the first end 15 reaching the roll gap g, but due to the inertia of the rolled stock 8, the rolling stock 8 slips onto the work rolls 6 on the transport rolls 9 ,
- the control device 5 adjusts the peripheral speed vU and the entry speed vE to one another in such a way that the strip-shaped rolling stock 8 in this case rotates about the end 15 which first reaches the roll gap g.
- This pre ⁇ hens as is schematically indicated in FIG 4 by an arrow 17th
- the vote of the peripheral speed vU and the inlet speed vE aufeinan ⁇ of the control device 5 is made such that the strip-shaped rolling 8 in the case that one of the ends 15, 16 of the leading edge 14 (here the end 15) before the other of the ends 15, 16 of the leading edge 14 (here the end 16) reaches the roll gap g, with the first nip gap g rebounding ⁇ rebounding 15 rebounds from the nip g.
- This is indicated schematically in FIG. 5 by arrows 18, 19, the arrow 18 being larger than the arrow 19.
- control device 5 executes steps S13 and S14 instead of steps S9 and S10.
- step S13 the control device 5 - analogous to step S9 - determines the inlet velocity vE. It determines the feeding speed vE within the framework of the step S13 but such that any angled position of the leading edge 14 rela- tively to the roll gap g is not because of the synchronization of peripheral speed vU and feeding speed vE aufein ⁇ is on the other reduced.
- the inlet velocity vE can therefore be smaller than the circumferential velocity vU, in particular. However, it can still be a function of the length 1, the width b, the mass m, the thickness d, the peripheral speed vU and possibly other variables such as the distance a of the transport rollers 9 from each other.
- step S14 the controller 5 to the Materialssli ⁇ neale 4 of the rolling stock. 8 It sets the guide rulers 4 so that they touch the strip-shaped rolling stock 8. In this case, therefore, the alignment of the rolling stock 8 takes place through the guide rails 4.
