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, an input side of the roll stand arranged roller table 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 rolling stand arranged roller table such that the initial edge of the strip-shaped rolling stock reaches the nip with an inlet speed.
  • the present invention further relates to a data carrier having 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 relates to a control device for a rolling mill, which is designed, in particular programmed, that the rolling mill can be controlled by it according to such an operating method.
  • the present invention relates to a rolling mill for rolling a strip-shaped rolling stock having a rolling stand with work rolls, a roller arranged on the roll side roller table and a control device, wherein the work rolls form a roll gap and the rolling mill and arranged on the input side of the roll stand of the control device such are controllable, that the work rolls of the rolling stand rotate at a peripheral speed and reaches an initial edge of the strip-shaped rolling stock, the roll gap with an inlet speed.
  • the present invention also relates to a strip-shaped rolling stock having an initial edge with two ends and rolled according to an operating method described above.
  • the rolling stock When rolling strip-shaped rolling stock, the rolling stock is fed to the roll stand usually with an entry speed which is smaller than the peripheral speed of the work rolls of the roll stand. With the arrival of the leading edge of the rolling stock in the nip of the roll gap is closed and rolled the rolled stock.
  • the above operating mode represents the theoretical ideal case in which the initial edge is aligned parallel to the nip and thus enters the nip. In practice, however, it may happen that the two ends of the leading edge run into the nip one after the other, that is to say the initial edge has a skewed position relative to the nip. In this case, there is a so-called diagonal delay, on the one hand leads to an excess width of the rolling stock, on the other hand imprints the rolling stock in the form of a parallelogram. Both effects reduce the so-called spreading, that is the proportion of usable Walzgutvolumen.
  • the guide rulers are made laterally to the strip-shaped rolling stock. They align the strip-shaped rolling stock in such a way that the starting edge is oriented parallel to the nip. Purely by way of example is on the DE 31 16 278 A1 , the EP 0 925 854 A2 and the EP 0 166 981 A1 directed.
  • the alignment of the rolling stock is time-consuming and adversely affects the productivity of the rolling mill. Furthermore, the alignment is particularly poorly possible if the strip-shaped rolling has a large width-length ratio. In addition, there is a risk that the rolling stock between even with proper alignment of the rolling stock the alignment by the guide rulers and the shrinkage in the nip again rotated, so that in spite of the guide rulers an imbalance of the leading edge relative to the nip occurs. 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 the transport rollers of the input side of the rolling mill arranged roller table.
  • the object of the present invention is to improve an operation method for a rolling mill for rolling strip-shaped rolling stock so as to increase productivity and yield.
  • the object is, starting from an operating method of the type mentioned, achieved in that the inlet speed is greater than the peripheral speed and the control device, the peripheral speed and the inlet velocity such a tuned that due to the vote of the peripheral speed and the inlet velocity successive any imbalance the starting edge is at least reduced relative to the nip.
  • this object is also achieved in that a corresponding computer program is stored on the data carrier or that the control device for the rolling mill is designed accordingly, in particular programmed.
  • the object is achieved in that the inlet speed is greater than the peripheral speed and the peripheral speed and the inlet speed of the control device are tuned to one another such that due to the vote of the peripheral speed and the inlet speed to each other a possible skew of the leading edge relative to the nip at least reduced.
  • control means prefferably match the peripheral speed and the lead-in speed such that the strip-shaped rolling rotates around the end first reaching the roll gap in case one of the ends of the leading edge reaches the other end of the leading edge , The gap later reaching the end of the leading edge thus slips on the nip. This procedure is generally preferable.
  • control device the circumferential speed and the lead-in speed tuned to each other so that the strip-shaped rolling in the case that one of the ends of the leading edge before the other of the ends of the leading edge reaches the nip, with the nip first reaching end rebounds from the nip.
  • a particularly accurate coordination of the peripheral speed and the inlet speed to each other is required so that the strip-shaped rolling material 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 control device preferably controls the guide rulers in such a way that they do not touch the strip-shaped rolling stock.
  • the control device preferably accepts characteristic sizes of the strip-shaped rolling stock and of the rolling mill and calculates the circumferential speed and the entry speed on the basis of the characteristic variables in a model.
  • characteristic sizes of the rolling stock come 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 nip and the diameter of the work rolls in question.
  • the control device preferably checks on the basis of the characteristic variables whether an execution condition is met. Only when the execution condition is satisfied, the controller adjusts the peripheral speed and the lead-in speed to each other in accordance with the method described above. On the other hand, if the execution condition is not satisfied, the controller adjusts the peripheral speed and the lead-in speed to each other so that any skew of the leading edge relative to the roll gap is not reduced due to the matching of the peripheral speed and the lead-in speed. A possible skew of the leading edge relative to the nip is thus possibly reduced, but not due to the vote of the peripheral speed and the inlet speed each other. This vote in this case has no influence on reducing the imbalance.
  • the execution condition can take various sizes. Preferably in the execution condition, a length of the strip-shaped rolling stock, a width of the strip-shaped rolling stock, a ratio of length and width of the strip-shaped rolling stock and / or a mass of the strip-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 determines in a step S4 by means of a model 13 in a conventional manner stand settings for the rolling stand 1.
  • the framework settings include in particular a roll gap, g and a peripheral speed vU of the work roll 6 of the rolling stand 1.
  • the roll gap g is a function of the width b, the thickness d, the temperature T, the material composition Z, the desired reduction in the number of stitches ⁇ , the framework stiffness and optionally other 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 nip g and optionally other sizes.
  • steps S5 to S8 the controller 5 checks if various conditions are satisfied. Steps S5 to S8 do not all have to exist. In particular, step S8 could possibly be omitted. However, at least one of the steps S5 to S7 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 distance 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 limit 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.

  • 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.
  • control device 5 carries out steps S9 to S12.
  • 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 greater than the peripheral speed vU of the work rolls 6 of the rolling stand 1 when determined in step S9.

  • step S11 the control device 5 controls the rolling stand 1 in such a way that the framework settings determined in step S4 are set. In particular, the control device 5 controls the roll stand 1 in such a way that the work rolls 6 form the roll gap g and that the work rolls 6 rotate with the peripheral speed vU.
  • step S12 the control device 5 controls the roller table 2 arranged on the input side in such a way that the starting edge 14 of the rolling stock 8 enters the roll gap g at the entry speed vE.
  • the leading edge 14 of the rolled stock 8 has two ends 15, 16.

  • the functional relationship the inlet velocity vE can be determined on the basis of theoretical considerations and / or experimentally.
  • the lead-in speed vE is usually determined by the control device 5 in such a way that the work rolls 6 hold the end 15 which first reaches the roll gap g, but due to the inertia of the rolled stock 8, the rolled 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 procedure is in FIG. 4 schematically indicated by an arrow 17.

  • an orientation of the initial edge 14 relative to the roll gap g is thus achieved at least almost parallel even if this orientation is not achievable by means of the guide rulers 4.
  • the procedure according to the invention that is, the matching of the peripheral speed vU and the entry speed vE in such a way that due to this coordination any skew of the leading edge 14 is at least reduced relative to the nip g, acts particularly well in those cases where the conventional orientation means the guide Rulle 4 fails. Because it works particularly well for short, wide rolled goods 8. It therefore represents an almost ideal supplement to the conventional approach.
