Definitions

  • the invention relates to the rolling of metallurgical products. More specifically, it relates to the regulation of the lateral positioning of metal strips, in particular steel, inside a rolling mill.
  • thermomechanical treatments which will give it its final properties, or undergo a cold rolling which will further reduce its thickness before the completion of the final thermomechanical treatments.
  • tape offsets inside the finishing mill, ie a deviation of the band from its nominal trajectory between two cages. This deviation can reach about thirty mm on either side of this nominal trajectory if nothing is done to compensate for it.
  • Tape offsets can be the cause of incidents such as creasing and rupturing of the belt during rolling, refusal to engage the belt in the roll hold a cage of the finisher, a marking of the rolls of the rolling mill following an impact with the band.
  • These defects may be due to the state of the band itself, or the mechanical disturbances that its treatment in abnormal conditions causes in the operation of the mill.
  • the offset deteriorates the homogeneity of the thickness of the strip at the output of the finishing mill. Finally, it can hinder the successful realization of the winding of the band.
  • band offsets are also at the origin of a defect form called “sword”: a band with this defect, instead of being straight, is bent in a horizontal plane.
  • This defect is due to the existence of a wedge, that is to say a difference in thickness between the two sides of the rolled strip, whose cause may be thermal or mechanical if the heating or rolling were not performed very homogeneously over the entire width of the product.
  • the web offsets can be corrected by means of lateral guides placed between the roll stands, against which the strip comes rubbing when it deviates from its nominal path, and which reorient it towards said nominal path. But when the offset becomes very important (especially at the end of rolling, when the cage located just upstream of the cage considered released the tail of the band and therefore free to pivot to the side of the cage where the air gap cylinders is the largest), the effort that the guides must exert on the band causes friction that deteriorate its banks, sometimes going as far as folding them on themselves or pulling them off. In addition, the guides wear out and need to be replaced periodically.
  • a second method of regulating tape offset is to directly measure the decentering of the tape, as described in DE-3837101 .
  • a device such as a diode camera provided with a reference frame, which determines the absolute position of the strip with respect to the axis of the rolling mill or any other reference position, is placed between two mill stands. According to this indication, one acts if necessary on the difference between the tightenings exerted by the rolls of this cage on both banks of the band. As in the previous method, an increase in clamping on the side where the offset takes place tends to bring the band back to its nominal position. Thus, if we see that the band goes to the left, we modify the tightening to deflect to the right.
  • the object of the invention is to propose a method for rolling a strip in a rolling mill of metal products that makes it possible to effectively control the lateral position of this strip during its rolling and that makes it possible to act more accurately and quickly than existing methods, so as to avoid rolling incidents.
  • An additional advantage would be to obtain a band free of wedge and therefore saber.
  • the invention finally relates to a rolling mill of metal products in the form of strips of the type comprising at least two cages and at least one device for regulating the lateral position of the band of the type according to the invention.
  • This mill may further include at least one device for regulating the position of the tail of the strip according to the invention.
  • the invention consists first of all in controlling the offset of the strip by the imposition of an additional skew on each roll stand between which the strip is in tension, each sway being calculated from representative values of the offset of the band in all inter-cage areas.
  • This process allows to combine efficiency and speed of control, without risk for the band and the mill.
  • This skew value can be adjusted by squeezing the ends of the support rolls more or less.
  • the figure 1 shows a metal strip B being rolled in a rolling mill comprising two cages 1, 2 in which the band B is simultaneously under the influence, for example a finishing mill for the hot rolling of the steel strips.
  • Rolling mills of this type generally have 5, 6 or 7 cages.
  • Each cage 1, 2 comprises, conventionally, two working rolls 1a, 1a ', 2a, 2a' and two support rolls 1b, 1b ', 2b, 2b'.
  • a first sensor 4 (such as a diode camera, or any other apparatus of equivalent function) which acquires a raw signal allowing in fine to determine a value representative of the position of the band B, according to a line transverse to its direction of displacement, between the cage 1 and the cage 2, and a second sensor 5 similar to the previous one, which performs the same operation downstream of the cage 2.
  • a reference position that should normally occupy the band B in the absence of offset.
  • This reference position is generally centered on the theoretical geometric axis of the rolling mill.
  • This reference position 6 is stored in a first processing unit 7 to which are sent the raw signals collected by the sensors 4, 5, and this first processing unit 7 determines the values of the algebraic deviations ⁇ x1 and ⁇ x2 between the positions of the band B recorded respectively by the sensors 4 and 5 and the reference position 6.
  • the processing unit 7 may have to process the raw signal of the sensor to obtain a value representative of the position of the strip (B).
  • the acquisition signal consists of an image of the area covered by the camera.
  • the signal can then be processed using appropriate software to filter the active pixels and to detect the contours of the band B and thus determine its lateral position.
  • the sensors 4 and 5 will preferably be positioned perpendicular to their respective measurement zones and will have to be fixed on independent supports of the rolling mills, presenting the least possible vibration.
  • the sensor 5 can be used both to control the offset of the strip B, but also to measure its width at the exit of the rolling mill.
  • the calculated values of ⁇ x1 and ⁇ x2 are then transmitted to a second processing unit 8 which calculates the additional sway values S1 and S2 to be imposed on the cages 1 and 2.
  • the calculation of S1 and S2 can advantageously be performed by multiplying the values of ⁇ x1 and ⁇ x2 by a gain matrix K.
  • a third processing unit 9 has the function of determining the gain matrix K which will be transmitted to the calculation unit 8.
  • This gain matrix K may in particular be determined by pre-production tests, during which we can model the relations linking the offsets of the strip and the shaking of the support rolls of the rolling mill.
  • This modeling may take into account one or more quantities characteristic of the rolling process, such as the width of the rolls, the rolling force, the rotational speed of the work rolls, etc.
  • the strip to be rolled may also take into account one or more characteristics of the strip to be rolled, such as the thickness of the strip at the entrance of the rolling mill, its hardness, its temperature, etc.
  • the gain matrix K remains constant during the rolling process of a strip B, at least as long as the strip remains under the influence of the first roll stand, only the values representative of the offset of the strip being then modified at each new data acquisition cycle of sensors 4 and 5.
  • a modified gain matrix can be used, taking into account that the strip is no longer under the influence than N-1 cages, if n is the total number of cages.
  • the values of the tightening instructions S1 and S2 can then be transmitted to means 10 for transmitting the instructions that will be imposed on the actuators controlling the dishing of the cages 1 and 2 (which are of a type known in themselves and not shown on the figure 1 ).
  • the method according to the invention makes it possible to control the lateral offsets of the strip with respect to its nominal position and to pass below the threshold of 10 mm, whereas the methods of the prior art do not make it possible to go below the threshold of 20 mm. mm.
  • the regulation cycle may be renewed every 50 or 100 ms, for example, the frequency being preferably chosen to ensure good stability of the regulation.
  • this portion of the strip is pivotable relative to the rolling axis and can even form folds that damage the working rolls of the rolling mill.
  • pseudo-sensors may make it possible to overcome the failure of one or more sensors installed on the line when they fail during a production or when the transmitted signal is unusable because of the very conditions of the process . This may be the case in areas where descaling takes place, generating a dense vapor disrupting the operation of CCD cameras, for example.
  • This use can also limit the number of actual sensors installed on the line, thus reducing the cost of investment and maintenance of the device.
  • the offset of the strip is progressively controlled to reach a stable level, below the threshold of 10 mm, whereas the offset of the strip treated according to the prior art is not not stabilized and consistently exceeds 50 mm.
  • the figure 4 corresponding to the same simulations and resumes in the upper part the five offset curves of the band according to the invention, as a function of time. It also shows in the lower part the curves of additional skewings (DeltaS1 to 5) imposed on each of the five mill stands over time and which made it possible to obtain control of the offsets and the final wedge for the strip treated according to the invention. It is thus seen that by varying these additional skewings as a function of the offset values of each inter-cage, it is possible to successfully rectify significant existing initial offsets due to heterogeneity due to the process. In doing so, one rectifies also the residual wedge which can also be at the origin of the localized offset.
  • the curve presented here represents the evolution of the offset at the level of each inter-cage when the method according to the invention is implemented (curve “with control") or according to the prior art (curve “without control”) . It is also verified that the method according to the invention allows a control of the offset which can thus be lowered from 37 to 10 mm in the final, when measured at 10 meters from the output of the finishing train. The method according to the prior art does not allow him to control the offset which increases steadily. Finally, there is a 63% reduced offset between the strip treated according to the invention and that treated according to the prior art, while the initial values of offset at the exit of the first cage were very close.
  • the invention is applicable, in the first place, to finishing mills for the hot rolling of steel strips. But it can find him applications on other types of rolling mills for metal strips having at least two cages in which the band is simultaneously under the influence. It will thus be possible to implement the invention for cold rolling or skin-pass metal strips, such as steel strips or ferrous or non-ferrous alloys, or even aluminum.
