Definitions
- the invention relates to a rolling device according to the preamble of claim 1 and a method for its operation according to claim 5.
- Rollers are well known in the art.
- such rolling devices are known in which a pair of work rolls are acted upon by at least two opposite the work rolls larger support rollers for receiving the rolling forces.
- the flatness of the rolling stock may vary, whereby a material backlog can arise immediately before the nip between the work rolls. If the material backlog can not be compensated in time and precisely enough, unevenness in the flatness of the rolled material will result, which leads to a loss in quality of the rolling stock and which may make the rolling stock completely unsuitable for some applications.
- DE 27 43 130 discloses a rolling device with thickness measuring devices in front of and behind the nip, so that a predetermined thickness tolerance can be achieved. However, so that the effect of the material backlog can not be resolved, because the sensors in turn is located far away from the nip. In addition, localized thickness variation may be meaningful only in conjunction with an accurate profile reference. An unplanarity can not be sufficiently qualified.
- the object is achieved with respect to the rolling device, by a rolling device according to the features of claim 1 with rolling device with at least two work rolls and a nip between the work rolls for performing and rolling a rolling stock, such as a belt preferably made of metal, and optionally an arrangement of Support rollers, further comprising at least one measuring device is provided for measuring a backlog of the rolling stock of the rolling stock in front of the nip, further wherein a control or regulating unit is provided, which actuates actuators for adjusting the flatness of the rolling stock due to the signals of the measuring device.
- a flatness measuring device which likewise provides signals for the control or regulating unit, whereupon, in response to the signals of the measuring device and the flatness measuring device, the actuators for adjusting the flatness of the Walzguts drives.
- an actuator for adjusting the flatness of the rolling stock comprises an actuator for adjusting the inclination of the work rolls and / or the intermediate rolls and / or the backup rolls, the bending of the work rolls and / or the intermediate rolls, and / or the backup rolls which is axial displacement of the work rolls and / or the intermediate rolls, for example in the context of a Continuously Variable Crown (CVC) shift, a minimum quantity lubrication and / or a temperature control or temperature control of the belt and / or the work rolls.
- CVC Continuously Variable Crown
- the at least one measuring device for measuring a backlog of the rolling material of the rolling stock in front of the roll gap is an optically or mechanically measuring measuring device.
- the object with respect to the method is achieved by a method for operating a rolling device according to claim 5. The advantages of this method correspond to the advantages stated above with respect to the device.
- the at least one measuring device for measuring a backlog of the rolling material of the rolling stock before the roll gap detects the backlog optically or mechanically.
- Figure 1 is a schematic representation of a rolling device with measuring device.
- a rolling device 1 shows schematically a rolling device 1 with two work rolls 2,3 between which a roll gap 4 is provided and between which a rolling stock 5, such as a belt 6 or metal strip, in particular a steel strip is rolled.
- the work rolls 2, 3 are advantageously loaded in a known manner with support rolls 7, 8 in each case. If the strip 6 as rolling passes in the rolling direction 9 through the working gap 4, a material backlog 10 can occur in the immediate vicinity of the roll gap 4 and in the rolling direction in front of the roll gap 4, which leads to deformations of the rolling stock and thus causes flatness deficits of the rolling stock.
- the backlog arises because at least temporarily more material of the rolling stock per unit time before the nip is transported or pressed than can be rolled during the same time unit and can pass through the nip.
- the backwater is created in areas of local belt voltage drop.
- the device 1 further comprises at least one measuring device 11 or at least one sensor which detects a material backlog 10 at the strip inlet of the roll gap.
- This at least one measuring device 11 is a preferably mechanically measuring or non-contact measuring sensor.
- the non-contact measuring sensor is preferably an optically measuring sensor, which optically recognizes the material backlog 10, which in part is only local.
- the backlog in the form of a local overreduction is visible as a drop in the belt tension in these areas to ripple in front of the nip and visible to the measuring device.
- the sensor or the measuring device 11 is arranged on the input side of the roll gap 4 and preferably detects near the roll gap 4 or in the immediate vicinity of the roll gap 4, the material backlog 10, for example, due to a surface variation of the rolling stock 5, such as the belt 6.
- the sensor is so stated that the measurement of the material backpressure in front of the nip is made in a range of about one meter or less in front of the nip, preferably detecting a measurement of the material backlog in the range of about 200 to 300 mm in front of the nip.
- a flatness measuring device such as a flatness measuring roller 12
- a flatness measuring device which detects the flatness of the belt 6 behind the rolling device 1 with the nip 4.
- the signals of the backflow measurement sensor 11 or the signals of the backflow measurement sensor 11 and the flatness measurement device 12 are fed to a control or regulating unit 13 which, on the basis of the available input data, outputs at least one drive signal 14 or a plurality of drive signals for the actuators 15, 16, 17, 18 and 19, such as flatness actuators, of the rolling arrangement, by means of which the actuators 15, 16 , 17,18 and 19 are controlled to control or control the flatness of the rolling stock.
- the signals from the sensors 10 and 11 are fed to the control or regulation unit 13, wherein a weighting can be carried out between the two sensors or their signals, each of which can be acted upon by a preselectable additive addend and a multiplicative factor and / or individually or both signals can be acted upon by delay elements and / or be acted upon by filters.
- a stable strip running under stable rolling conditions can be achieved, with prompt engagement can be made when a backwater 10 of the rolling material is detected in front of the nip 4.
- a pass of 300 mm can be made in 0.3 seconds, so that a quick response in the range of tenths of a second or less is advantageous in order to control the material backlog before the Waisz gap.
- a quick control intervention or control intervention in the case of a changing band profile, with a changed flatness, for example at the beginning of the band, at the band end or in the case of a weld seam can be undertaken.
- the actuators 15 to 19 are preferably actuators for adjusting the angle of the work rolls 2, 3 and / or the support rolls 7, 8, the bend of the work rolls. beitswalzen 2,3 and / or intermediate rollers (sexto-type) and / or the back-up rollers 7,8, the axial displacement of the work rolls 2,3 and / or intermediate rolls (sexto-type) in the context of a so-called Continuously Variable Crown (CVC) - Displacement, a minimum quantity lubrication or a temperature control or temperature control of the belt and / or the work rolls.
- CVC Continuously Variable Crown
