Definitions
- the invention relates to a method and a rolling train for improving the Ausfäddeins a metal strip whose rolling strip end expires at a rolling speed of a respectively resulting last rolling stand of a multi-stand rolling mill, wherein during rolling between two successive stands for stabilizing the strip run the strip tension is set.
- the rolling speed is adjusted so that a required final rolling temperature of the metal strip, in particular steel strip, is achieved.
- Endwalztemperaturen must be complied with in order to achieve the desired metallurgical properties.
- a reduction of the rolling speed is also undesirable at the end of the belt. Threading out the metal strip at rolling speed, however, is problematic, especially at high rolling speeds and thin end thicknesses.
- the strip tension set between the rolling stands is a decisive factor for stabilizing the strip run.
- the strip tension is reduced shortly before or at the latest with the unthreading from the rolling stand.
- the rolled strip end is then drawn without tension into the next mill stand.
- the belt run is unstable and minor disturbances or deviations can lead to "running" of the rolled strip end in the nip, in which case the metal belt runs out of the center of the mill, producing differential rolling forces and a skewing of the roll gap, which in turn accelerates bleeding.
- causes for this process can be a non-parallel roll gap, temperature differences across the bandwidth, a thickness wedge over the belt width or belt hardness differences.
- the above object is achieved in that shortly before leaving the rolled strip end from a framework, the differential rolling forces generated between the drive side and the operator side are measured separately for each rolling stand, from this pivot value and pivoting direction of the differential rolling force to form a correction value for the employment of Rollers are derived and the employment is corrected.
- the advantage is that the initial situation is improved before the threading out and a bleeding of the rolled strip end is largely avoided.
- the direction and the value of the differential rolling force are determined for this phase, thus calculating a "rolling amount" for the metal strip
- One embodiment provides that the results of the respective measuring step are automatically utilized within the ongoing rolling process from roll stand to roll stand or adaptively from metal roll strip to metal roll strip.
- the advantage is the processing of experience gained.
- One application is that the measurement result for the helmsman in the control center is displayed and the helmsman performs the correction manually during the rolling process.
- a rolling mill for hot rolling a metal strip provides a plurality of rolling mill stands whose work rolls and back-up rolls are each driven on the drive side to maintain a strip tension to stabilize the strip and for a high rolling speed, and measuring devices for measuring the rolling force, respectively are provided on the drive side and on the operator side.
- the stated object is achieved according to the invention in that the rolling forces on the drive side and on the operator side by force gauges shortly before leaving the rolled strip end are determined as Differenzwalzkraft that an evaluation unit for the differential rolling force of the metal strip end and a computer unit for the calculation of a so-called swivel value for the adjustment of the rolls during the passage of the metal band end are provided.
- the advantages here are also those that have already been shown for the process.
- the force measuring devices for the differential rolling force of the metal strip end consist of load cells, which are each arranged below the lower support roller.
- the further design of the measuring devices is designed to the effect that the computer unit a branch for the forwarding of the swivel value is either connected to an automatic for consideration in the current or next metal strip and / or a display of a swivel recommendation for the helmsman.
- the automatic and / or the display is connected to a swivel setpoint comparator and / or a swivel / Istwert toneer and that both to a position control of the hydraulic On the drive side or on a position control of the hydraulic adjustment on the operator side.
- a further embodiment consists in that the position controls are each connected to a cylinder force control for the drive side and the operator side, including a position control for the absolute position setpoint.
- 1A is a stable tape during rolling with tape
- Fig. 1B is an unstable tape when unthreading the tape end, the "runs", in non-parallel and symmetrical employment of
- Fig. 2 is a block diagram for the control of the method
- a stable strip running during rolling of a metal strip 1 is shown, wherein the rolled strip end 1a enters the respective last rolling stand 2 of a hot strip rolling train 3.
- the rolling forces are assumed to act symmetrically with respect to the middle of the framework 2a (FIG. 2).
- the adjustment of the rollers 10, 11 is not parallel, but is wider open on the drive side 4 than on the operator side 5.
- This adjustment leads to an asymmetrical belt tension distribution due to the clamping of the metal strip 1 in the adjacent stands F1 and F3 the strip width, which stabilizes the strip run and prevents the metal strip 1 from extending laterally. fen.
- the tape take-in speeds for the stand F2 on the drive side 4 and the operator side 5 are the same.
- Fig. 1B an unstable tape run during the unthreading of the rolled strip end 1a is shown, wherein after the unthreading of the rolled strip end 1a from the stand F1, the stabilizing strip tension is missing and at different tape feed speeds between the drive side 4 and the operator side 5 of the stand F2 comes.
- the metal strip 1 is drawn in this case at a higher speed on the drive side 4, so that the rolled strip end 1a rotates and extends to the drive side 4 out. Such a process is dangerous and can lead to the described damage.
- the generated rolling forces on the drive side 4 and on the operator side 5 are compared or measured separately for each stand F1, F2, F3, Fn ... and then evaluated. The direction and the value of the differential rolling force are calculated from these measured values.
- the results of the respective measuring step are automatically used within the ongoing rolling process from roll stand (F1) to rolling stand (F2..F3..Fn) or adaptively from metal strip 1 to a new metal strip 1.
- a recovery application is designed such that the measurement result for the helmsman in the control center is displayed on a monitor and the helmsman makes the correction manually during the rolling process.
- FIG. 2 there is shown a rolling stand 2 of the hot strip rolling mill 3 (Fig. 1) whose work rolls 10 and backup rolls 11 are each driven on the drive side 4, the strip train being set to stabilize the strip run and for a high rolling speed. Furthermore, measuring devices for measuring the rolling force on the drive side 4 and on the operator side 5 described below are present.
- the rolling forces are measured in the next rolling stand 2 on the drive side 4 and on the operator side 5 by means of force measuring devices 12 and 13 (for example load cells 17 and 18) and the differential rolling force is determined therefrom; Thereafter, the differential rolling force is determined in an evaluation unit 14 as occurring in an individual case actual differential rolling force of the respective metal strip end 1a.
- a correction value is calculated, which is referred to in the jargon as "swivel value" 16 for the employment of the working and support rollers 10, 11.
- the "swivel value” 16 thus indicates a correction of the setting of the rollers 10, 11 in FIG a rolling stand 2.
- force measuring devices 12, 13 for the differential rolling force of the metal band end 1a come in addition to load cells 17, 18 and other to be arranged in the roll stand Dehn- or compressive stress measuring devices into consideration.
- the helmsman's automatic slew setpoint 23 is routed to a branch 24 in which the values are passed to a hydraulic control / drive side position control (rollers) 25 and to a hydraulic control position control 26 on the operator side 5.
- the swing setpoints 22 and 23 are added to the absolute position setpoint 27 and subtracted.
- the position controls 25, 26 of the hydraulic actuators on the drive side 4 and on the operator side 5 operate with these position setpoints and are connected to a cylinder force control 29 and 30 for the drive side 4 and the operator side 5, respectively.
- Fig. 3 for example, evaluations of the differential force at Walzband- end 1a are shown. After the threading 31 out of the framework FM, an average value 32 of the differential force is formed for a specific time or band length. For the remaining time or length of tape until unthreading 33 from the stand Fi, a relative deviation 34 is then integrated with this mean value. The magnitude of the value thus calculated determines the magnitude of the pan value 16 and the sign the direction of "pan”.
