Definitions
- the invention relates to a method for compensating forces or force components, resulting from horizontal movements of the rolls in roll stands for the hot and cold rolling of flat products, equipped with work rolls and with one or more backup rolls, with hydraulic adjustments and with Force measuring devices on the opposite side of the roll gap and with hydraulic devices for the horizontal displacement of the work rolls.
- Figure 1 of the present application documents describes the basic problem of volatile and stray axial forces, for example on the upper one Back-up roller 1 of a four-high stand.
- the horizontally acting forces T are line-volatile Vectors, that is, they can be shifted along their line of action become. It is therefore irrelevant on which side of the stand the roller is locked.
- Such pairs of forces always arise from the axial force in the contact area to the neighboring roller.
- the individual forces overlap and express themselves in different axial forces on all the rollers involved correspondingly difficult to overlook reaction forces in the roll stands.
- reaction forces show in the roll stands extremely adverse effects.
- the screwing direction of all the rollers involved also changes.
- the rollers are running to the opposite side, which results in a reversal of the axial forces Has.
- the reaction forces in the roll stands change accordingly with the result that the force measuring devices arranged in the stands Report changes that are not related to the actual rolling process stand.
- the result is incorrect reactions of all control loops, which are carried out by the forces measured on the roll stands, such as the flatness control, the automatic calibration for parallel setting of the roll gap, the roll Alignment control to compensate for the effects of an off-center position of the Rolled product and other control loops, depending on the type of roll stand and the Rolled product.
- the invention opens up the possibility of all in one roll stand occurring vagabond forces from horizontal movements of the Rolls to determine continuously and the resulting To compensate for force components in the measured rolling forces. Further Embodiments of the invention are the subject of claims 2 to 7.
- Modern mill stands for cold and hot rolled flat products today almost exclusively with hydraulic adjustments 2 as Thickness control actuator equipped.
- the pitch cylinders the hydraulic adjustment are above the upper one Back-up roll chocks 3 or below the lower back-up roll chocks 4.
- Figure 2 shows an analysis of the forces in a roll stand. Recorded only the forces F from the rolling process and the axial forces T of the rollers. On the representation of balancing forces, Bending and weight forces have been omitted because of the compensation of these forces is known.
- Figure 3 shows the composition of the equation set.
- the derivation of a center deviation is of particular interest X for the position of the resulting rolling force in the roll gap (see Fig. 2).
- This size can also be determined from the six measured values in the Derive rolling operation continuously.
- the equation for the center deviation X is indicated in Fig. 3.
- the size X can be used are used for automatic calibration, i.e. for the automatic Parallel positioning of the two work rolls by changing the rolls the stand is pre-tensioned with rolling rollers without rolling stock and the eccentricity X calculated from the six measured values becomes.
- the Value X regulated to zero with the result of a flawless Parallel position of the upper and lower roller.
- the center deviation X can be used to report such Events and used for a corresponding correction become.
- the automatic calibration and monitoring of the rolling process can also take place in that instead of introducing a center deviation, the measured forces F 1 to F 4 are corrected (compensated) with the help of the calculable reaction forces from the axial forces.
- the equations required for this for the sum of the reaction forces from all the rolls involved are indicated by R 1 to R 4 in FIG. 4.
- the measured values F 1 to F 4 can be used in a manner known per se by forming the difference F 1 minus F 2 or F 3 minus F 4 for the roll calibration and for monitoring the rolling process.
- Figure 4 shows the equation set for the reaction forces from the Axial forces and for the reaction forces from the eccentricity the rolling force.
- FIG. 5 contains a calculation example with assumed roll stand data and rolling data and the data from them using the above Equations calculated roller axial forces and reaction forces.
