Definitions
- the invention relates to a device and a method for rolling sheet metal and strip on a roll stand, in which the upper and lower work rolls, possibly in pairs together with the support rolls assigned to them, by opposing horizontal adjustment of the chocks stored within the stand window from the common vertical plane out about a common vertical axis that intersects the long centers of the rollers can be pivoted into positions in which the vertical planes running through the roller axes of the working or optionally working and support rollers intersect at a predetermined angle
- the object of the present invention is then to achieve a central pass of the rolling stock in the rolling line in a rolling mill of the generic type, without resulting in faulty strip runs
- the upper and lower work rolls possibly in pairs with their support rolls, based on the common, the starting plane intersecting the roller axes are each pivoted by different angular amounts
- the advantage of the present invention is to be seen first of all that incorrect rolling of the rolling stock is prevented by a controllable actuator directly in the respective stand. Correction by a subsequent stand, as is provided by the prior art, is not necessary, so that the present invention for that too last stand of a tandem mill, but can also be used advantageously for individual stands in particular. A particular importance of the invention is also seen in the application for rolling extremely thin strips, because the transverse course of the strips can be prevented as soon as they are created
- the respective pair of rolls consisting of work rolls or to pivot together from work and support rolls around a vertical axis, in order to thus change the angular amount for correcting the strip path.
- the core of the method according to the invention is therefore the setting of different adjustment angles for the upper and lower roll sets or the upper and lower work roll, based on a vertical plane transverse to the rolling direction
- a rolling stand for carrying out the method according to the invention is characterized in that the displacement drives for the chocks of the work roll, each receiving one end of the roll, and possibly of the support roll displaceable in pairs with respect to the upper and lower work roll and / or work and support roll, can be actuated independently of one another
- Proposal of the invention means that each work roll or each work roll can be pivoted together with the support roll assigned to it independently of the other work roll. The pivoting about the common vertical pivot axis intersecting the roll center, however, presupposes that the
- Displacement drives the chocks provided at both ends of a roller are shifted by the same amount, but with respect to the other roller, the chocks of the other roller are adjusted by different displacement paths
- Rolling stand measuring devices are provided for detecting the faulty strip course, the measuring signal of which is converted in a computing unit, taking into account stored target values, into a signal for actuating the displacement drives in each case at least one of the rolls
- the lateral belt path is regulated by the fact that the displacement drive of at least one of the rollers is actuated in such a way that the angle adjustment of this roller is set differently with respect to a vertical plane running transverse to the roller direction.
- known bending means can be provided with which the profile of the rolling stock can be additionally influenced
- Fig. 1 is a schematic plan view of a three-step rolling mill with the longitudinally cut roll stands and
- Fig. 2 shows a rolling mill according to the invention in a schematic enlarged view
- Figure 1 is a schematic plan view of a three-step rolling mill with the longitudinally cut rolling stands 1, 2, 3 the setting according to the invention
- both work rolls 4, 5 are each pivoted 0.6 ° out of the vertical plane 6 shown in the upper roll stand 1, specifically about a vertical axis 9 which runs through the longitudinal center of the two work rolls.
- the intersecting vertical roller planes 10, 11 form an angle of 0.12 ° with each other and an angle of 0.6 ° to the vertical plane 6.
- the crossing of the work rolls 4, 5 causes a convex strip cross-sectional profile 7, but at the same time also a strip path 8, which is deflected laterally out of the rolling direction 12.
- This band course 8 is harmful and must therefore be corrected.
- the upper work roll 4 is pivoted to the left by an angular amount of 0.9 ° with respect to the common vertical plane 6, while the lower work roll 5 is pivoted to the right by an amount of 0.3 ° becomes.
- the sum of both angles is 1, 2 °, so as with the middle roll stand, whereby due to the different pivoting of the
- cassettes 16, 17 which can be displaced by means of the displacement drives 13, 14 in the form of piston-cylinder units and can thereby be pivoted about the common central axis 9.
