Definitions
- the invention relates to multi-roll stands for rolling strip-shaped rolling stock, with a lower and an upper Work roll, backup rolls assigned to the work rolls, Roll bending devices for the work rolls as well Devices for adjusting and balancing the backup rolls, the lower and the upper work roll of the roll stand in two lower and two upper back-up rolls are mounted, the symmetrical to the vertical roll axis plane of the work rolls arranged and in pairs in lower and upper Back-up roller chocks are stored.
- a multi-roll stand of this type is from the JP 10 263 632 A known.
- DE 195 18 144 A1 describes a rolling mill Work rolls, which due to the small roll diameter the Problems of horizontal deflection during the rolling process itself recover.
- the top and bottom of this mill are Work roll each generated by the rolling force Circumferential force of the rolling moments introduced into the backup rolls driven.
- the multi-roll stand described are the work rolls by means of Support roller pairs supported. The two lines of contact work rolls led to the backup rolls allow only one restricted adjustment range of the work roll bending.
- DE 22 06 912 C3 is a roll stand with two Work rolls and can be moved in opposite directions on the bandwidth adjustable intermediate rolls known, each in a Backup roller pair are rotatably positioned, the Work rolls for better adaptation to the strip profile with one Roll bending device are equipped.
- Disadvantage for the Flexible rolling are used in this type of rolling mill also the horizontal deflection of the work rolls, which the Rolling force transmitting circumferential force and the relatively large Masses in terms of a required high Acceleration property of the roll adjustment.
- Multi-roll stands according to EP 0 665 067 B1 have Work rolls with the smallest diameter and sufficient Support, however, require a not insignificant Effort to compensate for the deflection of the Roll set such as support rollers and bending devices and are limited with regard to the achievable strip thickness reduction.
- the invention has for its object a roll stand for to develop flexible rolls of strip material.
- the roll stand 1 according to FIGS. 1-3 for flexible rolling of Strip material 2 has a lower and an upper work roll 3, 4 to avoid horizontal deflection in two lower and two upper support rollers 5, 6; 7, 8 are mounted, the symmetrical to the vertical roller axis plane 9-9 of Work rolls 3,4 arranged and in storage units 10a, 10b, 11a, 11b displaceable in the axial direction in the lower and upper Backing roll chocks 10, 11 are mounted in the two Roll stands 12, 13 of the roll stand 1 vertically and horizontally are guided.
- the support rollers 5,6; 7,8 are through to the Backing roll chocks 10, 11 attached motors 14 driven.
- the lower and the upper work roll 3, 4 are in the lower one and upper work roll chocks 15,16 stored in the two roller stands 12, 13 guided and vertically displaceable can be acted upon by work roll bending devices 17, 18.
- the balance of the support rollers 5.6; 7.8 is done by on the lower and upper backup roll chocks 10,11 Acting balancing devices 19.20.
- the over the upper support rollers 7,8 in the upper Work roll 4 initiated rolling force F is by in the two Roll stands 12, 13 built-in roll setting devices 21 generated that act on the upper backup roll chocks 11.
- the rolling force F acting on the upper pair of support rollers 7, 8 enables a factor of a factor due to the breakdown of forces into a horizontal rolling force component F h and a radial rolling force component F r when an equal coefficient of friction is applied between the upper support roller 7.8 and the upper work roller 4 1 / cos ⁇
- the operated by a pressure medium Work roll bending devices 17, 18 work between one lower, the contact between the support rollers 5,6; 7.8 and den Work rolls 3.4 ensuring and preventing slippage Contact pressure, which is also a permanent balancing of the Work rolls 3.4 guaranteed, and one as a positive Bending force acting maximum pressure.
- the regulation of the work roll bending devices 17, 18 takes place depending on the rolling force F, on the strip width 22 and the displacement position of the support rollers 5,6,7,8.
- the balancing devices 19, 20 for the backup rolls 5,6,7,8 have acting on the support roller chocks 10,11 Actuating cylinder with storage units for the ongoing change of Position of support rollers 5,6,7,8.
- the four support rollers 5,6,7,8 are to compensate for the occurring roll set deflection and to adapt to the Band width 22 of the strip material 2 by the same or different routes S independently of each other vertical center plane 23-23 of the rolling stand 1 in opposite directions axially displaceable.
