Definitions

  • the invention relates to a rolling stand with a pair of Work rolls for rolling a metal strip, with Support rollers, of which the respectively assigned to them Work rolls are supported laterally and by means of a force generating device with an in direction the work roll directed support force acted upon are, and with backup or intermediate rolls, by one in the direction of its longitudinal axis in the roll stand slidable and removable from this chock are worn and each one of which you associated work roll in a substantially perpendicular to the direction of movement of the metal strip supports direction.
  • This task is accomplished by a rolling mill with the in the Claim 1 specified features solved.
  • the support rollers from the Range of movement of the support roller and possibly further Rolling chock to be moved out.
  • the support rollers regardless of the rollers of the chock to wait or to replace.
  • Another essential advantage of the invention is in that it is no longer necessary, the spatial Arrangement of the rolls carried by the chock the need for articulated storage of Adjust support rollers.
  • the resulting space opens the possibility for the interpretation of the support, Intermediate and work rolls a larger area of Diameter to choose. For example, opposite the prior art larger roll diameter be provided so that a larger Abschliff Scheme is available and the respective rollers one have a longer life.
  • the Intermediate rolls according to the load of them each associated work roll are bent so that the dimensional accuracy of the roll gap is further improved.
  • the force generating device By the force generating device from the support roller the rest moves into the operating position, the takes over Force generating device not only the application of the Supporting force, but also serves as Adjusting device, with which the support rollers on the Delivered to work rolls or driven back from them can be. This supports the most cost-effective production of the invention Rolling stand.
  • the required support forces can be at low Generate space and energy requirements by the fact that the Force generating device a hydraulic or is pneumatically actuated cylinder. By one each or a plurality of such cylinders on the support rollers act, can be used for supporting the Support roller required forces exactly and with short Dose reaction times. This makes it possible over the Actuation of the support rollers with precisely divided Support forces to the nip between the work rolls influence.
  • the support roller at least over certain sections of its longitudinal extent on the Support beam is supported.
  • force generating devices such as actuating cylinder or similar
  • the supporting force transmitting aggregates is used in the inventive use of a Support beam on the one hand compared to the state of Technology lower number of force generating devices sufficient to make the desired smooth transition from the burden on each institution to reach.
  • the use of the Supporting beam a targeted deflection of the working and / or support roller.
  • a first possibility of training a storage is that the storage by roller bearings is formed, which at regular intervals along the support roller are arranged.
  • the storage by at least one hydrostatic Be formed camp is formed. Regardless of how the storage is formed, it can be in single, along the subdivided segments arranged respective support roller be, then expediently the respective Be assigned to Kraftbeetzyerungs soliciten.
  • the support bar in the longitudinal direction of the support roller is divided into two detachably connected parts, wherein the first part carries the support roller and the second is coupled to the force generating device, can be carried by the respective support beam Replace support roller particularly easily and quickly. This especially applies when the first, the support roller carrying part in its longitudinal direction displaceable on the second part of the support beam is held.
  • the rolling stands W1, W2 each have two work rolls 1.2 on.
  • the work rolls 1,2 are in vertical Direction in each case via an intermediate roller 3,4 at one Supported roller, not shown, whose Rotary axis in the same plane as the axes of rotation of the Work rolls 1,2 and the intermediate rolls 3,4.
  • the Intermediate rollers 3,4 are in a chock 7 and the Not shown backup rolls in a likewise not stored own chock, while the Work rolls 1,2 loosely held in the rolling stand W1, W2 are.
  • Between the work rolls 1,2 is a roll gap W formed in which a in the conveying direction F rolled metal strip B is cold rolled.
  • the chock 7 is on a not shown Slidably mounted guideway and can in his Longitudinally parallel to the axes of rotation of the Working, intermediate and support rollers from the respective Rolling stand W1, W2 are pulled.
  • Each work roll 1, 2 are two support rolls 8, 9, 10, 11 assigned, one of each side of the work roll 1.2 is assigned.
  • the support rollers 8, 9, 10, 11 become each supported by a support bar 12,13,14,15.
  • the support beams 12,13,14,15 are each in two parts 12a, 12b divided, the division plane vertical is arranged and extends parallel to the plane, in which the axes of rotation of the work rolls 1,2, the Intermediate rollers 3,4 and the support rollers, not shown lie.
  • the second part 12b of the respective support beam 12,13,14,15 carries the this support beam 12,13,14,15 respectively associated support roller 8,9,10 or 11.
  • About one at the respective first part 12a trained guide rail 12c and retaining pin 16 is the respective second part 12b on the first part 12a in FIG slidably held in its longitudinal direction, so that it with the supported by him support roller 8,9,10 and 11, respectively the respective rolling stand W1, W2 can be pulled.
  • hydrostatic bearings 18 arranged.
  • the bearings 18 are at the respective Support beams 12,13,14,15 supported and are about a Supply line 19 in the second part 12b of the respective Support beam 12,13,14,15 supplied with pressurized fluid.
  • roller bearing 118th are for lateral support of the support rollers 8,9,10 and 11th along the support rollers 8,9,10 and 11 in regular Intervals on the support beams 12,13,14,15 roller bearing 118th arranged.
  • the roller bearings 118 are also on the respective support beams 12,13,14,15 supported.
  • Each support beam 12,13,14,15 are each several in regular intervals along the respective Support beam 12,13,14 and 15 placed hydraulically associated actuating cylinder 20,21,22,23, in the side of the chock 7 arranged columns 24th or 25 of the roll stand W1, W2 are attached.
  • the pistons 20a, 21a, 22a, 23a of the actuating cylinder 20,21,22,23 are with the first part 12a of the respective support beam 12,13,14 or 15 coupled.
  • the movement axis X of the pistons 20a, 21a, 22a, 23a are each in the direction of the nip W inclined arranged.
  • the support rollers 8,9,10,11 also together with the chock 7 from the rolling stand W1 or W2 are drawn. These are the support beams 12,13,14,15 into a position in which their respective guide rail 12c in alignment with each outer edge of the chock 7 are arranged. At the Pulling out the chock 7, the parts 12 a of Support beams 12,13,14,15 and with them the respective Support roller 8,9,10,11 together with the chock 7th pulled out of the rolling stand W1, W2. In this way forms the chock 7 an assembly and disassembly, the it allows on a special auxiliary device of this kind to renounce.
