Definitions
- the invention relates to a Reversiergerüst, in particular Steckel Reversiergerüst, the at least one upper and one lower support roller and a respective associated upper and lower work roll with scaffolding inlet side and scaffold outlet side associated upper guides.
- Roll bars are also installed in the lower work roll chocks. However, these are not in contact with lower guides, both top and bottom in such a reversing stand no contact between roll bar and work rolls. This is also not necessary since, owing to the rather large initial strip thickness of about 40 mm, there is no danger of rolling stock entering the gap between the work rolls and the rolling beam.
- the pre-wall thicknesses are then rolled from approx. 40 mm to an end strip thickness of up to approx. 1 mm. This is done either in a multi-stand finishing line in tandem arrangement or in one or two scaffolds in Steckel type.
- the opening band in the Reversing operation rolled out in several passes to finished product with an end strip thickness of up to approx. 1 mm.
- finished scaffolds usually arranged on the upper inlet and outlet guides upper scraper and the work rolls also associated lower scrapers, which are also provided both scaffold inlet side and scaffold outlet side, a permanent contact with the respectively associated upper or lower work roll.
- the invention has for its object to provide a solution that makes it possible to use a Reversiergerüst both as Vorgerüst as well as ready scaffold.
- the invention provides a reversing device which fulfills both the requirements for a "roughing stand lift" and for a "finishing stand operation".
- the reversing stand according to the invention it is possible to use both press the upper and lower scrapers to the respective associated work roll as well as to pivot away the upper and lower guides for roll change can.
- Steckel reversing stands can be equipped in such a way that they can roll out slabs with a thickness of approx. 250 mm in reversing operation to a finished product with a final strip thickness of approx. 1 mm during pre- and finishing stand operation.
- the upper guide is connected to an actuator via a coupling with the upper Stauerwalzenausbalanci für assupra and thus guided displaceably from the lower vertical guide and pulled out. This allows a simple mechanism push out the upper guides from the work area of the work rolls and thus release the upper work roll chocks.
- Clamps, ball heads and universal joints or simply movable screw connections are preferably used as couplings.
- a further embodiment of the invention provides that an arranged third actuator for adjusting the upper guide connects to the frame or is attached to the Stauerwalzenausbalanci für assupra.
- This optimal mounting of the upper guides is selected depending on the available space, which is easily accessible and easy to assemble and disassemble especially in the course of possible maintenance or repair work.
- a further embodiment of the invention provides that an upper scraper is arranged opposite to the upper work roll, and this scraper is adjustable or can be pressed against the work roll via a second actuator.
- the arranged second actuator ensures that the scraper always has uniform contact with the upper work roll over its entire length. The wear on the scraper tips is then preferably compensated by the continuous pressing of the scraper against the work roll of the second actuator.
- a further embodiment of the invention provides that a lower scraper with a fourth actuator is arranged so that the scraper is pressed by the actuator against the work roll or moved away from the work roll and thus can be swung out of the input or removal area of the work rolls , Thus, the space for the work rolls is freely accessible without major assembly work on the arranged scrapers are necessary. Both scrapers are now out of the outer contours of the work roll chocks and release them for work roll change.
- the arrangement of the scrapers can be provided in a particular embodiment of the invention so that the pivoting away of the scraper up or / and down is effected. This allows a flexible adaptation to the available space.
- the embodiment of the invention described above is favored by the fact that the upper and lower scrapers are mounted gimbal. With this type of storage a swing away in any direction is possible.
- the upper and lower scrapers can be swiveled out of the working area of the work roll chocks.
- the actuators are designed as a lifting cylinder in the form of a hydraulic cylinder or pneumatic cylinder, or in the form of a driven spindle. This makes it possible, according to the existing on-site connections, such as hydraulic connections, pneumatic connections or electrical connections, or a combination of all three according to the structural conditions, to choose an optimal actuator, which the space of the Work rolls affected as little as possible and ensures an optimal adjustment.
- the upper guide on the reversing stand is rotatably arranged on connecting elements, on each of which one end of a lifting cylinder with clamping head and one end of a second pneumatic cylinder engages.
- connecting elements on each of which one end of a lifting cylinder with clamping head and one end of a second pneumatic cylinder engages.
- FIG. 1 is a schematic sectional view of a section through a partial area of a Steckel reversing stand, wherein the left partial representation of the rolling operation and the right partial representation represents a work roll change position,
- FIG. 2 is a schematic representation of a partial view of a Steckel Reversiergerüstes in the rolling direction and in
- Fig. 3 in schematic plan views in the left part of the image on an upper guide and in the right part of a lower guide in each case in their rolling operation position.
- both the upper work roll 1 and the upper backup roll 2 and the lower work roll 3 and the lower backup roll 4 have contact with each other.
- the upper scrapers 11 are located on the associated upper work roll 1 and the lower scrapers 13 on the associated Neten lower work roll 3 at.
- Held the upper scraper 11 each in an upper guide 8, which is connected via a first actuator 6, for example a lifting cylinder with clamping head with an upper Stützwalzenausbalancitation 5.
- the upper guide 8 is guided in lower vertical guides 9 and upper vertical guides 10 in the total designated 20 Steckel Reversiergerüst.
- the upper scrapers 11 are rotatable, integrated in particular by means of cardan suspension in the upper guide 8 and hinged thereto relative to this pivotally.
- a second actuator 12 for example a pneumatic cylinder, which is arranged on the upper guide 8, the respective upper scraper 11 can be pressed against the upper work roll 1.
- the axis of rotation 16, about which the upper scraper 11 is pivotable, is arranged and positioned such that the tip of the upper scraper 11 over the entire length of the scraper 11 in contact with the upper work roll 1 can be brought.
- the on this longitudinal edge of the upper scraper 11 adjusting wear is compensated by the continuous adjustment by means of the second actuator 12.
- zenausbalancitation 5 and the upper guide 8 forms. All necessary or resulting changes in the height of the nip 15 are moved in the rolling operation by means of the locked upper guides 8 on the upper Stauerwalzenausbalanci réelle 5.
- the strokes of the first actuators 6 are adjusted in position-controlled manner in accordance with the current work roll and back-up roll diameters and locked by means of the clamping head integrated with the lifting cylinder 6.
- the lower scrapers 13 are likewise pivotable about axes or pivot points 17, preferably cardanically, in the region of the associated lower work roll 3 on the reversing stand 20.
- a fourth actuator 14 not shown, which is preferably a Walzbai- ken upstream lower scraper 13 is pressed to adapt the upper scraper 11 in an analogous manner to the lower work roll 3.
- each lower scraper 13, two fourth actuators 14 are assigned, which are arranged symmetrically to the lower scraper 13 and on the one hand on the lower scraper 13 and on the other hand supported on reversing 20 or arranged thereon elements.
- two symmetrically arranged lifting cylinders 6 are associated with each upper guide 8 and on both sides of each upper guide 8, these are each assigned a lower vertical guide 9 and an upper vertical guide 10 which cooperate with corresponding counter-elements arranged on the reversing stand 20.
- the respective upper guide 8 On a connecting element 19 which is fastened to the lifting cylinder 6, the respective upper guide 8 is pivotable about an axis 21 with a third actuator 7, likewise pivotably mounted on the connecting element 19 about an axis 22, the other end of the actuator 7 is pivotally mounted about an axis 23 at a distance from the connecting part 19 portion of the respective upper guide 8.
- Each upper guide 8 is thus associated with a number of third actuators 7 analogously to the number of first actuators 6. In the exemplary embodiment, these are two hydraulic cylinders.
- both the upper scrapers 11 and the lower scrapers 13 are so far outside the outer contours of the work roll chocks or work roll chocks that they are now released for the work roll change and exposed.
