Definitions
- the invention relates to a device for adjusting the distance of the Abstreiforulißel from the scope of the chocks of a roll stand overlapping work rolls, wherein the scraper chisel is parallel to the rolling line in the direction of the nip and movable away therefrom.
- stand roller tables In hot rolling reversing stands usually stand roller tables are used, which ensure a transfer of the rolling stock from the work roll to the downstream roller table or from the upstream roller table on the work roll.
- the transition of the rolling stock from the work roll to the stand roller tables is usually via a scraper chisel, which is fixed between the work roll chocks or integrated in the roll stand table.
- the adjustment of the position of the chisel to the different roll diameters is made by different shims, so that it is possible to set a constant gap between the work roll and the chisel.
- the chisels remain in a fixed position to the work roll during operation and move up or down with the lower set of work rolls when adjustment of the pass line, e.g. B. by a hydraulic employment down in the framework takes place.
- This has the consequence that the position of the chisel changed to the stator roller table, since the stator roller tables are mounted in a fixed position in the stand. Due to the changing distances between the chisel and stand roller table, there may be problems in the transfer of the rolling stock, which is unacceptable especially if special requirements are made in this regard, such as. B. in aluminum rolling stands.
- the chisels With integration of the scraper chisel into the upright roller table, the chisels can be freely designed in terms of their resistance moment, so that they are able to absorb high loads resulting from the rolling process.
- the object of the invention is therefore to integrate the scraper chisel in the upright roller table while adjusting the position of the chisel to different operating positions and diameter of the work rolls, so as to keep the gap between the chisel and roller always constant.
- the scraper chisel is arranged on a horizontally displaceable stand roller table, wherein the movement of the stator roller table is linked to the vertical movement of the lower work roll, so that the scraper chisel is movable away from the work roll, when the lower work roll after moved up and vice versa.
- rolling stands are equipped with a hydraulic adjustment at the bottom of the scaffold, which allows the upper edge of the lower work roll to be raised or lowered to different levels.
- the hydraulic adjustment also allows control of the rolling stock thickness, ie the thickness of the rolling stock can be set constant over the entire length of rolling stock within certain tolerances.
- the thickness control takes place permanently during the rolling operation, so that the position of the lower work roll is inferior to a constant change. This position change of the lower work roll must be taken into account when setting the gap to the chisel.
- the invention will be explained below using an exemplary embodiment.
- Fig. 1 is a partial schematic representation of a rolling stand with different jobs of the lower working and support roller
- the rolling stand is only partially shown and designated 1.
- the support roller 4 and the work roll 5 are mounted in chocks 2 and 3.
- the horizontal adjustment or displacement of the stator roller tables is carried out by the adjustment. 9
- the entire stand roller table can be constructed, for example, from two essential components, one mounted on the roll stand pivot frame 10 and a stand roll table consisting of a base frame 7, on which the individual stator rollers 8 and the Abstreiforulißel 6 are mounted.
- a support frame is attached to the roll stand, in which the stand roll table is arranged displaceably.
- the support frame may be one or more parts.
- stator roller table is arranged horizontally displaceable in the pivot frame, wherein - in both versions - the displacement can be measured via position sensor.
- the position sensors allow an accurate determination of the current position of the stator roller table, so that it is possible to incorporate this in a position control.
- This position control is linked to the position control of other components in the Scaffolding, so that it can be ensured that the stand roller table is always in an optimal position to the work rolls. This means that when the lower work roll moves up and vice versa, the stand roll table and thus the scraper chisel moves outward (away from the work roll). To change the work rolls, the stand roll table is moved to the outermost position to ensure that there is no collision between the chisels and the work roll chocks when extending the work roll sets.
- the invention can be used in all rolling mills, which are equipped with a stand roller table and are placed on the special requirements in terms of the transfer of the rolling stock from the work roll on the stator roller table.
- the horizontal displacement of the stator roller table can be achieved for example by a hydraulic adjusting device.
- Other drives such.
- electrically operated threaded spindles are also possible.
- the horizontal movement or displacement of the stand roller table is associated with the vertical movement of the lower work roll.
- Linked in this case means that both an electrical and a mechanical coupling of the two types of movement is structurally possible.
