Definitions
- the invention relates to a roll stand for the stepped rolling of a metal strip, in particular of steel, aluminum, copper or a copper alloy.
- the invention further relates to a rolling train with at least one such rolling stand and a corresponding method.
- Roll stands and methods for producing step-shaped thickness profiles across the width of a strip-shaped metal strip are known in the art, e.g. from German patent application DE 198 31 882 A1 or German Patent DE 101 13 610 C2 basically known.
- desired thickness profile e.g. Stair profiles recommend the two documents to longitudinally roll the metal strip, which originally typically has a rectangular cross-section, with a plurality of pressure rolls offset in the rolling direction.
- the offset in the transport direction of the metal strip or juxtaposed pressing rollers each press into the supported by a support means metal strip and deform it in this way as desired in the width direction.
- the pressure rollers proposed for use in said publications allow only a locally very limited processing of the metal strip in a narrow range in the width direction; It is therefore, as I said, a plurality of such pressure rollers in a staggered arrangement required lent to e.g. to roll wider steps into the metal band. Due to the large number of required pressure rollers and their staggered arrangement, the structure of such known rolling stands for realizing step profiles in metal bands is quite expensive.
- This object is solved by the subject matter of patent claim 1.
- the material rolled off from the height of the metal strip or the material flow resulting therefrom is evenly distributed in the longitudinal direction of the metal strip, advantageously without corrugation.
- the inventively used for this mill stand is structurally simple and space-saving, because it has only transversely to the direction of the metal strip juxtaposed part rollers, but not a plurality of staggered in the direction of running part rollers.
- sub-rollers are arranged "at the same height" next to each other, means that the side rollers arranged side by side on one side the metal strip are not offset in the transport direction of the metal strip to each other.
- the invention relates only to the reduction in thickness of pre-profiled step profiles, wherein the advantageous effect that the resulting metal strip is wave-free, occurs only when the Dickenreduk- tions for the individual stages transversely to the transport direction of the metal strip under consideration of the claimed law individually calculated and performed become.
- the setting of the sizes of the partial rolling gaps is carried out automatically with the aid of a setting device with knowledge of the step heights of the incoming step-shaped pre-profiled metal strip.
- a setting device with knowledge of the step heights of the incoming step-shaped pre-profiled metal strip.
- the rolling stand is designed for hot rolling or cold rolling of the metal strip.
- the above object of the invention is further achieved by a rolling train, in particular a tandem system.
- This rolling train then comprises a first roll stand with profile or caliber rolls for the step-shaped pre-profiling of the metal strip.
- at least one second rolling stand is then connected downstream of the first rolling stand or roughing stand, this second rolling stand being designed according to the invention.
- the at least one downstream roll stand then takes place a reduction in thickness of the stepped metal strip, wherein the heights of the individual adjacent stages are individually reduced according to the claimed law.
- the second rolling mill can be followed by further rolling mills according to the invention.
- the inventively designed upstream rolling mills then take over the necessary provision of a step-shaped pre-profiling of the metal strip for each downstream rolling stands according to the invention.
- a plurality of roll stands according to the invention arranged one behind the other is required, in particular, if the thickness of the metal strip is to be greatly reduced.
- a strong reduction in thickness can also be realized by a single reversing stand, which is designed according to the invention.
- the invention is a total of 6 figures attached, wherein
- Figure 1 shows a first embodiment of the rolling stand according to the invention
- Figure 2 shows a cross section for the first embodiment of the rolling stand according to the invention according to Figure 1;
- 3a shows a cross section of the metal strip after leaving the rolling mill according to the invention according to the first embodiment;
- Figure 3b shows an alternative cross section of the metal strip after leaving the mill stand
- Figure 4 shows a second embodiment of the rolling mill according to the invention
- FIG. 5 shows a cross section of the rolling mill according to the invention according to the second embodiment.
- FIG. 6 shows a cross section through the metal strip after leaving the rolling mill according to the invention according to the second exemplary embodiment
- FIG. 1 shows a first exemplary embodiment of the rolling mill 100 according to the invention.
- the sub-rollers are open the same height arranged side by side, ie they are not offset in the transport direction of the metal strip.
- the two outer sub-rollers 110-1, 110-3 are mounted in FIG. 1 by way of example on a common axis A and, if appropriate, are therefore also respectively set in the same manner and to the same extent relative to the support device 120.
- the employment of the individual sub-rollers 110-i with respect to the support device 120 is advantageously carried out automatically with the aid of a Anstell Road 130, but always in compliance with the claimed law:
- ⁇ hj the reduction in thickness of the metal strip through the rolling mill according to the invention in the region of the first part roll or step;
- hj the size of the i'th partial nip or the thickness of the expiring from the rolling mill according to the invention metal strip in the region of i'ten stage.
- FIG. 2 shows a side view of the first exemplary embodiment shown in FIG. 1 for the mill stand 100 according to the invention.
- the middle part roller 110-2 is not supported on the axle 112-5. Instead, as shown in FIG. 2, it is rotatably mounted in a separate roller cage 112.
- the adjusting device 130 it can also be adjusted individually relative to the supporting device 120 independently of the two outer partial rollers 110-1 and 110-3.
- the direction of transport of the metal strip is indicated by an arrow pointing to the right and, moreover, the resulting reduction in thickness, in particular in the region of the middle sub-roller 110-2, is clearly recognizable.
- FIG. 4 shows a second exemplary embodiment of the rolling stand 100 according to the invention. It differs from the first exemplary embodiment only in that the support device 120 is no longer in the form of a uniform cylinder but is mirror-inverted to the part rolls on the opposite side of the metal strip.
- the sub-rollers 120-1, 120-2 and 120-3 each have the same bale length as the mirror-opposing sub-rollers 110-1, 110-2 and 110-3.
- the two outer sub-rollers 120-1 and 120-3 are employed via a common axis 120-5 opposite the metal belt 200 and opposite the opposed metal rollers, respectively.
- the from the opposite arrangement of the sub-rollers 110-1, 120-1; 110-2, 120-2; 110-3, 120-3 resulting Detailwalzspalte have heights of hi, h 2 and h 3 .
- FIG. 5 shows the mounting of the two middle sub-rollers 110-2 and 120-2, each in suitable roller cages 112.
- FIG. 6 shows a cross-sectional view of the metal strip 200 emerging from the rolling stand according to the second exemplary embodiment.
- the originally typically rectangular-shaped, non-profiled metal strip is first pre-profiled stepwise in a roughing stand.
- This pre-profiling takes place in geo-
- the steps in the metal strip 200 are formed with a step width which corresponds at least approximately to the bale length of the individual part rolls 110-1, 110-2 and 110-3 of the downstream rolling stand.
- the step-shaped pre-profiled metal strip then enters into the rolling mill 100 according to the invention and is reduced in thickness in the region of each individual sub-roller 110-i in accordance with equation (1).
- the reduction in thickness in consideration of the equation (1) offers the advantage that the metal strip, after leaving the rolling stand according to the invention, does not have any waves in the longitudinal direction.
- the desired thickness hi of the metal strip 200 for the area of a sub-roll 110-i or a step after passing through the rolling stand according to the invention is fixed.
- the knowledge of ⁇ h-i and hi enables the calculation of the quantity ⁇ according to the formula (1) to:
- Direction of transport of the metal strip is to perform this just performed exemplary calculation of the relative roll gap sizes for each pair of adjacent Operawalzspalten separately.
- the invention finds a particularly advantageous use with thin metal bands having an original thickness of less than 10mm.
- the method according to the invention can be used both during hot rolling and during cold rolling of metal strips.
- the application of this method according to the invention is particularly advantageous during hot rolling, because then a wave-free step profiling of the metal strip can be realized already in a very early production stage.
- a field of application is e.g. the production of motor base frames for the automotive industry.
- cold rolling strip geometries can be realized, which can replace the flexible strip rolling in the presently known form with low production costs.
- An exemplary area of application here too is the automobile industry, especially the production of underbody panels for automobiles.
