Definitions

  • the invention relates to a method for rolling shaped steel, in particular sheet piles, by successively rolling in successive calibers, at least two of which are combined in a common duo stand, and a reversing line for carrying out the method.
  • shaped steel such as sheet piles is rolled in successive calibers by caliber rolls. Of these calibres, two, at most three, can be provided in a roll set.
  • the width of the calibers already makes considerable roll lengths necessary, so that relatively large roll diameters are also required to achieve sufficient stability. Since at least ten, but usually larger numbers of calibres are generally required for roughing and finishing rolling, at least five reversible duo stands, which have the long and a large diameter, are required for a conventional reversing line for rolling sheet piles having roller sets are also relatively large because of this and are therefore expensive to design.
  • the invention is based on the object of reducing the outlay on scaffolding and associated roller tables, tractors and the like which is to be carried out for the generic rolling method and a reversing line suitable for carrying out the method.
  • the first of the usual closed calibers with the stands comprising them are replaced by preferably a universal stand, in which several in succession in the reversing process with further adjustment of both the horizontal and vertical rolls Stitches or a number of stitches are rolled.
  • a universal stand in which several in succession in the reversing process with further adjustment of both the horizontal and vertical rolls Stitches or a number of stitches are rolled.
  • a reversing line has proven itself, in which at least one universal stand and at least one compression stand assigned to the universal stand or stands are arranged in front of the remaining dual-mill stands with caliber. It has proven to be essential here to equip the universal stand and the upsetting stand with profiled rollers.
  • the vertical rollers are expediently equipped with an upper cylindrical region, from which the rollers reinforce downward, for example in a parabolic manner, while the horizontal rollers are profiled in the shape of an inverted W with emphasized outer leg ends.
  • the rollers of the edger are also advantageously profiled and have effective outer surfaces, in particular in the width regions of the bale ends of the horizontal rollers.
  • a reversing line is shown schematically, which in the rolling direction one after the other a universal stand 1, an upsetting stand 2 and, indicated by the division of the rolls by cross lines, two in the exemplary embodiment Contains three closed caliber duo mill stands 3 and 4 each.
  • the universal scaffold 1 in conjunction with the upsetting scaffold 2 replaces several heavy duo roughing stands that would otherwise be required at this point.
  • the top roller 5 profiled in the manner of an inverted W works into the slab 6.
  • the roll thickening 7 located in the central area of the bale will not yet touch the slab 6 at the first stitch, but at the end of the bale there are stressed roll bundles 8 corresponding to the free legs of the "W" in the slab.
  • the lower roller 9 is effective with two symmetrically arranged bundles 10, and the flanks are formed by the vertical rollers 11, which have a cylindrical bale in the upper region which widens parabolically downward to form a bundle 12.
  • the slab 6 is guided several times through the universal stand, with the rolls being set further against each other until the desired profile shape of the rolling stock is achieved with little stand, roll, roller table and cross tractor effort.
  • the slab 6 can here spread outward and outward in an uncontrolled manner. It is therefore expedient to carry out an upsetting stitch after one of the stitches of the universal stand, in which, owing to the shape of the upsetting rolls shown in broken-away half-section in FIG 5 and 11 of the universal stand 1 correspond, and which are therefore not accessible by its rolling.
  • An improved and defined design of the "fingers" in the lock areas of sheet piles is hereby achieved.
  • This closed caliber formed between work rolls 13 and 14 of the duo roll stand 3 can have, for example, the shape indicated in FIG. 4, which shows a broken-off half section of a length range of a roll set having a caliber.
  • the desired final profile is finally achieved by further rolling in closed calibres of the duo mill stands 3 and 4.
  • the invention is not limited to the arrangement of a single universal scaffold; there is also the possibility of replacing other of the previously usual caliber frames with another universal frame. It is only essential that the finish rolling takes place in the usual manner, for example in closed calibres, within narrow tolerances and thus a finished product kept in tight tolerances is obtained regardless of the wide adjustment range used for the pre-rolling.
  • the first runs of a slab 6 to be rolled into sheet piles are shown schematically on the basis of the sequence of FIGS. 5 to 10. 5, in particular the roller bundles 8 and 10 of the horizontal rollers 5 and 9 become effective in the first pass of a universal stand, and in the course of the further deformations by the passages No. 3 and No. 4 shown in FIGS. 6 and 7, the final profile, even if with an excessive thickness, already approximated.
  • the rolling stock 18 passes through the horizontal rollers 13 and 15 of an upsetting stand.
  • Roll bundles 14 roll a joint of the lock area of the sheet piles, which was already formed in the previous passes, and the areas adjoining the outside delimit the edge seams of the rolling stock formed in the previous passes, the so-called "fingers".
  • the roll stands cannot be built one behind the other in relatively short distances, as is forced in FIG. 1, since the roll stands are each assigned sufficiently long run-out roller tables. Often you will not assign long connecting roller tables to the stands, but arrange them, at least in part, parallel to each other, so that the length of the halls accommodating the rolling mill is saved, but tractors are required to move the rolling stock from one to the next, arranged in parallel Bring roller table. In addition to the saving of the scaffolding according to the invention, this also results in a corresponding saving in the built-up base area and in the associated roller tables and tractors.
