Definitions

  • the invention relates to a method for producing shaped steel, in a shaped steel rolling mill with a double reversing roughing stand and in a tandem stand group, combined universal working stand, flanged edging stand and a universal finishing stand provided on the output side.
  • the invention also relates to a shaped steel rolling mill for carrying out the method.
  • Such a method, corresponding to the genus, for producing shaped steel is known from the prior publication JP-A 56 109101.
  • the aforementioned prior publication describes a girder mill consisting of a reversing roughing stand and an adjoining tandem stand group consisting of a universal reversing roughing stand and an associated flange-upsetting stand as well as a separate universal finishing stand.
  • the prefabricated stand which is separate from conventional girder mills, has been moved to the universal work scaffold group.
  • the universal finishing stand is open during the reversing roughing pass and is not in rolling contact with the form steel.
  • the universal finishing stand is set to the finished size only for the last pass of the section steel, so that - the finish stitch is rolled in the universal finishing stand.
  • the form steel is formed in a tandem stand group consisting of a universal work stand, a flange compression stand and a universal finishing stand. Only the universal working scaffold and the flanged compression stand are reversing working scaffolds.
  • the universal finishing stand is open during the forming process.
  • the form steel is passed through the opened roll gap of the finishing stand.
  • the roll gap of the universal finishing stand is not moved until the last stitch, the finish stitch, and the shaped steel is subjected to a single final stitch in the entrance.
  • the shaped steel is preformed with X-stitches in the universal working scaffold and in the flange compression scaffold; the flanges are only directed into the H-shape in the final stitch.
  • the pre-rolling of the shaped steel with X-stitches is disadvantageous for the microstructure formation in the transition from the web to the flange.
  • a triple tandem stand group which consists of two universal work stands and a flanged compression stand, the compression stand being arranged between the universal stands and this triple tandem group works in reverse operation.
  • the shaped steel is pre-rolled in this tandem stand group.
  • the shaped steel is then finish-rolled in a non-reversing universal finishing stand, which is at a greater distance from the roughing stand group mentioned.
  • the section steel is subjected to either only X-stitches or only H-stitches, which is disadvantageous for the structure formation in the transition from the web to the flange.
  • a disadvantage of this known rolling mill is the large length and the fact that the finishing stand is only used for a single pass, the finishing pass, while it is idle in the stand-by in the rolling line during reversing operation of the roughing stand group.
  • the invention is based on the object of providing a method for producing shaped steel of the type mentioned at the outset, by means of which both the space requirement and the required outlay are kept low and the forming capacity is nevertheless increased by better utilization of all the rolling stands arranged in the rolling mill.
  • the tandem scaffolding group works simultaneously as a reversing tandem scaffolding group in a reversing, reducing manner and the universal finishing stand is included in the production of the shaped steel in a reversing manner in all reduction stitches, and also the last finishing stitch in this Universal finishing stand is carried out and the universal finishing stand is set for a smaller reduction than the universal working stand during the reversing reduction of the shaped steel.
  • the universal finishing stand included in the reversing tandem stand group replaces the reversing working universal working stand, which is usually arranged in a three-way tandem group, and becomes a reversing working universal finishing stand .
  • a conventional steel mill is shown schematically.
  • blocks heated in a pusher furnace are pre-rolled in a reversing roughing stand 1, which is designed as a two-roll stand, in a number of passes, usually between seven and fifteen passes.
  • the preform is passed on to a reversing tandem scaffold group 2, which consists of a universal work scaffold 4, a flange compression scaffold 5 and a universal work scaffold 6.
  • the desired profile is largely approximated by repeated rolling in three or five passes.
  • the rolling stock enters a finished stand group 3, in which the support flanges are brought to the exact desired width again by means of a flange-upsetting stand 7, while the universal finishing stand 8, the final shape of the profile and determines the surface quality of the rolling stock.
  • An infeed roller table 9 leads to the reversing roughing stand 1, a feed roller table 10 is provided between it and the reversing tandem stand group 2, the reversing tandem stand group 2 is followed by a transfer roller table 11, and the finishing stand group 3 is an outfeed roller table 12 downstream, which leads, for example, to a cooling bed.
  • Both the reversing roughing stand 1 and the reversing tandem stand group 2 are heavily used for the forming by reversing and thus optimally used. Only the flanging mill 7 and the universal finishing stand 8 are used only for a very small reduction and are more used to secure the desired narrow tolerances of the profile obtained and the surface quality of the rolling stock.
  • the arrangement according to FIG. 2 is used for better utilization of all scaffolding.
  • the roughing from block to rough profile is effected by a reversing roughing stand 1, which allows a high forming capacity due to a large number of passes, for example five to thirteen passes.
  • the following reversing tandem scaffolding group has a universal working scaffold 4, a flange upsetting scaffold 5 and a universal finishing scaffold 8. These three scaffolds are also largely used by reversing at least twice, possibly more often, so that three upsetting stitches and six universal stitches can be achieved with just two reversals. However, the use of this reversing tandem scaffolding group 16 is not pushed up as much as that of the reversing tandem scaffolding group 2.
  • FIG. 3 A practical embodiment of the compact, high-performance shaped steel rolling mill is shown schematically in FIG. 3.
  • the block-heating pusher furnace 17 with its loading devices is shown as well as a descaler 18 after it.
  • the heated and descaled blocks are fed via an infeed roller table 9 to the reversing roughing stand 1, to which a roller quick-change device 19 is assigned and edging and shifting devices 20 in front and are subordinate.
  • the preliminary profiles are fed to the reversing tandem stand group 16 via a feed roller table 10 which is equipped with a cropping saw 21.
  • the scaffolding 4, 5 and 8 of this group is assigned a scaffolding changing device 22 which allows the scaffolding to be exchanged for refurbished scaffolding, it being possible to install scaffolding intended for duo or universal operation.
  • a downstream run-out roller table 12 leads to a cooling bed 24 via a tub shear 23, which can be used, for example, for dividing billets.
  • the vertical rolls of the universal work stands are slightly double-conical in such a way that their bales taper from their central planes to their roll neck.
  • the profiles rolled here have flange halves slightly bent outwards, so that one speaks of "X" pre-profiles, and only the universal finishing stand contains essentially cylindrical roller balls, so that the flange halves receive a common outer plane and the desired “H “Profile.
