Definitions

  • the invention relates to a method and an apparatus for rolling of beams from pre-profiles on a rolling mill consisting of a Roughing stand and a compact group of two arranged behind it Universal rolling stands with flanged compression stands arranged in between, whereby the outlet-side universal roll stand as a finishing stand is trained.
  • a generic rolling mill is from European patent 02 65 757 known. This known rolling mill is used to roll finished profiles from pre-profiles that come from a continuous caster. In the Description of this prior art is pointed out that the Dimensions of the pre-profiles leaving the continuous casting device by the Mold dimensions are largely determined, so that the rolling mill to Rolling out these pre-profiles to be matched to this continuous casting profile got to.
  • the known solution was looking for a way out of this Continuous casting profile on one and the same rolling mill with finished profiles significantly larger final dimension differences than before and suggests those pre-profiles that are not directly in the Compact rolling group can be rolled out in the front of the Compact roll group arranged, designed as a compression mill reducing pre-deforming.
  • the object of the present invention is to provide a method for rolling Propose beams from pre-profiles, the waiver of the heavy breakdown scaffolding an economical manufacture of beams enables without the flexibility and variety of dimensions of the restrict rolling beams.
  • a corresponding adjustment of the Roll stands are another object of the invention.
  • the invention proposes that for at least one breakdown stitch that is designed as a vertical scaffold Roughing stand, the first universal stand and the flange compression stand as Breakdown group are used, the following the Breakdown stitches one or more pre-stitches on the first Universal scaffold and the flange compression scaffold are performed before at least one finish stitch on the universal scaffold on the outlet side is performed.
  • the Lifting up from the roughing stand, but also an additional one Reduction of the web can be made.
  • the first Universal roll stand made an empty run of the Upset rolling of the flange upset in the web area enables.
  • one is placed on the three scaffolds arranged one behind the other optimal breakdown rolling made by the adjustability the scaffolding great flexibility when using the pre-profiles, as well as the variety of rollable finished profiles.
  • the present invention used in departure from the teaching of the prior art Technology always in context and simultaneously with the first universal scaffold and the flange compression scaffold of Compact rolling group, whereby only those aimed at by the invention Results are achieved.
  • the roughing is done after the universal breakdown rolling exclusively on the first universal and flange compression stand the compact rolling group, d. H. without using the pre and Universal finishing stand in one or more stitches; the finishing stand is used exclusively for finish rolling.
  • a variant of the invention which is also more flexible This enables the road and significantly increases production characterized in that the roughing stand as reversible Universal breakdown scaffolding group, consisting of a universal scaffolding is formed with an immediately subsequent vertical compression frame and used to perform multiple breakdown stitches several preliminary stitches using the first universal scaffolding and of the flange upsetting stand and at least one finish stitch on the Connect the universal scaffold on the outlet side.
  • the roughing stand as reversible Universal breakdown scaffolding group, consisting of a universal scaffolding is formed with an immediately subsequent vertical compression frame and used to perform multiple breakdown stitches several preliminary stitches using the first universal scaffolding and of the flange upsetting stand and at least one finish stitch on the Connect the universal scaffold on the outlet side.
  • a rolling mill known from EP-A 0265 757 for rolling beams Pre-profiles, in particular continuous casting profiles with a roughing stand and one behind it arranged compact group consisting of two universal scaffolds with in between arranged flange-compression frame, in which the outlet-side universal frame is designed as a finishing stand, is further developed according to the invention in that the Roughing stand as a reversible universal breakdown scaffolding group, consisting of one Universal scaffold with immediately following compression frame and is designed as Universal scaffolding of the universal breakdown scaffolding group with a combination scaffold optional universal roller set and duo roller set can be used.
  • the universal breakdown scaffolding group can also be used as a roughing stand Profilstrasse can be used if desired.
  • the Horizontal rolls of the universal roll set, and the vertical rolls of the Compression frame of the universal breakdown scaffolding group at upright have rolled rolls standing upright rolled bales.
  • This itself atypical training of the universal roll stand makes this cheaper, because the elaborate profile grinding of the horizontal rollers is not necessary.
  • the smooth ones Rolls upset the flanges of the upright beams while the Flange edges with the vertically arranged upsetting rollers of the Edging stand are processed, which are also smooth rolled bales exhibit.
  • the vertical rollers in the universal stand reduce the web and keep the chamber size at the same time.
  • the universal breakdown scaffolding group makes one Rolling mill with high flexibility and lower investment volume created because the universal breakdown scaffolding group is cheaper is to create as a heavy breakdown framework with the extreme expensive caliber rolls. Compared to the latter, there is also the significant advantage of great flexibility and variability, both when Carrier rolls, even if the mill operator intends to To produce profiles on his rolling mill.
  • the roughing stand provided with vertical rollers is one Rolling mill according to the invention referred to rolling beams.
  • the compact rolling group is directly adjacent to the roughing stand VE, consisting of the first universal scaffold U1, the one designated HE Flange compression stand with horizontal compression rollers and the Universal finishing stand UF.
  • the inventive method for example two breakdown stitches in the VE roughing stand, Universal rolling stand U1 and flange compression stand HE driven, as in Figure 1 is represented by the crosses in the usual way.
  • the Universal finishing stand UF is for free passage of the rolling stock open.
  • the rolling stock passes through in reverse operation three preliminary stitches in the first universal scaffold U1 and flange compression scaffold HE before the universal finishing stand UF - moved to the final stitch - is used.
  • FIG 2 is roughly schematically indicated how the Breakdown sequence expires.
  • the upper illustration is based on the Dashed lines can be seen schematically, as by the action of Vertical rolling on the preliminary profile according to the direction of the arrow; a Reduction of the chamber dimension 2 as well as a thickening of the web 3 takes place.
  • the illustration below is schematic the first universal scaffold U1 shown, the preliminary profile 1 immediately goes through on it.
  • the horizontal universal roller 4 Web 3 reduced back to its original size or below while at the same time the flanges are further compressed.
  • the sequence according to the invention applies to all breakdown stitches the preliminary profile optimally compressed and guided in every respect, so that with great flexibility an adaptation of the previous profiles to the further rolling passes is made possible, and good dimensional accuracy of the Finished profiles can be expected, as was previously only possible using the Breakdown scaffolding was possible.
  • FIG Universal breakdown scaffolding group UBD is used. This exists from the universal scaffold U and the compression scaffold E, to which the Compact rolling group, consisting of the first universal stand U1, the Flange compression stand HE and the universal stand UF.
  • Figure 3 shows the sequence of the breakdown rolling in the usual representation, in which the preliminary profile is reversed in three passes through the Universal scaffold U and the compression scaffold E der Universal breakdown scaffolding group is guided.
  • the beam is pre-rolled after the universal breakdown rolling as in the illustration according to FIG. 1 in the first universal frame U1 and the flange upsetting stand HE in three passes with the Universal finishing stand UF, after that it will be The universal finishing stand is closed and the final stitch is carried out.
