Definitions

  • the invention relates to a combined, continuously working high-performance fine steel and wire mill, in the roughing mill and in the intermediate mill and / or in the finishing mill both CL stands with rolling rings supported on one side (overhung) and rolling stands with a module unit with double-sided (double) stored rolling rings are arranged.
  • the intermediate line or the finishing train of a wire and fine steel mill consisting of CL stands is not suitable for also rolling profiles, since this can generally lead to dimensional inaccuracies due to the flying bearing of the rollers. If you wanted to do this according to the current state of knowledge, separate conventional roll stands with double-sided roller bearings would have to be introduced into the rolling line. This is an expensive and complex solution since the rolling mill is primarily used for wire and round steel dimensions.
  • DE-B 2 025 640 shows a rolling mill with a plurality of roll stands, the individual roll stand being equipped with vertical and horizontal rolls which have roll rings mounted on one and two sides.
  • the rolling mill consists of six stands.
  • the first three roll stands are each equipped with a vertical and a horizontal pair of rolls, the vertical rolls of the first two roll stands being designed as guide rolls and the rolling stock resting against these rolls at least on sections of its outline, and the horizontal rolls of the first two roll stands being curved - Or V-shaped profiles are formed and are provided for the actual rolling of the rolling stock.
  • the vertical rolls of the third roll stand are for rounding off the corners of the rolling stock and the horizontal rolls of the third roll stand are for the final profiling of the rolling stock to the final dimension or the final cross section provided.
  • the arrangement of horizontal, overhung roller rings and of vertical, double-sided roller rings is used to produce electrical sector cables, the rollers of a pair of rollers having differently shaped profiles that are wider than the greatest width of the rolling stock in the direction of the roller axis. With such a rolling mill, it is not intended to roll profiles with high tapping cross sections and high forming resistances.
  • AT-B 256 006 describes a rolling mill for wire or for profiled rolling stock.
  • the core of the rolling mill is a roll stand with horizontal rolls mounted on both sides in stands, which are preceded by two stands that hold contact rolls and which is followed by an auxiliary stand.
  • the auxiliary stand has vertical rollers.
  • the auxiliary stand can serve a wide variety of purposes, for example as a pull-out driver, in order to pull the rolling stock that is running out of the rollers under tension.
  • the auxiliary stand can be used for leveling the rolled profile, for which purpose it is then arranged with rolls offset by 90 ° to the rolls of the roll stand.
  • the auxiliary scaffold should also make it possible to produce undercut profiles, for example profiles with a dovetail-shaped longitudinal groove.
  • the rolling stock is regulated electrically brought to the desired rolling temperature before it enters the roll gap. In this way, the correct filling of the caliber of the rollers is to be ensured, so that the profile is fully developed and is true to size within narrow limits without burrs.
  • the auxiliary stand in this rolling mill is equipped with overhung roller rings. As the name of the auxiliary scaffold means, this scaffold is not suitable for rolling out rolling stock with large tapping cross sections and high forming resistances.
  • a rolling mill with several rolling stands standing in the rolling line for the production of rectangular, round or angular bars etc. is known.
  • the rod material is reduced during rolling in the roll nips of the roll stands by pressure and in the gaps or spaces between two adjacent roll stands by reducing the elongation.
  • the tensile stress of the bar between the roll stands is high and is in the order of the yield strength of the steel at the bar temperature and the rate of expansion.
  • Each roll stand consists of a module version.
  • Each module which has one half of the roll stand, comprises a housing, a shaft, a main bearing and a rear bearing.
  • the forces generated between the rolls are high during the rolling of flat profiles and angle profiles. These forces can cause the cantilever shafts to deflect.
  • an external bearing is installed on certain intermediate rolling stands within the rolling mill. This bearing is preloaded by hand.
  • the arrangement of a simple external bearing is in many cases not sufficient to absorb the high rolling forces if the reduction of the rolling stock is only to take place in the rolling stands and the reduction is not to be done by reducing the elongation.
  • the object of the invention is to further develop and improve a rolling mill consisting of CL stands in such a way that rolling stock with high tapping cross sections and high forming resistances and, if appropriate, rolling stock profiles can also be rolled with tolerable costs and short-time conversion measures.
  • This task therefore also includes an improved device for storing and for the rapid and largely automated changing of the rolling rings of the stands.
  • This task is solved with the measures of claims 1 to 7 in an exemplary manner.
  • the combined high-performance fine steel and wire mill of the type mentioned is characterized by the features of claim 1. If the rolling rings have to be replaced due to caliber wear or due to the rolling of another profile, this can be done in two ways: by exchanging the module unit known per se with an already pre-equipped module unit or, according to the invention, by changing the rolling rings, it being necessary to design the second bearing of the shaft carrying the roller ring in such a way that largely automatic removal of the roller rings is made possible with little maintenance.
  • an automatically actuated, preferably hydraulically acting, quick-action clamping device for the double-bearing roller rings with at least one piston-cylinder unit effective at least on one end face of the roller ring for clamping and releasing the same in the axial direction and at least one further piston acting on the roller ring.
  • the module unit with double-bearing roller rings has a cassette bracket which contains the second bearing and is arranged on the transmission cassette which contains the first bearing and which consists of two bracket parts which can be connected by a quick-release coupling.
  • the eccentric bush of the bearings of the shaft carrying the roller rings are positively connected with the aid of another connecting element, so that a synchronized turning of the eccentric bush is ensured.
  • the new rollers and the new rolling fittings are adjusted to the new rolling line with the aid of the positively connected eccentric bushes.
  • Figure 1 is the combined and continuously working high performance fine steel and.
  • the finishing train 3, which is the intermediate line in the wire production, is followed by the finishing block 4 with the cooling device 5 (not shown in more detail), usually consisting of a water cooling section with driver / winding layer and the Stelmor system.
  • the finishing train 3 is followed by a cooling or storage bed 6.
  • some roll stands can be arranged with a module unit 8 ', 8' with double-bearing roller rings 10 for the production of profiles as required. Since all gear, drive and housing units of the CL stands in the rolling mill can also be taken over in the intermediate line or finishing train, the module unit 8 ', 8' for profile production does not have to be part of the original equipment of the rolling train, but it If necessary, the CL module unit with overhung roller rings can be replaced with a module unit 8 ', 8' with double roller rings 10.
  • FIG. 2 shows the quick-clamping device for the double-bearing roller rings 10 of a corresponding module unit in the roughing mill and in the intermediate mill or in the finishing mill.
  • the quick release device 11 is arranged on the transmission cassette 12.

  • the second bearing 18 and the eccentric bushing 15 ' are located in a cassette bracket 19 which is connected to the gearbox 12, for example by means of a screw connection.
  • the cassette bracket 19 consists of two bracket parts, which are held together by a quick-release coupling 20.
  • the eccentric bushes 15 and 15 'of the first bearing 13 and the second bearing 18 are, as is known per se, positively connected, so that a synchronized rotation of the eccentric bushes is ensured with the aid of the meshing screw in the worm thread 16.
  • the removal and assembly elements of the quick-action clamping device 11 for the rolling rings 10, including the inlet and outlet guide fittings, which are not shown in detail, are to be designated as follows, starting at the end of the shaft 14: A compression nut 21 with a union nut 22. A retaining ring 23 which is arranged between the union nut 22 and a cylinder part 24. In the cylinder part 24, two annular pistons 25, 26 are arranged, namely a clamping piston 25 for the rolling ring 10 and a release piston 26 for the conical sleeve 27 on which the rolling ring 10 is seated.

  • the clamping piston 25 is then relaxed.
  • the release piston 26 for the cone sleeve 27 is hydraulically tensioned, whereby the element unit consisting of the cylinder part 24, support sleeve 28, cone sleeve 27 and walrzing 10 is pulled off the shaft 14. A separate puller is therefore not necessary.
  • the entire unit can Corresponding to the resulting center of gravity 9 of a crane unit, for example, by means of a transport bracket arranged on the cassette bracket 19, it is moved from the stand to a construction site on which new roller rings 10 are mounted and new fittings are attached and completely adjusted.
