Definitions

  • the invention relates to a combined, continuously working high-performance fine steel and wire mill, each with a plurality of roll stands or rolling units having a roughing mill, at least one intermediate mill and subsequent finishing mill with a subsequent finishing block, if appropriate.
  • the vertical scaffolding are driven from below.
  • a preliminary gear is arranged between the motor and the scaffold, which is designed as a bevel-helical gear in the vertical stands and as a helical gear in the horizontal stands.
  • the drive shaft drives the auxiliary shaft and one of the two roller shafts at the same time.
  • the other roller shaft is carried over the auxiliary shaft.
  • the drive shaft and the countershaft like the roller shafts, are highly tempered and ground.
  • the roller shafts run in plain bearings that are inserted in rotatable eccentric bushes.
  • the rolling rings are turned on at the same time, by turning the eccentric bushing via a threaded adjusting screw in the opposite direction of pitch.
  • the caliber line remains constant.
  • the rolling pressure exerted by the rolling stock basically goes into the first bearings of the overhung rollers.
  • the rolling rings, the bearings and the housing have to be dimensioned appropriately large when rolling with high tapping cross sections and high forming resistances.
  • the compact design of the CL scaffolding can be largely lost.
  • the intermediate line or the finishing train of a wire and fine steel mill consisting of CL stands is not designed to also roll profiles, since this can generally lead to dimensional inaccuracies due to the flying bearing of the rolls. 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.
  • 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 piercing cross-sections and high forming resistances and optionally also rolling stock profiles can be rolled with tolerable costs and short-time conversion measures with this rolling mill.
  • This task therefore also includes an improved device for storing and for the rapid and largely automated change of the rolling rings of the stands.
  • This object is achieved in an exemplary manner with the measures of claims 1 to 19.
  • the combined high-performance fine steel and wire mill of the type mentioned above is characterized in that in the roughing mill and in the intermediate mill and / or the finishing mill, a rolling mill consisting essentially of CL stands with overhung rolling rings has a few rolling stands with one Module unit with double-bearing roller rings are arranged.
  • the CL module unit with overhung roller rings can be exchanged for a module unit with double bearing roller rings in some stands in the roughing mill and in the intermediate line and / or in the finishing train.
  • the cassette unit with the two-sided roller rings can then be selected instead of the CL module unit with single-sided rollers if necessary and in line with the tapping cross-sections, the rolling forces and the rolled profile. All gear, drive and housing units of the CL stands in the rolling mill can be taken over will. In this way, cassette types or cassette sizes with different center distances can also be used.
  • the module unit with double-bearing roller rings for profile production does not have to be part of the original equipment of the rolling line, but can be retrofitted if necessary.
  • the CL module unit with roller rings mounted on one side can be easily replaced with a module unit with double roller rings if, for example, small batch sizes are also to be manufactured to expand the program.
  • the module unit with double-bearing rolling rings can also be used for the two-core finish rolling of split, i.e. cut-rolled round material, e.g. can be used particularly advantageously for the production of reinforcing steel.
  • the rolling rings are equipped with two calibres. Furthermore, it is expedient to provide a horizontal / vertical arrangement of the overhung roller rings and the double roller rings between the stands, as a result of which the twisting of rolled round material between the stands is avoided.
  • 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 replacing the module unit with an already pre-equipped module unit as previously suggested or after a further development of the invention by changing the rolling rings, whereby it it is necessary to design the second bearing of the shaft carrying the rolling ring in such a way that largely automatic removal of the rolling rings is made possible with little maintenance.
  • an automatically operable, preferably hydraulically acting quick release device for the double-bearing roller rings proposed, with at least one piston-cylinder unit effective at least on an end face of the rolling ring for clamping and releasing the same in the axial direction and at least one further piston-cylinder unit effective for clamping and Loosen in the radial direction of a cone bushing that supports the rolling ring and is displaceable on its shaft axis.
  • the module unit with double-bearing roller rings has a cassette bracket containing the second bearing and arranged on the gearbox cassette containing the first bearing, which consists of two bracket parts which can be connected by a quick-release coupling.
  • the eccentric bushes 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 bushes 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.
  • the advantage of the structural design of the quick release device according to the invention for the double-bearing roller rings of the module unit is described below. If the overhung rolling ring of the CL stands is to be exchanged for a double bearing rolling ring either in the roughing mill or in the finishing stands of the intermediate line or finishing mill, the entire module cassette will be replaced. With the proposed construction, the cassette change and the change of the roller rings can be carried out in a very short time and largely automatically. Depending on the application, the rolling mill can therefore be most cost-effectively complete with CL stands or in the roughing train with some stands with modular units with double Roll ring storage and in the intermediate line and finishing train can be equipped with module units with double roller ring bearings for profile rolling or separating rolling either during the initial configuration or later.
  • the module unit is designed with an interchangeable roller cassette in a sandwich construction, essentially consisting of two at least one-piece rolling ring shafts carrying cassette plates and their bearing units and adjusting units with coupling pieces at their ends angled and facing each other.
  • the cassette front plate of the roller cassette can be changed separately if necessary, optionally together with the roller rings and / or with the roller fittings. Since in the present case the cassette front plate can be replaced separately, the rolling ring cooling and other hydraulic connections can be expediently arranged on the cassette plate that can be connected to the gearbox cassette.
  • the construction of the claimed roller cassette in a sandwich construction allows, according to a further development of the invention, a simple fastening of the roller rings on the roller ring shafts, which is characterized in that the roller rings are seated on a conical sleeve pushed onto the roller ring shaft, which is used for clamping and releasing the roller rings is subjected to the axial pressure of a hydraulic nut in the radial direction.
  • the rolling rings are advantageously held between annular clamping pieces, which have a friction disc connection rest on the side flanks of the roller rings;
  • the clamping pieces are expediently splined with the conical sleeve or the rolling ring shaft.
  • 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 with a module unit 8 ', 8''with double-bearing roller rings 10 for profile production can be arranged as required. Since all gear units, drive units and housing units of the CL stands in the rolling mill can also be taken over in the intermediate mill or finishing mill, the module unit 8 ', 8''for profile production does not have to be part of the original equipment of the rolling mill, but instead if necessary, the CL module unit with overhung roller rings can be exchanged for 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 first bearing 13, preferably a multi-layer slide bearing of the shaft 14 of the rolling ring 10, is seated in an eccentric bush 15, which also has an adjusting spindle (not shown) Worm thread 16 is rotatable.
  • Worm thread 16 is rotatable.
  • the shafts 14, 14 'carrying the rolling rings 10, 10' are driven with the help of spur gears 17, 17 'driven by a preliminary gear, not shown.
  • the second bearing 18 of the rolling ring 10 is also a multi-layer slide bearing, which is arranged in an eccentric bush 15 '.
  • the second bearing 18 and the eccentric bushing 15 ' are located in a cassette bracket 19 which is connected to the transmission cassette 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 adjusting spindle meshing in the worm thread 16.
  • the removal and assembly elements of the quick-action clamping device 11 for the roller 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 cylinder part 24 is positively and non-positively connected to a support sleeve, on the support surface 29 of which one end face 30 of the rolling ring 10 rests.
  • the second multilayer plain bearing 18 is arranged on the support sleeve 28 and from the eccentric bushing 15 'surrounded.
  • the eccentric bushing 15 ' is arranged in the cassette bracket 19, as said.
  • thin friction disks 38 are inserted for torque transmission .
  • the stop ring 32, the conical sleeve 27 and the support sleeve 28 are arranged in a form-fitting manner in the circumferential direction, preferably by means of a longitudinal toothing 34, 35 or the stop ring with a feather key 36 on the shaft 14 carrying the roller ring 10.
  • an annular piston 37 which is supported against the conical sleeve 27 for the purpose of clamping the conical sleeve against the rolling ring.
  • the cassette bracket 19 is first unlocked from the transmission cassette with the aid of the coupling 20.
  • Centering units arranged on the gearbox cassette are hydraulically tensioned and the centering bolts retained for compression by means of compression springs are advanced and then the bolts are pivoted out of the centering bolts by hand (not shown in more detail).
  • clamping piston 25 for the rolling ring is hydraulically tensioned higher and the pressure nut 22 loosened and screwed back.
  • 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 in accordance with the resulting center of gravity 9 of a crane unit, for example by means of a transport bracket arranged on the cassette bracket 19, are moved from the stand to a construction site on which new rolling rings 10 are mounted and new fittings are fastened and completely adjusted.
  • the assembly is moved from the construction site to the rolling stand 7 with the aid of a crane or a quick-change device and is pulled onto the roller shaft 14.
  • the assembly is carried out as follows: the pressure nut 21 is rotated in the closing direction and the assembly is pushed onto the shaft 14 centering.
  • the annular clamping piston 37 for clamping the cone sleeve 27 and the annular release piston 26 for the cone sleeve 27 are hydraulically relaxed. Now the clamping piston 25 is tensioned for the rolling ring, so that the rolling ring is pressed against the stop surface 30 of the stop ring 32 via the support surface 29 of the support sleeve 28.
  • the ring piston 37 for clamping the conical sleeve 27 is hydraulically preloaded and inserted.
  • the clamping piston 25 for the rolling ring 10 is then pretensioned to maximum pressure and the union nut 22 is tightened by hand to the stop.
  • the cassette bracket 19 is locked by means of the latch pivoted into the centering bolt by hand. Now the centering unit is hydraulically relaxed, whereby the centering bolts are pushed back with the help of the compression springs and thus take over the clamping of the cassette bracket.
  • the new rollers and the new roller fittings are adjusted to the new caliber opening with the aid of the positively connected eccentric bushes 15, 15 '.
  • FIG. 3 and FIG. 4 show a further module unit 8, 8 ', 8''with an exchangeable roller cassette 40 which is designed in a sandwich construction.
  • the roller cassette consists of two cassette plates 44 with coupling pieces 45 which end at one end and point towards one another.
  • the rolling ring shafts 41 are carried in bearings 42 in the cassette plates.
  • the shaft ends of the rolling ring shafts 41 can be inserted into the transmission cassette 47, which is no longer shown.
  • the hydraulic nut 50 can be seen, with which the rolling ring 46 is fastened on the shaft 41 in the radial direction with the aid of a conical bush 49 pushed onto the rolling ring shaft.
  • the adjusting unit 43 for setting the roller rings 46 to the respective caliber opening is arranged on the outer sides of the cassette plates 44.
  • the bearing units for the rolling ring shaft, in this case spherical roller bearings, are arranged in the eccentric bushing 57.
  • the eccentric bushing 57 is forcibly connected on the transmission side by means of the connecting shaft 55 to the other actuating unit 43 which is arranged on the cassette plate 44 which faces the transmission cassette 47.
  • FIG. 3 also shows that the entire roller cassette 40 can be pulled off the gear cassette 47 and can be exchanged for a new cassette, possibly for a different cassette type or a different cassette size with different center distances.
  • Figure 3 also shows that the cassette front plate 44 of the roller cassette 40 can be replaced separately if necessary, if necessary with the roller rings 46 and / or the roller fittings.
  • the screws of the coupling piece 45 are loosened or removed and the hydraulic nut 50 is relaxed and loosened. Since the roller ring 46 is seated on the conical sleeve 49, this is also removed from the roller ring shaft when the cassette front plate is removed. Then the rolling ring 46 is easily accessible and can be easily removed from the taper bush 49 and exchanged for a new rolling ring.
  • the roller rings 46 are seated on a conical bush 49 pushed onto the roller ring shaft 41, which is acted upon in the radial direction by clamping and releasing the roller rings with the axial pressure of the hydraulic nut 50, the mode of operation of which is assumed to be known. So that the rolling rings 46 not only in radial direction on the rolling ring shaft 41, but also axially and in the circumferential direction, the rolling rings are held between annular clamping pieces 51, friction disks 52 being inserted as connecting elements between the clamping pieces 51 and the side flanks 53 of the rolling rings, and furthermore the clamping pieces 51 with the Taper bush 49 or on the other side are splined with the rolling ring shaft 41.
