Definitions

  • the invention relates to a rolling mill, in particular a rolling mill in a shaped steel rolling mill with at least one stand group consisting of n stands in a group, the stand having at least horizontal guide fittings which are arranged at least on the middle stands in a rolling line with a close spacing from one another.
  • the invention also relates to a method for controlling the stand change in said rolling mill
  • the overall technical concept for the economic efficiency of the rolling mill is decisive for the rational production of steel profiles of different shapes and sizes in combined shaped steel rolling mills, in particular largely mechanized change systems for the roll stand, rolls and roll stand fittings are decisive for an inexpensive adaptation of the rolling train to different rolling programs with different lot sizes .
  • the object of the present invention is to be able to adapt a rolling mill of the type mentioned at the outset to the various rolling programs even more efficiently, primarily by means of extensive mechanization of the roll change and change of fittings on the roll stand, in order to reduce the time and manpower required for the staff when changing the roll To reduce the risk potential and to do without interchangeable scaffolding.
  • every second roll stand from the rolling line is designed to be displaceable, movable or displaceable at least by the width of the guide fitting from the stand for the purpose of changing the guide fittings and / or the rollers;
  • the adjacent roll stands can be arranged in a stationary manner in the rolling line. For example, from a group of scaffolds consisting of three roll stands, the middle stand is shifted to the operating side to such an extent that sufficient assembly space is created to remove the guide fittings from the roll stands or to mount new guide fittings on the roll stands.
  • the upsetting scaffold is designed to be displaceable at least half the width of the universal scaffolding on the operating side.
  • the smallest scaffold, the compression scaffold from a scaffold group with two heavy universal scaffolds is also only moved to the operating side as far as the limited space between the two heavy duty universal scaffolds make this necessary.
  • the compression frame has reached a sliding position that is outside the half width of the universal frame, the compression frame is easily accessible from all sides and the guide fittings can be changed quickly and easily.
  • the compression frame can be moved from the rolling line to the operating side on rollers having its own drive.
  • the displacement path of the roll stand can be traversed quickly without the need for special displacement rods or displacement hydraulics.
  • the chocks of the roll stands which support the horizontal rolls, can be displaced from the compression stand or from the universal stand on rollers having their own drive.
  • the rolls stored in the chocks can be moved from the roll stands to a separate construction site without great expenditure on equipment.
  • new rolls can be inserted and set in the roll stands just as quickly and easily.
  • new or adapted guide fittings can be mounted quickly and easily. It becomes clear that through these measures, the assembly effort is reduced considerably and that expensive interchangeable scaffolding can be dispensed with.
  • the compression scaffold have at least one movable assembly platform on the drive side. It is expedient that the assembly platform has a platform length in the rolling line which corresponds approximately to the distance between the universal stands and that the platform width corresponds approximately to the displacement path of the compression frame. This measure allows the pulling of the guide fittings from both universal stands from an assembly platform, since the assembly platform is inserted between the universal stands to the extent that the compression stand is moved out of the rolling line. The assembly of the new guide fittings on the universal scaffolding is also carried out in a particularly favorable manner from the assembly platform.
  • a stationary working platform is arranged on both sides of the displaced upsetting frame on the operating side, so that the removal of the guide fittings from the upsetting frame and the fitting of the upsetting frame with new fittings can take place in a particularly favorable manner, at the same time, for which the fittings are changed on the universal scaffolding.
  • the assembly platform and the working platform have at least one set-up, consisting of at least one guide fitting pre-assembled in a stand and a preferably adjacent empty stand.
  • This measure means that the time for changing the fittings is again reduced shortens, especially if the guide fittings are pre-assembled on the assembly platform.
  • the guide armatures on the assembly or working platform can be dismantled with the help of the empty stand and immediately afterwards the pre-assembled guide armature can be inserted into the rolling stand, the empty stand being designed, for example, as a movable carriage.
  • a further rationalization of the change of fittings in a group of rolling stands is achieved in that, on the assembly platform and on the work platform, preferably automatically operable pulling devices or assembly devices for the guide fittings are arranged, so that the use of personnel in the safety-threatening zones can be considerably restricted .
  • the upsetting stand be connected to at least one position transmitter which limits the displacement path in such a way that the empty stand on the assembly platform is the guide armatures of the universal stand and that the empty stand on the working platform can be fed to the guide fittings of the edging stand approximately in the center.
  • the compression frame with little at least one position encoder limiting the displacement path is connected in such a way that the guide fitting pre-assembled on the assembly platform can be fed to the universal stand in the rolling line and the guide fitting pre-assembled on the work platform can be brought to the compression stand approximately in the middle.
  • the method for controlling the stand change in a rolling mill is characterized according to the invention in that the upsetting stand is moved step by step from the rolling line and that the position transmitter is first actuated for the empty stand position for the purpose of dismantling the guide fittings from the roll stands and that the position transmitter is then actuated for the preassembly position for the purpose of installing the preassembled guide fitting on the roll stands before the upsetting stand is moved back into the rolling line.
  • the valve exchange can be largely automated in a scaffold group, e.g. in a universal carrier line, so that the time required for changing the guide valve in the scaffolding from usually one hour to about ten minutes.
  • the position transmitter for the empty stand position releases the lock for the rollers of the roll stands stored in the chocks and the position transmitter for the preassembly position closes the lock.
  • a fully automatic changing system for the rollers and for the guide fittings in a stand group is created, in particular in connection with driven chocks, whose hydraulic drives, for example, are switched on or stopped depending on the locking of the chocks in the rolling stands.
  • a roller conveyor 6 which transports the rolling stock, for example a T-shaped support, is arranged on both sides of the universal stands 2, 3.
  • the horizontal rolls 9 are stored in chocks 8.
  • the guide fittings 10 guiding the rolling stock are arranged in the area of the roll gap between the horizontal rolls.
  • the chocks 8 carrying the horizontal rollers are mounted on rollers 11 which have their own drive, the drive e.g. can be a commercially available hydraulic wheel hub drive.
  • the upsetting frame 1 and the universal frames 2, 3 are of the same type with regard to these components, which is why the same reference numbers should apply to these components.
  • the compression frame 1 is mounted on support rollers 12 which have their own drive.
  • This roller drive like the roller drive on the chocks 8, can consist of a commercially available hydraulic wheel hub drive.
  • the upsetting frame 1 and the universal frames 2, 3 are arranged on sole plates 13, which in turn are connected to the foundation 14.
  • the rolling stands within the stand group 4 are at such a short distance from one another that their guide fittings seem to touch in the rolling line in order to give the rolling stock an uninterrupted guidance.
  • the guide fittings 10 can be seen disassembled from the puller 15.
  • Fig. 2 shows a plan view of the scaffold group 4 consisting of universal scaffold 2, compression frame 1 and universal scaffold 3 in a reduced view. It can also be seen here that the guide fittings 10, seen in the rolling line 16, are at a very close distance from one another.
  • the upsetting frame 1 has on the drive side 17 a mounting platform 18 which can preferably be moved together with the frame.
  • the assembly platform has a length L which corresponds approximately to the distance between the universal scaffolding 2, 3.
  • the width B of the assembly platform corresponds approximately to the displacement path of the compression frame.
  • the universal stands 2, 3 of the stand group 4 are arranged in a stationary manner in the rolling mill 5, while the upsetting stand 1 can be moved out of the rolling line 16 to the operating side 19.
  • the shifted position of the compression frame is shown in Fig. 2 in dashed lines. It can be seen that the compression frame is displaced from the roller line by about half the width U of the universal frame 2.
  • a work platform 18 ' is located on both sides of the displaced compression frame 1'.
  • a respective set-up group 20 for the guide fittings 10 of the universal stands 2, 3 is installed opposite the respective universal stands 2, 3.
  • the setup group 20 for the assembly and disassembly of the guide fittings 10 and their support 10 ' consists of an empty scaffold 21 for a guide fitting (dashed lines) and a pre-assembled guide fitting 22.
  • a setup group 23 is arranged , which contains a guide fitting 24 pre-assembled in a frame for the compression frame 1 and a corresponding secondary empty frame 25.
  • a site 26 is set up on which the roller sets 27, 28 for the universal stands 2, 3 and the roller set 29 for the upsetting stand 1 are prepared.
  • the roller sets 27, 28, 29 of the stand group are displaced from the roll stands on a sliding platform provided with rails 30 to the site 26 or transported from the site 26 to the roll stands. The displacement of the rollers sets are made with the help of own roller drives 11.
  • the empty stands 21 stand on the assembly platform 18 in the longitudinal direction of the guide fittings 11 the universal stands 2, 3 and the empty stand 25 on the work platform 18 'is in the longitudinal direction to the guide fittings 10 of the upsetting frame 1.
  • the guide fittings from the universal stands and, at the same time, the guide fittings can be moved out of this position of the upsetting frame the edger are removed and placed on the assembly platform 18 or on the work platform 18 '.
  • the shifted assembly position of the compression frame 1 is shown in Fig. 3. From the pullers 15 and assembly devices 15, the guide fittings 10 on the work platform 18 'disassembled or mounted on the chocks 8 can be seen.
  • the rollers 9 of the universal stands 2, 3 can be moved along the work platform with the aid of the roller drive 11.
  • the position sensor 31 can release the lock, not shown in more detail, for the rollers of the roll stands stored in the chocks 8, so that the roller sets can be opened by means of the driven rollers 11 the rails 30 of the transfer platform can be moved to the site 26. From the building site 26, the new roller sets assigned to the respective roll stands are moved into the roll stands on the rails 30 of the transfer platform and adjusted there in a known manner.
  • the upsetting frame is moved with the aid of the idler roller drive 12 into a new mounting position, which is controlled by the position transmitter 32 so that the guide fitting 22 preassembled on the mounting platform 18 is brought approximately centrally to the universal stands 2, 3 and at the same time that on the working platform 18 'pre-assembled guide fitting 24 is approximately in the middle in front of the rollers of the compression frame.
  • the preassembled guide fittings 22, 24 are connected to the upsetting frame 1 or to the universal stands 2, 3 with the aid of the automatically operated assembly devices 15.
  • the respective locking of the roller sets in the roll stands can be controlled by the position transmitter 32.
  • the upsetting stand 1 is moved from the operating side 19 back into the rolling line 16, so that the entire stand group is set up to roll a rolled product with a changed profile shape.
