Definitions
- the invention relates to a method for assembling and / or commissioning machine units in plants, such as machine foundations and / or rolling stands, for example in an existing production line of a hot-rolling mill, the prefabrication of the machine foundation and the prefabrication and pre-assembly or assembly of the required or interacting machine units on site next to the production line, whereupon these machine units are pushed into the production line as a complete structural unit including the foundation block.
- the foundations are created under difficult and time-consuming circumstances and usually have to be completed after installation of the facilities or exchanged for the final foundations with a lot of construction work.
- Document JP 63 03 01 07 A describes a roll stand with a special design in order to simplify a roll offset device with the aid of the installation of stand offset rails and of roll offset rails on the same horizontal plane.
- the document JP 59 04 50 10 A discloses a method and a device for exchanging stands of a rolling mill.
- the disposition Gap between the stands and at the same time the total length of the production line can be shortened by special offset of roll stand groups and by exchanging the stands.
- the document JP 11 31 99 05 deals with the task of preventing the formation of undulating patterns on rolled material and of avoiding an inadmissible lowering of the rolling temperature.
- a device for this purpose, a device is proposed in which a frame is provided with a base support on the corridor level, and is provided with a pressure control support, an inlet-side strain gauge, a middle strain gauge and an outlet-side strain gauge as well as an offset measuring stick.
- Finished roller units without housings are integrated in the frame and connected with an outlet-side strain gauge, with a connecting bolt and a stopper, in order to increase the strength.
- an offset device and a movement device for the finish-rolling units are advanced against the inlet-side direction by a movement cylinder, the intervals between the movement devices being increased.
- Document OS 2 018 383 describes a rolling stand, in particular for the deformation of a casting strand which runs directly out of a continuous casting installation, and the associated rolling mill installation. Because of the separate construction of the roll stands, the aim is to repair and maintain the stands away from the casting shop and to install the assembled roll stands and gear parts as quickly and easily as possible.
- the rolling stand is designed to be detachable from the foundation frame or the foundation plate with part of its gear mechanism and is designed to be removable from the latter or in the vertical direction.
- Document OS 2 018 490 relates to a roll stand for deforming a casting strand emerging from a continuous casting installation, with two roll stands, in which a horizontally arranged pair of rollers with its chocks is arranged to be vertically displaceable, the roller stands having a rigid cross connection at the bottom and a releasable cap connection at the top and the roll stand being releasably connected to a foundation plate.
- One problem with continuous casting plants is to arrange the rolling stands, with which the strands are further deformed after the casting operation, as space-saving as possible.
- the aim is to arrange the roll stands as close to one another as possible so that the distributor vessel and the one above the continuous casting molds are small in size and the temperature loss of the liquid steel can be kept as low as possible. It is also necessary to arrange the roll stands as close to one another as possible. Due to the low casting speed during continuous casting, the feed speed of the strand in the roll stands is considerably lower than with conventional roll mills, which would result in an undesirably high temperature loss if the roll stands were at a large distance.
- the gears interact with a vertical drive shaft driven from the underfloor, whereby after loosening the roll stand from the foundation plate, this including the gears and the drive shaft can be lifted and lowered vertically as a unit and thus the drive shaft with the arranged drive can be detached or is connectable.
- the document JP 58 09 03 05 A describes a method and a device for exchanging stands for a rolling mill. To improve the efficiency of the entire device, scaffolding placement frames are arranged on the side of a scaffolding chain and provided with two drive devices of different stroke lengths. Horizontal movement devices are also arranged on the sides of the new and old scaffolding on both sides of the frame.
- Document JP 62 14 48 10 A describes a construction which serves the purpose of reducing the number of stands which are to be kept ready and using the rolling stands in the unchanged state for a stand change, and only the other rolling stands to be replaced, which cannot be used as they are.
- the document JP 01 02 24 10 A describes a measure to reduce the number of stands to be kept available and to reduce the time required for changing them by selectively replacing only those stands which are required for the conversion of the rollers.
- the object of the invention is to provide a method for assembling and / or starting up machine units in systems by means of which substantial savings result from shorter assembly times or shorter assembly monitoring times during assembly, thereby reducing downtimes to reduce and to minimize the risk of construction work in the direct production rolling area.
- a statically determined mounting of the foundation block on at least two axes or displacement tracks is provided for the displacement.
- the shear lanes are made on, for example, pile foundations using gauges and flowing mortar, absolutely straight, level and parallel to each other, before the actual foundation block is produced. Accuracy requirements of +/- 1 mm based on a foundation block width of 7.34 m, for example, are observed.
- the sliding track has the entire length, which includes both the production line and the parallel waiting line, and is at least twice as long as the width of the foundation block, preferably the same width, and thus offers the option of presses over the entire length, as for the first stroke Raise the foundation block to replace individual bearing cushions or the stainless steel sheet sliding partner if necessary.
- bearing cushions on which the foundation block with the built-up machine elements for displacement rests, are connected to one another for example by means of frames and / or ropes and / or chains. They are drawn in between the bottom of the foundation block and the top of the sliding track before being moved and can also be replaced. Storage cushions and the various press types are available for exchange and replacement.
- a planned duration of three working days for moving and aligning is also sufficient for an accident in the production line.
- a technically possible displacement speed of 10 - 20 m / h and a displacement distance of approx. 10 m a pure displacement time of 30 to 60 min can be assumed.
- the foundation with the finishing stands is controlled away by means of a double press that communicates in pairs, raised to a height of approx. 5 cm and after the retraction Drained slideway and bearing in the same way.
- the foundation block on the plain bearings is first aligned horizontally using measurement marks in the roll stand axes.
- the vertical alignment takes place, whereby the same procedure is followed for lifting in the two shear axes.
- the first step of the fine adjustment takes place through the individually operated, communicating press pairs on the left or right side, each in a shift axis. height differences differences between left and right must not exceed specified values, for example 2 mm.
- the foundation is fine-tuned around a central axis by following the paired presses on the left and right of the central axis.
- the stages of fine adjustment described above can be continued until the required accuracy is achieved. Then the grouting is carried out with non-shrinking grout, which can be loaded after a few hours.
- An embodiment of the invention provides that a preliminary test run of the preassembled systems takes place on site before they are inserted into the production line.
- Another embodiment of the invention provides that the machine foundations in the assembly area of the foundation block to be moved are partially or completely created as a precast reinforced concrete element, so that they can later be used as foundations for new machine foundations.
- a further embodiment of the method provides that the foundations of the roll changing area are at least partially constructed and installed as prefabricated reinforced concrete parts.
- Figure 1 is a perspective view of a prefabricated foundation block with finishing stands before insertion into the rolling line;
- Figure 2 and further in perspective views of the foundation blocks with the finishing stands in the final position (in the production line);
- Figure 3 is a top view of the sliding tracks with lifting points / lifting surfaces;
- Figure 4 is a top view of the sliding tracks with foundation block in the waiting line
- Figure 5 is a top view of the sliding tracks with a foundation block in the production line.
- the number 1 denotes a foundation block
- the number 2 completely assembled roll stands and the number 3 the course of a fictitious waiting line.
- the finishing stands - in the present case there are three stands - are assembled and, if necessary, run in trial operation.
- the original production line 4 is operating undisturbed.
- the foundation block 1 lies on two parallel sliding tracks 5, which preferably run at right angles to the production line 4 and the waiting line 3 and are arranged in an intermediate space 8.
- An abutment 6 is provided on the opposite side of the production line 4. This can consist of an existing system part or can be specially manufactured.
- the pulling devices On the rear side (not shown) of the abutment 6 are the pulling devices provided for the displacement, which are connected to the foundation block via pulling means 7 (not shown).
- Figure 2 shows that after completion of the prefabrication and / or pre-assembly or final assembly of the now ready-to-use scaffolding 2, the foundation block 1 with the scaffolding 2 is inserted into the production line 4 and the scaffolding are immediately integrated into the production process.
- FIG 3 the sliding tracks 5, which are arranged in an intermediate space 8 of the existing system, are shown in plan view. While in the waiting line 3 on the sliding tracks 5 two lifting points / lifting surfaces 9 are provided, two further lifting points / lifting surfaces 11 are installed on the central axis 12 of the foundation block 1 in addition to the lifting points / lifting surfaces 10 for the alignment of the foundation block 1 in the production line 4.
- the lifting points / lifting surfaces 9, 10, 11 can also be doubled if necessary in order to distribute the load more evenly.
- Steel plates of size 500 x 500 x 80 for example, are installed as lifting points / lifting surfaces 9, 10, 11.
- the foundation 1 with the upright scaffolding 2 is then created or set up in the waiting line 3, as shown in FIG. 4 in plan view.
- the shifting into the production line 4 takes place via traction means 7, the traction devices 13 being supported on an abutment 6.
- the foundation block 1 with the upright stands 2 is aligned horizontally by means of presses 14, 15. Then the foundation block 1 is raised, the slide bearings removed and the whole thing lowered / lowered and aligned vertically. Subsequently, the intermediate space 8 is formed, for example, as a roller exchange area.
- the sliding tracks with the foundations can be used as foundations for new machine foundations. Individual parts or components can be made from precast reinforced concrete.
