Definitions
- the invention relates to a rolling mill for rolling metallic Guts, which has min ⁇ least one rolling stand and a both sides of the roll stand over a predetermined length extending conveyor line for the material to be rolled.
- Rolling plants of the generic type are required, for example, for the production of aluminum sheet.
- the sheet is produced in a multi-stage process in which initially takes place a hot rolling of the slab. If this is sufficiently rolled out and if necessary heat-treated, the sheet is cold-rolled to the final thickness. Both hot rolling mills and cold rolling mills are customary for this purpose and adequately described in the prior art.
- WO 98/53111 discloses a process for the production of hot-rolled aluminum cans, the process in particular being intended to be suitable for lower production quantities of less than 250,000 1 per year.
- a reversing pre-rolling of the hot-starting material is first provided on a hot rolling plant, followed immediately by a finish rolling of the strip, which is followed by a heat treatment of the strip wound up into a coil.
- the recrystallization in the rolling stock is suppressed by controlled temperature control of the hot strip and the recrystallization is brought about deliberately only in direct connection to the finish rolling outside the rolling train.
- WO 96/10655 and WO 96/10656 relate to a manufacturing process for aluminum sheet. Again, hot rolling of the slab or the strip produced by the rolling process takes place first on a hot rolling mill. would. Then, a heat treatment process is performed, and finally, a cold rolling operation is performed on a cold rolling mill.
- the hot rolling mill and the cold rolling mill fundamentally differ in this respect, because the hot rolling mill on both sides of the roll stand requires a conveying path extending over a predetermined length for the material to be rolled.
- the slab is first introduced into the plant and rolled out. As a rule, a reversing process takes place, d. H. the slab, which is becoming ever thinner due to rolling, moves back and forth through the roll stand. After completion of the hot rolling process, the rolled strip is wound on a reel to a coil or bundle.
- the already prepared coil is brought into the system.
- the rolling stand is located between two reels. From the one reel the tape is unwound from the coil and fed to the nip. On the other side, the cold-rolled strip is fed to the other reel and wound up into a coil.
- the invention is therefore based on the object, a rolling mill of the type mentioned in such a way that the said disadvantage does not occur and it comes to a more profitable use.
- the solution of this object by the invention is characterized in that in the region of the longitudinal extent of the conveying path at least one receiving device for a coil of the metallic Guts is arranged, which can be arranged in a first position in which they the conveying of the metallic Guts along the conveyor line is not hindered, and can be arranged in a second position in which it positions the coil near the rolling stand on the conveyor line for winding or winding of the coil.
- the invention thus provides that measures are taken to make a hot rolling mill suitable for carrying out the cold rolling process.
- the recording device for a coil which is not required during hot rolling, is arranged below the roller conveyor, for example, and is not used during hot rolling.
- the pick-up device is moved into the working position, so that cold rolling can also be carried out on the hot rolling plant. The efficiency of the rolling mill is thereby substantially increased.
- the at least one receiving device is arranged on a lifting device with which it can be positioned in the vertical direction at the desired height.
- at least one guide belt in particular a driven belt guide roller, is arranged on the lifting device. This is needed for the cold rolling because the strip to be rolled must be deflected from the reel to the horizontal before the strip is fed to the Waiszalt. It is particularly advantageous if the at least one tape guide roller is arranged in the lowered position of the lifting device at the level of the other rollers of the conveyor line. It then fulfills a function during the hot rolling process.
- a heat trimming scissors is further provided, which is provided with Verschiebe ⁇ means, in particular lifting means, with which they in working position (for hot rolling) or driven out of this (for cold rolling).
- the band support and / or band drive and / or band straightening means are preferably a previously known Bridler roller combination, in particular a 4-roller Bridler roller combination, with an attached driver.
- At least one cooperating with the Ba ⁇ d Operationssrolle counter-roller can be provided, which is displaceable in the vertical direction and can be positioned at a predetermined height.
- means for exchanging the rolls of the roll stand are preferably provided, with which the replacement of the rolls can be carried out or at least supported.
- the rolling mill can be used for both rolling processes, a further development provides that the installation has means for supplying the rolls of the rolling stand and / or the material to be rolled with a coolant and / or lubricant, these means optionally being used for supply are switchable with rolling oil or for supply with emulsion.

- the receiving device - shown in solid lines - is in the lowered position; dashed lines indicate which position the receiving device 5 and the coil 6 occupies during cold rolling.
- the hot rolling position is indicated by A (first position) while the cold rolling position is indicated by B (second position).
- a tape guide roller 8 is further arranged, which is shown only very schematically. This role moves when lifting the receiving device 5 for the coil 6 up or down with. Da ⁇ in the system is designed so that the tape guide roller 8 is in its lowered position exactly equal to the other rollers 9 of the conveyor section 4, d. H. In this position, it also serves to move the slab 2 back and forth.
- the sliver guide roller 8 is also shown in solid lines in the position (A) which is assumed during hot rolling, while the dotted lines represent the Position taken during cold rolling (position B).
- a heat trimming shears 10 is usually required, which is arranged on displacement means 11, with which they can be moved vertically and in their respective position (A, B) can be driven. Again, the position A designates that of hot rolling and position B that of cold rolling.
- the Beklamschere 10 in Fig. 1 during hot rolling in its working position, while it was driven out of engagement during cold rolling.
- FIG. 2 shows a counter roller 14, shown schematically for cold rolling, which can be driven into working position by means of movement, not shown.
- the counter roller 14 cooperates with the tape guide roller 8 and provides a guide and, if necessary, a drive of the cold roll 2 to be rolled.
- the rolling mill described can be converted within a short time (within a few hours) from the equipment for hot rolling to that for cold rolling and vice versa.
- the economy of the system is thus in the given case, d. H. in the absence of full utilization for one rolling type, considerably increased.
- a station for preparing the coils to be cold rolled (coils) may include a lifting chair, a roller truck, a neck opening table, a driving roller and straightening roller unit, a cropping shear, a base frame with scraping trash, a scrap bucket together with a track, a bunch pliers, and a center collar centering and elevating station exhibit.

Then the drain is opened in the new collection chamber for used flushing oil. After switching on the system pump of the rolling oil system, the nozzle bar and, if necessary, the scaffold pan are also flushed with rolling oil via a flushing connection. Contaminated wash oil is provided via the collecting chamber by means of return pumps to the container for used flushing oil in the new rolling oil building. Finally, the return to the return pump tank for rolling oil is opened.
- the grip beam is first blown out by means of compressed air. Then the return to the return pump tank for rolling oil is closed after a corresponding dripping time. Then the residual emptying connection at the return for rolling oil is opened. After closing the residual discharge connection at the return for rolling oil, the return is opened to the emulsion return pumping container.
- the reversing valves in the return lines and the residual emptying are designed as manual valves with end position monitoring.
- the Um ⁇ switch fittings in the flow lines on the scaffold are designed as pneumatically betä ⁇ ended fittings with end position monitoring.
