Definitions
- the invention relates to a method and a system for rolling strip-shaped rolling stock, in particular metal strip, consisting of at least one reversing rolling mill and at least one reel arranged in front of it and a reel for winding up or unwinding the rolling stock, a welding device and a strip storage device.
- the rolled material In order to achieve the acceptance of rolled material to the finished thickness, the rolled material has to go through this several times in the case of individual stands. If several rolling stands are built one behind the other to form a tandem mill, the rolling stock need only pass through the tandem mill once. The reduction in the thickness of the rolling stock from the raw dimension to the finished dimension determines the number of mill stands installed. Contistrassen are a further development of tandem streets. Here, the strip end of the rolled material of one coil is connected to the strip start of the next coil, for example by welding. The advantage of such a system or method is that there is no need to thread the rolling stock from each coil, the rolling stock is endlessly available to the rolling train.
- BESTATIGUNGSKOPIE established a method and a device in which the rolling stock passes through one or two roll stands several times without the rolling stock leaving the roll gap.
- the rolled material wound into a coil is passed from a decoiler through one or more roll stands and wound onto another coiler.
- the rolling stock is shaped in the back and forth between the adjustable rolls.
- DE 43 10 063 A1 discloses a system for cold rolling strip-shaped rolling stock with a reversing stand arranged between two reversing reels and a reel from which the insert strip can be unwound.
- Such a system can also only be operated economically with high throughput.
- the invention is therefore based on the object of providing a method and a system, taking into account at least one reversing rolling mill, in order to offer economical processing of rolled material.
- This object is achieved according to the invention by a method in which the metal strip is wound onto the decoiler during the reversing stitches and a further strip start of another metal strip is welded onto the strip end of the metal strip before the last pass.
- a system according to the invention provides that the decoiler for the reversing stitches is used as a tape store.
- Embodiments of the invention are specified in the subclaims.
- one of the two decoilers can simultaneously function as the decoiler of an upstream pickling line. In this way, an expensive transport of the individual coils is avoided, with damage to the coils no longer occurring due to the transport.
- the pickling line can also be integrated into the system, for example between the welding machine and the reversing rolling mill.
- An adapted, larger tape storage device must be provided for this.
- FIG. 1 shows an illustration of a two-stand reversing line according to the invention with a welding device, a strip storage device and a reel and take-up reel.
- a reverse or reversing street is shown in the single figure.
- a metal strip 3 is unwound from a coil 2 on a decoiler 1 and passed through a welding device 4, a strip store 5 and a roll stand 8 and fed to a decoiler 9 for the first roll. zen of the coil.
- Another coil 7 is kept on a further decoiler 6.
- the strip store 5 is opened in order to bridge the time span for the welding of the strip end of coil 2 with the strip start of coil 7 for further rolling.
- the metal strip 3 can be rolled out from coil 2 to the weld seam and a few meters beyond.
- the assembled metal strip 3 is alternately wound onto the reel 6 and the reel 9.
- the following coil is already positioned on the decoiler 1 in order to be welded to the end of the metal strip 3 by coil 7.
- the metal strip 3 When the target thickness is reached, the metal strip 3 is wound on the take-up reel 9 to form a coil 10 of a predetermined length. For this purpose, the metal strip 3 is cut. After the finished coil 10 has been removed from the take-up reel 9, the remaining metal strip 3 is connected to the take-up reel 9. At the same time, a further metal strip 3 is welded in the welding machine 4 by a coil 2 or 7 of the decoiler 1 or 6 to the non-deformed metal strip 3 remaining in the strip store 5. Subsequently, without further interruption, the next length of the metal strip 3 is deformed further.
- so-called jumbo coils each with two or more normal coils connected to one another
- the prerequisite for this is that the metal strips of the coils have the same dimensions.
