Definitions
- the invention relates to methods for producing a hot reversely rolled strip, in particular a steel strip, a strip being cast either directly or by continuous casting is produced by continuous casting and subsequent roughing, then the strip in hot rolled several passes and wound into a bundle after each pass is, as well as a device for performing the method.
- a method for reversing rolling a hot strip is, for example, also in the DE-A-29 00 648.
- the tape is applied after each Roll pass by a winding device designed as a reel furnace.
- a winding device designed as a reel furnace.
- a hot rolling process of this type and the type described at the outset result temperature differences between the strip ends and strip edges during rolling and belt middle parts.
- temperature compensation is to the extent that the strip ends or strip edges in turn are not too ideal from the ideal rolling temperature very different temperature, not possible, as this is a longer break between would require two successive roll passes, i.e. the rolling process would have to to be interrupted.
- Inadequate use of the reversing roller device as well The result would be a decline in production.
- the invention aims at avoiding these disadvantages and difficulties and presents itself the task, a method of the type described above and a device for To carry out the process, which make it possible, in combination with the Production of a strip in a continuous caster on the one hand the reversing roller device to make the best possible use over their entire service life, i.e. a rolling mill without Maintain interruptions and without loss of production volume and yet optimal for the strip to be rolled while saving as much energy as possible To achieve temperature conditions. Furthermore, temperature differences between the Tape ends and the tape edges and tape center pieces are kept so low that they neither for the rolling process, for the rolling devices, nor for the quality of the strip have adverse effects.
- This object is achieved according to the invention in a method of the type described in the introduction solved in that two or more strips are alternately rolled and during the Rolling one of the strips in at least one roll pass the other strip or the others The tapes remain in a waiting position wound into a bundle.
- the method according to the invention also enables lower final thicknesses to be achieved, e.g. without additional energy expenditure. Furthermore, there is an improvement in the geometric Product tolerances (profile, thickness, flatness) in a simple manner and without great Additional effort possible.
- the temperature compensation also means that The increase in the rolling force when the strip ends are inserted into the roll stand is minimized and the Roller bearings less stressed.
- the band or bands it is expedient for the band or bands to form a bundle a heat compensation carried out, e.g. including the Band end or the band ends.
- the method according to the invention enables not only optimal temperature conditions adjust for rolling, but it can also be used for that To improve the material properties of the tape before or after a stitch acceptance, i.e. by a specific temperature effect, for example depending on the thickness and Quality of the rolled stock, physical properties of the strip or structure of the Band to improve, etc. in that for the tape or tapes in a bundle wound waiting position a heat treatment, in particular heating, is carried out, etc. including the tape end or the tape ends.
- a heat treatment in particular heating

- On one side 2 of the Reversing roll stand 1 are two winding devices designed as reel furnaces 3 and 3 ' arranged.
- 3 to 3 " can be arranged between the coiler furnaces instead of the single one Reversing roll stand 1 also a multiple stand, in which the belt 9 or 9 'at one Passes two or more stitch approvals.
- the reel ovens 3 to 3 " are equipped with drivable reel mandrels 5 and each with equipped with a heat-insulated jacket 6. If necessary, they have heating devices 7 to a certain temperature level in the interior 8, 8 'of each coiler 3 to 3 " hold.
- the reel furnaces 3 to 3 " are designed in such a way that the strip ends of the rolling strip 9, 9 'completely drawn into the interior 8 of the reel furnaces 3 to 3 " can be.
- the reel furnaces 3 to 3 " have corresponding devices on how drive rollers 10 that can grasp the tape end and from each Can pull out reel furnace 3 to 3 ", as well as so-called coil opener 11, that is Wedge-shaped, 12 adjustable devices on the wound coil - also Called collar opening swords - which allow the end of the band to be detached from collar 12 and lead out of the interior 8 of each reel furnace 3 to 3 "
- Bundle opener 11 on the bundle surface of a bundle 12 wound on a coiler mandrel 5 serve actuators not shown.
- a 3 to 3 "coiler can also be used with an insulated, possibly heatable Entry or exit zone may be provided, which is optionally pivotable to the Bring the belt and the entry and exit zones out of the roller table area.
- two strips 9, 9 ' can be rolled alternately become. While one strip 9 is being rolled, the other strip 9 'in the second is both on the side 2 of the reversing roll stand 1 adjacent coiler furnaces 3, 3 'in to a bundle 12 wound waiting position. While the band 9 'remains here until it is used for rolling, i.e. the other band 9 in two or more roll passes rolled, temperature compensation or heat treatment, possibly even be carried out under a protective gas atmosphere. Then when the second strip 9 'is rolled is, the first rolled strip 9 is in a waiting position wound into a bundle and can in turn be subjected to temperature compensation for subsequent rolling passes become.
- reel mandrels 5 arranged adjacent and surrounded by a common heat protection housing 6. 2
- the reel mandrels 5 are in a horizontally adjacent arrangement and according to FIG. 3 arranged in a vertically adjacent arrangement.
- a continuous caster 13 with a mold 14, a roller guide track 15 and one of these downstream separating device 16, a temperature compensation furnace 17th downstream to accommodate tapes separated from the strand.
- Strand 18 is like him emerges from the mold 14, not thin enough to be wound in the solidified state To be able to be, is in the continuous caster not shown Roughing mill provided for rolling a windable strand 18.
- winding devices 3 to 3 "'and a reversing roll stand 1 is arranged in between. According to that shown in Fig. 4 Exemplary embodiments are on each side 2 and 4 of the reversing roll stand 1, respectively two reel furnaces 3, 3 'and 3 ", 3"' are provided. It could also be more or just on one of the two sides 2 and 4 of the reversing roll stand 1 is a single coiler.
- the function is as follows: First, a band 9 'separated from the strand 18 is inserted into the Temperature compensation furnace 17 directly fed, etc. with a the Continuous casting speed significantly higher take-off speed. After one The band 9 'is temperature equalized according to the method according to the invention alternately rolled with a second strip 9 previously separated from the strand 18.
- the method according to the invention makes it possible - as shown in FIG To waive temperature compensation furnace 17, namely it can in the strand conveying direction
- First arranged reel furnace 3 take over this function without the inventive Reverse rolling process is disrupted.
- 2 and 4 of the Reversing roll stand each arranged at least two reel furnaces 3, 3 'and 3 ", 3"'.
- FIG. 6 shows a special design of a reel furnace 3 arranged first in the strand outlet direction, which has its own tape inlet opening 19 and its own tape outlet opening 20, similar to shown in Fig. 3.
- the coiler mandrel 21 (there are two coiler mandrels 21 here symmetrical provided to the axis of symmetry) of this reel furnace 3 is by means of an adjusting device in a Winding start position I at the tape inlet opening 19 for the purpose of detecting the beginning of the tape and in an unwinding position II in which a coil 12 wound on the coiler mandrel 21 against a pressure roller 22 which is fixedly arranged or to be pressed on the reel furnace 3 is pressed, movable, the pressure roller 22 in the unwinding direction Tape exit opening 20 is upstream.
