Definitions
- the invention relates to a process for the continuous production of a metallic, preferably cold-rolled strip, in particular a stainless steel strip, the strip to be produced being passed in a conveying direction through a device in which the strip is subjected to a rolling process, heating and chemical treatment. Furthermore, the invention relates to a device, in particular for performing the method.
- a metal strip passes through a production device in which various processes are carried out on the strip.
- the strip is reduced in thickness in a rolling process. It can also be followed by heat treatment, which gives the strip special material properties.
- the strip must have a scale-free surface, which is why it passes a pickling line in which the scale is removed by means of a chemical treatment.
- the hot-rolled steel strip For further processing - e.g. B. by cold rolling, for a metallic coating or direct processing into an end product - the hot-rolled steel strip must have a scale-free surface. Therefore, the scale created during hot rolling and during the subsequent cooling must be removed completely. This is usually done by a pickling process, with the scale consisting of the various iron oxides (FeO, Fe 3 O 4 , Fe 2 O 3 ) or, in the case of stainless steels, also of chromium-rich iron oxides, depending on the steel quality, using various acids (e.g. hydrochloric acid, sulfuric acid) , Nitric acid or mixed acid) is dissolved at elevated temperatures by chemical reaction with the acid.
- various acids e.g. hydrochloric acid, sulfuric acid
- Nitric acid Nitric acid
- a method or a device of the generic type is known from DE 100 22 045 C1. It is disclosed there that a strip is guided through a pickling device, a rolling unit being arranged in front of and behind the pickling device. In the conveying direction of the strip behind the second rolling unit, the strip passes through an annealing furnace and then a pickling tank in which the scale is removed from the surface of the strip. Before winding the finished strip to this extent, it can still be processed in a skin pass mill.
- WO 00/37189 and WO 00/37190 disclose a device for producing a metal strip, in which the strip is first reduced in thickness in a multi-stand rolling mill. The strip then goes into an annealing furnace; in the further course the strip is led through a pickling device. Before the strip is wound up, a rolling operation can also follow here, but this only makes a slight reduction in thickness on the strip.
- US 2001/0037667 A1 discloses a similar device for producing a metal strip. However, there is no heating of the belt here. The strip is only passed through a rolling mill in a pickling line after descaling.
- the equipment downstream of the rolling mill and here in particular the annealing furnace and the pickling line, is adapted in its dimensions to the strip thickness typically reduced by 30 to 40% by the rolling process Need to become; As the strip is already thinner but longer, the annealing furnace and pickling line must also be designed to be long enough, which leads to high system costs.
- the invention is therefore based on the object of creating a method and an associated device of the type mentioned at the outset with which it is possible to avoid the disadvantages mentioned, which in particular means greater productivity and economy in the production of a Tape to be achieved; the surface quality of the finished strip is also to be improved.
- this object is achieved in that the rolling process is carried out only after the strip has been heated and after the chemical treatment.
- the heating of the strip, the chemical treatment of the strip and the rolling process are preferably carried out in this order.
- the rolling process is preferably a tandem rolling process.
- the rolling process here means that the thickness of the strip is reduced significantly, preferably by at least 20%.
- the chemical treatment of the strip is preferably a pickling process.
- the inventive device for the continuous production of a metallic, cold-rolled strip has a device for heating, i. H. in particular for annealing the strip, a device for chemically treating the strip and a device for rolling the strip.
- the device for rolling the strip in the conveying direction is arranged behind the device for heating the strip and the device for chemically treating the strip, the device for rolling the strip having at least one tandem rolling train.
- This consists of several rolling stands, which can be designed as a 6-high rolling mill or as a Z-high rolling mill. Apart from this rolling device, no further device is required to reduce the thickness of the strip.
- a stretch-leveling unit can also be arranged between the device for heating the strip (annealing furnace) and the device for chemical treatment of the strip (pickling line). Furthermore, a metal grain blasting unit can be arranged between the annealing furnace and the pickling line. A trimming unit can also be arranged in the conveying direction behind the device for chemical treatment of the tape in order to cut the tape laterally.
- the device has at least one, preferably three, belt stores.
- the manufacturing device explained can also be operated as a combined hot and cold strip annealing and pickling line with an integrated rolling mill (tandem mill).
- a degreasing device can additionally be arranged in the conveying direction in front of the device for heating the belt, in particular in front of the infeed belt store.
- FIG. 1 An embodiment of the invention is shown.
- the single figure shows schematically a device for producing a stainless steel strip.
- the figure shows a device 2 on which a metal strip 1 (metal strand) is processed.
- the belt 1 is in the conveying direction R - d. H. in the figure from left to right - guided by the device 2, a continuous passage of the belt 1 (passage with a largely constant belt speed) being sought.
- the belt 1 is fed to the device 2 in an inlet section 13, not shown in detail.
- the tape 1 is unwound from an unwinding unit, not shown, and passed into the device 2.
- a degreasing device 12 follows in the conveying direction R, in which the belt surface is cleaned.
- the strip 1 then arrives in a strip store 9 (inlet store) which is positioned below a device 3 for heating the strip 1 (annealing furnace). It can be achieved via the tape store 9 that Continuous running of the belt is achieved even with minor external disturbances in the belt feed.
- the strip 1 is subjected to a heat treatment in the annealing furnace 3. Then there is a stretch leveling unit 6, in which the strip 1 is smoothed. A metal grain blasting unit 7 is arranged downstream of the stretch-leveling unit 6.
- a device 4 for the chemical treatment of the strip 1 is arranged, namely a pickling line, in which the strip 1 is guided through pools which are filled with acid.
- a strip store 11 (intermediate store) is arranged below the pickling line 4. From this the tape 1 runs into a trimming unit 8 in which the sides of the tape 1 are cut. The strip 1 passes from the trimming unit 8 via a further strip store 10 (outlet store) to the device 5 for rolling the strip 1.
- This device 5 is designed as a tandem rolling mill. There are three rolling stands 5a, 5b and 5c arranged one behind the other, in which the strip 1 is rolled and its thickness is thereby reduced.
- An outlet section 14 is arranged behind the tandem rolling mill 5 and has a winding unit (not shown) with which the finished strip 1 can be wound up.
- the tandem rolling mill 5 has three roll stands 5a, 5b and 5c, which can be designed in the form of a multi-roll cold rolling mill, a 6-high rolling mill or a Z-high rolling mill.
- the fact that the thickness of the strip 1 is only reduced in the only device 5 for rolling the strip 1 at the end of the device 2 shows the strip 1 in front of the tandem mill 5 a relatively large thickness, namely the thickness with which the strip 1 enters the device 2.
- the consequence of this is that the overall length of both the annealing furnace 3 and the pickling line 4 can be kept relatively short.
- Both the annealing furnace 3 and the pickling line 4 can thus be designed for the original thickness of the strip 1 with which the strip 1 enters the device 2.
- the thickness can be reduced without prior annealing, which leads to a smaller maximum thickness reduction of a maximum of 30 to 40%.
- the maximum thickness reduction of the strip 1 per pass through the device 2 depends only on the materials and the performance of the tandem rolling mill 5; no consideration has to be given to the unannealed strip.
- a roll stand of the tandem rolling mill 5 can be designed such that the strip 1 can be treated during a final annealing.
- the descaled and preferably already trimmed strip - following the device 2 - can run continuously into a downstream device (hot-dip galvanizing system, etc.) without intermediate storage and with uniform strip tension.
- the finished strip can be alternately wound up with two reels behind the downstream device and divided with scissors. LIST OF REFERENCE NUMBERS
