Description
Die Erfindung betrifft ein Verfahren zum Herstellen von gewalzten oder gegossenen Metallbändern, insbesondere Stahlbändern aus Edelstahl- und Titanlegierungen, mit einer entzunderten Oberfläche, wonach das betreffende Metallband geglüht, zum mechanischen Vorentzundern streckbiegegerichtet und zum chemischen und/oder elektrolytischen Nachentzundern gebeizt wird. - Im Rahmen der Erfindung meint gewalzte Metallbänder bzw. Stahlbänder sowohl warmgewalzte als auch kaltgewalzte Bänder.The invention relates to a method for producing rolled or cast metal strips, especially steel strips made of stainless steel and titanium alloys, with a descaled Surface, after which the metal strip in question is annealed, for mechanical pre-descaling and for chemical and / or electrolytic descaling is stained. - In the context of the invention means rolled metal strips or steel strips both hot rolled as well cold rolled strips.
Es ist ein derartiges Behandlungsverfahren bekannt, wonach das betreffende Metallband im Zuge der Herstellung einer entzunderten Bandoberfläche zunächst geglüht, dann zur mechanischen Vorentzunderung streckbiegegerichtet und anschließend gestrahlt und/oder gebürstet wird, um dann zum chemischen Nachentzundern gebeizt zu werden, so daß schließlich ein Metall- bzw. Stahlband mit einer sauberen Bandoberfläche zur Verfügung steht. Das Glühen dient im allgemeinen zur Beseitigung von Kaltverfestigungen. - Das Strahlen und/oder Bürsten der Metallbänder ist verhältnismäßig zeit- und in anlagentechnischer Hinsicht investitionsaufwendig. Die dafür erforderlichen Strahlanlagen und Bürstmaschinen verursachen erhebliche Instandhaltungs- und Betriebskosten. - Hier setzt die Erfindung ein.Such a treatment method is known, according to which the metal strip in question in the course of producing a descaled strip surface first annealed, then for mechanical Pre-descaling straightened and then is blasted and / or brushed, and then to chemical descaling to be pickled so that finally a metal or steel band with a clean one Belt surface is available.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Herstellen von gewalzten oder gegossenen Metallbändern, insbesondere Stahlbändern aus Edelstahl- und Titanlegierungen, der eingangs beschriebenen Ausführungsform zu schaffen, wonach die Entzunderung in kostenreduzierender Weise optimiert wird. Außerdem soll eine zur Durchführung dieses Verfahrens geeignete Bandlinie geschaffen werden.The invention has for its object a method for Manufacture of rolled or cast metal strips, especially steel strips made of stainless steel and titanium alloys, the embodiment described above create what the descaling in cost-reducing Way is optimized. In addition, one should be carried out suitable band line can be created using this method.
Diese Aufgabe löst die Erfindung bei einem gattungsgemäßen Verfahren dadurch, daß das Streckbiegerichten unmittelbar vor dem Glühen und das Beizen unmittelbar nach dem Glühen vorgenommen werden. Unmittelbar meint im Rahmen der Erfindung ohne Zwischenschaltung von weiteren Behandlungsmaßnahmen. - Überraschenderweise ist die mechanische Vorentzunderung signifikant besser, wenn das Streckbiegerichten vor dem Glühen stattfindet. Es hat sich herausgestellt, daß die Metallbänder und insbesondere Edelstahlbänder so gut vorentzundert werden, daß sie ohne Strahlen und/oder Bürsten mit maximaler Geschwindigkeit in der Bandlinie gefahren werden können und dennoch die Bandfläche nach dem Beizen einwandfrei sauber ist. Insoweit wird nach Lehre der Erfindung die Entzunderung optimiert, während der gesamte Entzunderungsprozeß in kostensparender Weise rationalisiert wird. Denn nach Lehre der Erfindung kann nunmehr auf das Strahlen und/oder Bürsten der Metall- bzw. Stahlbänder und folglich auch insoweit auf die sonst erforderlichen anlagentechnischen Einrichtungen in der Bandbehandlungslinie verzichtet werden. Daher ist die zur Durchführung des erfindungsgemäßen Verfahrens besonders geeignete Bandbehandlungslinie mit zumindest einem Abwickelhaspel, einer Streckbiegerichteinrichtung zum mechanischen Vorentzundern, einer Glühe, einer Beize zum chemischen und/oder elektrolytischen Nachentzundern und einem Aufwickelhaspel dadurch gekennzeichnet, daß die Streckbiegerichtvorrichtung in Bandlaufrichtung unmittelbar vor der Glühe und die Beize unmittelbar hinter der Glühe angeordnet ist. Unmittelbar meint in diesem Zusammenhang ohne Zwischenschaltung von anderen Bandbehandlungsaggregaten. Das schließt folglich nicht aus, daß in Bandlaufrichtung vor und/oder hinter der Streckbiegerichtvorrichtung ein Bandspeicher angeordnet sein kann. - Im Rahmen der Erfindung werden jedenfalls die Investitionskosten von neu zu installierenden Bandbehandlungslinien wegen der nicht länger erforderlichen Strahlanlagen und Bürstmaschinen erheblich reduziert. Das gilt insoweit auch für die Instandhaltungs- und Betriebskosten. Eine erfindungsgemäße Bandbehandlungslinie ohne Strahlanlage und Bürstmaschinen ist auch dann vorteilhaft, wenn außer warmgewalzten auch kaltgewalzte Bänder geglüht und gebeizt werden müssen. Denn üblicherweise muß bei der Umstellung der Bandbehandlungslinie von Warmband auf Kaltband die sonst erforderliche Strahlanlage gereinigt werden, damit kein Strahlgut die glatte Oberfläche der Kaltbänder beschädigen kann. Das gilt auch für verschiedene Rollen. Die damit verbundenen Produktionsausfallzeiten entfallen bei der erfindungsgemäßen Bandbehandlungslinie. - Sofern einlaufseitig Bandspeicher vorgesehen sind, kann ein Bandspeicher vor und/oder hinter der Streckbiegerichtvorrichtung angeordnet sein. Durch den Einsatz solcher Bandspeicher werden Stillstandsmarkierungen vermieden, die im Bereich der Streckbiegerollen auftreten können, wenn das betreffende Metallband im Einlaufbereich zum Zwecke des Bundwechsels oder Anschweißens eines nachfolgenden Metallbandes angehalten wird. Denn die Bandspeicher ermöglichen einen kontinuierlichen Banddurchlauf. Dabei kann der vor der Streckbiegerichtvorrichtung angeordnete Einlaufspeicher so klein gewählt werden, daß die Streckbiegerichtvorrichtung während des Bandstillstandes im Einlauf nur im Kriechbetrieb weiterläuft. Unter dieser Voraussetzung sind Bandlauf- und Markierungsprobleme vernachlässigbar.The invention solves this problem with a generic one Procedure in that the stretch bending straightening immediately before annealing and pickling immediately after annealing be made. Immediately means within the scope of the invention without the interposition of further treatment measures. - Surprisingly, the mechanical pre-descaling significantly better if the stretch bending judging before the glow takes place. It has been found that the metal straps and especially stainless steel straps so well be pre-descaled that they are without blasting and / or brushing Driven at maximum speed in the belt line can and still the strip surface after pickling is perfectly clean. In this respect, according to the teaching of Invention optimized descaling throughout Descaling process rationalized in a cost-saving manner becomes. Because according to the teaching of the invention can now on Blasting and / or brushing the metal or steel strips and consequently also to the extent necessary on the other technical equipment Facilities in the belt treatment line to be dispensed with. Therefore, the one for performing the invention Band treatment line particularly suitable for the process with at least one decoiler, one Stretch bending straightening device for mechanical pre-descaling, a glow, a chemical and / or electrolytic pickle Post-descaling and a take-up reel characterized in that the stretch bending straightening device in Direction of strip running immediately before the annealing and pickling is located immediately behind the glow. Right away means in this context without the interposition of others Belt processing units. So that concludes not from that in the tape running direction before and / or behind the Stretch bending straightening device arranged a tape store can be. - In any case, within the scope of the invention Investment costs of new belt treatment lines to be installed because of the blasting systems no longer required and brushing machines significantly reduced. That applies in this respect also for the maintenance and operating costs. A belt treatment line according to the invention without a blasting system and brushing machines is also advantageous when except hot-rolled and also cold-rolled strips annealed and pickled Need to become. Because usually when switching the strip treatment line from hot strip to cold strip the otherwise necessary blasting system is cleaned, thus no blasting material the smooth surface of the cold strips can damage. This also applies to different roles. The associated production downtimes are eliminated in the belt treatment line according to the invention. - Provided A tape store can be provided on the inlet side in front of and / or behind the stretch bending straightening device be arranged. By using such tape storage standstill marks are avoided in the area The stretch bending rolls can occur if the one in question Metal band in the infeed area for the purpose of changing the waistband or welding a subsequent metal strip is stopped. Because the tape storage allows you continuous belt pass. The can before Straightening straightening device arranged inlet storage so be chosen small that the stretch bending straightening device during the belt standstill in the inlet only in crawl mode continues. Under this condition, tape running and marking problems are negligible.
Im Rahmen der Erfindung läßt sich allerdings dann vor und/oder hinter der Glühe bzw. dem Glühofen eine Strahlmaschine und/oder Bürstmaschine anordnen, wenn besonders schwer entzunderbare Metallbänder nicht nur im Wege des Streckbiegerichtens, sondern eben auch im Wege des Strahlens und/oder Bürstens mechanisch vorentzundert werden müssen. Im übrigen kann der Beize ein Dressiergerüst und/oder eine Streckbiegerichtanlage nachgeordnet sein, um in Bezug auf Planheit, Oberflächenrauhigkeit und Glanz die jeweils verlangten Eigenschaften erreichen zu können. Das Dressiergerüst kann mit texturierten Walzen ausgerüstet sein, wenn gemusterte bzw. definierte Bandoberflächen erwünscht sind. Im übrigen besteht die Möglichkeit, das betreffende Metallband nach dem Entzundern im Wege des Streckbiegerichtens oder vor dem Aufwickeln zu spalten und/oder zu besäumen.However, within the scope of the invention and / or a blasting machine behind the glow or the annealing furnace and / or arrange brushing machine if special metal tapes difficult to descale not only in the way of Stretch bending, but also by blasting and / or brushing must be mechanically pre-descaled. Otherwise, the stain can be a skin pass mill and / or a stretch bending straightener may be subordinate to in relation for flatness, surface roughness and gloss each to be able to achieve the required properties. The skin pass mill can be equipped with textured rollers if patterned or defined belt surfaces are desired. Otherwise there is the possibility of the metal strip in question after descaling by stretch bending straightening or to split and / or trim before winding.
