Description
Die Erfindung bezieht sich auf eine Anordnung und auf ein Verfahren zum Erzeugen von Stahlband gemäß den Oberbegriffen der Ansprüche 1 und 8.The invention relates to an arrangement and a method for producing of steel strip according to the preambles of claims 1 and 8.
Aus der DE 195 05 324 C2 ist ein Verfahren zum Herstellen von kaltgewalzten Stahlbändern in einer kontinuierlichen Bandbehandlungslinie und folglich ohne Zwi schenlagerungen von Coils innerhalb dieser Bandbehandlungslinie bekannt, wonach Warmband in einem Durchlauf zum gewünschten kaltgewalzten Endprodukt verar beitet wird.DE 195 05 324 C2 describes a method for producing cold-rolled Steel strips in a continuous strip treatment line and consequently without intermediate known coils within this belt treatment line, after which Process hot strip in one pass to the desired cold-rolled end product is being processed.
Dieses bekannte Verfahren integriert die Kaltverformung in die Bandbehandlungsli nie und gewährleistet die Herstellung von Stahlbändern, insbesondere Edelstahl bändern, mit in Bezug auf Planheit, Sauberkeit, Oberflächenrauhigkeit und Glanz verlangten Eigenschaften in einem kontinuierlichen Bandbehandlungsprozeß, wobei jedoch als Ausgangsmaterial Warmband dient, das in einem hiervon getrennten Pro zeß produziert und in Coils zwischengelagert wurde.This known method integrates cold forming into the strip treatment line never and ensures the production of steel strips, especially stainless steel tapes with flatness, cleanliness, surface roughness and gloss required properties in a continuous belt treatment process, whereby however, hot strip serves as the starting material, which is produced in a separate Pro was produced and temporarily stored in coils.
Der Erfindung liegt die Aufgabe zugrunde, eine Anordnung und ein Verfahren zum Erzeugen von Stahlband der eingangs genannten Art anzugeben, bei der bzw. bei dem die konventionelle Produktionsweise Bandgießen oder Dünnbrammengießen mit Warmwalzen - Kaltwalzen - Veredeln in Bezug auf Wirtschaftlichkeit und Materi aldurchsatz optimiert und Stahlband von gewünschter, gegebenenfalls unterschiedli cher Qualität produzierbar ist.The invention has for its object an arrangement and a method for Production of steel strip of the type mentioned at the point of which the conventional production method strip casting or thin slab casting with hot rolling - cold rolling - finishing in terms of economy and material Optimized throughput and steel strip of the desired, possibly different quality is producible.
Diese Aufgabe wird hinsichtlich der Anordnung in Verbindung mit den Merkmalen des Oberbegriffes erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 an gegebenen Merkmale gelöst.This task is related to the arrangement in connection with the features of the preamble according to the invention in the characterizing part of claim 1 given characteristics solved.
Diese Aufgabe wird hinsichtlich des Verfahrens in Verbindung mit den Merkmalen des Oberbegriffes erfindungsgemäß durch die im Kennzeichen des Anspruchs 8 an gegebenen Merkmale gelöst.This task is related to the method in connection with the features of the preamble according to the invention in the characterizing part of claim 8 given characteristics solved.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß die Er zeugung des Warmbandes und der sich anschließende Bandbehandlungsprozeß im Sinne einer Gesamtintegration zu einem einzigen Prozeß in einer einzigen Anlage zusammengefaßt sind. Alle bekannten Verfahren und Anlagen mit dem Ziel, den Produktionsprozeß für Stahlband zu verbessern, gehen von einer Trennung des Pro zeßablaufes und der Anlage nach der Erzeugung des Warmbandes - sei es durch Bandgießen oder Dünnbrammengießen mit Warmwalzen - aus. Die erfindungsge mäß vorgeschlagene Gesamtintegration hat Kostenvorteile, denn es werden bei spielsweise die Aufhaspelgruppe einer konventionellen Warmbandanlage, die Mate rialversorgung einer konventionellen Bandbehandlungsanlage mit einer Abhaspel gruppe und der notwendige Transport der Coils von der einen zur anderen Anlage eingespart. Es wird ein kontinuierlicher Gesamtprozeß realisiert, der nur in relativ großen Zeitintervallen zu Wartungszwecken und zum Austausch von Verschleißtei len unterbrochen werden muß.The advantages that can be achieved with the invention are, in particular, that the Er Production of the hot strip and the subsequent strip treatment process in In terms of total integration into a single process in a single system are summarized. All known processes and plants with the aim of To improve production process for steel strip, go from a separation of the pro and the system after the production of the hot strip - be it through Strip casting or thin slab casting with hot rolling - off. The fiction According to the proposed overall integration has cost advantages, because for example, the rewinder group of a conventional hot strip system, the Mate rial supply of a conventional strip treatment plant with one decoiler group and the necessary transport of the coils from one system to the other saved. A continuous overall process is realized, which is only relative large time intervals for maintenance purposes and to replace wear parts len must be interrupted.
Ein weiterer Vorteil der Gesamtintegration ergibt sich in Bezug auf die Bandführung im Auslauf einer konventionellen Warmbandstraße und beim Einfädeln in eine kon ventionelle Bandbehandlungslinie. Bei der Gesamtintegration entfallen die kritischen Phasen während des Ein- und Ausfädeln des Stahlbandes der einzelnen Coils. Eine vergleichbar kritische Phase entsteht bei der Gesamtintegration nur beim Anfahren der Gesamtanlage. Zur Erhöhung der Sicherheit kann das Anfahren auch mit verrin gerter Geschwindigkeit erfolgen, wobei die Gießgeschwindigkeit der Bandgießma schine entsprechend kontinuierlich verändert wird. Another advantage of the overall integration is the tape guidance in the outlet of a conventional hot strip mill and when threading into a con conventional belt treatment line. The critical ones are eliminated in the overall integration Phases during the threading and unthreading of the steel strip of the individual coils. A a comparable critical phase arises with the overall integration only when starting the entire system. To increase safety, the start can also be reduced gerter speed, the casting speed of the Bandgießma machine is continuously changed accordingly.
Vorteilhaft wird das Warmwalzen von Stahlbändern im sehr kleinen Dickenbereich von 1 mm realisierbar, da infolge der Integration der nachfolgenden Bandbehand lungsprozesse die problematische Bandführung eines solch dünnen Bandes ent scheidend erleichtert wird. Die Temperaturführung beim und nach dem Warmwalzen spielen neben der Stahlzusammensetzung eine entscheidende Rolle für die späteren Materialeigenschaften des Stahlbandes. Auch in diesem Punkt ist das erfindungs gemäße Verfahren vorteilhaft, da diesbezüglich gewünschte Temperaturführungen wahlweise durch Heizen und/oder Kühlen realisiert werden können.The hot rolling of steel strips in the very small thickness range is advantageous of 1 mm can be realized as a result of the integration of the following belt treatment development processes the problematic tape guidance of such a thin tape is greatly relieved. The temperature control during and after hot rolling In addition to the steel composition, they play a decisive role for the later ones Material properties of the steel strip. This is also fiction in this point appropriate process advantageous because of the desired temperature control in this regard can optionally be realized by heating and / or cooling.
Die Erfindung wird nachstehend anhand der in der Zeichnung dargestellten Ausfüh rungsbeispiele erläutert. Es zeigen:The invention is described below with reference to the embodiment shown in the drawing Examples explained. Show it:
Fig. 1 eine erste Ausführungsform einer Anlage zum Erzeugen von Stahlband, Fig. 1 shows a first embodiment of a plant for producing steel strip,
Fig. 2 eine zweite Ausführungsform einer Anlage zum Erzeugen von Stahlband, Fig. 2 shows a second embodiment of a plant for producing steel strip,
Fig. 3 eine dritte Ausführungsform einer Anlage zum Erzeugen von Stahlband. Fig. 3 shows a third embodiment of a plant for producing steel strip.
In Fig. 1 ist eine erste Ausführungsform einer Anlage zum Erzeugen von Stahlband dargestellt. Diese Ausführungsform ist für Anlagengeschwindigkeiten bis ungefähr 100 m/min geeignet. Eine Bandgießmaschine 1a erzeugt Gießband von gewünschter Dicke (beispielsweise im Bereich von 1 bis 8 mm), das über einen Rollgang mit einer Kühlstrecke 2 einem Bandspeicher 3 zugeführt wird. Die Kapazität des Bandspei chers 3 ist derart bemessen, daß bei unveränderter Gießgeschwindigkeit zumindest diejenige Menge Warmband B gespeichert werden kann, die während des Zusam menschweißens (siehe Schweißmaschine 6) des Endes eines "alten", bei Produkti onsende in der Schweißmaschine positionierten Warmbandes mit dem Anfang eines "neuen", bei Produktionsbeginn hergestellten Warmbandes, von der Bandgießma schine produziert wird.In Fig. 1 a first embodiment of a system is shown for producing steel strip. This embodiment is suitable for system speeds of up to approximately 100 m / min. A strip casting machine 1 a produces casting strip of the desired thickness (for example in the range from 1 to 8 mm), which is fed to a strip store 3 via a roller table with a cooling section 2 . The capacity of the Bandspei chers 3 is such that at unchanged casting speed at least that amount of hot strip B can be stored, which during welding together (see welding machine 6 ) of the end of an "old" hot strip positioned at the end of production in the welding machine with the Beginning of a "new" hot strip produced at the start of production, which is produced by the strip casting machine.
Das Warmband B kann nach dem Bandspeicher 3 mit Hilfe einer Schere 4 geschopft oder bei Bedarf geteilt werden. Eine nach der Schere 4 angeordnete Aufhaspel 5 ermöglicht die bedarfsweise Aufwicklung von Warmband, welches den nach der Schere 4 vorgesehenen Prozeßablauf nicht durchlaufen soll. Des weiteren dient die Aufhaspel 5 dem Zweck, bei einer Störung in dem der Schere 4 nachgeschalteten Anlagenteil das produzierte Warmband aus dem vorgeschalteten Anlagenteil aufzu nehmen.The hot strip B can be scooped after the strip storage 3 with the aid of scissors 4 or divided if necessary. A reel 5 arranged after the scissors 4 enables the hot strip to be wound up if necessary, which should not go through the process sequence provided for by the scissors 4 . Furthermore, the reel 5 serves the purpose of taking up the hot strip produced from the upstream system part in the event of a fault in the system part connected downstream of the scissors 4 .
Im normalen Betrieb durchläuft das Warmband nach der Schere 4 eine Schweißma schine 6, in der bedarfsweise ein "neues" Warmband nach dem Schopfen mit dem "alten" Band zusammengeschweißt werden kann. Der Schweißmaschine 6 nachge ordnet sind Bandbehandlungseinrichtungen 7, die ein Streckrichten und/oder Reini gen und/oder Beizen und/oder Glühen und/oder Reduzieren durch Kaltverformen und/oder Beschichten und/oder Dressieren und/oder Besäumen des Warmbandes B durchführen. Eine am Ende der Anlage angeordnete Aufhaspel 8 wickelt das fertig gestellte Stahlband auf.In normal operation, the hot strip after the scissors 4 passes through a welding machine 6 , in which, if necessary, a "new" hot strip can be welded together with the "old" strip after cropping. The welding machine 6 is arranged according to strip treatment devices 7 , which perform stretch straightening and / or cleaning and / or pickling and / or annealing and / or reducing by cold working and / or coating and / or skin passaging and / or trimming the hot strip B. A reel 8 arranged at the end of the system winds up the finished steel strip.
In Fig. 2 ist eine zweite Ausführungsform einer Anlage zum Erzeugen von Stahlband dargestellt, bei der die Gesamtintegration Warmbanderzeugung - Bandbehandlung direkt ohne Bandspeicher und Schweißmaschine erfolgt. Diese Ausführungsform ist für Anlagengeschwindigkeiten über 100 m/min geeignet. Eine Dünnbrammengießan lage 1b erzeugt Gießband von gewünschter Dicke, das durch einen Ausgleichsofen 9 zu einer Warmverformungsvorrichtung, d. h. Warmwalzgerüsten 10 gelangt, in de nen das Warmband entsprechend den Erfordernissen reduziert wird (beispielsweise auf Warmbanddicken unter 1 mm). Beim und nach dem Warmwalzen werden die Materialeigenschaften im gewünschten Sinn beeinflußt, beispielsweise durch Walzen im Ferritbereich derart, daß die nachfolgenden Prozesse, wie beispielsweise die Kaltverformung, mit reduziertem Aufwand durchgeführt werden können. FIG. 2 shows a second embodiment of a system for producing steel strip, in which the overall integration of hot strip production - strip treatment takes place directly without a strip store and welding machine. This embodiment is suitable for system speeds above 100 m / min. A thin slab casting plant 1 b produces casting strip of the desired thickness, which passes through a compensating furnace 9 to a hot-forming device, ie hot rolling stands 10 , in which the hot strip is reduced according to requirements (for example to hot strip thicknesses below 1 mm). During and after hot rolling, the material properties are influenced in the desired sense, for example by rolling in the ferrite area in such a way that the subsequent processes, such as cold forming, can be carried out with reduced effort.
Das Warmband B gelangt nach dem Walzen zur gezielten Temperaturführung und damit zur Einstellung gewünschter Materialeigenschaften in eine Einrichtung 11 zur Temperaturführung durch Heizen und/oder Kühlen während eines vorgegebenen Temperatur/Zeit-Zyklusses. Mit der optimalen Bandtemperatur läuft das Stahlband anschließend durch eine Streckrichteinheit 13 in eine Beizeinrichtung 14.After rolling, the hot strip B arrives for targeted temperature control and thus for setting desired material properties in a device 11 for temperature control by heating and / or cooling during a predetermined temperature / time cycle. At the optimum strip temperature, the steel strip then runs through a straightening unit 13 into a pickling device 14 .
Der Beizeinrichtung 14 nachgeordnet sind Bandbehandlungseinrichtungen 15, die ein Reduzieren (Kaltverformen) und/oder Dressieren sowie Besäumen durchführen. Es schließt sich eine Schere 16 an. Am Ende der Anlage angeordnete Aufhaspeln 17, 18 wickeln abwechselnd das fertiggestellte Stahlband auf. Downstream of the pickling device 14 are strip treatment devices 15 which carry out a reduction (cold forming) and / or skin passaging and trimming. A pair of scissors 16 follows. Reels 17 , 18 arranged at the end of the system alternately wind up the finished steel strip.
In Fig. 3 ist eine dritte Ausführungsform einer Anlage zum Erzeugen von Stahlband dargestellt. Diese Anlage stellt im wesentlichen eine Kombination der vorstehend beschriebenen Ausführungsformen nach den Fig. 1 und 2 dar. In ihrem ersten Ab schnitt entspricht die dritte Ausführungsform der vorstehend beschriebenen zweiten Ausführungsform mit Bandgießmaschine 1b, Ausgleichsofen 9, Warmwalzgerüsten 10 und Einrichtung 11 zur Temperaturführung. In ihrem zweiten Abschnitt entspricht die dritte Ausführungsform der vorstehend beschriebenen ersten Ausführungsform, wonach sich nach dem Bandspeicher 3, Schere 4, bedarfsweise Aufhaspel 5, Schweißmaschine 6 und Bandbehandlungseinrichtungen 7 anschließen, welche ein Streckrichten und/oder Reinigen und/oder Beizen und/oder Glühen und/oder Redu zieren durch Kaltverformen und/oder Beschichten und/oder Dressieren und/oder Be säumen des Stahlbandes durchführen. Es folgt eine Schere 16. Am Ende der Anlage angeordnete Aufhaspeln 17, 18 wickeln abwechselnd das fertiggestellte Stahlband auf.In Fig. 3 shows a third embodiment of a plant is shown for producing steel strip. This system is essentially a combination of the above-described embodiments according to FIGS. 1 and 2. In its first Ab cut the third embodiment of the second embodiment described above with belt casting machine 1 b, soaking furnace 9, hot-rolling stands 10 and device 11 corresponds to the temperature control. In its second section, the third embodiment corresponds to the first embodiment described above, according to which, after the strip store 3 , scissors 4 , if necessary, reel 5 , welding machine 6 and strip treatment devices 7 follow, which straighten and / or clean and / or pickle and / or anneal and / or Reduce by cold working and / or coating and / or skin pass and / or Be hemming the steel strip. A pair of scissors 16 follows. Reels 17 , 18 arranged at the end of the system alternately wind up the finished steel strip.
Der Bandspeicher 3 ist insbesondere dann vorteilhaft, wenn die nachgeschaltete Bandbehandlungseinrichtung 7 ein Einfädeln unter Betriebsbedingungen nicht er laubt (beispielsweise bei großen Vertikalöfen). Bei einer solchen Anlage muß das Anfahren - je nach Höhe der optimalen Prozeßgeschwindigkeit - mit einer reduzier ten Geschwindigkeit erfolgen, um sicherzustellen, daß der Einfädelvorgang Dünn brammengießanlage 1b - Warmwalzgerüste 10 - Bandspeicher 3 - Schweißmaschi ne 6 störungsfrei verläuft. Dies bedeutet zunächst eine reduzierte Gießgeschwindig keit, die dann nach dem Zusammenschweißen von "altem" und "neuem" Band wäh rend des kontinuierlichen Betriebes zusammen mit der Gesamtanlage auf die ge wünschte Arbeitsgeschwindigkeit erhöht wird.The belt store 3 is particularly advantageous when the downstream belt treatment device 7 does not permit threading under operating conditions (for example in the case of large vertical furnaces). In such a system, the start-up - depending on the level of the optimal process speed - must be carried out at a reduced speed to ensure that the threading process is thin slab caster 1 b - hot rolling mill 10 - strip storage 3 - welding machine 6 runs smoothly. This initially means a reduced casting speed, which is then increased after the welding of the "old" and "new" strip during continuous operation together with the entire system to the desired working speed.
Alternativ kann die Schweißmaschine mit vorgeordneter Schere vor den Warmwalz gerüsten 10 angeordnet sein, um das Zusammenschweißen der Bänder bei Produk tionsbeginn zu ermöglichen.Alternatively, the welding machine can be arranged with upstream scissors in front of the hot rolling stands 10 to enable the strips to be welded together at the start of production.
