Abstract
Description
Die Erfindung betrifft ein Feinstahlwalzwerk, insbesondere Drahtwalzwerk zur Optimierung von Produktqualität und/oder Leistung der Fertigstraße.The invention relates to a fine steel rolling mill, in particular wire rolling mill for optimizing product quality and / or performance of the finishing train.
Bei älteren Feinstahlwalzwerken, insbesondere Drahtwalzwerken, besteht fallweise ein Bedarf zur Modernisierung und/oder Leistungssteigerung durch Um- und/oder Ausbau der vorhandenen Fertigstraße. Insbesondere trifft dies auf mit älteren Walzgerüsten ausgestattete Fertigstraßen zu, welche mit gesteigerten Anforderungen an Qualität und/oder Produktivität moderner Anlagen nicht mehr Schritt halten können und insbesondere dann, wenn zusätzlich zum vorhandenen Walzprogramm eine Aufstockung bezüglich Menge und/oder Qualität aus wirtschaftlicher Sicht wünschenswert erscheint und die vorhandene Walzanlage hierfür nicht ausreicht. Dabei wäre es aber aus wirtschaftlicher Sicht unvorteilhaft, die vorhandene Fertigstraße insgesamt durch eine neue Anlage zu ersetzen, weil die hierbei anfallenden Kosten nicht in ökonomischem Gleichgewicht zu dem zu erwartenden Produktionsgewinn stehen.In the case of older fine steel rolling mills, in particular wire rolling mills, there is occasionally a need to modernize and / or increase performance by converting and / or expanding the existing finishing train. In particular, this applies to finishing lines equipped with older rolling stands, which can no longer keep up with the increased demands on the quality and / or productivity of modern systems, and especially when, in addition to the existing rolling program, an increase in quantity and / or quality appears to be economically desirable and the existing rolling mill is not sufficient for this. From an economic point of view, however, it would be disadvantageous to replace the existing finishing train with a new system because the costs incurred are not in economic balance with the expected production profit.
Der Erfindung liegt die Aufgabe zugrunde, ein Feinstahlwalzwerk bzw. ein Drahtwalzwerk zur Optimierung von Produktqualität und/oder Leistung der Fertigstraße anzugeben, durch welches mit möglichst geringem Aufwand an Kosten sowie mit möglichst sparsamem Platzbedarf und ohne nennenswerten umbaubedingten Produktionsausfall eine Steigerung von Produktqualität und/oder Leistung der Fertigstraße möglich und/oder eine Erweiterung des Produktionsprogramms erreichbar ist.The invention is based on the object of specifying a fine steel rolling mill or a wire rolling mill for optimizing product quality and / or performance of the finishing train, through which an increase in product quality and / or performance of the finishing train is possible and / or an expansion of the production program can be achieved with the least possible effort in terms of costs and with the most economical space requirements and without any notable conversion-related loss of production.
Zur Lösung der Aufgabe wird bei einem Walzwerk der im Oberbegriff von Anspruch 1 genannten Art mit der Erfindung vorgeschlagen, daß der Fertigstraße wenigstens ein zweigerüstiger Standard-Vorblock vor- und/oder nachgeordnet ist.To achieve the object, it is proposed in a rolling mill of the type mentioned in the preamble of claim 1 with the invention that the finishing train is upstream and / or downstream of at least one two-stand standard bloom.
Bei dem als Standard-Vorblock bezeichneten zweigerüstigen Anlagenteil handelt es sich um ein ausgereiftes und bewährtes Grundelement in Form eines Bausteins, wobei dieses Grundelement beispielsweise durch Aneinanderreihen mehrerer derartiger Bausteine zu einer mehrgerüstigen Einheit zusammengefügt und ohne Adaptionsprobleme zu einer mit beliebiger Anzahl von Gerüsten ausgebildeten Draht-Fertigstraße ausgebaut werden kann. Beispielsweise kann ein einzelner Grundbaustein zur Nachtolerierung einer Drahtabmessung der Fertigstraße nachgeordnet sein. Auch kann bei älteren Gerüsten einer Fertigstraße, wenn solche Gerüste z. B. bei Reparaturen zeitweilig ausfallen, die dann fehlende Walzkapazität durch Vor- oder Nachrüsten eines oder mehrerer Standard-Vorblöcke kompensiert werden. Es ergeben sich somit durch variablen Einsatz von zweigerüstigen Standard-Vorblöcken in einer Anordnung nach dem Baukastenprinzip eine Anzahl kostengünstiger und schnell durchführbarer Möglichkeiten zum Leistungserhalt, zur Leistungssteigerung und/oder zur Qualitätssteigerung einer vorhandenen Fertigstraße.The two-stand system part referred to as the standard bloom block is a mature and proven basic element in the form of a building block, this basic element being joined together, for example by stringing together several such building blocks, to form a multi-stand unit and without adaptation problems to form a wire formed with any number of stands. Finishing line can be expanded. For example, a single basic module for post-tolerance of a wire dimension can be arranged downstream of the finishing train. With older scaffolding a finishing train, if such scaffolding z. B. temporarily fail during repairs, the missing rolling capacity can then be compensated for by pre- or retrofitting one or more standard blooms. The variable use of two-stand standard blooms in an arrangement based on the modular principle results in a number of inexpensive and quickly implementable options for maintaining performance, increasing performance and / or increasing the quality of an existing finishing train.
Nach einer Ausgestaltung der Erfindung können dabei zweigerüstige Standard-Vorblöcke zu vier-, sechs-, acht- oder zehn-gerüstigen Vorblock-Einheiten zusammengeschaltet und der Fertigstraße vor- und/oder nachgeordnet sein.According to one embodiment of the invention, two-stand standard blooms can be interconnected to four, six, eight or ten-stand bloom units and can be arranged upstream and / or downstream of the finishing train.
Eine weitere Ausgestaltung sieht vor, daß beispielsweise zwecks Reparatur wirkungslos gemachte Gerüste der Fertigstraße durch wenigstens einen Standard-Vorblock ersetzt sind.Another embodiment provides that, for example, scaffolds of the finishing train that have been rendered ineffective for repair are replaced by at least one standard bloom block.
Nach einer anderen Ausgestaltung der Erfindung ist vorgesehen, daß eine Fertigstraße durch eine Anzahl zu einem Fertigblock zusammengefaßter, jeweils zweigerüstiger Standard-Vorblöcke überbrückt ist. Hierbei kann beispielsweise die Maßnahme getroffen sein, daß in dem die Fertigstraße überbrückenden Anlagenteil eine andere Drahtabmessung gewalzt wird, als in dem Anlagenteil mit der vorhandenen Fertigstraße.According to another embodiment of the invention, it is provided that a finishing train is bridged by a number of standard pre-blocks, each of which has two stands and is combined to form a finishing block. In this case, for example, the measure can be taken that a different wire dimension is rolled in the plant part bridging the finishing train than in the plant part with the existing finishing train.
Ein nach der Erfindung ausgebildetes Feinstahl- bzw. Drahtwalzwerk weist somit wenigstens einen der Fertigstraße vor- und/oder nachgeordneten Standard-Vorblock und/oder fallweise eine Überbrückung durch Standard-Vorblöcke auf. Ein solcher Umbau- bzw. Ausbausatz kann in überraschend unkomplizierter Weise nach dem Baukastenprinzip der Fertigstraße angegliedert sein.A fine steel or wire rolling mill designed according to the invention thus has at least one standard bloom block upstream and / or downstream of the finishing train and / or in some cases a bridging by standard bloom blocks. Such a conversion or expansion kit can be incorporated in a surprisingly uncomplicated manner according to the modular principle of the finishing train.

Figur 1 zeigt einen einzelnen zweigerüstigen Vorblock (10) als beliebig kombinierbaren Baustein zum Vor- oder Nachordnen an eine vorhandene Fertigstraße (1) (Fig. 5).FIG. 1 shows a single two-stand pre-block (10) as an arbitrarily combinable building block for upstream or downstream of an existing finishing train (1) (FIG. 5).
Figur 2 zeigt eine viergerüstige Einheit (11), zusammengesetzt aus zwei zweigerüstigen Standard-Vorblöcken (10). Diese sind durch ein gemeinsames Antriebsaggregat (20) miteinander verbunden.Figure 2 shows a four-stand unit (11), composed of two two-stand standard blocks (10). These are connected to one another by a common drive unit (20).
Eine achtgerüstige Draht-Vorblockeinheit (13) zeigt Figur 3. Diese setzt sich aus vier baukastenmäßig aneinandergereihten Standard-Vorblöcken (10) mit einem gemeinsamen Antrieb (20) zusammen.An eight-stand wire pre-block unit (13) is shown in FIG. 3. This is made up of four modular units Standard blooms (10) together with a common drive (20).
Die Figuren 2 und 3 zeigen insgesamt unkomplizierte Kombinationsmöglichkeiten mehrgerüstiger Einheiten unter Verwendung von Standard-Vorblöcken (10) als Grundbausteinen. Dabei ist die Anzahl solcher Grundbausteine (10) beliebig.Figures 2 and 3 show a total of uncomplicated combinations of multi-unit units using standard blocks (10) as basic building blocks. The number of such basic building blocks (10) is arbitrary.
Durch "Aneinanderketten" von Vorblöcken zu Fertigblöcken können auf diese Weise vier-, sechs-, acht- und fallweise zehn-gerüstige Anlagenteile zusammengestellt und vorhandene Anlagenteile damit ergänzt bzw. weiter ausgebaut werden.By "chaining together" from pre-blocks to finished blocks, four, six, eight and occasionally ten-stand system parts can be put together and existing system parts can be supplemented or expanded.
Figur 4 zeigt im Gegensatz zum baukastenmäßigen "Aneinanderketten" von einzelnen Standard-Vorblöcken die Konstruktion eines herkömmlichen Fertigblockes in einer Ausführung nach dem Stand der Technik. Es ist ersichtlich, daß ein schnelles Umrüsten dieser Einheit im Gegensatz zum Baukastenprinzip durch Aneinanderketten gemäß Fig. 2 und 3 nicht ohne weiteres möglich ist.In contrast to the modular "chaining together" of individual standard blooms, FIG. 4 shows the construction of a conventional prefabricated block in a design according to the prior art. It can be seen that, in contrast to the modular principle, quick conversion of this unit by chaining together according to FIGS. 2 and 3 is not readily possible.
Figur 5 zeigt den Stammbaum einer Produktionsanlage für Feinstahlprodukte, insbesondere für Drahtabmessungen. Die Anlage weist als Grundausstattung die Fertigstraße (1) mit sechs einzelnen Gerüsten (2 - 7) auf. Erfindungsgemäß ist der Fertigstraße (1) zur Steigerung ihrer Leistungsfähigkeit bzw. zum Ersatz eines wirkungslos gemachten Gerüstes ein zweigerüstiger Vorblock (10) vorgeordnet. Fallweise kann zum gleichen Zweck und/oder zum Nachkalibrieren von Walzgut der Fertigstraße (1) ein zweigerüstiger Vorblock (10') nachgeordnet sein.FIG. 5 shows the family tree of a production plant for fine steel products, in particular for wire dimensions. The basic equipment of the plant is the finishing train (1) with six individual stands (2 - 7). According to the invention, the finishing train (1) is preceded by a two-stand pre-block (10) to increase its performance or to replace a frame that has been rendered ineffective. In some cases, a two-stand pre-block (10 ') can be arranged after the finishing train (1) for the same purpose and / or for recalibrating the rolling stock.
Im Falle einer Produktionsanhebung und/oder zum Ersatz ausgefallener bzw. reparaturbedürftiger Gerüste (2 - 7) kann der Fertigstraße (1) anstelle des zweigerüstigen Vorblocks (10') eine mehrgerüstige Einheit, beispielsweise eine sechs-gerüstige Kombination (12) nachgeordnet sein. Diese kann entsprechend dem Ausführungsbeispiel aus drei zweigerüstigen Grundbausteinen (10) mit einem gemeinsamen Antrieb (20) bestehen. Die Anzahl von Bausteinen (10) einer Einheit richtet sich dabei nach den gegebenen Anforderungen.In the event of a production increase and / or to replace failed or repaired stands (2-7), the finishing train (1) can be followed by a multi-stand unit, for example a six-stand combination (12), instead of the two-stand bloom block (10 '). According to the exemplary embodiment, this can consist of three two-stand basic modules (10) with a common drive (20). The number of building blocks (10) of a unit depends on the given requirements.
Eine weitere Möglichkeit von Leistungs- und Qualitätsaufstockung einer vorhandenen Fertigstraße (1) ist beispielhaft mit der die Fertigstraße (1) überbrückenden Fertigblockeinheit (15) gezeigt. Entsprechend dem in der Figur 5 gezeigten Beispiel kann die Fertigblockeinheit (15) aus vier je zweigerüstigen Vorblöcken (10) zusammengesetzt sein. Die Anzahl der Vorblöcke richtet sich nach dem Walzprogramm. Diese Fertigblockeinheit (15) ermöglicht sehr vorteilhaft eine Anpassung im Baukastensystem an besondere Anforderungen und ergibt die Möglichkeit, gegebenenfalls andere Drahtabmessungen oder andere Materialqualitäten in der Umgehungsschleife (30) zu walzen, während Standard-Qualitäten nach wie vor mit der vorhandenen Fertigstraße (1) gewalzt werden.A further possibility of increasing the performance and quality of an existing finishing train (1) is shown by way of example with the finishing block unit (15) bridging the finishing train (1). According to the example shown in FIG. 5, the prefabricated block unit (15) can be composed of four two-block pre-blocks (10). The number of blooms depends on the rolling program. This finishing block unit (15) very advantageously enables adaptation in the modular system to special requirements and gives the possibility of rolling other wire dimensions or other material qualities in the bypass loop (30), while standard qualities are still rolled with the existing finishing train (1) become.
Insgesamt ergibt die außerordentlich flexible Aus- und Umbaufähigkeit einer vorhandenen Fertigstraße (1) für Feinstahl- oder Drahtabmessungen durch zusätzlich vor- oder nachordenbare Standard-Vorblöcke (10 - 13) einzeln oder in Kombination eine überraschend problemlose Möglichkeit zur Ausweitung und Verbesserung der vorhandenen Walzanlage mit überschaubaren Kosten und relativ sparsamem Platzbedarf, wobei der Um- bzw. Ausbau mit vertretbar geringen Unterbrechungen des laufenden Betriebes durchführbar ist.Overall, the extraordinarily flexible expandability and convertibility of an existing finishing train (1) for fine steel or wire dimensions through additional pre-or post-arrangeable standard blocks (10 - 13), individually or in combination, offers a surprisingly problem-free way of expanding and improving the existing rolling mill manageable costs and relatively economical space requirements, whereby the reconstruction or expansion with justifiable little interruptions of ongoing operations is feasible.
