Abstract
Description
Die Erfindung betrifft eine Produktionsanlage für Feinstahlprodukte, umfassend als Grundausstattung eine Fertigstraße mit mehreren selbständige Einzelantriebe aufweisenden Gerüsten, wobei der Fertigstraße wenigstens ein Standard-Vorblock vor- oder nachordenbar ist.The invention relates to a production plant for Fine steel products, including a basic equipment Finishing line with several independent single drives having scaffolding, the finishing train at least one Standard pre-block can be pre- or post-arranged.
Bei älteren Produktionsanlagen für Feinstahlprodukte 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 older production plants for fine steel products occasionally a need for modernization and / or Increased performance by converting and / or expanding existing ones Finishing train. This is especially true with older ones Rolling mills equipped finishing lines, which with increased demands on quality and / or productivity modern systems cannot keep up and especially if in addition to the existing one Rolling program an increase in quantity and / or From an economic point of view, quality seems desirable and the existing rolling mill is not sufficient for this. Here from an economic point of view, it would be disadvantageous that existing finishing train overall through a new plant replace because the costs incurred are not in economic balance to the expected Production profit stand.
Die EP-A 0 560 093 beschreibt eine Hochleistungs-/Feinstahl-/Drahtstraße mit jeweils mehrere Walzgerüste bzw. Walzeinheiten aufweisender Vorstraße, mindestens einer Zwischenstraße und mit anschließender Fertigstraße, ggf. als Fertigblock für das ein- oder mehradrige Auswalzen von Draht oder von Walzgut mit Rundquerschnitt aus Edelstahl oder sonstigem Legierungsstahl. Diese ist dadurch gekennzeichnet, dass dem Fertigwalzblock ein weiterer mindestens zweigerüstiger Nachwalzblock nachgeordnet ist und dass zwischen dem Fertigwalzblock und dem Nachwalzblock eine temperierende Kühl- und/oder Ausgleichsvorrichtung für das Walzgut zwischengeschaltet ist. Die als Nachwalzblock bezeichnete Nachrüsteinheit, welche der vorhandenen Fertigstraße nachgeschaltet ist, ist mindestens zweigerüstig. Es wird nur ein derartiger Nachwalzblock der Fertigstraße hinzugefügt, und zwar ausschließlich der Fertigstraße nachgeordnet. Dabei wird der Nachwalzblock nicht unmittelbar der Fertigstraße nachgeordnet, sondern unter Zwischenschaltung einer temperierenden Kühl- und/oder Ausgleichsvorrichtung für das Walzgut.EP-A 0 560 093 describes a high performance / fine steel / wire mill each with several roll stands or rolling units showing Vorstraße, at least one intermediate street and with subsequent finishing train, possibly as a finishing block for the single-wire or multi-wire rolling of wire or rolled stock with Round cross-section made of stainless steel or other alloy steel. This is characterized in that the finishing block Subsequent at least two-stand finishing mill is and that between the finishing block and the Roughing block a tempering cooling and / or Compensation device for the rolling stock is interposed. The retrofit unit referred to as the finishing block, which the existing finishing line is at least two-stand. There is only one such roughing block Finishing line added, and only the Finished downstream. The finishing block is not immediately after the finishing train, but under Interposition of a tempering cooling and / or Compensation device for the rolling stock.
Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Produktionsanlage für Feinstahlprodukte der im Oberbegriff von Anspruch 1 genannten Art zur Optimierung von Produktqualität und/oder Leistung der Fertigstraße anzugeben, durch welche 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 unter Verwendung kostengünstiger Standard-Elemente möglich und/oder eine Erweiterung des Produktionsprogrammes erreichbar ist.Starting from the aforementioned prior art, the Invention, the object of a production plant for Fine steel products mentioned in the preamble of claim 1 Way to optimize product quality and / or performance Specify the finishing train through which with as little as possible Effort in costs and with the most economical space requirements and without any noteworthy conversion-related loss of production Increase in product quality and / or performance of the Finishing line using less expensive Standard elements possible and / or an extension of the Production program is achievable.
Zur Lösung der Aufgabe wird bei einer Produktionsanlage für Feinstahlprodukte der im Oberbegriff von Anspruch 1 genannten Art mit der Erfindung vorgeschlagen, dass die Fertigstraße zur Steigerung ihrer Leistungsfähigkeit bzw. zum Ersatz eines wirkungslos gemachten Gerüstes mit einer nach Walzprogramm aus einer bestimmbaren Anzahl je zweigerüstiger Grundbausteine zusammensetzbaren Fertigblockeinheit mit einer gemeinsamen Antriebseinheit überbrückbar ist.The solution to the problem is at a production plant for Fine steel products mentioned in the preamble of claim 1 Art proposed with the invention that the finishing train for Increase their performance or to replace one ineffectively rendered scaffolding with one according to the rolling program a determinable number of two-stand basic building blocks assembled prefabricated block unit with a common Drive unit can be bridged.
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 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.In the two-stand design known as the standard bloom block Plant part is a mature and proven Basic element in the form of a building block, this Basic element, for example, by stringing together several such building blocks into a multi-unit put together and without adaptation problems to one with any number of scaffolding trained Wire finishing train can be expanded. For example a single basic building block for post-tolerance Wire dimensions must be subordinate to the finishing train. Can too in older scaffolding of a finishing train, if scaffolding z. B. temporarily fail during repairs, which are then missing Rolling capacity by pre- or retrofitting one or more Standard blocks are compensated. It follows due to the variable use of two-stand standard blocks in a modular arrangement, a number cost-effective and quickly feasible options for Performance maintenance, to increase performance and / or Increasing the quality of an existing finishing train.
Eine Ausgestaltung der Erfindung sieht vor, dass Fertigblockeinheiten zur Anpassung einer vorhandenen Fertigstraße im Baukastensystem an besondere Anforderungen, z. B. andere Drahtabmessungen oder andere Materialqualitäten, in einer Umgehungsschleife anordenbar sind. An embodiment of the invention provides that Prefabricated block units to adapt an existing one Finishing line in the modular system to special requirements, e.g. B. other wire dimensions or other material qualities, in a bypass loop can be arranged.
Eine weitere Ausgestaltung sieht vor, dass jeweils ein einzelner zweigerüstiger Standard-Vorblock als Baustein mit weiteren von Standard-Vorblocken gebildeten Bausteinen verbindbar und durch ein gemeinsames Antriebsaggregat zu einer beliebigen Fertigblockeinheit kombinierbar ist.A further embodiment provides that one single two-stand standard block as a building block with other building blocks formed by standard blooms connectable and by a common drive unit to one any finished block unit can be combined.
Nach einer anderen Ausgestaltung der Erfindung ist vorgesehen, dass wirkungslos gemachte Gerüste der Fertigstraße durch wenigstens einen Standard-Vorblock ersetzbar sind.According to another embodiment of the invention, that ineffective scaffolding through the finishing train at least one standard bloom block can be replaced.
Eine nach der Erfindung ausgebildete Produktionsanlage kann wenigstens einen der Fertigstraße vor- oder nachgeordneten Standard-Vorblock und/oder fallweise eine Überbrückung durch Standard-Vorblöcke aufweisen, und ein solcher Umbau- bzw. Ausbausatz kann in überraschend unkomplizierter Weise nach dem Baukastenprinzip der Fertigstraße angegliedert sein.A production plant designed according to the invention can at least one upstream or downstream of the finishing train Standard pre-block and / or occasionally bridging Have standard blooms, and such a conversion or Extension kit can be surprisingly straightforward after 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).Figure 1 shows a single two-column bloom block (10) as any combinable building block for pre or post 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), assembled from two two-stand standard blooms (10). These are by means of a common drive unit (20) connected.
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 consists of four modular strings Standard blooms (10) with a common drive (20) together.
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 uncomplicated overall Combination options for multi-stand units under Use of standard blooms (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.Through "chaining together" from blooms to finished blocks can in this way four, six, eight and occasionally ten-stand system parts put together and existing ones Plant parts can be supplemented or expanded further.
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.Figure 4 shows in contrast to the modular "Linking together" of individual standard blocks Construction of a conventional prefabricated block in one State-of-the-art design. It can be seen that a quick changeover of this unit in contrast to the Modular principle by chaining together according to FIGS. 2 and 3 is not easily 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. Figure 5 shows the family tree of a production plant for Fine steel products, especially for wire dimensions. The The system has the finishing train (1) as basic equipment six individual scaffolds (2 - 7). According to the invention Finishing line (1) to increase their performance or to replace an ineffective scaffold upstream of the two-stand block (10). Occasionally can same purpose and / or for the recalibration of the rolling stock Finishing line (1) a two-stand bloom (10 ') be subordinate.
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 replacement failed or repaired scaffolding (2 - 7) can the finishing train (1) instead of the two-stand bloom (10 ') a multi-stand unit, for example one six-stand combination (12). This can according to the embodiment from three two-stand Basic components (10) with a common drive (20) consist. The number of building blocks (10) of a unit judges according to 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.Another way of performance and Quality increase of an existing finishing train (1) is for example with the one that bridges the finishing train (1) Prefabricated block unit (15) shown. Corresponding to that in the figure 5 example, the prefabricated block unit (15) can consist of four be composed of two-stand blooms (10). The The number of blooms depends on the rolling program. This Prefabricated block unit (15) very advantageously enables one Adaptation in the modular system to special requirements and gives the possibility of other wire dimensions if necessary or other material qualities in the bypass loop (30) to roll while standard grades still with the existing finishing train (1) are rolled.
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 education and training Convertibility of an existing finishing train (1) for Fine steel or wire dimensions by additional pre or subsequent standard blocks (10 - 13) individually or in Combination is a surprisingly easy way to Expansion and improvement of the existing rolling mill with manageable costs and relatively economical space requirements, whereby the conversion or expansion with justifiable small interruptions of ongoing operations is feasible.
