Description

Die Erfindung betrifft ein Verfahren und eine Fertigungslinie zum Herstellen von Metallbändern aus Kupfer oder Kupferlegierungen durch Gießen und Walzen.The invention relates to a method and a production line for producing metal strips of copper or copper alloys by casting and rolling.

Bisher werden solche Metallbänder aus Weichmetallen wie bspw. Kupfer oder Kupferlegierungen, durch Gießen in Blockform erzeugt ( US-A 5 140 837 ). Nach dem Abkühlen muss der Block erneut erwärmt und in einem Warmwalzverfahren auf die geforderte Dicke gebracht werden. An das Warmwalzen anschließend erfolgt ein Fräsen an der Ober und Unterseite und ein Inspizieren und Aufrollen zu einem Bundring. Von einem Bundringablauf gelangt das Metallband in ein Reversiergerüst und wird nach einem Kaltwalzverfahren zum Bundring gewickelt und in Bundring-Form in einer Haubenglüheinrichtung zur Gefügeverfeinerung geglüht oder in abgewickelter Form im Durchlauf geglüht, danach gebeizt, gewaschen, getrocknet, dressiert und die Oberfläche wiederum vor dem Bundring-Wickeln inspiziert.So far, such metal strips of soft metals such as. Copper or copper alloys, produced by casting in block form ( US-A 5,140,837 ). After cooling, the block must be reheated and brought to the required thickness in a hot rolling process. The hot rolling is followed by a milling on the top and bottom and an inspection and rolling up to a collar. From a collar ring the metal strip passes into a reversing mill and is wound by a cold rolling process to the collar and annealed in Bundring-form in a bell annealing device for microstructure refining or annealed in unwound form in the pass, then pickled, washed, dried, dressed and the surface in turn before Bundle winding is inspected.

Die hierzu aufzuwendenden Betriebskosten und Investitionskosten für einen Neubau sowie die Anlagengestaltung bei vorhandenen nutzbaren Grundflächen sind grundsätzlich sehr hoch. In horizontaler Gießtechnik werden Metallbänder aus Kupfer oder Kupferlegierungen gegossen und kaltgewalzt mit bspw. 15 - 20 000 t /Jahr, und zwar deutlich geringeren Investitionskosten.The operating costs and investment costs for a new building as well as the design of the existing usable floor space are basically very high. In horizontal casting technique, metal strips of copper or copper alloys are cast and cold rolled with, for example, 15-20,000 t / year, and indeed significantly lower investment costs.

Eine Kapazitätssteigerung, die derzeit vom Markt gefordert wird (von 30.000 - 70 000 t/Jahr) ist mit den derzeitigen Kosten nicht mehr wirtschaftlich zu erreichen.An increase in capacity currently required by the market (from 30,000 to 70,000 t / year) can no longer be achieved economically with the current costs.

Der Erfindung liegt die Aufgabe zugrunde, die geforderte Kapazitätssteigerung in Verbindung mit geringeren Betriebskosten und reduzierten Anlagen-Investitionsko-sten dennoch zu erzielen.The invention has for its object to still achieve the required capacity increase in conjunction with lower operating costs and reduced investment Anlagenko costs.

Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Schmelze in einem vertikalen und / oder horizontalen Bandstranggießprozess zum Kupferband vergossen wird, das Kupferband durch Fräsen an der Ober- und Unterseite gereinigt wird, einem Kaltwalzprozess unterzogen und versandbereit gemacht wird, oder nach Glühen, Beizen, Waschen und Trocknen und ggf. einem Dressierwalzschritt einer Inspektion unterzogen und dann versandbereit gemacht wird. Die Vorteile sind, dass eine Blockgießvorrichtung, das Erwärmen des Blocks auf Walztemperatur und das Warmwalzen völlig eingespart werden. Weiter ist vorteilhaft, dass der Kaltwalzprozess an die geplanten Produktionsmengen flexibel angepasst werden kann, bspw. dadurch, dass die Kaltwalzung auf optimale Bandtemperatur im Auslauf gefahren werden kann.The above object is achieved in that the melt is cast in a vertical and / or horizontal Bandstranggießprozess to copper tape, the copper strip is cleaned by milling on the top and bottom, subjected to a cold rolling process and made ready to ship, or after annealing, pickling , Washing and drying and, if necessary, a temper rolling step of an inspection and then made ready for shipment. The advantages are that a block caster, the heating of the block to rolling temperature and the hot rolling are completely eliminated. It is also advantageous that the cold rolling process can be flexibly adapted to the planned production quantities, for example by virtue of the fact that the cold rolling can be driven to the optimum strip temperature in the outlet.

Eine Ausgestaltung ergibt sich dadurch, dass aus inspizierten Bundringen stapelweise Bleche durch Querteilen des Kupferbandes hergestellt werden.One embodiment results from the fact that from inspected waist rings stacked sheets are produced by cutting the copper strip.

Ebenso besteht eine Weiterbildung darin, dass aus inspizierten Bundringen durch Längsteilen aufrollbare Kupferband-Streifen hergestellt werden.Likewise, there is a further development that made of inspected waist rings by longitudinal parts roll-up copper strip strips are made.

Die Temperaturführung kann vorteilhaft dadurch vorgenommen werden, dass beim Kaltwalzen das Kupferband auf der Einlaufseite mit Öl geschmiert und auf der Auslaufseite mit kalten oder tiefkalten inerten Gasen gekühlt wird. Es können unterschiedliche Medien zum Kühlen herangezogen werden.The temperature control can be advantageously carried out by the fact that during cold rolling the copper strip is lubricated on the inlet side with oil and cooled on the outlet side with cold or cryogenic inert gases. Different media can be used for cooling.

Dabei ist es vorteilhaft, dass die Sollwert-Vorgabe für die Walzparameter auf eine maximale Bandtemperatur von 120 °C eingestellt wird. Dadurch können die Parameter (Istwerte) für Gießen und Fräsen an den Walzprozess gekoppelt werden.It is advantageous that the setpoint specification for the rolling parameters is set to a maximum strip temperature of 120 ° C. This allows the parameters (actual values) for casting and milling to be coupled to the rolling process.

Das Verfahren kann noch dadurch verbessert werden, dass auf Fertigbanddicke temperaturgeführte, kaltgewalzte Kupferband-Bundringe entweder in einer Hauben-Glüheinrichtung in Bundring-Form oder im Durchlauf-Glühverfahren in der Gefügestruktur weiter verfeinert, danach gebeizt, gewaschen, getrocknet und an der Oberfläche inspiziert und in Bundring-Form weiterverarbeitet werden.The process can be further improved by further refining to finished strip thickness temperature-controlled, cold-rolled copper band collar rings either in a bell annealing device in collar shape or continuous annealing in the microstructure, then pickled, washed, dried and inspected on the surface and be processed in a bundle ring form.

Die Fertigungslinie zur Herstellung von Metallbändern aus Kupfer oder Kupferlegierung mit zumindest einer Schmelzeinrichtung, einer Gießeinrichtung und einer Walzeinrichtung ist vorzugsweise für eine Kaltverformung von 23 mm bis 0,2 mm Kupferbanddicke gestaltet.The production line for the production of metal strips of copper or copper alloy with at least one melting device, a casting device and a rolling device is preferably designed for a cold deformation of 23 mm to 0.2 mm copper strip thickness.

Zur Lösung der gestellten Aufgabe wird vorrichtungstechnisch vorgeschlagen, dass auf die Schmelzeinrichtung folgend in Fertigungsrichtung hintereinander zumindest eine vertikale Bandstranggieß-Einrichtung und / oder eine horizontale Bandstranggieß-Einrichtung, eine unmittelbar anschließende Fräseinrichtung, eine Bundabrolleinrichtung, eine Kaltwalzeinrichtung, eine Bundaufrolleinrichtung und eine Glüheinrichtung in Folge hintereinander angeordnet sind. Eine Gießvorrichtung für Blöcke, die abkühlen und in einem Ofen wieder auf Walztemperatur erwärmt werden müssen und ein Warmwalzgerüst selbst entfallen völlig. Dadurch werden beim Bau der Fertigungslinie nicht nur geringere Investitionskosten, sondern während des Betriebs geringere Betriebskosten (geringere Reparaturkosten und Reparaturzeiten) verlangt, denen eine höhere Leistungsfähigkeit der Anlage gegenübersteht.To achieve the object, device technology proposes that following the melting device in the production direction one behind the other at least one vertical Bandstranggieß device and / or a horizontal Bandstranggieß device, an immediately adjacent milling device, a Bundabrolleinrichtung, a cold rolling device, a Bundaufrolleinrichtung and a glow device in a row arranged one behind the other. A casting device for blocks, which must be cooled and heated in an oven to rolling temperature and a hot rolling mill itself completely eliminated. As a result, not only lower investment costs are required in the construction of the production line, but lower operating costs (lower repair costs and repair times) during operation, which are offset by a higher performance of the plant.

Im weiteren Verlauf der Fertigungslinie ergeben sich zusätzliche Vorteile:In the further course of the production line there are additional advantages:

Die Kaltwalzeinrichtung besteht aus einem Reversiergerüst.The cold rolling device consists of a reversing stand.

Die Fräseinrichtung schließt unmittelbar an die vertikale Bandstranggieß-Einrichtung an. Das Kupferband läuft vorteilhafterweise direkt in die nächste Einrichtung ein.The milling device connects directly to the vertical Bandstranggieß device. The copper strip advantageously runs directly into the next device.

Die vertikale Bandstranggieß-Einrichtung, die Fräseinrichtung und das Reversiergerüst schließen unmittelbar aneinander an. Das Kupferband läuft ohne Unterbrechung in die nachfolgende Einrichtung ein.The vertical Bandstranggieß device, the milling device and the Reversiergerüst close to each other directly. The copper tape runs without interruption in the subsequent device.

Die Kaltwalzeinrichtung besteht aus einem Tandemgerüst.The cold rolling device consists of a tandem framework.

Die vertikale Bandstranggieß-Einrichtung, die Fräseinrichtung und das Tandemgerüst schließen unmittelbar aneinander an. Das Kupferband läuft ohne Unterbrechung von Einrichtung zu Einrichtung.The vertical Bandstranggieß device, the milling device and the tandem stand close to each other directly. The copper tape runs uninterrupted from device to device.

Für höhere Walzleistungen ist es vorteilhaft, dass dem Tandemgerüst zwei parallel an- und vorgeordnete vertikale Bandstranggieß-Einrichtungen mit Fräseinrichtungen zugeordnet sind.For higher rolling performance, it is advantageous that the tandem structure are assigned two parallel upstream and upstream vertical Bandstranggieß devices with milling equipment.

Eine höhere Gießleistung gegenüber der Walzeinrichtung kann dadurch erreicht werden, dass dem Tandemgerüst jeweils eine vertikale und eine horizontale Bandstranggieß-Einrichtung jeweils mit einer unmittelbar folgenden Fräseinrichtung vorgeordnet sind.A higher casting performance compared with the rolling device can be achieved by arranging in each case one vertical and one horizontal belt continuous casting device, each with an immediately following milling device, on the tandem stand.

Bei zwei Gießeinrichtungen ist die Fertigungslinie derart gestaltet, dass bei zwei parallel gießenden vertikalen Bandstranggieß-Einrichtungen auf die jeweilige Fräseinrichtung jeweils ein Reversiergerüst folgt.In the case of two pouring devices, the production line is designed in such a way that, in the case of two vertical continuous strip casting devices which cast in parallel, a respective reversing stand follows the respective milling device.

Eine andere Kombination für Gießen / Fräsen und Walzen ist dadurch gegeben, dass bei fertigungsparallelen vertikalen und horizontalen Bandstranggieß-Einrichtungen jeweils ein Reversiergerüst folgt.Another combination for casting / milling and rolling is given by the fact that in production parallel vertical and horizontal Bandstranggieß facilities each followed by a Reversiergerüst.

Für alle Kombinationen der Fertigungslinie ist vorgesehen, dass die Glüheinrichtung jeweils entweder aus einer Hauben-Glüheinrichtung für Bundringe oder aus einer Durchlaufglüh-Einrichtung als Schwebebandofen ausgebildet ist.For all combinations of the production line it is provided that the annealing device is designed in each case either from a hood glowing device for collar rings or from a continuous annealing device as a floating belt furnace.
