Description

Gebiet der TechnikField of engineering

Die Erfindung betrifft ein Verfahren gemäß dem Oberbegriff des Patentanspruchs 1 zur Probennahme von einem mittels Warmwalzprozess warmgewalzten Metallband, welches mittels Wickelprozess zu einem Bund aufgehaspelt wird, sowie eine Vorrichtung zur Durchführung des Verfahrens gemäß dem Oberbegriff der Patentansprüche 2 und 3.The invention relates to a method according to the preamble of patent claim 1 for sampling of a hot-rolled by hot rolling metal strip, which is wound by means of winding process into a federal government, and an apparatus for performing the method according to the preamble of claims 2 and 3.

Ein derartiges Verfahren und eine derartige Vorrichtung gehen beispielsweise aus der WO 2004/060589 A1 hervor.Such a method and such a device, for example, from the WO 2004/060589 A1 out.

Stand der TechnikState of the art

Bei der Herstellung warmgewalzter Metallbänder ist es üblich, diese zu Bunden zu haspeln und für die weitere Verarbeitung bereitzustellen.In the manufacture of hot rolled metal strip, it is common to coackle them into bundles and provide them for further processing.

Es besteht die Notwendigkeit, die zu Bunden gehaspelten warmgewalzten Metallbänder zu inspizieren beziehungsweise zu beproben, also Probestücke von den Bunden zu entnehmen. Je dicker und je härter die warmgewalzten Metallbänder sind, desto größer werden die Probleme beim Aufhaspeln und Binden der aufgehaspelten Bunde. Ein Öffnen solcher Bunde zwecks Probennahme - mit nachfolgendem abermaligem Binden, wobei das zur Probennahme freigemachte warmgewalzte Metallbandende wieder komplett an den Bund herangebogen werden muss - wird daher immer schwieriger und gefährlicher.There is a need to inspect or sample the coils of hot-rolled metal strips that have been wound into coils, ie to remove specimens from the coils. The thicker and harder the hot rolled metal strips are, the greater the problems of coiling and binding the coiled bundles. Opening such bundles for the purpose of sampling - with subsequent re-binding, whereby the freed for sampling hot rolled metal band end must be brought back completely to the federal government - is therefore increasingly difficult and dangerous.

Aus dem Stand der Technik sind eine Vielzahl von Vorrichtungen zur Probennahme von zu Bunden gehaspelten warmgewalzten Metallbändern bekannt. In der Regel wird dabei eine Probe von den äußeren Windungen des Bundes entnommen. Beispielsweise ist in EP0044923B1 eine Vorrichtung zur Probennahme von einem zu einem Bund gehaspelten Metallband zu entnehmen. Die äußere Windung wird durch einen Bundöffner und Führungseinrichtungen in senkrechter Lage einer Schere zugeführt. Nachteilig ist dabei vor allem, dass die freie Bandlänge, die das Metallband von der in Drehrichtung gesehen hinteren Lagerrolle bis zu den Führungseinrichtungen beziehungsweise zur Schere zurücklegt, sehr groß ist, sodass eine ausreichende Führung des freien Bandendes nicht sicher gegeben ist. Insbesondere bei dickeren und festeren Metallbändern kann dies zu Störungen führen beziehungsweise die Probennahme erschweren.A variety of devices for sampling bundled hot-rolled metal strips are known in the art. As a rule, a sample is taken from the outer coils of the federal government. For example, in EP0044923B1 to take a device for sampling of a metal band coiled to a federal government. The outer turn is fed by a Bundöffner and leadership institutions in a vertical position scissors. The disadvantage is here all, that the free length of tape that covers the metal strip from the rear seen in the direction of rotation rear bearing roller to the guide devices or scissors, is very large, so that a sufficient guidance of the free end of the tape is not sure. Especially with thicker and stronger metal bands, this can lead to disturbances or make sampling more difficult.

In WO2006111259A1 und WO2012126631A1 werden ebenfalls Vorrichtungen vorgestellt, die schon besser für eine sichere Probennahme auch bei höher festen beziehungsweise dicken Bändern geeignet sind, allerdings zur Probennahme auch einen aufgehaspelten Bund teilweise abwickeln müssen. Abwickeln des Metallbandes wirft besonders bei höher festen beziehungsweise dicken warmgewalzten Bändern Probleme auf, denn das Metallband steht im aufgehaspelten Bund unter elastischer Spannung. Ein Öffnen des Bundes zwecks Abwicklung zur Probennahme führt daher ein Sicherheitsrisiko bedingt durch das auffedernde Metallband mit sich. Weiterhin ist es nach der Probennahme äußerst schwierig und nur unter Aufbietung großer Kräfte - welche die entsprechenden Anlagen belasten und die Qualität des Metallbandes beeinträchtigen können - möglich, die Probe zu entnehmen und das freie Metallbandende wieder komplett an den Bund heranzubiegen.In WO2006111259A1 and WO2012126631A1 Also devices are presented, which are already better for a safe sampling even with high-strength or thick tapes are suitable, but for sampling also have to unwind a coiled bundle partially. Unwinding of the metal strip raises problems, especially in the case of higher-strength or thick hot-rolled strips, because the metal strip is under elastic tension in the coiled-up bundle. Opening the federal government for the purpose of processing for sampling therefore carries a security risk due to the auffedernde metal strip with it. Furthermore, after sampling, it is extremely difficult and only with the use of large forces - which can burden the corresponding facilities and affect the quality of the metal strip - possible to remove the sample and turn back the free metal band end completely to the federal government.

Zusammenfassung der ErfindungSummary of the invention Technische AufgabeTechnical task

Es ist die Aufgabe der vorliegenden Anmeldung, ein Verfahren und eine Vorrichtung zur Probennahme bereitzustellen, bei denen die genannten Probleme bei dicken und höher festen warmgewalzten Metallbändern vermieden werden.It is the object of the present application to provide a method and a device for sampling, in which the problems mentioned are avoided with thick and higher-strength hot-rolled metal strips.

Technische LösungTechnical solution

Diese Aufgabe wird gelöst durch ein Verfahren gemäß dem Patentanspruch 1 zur Probennahme von einem mittels Warmwalzprozess in einer Warmwalzstrasse warmgewalzten Metallband, welches mittels Wickelprozess zu einem Bund aufgehaspelt wird,
wobei die Probe von einem Endbereich des warmgewalzten Metallbandes genommen wird, nachdem der Warmwalzprozess abgeschlossen wurde, und bevor der der erstmals stattfindende Wickelprozess des fertig warmgewalzten Metallbandes in der Warmwalzstrasse abgeschlossen ist. Erfindungsgemäß wird die Probe genommen, nachdem das Bandende des warmgewalzten Metallbandes die "pass-line" der Warmwalzstraße verlassen hat.This object is achieved by a method according to claim 1 for sampling of a hot-rolled by means of hot rolling in a hot rolling mill metal strip, which is wound by means of winding process into a federal government,
wherein the sample is taken from an end portion of the hot-rolled metal strip after the hot rolling process has been completed, and before the initial winding process of the finished hot-rolled metal strip in the hot rolling line is completed. According to the invention, the sample is taken after the strip end of the hot-rolled metal strip has left the "pass-line" of the hot rolling line.

Der Endbereich des warmgewalzten Metallbandes, von dem die Probe genommen wird, ist das Bandende.The end portion of the hot rolled metal strip from which the sample is taken is the ribbon end.

Die Probe wird also "in-line" genommen, also innerhalb der Warmwalzstrasse; ein mittels des in der Warmwalzstrasse erstmals stattfindenen Wickelprozesses fertig aufgehaspelter Bund wird nicht aus der Haspelstation entnommen, an eine andere Stelle verfahren, und dort nach Öffnung des Bundes eine Probe aus seinem Endbereich entnommen.The sample is thus taken "in-line", ie within the hot rolling mill; a wound up by means of the first take place in the hot rolling line winding process finished coil is not removed from the coiler station, moved to another location, and there taken after opening the federal a sample from its end.

Das warmgewalzte Metallband ist vorzugsweise ein Stahlband. Dabei handelt es sich bevorzugt um ein Stahlband mit einer Dicke > 15 mm, und/oder aus hochfestem Feinkornbaustahl, und/oder aus ultrahochfestem Stahl.The hot-rolled metal strip is preferably a steel strip. It is preferably a steel strip with a thickness> 15 mm, and / or high-strength fine-grained structural steel, and / or ultra-high-strength steel.

Vorteilhafte Wirkungen der ErfindungAdvantageous Effects of the Invention

Erfindungsgemäß wird die Probennahme durchgeführt, nachdem der Warmwalzprozess abgeschlossen wurde und bevor der Wickelprozess abgeschlossen ist, also bevor das fertig warmgewalzte Metallband vollständig zu einem Bund aufgehaspelt ist. Der Wickelprozess in der Haspelstation ist abgeschlossen, wenn der Bund zur Entnahme aus der Haspelstation fertiggestellt ist.According to the invention, the sampling is carried out after the hot rolling process has been completed and before the winding process is completed, that is, before the finished hot-rolled metal strip is completely wound into a bundle. The winding process in the coiler station is completed when the bundle is ready for removal from the coiler station.

Das Ende des warmgewalzten Metallbandes, von dem die Probe genommen wurde, wird nach der Probennahme wie bisher aufgehaspelt. Durch die erfindungsgemäße Vorgehensweise ist es nicht mehr notwendig, zwecks Probennahme einen aufgehaspelten Bund zu öffnen. Die mit einer solchen Öffnung verbundenen Probleme können daher vermieden werden. Während die Probennahme erfolgt, wird der Bund von der Haspelstation derart gehalten, dass keine durch Öffnung des bereits aufgehaspelten Teils des Bundes auftretende Probleme entstehen.The end of the hot rolled metal strip from which the sample was taken is rewound after sampling as before. Due to the procedure according to the invention, it is no longer necessary to open a coiled bundle for the purpose of sampling. The problems associated with such an opening can therefore be avoided. While taking the sample, the bundle is taken from the coiler station held such that no problems arise by opening the already wound part of the federal government problems.

Ein weiterer Gegenstand der vorliegenden Anmeldung ist eine Vorrichtung gemäß dem Patentanspruch 2 zur Durchführung des erfindungsgemäßen Verfahrens. Eine solche ist eine Produktionsvorrichtung für warmgewalztes Metallband, umfassend zumindest eine Warmwalzstraße, mit zumindest einer Haspelstation,
wobei sie auch umfasst eine Probennahmevorrichtung zur Probennahme von teilweise aufgewickeltem warmgewalztem Metallband in der das warmgewalzte Metallband aufwickelnden Haspelstation, wobei die Probennahmevorrichtung zur Probennahme von teilweise aufgewickeltem warmgewalztem Metallband außerhalb, bevorzugt unterhalb, der "pass-line" der Warmwalzstraße angeordnet ist.Another object of the present application is a device according to claim 2 for carrying out the method according to the invention. One such is a production device for hot-rolled metal strip, comprising at least one hot rolling line, with at least one coiling station,
it also comprises a sampling device for sampling partially wound hot rolled metal strip in the hot rolled metal strip winding reel station, the sampling device for sampling partially wound hot rolled metal strip outside, preferably below, the "pass line" of the hot rolling line.

Warmgewalztes Metallband wird in Produktionsvorrichtungen hergestellt, die eine oder mehrere Warmwalzstrassen, sowie einen oder mehrere Treiber mit jeweils zugeordneten Haspelstationen umfassen. Die Treiber mit jeweils zugeordneten Haspelstationen sind im Endbereich der Warmwalzstraße angeordnet. Hinter einem solchen Treiber wird das den Treiber verlassende warmgewalzte Metallband in der zugeordneten Haspelstation zu einem Bund aufgewickelt - auch genannt aufgehaspelt.Hot rolled metal strip is manufactured in production equipment comprising one or more hot rolling lines, as well as one or more drivers each having associated coiler stations. The drivers, each with associated coiler stations are arranged in the end of the hot rolling mill. Behind such a driver, the hot-rolled metal strip leaving the driver is wound up into a bundle in the assigned coiling station - also called reeled.

Ein Treiber, der einer Haspelstation zugeordnet ist, dient ausschließlich dazu, das Metallband in die Haspelstation umzulenken und in den Haspel der Haspelstation zu treiben, und nachfolgend mittels Bandzug einen straff gewickelten sogenannten Warmbund sicherzustellen. Zwischen diesem Treiber und der ihm zugeordneten Haspelstation befindet sich kein weiterer Treiber.A driver, which is assigned to a reel station, serves exclusively to deflect the metal strip into the coiler station and to drive it into the reel of the coiler station, and subsequently to ensure a tightly wound so-called warm bundle by means of strip tension. There is no other driver between this driver and the reel station assigned to it.

Ein Treiber und zugeordnete Haspelstation können auch als Teil einer Haspelanlage, welche zusätzlich auch eine dem Treiber vorgeschaltete Einlaufführung wie beispielsweise ein Einlauflineal umfasst, bezeichnet werden.A driver and assigned coiling station can also be referred to as part of a coiler, which additionally also includes an inlet guide upstream of the driver, such as an infeed ruler.

Treiber und Haspelstation sind sich dabei gegenseitig zugeordnet; beispielsweise ist ein Treiber A einer Haspelstation A' zugeordnet, und die Haspelstation A' dem Treiber A zugeordnet.Driver and coiler station are mutually assigned; For example, a driver A is assigned to a coiler station A ', and the coiler station A' is assigned to the driver A.

Es kann in der Produktionsvorrichtung auch andere Treiber geben, die keiner Haspelstation zugeordnet sind.There may also be other drivers in the production device that are not associated with a coiler station.

Erfindungsgemäß ist vorgeschlagen, in der Haspelstation eine Probennahmevorrichtung zur Probennahme von teilweise aufgehaspeltem warmgewalztem Metallband vorzusehen. Dadurch kann die Probe von einem Endbereich des warmgewalztem Metallbandes genommen werden, bevor der Wickelprozess abgeschlossen ist. Erfindungsgemäß ist die Probennahmevorrichtung außerhalb der "pass-line", beispielsweise unterhalb oder oberhalb, der Warmwalzstraße angeordnet.According to the invention, it is proposed to provide a sampling device in the coiling station for sampling partially coiled, hot-rolled metal strip. This allows the sample to be taken from an end portion of the hot rolled metal strip before the wrapping process is complete. According to the invention, the sampling device is arranged outside the "pass line", for example below or above, the hot rolling line.

Ein weiterer Gegenstand der vorliegenden Anmeldung ist eine weitere Vorrichtung gemäß dem Patentanspruch 3 zur Durchführung des erfindungsgemäßen Verfahrens. Eine solche ist eine Produktionsvorrichtung für warmgewalztes Metallband, umfassend zumindest eine Warmwalzstraße, mit einer Haspelstation und einem dieser Haspelstation zugeordneten Treiber,
wobei sie auch umfasst eine Probennahmevorrichtung zur Probennahme von teilweise aufgewickeltem warmgewalztem Metallband zwischen einer unteren Treibrolle des dieses warmgewalzte Metallband treibenden Treibers und der das warmgewalzte Metallband aufwickelnden Haspelstation,
wobei die Probennahmevorrichtung zur Probennahme von teilweise aufgewickeltem warmgewalztem Metallband außerhalb, bevorzugt unterhalb, der "pass-line" angeordnet ist.Another object of the present application is a further device according to claim 3 for carrying out the method according to the invention. One such is a production device for hot-rolled metal strip, comprising at least one hot rolling line, with a coiling station and a driver assigned to this coiling station,
it also comprises a sampling device for sampling partially wound hot-rolled metal strip between a lower drive roller of the driver driving this hot-rolled metal strip and the coiling station winding the hot-rolled metal strip,
wherein the sampling device for sampling partially wound hot rolled metal strip outside, preferably below, the "pass-line" is arranged.

Erfindungsgemäß ist vorgeschlagen, zwischen der unteren Treibrolle des Treibers, der ein warmgewalztes Metallband in die Haspelstation treibt und der dieses warmgewalzte Metallband aufwickelnden Haspelstation eine Probennahmevorrichtung zur Probennahme von teilweise aufgehaspeltem warmgewalztem Metallband vorzusehen. Dadurch kann die Probe von dem Endbereich des warmgewalztem Metallbandes, dem Bandende, genommen werden, bevor der Wickelprozess abgeschlossen ist. Erfindungsgemäß ist die Probennahmevorrichtung außerhalb der "pass-line", beispielsweise unterhalb oder oberhalb, der Warmwalzstraße angeordnet.According to the invention, it is proposed to provide a sampling device for sampling partly coiled hot rolled metal strip between the lower drive roller of the driver, which drives a hot rolled metal strip into the coiling station, and the coiling station which winds up this hot rolled metal strip. This allows the sample to be taken from the end portion of the hot rolled metal strip, the strip end, before the wrapping process is complete. According to the invention, the sampling device is outside the "pass line", for example below or above, arranged the hot rolling mill.

Die Probennahmevorrichtung zur Probennahme von teilweise aufgewickeltem warmgewalztem Metallband ist außerhalb der sogenannten "pass-line", also dem Walzniveau - also der Oberkante der Rollen des Rollgangs der Warmwalzstraße -, des Ausgangsmetallbandes auf der Warmwalzstraße angeordnet. Auf diese Weise befindet sich das Ende des warmgewalzten Metallbandes, an dem die Probennahme erfolgt, außerhalb, bevorzugt unterhalb, der sogenannten "Pass line" der Warmwalzstraße. Deshalb kann gegebenenfalls ein nachfolgendes warmgewalztes Metallband - das einer anderen Haspelstation zugeführt wird - ohne Behinderung zu einer weiteren Haspelanlage weitergeführt und zu einem Bund gewickelt werden. Das Warmwalzen des nachfolgenden Metallbandes wird also nicht behindert durch die Probennahme.The sampling device for sampling partially wound hot rolled metal strip is outside the so-called "pass-line", so the rolling level - ie the upper edge of the rollers of the roller table of the hot rolling mill -, arranged the output metal strip on the hot rolling mill. In this way, the end of the hot-rolled metal strip on which the sampling takes place outside, preferably below, the so-called "pass line" of the hot rolling mill. Therefore, if necessary, a subsequent hot-rolled metal strip - which is fed to another coiler station - be continued without hindrance to another coiler and wound into a bundle. The hot rolling of the subsequent metal strip is thus not hindered by the sampling.

Vorzugsweise handelt es sich bei den in Warmwalzwerken eingesetzten Haspelstationen um Schwingenhaspel.Preferably, the reel stations used in hot rolling mills are swinging reels.

Beschreibung von AusführungsformenDescription of embodiments

Figur 1 zeigt, wie ein warmgewalztes Stahlband 1, welches von einem Treiber 2 mit oberer Treibrolle 3 und unterer Treibrolle 4 nach dem zugehörigen Warmwalzprozess über einen Rollgang 5 einer Warmwalzstraße getrieben wurde, in einer dem Treiber 2 zugeordneten Haspelstation 8 in einem Wickelprozess in der Warmwalzstraße erstmals zu einem Bund 9 aufgehaspelt wird. Außerhalb der "pass-line" 6 des warmgewalzten Stahlbandes 1 auf dem Rollgang 5 der Warmwalzstraße, in dem Raumbereich zwischen der unteren Treibrolle 4 des Treibers 2 und der diesem zugeordneten, das warmgewalzte Stahlband 1 aufhaspelnden Haspelstation 8, ist eine Probennahmevorrichtung 10 zur Probennahme von dem teilweise aufgehaspeltem warmgewalztem Stahlband 1 vorhanden. Es ist gezeigt das Ende des warmgewalzten Stahlbandes 1, welches noch nicht auf den Bund 9 aufgewickelt ist, sondern noch von ihm absteht. Von diesem Ende wird in dem dargestellten Moment mittels Probennahmevorrichtung 10 ein Stück als Probe 11 vom warmgewalztem Stahlband 1 abgetrennt, bevor das warmgewalzte Stahlband 1 in der Haspelstation 8 vollständig zum Bund 9 aufgewickelt wird. FIG. 1 shows how a hot rolled steel strip 1, which was driven by a driver 2 with upper drive roller 3 and lower drive roller 4 after the associated hot rolling process via a roller table 5 a hot rolling mill in a winding station 8 associated with the driver 2 in a winding process in the hot rolling mill for the first time a Bund 9 is wound up. Outside the "pass-line" 6 of the hot-rolled steel strip 1 on the roller table 5 of the hot rolling mill, in the space between the lower drive roller 4 of the driver 2 and its associated, the hot rolled steel strip 1 reeling coiler station 8, a sampling device 10 for sampling the partially rewound hot rolled steel strip 1 available. It is shown the end of the hot rolled steel strip 1, which is not yet wound on the collar 9, but still protrudes from him. From this end a piece is separated from the hot-rolled steel strip 1 by means of sampling device 10 in the illustrated moment as a sample 11, before the hot-rolled steel strip 1 is completely wound into the coil 9 in the coiling station 8.

Die Probennahme kann auch anders als in Figur 1 geschlossen gezeichnet dargestellt erfolgen - eine Auswahl anderer Varianten für Anordnung von Ende des warmgewalzten Stahlbandes und Probenahmevorrichtung ist strichliert gezeichnet in Figur 1 dargestellt. Bei diesen Varianten ist zum Zeitpunkt der Probennahme der Wickelprozess in der Haspelstation noch nicht abgeschlossen, weil der Bund noch nicht zur Entnahme aus der Haspelstation fertiggestellt ist.Sampling may also be different than in FIG. 1 shown closed drawn - a selection of other variants for arrangement of the end of the hot rolled steel strip and sampling device is drawn in dashed lines in FIG. 1 shown. In these variants, the winding process in the coiling station is not yet completed at the time of sampling, because the federal government is not yet completed for removal from the coiler station.

Während die Probennahme erfolgt, wird der bereits aufgewickelte Teil des Bundes 9 von den jeweils in einer nicht extra dargestellten schwenkbaren Schwinge einer Schwingenhaspel angeordneten Andrückrollen 12a, 12b, 12c der Haspelstation 8 gehalten; ein Aufspringen des bereits aufgewickelten Teils des Bundes 9 kann also nicht stattfinden.While the sampling takes place, the already wound part of the collar 9 is held by the pressure rollers 12a, 12b, 12c of the coiling station 8, which are each arranged in a pivotable rocker of a swinging reel not shown separately; a popping of the already wound part of the Federal 9 so can not take place.

Figur 1 zeigt auch einen weiteren Treiber 13, der ein anderes warmgewalztes Stahlband 14 in die dem weiteren Treiber 13 zugeordnete Haspelstation 15 treibt, während von Stahlband 1 die Probe 11 genommen wird. Wenn der Bund 16 in der Haspelstation 15 sich der gewünschten Endgröße nähert, kann mittels einer nicht dargestellten FIG. 1 also shows a further driver 13, which drives another hot rolled steel strip 14 into the coiling station 15 associated with the further driver 13, while the sample 11 is taken from steel strip 1. When the collar 16 in the coiler station 15 approaches the desired final size, can by means of a non-illustrated

Probennahmevorrichtung analog zur Probennahme am Bund 9 eine Probe genommen werden. Mittels der Weichen 7a, 7b kann warmgewalztes Stahlband in die Haspelstationen 8 oder 15 gelenkt werden.Sampling device analogous to sampling on the collar 9 a sample can be taken. By means of the switches 7a, 7b hot-rolled steel strip can be directed into the coiler stations 8 or 15.

Figur 2 zeigt eine zu Figur 1 weitgehend analoge Darstellung, wobei die Probennahmevorrichtung zur Probennahme von teilweise aufgewickeltem warmgewalztem Metallband zwischen einer unteren Treibrolle 4 des Treibers 2 und der dem Treiber 2 zugeordneten Haspelstation 8 angeordnet ist. FIG. 2 shows one too FIG. 1 largely analog representation, wherein the sampling device for sampling of partially wound hot rolled metal strip between a lower drive roller 4 of the driver 2 and the driver 2 associated coiling station 8 is arranged.

In Figur 1 und Figur 2 sind auch Einlaufführungen 17 schematisch dargestellt, die das Metallband zum Eintritt in die Treiber führen.In FIG. 1 and FIG. 2 Also inlet guides 17 are shown schematically, which lead the metal strip for entry into the driver.

Obwohl die Erfindung im Detail durch die bevorzugten Ausführungsbeispiele näher illustriert und beschrieben wurde, so ist die Erfindung nicht durch die offenbarten Beispiele eingeschränkt und andere Variationen können vom Fachmann hieraus abgeleitet werden, ohne den Schutzumfang der Erfindung zu verlassen.While the invention has been further illustrated and described in detail by the preferred embodiments, the invention is not limited by the disclosed examples, and other variations can be derived therefrom by those skilled in the art without departing from the scope of the invention.
