Die vorliegende Erfindung betrifft eine Gießwalzanlage für ein Metallband, insbesondere ein Stahlband, mit einer Gie߬ einrichtung, einer Warmwalzeinrichtung und einer Kühlstrecke,The present invention relates to a cast roll plant for a metal strip, in particular a steel strip, with a casting ¬ device , a hot rolling device and a cooling section,

- wobei die Kühlstrecke der Warmwalzeinrichtung nachgeordnet ist, so dass das Metallband nach dem Warmwalzen in der Kühlstrecke mit einem Kühlmedium kühlbar ist .- Wherein the cooling section of the hot rolling device is arranged downstream, so that the metal strip after hot rolling in the cooling section with a cooling medium can be cooled.
Die vorliegende Erfindung betrifft weiterhin ein Erzeugungs¬ verfahren für ein Metallband, insbesondere ein Stahlband,The present invention furthermore relates to a production method for a metal strip, in particular a steel strip,
- wobei flüs siges Metall in einer Gießeinrichtung zu einem Metallband mit einer Anfangsdicke gegossen wird,wherein liquid metal is poured in a casting device into a metal strip having an initial thickness,
- wobei das gegossene Metallband unmittelbar nach dem Gießen mit der Anfangsdicke einer Warmwalzeinrichtung zugeführt und dort warmgewalzt wird,- wherein the cast metal strip is fed immediately after casting with the initial thickness of a hot rolling device and hot rolled there,
- wobei das warmgewalzte Metallband sodann in einer Kühlstre- cke mit einem Kühlmedium gekühlt wird.- Wherein the hot-rolled metal strip is then cooled in a cooling section with a cooling medium.
Schließlich betrifft die vorliegende Erfindung noch ein Metallband, insbesondere ein Stahlband.Finally, the present invention also relates to a metal strip, in particular a steel strip.
Gießwalzanlagen der oben stehend beschriebenen Art und die entsprechenden Erzeugungsverfahren für ein Metallband sind allgemein bekannt . Für derartige Gießwalzanlagen ist unter anderem bekannt, die Gießeinrichtung bis zur Warmwalzeinrichtung einzuhausen und mit einem Schutzgas zu fluten, so dass ein Verzundern des Metallbandes bis zur Warmwalzeinrichtung vermieden wird. Nach dem Warmwalzen verzundert das Metallband jedoch . Im Stand der Technik wird das verzunderte Metallband zunächst abgebeizt und dann einer Kaltwalzeinrichtung zugeführt oder anderweitig weiter verarbeitet . Ein Weiterverarbeiten des Me¬ tallbandes ohne vorherige Entfernung der Zunderschicht ist hingegen nicht möglich .Cast rolling mills of the type described above and the corresponding production methods for a metal strip are well known. It is known, inter alia, for such cast roll mills to embed the casting device as far as the hot rolling device and to flood it with a protective gas, so that scaling of the metal strip up to the hot rolling device is avoided. After hot rolling, however, the metal strip scales. In the prior art, the scaled metal strip is first pickled and then fed to a cold rolling device or otherwise processed. A further processing of Me ¬ tallbandes without prior removal of the scale layer, however, is not possible.
Die Aufgabe der vorliegenden Erfindung besteht darin, eine Möglichkeit zu schaffen, die Verzunderung des Metallbandes nach dem Warmwalzen zu vermeiden .The object of the present invention is to provide a way to avoid the scaling of the metal strip after hot rolling.
Die Aufgabe wird für die Gießwalzanlage dadurch gelöst , das s sie eine Einhausung aufweist, welche die Gießeinrichtung, die Warmwalzeinrichtung und die Kühlstrecke umgibt und mit einem Schutzgas flutbar ist .The object is achieved for the casting and rolling plant in that it has an enclosure which surrounds the casting device, the hot rolling device and the cooling section and can be flooded with a protective gas.
Hiermit korrespondierend wird die Aufgabe für das Erzeugungs¬ verfahren dadurch gelöst, dass das Metallband zumindest vom Austreten aus der Gießeinrichtung bis zum Austreten aus der Kühlstrecke in einer mit einem Schutzgas gefluteten Einhau- sung geführt wird.Correspondingly, the object for the generating ¬ method is achieved in that the metal strip is guided at least from the exit from the casting until it exits the cooling section in a flooded with a protective gas inlet.
Das Metallband ist dann dadurch gekennzeichnet, dass es in einer derartigen Gießwalzanlage erzeugt wurde, wobei die Gießwalzanlage während der Erzeugung des Metallbandes gemäß einem derartigen Erzeugungsverfahren betrieben wurde .The metal strip is then characterized in that it was produced in such a cast rolling mill, wherein the casting rolling mill was operated during the production of the metal strip according to such a production method.
Als Schutzgas kommen insbesondere zerstäubtes Wasser, Stick¬ stoff, Argon oder eine Kombination dieser Stoffe in Frage . Gegebenenfalls kann dabei dem Schutzgas ein Sauerstoffzehren- der Zusatzstoff beigemischt werden . Beispiele derartiger Zu¬ satz stoffe sind Kohlenmonoxid und manche Salze . Salze müssen dabei selbstverständlich in pulverisierter Form beigemischt werden .As a shielding gas are particularly atomized water, stick ¬ material, argon, or a combination of these substances in question. If appropriate, an oxygen-consuming additive can be admixed with the protective gas. Examples of such materials are carbon monoxide to ¬ rate and some salts. Of course, salts have to be mixed in powdered form.
Vorzugsweise ist die Gießeinrichtung derart ausgebildet, dass das Metallband von ihr mit einer Anfangsdicke erzeugbar ist , die maximal 10 mm beträgt . Wenn dabei die Gießeinrichtung als Zweirollen-Gießeinrichtung ausgebildet ist, kann das gegossene Metallband eine besonders geringe Anfangsdicke von z . B . nur ein bis zwei Millimetern aufweisen .Preferably, the casting device is designed such that the metal strip can be produced by it with an initial thickness which is a maximum of 10 mm. If doing the casting device as Two-roller casting device is formed, the cast metal strip can be a particularly small initial thickness of z. B. have only one to two millimeters.
Auf Grund der geringen Anfangsdicke des Metallbandes ist es völlig ausreichend, wenn die Warmwalzeinrichtung maximal zwei Walzgerüste aufweist . Oftmals reicht sogar nur ein einziges Walzgerüst aus .Due to the small initial thickness of the metal strip, it is quite sufficient if the hot rolling device has a maximum of two stands. Often even only a single rolling stand is sufficient.
Die Kühlstrecke weist vorzugsweise eine Einspeiseeinrichtung zum Einspeisen eines der Zunderbildung entgegen wirkenden Zusatz stoffs in das Kühlmedium auf . Denn dann ist die Gefahr einer Zunderbildung noch weiter verringert .The cooling section preferably has a feed device for feeding a tinder formation counteracting additive substance in the cooling medium. Because then the danger of a scale formation is reduced even further.
In der Regel ist der Kühlstrecke eine Haspeleinrichtung nachgeordnet . Diese weist zumeist mindestens einen Haspel und ei¬ ne Schereinrichtung auf .As a rule, the cooling section is followed by a reel device. This usually has at least one reel and egg ¬ ne shear device.
Wenn das Metallband in die Haspeleinrichtung einläuft, weist es in aller Regel bereits relativ niedrige Temperaturen auf . Die Haspeleinrichtung kann daher außerhalb der Einhausung angeordnet sein .When the metal strip enters the coiling device, it usually already has relatively low temperatures. The reel device can therefore be arranged outside the housing.
Wenn der Kühlstrecke eine Kaltwalzeinrichtung nachgeordnet ist, arbeitet die Gießwalzanlage besonders effektiv, da so¬ fort und unmittelbar nach dem Gießen des Bandes dieses zu¬ nächst warmgewalzt und unmittelbar danach auch kaltgewalzt werden kann . Soweit dabei die Gießwalzanlage auch die Has¬ peleinrichtung aufweist, ist vorzugsweise die Kaltwalzein- richtung zwischen der Kühlstrecke und der Haspeleinrichtung angeordnet .If the cooling section is followed by a cold rolling device, the cast rolling mill works particularly effectively, since so ¬ fort and immediately after the casting of the strip this can be hot rolled to ¬ next and cold rolled immediately thereafter. Insofar as the casting-rolling plant having the hat ¬ peleinrichtung is preferably the Kaltwalzein- direction between the cooling line and the coiling device disposed.
Wenn die Kaltwalzeinrichtung vorhanden ist, ist sie vorzugsweise innerhalb der Einhausung angeordnet . Denn dann wird ei- ne Zunderbildung vor dem Kaltwalzen besonders zuverläs sig vermieden . Analog zur Warmwalzeinrichtung ist es auch bezüglich der Kaltwalzeinrichtung in der Regel völlig ausreichend, wenn diese zwei Walzgerüste aufweist . Oftmals ist sogar ein einzi¬ ges Walzgerüst ausreichend .If the cold rolling device is present, it is preferably located within the enclosure. Because then a calendering before cold rolling is particularly reli sig avoided. Analogous to the hot rolling device, it is also generally sufficient with respect to the cold rolling device if it has two rolling stands. Often one only peo ¬ ges roll stand is even sufficient.
Aufgrund der erfindungsgemäßen Ausgestaltung der Gießwalzanlage ist es möglich, dass zwischen der Warmwalzeinrichtung und der Kaltwalzeinrichtung keine Entzunderungseinrichtung angeordnet ist . Das Metallband wird also zwischen dem Warm- walzen und dem Kaltwalzen nicht entzundert .Due to the inventive design of the casting rolling mill, it is possible that no descaling device is arranged between the hot rolling device and the cold rolling device. The metal strip is thus not descaled between hot rolling and cold rolling.
Weitere Vorteile und Einzelheiten ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels in Verbindung mit der Zeichnung . Dabei zeigt die einzigeFurther advantages and details will become apparent from the following description of an embodiment in conjunction with the drawings. The only one shows
FIG eine Gießwalzanlage .FIG a cast rolling mill.
Gemäß der FIG weist eine Gießwalzanlage in ihrer Minimalkon¬ figuration eine Gießeinrichtung 1 , eine Warmwalzeinrichtung 2 und eine Kühlstrecke 3 auf .

The casting device 1, the warm ¬ roller device 2 and the cooling section 3 are surrounded by a housing 4.
Mittels einer üblichen Zuführeinrichtung 5, z . B . einem Tun- dish mit einem daran angeordneten Tauchrohr, wird der Gießeinrichtung 1 flüs siges Metall 6 ( z . B . flüssiger Stahl 6 ) zugeführt und von der Gießeinrichtung 1 zu einem Metallband 7 gegossen . Gemäß der FIG ist die Gießeinrichtung 1 dabei (beispielhaft ) als Zweirollen-Gießeinrichtung 1 ausgebildet . Mit ihr ist daher ein sehr dünnes Metallband 7 gießbar, das eine Anfangsdicke dl von nur ca . 1 bis 10 mm aufweist, beispiels¬ weise von 1 , 5 bis 3 mm .By means of a conventional feeder 5, z. B. a tunable with a dip tube arranged thereon, the casting device 1 is supplied with liquid metal 6 (for example liquid steel 6) and cast from the casting device 1 into a metal strip 7. According to FIG. 1, the casting device 1 is designed (by way of example) as a two-roller casting device 1. With her, therefore, a very thin metal strip 7 is pourable, which has an initial thickness dl of only approx. 1 to 10 mm, for example ¬ from 1, 5 to 3 mm.
Das Metallband 7 wird unmittelbar nach dem Gießen, also ohne vorherige Pufferung oder sonstige Zwischenlagerung, überThe metal strip 7 is immediately after casting, so without previous buffering or other temporary storage on
Treibrollen 8 der Warmwalzeinrichtung 2 zugeführt . Die Warmwalzeinrichtung 2 ist daher der Gießeinrichtung 1 nachgeord- net . In der Warmwalzeinrichtung 2 wird das Metallband 7 warmgewalzt, so dass es mit einer Zwischendicke d2 aus der Warm¬ walzeinrichtung 2 ausläuft . Das Walzen in der Warmwalzeinrichtung 2 erfolgt dabei, wie aus der FIG ersichtlich ist, bei einer Temperatur T oberhalb von 723 °C .Driven rollers 8 of the hot rolling device 2 supplied. The hot rolling device 2 is therefore the casting device 1 nachgeord- net. In the hot rolling device 2, the metal strip 7 is hot rolled, so that it expires with an intermediate thickness d 2 from the warm ¬ roller device 2. The rolling in the hot rolling device 2 takes place, as can be seen from the FIG, at a temperature T above 723 ° C.
Gemäß der FIG weist die Warmwalzeinrichtung 2 ein einziges Walzgerüst auf . Sie könnte aber auch zwei Walzgerüste aufwei¬ sen .As shown in the FIGURE, the hot rolling device 2 has a single roll stand. But you could also aufwei ¬ sen two rolling stands.
Sodann wird das warmgewalzte Metallband 7 der Kühlstrecke 3 zugeführt . Die Kühlstrecke 3 ist also der Warmwalzeinrichtung 2 nachgeordnet . In der Kühlstrecke 3 wird das Metallband 7 nach dem Warmwalzen mit einem Kühlmedium 8 gekühlt . Das Kühl- medium 8 ist dabei in der Regel Was ser, vorzugsweise erwärm¬ tes Wasser . Gegebenenfalls kann ihm, wie in der FIG angedeu¬ tet ist, ein Zusatzstoff beigemischt werden, welcher der Zun¬ derbildung entgegenwirkt . Hierzu weist die Kühlstrecke 3 eine entsprechende Einspeiseeinrichtung 9 auf .Then, the hot-rolled metal strip 7 of the cooling section 3 is supplied. The cooling section 3 is thus downstream of the hot rolling device 2. In the cooling section 3, the metal strip 7 is cooled after hot rolling with a cooling medium 8. The cooling medium 8 is usually what ser, preferably Warming ¬ tes water. Optionally, it may as tet angedeu ¬ in the FIG, an additive are added, wherein the Zun ¬ derbildung counteracts. For this purpose, the cooling section 3 has a corresponding feed device 9.
Gemäß der FIG ist die gesamte Einhausung 4 mit einem Schutzgas geflutet . Das Metallband 7 ist somit vom Austreten aus der Gießeinrichtung 1 an bis zum Austreten aus der Kühlstrecke 3 in der Einhausung 4 geführt, welche mit dem Schutzgas geflutet ist . Als Schutzgas kommen insbesondere zerstäubtesAccording to the FIG the entire enclosure 4 is flooded with a protective gas. The metal strip 7 is thus guided from the exit from the casting device 1 until it leaves the cooling section 3 in the housing 4, which is flooded with the protective gas. As a protective gas come in particular atomized
Wasser, Stickstoff, Argon oder eine Kombination dieser Stoffe in Frage . Weiterhin kann dem Schutzgas ein Sauerstoffzehrender Zusatzstoff beigemischt werden . Beispiele derartiger Zu¬ satz stoffe sind Kohlenmonoxid und geeignete, Sauerstoffzeh- rende pulverisierte Salze . Auch hier ist wieder eine Kombina¬ tion dieser Stoffe möglich .Water, nitrogen, argon or a combination of these substances in question. Furthermore, the inert gas can be admixed with an oxygen-consuming additive. Examples of such materials are set to ¬ carbon monoxide and appropriate, Sauerstoffzeh--saving powdered salts. Here again a combina ¬ tion of these substances possible.
Gemäß der FIG kann die erfindungsgemäße Gießwalzanlage weite¬ re Einrichtungen 10 , 11 aufweisen, nämlich eine Haspelein- richtung 10 und eine Kaltwalzeinrichtung 11. Beide Einrichtungen 10 , 11 sind der Kühlstrecke 3 nachgeordnet . Falls bei¬ de Einrichtungen 10 , 11 vorhanden sind, ist weiterhin die Kaltwalzeinrichtung 11 zwischen der Kühlstrecke 3 und der Haspeleinrichtung 10 angeordnet .According to the FIG cast casting plant according to the invention further ¬ devices 10, 11, namely a reel device 10 and a cold rolling device 11. Both devices 10, 11 are downstream of the cooling section 3. If there are any in ¬ de devices 10, 11, continues to be the Cold rolling device 11 is disposed between the cooling section 3 and the reel device 10.
Die Haspeleinrichtung 10 weist mindestens einen Haspel 12 auf . Gemäß der FIG weist sie sogar zwei Haspel 12 auf . Wei¬ terhin weist sie eine Schereinrichtung 13 auf . Die Haspeleinrichtung 10 ist vorzugsweise außerhalb der Einhausung 4 ange¬ ordnet .The reel device 10 has at least one reel 12. According to the FIG it even has two reel 12. Wei ¬ terhin it has a shearing means. 13 The reel device 10 is preferably located outside the housing 4 is arranged ¬.
Die Kaltwalzeinrichtung 11 ist nach Bedarf ausgebildet . Sie ist vorzugsweise innerhalb der Einhausung 4 angeordnet . Gemäß der FIG weist sie - ebenso wie die Warmwalzeinrichtung 2 - nur ein einziges Walzgerüst auf . Sie könnte aber z . B . auch zwei Walzgerüste aufweisen . In der Kaltwalzeinrichtung 11 wird das Metallband 7 auf eine Enddicke d3 heruntergewalzt .The cold rolling device 11 is formed as needed. It is preferably arranged within the housing 4. According to the FIG shows - as well as the hot rolling device 2 - only a single stand on. But you could z. B. also have two rolling stands. In the cold rolling device 11, the metal strip 7 is rolled down to a final thickness d3.
Auf Grund der Anordnung der Kaltwalzeinrichtung 11 innerhalb der Einhausung 4 ist es nicht erforderlich, dass zwischen der Warmwalzeinrichtung 2 und der Kaltwalzeinrichtung 11 eine Entzunderungseinrichtung angeordnet ist . Diese kann daher entfallen . Denn zwischen dem Warmwalzen und dem Kaltwalzen muss das Metallband 7 nicht entzundert werden .Due to the arrangement of the cold rolling device 11 within the housing 4, it is not necessary that a descaling device is arranged between the hot rolling device 2 and the cold rolling device 11. This can therefore be omitted. Because between the hot rolling and the cold rolling the metal strip 7 does not have to be descaled.
Mittels der erfindungsgemäßen Gießwalzanlage ist somit auf einfache und insbesondere kostengünstige Weise ein qualitativ hochwertiges Metallband 7 erzeugbar . By means of the cast rolling mill according to the invention, a high-quality metal strip 7 can thus be produced in a simple and, in particular, cost-effective manner.
