Abstract

The invention relates to a method and a direct strand reduction installation for producing a metal strip, in particular a hot-rolled steel strip consisting of a continuous cast pre-strip, on pass lines comprising blooming trains (2) and finishing trains (3). According to the invention, the changeover from the blooming train (2) into the finishing train (3) is achieved in an energy saving manner and without additional equipment. To achieve this, the cast strand in the blooming train (2), which has a direct connection to a run-out of the continuous casting installation (1), is rolled to form a pre-strip and is subsequently coiled in a winding coil box (4) and only the thermal losses of the coils are compensated in relation to the initial pass temperature, by heating the coils in a continuous furnace (7).

Description

Die Erfindung betrifft ein Verfahren und eine Gieß-Walz-Anlage zum Herstellen von Metallband, insbesondere von warmgewalztem Stahlband aus stranggegossenem Vorband in Walzlinien von Vorstraßen und Fertigstraßen. The invention relates to a method and a casting and rolling plant for producing Metal strip, in particular of hot-rolled steel strip made of continuous cast Supporting strip in rolling lines of roughing lines and finishing lines.

Aus der DE 38 40 812 C2 ist eine ISP-Dünnbrammengieß- und Walzanlage bekannt, in der die gegossenen Dünnbrammen zunächst vorverformt werden, dann in einer Coilbox gewickelt und wieder abgewickelt werden, um dann in die in räumlicher Nähe befindliche Fertigstraße eingeführt zu werden. From DE 38 40 812 C2 an ISP thin slab casting and rolling plant is known, in which the cast thin slabs are first preformed, then in one Coilbox can be wrapped and unwound again, then in close proximity existing finishing train to be introduced.

Eine ähnliche Anlage ist aus der DE 196 17 856 C1 bekannt. Solche Anlagen dienen hauptsächlich der Platzeinsparung, dem Temperaturausgleich innerhalb des Vorbandes sowie der Trennung zwischen Gießgeschwindigkeit und Walzgeschwindigkeit. A similar system is known from DE 196 17 856 C1. Such facilities serve mainly the space saving, the temperature compensation within the Supporting strip and the separation between casting speed and Rolling speed.

Zur Zeit werden in Warmflachwalzwerken die Vorstraße und die Fertigstraße immer in räumlicher Nähe gebaut. Der Temperaturverlust in der Vorstraße beträgt ca. 150 K. Um die erforderlich Eintrittstemperatur in die Fertigstraße von ca. 1100°C zu erreichen, müssen die abgeteilten Brammen in Hubbalkenöfen auf ca. 1250°C aufgeheizt werden. Dabei ist ein hoher Aufwand an Energie erforderlich, da zum einen die Heizenergie auf die Brammen übergehen muss und zum anderen die Temperaturverluste im Ofen aufgefangen werden müssen. At the moment, the roughing and finishing lines are always used in hot flat rolling mills built in close proximity. The temperature loss in the roughing street is approx. 150 K. To the required entry temperature in the finishing train of approx. 1100 ° C the divided slabs in walking beam furnaces must reach approx. 1250 ° C be heated. A high expenditure of energy is required because, on the one hand, the Heating energy must pass to the slabs and the other Temperature losses in the oven must be absorbed.

Es bestehen andere Vorschläge, die Bramme möglichst warm in die Hubbalkenöfen einzuschleusen, um die Heizenergie zum Aufheizen der Bramme weitgehend gering zu halten. Dazu werden z. B. Warmhaltegruben, Rollgänge von der Stranggießvorrichtung bis unmittelbar an die Öfen oder bei CSP-Anlagen unmittelbar aus der Stranggießvorrichtung in den Durchlaufofen eingesetzt. There are other suggestions to warm the slab as warmly as possible in the walking beam furnace infiltrate in order to keep the heating energy for heating the slab largely low to keep. For this z. B. warming pits, roller tables from the Continuous casting device right up to the furnaces or, in the case of CSP systems, directly from the Continuous casting device used in the continuous furnace.

Der Erfindung liegt die Aufgabe zugrunde, einen Wechsel von der Vorstraße in die Fertigstraße ohne großen Energieverlust und ohne zusätzliche Einrichtungen zu vollziehen. The invention has for its object a change from the Vorstraße in the Finishing line without much energy loss and without additional facilities too take place.

Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Gießstrang in einer Vorstraße, die unmittelbar an einen Auslaufrollgang der Stranggießanlage angeschlossen ist, zu Vorband gewalzt und anschließend in einer Coilbox gewickelt wird und dass lediglich Wärmeverluste des Coils gegenüber der Fertigwalz-Anstich- Temperatur durch Aufheizen des Coils in einem Coil-Durchlaufofen ausgeglichen werden. Dabei wird die Wärme des Gießstrangs ausgenutzt, die dieser ohnehin beinhaltet. Der Vorteil ist eine Energieeinsparung durch die geringere Aufheiztemperatur. The object is achieved according to the invention in that the casting strand in a roughing street that is directly connected to an exit roller table of the continuous caster is connected, rolled to support strip and then wound in a coil box and that only heat loss of the coil compared to the finish rolling tapping Temperature compensated by heating the coil in a continuous coil furnace become. The heat of the casting strand is exploited, which it is anyway includes. The advantage is an energy saving due to the lower Heating temperature.

Die räumliche Trennung von Vorstraße und Fertigstraße kann dabei dadurch außer acht gelassen werden, indem das in der Coilbox gewickelte Vorband aus dem Coil- Ofen zu einer räumlich getrennten Fertigstraße transportiert wird. Die räumliche Trennung von Vorstraße und Fertigstraße besitzt demnach nicht mehr die bisherige Bedeutung. Auch im Grenzfall keiner räumlichen Trennung kann das Verfahren angewendet werden. The spatial separation of the roughing and finishing lines can thereby be excluded be careful by pulling the opening strip wound in the coil box out of the coil Furnace is transported to a spatially separated finishing train. The spatial The separation of the roughing and finishing lines is therefore no longer the same as before Importance. Even in the borderline case of no spatial separation, the method can be applied.

Weitere Vorteile ergeben sich dadurch, dass der mit Brammen-Querschnitt gegossene Gießstrang zu einem Vorband mit Dicken zwischen 20 bis 50 mm gewalzt wird. Further advantages result from the fact that the slab cross-section cast casting strand is rolled to a preliminary strip with thicknesses between 20 to 50 mm.

Andere Merkmale können mit Vorteilen verbunden sein, indem das in der Coilbox gewickelte Vorband auf eine Temperatur knapp über 1100°C aufgeheizt wird. Other features can be associated with advantages by being in the coil box wound pre-strip is heated to a temperature just above 1100 ° C.

Eine Gieß-Walz-Anlage zur Herstellung von Metallband, insbesondere von warmgewalztem Stahlband aus stranggegossenem Vorband in Walzlinien von Vorstraßen und Fertigstraßen, ist nach anlagentechnischen Merkmalen dahingehend gestaltet, dass eine Vorstraße unmittelbar an eine Stranggießanlage angeschlossen ist, dass für das Vorband eine Aufwickel-Coilbox am Ende der Vorstraße angeordnet ist und dass Wärmeverluste des Coils innerhalb eines Coil-Transportwegs in einem Coil- Durchlaufofen ausgleichbar sind, der am Eingang der Fertigstraße angeordnet ist. Der Vorteil ist eine Energie-Einsparung durch die geringere Aufheiztemperatur des Coils. A casting and rolling plant for the production of metal strip, in particular hot-rolled steel strip from continuously cast pre-strip in the rolling lines of primary lines and finishing lines, is designed according to technical plant characteristics, that a roughing mill is directly connected to a continuous caster a roll-up coil box is arranged for the opening strip at the end of the roughing street and that heat losses of the coil within a coil transport path in a coil Continuous furnace can be compensated, which is arranged at the entrance to the finishing train. The advantage is an energy saving due to the lower heating temperature of the Coils.

In Ausgestaltung der Erfindung ist im Materialfluss hinter einer Coil-Aufgabe mit Coil- Durchlaufofen am Eingang der Fertigstraße eine Coilbox zum Abwickeln des Vorbandes angeordnet. Das Vorband geht daher in die Fertigstraße mit einer sehr genauen Fertigwalz-Anstichtemperatur hinein. In an embodiment of the invention, in the material flow behind a coil task with coil Continuous furnace at the entrance of the finishing train a coil box for unwinding the Supporting tape arranged. The opening act therefore goes into the finishing train with a very exact finish rolling piercing temperature.

Außerdem ist nach einem anderen Vorteil vorgesehen, dass am Eingang der Fertigstraße eine Zunder-Wascheinrichtung angeordnet ist. In addition, it is provided according to another advantage that the Finishing mill a scale washing device is arranged.

In der Zeichnung ist ein Ausführungsbeispiel der Gieß-Walz-Anlage zum Herstellen von Metallband, insbesondere von warmgewalztem Stahlband, dargestellt, als in einer Stranggießanlage 1 stranggegossenem Vorband, das in Walzlinien von Vorstraße 2 und Fertigstraße 3 weitergewalzt wird. Das Vorband wird in der Vorstraße 2mit Vorgerüsten 2a und 2b unter Ausnutzung der Schmelzwärme gewalzt und anschließend in einer Coilbox 4 aufgewickelt. Das Coil wird auf dem Coil-Transportweg 5 automatisch oder mittels Fahrzeugen in eine Coil-Aufgabe 6 transportiert, die nicht nur in der Nahe sein kann, sondern auch in einiger Entfernung, und durchläuft einen Coil-Durchlaufofen 7. Es findet nur ein geringer Wärmeverlust des gewickelten Vorband-Coils während des Transports auf dem Coil-Transportweg 5 statt, weil im Vergleich zu Brammen eine geringe Oberfläche beim Abstrahlen von Wärme gegeben ist. Die im Ausführungsbeispiel zugrundegelegte größere Entfernung zwischen der Stranggießanlage 1 und der Fertigstraße 3 kann ohne größeren Energieverlust zurückgelegt werden und somit kann ein sog. Warmeinsatz des Vorbandes ermöglicht werden. Beim Nachwärmen des Coils im Coil-Durchlaufofen 6 ist aufgrund der zugrundegelegten Abmessungen, z. B. eine weitere Energieeinsparung vorteilhaft, da der Wärmeverlust der Vorstraße 2 nicht mehr berücksichtigt werden muss. In the drawing, an embodiment of the casting-rolling plant for the production of metal strip, in particular hot-rolled steel strip, is shown as a continuous cast strip in a continuous casting plant 1 , which is further rolled in rolling lines from roughing train 2 and finishing train 3 . The roughing strip is rolled in roughing mill 2 with roughing stands 2 a and 2 b using the heat of fusion and then wound up in a coil box 4 . The coil is transported on the coil transport path 5 automatically or by means of vehicles into a coil task 6 , which can not only be in the vicinity, but also at a distance, and passes through a continuous coil furnace 7 . There is only a slight heat loss of the wound pre-strip coil during the transport on the coil transport path 5 because, compared to slabs, there is a small surface when heat is emitted. The larger distance between the continuous casting plant 1 and the finishing train 3 , which is the basis in the exemplary embodiment, can be covered without major loss of energy and thus a so-called warm use of the preliminary strip can be made possible. When reheating the coil in the continuous coil furnace 6 is due to the underlying dimensions, for. B. further energy savings advantageous because the heat loss of the Vorstraße 2 no longer needs to be taken into account.

Sodann wird das Vorband in einer weiteren Abwickel-Coilbox 8 abgewickelt, in einer Schopfschere 9 geschopft und über eine Zunder-Wascheinrichtung 10 in die Fertigstraße 3 eingeführt und zu Fertigband in den Fertiggerüsten 11 bis 17 fertiggewalzt. Aufgrund der Aufteilung von Vor- und Fertigstraßen an unterschiedlichen Orten ergibt sich eine Flexibilität bei Planung und Ausführung der Anlagen, insbesondere bei beengten Platzverhältnissen.
