Description
Die Erfindung betrifft eine Walzstraße mit einer Warmwalzgruppe, dieser vorgeordneten Öfen und mit mindestens zwei Stranggießmaschinen sowie Trennscheren vor und gegebenenfalls hinter den Öfen.The invention relates to a rolling mill with a hot rolling group, of these upstream furnaces and with at least two continuous casting machines as well as shears in front of and possibly behind the ovens.
In derartigen Walzstraßen ist die Länge der Öfen so bemessen, daß diese Vorbänder aufzunehmen vermögen, welche im wesentlichen der Länge von jeweils zu bildenden Coils entspricht. Im allgemeinen ist die erste Stranggießmaschine mit dem dazugehörigen Ofen in Linie mit der Warmwalzgruppe und die zweite Stranggießmaschinen/Ofengruppe parallel zu dieser verschoben angeordnet. Über Fährwagen in den zweiten Ofen bzw. am Ende dieser ansonsten stationären Öfen kann das Vorhand aus der Gieß- und Ofenlinie des zweiten Stranges in die Walzlinie verschoben werden. Hier muß jeweils, wenn ein Vorband einen der Öfen verlassen hat, ein neues Vorband aus dem anderen Ofen in die Warmwalzgruppe zum Anstich eingefädelt werden. Der Einfädelvorgang stellt eine Störung des stationären Gieß-Walz-Prozesses dar und erhöht das Risiko von Ausfallzeiten in Folge von Betriebsstörungen. Außerdem kommt es verstärkt zu Schrottanfall am jeweiligen Bandanfang.In such rolling mills the length of the furnaces is such that are able to accommodate these opening tapes, which are essentially the Corresponds to the length of each coil to be formed. Generally is the first continuous casting machine with the associated furnace in line with the hot rolling group and the second continuous casting machine / furnace group arranged parallel to this shifted. Via ferry cars in the second oven or at the end of these otherwise stationary ovens the forehand from the casting and furnace line of the second strand into the Rolling line to be shifted. Here each time if a supporting act one of the ovens has left, a new supporting strip from the other oven be threaded into the hot rolling group for tapping. The threading process represents a disturbance of the stationary casting-rolling process and increases the risk of downtime due to downtime. In addition, there is an increased amount of scrap on the respective Band start.
Es wurde auch schon vorgeschlagen, den Vorbandanfang mit dem Schwanzende des vorhergehenden Vorbandes zu verschweißen, so daß im Anschluß daran gewalzt werden kann. Dazu müssen jedoch kostenaufwendige Verbindungsvorrichtungen installiert werden. Zum Verbinden der Vorbänder werden große Energiemengen benötigt. It has also been suggested that the opening act begin with To weld the tail end of the previous opening strip so that can then be rolled. However, this must be costly Connection devices are installed. To connect large amounts of energy are required.
Der Erfindung liegt die Aufgabe zugrunde, eine Walzstraße vorzuschlagen, bei der sich stets in kurzen Zeitabständen wiederholende Einfädelvorgänge vermieden werden, die ohne sich in kurzen Abständen stets wiederholende energieaufwendige Verbindungsvorgänge auskommt und mit der annähernd endlos gewalzt werden kann.The invention has for its object to propose a rolling mill, which is always repeating at short intervals Threading processes can be avoided without moving in short intervals repetitive, energy-intensive connection processes and with which you can roll almost endlessly.
Dazu wird vorgeschlagen, daß jeder Stranggießmaschine ein Ofen großer Länge zugeordnet ist, daß die Öfen quer verschiebbar ausgebildet sind und aus den Strangießlinien in die von den Stranggießlinien in ihrer Lage abweichende gemeinsame Walzlinie verfahrbar sind und daß die Öfen in Längsrichtung in Segmente unterteilt sind, wobei die Segmente einzeln und unabhängig voneinander quer verschiebbar sind.For this purpose, it is proposed that each continuous casting machine have an oven long length is assigned that the furnaces are designed to be transversely displaceable and from the continuous casting lines to those of the continuous casting lines in their position deviating common rolling line can be moved and that the furnaces are longitudinally divided into segments, wherein the segments can be moved individually and independently are.
Der jeweilige Ofen großer Länge kann Vorband in Längen aufnehmen, die der Länge mehrerer fertig gewalzter Coils entspricht, so daß nach Überführen des Vorbandes aus der Gießlinie in die Walzlinie annähernd endlos gewalzt werden kann. Die quer verschiebbaren Segmente erlauben, daß nachdem das Vorband Teilbereiche des Ofens in Richtung der Warmwalzgruppe verlassen hat, die Segmente wieder in die Gießlinie zurückgeschoben werden können, so daß die kontinuierlich arbeitenden Gießmaschinen nicht gestoppt werden brauchen.The respective furnace of great length can accommodate pre-strip in lengths, which corresponds to the length of several rolled coils, so that after transfer of the pre-strip from the casting line to the rolling line can be rolled almost endlessly. The cross slide Segments allow parts of the furnace to be moved after the opening in the direction of the hot rolling group, the segments again can be pushed back into the casting line, so that the continuously working casting machines do not need to be stopped.
Die Segmente der Öfen können gleiche bzw. unterschiedliche Längen aufweisen, wobei die unterschiedlichen Längen so bemessen werden sollten, daß sich die Segmente z.B. beim Einsatz von zwei Gießmaschinen bedingt durch die ungefähr mit doppelter Gießgeschwindigkeit arbeitenden Vorschubvorrichtungen in ihrer Länge zur Warmwalzgruppe hin jeweils verdoppeln. Beim Einsatz von drei Gießlinien würde die Geschwindigkeit der Vorschubvorrichtung ungefähr der dreifachen Gießgeschwindigkeit entsprechen, so daß die Längen der Segmente sich von Segment zu Segment verdreifachen könnten. The segments of the ovens can be the same or different lengths have, the different lengths are dimensioned in this way should that the segments e.g. when using two casting machines due to the approximately double casting speed working feeders in their length to the hot rolling group double each time. If three casting lines were used, the Feeder speed approximately three times Casting speed correspond so that the lengths of the segments themselves could triple from segment to segment.
Von Vorteil ist, wenn das jeweils der Gießmaschine zugeordnete Segment der Öfen stationär ist. Dieses Ofensegment kann, nachdem der Schnitt des Vorbandes mittels der Trennschere erfolgt ist, durch die Vorschubvorrichtung schnell freigemacht werden, so daß die stationären Segmente, während sich die verschiebbaren Segmente in der Walzlinie befinden, als Puffer verwendet werden können. Eine entsprechende Anwendung ist auch für das stationäre Ofensegment vor der Warmwalzgruppe vorgesehen.It is advantageous if that which is assigned to the casting machine Segment of the furnaces is stationary. This furnace segment can, after the pre-strip has been cut by means of the cutting scissors the feed device are quickly cleared so that the stationary segments, while the sliding segments in the rolling line, can be used as buffers. A corresponding application is also available for the stationary furnace segment the hot rolling group.
