Description

Ofenklappen für WickelöfenOven flaps for winding ovens
Die Erfindung betrifft Ofenklappen für insbesondere in Steckelwalzwerken einsetzbare Wickelöfen, in denen ein warmgewalztes Band im Hin- und Hertransport jeweils reversierend auf einer Ofentrommel im Ofeninnern auf- und abwik- kelt und gegebenenfalls erwärmt wird, umfassend auf den beweglichen Ofenklappen des Wickelofens montierte Leittische zum Einfädeln und/oder Führen des Walzbandes.The invention relates to furnace flaps for winding furnaces which can be used, in particular, in Steckel rolling mills, in which a hot-rolled strip is reversibly wound up and down and possibly heated on the inside of a furnace during transport back and forth, including guide tables for threading mounted on the movable furnace flaps of the winding furnace and / or guiding the rolled strip.
Wegen der außerordentlich hohen thermischen Belastung der eingesetzten Steckelöfen, wurden deren verstellbare Klappen mit pneumatisch betätigten Antrieben versehen. Dabei war es üblich, diese Klappen direkt am Ofen zu be- festigen. Dies erschwert jedoch den Wechsel der Leittische, die auf den Klappen montiert sind. Für diesen Vorgang mußten nämlich die Öfen vollständig abgekühlt werden. Dies erfordert jedoch einen schwierigen und lang dauernden Arbeitsprozeß, weil sehr lange Kühlzeiten zugleich mit äußerst schwierigen Arbeitsbedingungen zusammenfallen. Diese Umstände ergeben hohe Arbeits- kosten und relativ lange Stillstandzeiten der entsprechenden Anlage.Due to the extraordinarily high thermal load on the plug-in furnaces used, their adjustable flaps were equipped with pneumatically operated drives. It was customary to attach these flaps directly to the furnace. However, this makes it difficult to change the control tables that are mounted on the flaps. This is because the ovens had to be cooled completely for this process. However, this requires a difficult and long-lasting working process because very long cooling times coincide with extremely difficult working conditions. These circumstances result in high labor costs and relatively long downtimes of the corresponding system.
Zur Abhilfe wurde mit der EP 0 936 276 A2 ein Vorschlag erarbeitet, um Wik- kelöfen insbesondere zur Verwendung in Steckelwalzwerkeri angesichts der erkannten Schwierigkeiten zu verbessern.To remedy this, a proposal was developed with EP 0 936 276 A2 in order to improve winding furnaces, in particular for use in Steckel rolling mills, in view of the difficulties identified.
Der aus dem vorgenannten Dokument bekannte Wickelofen, umfasst einen oberen Gehäuseteil und einen unteren Gehäuseteil, die miteinander fest verbindbar sind, sowie eine Ofentrommel im Gehäuse mit Mitteln zur Aufnahme eines Walzbandes. Das Gehäuse besitzt einen vom unteren Gehäuse separa- ten Bodenteil, wobei das Boden-Gehäuseteil relativ zum unteren Gehäuse beweglich ist. Infolgedessen kann der Boden-Gehäuseteil bewegt werden, selbst wenn das Innere des Ofens noch heiß ist. Das bodenseitige Gehäuseteil ist so ausgebildet und angeordnet, dass es zusammen mit beweglichen Rollgangsrollen bewegt bzw. ausgebaut werden kann. Im Ergebnis wird dadurch die Wechselzeit von beispielsweise bisher 30 Stunden auf etwa 5 Stunden abgekürzt.The winding furnace known from the aforementioned document comprises an upper housing part and a lower housing part, which can be firmly connected to one another, as well as an oven drum in the housing with means for receiving a rolled strip. The housing has a bottom part separate from the lower housing, the bottom housing part being movable relative to the lower housing. As a result, the bottom case part can be moved even when the inside of the oven is still hot. The bottom housing part is designed and arranged so that it can be moved or removed together with movable roller table rollers. As a result, the changeover time is shortened from, for example, 30 hours to about 5 hours.
Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine verbesserte Bauart eines Wickelofens und insbesondere dessen Ofenklappe anzugeben, durch welche kürzere Rüstzeiten ermöglicht werden.Starting from the aforementioned prior art, the invention is based on the object of specifying an improved design of a winding furnace and in particular its furnace flap, by means of which shorter set-up times are made possible.
Diese Aufgabe wird bei Ofenklappen der im Oberbegriff von Anspruch 1 genannten Art mit der Erfindung dadurch gelöst, dass die Ofenklappen und der zugeordnete Wickelofen separate Baukörper sind, dass die Ofenklappen auf einem unterhalb des Wickelofens befindlichen Teil eines Rollgangsrahmens angeordnet sind und dass jede Ofenklappe in wenigstens zwei zu einander klappbare Elemente aufgeteilt ist und beide Klappelemente über eine Klappenlagerung verbunden sind und schwenkbar angebracht sind.This object is achieved in furnace flaps of the type mentioned in the preamble of claim 1 with the invention in that the furnace flaps and the associated winding furnace are separate structures, that the furnace flaps are arranged on a part of a roller table frame located below the winding furnace, and that each furnace flap is in at least two foldable elements are divided and both fold elements are connected via a flap bearing and are pivotally attached.
In Ausgestaltung der Erfindung ist vorgesehen, dass der Rollgangsrahmen auf Führungsschienen mit der Ofenklappe aus dem Strahlungsbereich des Wickelofens bewegbar ist.In an embodiment of the invention it is provided that the roller table frame can be moved on guide rails with the furnace flap out of the radiation area of the winding furnace.
Mit großem Vorteil ermöglicht es die Befestigung der Ofenklappen auf dem darunter liegenden, verschiebbaren Rollgang, die Ofenklappen zwecks Wartung aus dem Strahlungsbereich des Ofens heraus zu fahren. Hierbei können dann die Ofentische und die Klappen problemlos gewartet werden. Dabei kann auch durch den Einsatz von Hydraulik-Zylindern die Bedienbarkeit der Klappen und ihrer Bewegungsorgane erleichtert werden. Eine Ausgestaltung der Vorrichtung nach der Erfindung sieht weiter vor, dass die Klappenlagerung auf dem Rollgangsrahmen antriebs- und bedienungsseitig auf wenigstens einer Konsole montiert ist.It is a great advantage that the furnace flaps can be attached to the sliding roller table underneath, so that the furnace flaps can be moved out of the radiation area of the furnace for maintenance. The oven tables and flaps can then be easily serviced. The operation of the flaps and their movement elements can also be made easier by the use of hydraulic cylinders. An embodiment of the device according to the invention further provides that the flap bearing is mounted on the roller table frame on the drive and operator side on at least one console.
Um dabei eine exakte Position der Klappenlagerung unter dem Ofen zu ge- währleisten, wird der bewegliche Teil des Rollgangsrahmens beim Wiedereinsetzen auf einstellbare Auflagepunkte geschoben. Die genaue Positionierung in Walzrichtung kann dabei durch eine Führung am Auflagepunkt erreicht werden.In order to ensure an exact position of the flap bearing under the oven, the movable part of the roller table frame is pushed onto adjustable support points when it is reinserted. The exact positioning in the rolling direction can be achieved by a guide at the point of contact.
Und um die entstehenden Kräfte bei der Bandbewegung aufzunehmen, wird der Rollgangsrahmen erfindungsgemäß durch Klemmzylinder arretiert.And in order to absorb the forces arising during the belt movement, the roller table frame is locked according to the invention by clamping cylinders.
Weitere Ausgestaltungen sehen vor, dass den schwenkbaren Klappenelementen der Ofenklappe mindestens jeweils ein vorzugsweise auf der Bedienungsseite angeordneter Hydraulik-Zylinder zugeordnet ist.Further configurations provide that the pivotable flap elements of the furnace flap are each assigned at least one hydraulic cylinder, which is preferably arranged on the operating side.
Und schließlich ist die erfindungsgemäße Ausgestaltung der Ofenklappe dadurch gekennzeichnet, dass sie auf der Konsole höheneinstellbar angeordnet ist.And finally, the design of the furnace flap according to the invention is characterized in that it is arranged on the console so that it can be adjusted in height.
Weitere Einzelheiten, Merkmale und Vorteile der Erfindung ergeben sich aus der nachstehenden Erläuterung eines in den Zeichnungen schematisch dargestellten Ausführungsbeispieles.Further details, features and advantages of the invention result from the following explanation of an exemplary embodiment shown schematically in the drawings.

The front flap part 2 'is draulic cylinder 3 'raised obliquely to the front, whereas the rear flap part 2 "still remains in the horizontal position. The two flap parts 2', 2" are connected and supported together at one pivot point with the flap bearing 7. The hydraulic flap 3 "is assigned to the rear flap area 2" for pivoting. The flap bearing 7 is in turn mounted on the roller table frame part 4 'on the drive and operating side (the operating side is provided to the left of the plane xx in FIG. 4) on at least one bracket 8, 8'.
Der Teil 4' des Rollgangsrahmens 4 ist mittels der Fahrrollen 14 und mittels ei- nes oder mehrerer Hydraulik-Zylinder auf Schienen 5, 5' zur Seite aus dem Rollgangsrahmen 4 verschiebbar und ist aus dem Strahlungsbereich des Wik- kelofens 1 bewegbar , wie dies aus Figur 4 erkennbar ist. Mit der Ziffer 6 sind die aufliegenden Leittische bezeichnet. Die Figuren 1 bis 4 zeigen die im Inneren des Wickelofens 1 angeordnete, motorisch antreibbare Ofentrommel 12 mit ihrer Haspel-Lagerung 13, 13'.The part 4 'of the roller table frame 4 can be displaced to the side out of the roller table frame 4 by means of the driving rollers 14 and by means of one or more hydraulic cylinders on rails 5, 5' and can be moved out of the radiation area of the winding furnace 1, as shown in FIG Figure 4 can be seen.
