Description

GEBIET DER ERFINDUNGFIELD OF THE INVENTION

Die Erfindung betrifft einen Wickelofen, insbesondere einen Wickelofen für Steckelwalzwerke, in dem ein warmgewalztes Band im Hin- und Hertransport jeweils reversierend auf einer Ofentrommel im Ofeninneren auf- und abgewickelt und gegebenenfalls erwärmt werden kann, umfassend weiters

  • ein Gehäuse des Wickelofens mit einer Ofenöffnung für das zu wickelnde Band,
  • eine erste bewegliche Ofenklappe zum zumindest teilweisen Verschließen der Ofenöffnung,
  • eine zur oder von der Ofentrommel bewegliche Rolle zum Befestigen des aufgewickelten Bandendes.
The invention relates to a winding furnace, in particular a winding furnace for Steckel rolling mills, in which a hot-rolled strip in the forward and Hertransport each reversing on a furnace drum inside the furnace up and unwound and optionally heated, further comprising
  • a housing of the winding furnace with a furnace opening for the belt to be wound,
  • a first movable oven door for at least partially closing the oven opening,
  • a movable to or from the oven drum roller for securing the wound tape end.

Aufgrund dieser beweglichen Rolle ist es möglich, das Bandende innerhalb des Wickelofens am Wickel, der auch als Bund bezeichnet wird, anzudrücken und damit seine Position festzulegen, um es beim Abwickeln des Bandes wieder gezielt aus dem Wickelofen führen zu können.Because of this movable role, it is possible to press the end of the tape inside the winding furnace on the winding, which is also referred to as a bunch, and thus determine its position in order to again lead it out of the winding furnace when unwinding the tape.

STAND DER TECHNIKSTATE OF THE ART

Es gibt Fälle, in denen es wünschenswert ist, das komplette Band ganz in den Wickelofen einzuziehen. Ein solcher Fall liegt vor, wenn der Betrieb auf Grund einer Störung während des Walzens eines Metallbandes unterbrochen werden muss. Ein anderer Fall liegt vor, wenn bei bestimmten Metallgüten eine Walzpause erforderlich ist, um die gewünschten metallurgischen Eigenschaften einzustellen. In solchen Fällen wird durch das Aufwickeln des gesamten Bandes ein unzulässiges Abkühlen des Bandendes vermieden.There are cases where it is desirable to pull the entire tape completely into the winding furnace. Such a case exists when operation must be interrupted due to a disturbance during rolling of a metal strip. Another case is when certain metal grades require a rolling break to set the desired metallurgical properties. In such cases, unwinding of the entire band prevents unacceptable cooling of the band end.

Vor allem bei den letzten Walzstichen, wo das Band schon relativ dünn ist, kann das Bandende, falls es außerhalb des Wickelofens geblieben ist, um bis zu 150°C und mehr kälter sein als die Bandmitte. Dadurch ergeben sich an den Bandenden bei den folgenden letzten Stichen Walzkräfte, die doppelt so hoch oder noch höher sein können als in der Bandmitte. Durch die tiefen Temperaturen an den Bandenden können dort die gewünschten mechanischen Eigenschaften nicht mehr erreicht werden, es tritt die für Steckelwalzwerke typische hohe Verschnittrate auf. Die hohen Kräfte an den Bandenden können dazu führen, dass man in der Stichplangestaltung eingeschränkt ist und im äußersten Fall bestimmte Produkte nicht mehr herstellen kann, etwa, wenn durch die hohen erforderlichen Walzkräfte zusätzliche Walzstiche erforderlich sind, diese jedoch ein Erreichen der notwendigen Endwalztemperaturen unmöglich macht.Especially in the last rolling passes, where the band is already relatively thin, the end of the tape, if it is left outside the winding furnace, can be up to 150 ° C and more colder than the center of the band. This results in the band ends at the following last stitch rolling forces that can be twice as high or even higher than in the middle of the band. Due to the low temperatures at the ends of the strip, the desired mechanical properties can no longer be achieved there; the high cut rate typical for Steckel mills occurs. The high forces at the belt ends can lead to limited in the Stichplangestaltung and in the extreme case, certain products can no longer produce, such as when the high rolling forces required additional rolling passes are required, but this makes it impossible to achieve the necessary Endwalztemperaturen ,

Bereits die DE 10 2006 037 962 A1 zeigt eine entsprechende mögliche Ausführungsform eines Wickelofens, die ein vollständiges Einziehen des Bandes in den Wickelofen ermöglicht. Im Inneren des Wickelofens ist eine sogenannte Ofenrolle vorgesehen, welche das Aufspringen des Wickels verhindert. Sie ist - von der Drehachse der Ofentrommel her gesehen - vom festen Gehäuse des Wickelofens umgeben und wird mittels außerhalb des Wickelofens angebrachter Hebel auf die Windungen des Bandes gedrückt. Die Öffnung des Wickelofens kann durch eine Ofenklappe, bestehend aus zwei schwenkbar miteinander verbundenen Klappenelementen, verschlossen werden, wobei die Ofenklappe an einem unter dem Wickelofen angeordneten Rollgangrahmen befestigt ist.Already the DE 10 2006 037 962 A1 shows a corresponding possible embodiment of a winding furnace, which allows a complete retraction of the tape in the winding furnace. Inside the winding furnace, a so-called oven roll is provided, which prevents the popping of the roll. It is - seen from the axis of rotation of the kiln drum - surrounded by the fixed housing of the winding furnace and is pressed by means mounted outside of the winding furnace lever on the turns of the tape. The opening of the winding furnace can be closed by a furnace flap, consisting of two pivotally interconnected flap elements, wherein the furnace flap is attached to a roll-up frame arranged under the winding furnace.

Nachteilig ist die technisch aufwändige Konstruktion einer Ofenklappe aus zwei zueinander verschwenkbaren Klappenelementen und der zusätzlichen Hebelkonstruktion für die Rolle zum Befestigen des aufgewickelten Bandendes.A disadvantage is the technically complex construction of a furnace flap of two mutually pivotable Flap elements and the additional lever construction for the role to attach the wound tape end.

Es ist daher eine Aufgabe der Erfindung, die Konstruktion der Ofenklappe zu vereinfachen.It is therefore an object of the invention to simplify the construction of the oven door.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Bei einem Wickelofen nach dem Oberbegriff des Anspruchs 1 ist daher vorgesehen, dass die erste Ofenklappe starr und um einer erste Drehachse drehbar ausgeführt ist, und die drehbare Rolle gemeinsam mit ihrer Aufhängung eine zweite Ofenklappe bildet, die starr und um eine zweite Drehachse beweglich ausgebildet ist, und das mit erster und zweiter Ofenklappe die Ofenöffnung (jene für den Transport des Bandes zu und von einem Walzgerüst des Steckelwalzwerks) vollständig verschließbar ist.In a winding furnace according to the preamble of claim 1 is therefore provided that the first furnace flap is rigid and rotatable about a first axis of rotation, and the rotatable roller together with its suspension forms a second furnace flap, which is rigid and movable about a second axis of rotation , And with the first and second oven door the oven opening (that for the transport of the tape to and from a rolling mill of the Steckel mill) is completely closed.

Die erste Ofenklappe gemäß der Erfindung ist nun - anders als bei der DE 10 2006 037 962 A1 - nicht mehr mehrteilig ausgeführt und wird nur über eine Drehachse bewegt. Die zweite Ofenklappe dient neben dem Verschließen der Ofenöffnung auch als Aufhängung für die Rolle, sodass sich insgesamt der mechanische Aufwand gegenüber der DE 10 2006 037 962 A1 verringert hat.The first oven door according to the invention is now - unlike the DE 10 2006 037 962 A1 - No longer executed in several parts and is only moved over a rotation axis. The second oven door serves in addition to closing the oven opening as a suspension for the role, so that the overall mechanical effort compared to the DE 10 2006 037 962 A1 has decreased.

Mit "starr" wird zum Ausdruck gebracht, dass die beiden erfindungsgemäßen Ofenklappen keine gegeneinander verschwenkbaren Bauteile aufweist, wie dies etwa für die Ofenklappe gemäß der DE 10 2006 037 962 A1 der Fall ist.By "rigid" is expressed that the two furnace flaps invention has no mutually pivotable components, such as the furnace door according to the DE 10 2006 037 962 A1 the case is.

Mit "vollständig verschließbar" ist gemeint, dass keine weiteren Bauelemente, wie Klappen, benötigt werden, um die Ofenöffnung, durch welche das Band geführt wird, zu verschließen. Es bedeutet nicht, dass die beiden erfindungsgemäßen Ofenklappen etwa ein gasdichtes Verschließen bewirken.By "fully closable" is meant that no other components, such as flaps, are needed to close the oven opening through which the belt is passed. It does not mean the two Furnace flaps invention cause about a gas-tight closure.

Bei einer bevorzugten Ausführungsform ist die der ersten Ofenklappe zugeordnete erste Drehachse im Bereich unterhalb der Ofentrommel angeordnet und die der zweiten Ofenklappe zugeordnete zweite Drehachse oberhalb der Drehachse der Ofentrommel. Das bedeutet, dass das freie Ende der ersten Ofenklappe zum Verschließen um die am anderen Ende der Ofenklappe befindliche Drehachse nach oben gedreht wird. Das freie Ende der zweiten Ofenklappe wird um die am anderen Ende der Ofenklappe befindliche zweite Drehachse gedreht, wobei sich das freie Ende im Betriebszustand unterhalb der zweiten Drehachse befindet. Diese Ausführungsform betrifft die gängige Ausführung von Wickelöfen, wo die Ofenöffnung einen Öffnungswinkel in der Größenordnung von 30° aufweist und in etwa in der Mitte des unteren Quadranten liegt, der dem Reversierwalzgerüst zugewandt ist. Die Quadranten beziehen sich auf den kreisrunden Querschnitt der Ofentrommel.In a preferred embodiment, the first axis of rotation associated with the first furnace flap is arranged in the region below the furnace drum and the second furnace flap associated second axis of rotation above the axis of rotation of the furnace drum. This means that the free end of the first oven door is turned up to close around the axis of rotation located at the other end of the oven door. The free end of the second oven door is rotated about the second axis of rotation located at the other end of the oven door, with the free end in the operating state below the second axis of rotation. This embodiment relates to the common design of winding ovens, where the oven opening has an opening angle of the order of 30 ° and is located approximately in the middle of the lower quadrant, which faces the reversing roll stand. The quadrants refer to the circular cross-section of the kiln drum.

Sieht man vor, dass die Drehachse der Rolle in jedem Betriebszustand unterhalb der Drehachse der Ofentrommel liegt, so ist damit sowohl eine gute Führung des Bandanfangs beim Einfädeln des Bandes in die Ofentrommel als auch beim Abwickeln des Bandes gewährleistet, liegt doch der Rollengang, auf dem das Band zu und von einem Walzgerüst geführt wird, in der Regel unterhalb des Gehäuses des Wickelofens, jedenfalls unterhalb der Ofentrommel.If one imagines that the axis of rotation of the roller in each operating state is below the axis of rotation of the furnace drum, so that both a good leadership of the beginning of the tape when threading the tape in the furnace drum and during unwinding of the tape is guaranteed, but is the roller conveyor on the the belt is guided to and from a rolling stand, usually below the housing of the winding furnace, at least below the furnace drum.

In einer sehr einfachen Ausführungsform kann die Aufhängung der Rolle plattenförmig sein. Die Aufhängung kann insbesondere als ebene Platte ausgeführt sein. Sie kann kreisbogenförmig um die an der Außenseite des Wickelofens angeordnete zweite Drehachse nach außen gebogen sein und das Gehäuse des Wickelofens kann eine entsprechende kreisbogenförmige Ausnehmung aufweisen, damit beim Drehen der Aufhängung bzw. der zweiten Ofenklappe kein Spalt zwischen der Aufhängung bzw. der zweiten Ofenklappe einerseits und dem Gehäuse des Wickelofens andererseits, das hier endet, entsteht und Wärme entweichen kann.In a very simple embodiment, the suspension of the roller may be plate-shaped. The suspension can be designed in particular as a flat plate. It can be bent in a circular arc around the arranged on the outside of the winding furnace second axis of rotation to the outside and the housing of the winding furnace can a corresponding Have circular arc-shaped recess so that when turning the suspension or the second furnace door no gap between the suspension and the second furnace door on the one hand and the housing of the winding furnace on the other hand, which ends here, arises and heat can escape.

Wenn vorgesehen ist, dass die Rolle am freien Ende der Aufhängung angeordnet ist, dann kann die Rolle zusätzlich als Führung des Bandes während des Auf- und Abwickelns verwendet werden. Sie bildet dann ein oberes Führungselement, während die erste Ofenklappe ein unteres Führungselement für das Band bildet.If it is provided that the roller is arranged at the free end of the suspension, then the roller can be used in addition as a guide of the belt during the winding and unwinding. It then forms an upper guide element, while the first furnace flap forms a lower guide element for the band.

Von Vorteil ist auch, wenn die Aufhängung der Rolle annähernd tangential zum äußeren Umfang der Rolle angeordnet ist, und zwar zwischen der Drehachse der Rolle und der Ofentrommel. Selbstverständlich muss dabei gewährleistet sein, dass die Rolle etwas über die Aufhängung nach innen Richtung Ofentrommel ragt, um das aufgewickelte Bandende festklemmen zu können.It is also advantageous if the suspension of the roller is arranged approximately tangentially to the outer circumference of the roller, between the axis of rotation of the roller and the oven drum. Of course, it must be ensured that the role something about the suspension protrudes in the direction of the furnace drum in order to clamp the wound tape end can.

Diese Art der Anordnung der Rolle an ihrer Aufhängung bedingt, dass ein Umfangsbereich der Rolle im geschlossenen Zustand des Wickelofens einen Teil der Außenseite des Wickelofens bildet, also dort nicht von dessen Gehäuse, von der ersten Ofenklappe oder von ihrer Aufhängung umgeben ist.This type of arrangement of the roller on its suspension requires that a peripheral portion of the roller forms a part of the outside of the winding furnace in the closed state of the winding furnace, so there is not surrounded by the housing, the first furnace door or its suspension.

Wenn die Rolle am freien Ende der Aufhängung angeordnet ist, dann kann die erste Ofenklappe im geschlossenen Zustand des Wickelofens an der Rolle anliegen. Dies hat etwa den Vorteil, dass die zweite Ofenklappe zum Schließen der Ofenöffnung nicht so weit Richtung Ofentrommel angehoben werden muss.If the roller is arranged at the free end of the suspension, then the first furnace flap can rest against the roller in the closed state of the winding furnace. This has the advantage, for example, that the second kiln flap does not have to be lifted so far in the direction of the kiln drum to close the kiln opening.

Bei dieser Ausführungsform ist zu beachten, dass es genau genommen zwei geschlossene Zustände gibt: Wurde ein Band aufgewickelt und das Bandende ganz in den Wickelofen eingezogen, dann muss die Rolle der zweiten Ofenklappe das Bandende gegen das aufgewickelte Band drücken, die Rolle wird daher näher an der Ofentrommel sein als wenn sich kein Band im Wickelofen befindet. In diesem Fall kann die Rolle weiter von der Ofentrommel entfernt sein, die erste Ofenklappe muss dann nicht so weit nach oben gedreht werden, um an der Rolle anzuliegen und die Ofenöffnung zu verschließen. Dieser zweite geschlossene Zustand unterscheidet sich also vom ersten, wo sich ein Band im Wickelofen befindet.In this embodiment, it should be noted that, strictly speaking, there are two closed states: one tape was wound up and the end of the tape was fully wound up retracted, then the role of the second kiln flap must press the ribbon end against the wound tape, the roll will therefore be closer to the kiln drum than if there is no ribbon in the winding kiln. In this case, the roll may be farther from the kiln drum, the first kiln flap then need not be turned up so as to rest against the roll and close the kiln opening. This second closed state thus differs from the first, where there is a band in the winding furnace.

In der Regel wird an der, der Ofentrommel zugewandten, Fläche der ersten Ofenklappe zumindest ein Leittisch zum Führen des Bandes vorgesehen sein.As a rule, at least one guide table for guiding the strip will be provided on the surface of the first furnace flap facing the furnace drum.

Eine weitere Ausführungsform sieht vor, dass unterhalb der Ofentrommel eine drehbare Leitklappe vorgesehen ist, deren freies Ende zum Einfädeln des Bandes in die Ofentrommel zu dieser gedreht werden kann.A further embodiment provides that below the furnace drum, a rotatable guide flap is provided, the free end can be rotated for threading the tape into the furnace drum to this.

Die Ofentrommel weist in der Regel ein Mittel, wie eine Einbuchtung, auf, in welcher der Bandanfang festgehalten werden kann. Die bevorzugte Art des Aufwickelns bei der gegenständlichen Erfindung ist der sogenannte Overwind-Modus, bei welchem der Bandanfang zuerst über die Ofentrommel geführt wird (und nicht unter der Ofentrommel durch und dann erst über die Ofentrommel). Entsprechend müssen in diesem Fall dann Mittel zum Festhalten des Bandanfangs vorgesehen werden, die den Bandanfang festhalten können, wenn der Bandanfang über die Ofentrommel in den Wickelofen eingebracht wird.The kiln drum usually has a means, such as a recess, in which the beginning of the tape can be held. The preferred way of winding in the subject invention is the so-called overwind mode, in which the beginning of the tape is first passed over the kiln drum (and not under the kiln drum and then over the kiln drum). Accordingly, then in this case means for holding the beginning of the tape must be provided, which can hold the beginning of the tape when the beginning of the tape is introduced over the furnace drum in the winding furnace.

Unterhalb der Ofentrommel können bewegliche Arme zur Einstellung der Bewegungsrichtung des Bandes beim Abwickeln vorgesehen sein.Below the oven drum, movable arms may be provided for adjusting the direction of movement of the belt during unwinding.

Das Verfahren zum Aufwickeln eines Bandes in einem erfindungsgemäßen Wickelofen sieht vor, dass

  • die erste Ofenklappe zum Einführen des Bandes in den Wickelofen geöffnet und dabei abgesenkt wird,
  • die zweite Ofenklappe in eine Aufwickelposition gebracht wird, in welcher die Rolle einen Abstand zur Ofentrommel aufweist und mit dem Band zu dessen Führung in Eingriff ist und
  • der Bandanfang über die Ofentrommel geführt, an der Ofentrommel befestigt und durch Drehen der Ofentrommel aufgewickelt wird.
The method for winding a tape in a winding furnace according to the invention provides that
  • the first oven door is opened for insertion of the tape in the winding furnace and thereby lowered,
  • the second oven door is brought into a winding position, in which the roller is spaced from the oven drum and is engaged with the tape for guiding it, and
  • the beginning of the tape is passed over the kiln drum, attached to the kiln drum and wound up by rotating the kiln drum.

Das Befestigen des Bandanfangs in der Ofentrommel kann durch die Leitklappe erfolgen, die nach oben zur Ofentrommel geklappt wird und den Bandanfang dem Mittel zum Festhalten des Bandanfangs, etwa einer Einbuchtung in der Ofentrommel, zuführt.The attachment of the beginning of the tape in the furnace drum can be done by the guide flap, which is folded up to the furnace drum and the beginning of the tape means for holding the beginning of the tape, such as a recess in the furnace drum, feeds.

In einer weiteren Ausgestaltung des Verfahrens ist vorgesehen, dass

  • die zweite Ofenklappe in Richtung Ofentrommel bewegt wird, sobald das Bandende zwischen Rolle und Ofentrommel angelangt ist, bis die Rolle das Bandende am aufgerollten Band fixiert hat, und
  • die erste Ofenklappe so lange nach oben gedreht wird, bis sie mit der Rolle in Eingriff ist. Dadurch wird die Ofenöffnung geschlossen und das Band kühlt nicht so stark ab als wenn der Wickelofen geöffnet wäre.
In a further embodiment of the method, it is provided that
  • the second oven door is moved in the direction of the oven drum, as soon as the end of the tape has arrived between the roller and the oven drum until the roller has fixed the end of the tape to the rolled up tape, and
  • the first oven door is turned up until it engages the roller. As a result, the furnace opening is closed and the belt does not cool as much as if the winding furnace were open.

WEGE ZUR AUSFÜHRUNG DER ERFINDUNGWAYS FOR CARRYING OUT THE INVENTION

Fig. 1 zeigt einen Längsschnitt durch einen schematisch dargestellten erfindungsgemäßen Wickelofens, in dem sich kein Band befindet. Der Wickelofen weist ein Gehäuse 1 auf, das nach außen hin isoliert ist. Im Inneren des Gehäuses 1 ist die Ofentrommel 3 erkennbar, die über ihre gesamte Länge eine Einbuchtung bzw. einen Spalt 4 aufweist, in den der Bandanfang 15 eingeführt und dort beim Aufwickeln festgeklemmt wird. Fig. 1 shows a longitudinal section through a schematically illustrated inventive winding furnace, in which there is no band. The winding furnace has a housing 1, which is insulated to the outside. Inside the housing 1, the furnace drum 3 can be seen, which has over its entire length a recess or a gap 4, in which the beginning of the tape 15 is inserted and clamped there during winding.

Das Gehäuse 1 wird, siehe hierzu auch Fig. 2, durch eine erste Ofenklappe 5, die um eine erste Drehachse 6 drehbar ist, und eine zweite Ofenklappe 7, die um eine zweite Drehachse 8 drehbar ist, verschlossen. Die zweite Ofenklappe besteht aus einer plattenförmigen Aufhängung 9, an deren freien Ende die Rolle 10 drehbar gelagert ist. Die Rolle 10 kann generell auch mit einem nicht dargestellten Antrieb angetrieben werden, um das Abwickeln des Bandes zu unterstützen. Auch die Aufhängung 9 weist einen Antrieb auf, um ihre Position relativ zur Ofentrommel 3 einstellen zu können.The housing 1 is, see also Fig. 2 , by a first oven door 5, which is rotatable about a first axis of rotation 6, and a second oven door 7, which is rotatable about a second axis of rotation 8, closed. The second oven door consists of a plate-shaped suspension 9, at the free end of the roller 10 is rotatably mounted. The roller 10 can generally also be driven by a drive, not shown, to assist in unwinding the belt. The suspension 9 has a drive in order to adjust their position relative to the furnace drum 3 can.

In Fig. 1 befindet sich der Wickelofen im oben beschriebenen zweiten geschlossenen Zustand, wo die Rolle 10 von der Ofentrommel entfernt ist die erste Ofenklappe 5 nicht so weit nach oben gedreht werden muss, um an der Rolle 10 anzuliegen und die Ofenöffnung zu verschließen. Das freie Ende der ersten Ofenklappe 5 liegt hier an der Unterseite der Rolle 10 an, erste 5 und zweite Ofenklappe 7 schließen einen stumpfen Winkel ein. Die Leitklappe 11, die dem Einfädeln des Bandanfangs 15 in den Spalt 4 der Ofentrommel 3 dient, ist hier genau unterhalb der Ofentrommel 3 im Gehäuse 1 des Wickelofens versenkt angeordnet.In Fig. 1 is the winding furnace in the second closed state described above, where the roller 10 is removed from the oven drum, the first oven door 5 does not have to be turned up so far to rest on the roller 10 and to close the oven opening. The free end of the first oven door 5 is here at the bottom of the roller 10, first 5 and second oven door 7 include an obtuse angle. The guide flap 11, which serves to thread the strip beginning 15 in the gap 4 of the furnace drum 3, is here sunk just below the furnace drum 3 in the housing 1 of the winding furnace.

Die erste Ofenklappe 5 ist am Gehäuse 1 des Wickelofens angelenkt oder auf einem unterhalb des Wickelofens befindlichen Teil eines Rollgangrahmens, ebenso ist die zweite Ofenklappe 7 im oberen Endbereich des Gehäuses angelenkt. Die Rolle 10 ist am freien Ende der Aufhängung 9 angeordnet ist, uns zwar annähernd tangential zum äußeren Umfang der Rolle 10 zwischen der Drehachse der Rolle 10 und der Ofentrommel 3. Selbstverständlich ragt die Rolle 10 etwas über die Aufhängung 9 nach innen Richtung Ofentrommel 3, um das aufgewickelte Bandende 14 festklemmen zu können. Der Durchmesser der Rolle 10 beträgt etwa die Hälfte bis ein Drittel des Durchmessers der Ofentrommel 3.The first oven door 5 is hinged to the housing 1 of the winding furnace or located on a below the winding furnace part of a roller table frame, as well as the second oven door 7 is articulated in the upper end of the housing. The roller 10 is arranged at the free end of the suspension 9, although approximately tangential to the outer circumference of the roller 10 between the axis of rotation of the roller 10 and the furnace drum 3. Of course, the roller 10 projects slightly beyond the suspension 9 in the direction of the furnace drum 3, to be able to clamp the wound tape end 14. The diameter of the roller 10 is about half to one third of the diameter of the furnace drum. 3

Unterhalb des Wickelofens ist ein Rollengang mit vielen Transportrollen 12 vorgesehen, mit welchen das Band 13 zum und vom Wickelofen oder, wenn es fertig gewalzt ist, unter dem Wickelofen hindurch geführt werden kann. Rechts vom Wickelofen führt der Rollengang zu zumindest einem hier dargestellten Walzgerüst. Zwischen dem Wickelofen und dem Walzgerüst können weitere Einrichtungen angeordnet sein, die das Ein- und Ausfädeln des Bandes 13 in bzw. aus dem Wickelofen und in bzw. aus dem Walzgerüst unterstützen, und die dem Fachmann hinreichend bekannt sind.Below the winding furnace, a roller conveyor with many transport rollers 12 is provided, with which the belt 13 to and from the winding furnace or, when it is finished rolled, can be performed under the winding furnace. To the right of the winding furnace, the roller conveyor leads to at least one rolling stand shown here. Further means may be arranged between the winding furnace and the roll stand, which support the threading and unthreading of the strip 13 into and out of the winding furnace and into and out of the roll stand, and which are well known to the person skilled in the art.

In Fig. 2 ist der Wickelofen aus Fig. 1 beim Einfädeln des Bandes dargestellt. Die Stellung der zweiten Ofenklappe 7 hat sich im Vergleich zu Fig. 1 nicht geändert, die zweite Ofenklappe 7 ist etwas nach innen zur Ofentrommel 3 geneigt.In Fig. 2 is the winding oven off Fig. 1 when threading the tape shown. The position of the second oven door 7 has compared to Fig. 1 not changed, the second oven door 7 is inclined slightly inwards to the oven drum 3.

Die erste Ofenklappe 5 ist geöffnet, ihr freies Ende bzw. der auf ihr angeordnete Leittisch wird bis auf die Ebene des Rollengangs abgesenkt, um das von rechts einlaufende Band 13 nach oben in den Wickelofen zu leiten. Die Leitklappe 11, deren Drehachse benachbart zur oder gleich der ersten Drehachse 6 der ersten Ofenklappe 5 ist, ist ebenfalls nach oben geklappt, sodass ihr freies Ende in den Spalt 4 der Ofentrommel übergeht. Die Ofentrommel 3 bleibt so lange in dieser Position stehen, bis der Bandanfang 15 durch den Spalt 4 genügend weit in das Innere der Ofentrommel 3 eingeführt ist. Dann erst beginnt sich die Ofentrommel 13 gegen den Uhrzeigersinn zu drehen, das Band 13 wird aufgewickelt.The first oven door 5 is opened, its free end or arranged on her control table is lowered to the level of the roller conveyor to guide the incoming from the right belt 13 upwards in the winding furnace. The guide flap 11, whose axis of rotation is adjacent to or equal to the first axis of rotation 6 of the first oven door 5, is also folded upwards, so that their free end merges into the gap 4 of the oven drum. The kiln drum 3 remains in this position until the beginning of the strip 15 is inserted sufficiently far into the interior of the kiln drum 3 through the gap 4. Then only the kiln drum 13 begins to rotate counterclockwise, the tape 13 is wound up.

In Fig. 3, wo der Wickelofen beim Aufwickeln des Bandes 13 dargestellt ist, ist die Leitklappe 11 bereits wieder eingefahren, die Position von erster 5 und zweiter Ofenklappe 7 hat sich im Vergleich zu Fig. 2 nicht verändert. Das Band 13 läuft über die Rolle 10 zur Ofentrommel 3 und wird gespannt, damit das Band 13 straff aufgewickelt werden kann. Hier sind auch in einer waagrechten Ebene unterhalb der Ofentrommel 3, zwischen dieser und dem Gehäuse 1 bzw. der Leitklappe 11, angeordnete bewegliche Arme 2 eingezeichnet, welche das Bandende 14 (den Bandkopf) beim Abwickeln in die richtige Richtung stoßen.In Fig. 3 , where the winding furnace is shown during winding of the belt 13, the guide flap 11 is already retracted again, the position of the first 5 and second kiln flap 7 has compared to Fig. 2 not changed. The belt 13 passes over the roller 10 to the kiln drum 3 and is tensioned so that the belt 13 can be wound tightly. Here are also in a horizontal plane below the furnace drum 3, between this and the housing 1 and the guide flap 11, arranged movable arms 2 located, which push the tape end 14 (the tape head) during unwinding in the right direction.

Sobald das Bandende 14 des Bandes 13 zwischen Rolle 10 und Ofentrommel 3 angelangt ist, siehe Fig. 4, wird die Aufhängung 9 nach innen gefahren, bis die Rolle 10 das Bandende 14 am aufgerollten Band fixiert hat. Die erste Ofenklappe 5 wird so lange nach oben gedreht, bis sie mit der Rolle 10 in Eingriff ist. Sie liegt an der Außenseite der Rolle 10 an, die Ofenöffnung ist damit verschlossen. Dies entspricht dem weiter oben beschriebenen ersten geschlossenen Zustand. Aufhängung 9 und erste Ofenklappe 5 sind annähernd parallel ausgerichtet.Once the tape end 14 of the belt 13 between the roller 10 and the furnace drum 3 has arrived, see Fig. 4 , the suspension 9 is moved inwards until the roller 10 has fixed the strap end 14 on the rolled-up band. The first oven door 5 is turned up until it engages with the roller 10. It lies against the outside of the roller 10, the oven opening is closed. This corresponds to the first closed one described above Status. Suspension 9 and first oven door 5 are aligned approximately parallel.

Beim Abwickeln des Bandes, siehe Fig. 5, behalten die zweite Ofenklappe 7 und die Rolle 10 vorerst ihre Position relativ zur Ofentrommel 3. Die erste Ofenklappe 5 wird bis zum Rollengang geöffnet, erst dann beginnt sich die Rolle 10 aufgrund ihres Antriebs gegen den Uhrzeigersinn zu drehen, die Ofentrommel im Uhrzeigersinn. Das Bandende 14 gelangt nach unten und gleitet entlang der unteren Ofenklappe 5 zum Rollengang, wo es mit weiteren Einrichtungen wieder in das Walzgerüst eingefädelt wird. Die Rolle 10 bleibt solange gegen die Ofentrommel 3 bzw. das darauf aufgewickelte Band 13 gedrückt, bis der Bandanfang 15 den Wickelofen verlassen hat. Dann werden die Ofenklappen 5, 7 bis zum nächsten Aufwickeln eines Bandes wieder in die Positionen gemäß Fig. 1 gebracht.When unwinding the tape, see Fig. 5 , keep the second oven door 7 and the roller 10 for the time being their position relative to the oven drum 3. The first oven door 5 is opened to the roller conveyor, only then begins to rotate the roller 10 due to its drive counterclockwise, the oven drum in a clockwise direction. The tape end 14 comes down and slides along the lower oven door 5 to the roller conveyor, where it is threaded with other facilities back into the rolling stand. The roller 10 remains pressed against the kiln drum 3 and the wound thereon tape 13 until the beginning of the tape 15 has left the winding oven. Then, the oven flaps 5, 7 until the next winding of a tape back to the positions according to Fig. 1 brought.
