Description

Die Erfindung betrifft einen Haspelofen mit einer Bandhaspeleinrichtung. Die Bandhaspeleinrichtung umfasst eine Haspelwelle, eine auf der Haspelwelle abgestützte Haspeltrommel und mindestens eine Bügelklemme. Die Haspelwelle durchsetzt eine den Innenraum des Haspelofens abgrenzende Ofenwand und ist außerhalb des Haspelofens in Stützlagern drehbar abgestützt. Die Haspeltrommel und die mindestens eine Bügelklemme sind durch ein Verbindungselement zueinander positioniert und zwischen der Haspeltrommel und der mindestens einen Bügelklemme ist ein Spalt zur Aufnahme eines Bandkopfes eingestellt.The invention relates to a coiler oven with a band reeling device. The band reeling device comprises a reel shaft, a reel drum supported on the reel shaft and at least one hoop clamp. The reel shaft passes through an oven wall delimiting the interior of the reel furnace and is rotatably supported outside the reel furnace in support bearings. The reel drum and the at least one U-clamp are positioned by a connecting element to each other and between the reel drum and the at least one U-clamp is set a gap for receiving a tape head.

Bandhaspeleinrichtungen dieser Art werden vorzugsweise in Verbindung mit Steckelwalzwerken zum Aufwickeln, Zwischenspeichern und Abwickeln von warmgewalztem bandförmigem Gut zwischen aufeinander folgenden Walzstichen verwendet.Bandhaspeleinrichtungen of this type are preferably used in conjunction with Steckel rolling mills for winding, caching and unwinding of hot rolled strip-shaped material between successive rolling passes.

Steckeltrommeln weisen üblicherweise einen hohlzylindrischen Trommelkörper mit einem Längsschlitz auf, der auf die maximale Walzbandbreite abgestimmt ist. Der zylindrische Trommelkörper bildet mit seiner Mantelfläche die Wickelfläche für die erste Bandwindung und der Längsschlitz eine Eintrittsöffnung für den Bandkopf des Warmbandes. Durch den Schlitz liegt ein offener Querschnitt des Trommelkörpers vor, welcher ein im Vergleich mit einem geschlossenen Querschnitt stark vermindertes Torsionswiderstandsmoment aufweist. Diese Schwächung des Trommelkörpers führt im Laufe der Einsatzdauer der Trommel zu einer Abflachung ihrer Kreisgeometrie, verändert die Schlitzgeometrie und verursacht beim Wickeln zusätzlich Bandzugschwankungen, welche sich negativ auf die Stabilität des Wickelvorgang auswirken. An den beiden Schlitzenden treten weiters hohe lokale Kerbspannungen im Trommelmantel auf. Diese Spannungsbilder, die Verformungsneigung und der Einfluss der hohen Betriebstemperatur setzen die Lebensdauer der Steckeltrommel stark herab, sodass bereits nach einer Produktionsmenge von etwa 500.000 to Warmband ein Trommelwechsel notwendig wird.Steckel drums usually have a hollow cylindrical drum body with a longitudinal slot, which is tuned to the maximum rolling bandwidth. The cylindrical drum body forms with its lateral surface the winding surface for the first band winding and the longitudinal slot an inlet opening for the tape head of the hot strip. Through the slot there is an open cross section of the drum body, which has a greatly reduced Torsionswiderstandsmoment compared with a closed cross-section. This weakening of the drum body leads in the course of the period of use of the drum to a flattening of its circular geometry, changes the slot geometry and caused during winding additionally Bandzugschwankungen, which have a negative effect on the stability of the winding process. At the two slot ends further high local notch stresses occur in the drum shell. These tension patterns, the tendency to deformation and the influence of the high operating temperature significantly reduce the life of the Steckel drum, so that a drum change is necessary after a production volume of about 500,000 tons of hot strip.

Aus der DE-A 909 577 , der DE 21 10 317 A1 und der GB-A 693 397 sind bereits Haspelöfen mit einer Bandhaspeleinrichtung der eingangs beschriebenen Art bekannt. Die Haspeltrommel umfasst jeweils einen Mittelteil, der auf einer Haspelwelle aufgeschoben ist, und zwei in seitlichen Schilden kippbar gelagerte Trommelsegmente. Vom Mittelteil und jedem der Trommelsegmente wird eine keilförmige Aufnahmeöffnung für den eintretenden Bandkopf eines Warmbandes gebildet. Unmittelbar nach dem Eintritt des Warmbandes beginnt sich die Haspeltrommel zu drehen und wickelt das Warmband auf. Keine dieser bekannten Ausführungsformen bietet die Möglichkeit einer individuellen Einstellung der Spaltweite in Abhängigkeit von der Banddicke des eintretenden Warmbandes, sowie einer definierten Klemmung des Warmbandes.From the DE-A 909 577 , of the DE 21 10 317 A1 and the GB-A 693 397 Coiler ovens are already known with a band reeling device of the type described above. The reel drum each comprises a central part, which is pushed onto a reel shaft, and two drum segments tiltably mounted in side shields. From the central part and each of the drum segments, a wedge-shaped receiving opening for the incoming tape head of a hot strip is formed. Immediately after the entry of the hot strip, the reel drum begins to rotate and winds up the hot strip. None of these known embodiments offers the possibility of an individual adjustment of the gap width as a function of the strip thickness of the incoming hot strip, as well as a defined clamping of the hot strip.

Der vielteilige Aufbau einer Haspeltrommel unter axialer Federspannung, wie er bei einer Bandhaspeleinrichtung gemäß der DE 21 10 317 A1 bekannt ist, erfordert ein aufwändiges System von Nocken, die von festgelegten Bügelelementen ausgehend in Ausnehmungen der einzelnen Haspeltrommelelemente ragen und als Mitnehmer wirken, gleichzeitig aber auch zumindest teilweise als Anschläge für das eintretende Warmband. Bereits in der DE 21 10 317 A1 wird auf die hohe Verschleißanfälligkeit dieser Nocken und der Haspelwellenelemente hingewiesen, die mit besonders harten und verschleißfesten Überzügen ausgestattet werden müssen. Derartige Konstruktionen können bei Temperaturbelastungen von 800° C bis 1000° C nicht wirtschaftlich eingesetzt werden.The multi-part construction of a reel drum under axial spring tension, as in a band reeling device according to the DE 21 10 317 A1 is known requires a complex system of cams, which protrude from fixed bracket elements, starting in recesses of the individual reel drum elements and act as a driver, but at the same time also at least partially as stops for the incoming hot strip. Already in the DE 21 10 317 A1 Attention is drawn to the high susceptibility to wear of these cams and the reel shaft elements, which must be equipped with particularly hard and wear-resistant coatings. Such constructions can not be used economically at temperatures of 800 ° C to 1000 ° C.

Aufgabe der vorliegenden Erfindung ist es daher, die Nachteile des bekannten Standes der Technik zu vermeiden und einen Haspelofen mit einer Bandhaspeleinrichtung vorzuschlagen, bei der die Lebensdauer der Haspeltrommel durch konstruktive Maßnahmen wesentlich erhöht wird. Weiters soll eine banddickenabhängige Einstellung des Einlaufspaltes für das Warmband sichergestellt werden und Bandzugschwankungen weitgehend minimiert werden.The object of the present invention is therefore to avoid the disadvantages of the known prior art and to propose a reel furnace with a band reeling device, in which the life of the reel drum is substantially increased by design measures. Furthermore, a band thickness-dependent adjustment of the inlet gap for the hot strip is to be ensured and Bandzugschwankungen be largely minimized.

Diese Aufgabe wird ausgehend von einer Einrichtung der eingangs beschriebenen Art dadurch gelöst, dass die Haspeltrommel als geschlossener Körper und das die Bügelklemme in ihrer Radialposition zur Haspeltrommel bestimmende Verbindungselement als Stelleinrichtung zur Festlegung einer bestimmten Spaltweite zwischen Haspeltrommel und Bügelklemme und zur Klemmung eines in den Spalt eingetretenen Bandkopfes ausgebildet ist. Die Ausgestaltung der Haspeltrommel als geschlossener, auf der Haspelwelle befestigter Hohlkörper, insbesondere ohne einen Längsschlitz im Trommelmantel und ohne andersartige Teilung und Segmentierung des Trommelmantels, erhöht die Lebensdauer der Haspeltrommel ganz wesentlich.This object is achieved on the basis of a device of the type described above, characterized in that the reel drum as a closed body and the U-clamp in its radial position to the reel drum determining connecting element as a setting device for establishing a certain gap width between reel drum and U-clamp and for clamping a occurred in the gap Band head is formed. The design of the reel drum as a closed, mounted on the reel shaft hollow body, in particular without a Longitudinal slot in the drum shell and without other division and segmentation of the drum shell, increases the life of the reel drum quite significantly.

Um insbesondere bewegliche Teile der Stelleinrichtung von hohen thermischen Einwirkungen fern zu halten, wird nach einer vorteilhaften Ausführungsform vorgeschlagen, dass die Haspelwelle und die Bügelklemme eine den Innenraum des Haspelofens abgrenzenden Ofenwand durchsetzen und die Stelleinrichtung außerhalb des Innenraums des Haspelofens angeordnet ist. Vorzugsweise ist die Stelleinrichtung drehfest auf der Haspelwelle angeordnet und die Bügelklemme an der Stelleinrichtung relativbeweglich zur Haspelwelle festgelegt.In particular, to keep moving parts of the adjusting device away from high thermal effects, it is proposed according to an advantageous embodiment that the reel shaft and the U-clamp penetrate the furnace wall delimiting the interior of the reel furnace and the positioning device is arranged outside the interior of the reel furnace. Preferably, the adjusting device is rotatably mounted on the reel shaft and fixed the U-clamp on the adjusting device relative to the reel shaft.

Zur Minimierung von Wärmeverlusten im Durchtrittsbereich der Haspelwelle und der zur Drehachse der Haspelwelle exzentrisch mitrotierende Bügelklemme durch die Ofenwand ist es zweckmäßig, wenn die Ofenwand im Durchtrittsbereich der Haspelwelle und der Bügelklemme als eine mit der Haspelwelle mitrotierenden Scheibe ausgebildet ist. Der weitgehend dichte Übergang von der rotierenden Scheibe zur stationären Ofenwand erfolgt durch eine Dichtung aus einem hitzebeständigen Dichtmaterial, vorzugsweise einer Dichtung ähnlich einem hitzebeständigen Faltenbalg.To minimize heat losses in the passage region of the reel shaft and the rotation axis of the reel shaft eccentrically mitrotierende U-clamp through the furnace wall, it is advantageous if the furnace wall is formed in the passage region of the reel shaft and the U-clamp as a co-rotating with the reel shaft pulley. The largely dense transition from the rotating disk to the stationary furnace wall is made by a seal made of a heat-resistant sealing material, preferably a seal similar to a heat-resistant bellows.

Zweckmäßig umfasst die Stelleinrichtung nach einer ersten möglichen Ausführungsform einen Tragrahmen, der an der Trommelwelle drehfest befestigt ist und dem Führungen zugeordnet sind, an denen eine die Bügelklemme tragende Kulisse mit Gegenführungen geführt ist. Die Führungen und Gegenführungen sind so ausgebildet, dass sie eine die Spaltweite des Spaltes zwischen der Bügelklemme und der Haspeltrommel verändernde Relativbewegung zulassend ausgebildet sind. Die Führungen am Tragrahmen und die Gegenführungen an der Kulisse sind hierbei radial zur Drehachse der Haspelwelle ausgerichtet.Appropriately, the adjusting device according to a first possible embodiment comprises a support frame which is rotatably attached to the drum shaft and associated with the guides on which a bracket carrying the backdrop is guided with counter guides. The guides and counter-guides are designed so that they are permitting a relative to the gap width of the gap between the U-clamp and the reel drum relative change. The guides on the support frame and the counter guides on the slide are in this case aligned radially to the axis of rotation of the reel shaft.

Auch eine indirekte Befestigung des Tragrahmens auf der Haspelwelle ist möglich, indem der Tragrahmen an der mit der Haspelwelle mitrotierenden Scheibe der Ofenwand befestigt oder unmittelbar in die mitrotierende Scheibe der Ofenwand integriert ist.An indirect attachment of the support frame on the reel shaft is possible by the support frame attached to the co-rotating with the reel shaft disc of the furnace wall or is integrated directly into the co-rotating disk of the furnace wall.

Figur 1 zeigt in einer schematischen Darstellung einen Vertikalschnitt durch einen Haspelofen mit einer Bandhaspeleinrichtung entlang der Drehachse einer Haspelwelle. Ein derartiger Haspelofen mit einer Bandhaspeleinrichtung wird zum Aufwickeln, Speichern und Abwickeln von warmgewalztem Stahlband in einer Reversier- Walzanlage verwendet. FIG. 1 shows a schematic representation of a vertical section through a coiler furnace with a belt reel along the axis of rotation of a reel shaft. Such a coiler oven with a belt coiler is used for winding, storing and unwinding hot rolled steel strip in a reversing mill.

Der Haspelofen 1 besteht aus einem weitgehend geschossenen Ofengehäuse 2, das von mehreren mit einer wärmedämmenden Auskleidung versehenen Ofenwänden 2a, 2b, 2c gebildet ist. Im Innenraum 3 des Haspelofens, dessen Raumtemperatur regelbar einstellbar ist, befinden sich wesentliche Bauteile der Bandhaspeleinrichtung 4.The coiler 1 consists of a largely geschossen oven housing 2, which is formed by a plurality of provided with a heat-insulating lining furnace walls 2a, 2b, 2c. In the interior 3 of the coiler furnace, the room temperature is adjustable adjustable, there are essential components of the tape reeling device. 4

Eine Haspelwelle 6 ist um eine Drehachse 7 drehbar angeordnet ist. Die Haspelwelle 6 durchsetzt die seitlichen Ofenwände 2a, 2b und ist in Stützlagern 8, 9 in einem thermisch nicht belasteten Bereich außerhalb des Ofengehäuses 2 gelagert. Die Haspelwelle 6 ist mit einem regelbaren Drehantrieb 10 gekoppelt.A reel shaft 6 is arranged rotatably about a rotation axis 7. The reel shaft 6 passes through the lateral furnace walls 2a, 2b and is mounted in support bearings 8, 9 in a non-thermally stressed area outside the furnace housing 2. The reel shaft 6 is coupled to a controllable rotary drive 10.

Die Haspeltrommel 11 ist als Hohlkörper mit einer durchgehend geschlossenen, zylindrischen Mantelfläche 12 ausgeformt und auf der Haspelwelle 6 drehfest positioniert. Eine Bügelklemme 14, die im radialen Abstand zur Mantelfläche 12 der Haspeltrommel 11 angeordnet ist und sich längs dieser erstreckt, bildet einen Spalt 15 zur Mantelfläche der Haspeltrommel. In einem Querschnitt normal zur Drehachse 7 der Haspelwelle bilden die Haspeltrommel 11 und die Bügelklemme 14 eine gemeinsame Außenkontur, die annähernd einer Kreisform entspricht, wodurch ein ausreichender Rundlauf der Bandhaspeleinrichtung gewährleistet ist.The reel drum 11 is formed as a hollow body with a continuous closed cylindrical surface 12 and positioned rotatably on the reel shaft 6. A U-clamp 14, which is arranged at a radial distance to the lateral surface 12 of the reel drum 11 and extends along this, forms a gap 15 to the lateral surface of the reel drum. In a cross section normal to the axis of rotation 7 of the reel shaft, the reel drum 11 and the bracket clamp 14 form a common outer contour, which corresponds approximately to a circular shape, whereby a sufficient concentricity of the tape reeling device is ensured.

Der von der Haspeltrommel 11 und der Bügelklemme 14 gebildete Spalt 15 nimmt den Bandkopf eines in den Haspelofen eintretenden Warmbandes auf, startet unmittelbar mit der Drehbewegung der Bandhaspeleinrichtung, klemmt das Warmband zwischen der Haspeltrommel und der Bügelklemme und wickelt das Warmband zu dem mit strichpunktierten Linien angedeuteten Bund B auf.The gap 15 formed by the reel drum 11 and the U-clamp 14 accommodates the tape head of a hot strip entering the reel furnace, starts immediately with the rotary motion of the tape reel, clamps the hot strip between the reel drum and the U-clamp and winds the hot strip to the indicated by dotted lines Bund B on.

Die Bügelklemme 14 erstreckt sich in Richtung der Drehachse 7 ebenfalls durch die Ofenwände 2a, 2b und ist außerhalb des Ofengehäuses 2 durch ein Verbindungselement 16, welches die Funktionen der Stelleinrichtung 17 erfüllt, in seiner Relativposition zur Haspeltrommel 11 festgelegt. Im Durchtrittsbereich der Haspelwelle 6 und der Bügelklemme 14 durch die Ofenwände 2a, 2b sind diese Ofenwände von mit der Haspelwelle und der Bügelklemme mitrotierenden Scheiben 23, 24 gebildet. Diese Scheiben sind mit der Haspelwelle 6 drehfest verbunden und zu den anschließenden feststehenden Ofenwänden 2a, 2b durch Dichtelemente 25, 26, beispielsweise Dichtungen nach Art eines hitzebeständigen Faltenbalgs, abgedichtet, damit der Eintritt von Umgebungsluft in den heißen Innenraum des Haspelofens und damit eine örtliche Abkühlung des Warmbandes sicher vermieden wird.The U-clamp 14 also extends through the furnace walls 2a, 2b in the direction of the axis of rotation 7 and is fixed in its relative position to the capstan drum 11 outside the oven housing 2 by a connecting element 16 which fulfills the functions of the adjusting device 17. In the passage area of the reel shaft 6 and the U-clamp 14 through the furnace walls 2 a, 2 b, these furnace walls are formed by disks 23, 24 co-rotating with the reel shaft and the U-clamp. These discs are rotatably connected to the reel shaft 6 and to the subsequent fixed furnace walls 2a, 2b sealed by sealing elements 25, 26, for example seals like a heat-resistant bellows, so that the entry of ambient air into the hot interior of the coiler furnace and thus a local cooling the hot strip is avoided safely.

Beiderseits des Ofengehäuses sind die Stützlager 8, 9 auf stationären Tragrahmen 20, 21 abgestützt.On both sides of the furnace housing, the support bearings 8, 9 supported on stationary support frame 20, 21.

Prinzipiell ist natürlich eine beidseitige symmetrische Abstützung der Haspelwelle und der Bügelklappe notwendig.In the Figures 2 and 3 For better clarity, the adjusting device 17 according to the invention between the reel shaft 6 and the U-clamp 14, the support bearing 8 for Drehabstützung the reel drum 6 and the furnace wall 2a with the disc 24 only in a half of the picture. In principle, a bilateral symmetrical support of the reel shaft and the shackle flap is of course necessary.

Die Bandhaspeleinrichtung 4 umfasst, wie aus der Fig. 2 entnehmbar, die Haspelwelle 6, auf der die Haspeltrommel 11 drehfest angeordnet ist. Diesen Bauteilen ist eine Innenkühlung mit Kühlmittelzuleitungen und Kühlmittelableitungen durch die zentrale Haspelwelle zugeordnet.The tape reeling device 4 comprises, as shown in Fig. 2 removed, the reel shaft 6, on which the reel drum 11 is arranged rotationally fixed. These components are assigned an internal cooling with coolant supply lines and coolant discharges through the central reel shaft.

Die Stelleinrichtung 17 wird von einem Anstellrahmen 32 und einer Kulisse 33 gebildet. Der Anstellrahmen 32 umfasst ein scheibenförmiges Basiselement 34, welches trichterwandförmige Führungen 35, 35a aufweist, die gemeinsam einen ringförmigen Aufnahmeraum für die Kulisse 33 bilden. Das scheibenförmige Basiselement 34 weist mittig angeordnet eine Durchtrittsöffnung für die Haspelwelle 6 auf. Eine Seite des Basiselementes 34 ist von einer Grundplatte 36 gebildet, an der mehrere Verschiebestempel 37 angeschweißt sind (Fig.4), um eine gleichmäßige Anstellung des Basiselementes zu erreichen. Diese sind in Führungsrahmen 38 eines stationären Tragrahmens 21 parallel zur Richtung der Drehachse 7 der Haspelwelle 6 verschiebbar gelagert. An jedem Verschiebestempel 37 ist ein Druckmittelzylinder 39 angelenkt, der am Führungsrahmen 38 des stationären Tragrahmens 21 abgestützt ist. Die Kulisse 33 weist Gegenführungen 40 auf, die von Rollen 41 gebildet werden, die je nach Belastungsrichtung A, B des Druckmittelzylinders 39 an einer der Führungen 35, 35a abrollen.The adjusting device 17 is formed by a Anstellrahmen 32 and a backdrop 33. The Anstellrahmen 32 includes a disc-shaped base member 34 which funnel wall-shaped guides 35, 35a, which together form an annular receiving space for the gate 33. The disc-shaped base member 34 has centrally disposed a passage opening for the capstan shaft 6. One side of the base element 34 is formed by a base plate 36 to which a plurality of displacement dies 37 are welded ( Figure 4 ) to achieve a uniform employment of the base element. These are slidably mounted in guide frame 38 of a stationary support frame 21 parallel to the direction of the axis of rotation 7 of the capstan shaft 6. At each displacement stamp 37, a pressure medium cylinder 39 is articulated, which is supported on the guide frame 38 of the stationary support frame 21. The link 33 has counter guides 40, which are formed by rollers 41, which roll depending on the loading direction A, B of the pressure medium cylinder 39 on one of the guides 35, 35a.

Um eine Öffnung des Spaltes 15 zur Aufnahme des Bandkopfes zu erreichen, wird der Druckmittelzylinder 39 so belastet, dass der Verschiebestempel 37 in Richtung des Pfeils B bewegt wird. Zwangsweise kommt es hierbei zu einer radialen Auswärtsbewegung der Kulisse 33, wodurch auch die Bügelklemme 14 nach auswärts im Sinne einer Spaltvergrößerung bewegt wird. Wenn ein Klemmen des Bandkopfes nach seinem Eintritt in den Spalt 15 erreicht werden soll, erfolgt eine Belastung des Druckmittelzylinders 39 so, dass der Verschiebestempel 37 in Richtung des Pfeils A bewegt wird. Zwangsweise kommt es dann zu einer radialen Einwärtsbewegüng der Kulisse 33, wodurch auch die Bügelklemme 14 einwärts bewegt wird.In order to achieve an opening of the gap 15 for receiving the tape head, the pressure medium cylinder 39 is loaded so that the displacement punch 37 is moved in the direction of arrow B. Forcibly, this results in a radial outward movement of the link 33, whereby the U-clamp 14 is moved to the outside in the sense of a gap enlargement. If a clamping of the tape head to be achieved after its entry into the gap 15, a load of the pressure medium cylinder 39 is carried out so that the displacement punch 37 is moved in the direction of arrow A. Forcibly, it then comes to a radial inward movement of the link 33, whereby the U-clamp 14 is moved inwards.
