Description

Die Erfindung betrifft eine Einrichtung zum wahlweisen Überleiten von biegsamen und relativ biegesteifen Profilquerschnitten verschiedener Querschnittsform bei kontinuierlichen Feinstahl- bzw. Mittelstahl-Walzstrassen, bei welchen in zwei zueinander etwa parallelen Walzlinien jeder Walzlinie ein Kühlbett zugeordnet ist. Jedem Kühlbett ist ein schwenkbeweglicher, als Auflaufrollgang ausgebildeter Weichenabschnitt vorgeordnet, der es ermöglicht, entweder aus beiden Walzlinien gleichzeitig je ein Kühlbett oder aus jeweils einer Waiziinie das eine oder das andere der anderen Walzlinie zugeordnete Kühlbett zu beschicken.The invention relates to a device for the optional transfer of flexible and relatively rigid profile cross sections of different cross-sectional shape in continuous fine steel or medium steel rolling mills, in which a cooling bed is assigned to each rolling line in two roughly parallel rolling lines. Each cooling bed is preceded by a pivotable switch section designed as an overrun roller table, which makes it possible to feed either one cooling bed from both rolling lines at the same time or one or the other cooling bed assigned to the other rolling line from each of the rolling lines.

Ausgehend von dem durch die DE-PS 1 249 801 bekannten Stand der Technik ist einer Walzstrasse für Fein- und Mittelstahl mit einem breiten Walzprogramm hinsichtlich Profilform und Profilquerschnittsabmessungen in der sogenannten Mehrlinienanordnung (DE-PS 1 057 049) zwischen den Walzstrassen in zwei etwa parallelen Walzlinien und den diesen jeweils zugeordneten Kühlbetten ein sehr langer, als Auslaufrollgang ausgebildeter Rollgangsabschnitt in beiden Walzlinien als Schwenkweiche vorgesehen. Die beiden Rollgangsabschnitte sind hinsichtlich der Schwenkbewegung gemeinsam oder unabhängig voneinander steuerbar.Starting from the prior art known from DE-PS 1 249 801, a rolling mill for fine and medium steel with a wide rolling program with regard to profile shape and profile cross-sectional dimensions in the so-called multi-line arrangement (DE-PS 1 057 049) between the rolling trains in two approximately parallel Rolling lines and the cooling beds assigned to each of them are provided with a very long roller table section designed as a run-out roller table in both rolling lines as a pivoting switch. The two roller table sections can be controlled jointly or independently of one another with regard to the pivoting movement.

Dadurch ist es möglich, bei gleichzeitigem Walzbetrieb In beiden Walzstrassen bzw. Walzlinien, d.h. bei zweiadriger Walzung von dünnen, biegsamen Profilquerschnitten je ein Kühlbett oder bei einadriger Walzung von dicken, relativ biegesteifen Profilquerschnitten in nur einer Walzlinie, dem Haupt- oder Nebenstrang, wechselweise das eine oder das andere Kühlbett mit Teillängen zu beschicken.This makes it possible, with simultaneous rolling operation, in both rolling trains or rolling lines, i.e. with two-core rolling of thin, flexible profile cross sections, one cooling bed each or with single core rolling of thick, relatively rigid profile cross sections in only one rolling line, the main or secondary strand, alternately loading one or the other cooling bed with partial lengths.

Bei dem Einrichten der Auflaufrollgänge auf die andere Walzlinie bei einadrigem Walzbetrieb und wechselnder Bedienung beider Kühlbetten mit Teillängen ergeben sich zwangsläufig Knickstellen in der Walzlinie beim Überleiten des Walzgutes von dem vorgeordneten Rollgang auf den Auflaufrollgang des jeweils anderen Kühlbettes. Dadurch bedingt wird die Laufruhe des Walzgutes, insbesondere der Kopf- und Schwanzenden abhängig von der Fördergeschwindigkeit relativ stark beeinträchtigt, was zu Betriebsstörungen führen kann.When setting up the roller table on the other rolling line with single-core rolling operation and changing operation of both cooling beds with partial lengths, there are inevitably kinks in the rolling line when the rolling stock is transferred from the upstream roller table to the roller table of the other cooling bed. As a result, the smooth running of the rolling stock, in particular the head and tail ends, is relatively severely impaired depending on the conveying speed, which can lead to malfunctions.

Weiter ist es in Anbetracht der grossen zu bewegenden Massen der Schwenkweiche jedoch nur möglich, diese in grösseren Pausenzeiten der aufeinanderfolgenden Teillängen von dem einen Kühlbett auf das der anderen Walzlinie zugeordnete Kühlbett bei einadriger Walzung vorzunehmen, um die Kapazität beider Kühlbetten gleichzeitig und gleichmässig auszunutzen.Furthermore, in view of the large masses of the swivel switch to be moved, it is only possible to do this during longer breaks of the successive partial lengths from one cooling bed to the cooling bed assigned to the other rolling line with single-core rolling, in order to utilize the capacity of both cooling beds simultaneously and evenly.

Durch die FR-PS 1 328 186 ist bereits eine Vorrichtung bekannt, die aus zwei zueinander etwa parallelen Walzlinien besteht. Jede Walzlinie beschickt ein zugeordnetes Kühlbett. Dabei ist ein schwenkbeweglicher Weichenabschnitt vorgesehen, der es ermöglicht, entweder aus beiden Walzlinien gleichzeitig je ein Kühlbett oder aus jeweils einer Walzlinie das der einen oder der anderen Walzlinie zugeordnete Kühlbett zu beschicken. Ein auslenkbarer Rollgangsabschnitt ist jeder Walzlinie vorgeordnet, der kühlbettseitig wahlweise in die eine oder die andere Walzlinie einschwenkbar ist. Die Anordnung hat den Nachteil, dass bei wechselweisem Überleiten der Teillängen aus einer Walzlinie auf das eine oder das andere Kühlbett ausser der vorderen Weiche noch zusätzlich eine Kreuzweiche betätigt werden muss, wodurch sowohl der baulich als auch der steuerungstechnische Aufwand der Einrichtung erheblich erhöht und dadurch die Investitionskosten steigen. Da der vorgeordnete auslenkbare Rollgangsabschnitt für auszulenkendes biegesteifes Walzgut ebenfalls sehr lang sein muss, ergeben sich bei dieser Einrichtung ebenfalls die Nachteile der grossen zu bewegenden Massen, wodurch ein Umsteuern der Einrichtung innerhalb der Folgezeiten der Teillängen in der Praxis nicht zu verwirklichen ist.From FR-PS 1 328 186 a device is already known which consists of two roughly parallel rolling lines. Each rolling line feeds an assigned cooling bed. In this case, a pivotable switch section is provided, which makes it possible to feed either one cooling bed from both rolling lines at the same time or from one rolling line to the cooling bed assigned to one or the other rolling line. A deflectable roller table section is arranged upstream of each rolling line, which can be pivoted into one or the other rolling line on the cooling bed side. The arrangement has the disadvantage that when the partial lengths are alternately transferred from a rolling line to one or the other cooling bed in addition to the front switch, a cross switch also has to be actuated, as a result of which both the structural and the control-related complexity of the device are increased considerably, and thus the Investment costs go up. Since the upstream deflectable roller table section for deflecting rigid rolling stock also has to be very long, this device also has the disadvantages of the large masses to be moved, so that it is not possible in practice to reverse the device within the subsequent times of the partial lengths.

Weiter ist durch die US-PS 3 223 345 eine rohrförmige Schwenkweiche für Walzgut zwischen einem Walzgerüst und zwei wechselweise beschickbaren Haspeln bekannt. Dabei ist die Schwenkweiche an dem walzgerüstseitigen Ende drehbeweglich gelagert, so dass bei Verschwenken des haspelseitigen Endes der Schwenkweiche in Richtung der einen oder anderen Haspelrohrführung das walzgerüstseitige Ende der Schwenkweiche der Auslenkbewegung in horizontaler Ebene folgen kann. Die Schwenkbewegung erfolgt über einen in vertikaler Ebene an der Schwenkweiche befestigten Hebel längs einer in horizontaler Ebene sich erstreckenden Gleitführung des auslaufseitigen Endes der Schwenkweiche. Diese Schwenkweiche wird geradlinig verschwenkt, so dass an der Einlaufseite der Schwenkweiche mit dem Ende der Rohrzuführung eine Knickstelle entsteht, durch die relativ breite, biegesteife Profilquerschnitte nicht ausgelenkt werden können.Furthermore, from US Pat. No. 3,223,345, a tubular swivel switch for rolling stock between a roll stand and two alternately loadable reels is known. The swivel switch is rotatably mounted on the end of the roll stand, so that when the end of the swivel switch is pivoted in the direction of one or the other coiler tube guide, the end of the swivel switch on the roll stand can follow the deflection movement in the horizontal plane. The pivoting movement takes place via a lever attached to the pivoting switch in a vertical plane along a sliding guide of the outlet-side end of the pivoting switch which extends in a horizontal plane. This swivel switch is pivoted in a straight line, so that a kink occurs at the inlet side of the swivel switch at the end of the pipe feed, through which relatively wide, rigid profile cross sections cannot be deflected.

Aufgabe der Erfindung ist es, die Überleitbedingungen für das störungsfreie Überführen der Teillängen auf den schwenkbeweglichen Auflaufrollgang bei einadrigem Betrieb und wechselweiser Belegung beider Kühlbetten.zu verbessern sowie das wechselweise Beschicken auch bei aufeinanderfolgenden Teillängen betriebssicher zu gewährleisten. Weiter soll dabei gleichzeitig aus diesen Gründen ein Anpassen der Förderebene des Zuförderrollganges an die Neigung der Förderebene der schwenkbeweglichen Auflaufrollgänge erfolgen und eine Richtungsänderung des Walzgutes zwischen Zulaufrollgang und schwenkbeweglichem Auflaufrollgang vermieden werden. Schliesslich soll ein kurzer Schwenkweg beim Überwechseln des Zuführrollgangs von einer Walzlinie in die andere erreicht werden, um die Umsteuerung kurzzeitig in den Folgezeiten der aufeinanderfolgenden Teillängen und nicht nur in den durch die Knüppelfolgezeiten bedingten Pausenzeiten vornehmen zu können.The object of the invention is to improve the transfer conditions for the trouble-free transfer of the partial lengths to the swiveling overrun roller table with single-core operation and alternate occupancy of both cooling beds, and to ensure the alternate loading even with successive partial lengths in a reliable manner. Furthermore, for these reasons, the conveying plane of the feed roller table should be adapted to the inclination of the conveying plane of the swiveling roller table and a change in direction of the rolling stock between the inlet roller table and the swiveling roller table should be avoided. Finally, a short swivel path should be achieved when changing the feed roller table from one rolling line to the other in order to briefly change over in the subsequent times of the successive partial lengths and not only in the break times due to the stick following times.

Zur Lösung der gestellten Aufgabe wird vorgeschlagen, dem den Auflaufrollgang bildenden schwenkbeweglichen Weichenabschnitt je Walzlinie einen seitlich zur Förderrichtung auslenkbaren Rollgangsabschnitt vorzuordnen, der kühlbettseitig wahlweise mit dem Kopfende der Auflaufrollgänge fluchtend in die eine oder die andere Walzlinie einschwenkbar ist. Die Auslenkbewegung kann in horizontaler Ebene oder längs einer bogenförmigen Bahn erfolgen. Dabei ist der auslenkbare Rollgangsabschnitt als Kipprollgang ausgebildet, der kühlbettseitig mittels einer seitlich zur Förderrichtung gerichteten Kippbewegung längs einer bogenförmigen Bahn gegenüber seinem einlaufseitigen als Festlager ausgebildeten und ortsfest gehaltenem Ende aus seiner Mittellage unter Verwinden um seine Längsachse und Verschwenken um eine zu dieser längs der Förderrichtung nach unten geneigten Schwenkachse wahlweise mit den Kopfenden der Auflaufrollgänge fluchtend in die eine oder die andere Walzlinie einschwenkbar ist, wobei die Neigung der Förderebene der Auflaufrinnen der Auflaufrollgänge und die Neigung der Förderebene der Auflaufrinnen der vorgeordneten Kipprollgänge in der jeweiligen Betriebsstellung an den jeweiligen Überleitstellen miteinander fluchtend ausgebildet sind.To achieve the object, it is proposed that the pivotable switch section forming the ramp roller table be preceded by a roll table section that can be deflected laterally to the conveying direction and that can be pivoted into the one or the other rolling line in alignment with the head end of the ramp roller tables. The deflection movement can take place in a horizontal plane or along an arcuate path. The deflectable roller table section is designed as a tilting roller table which, on the cooling bed side, by means of a tilting movement directed laterally to the conveying direction along an arcuate path relative to its inlet-side end which is designed as a fixed bearing and is held in a fixed position from its central position by twisting about its longitudinal axis and pivoting about one along the conveying direction the swivel axis inclined at the bottom can optionally be pivoted in alignment with one of the other rolling lines in alignment with the head ends of the ramp roller conveyors, the inclination of the conveying plane of the ramp grooves of the ramp roller conveyors and the inclination of the conveying plane of the ramp channels of the upstream tilting roller conveyors being in alignment with one another at the respective transfer points in the respective operating position are.

Vorteil einer derartigen Einrichtung ist, dass der seitlich auslenkbare Rollgangsabschnitt bzw. der Kipprollgang unter einem geringsten Hubweg sehr schnell in die eine oder die andere Walzlinie des jedem Kühlbett zugeordneten schwenkbeweglichen Auflaufrollgangs bewegt werden kann, so dass die aufeinanderfolgenden Teillängen auch wechselweise dem einen oder anderen Kühlbett zugeführt werden. Dabei werden durch eine Richtungsänderung des Walzgutes bedingte Stossstellen an den Überleitstellen zwischen Zufuhrrollgang und Auflaufrollgang vermieden, so dass das Walzgut ruhig und betriebssicher in die jeweilige Walzlinie geführt wird. Weiter wird erreicht, dass infolge der radialen Kippbewegung des Kipprollganges jeweils die Förderebene des Kipprollgangs bezüglich seiner Neigung fluchtend mit der des zugeordneten schwenkbeweglichen Auflaufrollgangs an der Überleitstelle der jeweiligen Teillänge liegt, wodurch ein ruhiger, betriebssicherer Lauf der Teillängen gewährleistet ist. Schliesslich kann das Umsteuern des Kipprollgangs in die jeweilige Walzlinie bei einer äusserst geringen, kurzhubigen Umsteuerbewegung erfolgen.An advantage of such a device is that the laterally deflectable roller table section or the tilting roller table can be moved very quickly into one or the other rolling line of the pivoting movable roller table assigned to each cooling bed, with the shortest possible stroke, so that the successive partial lengths can alternately alternate between one or the other cooling bed are fed. As a result of a change in the direction of the rolling stock, impact points at the transfer points between the feed roller table and the overrun roller table are avoided, so that the rolling stock is guided calmly and reliably into the respective rolling line. It is also achieved that, due to the radial tilting movement of the tilting roller table, the conveying plane of the tilting roller table is aligned with respect to its inclination with that of the associated pivoting movable roller table at the transfer point of the respective partial length, thereby ensuring a smooth, reliable running of the partial lengths. Finally, the tilting roller table can be reversed into the respective rolling line with an extremely small, short-stroke reversing movement.

Der Neigungswinkel der Auflaufrinnen der schwenkbeweglichen Auflaufrollgänge sowie der Kipprollgänge in der jeweiligen Betriebslage beträgt ca. 10° zur jeweiligen Kühlbettseite hin gegenüber der horizontalen Ebene. Das walzstrassenseitige Ende des Kipprollgangs in der Walzlinie ist in ortsfesten Stützlagern angeordnet. Der Kippweg des Kipprollgangs an seinem kühlbettseitigen Ende zum Einschwenken in die Fluchtlinie des einen oder des anderen Auflaufrollgangs aus der senkrechten Mittellage zur Schwenkachse erfolgt symmetrisch nach beiden Seiten um die Grösse des Auslenkweges zum Kopfende des einen oder des anderen Auflaufrollgangs. Die Walzgutführungen je Walzlinie von der Walzstrasse bis zum Kopfende des Auflaufrollgangs jedes Kühlbettes sind derart aufeinander zulaufend geführt, dass deren Verlängerung jeweils auf die Einlaufführung des Kühlbettes der anderen Walzlinie gerichtet ist. Dadurch werden beim einadrigen Walzen jegliche Stossstellen in der Walzgutführung an den Überleitstellen vermieden. Die Steuerung der Schwenkbewegung der Auflaufrollgänge und/ oder die Auslenkbewegung der Kipprollgänge erfolgt über längs der walzstrassenseitig vorgeordneten Förderrollgänge angeordnete elektrische Fühler, abhängig von den Lücken zwischen den Teillängen durch geschwindigkeits- oder zeitabhängig gesteuerte Verzögerungsmittel mittels hydraulischer od. dgl. Kraftmittel. Die Steuerung kann auch abhängig vom Schnittkommando der Teillängen erfolgen. Der Kipprollgang stützt sich über seine Länge bei horizontaler Förderebene auf in vertikaler Ebene angeordnete Stelzen ab, die längs einer gemeinsamen nach unten geneigten Fluchtlinie die Schwenkachsen der Stelzen miteinander verbindend, seitlich quer zur Förderlinie auslenkbar sind. Die Länge der Stelzen vergrössert sich über die Länge des Kipprollgangs in Förderrichtung stetig derart, dass beim Ausschwenken des Kipprollgangs um den seitlichen Hubweg eine Auslenkbewegung etwa auf dem Umfang eines Kegelmantels erfolgt, dessen Längsachse eine nach unten geneigte, die Achslager der Stelzen miteinander verbindende Fluchtlinie bildet. Die Schwenkachsen der Stelzen (Stützlager) des Kipprollgangs zum Auflaufrollgang hin sind um den Betrag der stetigen Zunahme der Länge der Stelzen stufenweise zur horizontalen Ebene parallel zur Walzlinie in Förderrichtung nach unten längs einer gemeinsamen, nach unten geneigten Fluchtlinie höhenversetzt angeordnet.The angle of inclination of the overrun troughs of the swiveling overrun roller tables and the tilting roller tables in the respective operating position is approx. 10 ° to the respective cooling bed side in relation to the horizontal plane. The end of the tilting roller table on the rolling mill side in the rolling line is arranged in stationary support bearings. The tipping path of the tipping roller table at its end on the cooling bed side for swiveling into the line of alignment of one or the other overrun roller table from the vertical central position to the swivel axis takes place symmetrically on both sides by the size of the deflection path to the head end of one or the other overrun roller table. The rolling stock guides for each rolling line from the rolling train to the head end of the ramp roller table of each cooling bed are guided towards one another in such a way that their extension is directed in each case towards the inlet guide of the cooling bed of the other rolling line. As a result, any joints in the rolling stock guide at the transfer points are avoided in single-core rolling. The control of the swiveling movement of the overrun roller tables and / or the deflection movement of the tilting roller tables takes place via electrical sensors arranged along the conveyor roller tables arranged upstream of the rolling mill, depending on the gaps between the partial lengths by means of deceleration means controlled by speed or time by means of hydraulic or similar force means. The control can also take place depending on the cutting command of the partial lengths. The tilting roller table is supported over its length in the horizontal conveyor plane on stilts arranged in a vertical plane, which connect the pivot axes of the stilts to one another along a common downwardly inclined escape line and can be deflected laterally transversely to the conveyor line. The length of the stilts increases steadily over the length of the tilting roller table in the conveying direction in such a way that when the tilting roller table is pivoted out about the lateral stroke, a deflection movement takes place approximately on the circumference of a conical jacket, the longitudinal axis of which forms a downward inclined alignment line connecting the axle bearings of the stilts . The swivel axes of the stilts (support bearings) of the tilting roller table towards the overrun roller table are gradually offset by the amount of the steady increase in the length of the stilts to the horizontal plane parallel to the rolling line in the conveying direction downwards along a common, downwardly inclined escape line.

Zur wechselweisen Beschickung beider Kühlbetten mit aufeinanderfolgenden Teillängen bei einadrigem Betrieb werden zwei Verfahren zur Betriebsweise der Einrichtung alternativ vorgeschlagen.For alternately loading both cooling beds with successive partial lengths in single-core operation, two methods of operating the device are alternatively proposed.

Bei der einen Betriebsweise der Einrichtung wird bei relativ langem Kipprollgang der schwenkbewegliche Auflaufroligang der anderen Walzlinie vor Betriebsbeginn in die Betriebsstellung präzise an den anderen schwenkbeweglichen Auflaufrollgang heranbewegt, wobei das wechselweise Überleiten der Teillängen auf das eine oder das andere Kühlbett lediglich abhängig von der Fühlersteuerung durch die Auslenkbewegung des Kipprollgangs erfolgt.In one mode of operation of the device, with a relatively long tilting roller table, the pivotable overrun roller track of the other rolling line is moved precisely into the operating position before the start of operation in the operating position, the alternating transfer of the partial lengths to one or the other cooling bed only depending on the sensor control by the Deflection movement of the tilting roller table takes place.

Bei der anderen Betriebsweise der Einrichtung wird bei relativ kurzem Kipprollgang der schwenkbewegliche Auflaufrollgang der anderen Walzlinie vor Betriebsbeginn weitmöglichst an den einen schwenkbeweglichen Auflaufrollgang heranbewegt und zum wechselweisen Überleiten der Teillängen auf das eine oder das andere Kühlbett sowohl durch eine Schwenkbewegung des Kipprollgangs in die Betriebslage als auch eine zu der Betriebslage des Kipprollgangs hin gerichtete zusätzliche relative Schwenkbewegung des Auflaufrollgangs der anderen Walzlinie bei jedem Überleiten einer Teillänge auf den Auflaufrollgang abhängig von der Fühlersteuerung ausgeführt, wobei gleichzeitig ein gleichgerichtetes Ausschwenken des einen Auflaufroligangs um den gleichen Betrag der relativen Schwenkbewegung des anderen Auflaufrollgangs in der gleichen Schwenkrichtung seitlich erfolgt.In the other mode of operation of the device with a relatively short tilting roller table, the swiveling overrun roller table of the other rolling line is moved as far as possible to the one swiveling overrun roller table and for alternate transfer of the partial lengths on one or the other cooling bed both by a pivoting movement of the tilting roller table into the operating position and an additional relative pivoting movement of the other roller line directed towards the operating position of the tilting roller table each time a partial length is transferred to the ramping roller table, depending on the sensor control, at the same time, the same pivoting out of the one overrun roller table by the same amount of the relative pivoting movement of the other overrun roller table takes place laterally in the same pivoting direction.

In den Fig. 1, 3, 4 und 5 sind mit 1 und 1a je ein in zwei etwa parallelen Walzlinien. I und 11 angeordnete Fertigwalzgerüste als Teil einer vorgeordneten Walzstrasse für Feinstahl- und Mittelstahlprofile mit zueinander parallel, jedoch versetzt angeordneten Walzgerüststaffeln bezeichnet Die Walzgerüste sind Duo-Walzgerüste mit Kaliberwalzensätzen, welche abhängig vom Walzprogramm jeweils um 90° zueinander versetzt hintereinander angeordnet sind. Die bauliche Ausbildung der Walzstrasse ist beispielsweise als sogenannte Mehrlinienanordnung oder als Walzstrasse mit zwei etwa parallelen Walzlinien bekannt und gestattet das Walzen eines breiten Walzprogramms sowohl in beiden Walzlinien gleichzeitig oder nur in einer Walzlinie von verschiedensten Profilquerschnitten und Querschnittsabmessungen von biegsamen und relativ biegesteifem Walzgut. Die Profilquerschnitte umfassen im wesentlichen Rundprofile von 8 bis 70 mm 0, Quadratprofile von 8 bis 70 mm Kantenlänge, Sechskant- und Achtkantprofile von 8 bis 70 mm Schlüsselweite, Flachprofile von 12 bis 150 mm Breite, gleichschenkelige Winkelprofile von 16 x 16 mm bis 90 x 90 mm Kantenlänge sowie ungleichschenkelige Winkelprofile von 30 x 20 bis 100 x 70 mm Kantenlänge, U-Profile von 30 x 20 bis 100 x 40 mm, T-Profile von 20 bis 80 mm Höhe sowie Doppel-T-Profile bis 100 mm Breite.1, 3, 4 and 5 with 1 and 1a are each one in two approximately parallel rolling lines. I and 11 arranged finishing stands as part of an upstream rolling mill for fine steel and medium steel profiles with parallel but offset staggered mill stands.The rolling stands are duo-mill stands with caliber roll sets, which are arranged one behind the other by 90 ° depending on the rolling program. The structural design of the rolling mill is known, for example, as a so-called multi-line arrangement or as a rolling mill with two roughly parallel rolling lines and allows the rolling of a wide rolling program in both rolling lines simultaneously or only in one rolling line of different profile cross-sections and cross-sectional dimensions of flexible and relatively rigid rolling stock. The profile cross-sections essentially include round profiles from 8 to 70 mm 0, square profiles from 8 to 70 mm edge length, hexagonal and octagonal profiles from 8 to 70 mm width across flats, flat profiles from 12 to 150 mm width, isosceles angle profiles from 16 x 16 mm to 90 x 90 mm edge length and unequal leg angle profiles from 30 x 20 to 100 x 70 mm edge length, U-profiles from 30 x 20 to 100 x 40 mm, T-profiles from 20 to 80 mm high and double-T profiles up to 100 mm wide.

Für dünnere, biegsame Profilquerschnitte ist eine sogenannte zweiadrige Walzung gleichzeitig in den Walzlinien I und II auf je ein zugeordnetes Kühlbett 16 bzw. 16a und für dickere, relativ biegesteife Profilquerschnitte eine einadrige Walzung in der Walzlinie oder der Walzlinie 11 möglich, wobei ebenfalls wechselweise beide Kühlbetten mit Teillängen beschickt werden.For thinner, flexible profile cross-sections, a so-called two-core rolling is simultaneously carried out in the rolling lines I and II on an associated cooling bed 16 or 16a, and for thicker, relatively rigid profile cross-sections, a single-core rolling in the rolling line or the rolling line 11 is possible, both cooling beds also alternatingly possible be loaded with partial lengths.

Den Fertigwalzgerüsten 1, 1a der vorgeordneten Walzstrasse ist je eine rotierende Schopf-und Teilschere 2, 2a in Förderrollgängen 3, 3a zugeordnet. Die Teilscheren 2, 2a schopfen den Walzgutstrang und unterteilen diesen in kühlbettgerechte Teillängen. An die Förderrollgänge 3, 3a schliesst sich in den Walzlinien und 11 je ein relativ kurzer Kipprollgang 5, 5a an, dessen Länge je nach Kühlbettlänge und max. Walzgeschwindigkeit ca. 10 bis 20 m beträgt.A rotating cropping and section shear 2, 2a in conveyor roller tables 3, 3a is assigned to the finishing stands 1, 1a of the upstream rolling mill. The part shears 2, 2a scoop the strand of rolled material and divide it into partial lengths suitable for cooling beds. The conveyor roller tables 3, 3a are followed in the rolling lines and 11 by a relatively short tilting roller table 5, 5a, the length of which depends on the length of the cooling bed and max. Rolling speed is about 10 to 20 m.

Wie die Fig. 3 und 4 zeigen, ist der Kipprollgang 5, 5a an der Einlaufseite der Teillängen auf einem Festlager 7 befestigt und stützt sich über seine Länge auf Stelzen 8 ab, die um in horizontaler Ebene angeordnete Drehachsen 10 schwenkbeweglich sind. Die Stelzen 8 haben in Förderrichtung R eine stetig zunehmende Länge, wodurch die Stützlager 11 der in horizontaler Ebene liegenden Drehachsen 10 stufenförmig nach unten höhenversetzt längs einer gemeinsamen geneigt verlaufenden Fluchtlinie A als Schwenkachse in vertikaler Ebene angeordnet sind. Der Kipprollgang 5, 5a ist mittels eines an seinem ausiaufseitigen Ende angeordneten hydraulischen oder pneumatischen Kraftmittels 12, 12a, dessen Kolbenstangen 13, 13a an den Kipprollgang 5, 5a angelenkt sind, nach beiden Seiten aus seiner senkrechten Mittellage in die Betriebsstellungen B, bzw. B2 schwenkbeweglich. Dabei erfolgt die Schwenkbewegung auf einer bogenförmigen Bahn etwa längs des Umfanges eines mit seiner Längsachse in der Fluchtlinie A geneigt liegenden Kegelmantels, die sich, wie nicht weiter dargestellt, auch unterhalb des Festlagers 7 fortsetzen kann, wodurch der Kipprollgang 5, 5a unter Verwinden von seinem Festlager 7 aus seitlich in die jeweilige Walzlinie ausgelenkt wird. Durch das Verschwenken des Kipprollgangs 5 bzw. 5a mit seinem auslaufseitigen Ende in die Endstellung B, oder B2 erfolgt bei einadrigem Walzbetrieb wechselweise ein Überleiten der aufeinanderfolgenden Teillängen entweder in den schwenkbeweglichen Auflaufrollgang 15 mit nachgeordnetem Kühlbett 16 oder in den schwenkbeweglichen Auflaufrollgang 15a mit nachgeordnetem Kühlbett 16a. Die Kipprollgänge 5,5a sowie die Auflaufrollgänge 15, 15a haben ebenso wie die übrigen Förderrollgänge 3, 3a Rollgangsrollen mit Einzelantrieb, jedoch sind die Antriebe der Kipprollgänge 5, 5a und die der Auflaufrollgänge 15, 15a zueinander versetzt angeordnet, um die Rollgänge möglichst dicht aneinander heranfahren zu können. Wie in den Fig. 1 und 5 dargestellt, stützen sich die schwenkbeweglichen Auflaufrollgänge 15, 15a auf Verfahrbahnen 18 über Rollen 19 ab und sind unabhängig voneinander oder gemeinsam über hydraulische oder pneumatische Kraftmittel 20, 20a um einen Schwenkpunkt S seitlich zu der Walzlinie auf Rollen 19 längs Verfahrbahnen 18 bewegbar. Die Kolbenstangen 21, 21a der Kraftmittel 20, 20a sind dazu über Verschiebegestänge 22 und an den Längsseiten der Auflaufrollgänge 15, 15a beispielsweise angelenkte Winkelhebel 23 mit zu den Kühlbetten 16, 16a hin abnehmenden Längenabmessungen über Zuggestänge 24 an den Auflaufrollgängen 15, 15a angelenkt. An die Auflaufrollgänge 15, 15a schliessen sich seitlich der Walzlinie I und II Kühlbetten 16, 16a an.3 and 4 show, the tilting roller table 5, 5a is attached to a fixed bearing 7 on the inlet side of the partial lengths and is supported over its length on stilts 8 which are pivotable about axes of rotation 10 arranged in a horizontal plane. The stilts 8 have a continuously increasing length in the conveying direction R, as a result of which the support bearings 11 of the axes of rotation 10 lying in the horizontal plane are offset in height downwards along a common inclined escape line A as a pivot axis in the vertical plane. The tilting roller table 5, 5a is moved by means of a hydraulic or pneumatic power means 12, 12a arranged on its outside end, the piston rods 13, 13a of which are articulated to the tilting roller table 5, 5a, from its vertical central position into the operating positions B and B respectively 2 swiveling. The swiveling movement takes place on an arcuate path approximately along the circumference of a conical shell which is inclined with its longitudinal axis in the alignment line A, which, as not shown further, can also continue below the fixed bearing 7, as a result of which the tilting roller table 5, 5a twists its Fixed bearing 7 is laterally deflected into the respective rolling line. By pivoting the tilting roller table 5 or 5a with its outlet-side end into the end position B, or B 2 , in the case of single-core rolling operation, the successive partial lengths are alternately transferred either to the pivoting roller table 15 with a cooling bed 16 or to the pivoting roller table 15a with a cooling bed 16a. The tilting roller tables 5,5a as well as the ramp roller tables 15, 15a, like the other conveyor roller tables 3, 3a, have roller table rollers with individual drives, however the drives of the tilt roller tables 5, 5a and those of the ramp roller tables 15, 15a are arranged offset to one another in order to bring the roller tables as close together as possible to be able to drive up. As shown in FIGS. 1 and 5, the swiveling run-up roller tables 15, 15a are supported on travel paths 18 via rollers 19 and are independent of one another or together via hydraulic or pneumatic force means 20, 20a Pivot point S can be moved laterally to the rolling line on rollers 19 along travel paths 18. For this purpose, the piston rods 21, 21a of the force means 20, 20a are articulated via displacement linkages 22 and on the longitudinal sides of the roller roller tables 15, 15a, for example articulated angle levers 23 with decreasing length dimensions toward the cooling beds 16, 16a, via pull rods 24 on the roller roller tables 15, 15a. Cooling beds 16, 16a adjoin the run-up roller tables 15, 15a to the side of the rolling line I and II.

Die Auflaufrollgänge 15, 15a sind in üblicher Weise mit festen Rinnenabschnitten und Trenn-und Bremsmitteln versehen und kühlbettseitig um vertikale Schwenkachsen S schwenkbeweglich. Die Neigung der Auflaufrinnen der Auflaufrollgänge bzw. die Neigung der Förderebene bzw. der Rollgangsachsen beträgt etwa 10°, welche in den Betriebsstellungen B, und B2 mit der Neigung der Auflaufrinnen der Kipprollgänge 5, 5a; 25, 25a fluchtet und damit ein stossstellenfreies Überleiten der Teillängen ermöglicht.The run-up roller tables 15, 15a are provided in the usual way with fixed channel sections and separating and braking means and can be pivoted about vertical pivot axes S on the cooling bed side. The inclination of the run-up channels of the run-up roller tables or the inclination of the conveying plane or the roller table axes is approximately 10 °, which in the operating positions B and B 2 corresponds to the inclination of the run-up channels of the tilting roller tables 5, 5a; 25, 25a is aligned and thus enables a joint-free transfer of the partial lengths.

Die Fig. 2 stellt die Anordnung nach Fig: 1 im Ausschnitt mit relativ langem Kipprollgang 25, 25a dar, bei welcher der Kipprollgang abhängig von der Kühlbettlänge und der Walzgeschwindigkeit eine Länge von ca. 40 bis 60 m aufweist.2 shows the arrangement according to FIG. 1 in a detail with a relatively long tilting roller table 25, 25a, in which the tilting roller table has a length of approximately 40 to 60 m, depending on the length of the cooling bed and the rolling speed.

Die Betriebsweise für zweiadrigen Walzbetrieb zum Überleiten von aufeinanderfolgenden Teillängen dünner biegsamer Profilquerschnitte aus den Walzlinien I und II erfolgt je von den Walzgerüsten 1 über den Förderrollgang 3, den Kipprollgang 5, den Auflaufrollgang 15 auf das Kühlbett 16 bzw. von dem Walzgerüst 1a über den Förderrollgang 3a, den Kipprollgang 5a, den Auflaufrollgang 15a auf das Kühlbett 16a, wie in den Fig. 1 und 6 dargestellt.The operating mode for two-wire rolling operation for transferring successive partial lengths of thin, flexible profile cross sections from the rolling lines I and II takes place from the rolling stands 1 via the conveyor roller table 3, the tilting roller table 5, the ramp roller table 15 onto the cooling bed 16 or from the rolling stand 1a via the conveyor roller table 3a, the tilting roller table 5a, the overrun roller table 15a onto the cooling bed 16a, as shown in FIGS. 1 and 6.

Die Fig. 7 zeigt in der Draufsicht schematisch die Betriebsweise der Anlage für einadrigen Walzbetrieb von dickeren, relativ biegesteifen Profilquerschnitten, beispielsweise in der Walzlinie I, bei relativ kurzem Kipprollgang 5. Der Kipprollgang 5 sowie die Auflaufrollgänge 15, 15a sind in ihren verschiedenen Betriebslagen durch ausgezogene bzw. gestrichelte Linien 1, II bzw. la, IIa vereinfacht dargestellt. Mit 16, 16a sind die Kühlbetten bezeichnet. Die Winkel a, und β deuten die Auslenkwinkel des Kipprollgangs 5 bzw. der Auflaufrollgänge 15 bzw. 15a an.Fig. 7 shows a top view schematically of the operation of the system for single-core rolling operation of thick, relatively rigid profile cross sections, for example in the rolling line I, with a relatively short tilt roller table 5. The tilt roller table 5 and the ramp roller tables 15, 15a are in their different operating positions solid or dashed lines 1, II and la, IIa shown in simplified form. The cooling beds are designated 16, 16a. The angles a and β indicate the deflection angles of the tilting roller table 5 and the ramp roller tables 15 and 15a.

Die Teillängen passieren in der Walzlinie I längs der Förderrichtung R den Förderrollgang 3 und den Kipprollgang 5, der wechselweise nach jeder aufeinanderfolgenden Teillänge oder der aus einem Anstichknüppel bestehenden Anzahl von Teillängen um den Winkel a1 entweder in die Betriebsstellung B1 oder B2 (gestrichelt bzw. ausgezogen dargestellt) seitlich verschwenkt wird. Der schwenkbewegliche Auflaufrollgang 15 ist gegenüber der Fig. 6 ebenso wie der schwenkbewegliche Auflaufrollgang 15a vor Betriebsbeginn des einadrigen Walzbetriebs im Ausführungsbeispiel in der Walzlinie I in den Nahbereich des Schwenkwinkels a, des Kipprollgangs 5 verschoben worden, so dass das Überleiten der aufeinanderfolgenden Teillängen entweder auf das Kühlbett 16 oder das Kühlbett 16a durch eine zusätzliche relative Schwenkbewegung um den Winkel β der Auflaufrollgänge 15, 15a gleichzeitig mit dem Umsteuern des Kipprollgangs 5 um den Winkel α1 zum Überleiten der Teillängen entweder über die Walzlinie I auf das Kühlbett 16 oder über die Walzlinie Ila auf das Kühlbett 16a erfolgen kann. Um ein möglichst enges Zusammenschieben der Auflaufrollgänge 15 und 15a zu ermöglichen, sind, wie bereits beschrieben und in den Fig. 1 und 2 dargestellt, die Antriebsmotoren versetzt zueinander angeordnet. Bei jeder relativen Schwenkbewegung des einen Auflaufrollgangs 15 wird ebenfalls der andere Auflaufrollgang 15a um den gleichen Winkel β, d. h. um den gleichen Betrag in der gleichen Schwenkrichtung mit verschoben.The partial lengths pass in the rolling line I along the conveying direction R the conveyor roller table 3 and the tilting roller table 5, which alternately after each successive partial length or the number of partial lengths consisting of a tapping stick by the angle a 1 either in the operating position B 1 or B 2 (dashed lines or shown in full) is pivoted sideways. 6, like the pivotable roller roller table 15a before the start of operation of the single-core rolling operation in the exemplary embodiment in the rolling line I, has been shifted into the vicinity of the pivoting angle a, the tilting roller table 5, so that the transfer of the successive partial lengths either to that Cooling bed 16 or the cooling bed 16a by an additional relative pivoting movement by the angle β of the ramp roller tables 15, 15a simultaneously with the reversal of the tilting roller table 5 by the angle α 1 for transferring the partial lengths either over the rolling line I to the cooling bed 16 or over the rolling line Ila can take place on the cooling bed 16a. In order to enable the run-up roller tables 15 and 15a to be pushed together as tightly as possible, the drive motors are, as already described and shown in FIGS. 1 and 2, offset from one another. With each relative pivoting movement of the one overrun roller table 15, the other overrun roller table 15a is also displaced by the same angle β, ie by the same amount in the same pivoting direction.

Die Steuerung der Verschiebeantriebe 12, 20 bzw. 12a, 20a erfolgt durch eine die Lücke zwischen den Teillängen abtastende Fotozelle F über ein zeit- oder laufgeschwindigkeitsabhängiges Verzögerungsglied V durch gleichzeitiges Betätigen der Verschiebeantriebe 12, 12a, 20a, 20 (für einadrigen Walzbetrieb in der Walzlinie Il) und wechselweises Beschicken beider Kühlbetten 16, 16a mitTeillängen. Bei einadrigem Walzbetrieb in der Walzlinie II wird in gleicher Weise sinngemäss der Kipprollgang 5a gemeinsam mit den Auflaufrollgängen 15, 15a betätigt.The displacement drives 12, 20 and 12a, 20a are controlled by a photo cell F which scans the gap between the partial lengths via a delay element V which is dependent on time or running speed by simultaneously actuating the displacement drives 12, 12a, 20a, 20 (for single-core rolling operation in the rolling line Il) and alternately loading both cooling beds 16, 16a with partial lengths. In the case of a single-core rolling operation in the rolling line II, the tilting roller table 5a is actuated in the same way, together with the ramp roller tables 15, 15a.

In der Fig. 8 ist in der Draufsicht schematisch die Betriebsweise der Anlage für einadrigen Walzbetrieb von dickeren, relativ biegesteifen Profilquerschnitten beispielsweise in der Walzlinie II bei relativ langem Kipprollgang 25, 25a nach Fig. 2 dargestellt.FIG. 8 shows a schematic top view of the operation of the system for single-core rolling operation of thicker, relatively rigid profile cross sections, for example in the rolling line II with a relatively long tilting roller table 25, 25a according to FIG. 2.

Die Teillängen werden beispielsweise in der Walzlinie II über den Förderrollgang 3a und den Kipprollgang 25a, der um den Schwenkwinkel α2 wechselweise in die eine oder andere Betriebslage B, bzw. B2 in der Zeit zwischen den aufeinanderfolgenden Teillängen umsteuerbar ist, in vorgeschriebener Weise umgesteuert. Da die Auflaufrollgänge 15, 15a bereits vor Betriebsbeginn in die Positionen II bzw. la bewegt worden sind, entfällt hier die in Fig. 7 beschriebene zusätzliche relative Schwenkbewegung der Auflaufrollgänge 15, 15a, da deren Abstand bereits dem Schwenkweg des Kipprollgangs 25a entspricht. Somit kann hierbei wechselweise eine Teillänge über die Walzlinie la des Auflaufrollgangs 15 und die nachfolgende über die Walzlinie II des Auflaufrollgangs 15a dem Kühlbett 16 bzw. 16a zugeführt werden. Von der Fotozellensteuerung F wird hierbei lediglich der Verschiebeantrieb 12a des Kipprollgangs 25a betätigt. Das sanfte Überleiten der Teillängen von dem Kipprollgang 25a in die Walzlinie la sorgt für einen ruhigen störungsfreien Betrieb.The partial lengths are reversed in the prescribed manner, for example, in the rolling line II via the conveyor roller table 3a and the tilting roller table 25a, which can alternately be switched to one or the other operating position B or B 2 in the time between the successive partial lengths by the pivoting angle α 2 . Since the caster roller tables 15, 15a had already been moved into the positions II or la before the start of operation, the additional relative pivoting movement of the caster roller tables 15, 15a described in FIG. 7 is omitted here, since their distance already corresponds to the pivoting path of the tilting roller table 25a. Thus, a partial length can alternately be fed to the cooling bed 16 or 16a over the rolling line 1 a of the overrun roller table 15 and the subsequent one over the rolling line II of the overrun roller table 15a. In this case, only the displacement drive 12a of the tilting roller table 25a is actuated by the photocell control F. The gentle transfer of the partial lengths from the tilting roller table 25a into the rolling line la ensures quiet, trouble-free operation.

Sinngemäss können in entsprechender Weise bei einadriger Walzung in der Walzlinie I wechselweise die Teillängen auf das Kühlbett 16 oder 16a übergeführt werden.Analogously, in the case of single-core rolling in the rolling line I, the partial lengths can alternately be transferred to the cooling bed 16 or 16a.

Der Schwenkweg der Kipprollgänge 5, 5a und 25, 25a in die Betriebslage B, oder B2 ist so bemessen, dass jeweils die Neigung der Auflaufrinnen bzw. der Förderebenen an den Übergangsstellen zu den Schwenkrollgängen 15, 15a mit der Neigung der Auflaufrinnen bzw. der Förderebene mit ca. 10° gleich gross ist, so dass die Förderebenen auch bezüglich ihrer Neigungswinkel miteinander fluchten. Dadurch wird eine sichere Führung der Teillängen bei grosser Laufruhe an den Übergangsstellen gewährleistet.The swivel path of the tilting roller tables 5, 5a and 25, 25a into the operating position B or B 2 is dimensioned such that the inclination of the runways or the conveying levels at the transition to the swivel roller tables 15, 15a with the inclination of the run-up channels or the conveying plane is approximately the same size, so that the conveying planes are also aligned with one another with regard to their inclination angles. This ensures a safe guidance of the partial lengths with great smoothness at the transition points.

Wie insbesondere aus den Fig. 1, 2, 6, 7 und 8 zu ersehen ist, sind die Walzgutführungen in den einzelnen Rollgangsabschnitten 3, 3a; 5, 5a bzw. 25, 25a je Walzlinie von der Walzstrasse bis zum Kopfende der Auflaufroligänge 15, 15a jedes Kühlbettes 16, 16a derart aufeinander zulaufend geführt, dass deren Verlängerung IIa bzw. la jeweils auf die Einlaufführung des Kühlbettes 16a bzw. 16 der anderen Walzlinie gerichtet ist. Dadurch werden auch insbesondere bei dem einadrigen Walzbetrieb für dickere biegesteife Profilquerschnitte jegliche Stossstellen in der Walzgutführung der Teillängen zum wechselweisen Überleiten auf das eine oder das andere Kühlbett vermieden.As can be seen in particular from FIGS. 1, 2, 6, 7 and 8, the rolling stock guides in the individual roller table sections 3, 3a; 5, 5a and 25, 25a per rolling line from the rolling mill to the head end of the run-on roller ways 15, 15a of each cooling bed 16, 16a so that they extend towards one another in such a way that their extension IIa or la respectively leads to the inlet guide of the cooling bed 16a or 16 of the other Rolling line is directed. In this way, especially in the single-core rolling operation for thicker, rigid profile cross-sections, any joints in the rolling of the partial lengths for alternate transfer to one or the other cooling bed are avoided.

Die Ausbildung des auslenkbaren Roligangsabschnittes als Kipprollgang ist als bevorzugtes Ausführungsbeispiel dargestellt und beschrieben. Jedoch kann der seitlich zur Förderrichtung auslenkbare Rollgangsabschnitt auch als in horizontaler Ebene schwenkbeweglicher Rollgang ausgebildet werden, der um eine vertikale Drehachse in die Betriebsstellungen B, bzw. B2 mit den jeweiligen Kopfenden der Auflaufrollgänge 15, 15a fluchtend in sinngemässer Weise nach der Beschreibung mittels der gleichen Steuerung einschwenkbar ist.The design of the deflectable roller gang section as a tilting roller table is shown and described as a preferred exemplary embodiment. However, the laterally deflectable to the conveying direction roller path section can also be formed as in a horizontal plane pivotably movable roller table, about a vertical axis of rotation in the operating positions B, and B 2 with the respective tip ends of the winding roller tables 15, 15a aligned in analogous manner as described by means of the same control can be swiveled.
