Abstract
Description
Die Erfindung betrifft eine Auflauf- und Abbremsvorrichtung, insbesondere für Mittelstahl-Walzprofile, mit einem Einlaufrollgang und einer dazu in paralleler Zuordnung seitlich versetzt angeordneten Bremsvorrichtung, die im Zusammenwirken ein Auflauf- und Bremssystem bilden.The invention relates to an overrun and braking device, especially for medium steel rolled sections, with a Infeed roller table and one in parallel assignment laterally offset braking device which in Working together form an overrun and braking system.
Die Entwicklung von Walzwerken führte in kurzen Zeitabständen jeweils zu höheren Walzgeschwindigkeiten. Dies hatte zur Folge, daß in den Adjustagen steigende Mengen an Walzgut anfielen, und wenn dabei die Aufnahmefähigkeit der Adjustagen mit der Walzkapazität nicht Schritt halten konnte, bildeten diese einen Engpaß für den gesamten Materialfluß. Daraus ergab sich die Forderung, die Adjustagen derart weiterzuentwickeln und anzupassen, daß eine immer größer werdende Walzproduktion On-line versorgt werden konnte, mit der Tendenz nach rationelleren Lösungen, um durch verbesserte Automatisierung die Kapazität zu erhöhen und zugleich den vergleichsweise hohen Aufwand an Personal zu verringern.The development of rolling mills led in short time intervals each at higher rolling speeds. This had to Consequence that increasing amounts of rolling stock in the finishing areas and if the absorption capacity of the finishing areas could not keep up with the rolling capacity this is a bottleneck for the entire material flow. As a result there is a demand to develop the finishing shops in this way and adapt that an ever increasing rolling production Could be supplied on-line, with the tendency more rational solutions to through improved automation to increase the capacity and at the same time the comparative reduce the amount of personnel involved.
Dabei geht es vorrangig um eine höhere Geschwindigkeit des gesamten Materialflusses und um Mittel und Maßnahmen zur geordneten Ablage von Walzgutstäben in angepaßten Kühlbettlängen. Von besonderer Wichtigkeit ist dabei eine positionsgenaue Ablage einzelner Walzstäbe, sei es, daß sie in vorgegebenen Schnittlängen mit jeweils einer Anzahl von Handelslängen paketweise kopfseitig oder fußseitig bündig auf dem Kühlbett zu liegen kommen. Um dies zu erreichen, sind üblicherweise zwischen dem Auslauf eines Walzwerkes und dem Einlauf eines Kühlbettes steuerbare vollautomatische Auflauf- und Abbremsvorrichtungen erforderlich.It is primarily about a higher speed of the entire material flow and about means and measures for orderly storage of rolled stock in adapted Cooling bed lengths. One is of particular importance precise storage of individual rolled bars, be it that they are in predetermined cutting lengths, each with a number of Trading lengths are flush in packets on the head or foot side come to rest on the cooling bed. To achieve this are usually between the outlet of a rolling mill and the Inlet of a cooling bed controllable fully automatic casserole and Braking devices required.
Eine derartige Einrichtung ist beispielsweise aus der DE-OS 2 218 041 bekannt. Daraus geht hervor, daß ein aus der Walzstraße auslaufender Walzstab zunächst eine Trennvorrichtung zum Schopfen der unbrauchbaren Kopfstücke des Walzstabes passiert und danach auf einen Auflaufrollgang gelangt. Darin wird ein einseitig hebbarer Bremsrollgang aktiviert und die Bremsung des sich in Bewegung befindlichen Stabes eingeleitet. Ein solcher Bremsrollgang besteht bei der bekannten Anlage aus mit leichter Schräglage zur Walzachse angeordneten Transportrollen, die den Walzstab über die gesamte Länge zur Kühlbettseite versetzen. Sobald der Walzstab seitlich aus dem Bereich des Auflaufrollganges auf den Abbremsrollgang gelangt, wird dieser abgesenkt und der Auflaufrollgang ist für die Aufnahme eines neuen Walzstabes wieder frei. Der Bremsrollgang wird je nach Profilart des Walzstabes so gesteuert, daß ein Schopfen des Stabkopfes in der Trennvorrichtung in einer vorbestimmten Länge erfolgen kann, oder bei nicht zu schopfenden Walzstäben eine vor der Trennvorrichtung liegende Endstellung erreicht wird. Falls die Walzstäbe gerichtet werden sollen, passieren sie eine Richtmaschine und werden anschließend über den Auslaufrollgang dem Kühlbett, zugeführt. Bei der bekannten Anlage ist gemäß Figur 1 parallel zum Auslaufrollgang die Bremsvorrichtung in Form eines Bremsrollganges angeordnet. Such a device is for example from DE-OS 2 218 041 known. It follows that one from the Rolling rod running out of rolling mill first one Separating device for cropping the unusable head pieces of the Passed through the rolling rod and then on a ramp roller table reached. There is a brake roller table that can be lifted on one side activated and the braking of the moving Initiated. Such a brake roller table exists at known system from with a slight inclination to the rolling axis arranged transport rollers that the rolling rod over the Move the entire length to the cooling bed side. Once the roller bar laterally from the area of the overrun roller table onto the Deceleration roller table, it is lowered and the Overrun roller table is for the admission of a new rolling rod free again. The brake roller table is depending on the profile type of the Rolling rod controlled so that a cropping of the rod head in the separation device in a predetermined length can, or one in front of the Separating device lying end position is reached. if the Rolling rods are to be straightened, they pass one Straightening machine and are then over the outlet roller table the cooling bed. In the known system is according to Figure 1 parallel to the runout roller table, the braking device in Form arranged a brake roller table.
Aus der DE-C-400119 ist ein Zuführrollgang für Kühlbetten mit senkbaren Rollen für die Abbremsung von Stäben bekannt, mit einem zwischen den Rollen liegenden Plattenbelag. Dieser Plattenbelag ist durch eine oder mehrere Wände in zwei oder mehrere Längsabteilungen mit verschiedenen Tiefen geteilt. Der von der Walze kommende Stab wird durch die etwas schief zur Förderrichtung gelagerten Rollen auf die Kühlbettseite geführt. Durch schiefes oder horizontales Absenken der Rollen wird der auf den Rollen befindliche Stab langsam auf dem Plattenbelag abgelegt und dabei abgebremst. Da der Plattenbelag unterschiedlich tiefe Längsabteilungen aufweist, in die auch bei abgesenkten Rollen diese noch wirksam vorstehen, kann ein neuer Stab in diesen tiefen Längsabteilungen durch die Rollen weitergeführt, von den Rollen dann angehoben und durch ihre Schiefstellung gleichfalls zur Kühlbettseite geführt und dann dort wieder abgesenkt werden.From DE-C-400119 is a feed roller table for cooling beds with lowerable Rollers known for braking bars, with one between the Roll lying slab. This slab is covered by a or several walls in two or more longitudinal sections with different Shared depths. The rod coming from the roller becomes something Rollers mounted at an angle to the conveying direction are guided to the cooling bed side. If the rollers are lowered obliquely or horizontally, the roller is opened the rod located on the rollers is slowly placed on the plate surface and slowed down. Because the slab flooring has different depths has, in which these are still effective even with lowered roles project a new staff in these deep longitudinal departments the roles continued, then raised from the roles and through theirs Misalignment also led to the cooling bed side and then there again be lowered.
Nachteilig ist bei den beschriebenen bekannten Vorrichtungen die langsame und nur durch Schräglage der Rollen herbeigeführte ungesteuerte Querförderung des Walzgutes zur Kühlbettseite, was der gewünschten Erhöhung der Geschwindigkeit des Materialflusses entgegensteht. A disadvantage of the known devices described is that they are slow and only uncontrolled cross-conveying caused by the inclined position of the rollers of the rolling stock to the cooling bed side, which is the desired increase in Material flow speed.
Andere bekannte Lösungen für die Gestaltung eines Auflaufbereiches im Zusammenwirken mit Abbremsvorrichtungen können auch mit Anordnungen von Bremsschiebern innerhalb eines Rollganges oder von Abwischern zum seitlichen Abwischen von Walzprofilen in Form einer Abwurfbewegung in die Seitenwand ausgebildet sein.Other known solutions for designing a Overrun area in cooperation with braking devices can also be used with arrangements of brake valves within a Roller table or wipers for wiping the sides Rolled profiles in the form of a discharge movement into the side wall be trained.
Dabei haben Bremsschieber den Nachteil, daß bei vergleichsweise geringen Walzgeschwindigkeiten keine schnelle und sichere Querbewegung auf den sich hebenden Bremsschiebern erfolgt. Andererseits ergibt sich bei Verwendung von Abwischern der Nachteil, daß Zugstangen zur gemeinsamen Schwenkbewegung der Abwischer, die thermisch bedingten Längenänderungen unterworfen sind, zu unerwünschten Schwenkbewegungen führen können. Darüber hinaus kann ein abruptes seitliches Abwischen und die dadurch bedingte unsanfte Auswurfbewegung in die Seitenwand zu Deformationen besonders bei dünnwandigen Doppel-T-Profilen führen.Brake sliders have the disadvantage that at comparatively low rolling speeds no fast and safe lateral movement on the lifting brake slides he follows. On the other hand, when using Wiping down the disadvantage that tie rods become common Swiveling movement of the wipers that are thermally induced Length changes are subject to undesirable Can cause swiveling movements. In addition, a abrupt side wiping and the resulting Rough ejection movement in the side wall to deformation lead especially with thin-walled double-T profiles.
Der Erfindung liegt die Aufgabe zugrunde, eine wesentlich verbesserte Auflauf- und Abbremsvorrichtung anzugeben, welche eine sichere und schnelle Querförderung von Walzprofilen aus dem Einlaufbereich in den Bremsbereich unter Vermeidung der vorgenannten Nachteile und Schwierigkeiten ermöglicht. Die Vorrichtung soll unkompliziert sein und insbesondere eine pflegliche Walzgutbehandlung ohne Profil-Deformationen sicher gewährleisten.The invention is based, an essential task to provide improved overrun and braking device, which a safe and quick cross-feed of rolled sections the entry area into the braking area while avoiding the allows the aforementioned disadvantages and difficulties. The Device should be straightforward, and in particular one Careful treatment of rolling stock without profile deformations guarantee.
Zur Lösung der Aufgabe wird bei einer Auflauf- und
Abbremsvorrichtung der im Oberbegriff von Anspruch 1 genannten
Art eine Ausgestaltung entsprechend dem Kennzeichnungsteil von
Anspruch 1 vorgeschlagen.To solve the problem with a casserole and
Braking device mentioned in the preamble of
Dadurch, daß die Auflauf- und Abbremsvorrichtung erfindungsgemäß als eine zusammenwirkende Funktionseinheit bestehend aus einem Einlaufrollgang mit einem Hubboden mit dessen Ebene überragenden Transportrollen sowie aus einer parallel zugeordneten fest angeordneten Bremsrinne gebildet wird, wobei der Einlaufrollgang zusammen mit Hubboden und Transportrollen um einen seitlich dazu versenkten Schwenkpunkt in eine gegen die Bremsrinne zu schräg-abfallende Neigung aufschwenkbar ist, wird unabhängig von den vorhandenen Walzgeschwindigkeiten eine schnelle und sichere Querbewegung auf der Transportebene der aufschwenkbaren Transportrollen erreicht.The fact that the overrun and braking device according to the invention as a cooperating functional unit consisting of an infeed roller table with a lifting floor whose level is dominated by transport rollers and from a parallel assigned fixed brake trough formed is, the infeed roller table together with lifting floor and Transport rollers around a pivot point sunk to the side in an incline that slopes towards the brake trough can be swung open, becomes independent of the existing one Rolling speeds a quick and safe transverse movement on the transport level of the swiveling transport rollers reached.
Die am Hubboden gelagerten Rollen werden nach Einlaufen eines Profils gemeinsam mit dem Boden angehoben, wodurch nach Erreichen der oberen Hubstellung infolge der Schräglage des Systems ein leichtes und schnelles Querfördern des Walzgutes ermöglicht wird. Dabei rutscht ein Walzprofil auf den leicht geschränkten, sich drehenden Rollen ohne Gefahr einer Deformation quer zur Transportrichtung in den Bremsbereich und wird auf diesem nach Absenken der Rollen in zeitlicher Kontrolle ohne Gefahr einer Deformation zügig abgebremst.The rollers stored on the lifting floor become one after running in Profiles raised together with the floor, causing after Reaching the upper stroke position due to the inclined position of the Systems easy and quick cross-conveying of the rolled stock is made possible. A rolled profile slides easily onto it set, rotating roles without risk of a Deformation transverse to the direction of transport in the braking area and is on this after lowering the roles in time Control braked quickly without risk of deformation.
Infolge des Verzichtes auf die Anordnung von Wischern wird der Anlagenteil der Auflauf- und Abbremsvorrichtung signifikant vereinfacht. Durch Vermeidung des abrupten seitlichen Abwischens und der daraus folgenden unsanften Auswurfbewegung in die Seitenwand werden Deformationen insbesondere der dünnwandigen Doppel-T-Walzprofile mit Vorteil vermieden. As a result of dispensing with the arrangement of wipers, the Plant part of the overrun and braking device significant simplified. By avoiding the abrupt side Wiping and the resulting rough ejection movement deformations in particular of the thin-walled double T rolled profiles advantageously avoided.
Eine erfindungswesentliche Ausgestaltung sieht dabei vor, daß der Einlaufrollgang zusammen mit dem Hubboden und den daran gelagerten Transportrollen um einen seitlich dazu versetzten Schwenkpunkt in eine gegen die Bremsrinne zu schräg-abfallenden Neigung ausschwenkbar mit Schwenkmitteln ausgebildet ist.An embodiment essential to the invention provides that the infeed roller table together with the lifting floor and on it stored transport rollers by a laterally offset Pivot point in against the brake trough sloping incline can be swung out using swiveling means is trained.
Nach einer weiteren Ausgestaltung sind dabei die Bremsrinne und der Einlaufrollgang derart einander zugeordnet, daß in angehobener Lage des aufschwenkbaren Einlaufrollganges dessen von den Transportrollen gebildete Transportebene den Boden der Bremsrinne im parallelen Abstand überragt, wobei der Boden und der Hubboden eine gemeinsame schiefe Ebene bilden. Andere vorteilhafte Ausgestaltungen der erfindungsgemäßen Vorrichtung sind entsprechend den Unteransprüchen vorgesehen.According to a further embodiment, the brake trough and the infeed roller table are assigned to one another such that in raised position of the swiveling infeed roller table transport level formed by the transport rollers the bottom of the Brake trough protrudes at a parallel distance, the bottom and the lifting floor form a common inclined plane. Other advantageous embodiments of the device according to the invention are provided according to the subclaims.
