Description

Die Erfindung betrifft einen Vorschubmechanismus für den gegossenen Strang in einer Anlage zum kontinuierlichenThe invention relates to a feed mechanism for the cast strand in a plant for continuous

Strangguß von Stahl.Continuous casting of steel.

An den Stahlstranggußanlagen wurden bisher zwei Mechanismen verwendet. Der eine dient zur Erzeugung einer Hin- und Herbewegung des Kristallisators um dem Anhaften des Strangs an die Kristallisatorwinde vorzubeugen, der zweite Mechanismus dagegen, der mit Zugwalzen versehen ist, dient zum Bewegen des Gußstrangs mit bestimmter Geschwindigkeit.Two mechanisms have so far been used on the continuous steel casting plants. One is used to generate a back and forth movement of the crystallizer in order to prevent the strand from sticking to the crystallizer winch, while the second mechanism, which is provided with pulling rollers, is used to move the cast strand at a certain speed.

Beide Werke sind mit elektrischen synchronen Antrieben versehen. Jeder Mechanismus hat einen Motor, eine Kupplung, Zahnradgetriebe und einen Walzsatz mit kompliziertem Gehäuse, wobei die Walzen mit Wasser gekühlt sind.Both plants are equipped with electrical synchronous drives. Each mechanism has a motor, a clutch, gears and a set of rollers with a complicated housing, the rollers being water-cooled.

Diese Anlagen weisen einen komplizierten Bau auf, der mit beträchtlichen Investitionskosten verbunden ist und eine sehr sorgfältige Bedienung während des Betriebes erfordert. Auch die unentbehrliche Genauigkeit des Prozesses wirkt auf die Steigerung der Kosten ein.These systems have a complicated construction, which is associated with considerable investment costs and requires very careful operation during operation. The indispensable accuracy of the process also has an effect on the increase in costs.

Ausserdem verlangen die bekannten Mechanismen bei Änderung des Profils beim kontinuierlichen Stranggiessen einen Austausch nicht nur des Kristallisators doch auch der Walzen, was ungelegen und zeitraubend ist.In addition, when the profile changes during continuous casting, the known mechanisms require an exchange not only of the crystallizer but also of the rollers, which is inconvenient and time-consuming.

Der erfindungsgemäße Mechanismus weist diese Nachteile nicht auf. Er zeichnet sich durch einfachen Bau auf, ist billig und bündig, und übt beide Tätigkeiten zugleich aus, ohne grösseren Arbeitsaufwand. Ausserdem ist bei einer Profiländerung nur der Austausch der Klemmbecken erforderlich. Er ist dadurch gekennzeichnet, daß er zwei greifende, symmetrisch zu dem kontinuierlichen Gußstrang anzulegende Klemmbacken besitzt, die gelenkig auf Hebeln aufgelagert sind, daß der Drehpunkt der Hebel mit einem Rahmen verbunden ist, und daß das andere Ende des Hebels hin- und hergehend durch ein, insbesondere hydraulisches, Triebwerk über eine Schwinge angetrieben wird, wobei die Schwinge und der Rahmen frei auf Führungen verschiebbar sind.The mechanism according to the invention does not have these disadvantages. It is characterized by simple construction, is cheap and flush, and carries out both activities at the same time, without a great deal of work. In addition, if the profile is changed, only the terminal basin has to be exchanged. It is characterized in that it has two gripping jaws to be applied symmetrically to the continuous cast strand, which are articulated on levers, that the pivot point of the lever is connected to a frame, and that the other end of the lever reciprocates through a , in particular hydraulic, engine is driven via a rocker arm, the rocker arm and the frame being freely displaceable on guides.

Der erfindungsgemäße Mechanismus soll nachstehend an einem Ausführungsbeispiel näher erläutert werden. In der zugehörigen Zeichnung zeigen zum Teil im SchnittThe mechanism according to the invention will be explained in more detail below using an exemplary embodiment. In the accompanying drawing show partly in section

Fig. 1 die Seitenansicht undFig. 1 the side view and

Fig. 2 die Draufsicht.Fig. 2 is a top view.

Zwei, den Gußstrang 1 greifende Klemmbacken 1 sind gelenkig auf den Hebeln 3 angebracht, deren Drehpunkt mit dem Rahmen 4 verbunden ist.Two clamping jaws 1 gripping the cast strand 1 are articulated on the levers 3, the pivot point of which is connected to the frame 4.

Die anderen Enden der Hebel 3 erhalten einen hin- und hergehenden Antrieb von den hydraulischen Triebwerken 5 über die Schwinge 6. Die Schwinge 6 und der Rahmen 4 verschieben sich frei auf Führungen 7.The other ends of the levers 3 receive a reciprocating drive from the hydraulic drives 5 via the rocker 6. The rocker 6 and the frame 4 slide freely on guides 7.

Die Führungen 7 sind in einem Vordergestell 8 und einem Hintergestell 9 befestigt. An dem Vordergestell 8 sind die hydraulischen Triebwerke 5 befestigt. Die Schwinge 6 ist mit Mitnehmern 10 versehen. Der Rahmen 4, die Schwinge 6, das Vordergestell 8 und das Hintergestell 9 sind von innen mit Umlaufwasser gekühlt. Die Klemmbacken 1 sind auswechselbar wegen der wechselnden Querschnittsform des Gußstrangs.The guides 7 are fastened in a front frame 8 and a rear frame 9. The hydraulic engines 5 are attached to the front frame 8. The rocker 6 is provided with drivers 10. The frame 4, the rocker 6, the front frame 8 and the rear frame 9 are cooled from the inside with circulating water. The clamping jaws 1 are exchangeable because of the changing cross-sectional shape of the cast strand.

Der Vorschubmechanismus arbeitet wie folgt:The feed mechanism works as follows:

Während der Tätigkeit der hydraulischen Triebwerke, verschiebt sich die Schwinge 6 auf den Führungen 7 nach vorn und drückt das Ende des Hebels 3, wobei die Klemmbacken 1 auf den Gußstrang 2 geklemmt werden. Der weitere Druck der Schwinge 6 auf die Hebel 13 bewirkt eine Verschiebung der Hebel mit dem Rahmen 4 auf den Führungen 7 und eine Verschiebung des mit den Klemmbacken 1 ergriffenen Gußstrangs 2 nach vorn.During the operation of the hydraulic drives, the rocker 6 moves forward on the guides 7 and presses the end of the lever 3, the clamping jaws 1 being clamped onto the cast strand 2. The further pressure of the rocker 6 on the lever 13 causes a displacement of the lever with the frame 4 on the guides 7 and a displacement of the cast strand 2 gripped with the clamping jaws 1 forwards.

Während der Zurückbewegung verschieben die hydraulischenDuring the return movement, the hydraulic ones move

Triebwerke 5 die Schwinge 6 nach hinten. Mittels der Mitnehmer 10 öffnet die Schwinge 6 die Hebel 3, wodurch die Klemmbacken 1 entklemmt werden; weiter wird der Rahmen 4 nach hinten verschoben.Engines 5 the swing arm 6 to the rear. By means of the driver 10, the rocker 6 opens the lever 3, whereby the clamping jaws 1 are disengaged; further the frame 4 is shifted to the rear.
