Die Erfindung bezieht sich auf eine Richtmaschine zum Geraderichten von aus einer vertikalen Stranggießanlage für Metalle und deren Legierungen austretenden, in einer Umführungsvorrichtung in die Horizontale umgelenkten Gießstränge. Bei derartigen Stranggießanlagen kann die Krümmung des oder der Stränge zur Umlenkung in die Horizontale durch eine gekrümmt ausgebildete Kokille oder aber bei Verwendung einer Kokille mit ebenen Innenflächen durch eine besondere Abbiegevorrichtung unterhalb der Kokille herbeigeführt werden. Der Transport des Gießstranges und damit auch die Bestimmung der Gießgeschwindigkeit geschieht mittels einer unterhalb der Gießkokille angeordneten, am Gießstrang angreifenden Walzenzugmaschine.The invention relates to a straightening machine for straightening from a vertical continuous caster for metals and their alloys escaping, in a bypass device in the Horizontal deflected cast strands. In such continuous casting plants, the curvature of the or Strands for deflecting into the horizontal through a curved mold or else at Use of a mold with flat inner surfaces through a special bending device underneath the mold are brought about. The transport of the cast strand and thus also the determination of the The casting speed takes place by means of an arranged below the casting mold, on the cast strand attacking compactor.
In beiden Fällen ist es erforderlich, den gekrümmten Strang in der horizontalen Richtung wieder geradezubiegen. Zum Geradebiegen und Richten des in die Horizontale umgelenkten Stranges dienen Richtmaschinen. Bei einer bekannten derartigen Richtmaschine sind in Niveauhöhe des Richtwalzentisches eine größere Anzahl von Richtwalzen gelagert, auf denen der gegossene Strang in horizontaler Richtung bewegt und auf die er mittels an Hebelarmen oder Lenkern gelagerten gewichtsbelasteten Druckwalzen angedrückt wird.In both cases it is necessary to re-align the curved strand in the horizontal direction straighten it. Serve for straightening and straightening the strand deflected horizontally Straightening machines. In a known such straightening machine are at the level of the straightening roller table stored a larger number of straightening rollers on which the cast strand in horizontal Moved direction and on which he is weight-loaded by means of lever arms or handlebars mounted Pressure rollers is pressed.
Ausgehend von dem Bestreben, die Bauhöhe einer derartigen Stranggießanlage so klein wie möglich zu halten, besteht die Aufgabe der Erfindung darin, solche Maßnahmen zu treffen, die es ermöglichen, auf eine Walzenzugmaschine unterhalb des mit der Kokille versehenen Gießtisches zu verzichten.Based on the endeavor to keep the overall height of such a continuous caster as small as possible hold, the object of the invention is to take measures that make it possible to forego a roller pulling machine below the casting table provided with the mold.
Nach dem Grundgedanken der Erfindung soll die Richtmaschine die Funktion des Strangzuges mitübernehmen, daß eine besondere Walzenzugmaschine entbehrlich ist.According to the basic idea of the invention, the straightening machine should also take over the function of the strand pull, that a special compactor is dispensable.
Dies geschieht nach der Erfindung dadurch, daß die Richtmaschine mit mindestens einem Paar angetriebener Transportwalzen versehen ist, von denen die Oberwalze mittels eines Kraftgerätes unmittelbar auf den Strang andrückbar ist und wobei an der Walzenachse der Oberwalze mittels eines Lenkerpaares eine zweite, ebenfalls mittels Kraftantrieb unmittelbar auf den Strang andrückbare, mit einer Unterwalze zusammenwirkende Geradebiegeoberwalze angelenkt ist.This is done according to the invention in that the straightening machine is driven with at least one pair of Transport rollers are provided, of which the top roller is directly by means of a power device can be pressed onto the strand and wherein on the roller axis of the upper roller by means of a pair of links a second, which can also be pressed directly onto the strand by means of a power drive, with a Lower roller cooperating straightening upper roller is articulated.
Durch den erfindungsgemäßen Vorschlag wird eine besonders einfache und wirksame Geradebiege- und Richtvorrichtung für gekrümmte Gießstränge geschaffen, bei der infolge des Zusammenwirkens der angetriebenen Transport- mit der Biegewalze ein stets gleichmäßiger Durchzug und ein wirksamesThe proposal according to the invention is a particularly simple and effective straight bending and created straightening device for curved cast strands, in which as a result of the cooperation the driven transport with the bending roller an always even passage and an effective

Richten des Stranges ermöglicht wird. Insbesondere werden Stauchungen des noch nicht völlig erstarrten
Stranges durch eine unterhalb der Kokille angeordnete Walzenzugmaschine vermieden.
Besonders vorteilhaft ist es nach einem zusätzliehen Merkmal der Erfindung, wenn die am Lenkerpaar
gelagerte Geradebiegewalze angetrieben ist. Der Antrieb der Geradebiegeoberwalze, die den
gesamten Biegedruck aufzunehmen hat, ist daher infolge der hohen Haftreibung besonders geeignet,
einen gleichmäßigen Durchzug des Stranges zu bewirken. Straightening the strand is made possible. In particular, compression of the not yet completely solidified strand is avoided by a roller pulling machine arranged below the mold.
According to an additional feature of the invention, it is particularly advantageous if the straightening roller mounted on the pair of links is driven. The drive of the straight bending upper roller, which has to absorb the entire bending pressure, is therefore particularly suitable, due to the high static friction, to cause the strand to be pulled through evenly.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung schematisch dargestellt und im folgenden näher erläutert: Der Strang 1 läuft zwischen die Walzen der Transportvorrichtung 2, 3 ein. Die untere Transportwalze 3 ist in Niveauhöhe des Geradebiege-Walzentisches gelagert, der mit weiteren Walzen 4, 5, 6 ausgerüstet ist.An embodiment of the invention is shown schematically in the drawing and explained in more detail below: The strand 1 runs between the rollers of the transport device 2, 3. The lower transport roller 3 is mounted at the level of the straight-bending roller table, which is equipped with further rollers 4, 5, 6.
Die obere Transportwalze 2 ist auf verschiedene Strangdicken einstellbar und mittels eines Kraftgerätes 7 auf die Gegenwalze 3 anpreßbar.The upper transport roller 2 can be adjusted to different strand thicknesses and by means of a power device 7 can be pressed onto the counter roller 3.
Im Drehpunkt der oberen Transportwalze 2 ist ein Ausleger 8 angelenkt, an dem eine Geradebiegewalze 9 in einem solchen Abstand angeordnet ist, daß sie mit der Gegenwalze 6 des Walzentisches zusammenwirkt. Der Ausleger 8 ist mittels eines weiteren Kraftgerätes 10 in Richtung auf den Walzentisch andrückbar, wodurch das Geradebiegen des Stranges hervorgerufen wird.At the pivot point of the upper transport roller 2, a boom 8 is articulated on which a straightening roller 9 is arranged at such a distance that it cooperates with the counter roller 6 of the roller table. The boom 8 is by means of a further power device 10 in the direction of the roller table can be pressed, whereby the straightening of the strand is caused.
