Abstract
Description
Die Erfindung betrifft eine Stranggießeinrichtung zum Gießen von Stahlbändern, die aus einer aus zwei gegenüberliegenden Breitseitenwänden und zwei zwischen diesen angeordneten Schmalseitenwänden gebildeten Kokille, mindestens einem nachfolgenden Rollen- oder Walzenpaar und einer Bereiche zum Abdichten der Kokille, zur Bildung einer Angießverbindung sowie zum Stützen und Ausfördern des gegossenen Stahlbandes aufweisenden Anfahrvorrichtung besteht.The invention relates to a continuous casting device for casting steel strips, which consists of a mold formed from two opposite broad side walls and two narrow side walls arranged between them, at least one subsequent pair of rollers or rollers and an area for sealing the mold, for forming a sprue connection and for supporting and conveying out of the cast starting device having cast steel strip.
Bekannte Anfahrvorrichtungen dieser Gattung bestehen aus einem die Kokille verschließenden und mit einer oberen Angießkontur versehen Anfahrkopf und einem mit diesem lösbar verbundenen starren oder flexiblen Strang zum Stützen und Ausfördern des gegossenen Stranges.Known starting devices of this type consist of a starting head which closes the mold and is provided with an upper casting contour and a rigid or flexible strand which is detachably connected thereto for supporting and conveying out the cast strand.
Diese kostspieligen Anfahrvorrichtungen erfordern zur Handhabung besondere Einrichtungen zur Aufbewahrung, zum Transport und zum Abtrennen vom Gießstrang, die Wartungsaufwand erfordern und bei denen Störungen auftreten können. Ein zusätzlicher Nachteil der bekannten Anfahrvorrichtungen ist es, daß die Vorbereitung eines Gusses erhebliche Zeit erfordert.These expensive start-up devices require special facilities for storage, transport and separation from the casting strand for handling, which require maintenance and in which faults can occur. An additional disadvantage of the known starting devices is that the preparation of a casting requires considerable time.
Durch die FR-A-2 610 227 ist eine aus zwei mit Drehantrieb versehenen Zylindern bestehende Stranggießeinrichtung mit nachgeordneten seitlichen, geraden Führungsbahnen und einem Treibrollenpaar bekannt. Die Stranggießeinrichtung weist zum Abstützen und Ausfördern des Gießstranges eine Platte auf, die länger ist als der Abstand der Achsebenen des Gießrollenpaares und des Treibrollenpaares mit den zwischengeordneten Führungbahnen. An der in der Breite verringerten Plattenoberseite ist ein Verankerungskopf größerer Breite und Dicke angestückt, der mit den Zylinderoberflächen eine Abdichtebene bildet. Diese Anfahrvorrichtung ist aufwendig und für eine aus Breitseitenwänden und Schmalseitenwänden gebildete Kokille nicht ausreichend betriebssicher.FR-A-2 610 227 discloses a continuous casting device consisting of two cylinders provided with a rotary drive with downstream, straight guide tracks and a pair of drive rollers. The continuous casting device has a plate for supporting and conveying out the casting strand, which is longer than the distance between the axial planes of the casting roller pair and the driving roller pair with the intermediate guide tracks. On the reduced top of the plate an anchor head of greater width and thickness is attached, which forms a sealing plane with the cylinder surfaces. This starting device is complex and not sufficiently reliable for a mold formed from broad side walls and narrow side walls.
Aufgabe der Erfindung ist die Schaffung einer betriebssicheren Anfahrvorrichtung für eine gattungsgemäße Stahlbandgießkokille, insbesondere für Stahlbänder unter 60 mm Dicke, die kostengünstig herstellbar ist, und bei der aufwendige Einrichtungen zum Transport, zur Zwischenlagerung und zum Abtrennen des Gießstranges entfallen können und deren Handhabung einfach und zeitsparend ist.The object of the invention is to provide a reliable starting device for a generic steel strip casting mold, in particular for steel strips with a thickness of less than 60 mm, which can be produced inexpensively and in which complex facilities for transport, intermediate storage and separation of the casting strand can be dispensed with and their handling is simple and time-saving is.
Diese Aufgabe wird erfindungsgemäß durch eine Anfahrvorrichtung gelöst, bei der eine Angießkontur, der Abdichtbereich und der Stütz- und Ausförderbereich durch eine einstückige Stahlplatte gebildet wird, die länger ist als der Abstand a zwischen Kokillenabdichtebene E₁ und gemeinsamer Achsebene E₂ des ersten Rollen- oder Walzenpaares.This object is achieved by a starting device in which a sprue contour, the sealing area and the support and discharge area is formed by a one-piece steel plate which is longer than the distance a between the mold sealing plane E 1 and the common
Dadurch wird eine einfache Anfahrvorrichtung geschaffen, die leicht zu handhaben und in Angießposition bringbar ist. Die neue Anfahrvorrichtung kann durch übliche Gießstrangquerteileinrichtungen vom Gießstrang getrennt werden, so daß spezielle Trennvorrichtungen entfallen können. Wegen der einfachen und kostengünstigen Herstellbarkeit ist die neue Anfahrvorrichtung bereits bei einmaliger Benutzung wirtschaftlich, zumal in diesem Fall die Vorbereitung und besondere Zwischenlager entfallen.This creates a simple starting device that is easy to handle and can be brought into the pouring position. The new starting device can be separated from the casting strand by conventional casting strand cross-section devices, so that special separating devices can be dispensed with. Because of the simple and inexpensive producibility, the new starting device is economical even with a single use, especially since in this case the preparation and special intermediate storage are omitted.
Gemäß einem weiteren Merkmal der Erfindung ist die Dicke des Abdichtbereichs 2 bis 4 mm kleiner als das entsprechende Austrittsmaß der Kokille. Auf diese Weise können an den Breitseitenwänden besondere Abdichtungen entfallen, da wegen der schnellen Erstarrung im Spalt keine Schmelze nach unten durchlaufen kann.According to a further feature of the invention, the thickness of the sealing area is 2 to 4 mm smaller than the corresponding exit dimension of the mold. In this way, special seals can be omitted on the broad side walls, since, because of the rapid solidification in the gap, no melt can pass downwards.
Eine Gewichtsersparnis und damit leichtere Handhabung der Anfahrvorrichtung wird vorteilhaft dadurch erreicht, daß der Stütz- und Ausförderbereich aus im Abstand voneinander angeordneten Streifen besteht.A weight saving and thus easier handling of the starting device is advantageously achieved in that the support and discharge area consists of strips arranged at a distance from one another.
Eine Mehrfachnutzung der Anfahrvorrichtung wird in weiterer Ausbildung der Erfindung dadurch erreicht, daß sich an beiden Enden eine Angießkontur befindet.A multiple use of the starting device is achieved in a further embodiment of the invention in that there is a sprue contour at both ends.
Eine Mehrfachnutzung kann aber auch dadurch erreicht werden, daß, die Stahlplatte eine sich aus dem Abstand a und dem Produkt aus Angießkonturhöhe h und Anzahl der Mehrfachnutzungen n nach der Formel L = a + n · h ergebende Mindestlänge hat. Die Anformung einer neuen Angießkontur geschieht vorteilhaft durch Brennschneiden.Multiple use can also be achieved by that the steel plate has a minimum length resulting from the distance a and the product of the casting contour height h and the number of multiple uses n according to the formula L = a + n · h. A new cast-on contour is advantageously formed by flame cutting.
Die Angießkontur kann durch Verbindungsköpfe an der Stirnseite des Abdichtbereichs gebildet werden. Alternativ können in der Stirnseite des Abdichtbereichs mehrere mit Hinterschneidungen versehene Öffnungen angeordnet sein. Dabei kann eine freie Schrumpfung des gegossenen Stahlbandes zur Vermeidung von Schrumpfrissen dadurch ermöglicht werden, daß die äußeren Öffnungen nur an der Außenseite eine Hinterschneidung aufweisen.The cast-on contour can be formed by connecting heads on the end face of the sealing area. Alternatively, a plurality of openings provided with undercuts can be arranged in the end face of the sealing area. A free shrinkage of the cast steel strip to avoid shrinkage cracks can be made possible by the fact that the outer openings have an undercut only on the outside.
In der Stirnseite des Abdichtbereichs können Gewindelöcher für mit Gewinde versehene Tragstangen eines Hebezeugs angeordnet sein.Threaded holes for threaded support rods of a hoist can be arranged in the end face of the sealing area.
