Description
Die Erfindung betrifft ein Verfahren zur Herstellung von Brammen, insbesondere aus Stahl in unterschiedlichen Formaten in einer Breit- und Schmalseitenwände aufweisenden stationären Kokille einer Stranggießanlage, bei der zur Änderung des Formates die Anpreßkraft auf die entsprechenden Kokillenseitenwände reduziert und mindestens eine der Kokillenwände bei angemessener Anpreßkraft in die gewünschte Position verfahren wird sowie eine entsprechende Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for producing slabs, in particular from Steel in different formats in a wide and narrow side walls stationary mold of a continuous caster, when changing the format the contact pressure on the corresponding mold side walls is reduced and at least one of the mold walls with the appropriate contact pressure in the desired position is moved and a corresponding device for performing the method.
Aus der DE-OS 27 02 976 ist eine Plattenkokille zum Stranggießen von Stahl bekannt, bei der die Schmalseiten mittels einer Klemmeinrichtung zwischen den Breitseitenwänden festklemmbar ist. Im Verstellbereich der Schmalseitenwände dieser Vorrichtung sind die Breitseitenwände parallel zueinander angeordnet. Eine Veränderung der Distanz der Breitseitenwände und damit eine Formatänderung der Bramme mit den installierten Seitenwänden ist hiermit nicht möglich.A plate mold for the continuous casting of steel is known from DE-OS 27 02 976, in which the narrow sides by means of a clamping device between the broad side walls can be clamped. In the adjustment area of the narrow side walls of this device the broad side walls are arranged parallel to one another. A change in Distance of the broad side walls and thus a change in format of the slab with the installed side walls is not possible with this.
Weiterhin ist aus der EP 0 658 387 A1 eine Kokille zum Stranggießen von Stahlband bekannt, deren Breitseitenwände seitlich eines trichterförmigen Eingießbereiches mit sich nach außen zu den Schmalseiten einander annähernden Schrägflächen ausgebildet sind.Furthermore, from EP 0 658 387 A1 there is a mold for the continuous casting of steel strip known, the wide side walls with a funnel-shaped pouring area outward inclined surfaces are formed towards the narrow sides are.
Während im erstgenannten Fall beim Bewegen der Schmalseitenwände die Breitseitenwände ihre Distanz zueinander beibehalten, so daß die Distanz der Rollen im nachfolgenden Strangführungsgerüst nicht verstellt zu werden braucht, bewegen sich im letztgenannten Beispiel bei einer Verstellung der Schmalseitenwände die Breitseitenwände relativ zueinander.While in the former case, when moving the narrow side walls, the wide side walls maintain their distance from each other, so that the distance of the roles in subsequent strand guide scaffold does not need to be moved, move in the latter example, when the narrow side walls are adjusted, the wide side walls relative to each other.
Nachteilig ist bei den bekannten Lösungen, daß im ersten Fall die Brammendicke nicht vergrößert bzw. verkleinert und im zweiten Fall, daß die Verstellung der Brammendicke nur bei gleichzeitiger Veränderung der Brammenbreite durchgeführt werden kann, d.h., daß bei einer Dickenverstellung zwangszweise schmalere bzw. breitere Brammen entstehen.A disadvantage of the known solutions is that the slab thickness is not in the first case enlarged or reduced and in the second case that the adjustment of the slab thickness can only be carried out if the slab width is changed at the same time, i.e. that with a thickness adjustment inevitably narrower or wider slabs arise.
Bei Kenntnis der geschilderten Nachteile hat sich die Erfindung zum Ziel gesetzt, ein Verfahren und eine entsprechende Vorrichtung zur Herstellung von Brammen nicht nur in beliebigen Breiten, sondern auch in beliebigen Dicken zu ermöglichen.With knowledge of the disadvantages described, the invention has set itself the goal of Process and a corresponding device for the production of slabs not only in any width, but also in any thickness.
Die Erfindung erreicht dieses Ziel durch die Merkmale des Verfahrensanspruches 1 und des Vorrichtungsanspruches 3.The invention achieves this goal by the features of the method claim 1 and the device claim 3.
Erfindungsgemäß werden zur Änderung des Formates der Bramme die Abstände der Schmalseitenwände und damit die Breite der Bramme und/oder die Abstände der Breitseitenwände und somit die Dicke der Bramme beliebig vorgebbar verändert. In einer vorteilhaften Ausgestaltung wird das Format so eingestellt, daß zwischen zwei Formatänderungen die Belastung der Strangschale dadurch optimiert wird, daß der Umfang in der jeweiligen Höhe der Kokille in etwa konstant gehalten wird.According to the invention, the distances of the slab to change the format Narrow side walls and thus the width of the slab and / or the spacing of the Broad side walls and thus the thickness of the slab can be changed as desired. In an advantageous embodiment, the format is set so that between two Format changes, the load on the strand shell is optimized in that the Scope in the respective height of the mold is kept approximately constant.
Die zur Durchführung des Verfahrens erforderliche Stranggießkokille ist aus jeweils zwei Breitseiten- und zwei Schmalseitenwänden zusammengesetzt, wobei die Schmalseitenwände aus keilförmigen Teilen zusammengefügt werden. Die Schmalseitenwände bestehen dabei aus mindestens zwei keilförmigen Leisten, deren äußere Berührungsflächen sich an die Innenwand der Breitseiten lehnen und deren einander zugewandte Berührungsflächen über die gesamte Länge der einzelnen Teile geführt ist.The continuous casting mold required to carry out the process is in each case put together two broad sides and two narrow side walls, the Narrow side walls can be assembled from wedge-shaped parts. The narrow side walls consist of at least two wedge-shaped strips, the outer Contact surfaces lean against the inner wall of the broad sides and their each other facing contact surfaces over the entire length of the individual parts is.
Die einander zugewandten Berührungsflächen sind dabei in einer Ebene geführt, die im wesentlichen die gleiche Richtung wie die entsprechenden Breitseitenflächen aufweisen und unter einem Drehwinkel von γ zwischen 0 und 30° einander zugewandt sind. Die von 0° abweichende Winkeleinstellung unterstützt die Anpressung der Schmalseiten- zu den Breitseitenwänden.The mutually facing contact surfaces are guided in one plane, the have substantially the same direction as the corresponding broad side surfaces and facing each other at an angle of rotation of γ between 0 and 30 ° are. The angle setting deviating from 0 ° supports the pressing of the Narrow sides to the broad side walls.
In einer vorteilhaften Ausgestaltung sind an dieser Stelle eine Nut und eine Feder vorgesehen. Der Keilwinkel α der Seitenflächenteile ist vorzugsweise zwischen 3 und 6° gewählt. Dieser Winkelbereich erweist sich als ausreichend, um bei angemessener vertikaler Verstellung eines Teils der Schmalseiten sicher die gewünschte Dicke der Bramme einzustellen.In an advantageous embodiment, a groove and a tongue are provided at this point. The wedge angle α of the side surface parts is preferably between 3 and 6 ° selected. This angular range proves sufficient to be more appropriate vertical adjustment of part of the narrow sides ensures the desired thickness of the slab adjust.
Die erfindungsgemäßen für verschiedene Brammendicken einstellbaren Schmalseiten sind nicht nur bei Breitseiten einsetzbar, die im Schmalseitenverstellbereich parallelwandig angeordnet sind, sondern auch bei einander keilförmig zugeordneten Breitseiten im Schmalseitenverstellbereich. In einer vorteilhaften Ausgestaltung wird hier ein Konuswinkel β von 0,2 ° bis 2,5 ° vorgesehen.The narrow sides according to the invention which are adjustable for different slab thicknesses are not only usable on broad sides that are parallel-walled in the narrow side adjustment area are arranged, but also with wedge-shaped associated broad sides in Schmalseitenverstellbereich. In an advantageous embodiment, a cone angle β is used here from 0.2 ° to 2.5 °.
Die erfindungsgemäßen verstellbaren Schmalseiten sind aber nicht nur für vertikale stationäre Kokillen, sondern auch für Kokillen einer Bogenstranggießanlage verwendbar. Bei dieser Ausgestaltung folgen die keilförmigen Teile an ihren einander zugewandten Flächen einem konstanten Radius, dessen Mittelpunkt verschieden ist von denen der einzelnen Breitseitenradien. Bei der paarweisen Verstellbewegung mindestens eins der jeweiligen Schmalseitenteile werden diese auf einem Kreisbogen bewegt, der dem Radius der verstellten Breitseite folgt.However, the adjustable narrow sides according to the invention are not only for vertical ones stationary molds, but can also be used for molds in a continuous caster. at this configuration is followed by the wedge-shaped parts on their mutually facing surfaces a constant radius, the center of which is different from that of the individual Broadside radii. With the pairwise adjustment movement at least one of the respective Narrow side parts are moved on an arc that corresponds to the radius of the adjusted broadside follows.
In einer weiteren vorteilhaften Ausgestaltung werden je Schmalseite drei Teile eingesetzt, wobei der mittlere Keil symmetrisch ausgestaltet ist. Hierbei können die Berührungsflächen der einzelnen Seitenteile parallel zu den Breitseitenflächen oder auch konisch zu diesen angeordnet sein. Bei dem Einsatz eines Mittenteils mit doppelkonischer Ausgestaltung wird eine besonders innige Verklemmung der Seitenteile erreicht. Andererseits wird dadurch erreicht, daß bei einer Verstellung der Schmalseiten die Breitseiten im Verstellbereich gar keinen oder nur horizontalen Bewegungen ausgesetzt sind.In a further advantageous embodiment, three parts are used on each narrow side, the middle wedge is symmetrical. Here, the contact surfaces of the individual side parts parallel to the broad side surfaces or also conical to these be arranged. When using a middle part with a double-conical design achieved a particularly intimate jamming of the side parts. On the other hand, it will achieved that the wide sides in the adjustment range even at an adjustment of the narrow sides are exposed to no or only horizontal movements.
Um eine horizontale Bewegung der Schmalseiten auch ohne Veränderung ihrer Dicke zu erreichen wird vorgeschlagen, zwischen der Verstelleinrichtung und dem bewegbaren keilförmigen Teil eine Kupplung anzuordnen.To allow horizontal movement of the narrow sides even without changing their thickness It is proposed to reach between the adjusting device and the movable one wedge-shaped part to arrange a clutch.

each narrow side (31, 32) consists of at least two wedge-shaped components (33, 34), the contact surfaces (41, 42) facing one another extend over the full length, i.e. the height of the narrow side wall in the case of each component (33, 34) and the plane (E) between the surfaces (41, 42) in contact extends essentially in the same direction as the corresponding inside surfaces (51, 52) of the wide sides with a rotation angle of γ = 0 to 30° to one another, and
in each case at least one wedge-shaped component (33, 34, 35) is connected to a displacement mechanism (37, 38) acting in the strand movement direction (S). - Continuous casting mould according to Claim 3,
characterised in that
the wedge angle α of the surfaces of the sidepieces (33-35) is in the range α = 3° to 6°. - Continuous casting mould according to Claim 3,
characterised in that
the narrow sides (31, 32) are formed with conical divergence in the direction of the slab mould cavity (11), such that the narrow sides (31, 32) have outer contact surfaces (45) that correspond with the inside surfaces (51, 52) of the wide sides (21, 22) in the adjustment zone (23). - Continuous casting mould according to Claim 5,
characterised in that
the cone angle β of the wide sides (21, 22) in the adjustment zone (23) of the narrow sides is of the order of β = 0.2° to 2.5°. - Continuous casting mould according to Claim 3,
characterised in that
in a metal mould for a curved continuous casting unit the wedge-shaped components (73, 74) have corresponding radii (Rm) of their adjacent contact surfaces, while the outer contact surfaces (85, 86) of the wedge-shaped components (71, 72) are shaped to fit the converging inside surfaces (91, 92) of the wide sides (61, 62) of the mould in the adjustment zone. - Continuous casting mould according to any of the preceding claims,
characterised in that
the inside contact surface (41, 81) of one wedge-shaped component (31, 71) has a groove (78) and the corresponding inside surface (42, 82) of the other wedge-shaped component (34, 72) has a corresponding spring (79). - Continuous casting mould according to any of the preceding claims,
characterised in that
each narrow side (31, 32) consists of a total of three wedge-shaped components (33-35). - Continuous casting mould according to Claim 3,
characterised in that
the components (33, 34, 71, 72) are connected to the displacement mechanism (37 or 38) in such manner that they can be moved horizontally without hindrance. - Continuous casting mould according to Claim 9,
characterised in that
a coupling (39) is provided between the displacement mechanism (37, 38) and the movable wedge-shaped component (33, 72).
