Description

Die Erfindung betrifft eine Vorrichtung zum Führen von Stranggussprofilen oder Brammen.The invention relates to a device for guiding continuous casting profiles or slabs.

Derartige Vorrichtungen zum Führen von Stranggussprofilen oder Brammen sind im Stand der Technik grundsätzlich bekannt. Sie umfassen typischerweise eine Kühlwassereinrichtung zum Bereitstellen von Kühlwasser zum Kühlen der Stranggussprofile oder Brammen und mindestens eine Strangführungsrolle zum Führen der Brammen oder Stranggussprofile durch die Vorrichtung. Aus der japanischen Patentanmeldung JP 61033746 A ist es bekannt, dass derartige Strangführungsrollen auf Ihrer Oberfläche eine gewendelte Nut ausgebildet haben können. Weiterhin ist es aus der japanischen Patentanmeldung JP 8047757 bekannt, dass derartige Strangführungsrollen mehrere benachbarte Teilrollen aufweisen können, wobei die Oberflächen der Teilrollen jeweils wiederum mit einer Nut versehen sein können. Wenn eine Strangführungsrolle mehrere Teilrollen aufweist, gibt es zwangsläufig eine linke äußere Teilrolle, welche dem linken Randbereich des Strangprofils oder der Brammen zugeordnet ist, sowie eine rechte äußere, dem rechten Randbereich der Brammen zugeordnete Teilrolle.Such devices for guiding continuous casting profiles or slabs are basically known in the prior art. They typically include cooling water means for providing cooling water for cooling the continuous casting profiles or slabs and at least one strand guiding roll for guiding the slabs or continuous casting profiles through the apparatus. From the Japanese patent application JP 61033746 A It is known that such strand guide rollers may have formed a coiled groove on its surface. Furthermore, it is from the Japanese patent application JP 8047757 It is known that such strand guide rollers may have a plurality of adjacent sub-rollers, wherein the surfaces of the sub-rollers may in each case in turn be provided with a groove. If a strand-guiding roller has a plurality of sub-rollers, there is inevitably a left outer sub-roller, which is assigned to the left-hand edge region of the extruded profile or of the slabs, and a right-outer sub-roller assigned to the right-hand edge region of the slabs.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, Strangführungsrollen einer Vorrichtung zum Führen von Stranggussprofilen oder Brammen dahingehend weiterzubilden, dass auf der Brammenoberfläche vorhandenes Kühl- bzw. Schwallwasser wahlweise entweder möglichst lange auf der Brammenoberfläche verbleibt oder möglichst schnell von der Brammenoberfläche abgeführt wird.Based on this prior art, the present invention seeks to develop strand guide rollers of a device for guiding continuous casting profiles or slabs in that on the slab surface existing cooling or splash water either either as long as possible on the slab surface or removed as quickly as possible from the slab surface becomes.

Diese Aufgabe wird durch den Gegenstand des Patentanspruchs 1 gelöst. Demnach wird eine bekannte Vorrichtung zum Führen von Stranggussprofilen oder Brammen, wie sie einleitend beschrieben wurde, dahingehend weitergebildet, dass eine Kühlwassereinrichtung zum Bereitstellen von Kühlwasser zum Kühlen der Brammen vorgesehen ist, die Nut auf der linken äußeren Teilrolle und die Nut auf der rechten äußeren Teilrolle jeweils in Form eines Gewindes ausgebildet ist und das Vorzeichen der Steigung der gewindeförmigen Nut auf der linken äußeren Teilrolle entgegengesetzt zu dem Vorzeichen der Steigung der gewindeförmigen Nut auf der rechten äußeren Teilrolle gewählt ist.This object is solved by the subject matter of patent claim 1. Accordingly, a known apparatus for guiding continuous casting profiles or slabs, as described in the introduction, is further developed in that a cooling water means is provided for providing cooling water for cooling the slabs, the groove on the left outer sub-roll and the groove on the right outer sub-roll is formed in the form of a thread and the sign of the pitch of the thread-shaped groove on the left outer part of the role opposite to the sign of the pitch of the thread-shaped groove on the right outer part of the roller is selected.

Das Vorsehen der Nuten in den Oberflächen der Teilrollen hat insbesondere bei einer vertikalen Führung der Brammen durch die Vorrichtung den Vorteil, dass das Kühlwasser nicht nur im Bereich eines Mittellagers zwischen den beiden äußeren Teilrollen, sondern zusätzlich auch durch die Nuten abfließen kann. Dies hat den Vorteil, dass der durch den Abstand des Lagers zur Oberfläche der Brammen gebildete Wasser-Ablaufkanal entlastet und weniger Kühlwasser dort hindurch abfließt. Die Gewindeförmige Ausbildung der Nut bewirkt vorteilhafterweise, dass sich auf der Brammenoberfläche keine Wasserablaufkanäle bilden, weil der Kontaktbereich zwischen Nut und Brammenoberfläche bei einer Drehung der Teilrollen quer zur Brammenlaufrichtung wandert. Die Wanderung dieses Kontaktbereiches quer zur Brammenlaufrichtung hat weiterhin zur Folge, dass das Wasser nicht nur über die Nuten abgeführt, sondern von diesen auch zumindest teilweise in die jeweilige Bewegungsrichtung des Kontaktbereiches zwischen Nut und Brammenoberfläche transportiert wird. Je nach Drehrichtung der Strangführungsrollen bzw. der Teilrollen und dem Vorzeichen der Steigung der Nuten auf den Teilrollen, werden die Teile des Kühlwassers, die nicht durch die Nuten oder im Bereich des Lagers abfließen, sondern als Schwallwasser auf der Brammenoberfläche verbleiben, entweder zur Brammenmitte oder an die Brammenränder transportiert.The provision of the grooves in the surfaces of the sub-rollers has the advantage that the cooling water can flow out not only in the region of a central bearing between the two outer sub-rollers, but in addition also through the grooves, in particular with a vertical guidance of the slabs. This has the advantage that the water drainage channel formed by the distance of the bearing to the surface of the slabs relieves and less cooling water flows through it. The thread-shaped design of the groove advantageously causes no water drainage channels to form on the slab surface, because the contact area between the groove and the slab surface transverses with a rotation of the partial rolls transversely to the direction of slab travel. The migration of this contact region transverse to the slab running direction further has the consequence that the water is not only removed via the grooves, but is also transported by these at least partially in the respective direction of movement of the contact region between the groove and slab surface. Depending on the direction of rotation of the strand guide rollers or sub-roles and the sign of the slope of the grooves on the sub-rollers, the parts of the cooling water, which do not flow through the grooves or in the area of the camp, but remain as splash water on the slab surface, either to the slab center or transported to the slab edges.

Die beanspruchten entgegengesetzten Vorzeichen der Steigungen der gewindeförmigen Nuten auf den äußeren Teilrollen ermöglichen vorteilhafterweise, dass das Schwallwasser von den beiden äußeren Rollen her wahlweise entweder zur Brammenmitte hin geführt, das heißt auf der Brammenoberfläche gehalten wird, um diese weiterhin zu kühlen oder sehr schnell von der Brammenoberfläche abgeführt wird, wie es zum Beispiel am Ausgang der Vorrichtung zum Führen von Stranggussprofilen sinnvoll sein kann.The claimed opposite signs of the pitches of the thread-shaped grooves on the outer part rollers advantageously allow the splash water from either outer rollers either selectively to the center of the slab out, that is held on the slab surface to continue to cool them or very quickly from the Slab surface is removed, as it may be useful, for example, at the output of the device for guiding continuous casting profiles.

Gemäß der Erfindung fasst die Strangführungsrolle der Vorrichtung neben den beiden äußeren Teilrollen zusätzlich noch eine zwischen ihnen gelagerte Zwischenrolle. Auf der Oberfläche dieser Zwischenrolle ist ebenfalls eine Nut, in Form eines Gewindes, das heißt eine gewendelte Nut vorgesehen, um eine Streifenbildung auf der Brammenoberfläche zu vermeiden, wie sie bei einem Nutverlauf mit einer Steigung von Null aufgrund des dann resultierenden lokal festpositionierten Wasserablaufkanal auf der Brammenoberfläche resultieren würde.According to the invention, the strand-guiding roller of the device, in addition to the two outer sub-rollers, additionally holds an intermediate roller mounted between them. On the surface of this intermediate role is also a groove, in the form of a thread, that is a coiled groove provided to avoid streaking on the slab surface, as in a Nutverlauf with a slope of zero due to the then locally fixed water drainage channel on the Slab surface would result.

In einem Eingangs- oder Mittelbereich der Vorrichtung zum Führen von Stranggussprofilen sind die Vorzeichen der Steigungen der gewindeförmigen Nuten auf den beiden äußeren Teilrollen so gewählt, dass die Kontaktbereiche der Nuten mit der Brammenoberfläche bei den beiden äußeren Teilrollen im Falle einer Drehung der Teilrollen in Richtung Brammenmitte mitwandem. Dann werden auch die nichtabfließenden Teile des Kühlwassers zur Brammenmitte geführt; das heißt der Großteil des Kühlwassers wird auf der Brammenoberfläche gehalten und steht dort für Kühlzwecke zur Verfügung.In an input or central region of the apparatus for guiding continuous casting profiles, the signs of the pitches of the thread-like grooves on the two outer sub-rollers are chosen so that the contact areas of the grooves with the slab surface in the two outer sub-rollers in the case of rotation of the sub-rollers in the direction of slab center mitwandem. Then, the non-flowing parts of the cooling water are fed to the slab center; that is, the majority of the cooling water is held on the slab surface and is available there for cooling purposes.

Sind bei einer Strangführungsrolle im Eingangs- oder Mittelbereich der Vorrichtung zum Führen von Stranggussprofilen mehrere Zwischenrollen vorhanden, so ist es vorteilhaft, wenn die Vorzeichen der Steigungen der gewindeförmigen Nuten auf diesen Zwischenrollen alternierend gewählt sind. Dann wird nicht eine Bewegung des Kühlwassers in eine bevorzugte Richtung quer zur Brammenoberfläche verstärkt, wie dies der Fall wäre, wenn die Vorzeichen auf den Zwischenrollen alle gleich ausgebildet wären; stattdessen wird durch das Alternieren der Vorzeichen bei den Nuten der Zwischenrolle vorteilhafterweise eine gleichmäßigere Verteilung des Kühlwassers auf der Brammenoberfläche bewirkt.If there are a plurality of intermediate rollers in a strand guide roller in the input or central region of the device for guiding continuous casting profiles, then it is advantageous if the signs of the gradients of the thread-shaped grooves on these intermediate rollers are chosen to be alternating. Then, a movement of the cooling water in a preferred direction transverse to the slab surface is not amplified, as would be the case if the signs on the idler rolls were all the same; instead By alternating the signs at the grooves of the intermediate roll advantageously a more even distribution of the cooling water is effected on the slab surface.

Derselbe Vorteil wird auch dadurch erzielt, dass bei zwei benachbarten Strangführungsrollen in dem Eingangs- oder Mittebereich der Vorrichtung zum Führen von Stranggussprofilen mit jeweils gleicher Anzahl von Zwischenrollen die Vorzeichen der Steigungen der gewindeförmigen Nuten von zwei in Brammenlaufrichtung hintereinander angeordneten Zwischenrollen entgegengesetzt gewählt sind.The same advantage is achieved by the fact that in two adjacent strand guide rollers in the input or middle region of the apparatus for guiding continuous casting profiles, each with the same number of intermediate roles, the signs of the pitches of the thread-like grooves of two consecutively arranged in the slab running direction intermediate roles are chosen.

Anders als im Eingangs- und Mittelbereich der Vorrichtung zum Führen von Stranggussprofilen ist es im Ausgangsbereich der Vorrichtung wünschenswert, dass das Kühlwasser so schnell wie möglich von der Brammenoberfläche abgeführt wird. Dies wird erfindungsgemäß dadurch erreicht, dass die entgegengesetzten Vorzeichen der Steigungen der gewindeförmigen Nuten auf den beiden äußeren Teilrollen so gewählt sind, dass die Kontaktbereiche der Nuten mit den Brammen bei einer Drehung der äußeren Teilrollen jeweils nach außen in Richtung linker und rechter Brammenrand wandern. Genauer gesagt bewirkt dann die linke Teilrolle ein Abführen des Kühlwassers über den linken Brammenrand und die rechte Teilrolle ein Abführen des Kühlwassers über den rechten Brammenrand.Unlike the entry and mid-section of the continuous casting guide, in the exit region of the device it is desirable for the cooling water to be removed from the slab surface as quickly as possible. This is inventively achieved in that the opposite signs of the pitches of the thread-shaped grooves on the two outer part rollers are chosen so that the contact areas of the grooves with the slabs migrate with a rotation of the outer part rollers each outwardly towards the left and right slab edge. More specifically, then causes the left part of the reel, a discharge of the cooling water over the left edge of the slab and the right part of the role, a discharge of the cooling water over the right edge of the slab.

Hat die Strangführungsrolle im Ausgangsbereich der Vorrichtung zum Führen von Stranggussprofilen mindestens eine Zwischenrolle, so ist es vorteilhaft, das Vorzeichen der Steigung der gewindeförmigen Nut auf der Zwischenrolle in einem Bereich links von der Brammenmitte entsprechend dem Vorzeichen der Steigung der Nut auf der linken äußeren Teilrolle, und in einem Bereich rechts von der Brammenmitte entsprechend dem Vorzeichen der Steigung der Nut auf der rechten äußeren Teilrolle, zu wählen. Das gilt insbesondere auch dann, wenn mehrere Zwischenrollen vorhanden sind, wobei dann das Vorzeichen der Steigungen der gewindeförmigen Nuten auf diesen mehreren Zwischenrollen in Abhängigkeit davon gewählt wird, ob die jeweiligen Zwischenrollen links oder rechts von der Brammenmitte angeordnet sind. Wichtig ist in diesem Fall lediglich, dass das Kühlwasser möglichst schnell abgeführt wird. Bei Vorhandensein einer ungeraden Anzahl von Zwischenrollen ist es vorteilhaft, wenn die eine Zwischenrolle im Bereich der Brammenmitte zwei getrennte gewindeförmige Nuten mit unterschiedlichen Vorzeichen ihrer Steigungen auf ihrer Oberfläche ausweist.If the strand guide roll has at least one intermediate roll in the exit area of the continuous casting guide, it is advantageous to have the sign of the pitch of the thread groove on the intermediate roll in an area to the left of the slab center corresponding to the sign of the slope of the groove on the left outer part roll. and in an area to the right of the slab center according to the sign of the slope of the groove on the right outer sub-roll. This is especially true when multiple intermediate rollers are present, in which case the sign of the pitches of the thread-shaped grooves is selected on these multiple intermediate roles depending on whether the respective intermediate rollers are located to the left or right of the slab center. It is important in this case only that the cooling water is removed as quickly as possible. In the presence of an odd number of intermediate roles, it is advantageous if the one intermediate role in the region of the slab center identifies two separate thread-like grooves with different signs of their slopes on their surface.

Ebenfalls anders als im Eingangs- oder Mittelbereich der Vorrichtung zum Führen von Stranggussprofilen ist es bei Strangführungsrollen im Ausgangsbereich der Vorrichtung vorteilhaft, die äußeren Teilrollen und vorzugsweise auch die Zwischenrollen hinsichtlich des Vorzeichens der Steigungen der Nuten auf ihren Oberflächen möglichst gleichartig auszubilden, um eine schnelle Kühlwasserabfuhr zu bewirken.Also, unlike in the input or central region of the device for guiding continuous casting profiles, it is advantageous for strand guide rollers in the exit region of the device to form the outer part rolls and preferably also the intermediate rolls as uniformly as possible with respect to the sign of the pitches of the grooves on their surfaces in order to achieve a fast cooling water drainage to effect.

Weitere vorteilhafte Ausgestaltungen der Vorrichtung zum Führen von Stranggussprofilen sind Gegenstand der Unteransprüche.Further advantageous embodiments of the device for guiding continuous casting profiles are the subject of the dependent claims.

These nozzles 112 provide cooling water for cooling the slabs. The strand guide rollers 130 serve to guide the slabs 200 through the apparatus (100) for guiding continuous casting profiles. In the apparatus, the slabs are seen in the running direction B L , an input region I, a middle region II and an output region III are distinguished.

Figur 2 zeigt den typischen Aufbau für eine erfindungsgemäße Strangführungsrolle 130, wie sie z.B. in der Vorrichtung (100) zum Führen von Stranggussprofilen verwendet wird. Demnach umfasst die Strangführungsrolle 130 zumindest eine linke äußere Teilrolle 130-L, welche dem linken Rand der Bramme 200 räumlich zugeordnet ist, und eine rechte Teilrolle 130-R, welche dem rechten Rand der Bramme 200 zugeordnet ist. Optional enthalten die Strangführungsrollen 130 darüber hinaus auch mehrere Zwischenrollen 130-M. FIG. 2 shows the typical structure for a strand guide roller 130 according to the invention, as used for example in the apparatus (100) for guiding continuous casting profiles. Accordingly, the strand guide roller comprises 130 at least one left outer sub-roll 130-L, which is spatially associated with the left edge of the slab 200, and a right sub-roll 130-R, which is associated with the right edge of the slab 200. Optionally, the strand guide rollers 130 also include a plurality of intermediate rollers 130-M.

Wie in Figur 2 zu erkennen ist, sind auf den Oberflächen von zumindest den beiden äußeren Teilrollen 130-L und 130-R jeweils gewindeförmige Nuten 132-L, 132-R mit entgegengesetztem Vorzeichen ausgebildet. Je nach Drehrichtung der Strangführungsrolle wird auf diese Weise eine Zusammenführung des Kühlwassers im Bereich der Brammenoberfläche oder ein Abführen des Kühlwassers von derselben bewirkt.As in FIG. 2 can be seen, are formed on the surfaces of at least the two outer part rollers 130-L and 130-R respectively thread-shaped grooves 132-L, 132-R with opposite signs. Depending on the direction of rotation of the strand guide roller, a merger of the cooling water in the region of the slab surface or a discharge of the cooling water is effected by the same in this way.

Wie weiterhin in Figur 2 zu erkennen ist, ist die Nut 132-M ebenfalls gewindeförmig ausgebildet, um die Ausbildung eines ortsfesten Wasserablaufkanals, wie er bei einer umlaufenden Nut ohne Steigung entstehen würde und eine daraus resultierende Streifenbildung auf der Brammenoberfläche zu vermeiden.As continues in FIG. 2 can be seen, the groove 132-M is also formed thread-shaped to avoid the formation of a stationary water drainage channel, as would occur in a circumferential groove without pitch and a resulting banding on the slab surface.

Im Eingangsbereich I und dem Mittelbereich II der Vorrichtung 100 sind die Vorzeichen der Steigungen der Nuten zwar entgegengesetzt, aber den äußeren Teilrollen 130-L, 130-R so zugeordnet, dass sie das verbleibende Kühlwasser, das heißt das Schwallwasser, auf der Brammenoberfläche halten bzw. dort zusammenführen. Um eine lokal überdurchschnittlich große Ansammlung von Schwallwasser im Mittelbereich der Brammen zu vermeiden, ist es empfehlenswert bei Vorhandensein mehrerer Zwischenrollen 130-M die Steigungen der gewindeförmigen Nuten auf diesen Zwischenrollen mit alternierenden Vorzeichen auszubilden.In the entrance area I and the central area II of the device 100, the signs of the slopes of the grooves are indeed opposite, but the outer part rollers 130-L, 130-R so assigned that they keep the remaining cooling water, that is, the splash water on the slab surface or merge there. In order to avoid a locally larger than average accumulation of splash water in the central region of the slabs, it is advisable to form in the presence of several intermediate rollers 130-M, the pitches of the thread-like grooves on these intermediate roles with alternating signs.

Figur 3 zeigt ein Segment von insgesamt 4 parallel angeordneten Strangführungsrollen 130, welche jeweils aus lediglich zwei Teilrollen, das heißt zwei äußeren Teilrollen 130-L, 130-R gebildet sind. Bei einer Bewegung der Brammen 200 in Brammenlaufrichtung BL ergibt sich aufgrund des Kontaktes der Teilrollen mit der Brammenoberfläche eine vordefinierte Drehrichtung der Teilrollen. Bei dieser Drehrichtung und der in Figur 3 gezeigten Ausbildung der Nuten 132-L, 132-R wird das Schwallwasser, wie von den horizontalen Pfeilen angedeutet, in Richtung Brammenmitte geführt. Grund dafür ist, dass sich die Kontaktbereiche K zwischen der Nut und der Brammenoberfläche ebenfalls in Richtung Brammenmitte, das heißt in Pfeilrichtung bewegen. Weil sowohl in dem Eingangsbereich I wie auch in dem Mittelbereich II eine möglichst große Kühlung der Brammen erreicht werden soll, ist es erforderlich, dass das Kühlwasser über die gesamte Länge der beiden Bereiche möglichst lange auf der Brammenoberfläche verbleibt. Um dies zu erreichen, ist es empfehlenswert, die Vorzeichen der Steigungen der gewindeförmigen Nuten von jeweils zwei in Brammenlaufrichtung BL hintereinander angeordneten äußeren Teilrollen gleichartig auszubilden, wie in Fig. 3 gezeigt. Sind Zwischenrollen vorhanden, empfiehlt sich bei in Bandlaufrichtung BL hintereinander angeordneten Zwischenrollen eine entgegengesetzte Ausbildung der Vorzeichen der Steigungen der Nuten auf deren Oberfläche um, wie gesagt, eine lokale Ansammlung von Schwallwasser auf einem bestimmten Bereich der Brammenoberfläche zu vermeiden. FIG. 3 shows a segment of a total of 4 parallel strand guide rollers 130, which are each formed from only two sub-rollers, that is, two outer sub-rollers 130-L, 130-R. During a movement of the slabs 200 in the slab running direction B L results due to the contact of the sub-rollers with the slab surface, a predefined direction of rotation of the sub-rollers. In this direction of rotation and in FIG. 3 shown formation of the grooves 132-L, 132-R, the splash water, as indicated by the horizontal arrows, out in the direction of slab center. The reason for this is that the contact areas K between the groove and the slab surface also move in the direction of the slab center, that is to say in the direction of the arrow. Because as large as possible cooling of the slabs should be achieved both in the entrance area I as well as in the central area II, it is necessary that the cooling water over the entire length of the two areas remains as long as possible on the slab surface. To achieve this, it is recommended that the signs of the pitches of the thread-like grooves of each two in the slab running direction B L successively arranged outer part rollers similar, as in Fig. 3 shown. If intermediate rollers are present, it is recommended that, when the intermediate rollers are arranged one behind the other in the direction of travel of the belt, an opposite formation of the signs of the inclinations of the grooves on their surface should be avoided, as stated, a local accumulation of splash water on a certain area of the slab surface.

Figur 4 zeigt die Fortsetzung der in Figur 3 bereits angedeuteten segmentartigen Zusammenschaltung von Strangführungsrollen im Mittelbereich II und im Endbereich III. Die Strangführungsrollen 130 im Mittelbereich II sind aus dem oben genannten Grund gleichartig profiliert wie die in Figur 3 gezeigten Strangführungsrollen bzw. deren Teilrollen. Die äußeren Teilrollen sind zwar in Bezug auf die Vorzeichen der Steigungen ihrer Nuten an ihrer Oberfläche entgegengesetzt ausgebildet; darüber hinaus ist jedoch das Vorzeichen der linken äußeren Teilrolle 130' auch entgegengesetzt zu dem Vorzeichen der Steigungsnuten auf der linken äußeren Teilrolle im Mittelbereich II ausgebildet. Gleiches gilt für die rechten äußeren Teilrollen im Außenbereich III und im Mittelbereich II. Auf diese Weise wird erreicht, dass die Strangführungsrollen 130', 130" im Ausgangsbereich III der Vorrichtung zum Führen von Stranggussprofilen das Schwallwasser möglichst schnell und effektiv von der Brammenoberfläche weg, nach Außen transportieren. FIG. 4 shows the continuation of in FIG. 3 already indicated segment-like interconnection of strand guide rollers in the middle region II and in the end III. The strand guide rollers 130 in the middle region II are similarly profiled as in the above-mentioned reason FIG. 3 shown strand guide rollers or their sub-rollers. Although the outer sub-rollers are opposite in shape with respect to the signs of the slopes of their grooves on their surface; moreover, however, the sign of the left outer part roller 130 'is also formed opposite to the sign of the slope grooves on the left outer part roller in the middle area II. The same applies to the right outer part rollers in the outer area III and in the central area II. In this way it is achieved that the strand guide rollers 130 ', 130 "in the output area III of the apparatus for guiding continuous casting profiles the splash water away from the slab surface as quickly and effectively as possible Transport outside.

In jedem Bereich I, II oder III der Vorrichtung 100 ist es empfehlenswert, dass die Verbindungsbereiche V bzw. die Lager zur Abstützung der Teilrollen in Brammenlaufrichtung BL bei zwei benachbarten Strangführungsrollen nicht fluchten, sondern versetzt angeordnet sind, wie dies in den Figuren 3 und 4 gezeigt ist; auf diese Weise wird die Ausbildung eines gradlinigen Schwallwasserablaufkanals mit Streifenwirkung auf der Brammenoberfläche verhindert.In each area I, II or III of the device 100, it is advisable that the connecting portions V and the bearings for supporting the sub-rollers in the slab running direction B L are not aligned with two adjacent strand guide rollers, but are arranged offset, as shown in the FIGS. 3 and 4 is shown; In this way, the formation of a straight-line surge water drainage channel with a strip effect on the slab surface is prevented.

Figur 5 zeigt ein Beispiel für die Ausbildung einer gewindeförmigen Nut 132 auf der Oberfläche eine Strangführungsrolle 130, das heißt insbesondere auf einer der beiden äußeren Teilrollen oder einer Zwischenrolle. Figur 5 zeigt konkret die Ausbildung einer eingängigen Nut, wobei Figur 5a eine Querschnittsansicht und Figur 5b eine Aufrissansicht zeigt. Weiterhin sind in Figur 5b die Kontaktbereiche K zwischen der Nut und der Oberfläche der Brammen 200 veranschaulicht. Wie gesagt, wandert dieser Kontaktbereich je nach Drehrichtung der Rolle zum linken oder rechten Rand der Bramme. FIG. 5 shows an example of the formation of a thread-shaped groove 132 on the surface of a strand guide roller 130, that is, in particular on one of the two outer part rollers or an intermediate roller. FIG. 5 shows concretely the formation of a catchy groove, wherein FIG. 5a a cross-sectional view and FIG. 5b an elevation view shows. Furthermore, in FIG. 5b the contact areas K between the groove and the surface of the slabs 200 are illustrated. As mentioned, this contact area moves depending on the direction of rotation of the roller to the left or right edge of the slab.

Die Figuren 6 und 7 zeigen Beispiel für die Anordnung von Nuten auf der Walzenoberfläche, wobei Figur 6 einen zweigängigen Nutenverlauf und Figur 7 einen dreigängigen Nutenverlauf beschreiben. Auch bei diesen beiden Figuren bezeichnen die Figuren a jeweils einen Querschnitt und die Figuren b jeweils eine Aufrissansicht der mehrgängigen Nuten.The FIGS. 6 and 7 show an example of the arrangement of grooves on the roll surface, wherein FIG. 6 a double-course groove course and FIG. 7 describe a three-course groove course. Also in these two figures, the figures a each indicate a cross-section and the figures b each show an elevational view of the multi-start grooves.

Allgemein wird die Anzahl der Nuten auf den äußeren Teilrollen 130-L, 130-R oder auf den Zwischenrollen sowie die Größe der jeweiligen Querschnitte der Nuten im Hinblick auf die Menge des abzuführenden Kühlwassers 120 und dessen gleichmäßige Verteilung auf der Brammenoberfläche gewählt. Weiterhin sind die Anzahl der parallelen gewindeförmigen Nuten pro Rolle, das heißt die Ganganzahl der Nuten, die Breiten der Nuten sowie deren Steigungen auf einer der äußeren Teilrollen oder einer Zwischenrolle 130-M im Verhältnis zum Rollendurchmesser und zur Rollenteilung so ausgeführt, dass eine geringe Überlappung der Kontaktbereiche K von zwei benachbarten gewindeförmigen Nuten auf einer Rolle mit jeweils der Brammenoberfläche stattfindet.In general, the number of grooves on the outer sub-rollers 130-L, 130-R or on the intermediate rollers and the size of the respective cross-sections of the grooves with respect to the amount to be discharged Cooling water 120 and its uniform distribution on the slab surface selected. Further, the number of parallel thread-like grooves per roll, that is, the number of flights of the grooves, the widths of the grooves and their pitches on one of the outer part rolls or an intermediate roll 130-M relative to the roll diameter and the roll pitch are made to have a small overlap the contact areas K of two adjacent thread-like grooves on a roll with the slab surface takes place.
