Abstract

The invention relates to a guide segment fitted with rollers on a continuous casting installation. In order to be able to accommodate as high mechanical loads as possible so as to accommodate the supporting force, at least some rollers are split up into three axially aligned roller bodies (4a, 5, 6). Only the outer roller bodies (4, 6) are axially fixed by means of their outer bearings designed as fixed bearings, whereas the middle roller body (5) is mounted in a floating manner. All the inner bearings (4b, 6a) of the outer roller bodies (4, 6) designed as movable bearings and the two bearings (8b, 9a) of the middle roller body are designed as movable bearings with high loading capacity, in particular as CARB bearings. The free axial mobility of the middle roller body (5) mounted in a floating manner is limited by stops (11, 12a, 12b, 13) designed as butting discs arranged between the end faces of the middle roller body (5) and the outer roller bodies (4, 6) lying opposite one another.

Description

Die Erfindung betrifft ein rollenbestücktes Führungssegment an einer Stranggießanlage, bei dem mindestens einige Rollen jeweils mindestens zwei fluchtende, mit endseitigen Rollenzapfen in Innen- und Außenlagern gelagerte Rollenkörper umfassen, wobei die Innenlager als Loslager in Form von vollrolligen Hochleistungslagern und die Außenlager als Festlager ausgebildet sind.The invention relates to a roll-loaded Guide segment on a continuous caster, in which at least some roles at least two each aligned, with roller ends on the inside and Include external bearings mounted roller body, the Bottom bracket as a floating bearing in the form of full complement High-performance bearings and the external bearings as fixed bearings are trained.

Rollenbestückte Führungssegmente an Stranggießanlagen dienen dazu, den aus der Kokille mit noch flüssigem Kern austretenden, bandförmigen Strang über einen Bogen aus der Vertikalen in die Horizontale zu überführen. Die dabei auftretende mechanische Belastung der Rollenlagerung ist groß, vor allem am Außenbogen der Führung. Deshalb ist es üblich, die Führungssegmente nicht mit sich über die gesamte Strangbreite erstreckenden, einteiligen Rollen zu bestücken, sondern mit mehrteiligen, insbesondere mit zwei fluchtenden Rollenkörpern. Da einerseits die Rollen axial fixiert gelagert sein müssen und andererseits Festlager, die diese Aufgabe erfüllen, eine geringere mechanische Belastung als nur in Form von Loslagern erhältliche vollrollige Hochleistungslager, wie z.B. CARB-Lager der Firma SKF, vertragen, ist man in jüngster Zeit bei der Bestückung von Führungssegmenten mit Rollen dazu übergegangen, jeweils zwei fluchtende Rollenkörper je Rolle einzusetzen, deren Außenlager als Festlager und deren Innenlager als Loslager in Form vollrolliger CARB-Lager ausgebildet sind. Mit der Ausbildung der Innenlager als spezielle Loslager wird der höheren Belastung der Rolle durch den Strang im Bereich der Strangmitte Rechnung getragen.Roller-mounted guide segments on continuous casting machines serve the from the mold with a still liquid core emerging, ribbon-shaped strand over an arch to convert the vertical to the horizontal. The mechanical stress that occurs Roller storage is large, especially on the outer arch of the Guide. That is why it is common for the leadership segments not with itself across the entire strand width extending, one-piece roles with multi-part, especially with two aligned Role bodies. Because on the one hand the rollers are axially fixed must be stored and on the other hand fixed bearings perform this task, a lower mechanical Load than only available in the form of floating bearings full complement high performance bearings, e.g. CARB warehouse of The SKF company, well tolerated, has been with the Equipping guide segments with roles passed, two aligned reel bodies each Use role, its external bearings as a fixed bearing and their bottom bracket as a floating bearing in the form of full complement CARB bearings are trained. With the formation of the bottom bracket as a special floating bearing the higher load of the Roll through the strand in the area of the middle of the strand Taken into account.

In den besonders stark mechanisch beanspruchten Bereichen der Bogenführung, insbesondere am Außenbogen, reichen vor allem bei verhältnismäßig breiten Strängen zwei fluchtende Rollenkörper je Rolle als Abstützung des Stranges nicht aus. Deshalb hat man in der Vergangenheit in diesen Bereichen drei miteinander fluchtende Rollenkörper je Rolle eingesetzt (s. z.B. JP 60 141 356, Basis des Kennzeichnenden Teils der Ansprüche. Da aber die mechanisch höher belastbaren vollrolligen Hochleistungslager nur eine beschränkte axiale Relativverschiebung ihrer Laufringe vertragen und deshalb bei zwei fluchtend angeordneten Rollenkörpern jeder Rollenkörper an einem Ende mit einem Festlager axial fixiert ist, würde die Anwendung des Lagerprinzips "je Rollenkörper ein Festund ein Loslager" für den mittleren Rollenkörper wegen der geringeren Belastbarkeit des Festlagers nicht zum gewünschten Erfolg einer insgesamt höheren Belastbarkeit der Rolle führen.In the areas with particularly high mechanical stress the arch guidance, especially on the outer arch, is sufficient especially with relatively wide strands two aligned roll body per roll to support the Stranges not out. That's why you have in the past three in alignment in these areas Roll body used per roll (see e.g. JP 60 141 356, basis of the characterizing part of the claims. But since the mechanical heavy duty full complement high performance bearings only a limited axial relative displacement of their Tolerate races and therefore in alignment with two arranged roller bodies each roller body on one Is fixed axially with a fixed bearing, the Application of the bearing principle "one fixed and one for each reel body a floating bearing "for the middle roller body the lower resilience of the fixed bearing not desired success of an overall higher resilience the role.

Der Erfindung liegt die Aufgabe zugrunde, ein rollenbestücktes Führungssegment an einer Stranggießanlage zu schaffen, das im Vergleich zu einem Führungssegment mit jeweils zwei Rollenkörpern je Rolle mechanisch höher belastbar ist.The invention is based on the object role-equipped guide segment on one Continuous caster to create that compared to one Guide segment with two reel bodies per reel is mechanically more resilient.

Diese Aufgabe wird erfindungsgemäß bei einem Führungssegment der eingangs genannten Art dadurch gelöst, daß zwischen den beiden Rollenkörpern und mit ihnen fluchtend ein weiterer Rollenkörper mit seinen beiden endseitigen Rollenzapfen in Loslagern in Form von vollrolligen Hochleistungslagern axial schwimmend gelagert ist, wobei die freie axiale Beweglichkeit des mittleren Rollenkörpers durch zwischen den innenliegenden Rollenzapfen der äußeren Rollenkörper und den beiden Rollenzapfen des mittleren Rollenkörpers wirksame Anschläge begrenzt ist.This object is achieved with one Leading segment of the type mentioned solved that between the two roller bodies and with another roller body in alignment with his two end roller journals in floating bearings in the form of full complement high performance bearings axially floating is mounted, the free axial mobility of the middle roller body through between the inner Roller journal of the outer roller body and the two Effective roller journal of the middle roller body Attacks is limited.

Bei dem erfindungsgemäßen Führungssegment wird die höhere Belastbarkeit der mindestens dreiteiligen Rolle dadurch erreicht, daß im mittleren Abstützbereich des Stranges, wo die Rolle die größte Stützkraft aufbringen muß, nur die hoch belastbaren vollrolligen Loslager zum Einsatz kommen. Zur Zeit kommen dafür die am Markt erhältlichen, sogenannten CARB-Lager der Firma SKF in Betracht. Es ist aber denkbar, daß andere von der Belastbarkeit vergleichbare Loslager zum Einsatz kommen können. Die für diese Loslager beschränkt zulässige axiale Beweglichkeit wird ausschließlich durch die außenliegenden Festlager der äußeren Rollenkörper begrenzt. Bei den äußeren Rollenkörpern geschieht dies unmittelbar über deren äußere Festlager und bei dem mittleren Rollenkörper über die Anschläge an den axial festgelegten äußeren Rollenkörpern.In the guide segment according to the invention, the higher one Resilience of the at least three-part role achieves that in the middle support area of the strand, where the role has to provide the greatest support, only the highly resilient full complement floating bearings are used come. At the moment there are available on the market so-called CARB bearings from SKF. It is but conceivable that others of resilience comparable floating bearings can be used. The for this floating bearing limits the permissible axial mobility is only due to the external fixed bearings the outer roller body is limited. With the outer Role bodies do this directly via their outer fixed bearing and the middle roller body over the stops on the axially fixed outer Role bodies.

Vorzugsweise sind, wie an sich bekannt, die Festlager Pendelrollenlager.As is known per se, the fixed bearings are preferably Spherical roller bearings.

Konstruktiv läßt sich die axiale Beweglichkeit des mittleren Rollenkörpers dadurch begrenzen, daß die beiden inneren Rollenzapfen der äußeren Rollenkörper und/oder die Rollenzapfen des mittleren Rollenkörpers an ihren Stirnseiten Anlaufscheiben tragen, die das axiale Spiel des mittleren Rollenkörpers derart begrenzen, daß es im kalten Zustand der Rollenkörper ≤ der zulässigen axialen Beweglichkeit der Loslager des mittleren Rollenkörpers und > als die Summe der maximalen axialen Wärmeausdehnung der Rollenkörper ist.The axial mobility of the limit the middle roller body in that the two inner roller journal of the outer roller body and / or the roller journals of the middle roller body on theirs Face thrust washers that support the axial play limit the middle roller body so that it is in cold condition of the roller body ≤ the permissible axial Mobility of the floating bearings of the middle roller body and> as the sum of the maximum axial thermal expansion is the reel body.

Um bei Betriebstemperatur die Rollen optimal gelagert zu haben, ist nach einer Ausgestaltung der Erfindung vorgesehen, daß die Lagerringe der Loslager der äußeren Rollenkörper in deren kaltem Zustand zueinander derart axial versetzt sind, daß sie sich im betriebswarmen Zustand in ihrer optimalen Lagerstellung befinden.In order to optimally store the rollers at operating temperature have, according to an embodiment of the invention provided that the bearing rings of the floating bearing of the outer Roll body in their cold state to each other like this are axially offset that they are in the warm operating condition Condition in their optimal storage position.

Im folgenden wird die Erfindung anhand einer ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert. Im einzelnen zeigen:

and

In der Stranggießanlage nach Figur 1 wird ein in einer Kokille 1 gegossener bandförmiger Strang 2 mit einer aus Führungssegmenten 3a,3b gebildeten Bogenführung 3 aus der Vertikalen in die Horizontale umgelenkt. Die einzelnen Führungssegmente 3a,3b stützen dabei den Strang 2 an seinen Breitseiten mit Rollen ab. Dabei müssen die Rollen die größte Stützkraft im mittleren Bereich des Stranges aufbringen. Eine dieser Rollen, zum Beispiel eine der am Außenbogen der Bogenführung 3 angeordnete Rolle, ist in Figur 2 im einzelnen dargestellt.In the continuous casting installation according to FIG. 1, one in one Chill mold 1 cast ribbon-shaped strand 2 with one Guide segments 3a, 3b formed sheet guide 3 from the Redirected the vertical to the horizontal. The single ones Guide segments 3a, 3b support the strand 2 its broadsides with roles. The roles the greatest supporting force in the middle area of the strand muster. One of these roles, for example one of the am Outer bow of the sheet guide 3 arranged role is in Figure 2 shown in detail.

Die Rolle gemäß Figur 2 besteht aus drei fluchtend angeordneten Rollenkörpern 4,5,6, die jeweils mit endseitigen Rollenzapfen 4a,4b,5a,5b,6a,6b in Wälzlagern 7a,8a,8b,9a,9b,10a gelagert sind, die von Lagerböcken 7,8,9,10 des Führungssegmentes 3b getragen sind. Die äußeren Lager 7a,10a der beiden äußeren Rollenkörper 4,6 sind als Festlager ausgebildet, während alle übrigen Lager 8a,8b,9a,9b als Loslager ausgebildet sind.The role of Figure 2 consists of three in alignment arranged roller bodies 4,5,6, each with end roller pin 4a, 4b, 5a, 5b, 6a, 6b in rolling bearings 7a, 8a, 8b, 9a, 9b, 10a are supported by bearing blocks 7,8,9,10 of the guide segment 3b are worn. The outer bearings 7a, 10a of the two outer roller bodies 4, 6 are designed as fixed bearings, while all others Bearings 8a, 8b, 9a, 9b are designed as floating bearings.

Die beiden Festlager 7a,10a sind herkömmliche Pendelrollenlager, über die die Lagerzapfen 4a,6b gegenüber ihren Lagerböcken 7,10 im Führungssegment axial fixiert sind. Alle anderen Lager 8a,8b,9a,9b sind als spezielle hochbelastbare Loslager ausgebildet. Insbesondere sind es vollrollige Rollenlager mit leicht balligen Rollen geeignet, die bei vergleichsweise hoher Tragfähigkeit in der Lage sind, Schiefstellungen und Axialverschiebungen auszugleichen. Diesen Qualitätsansprüchen genügen zur Zeit beispielsweise CARB-Lager der Firma SKF. So kann sich bei den Loslagern 8a,8b,9a,9b des Ausführungsbeispiels der innere Lagerring auf dem Rollenzapfen 4b,5a,5b,6a gegenüber dem im Lagerbock 8,9 fixierten äußeren Lagerring axial verschieben und schiefstellen.The two fixed bearings 7a, 10a are conventional Spherical roller bearings via which the journals 4a, 6b compared to their bearing blocks 7.10 in the guide segment axially are fixed. All other bearings 8a, 8b, 9a, 9b are as special heavy-duty floating bearings designed. In particular, there are full complement roller bearings with light weight crowned rollers suitable at comparatively high Are capable of misalignment and Compensate for axial displacements. this Quality requirements, for example, currently satisfy CARB bearings from SKF. So can the loose bearings 8a, 8b, 9a, 9b of the embodiment of the inner bearing ring on the roller pin 4b, 5a, 5b, 6a compared to the im Bearing block 8.9 fixed outer bearing ring axially move and skew.

Da der mittlere Rollenkörper 5 mit beiden Rollenzapfen 5a,5b in Loslagern 8b,9a gelagert ist, ergibt sich für den Rollenkörper 5 eine schwimmende Lagerung. Die axiale Beweglichkeit dieses schwimmend gelagerten Rollenkörpers 5 muß begrenzt sein, damit die Loslager 8b,9a nicht durch zu große axiale Verschiebung überlastet werden. Zu diesem Zweck tragen die einander zugekehrten Stirnseiten der Lagerzapfen 4b, 5a, 5b, 6a angeschraubte Anlaufscheiben 11,12a,12b,13. In der Zeichnung ist der Ausgangszustand bei kalten Rollenkörpern 4,5,6 dargestellt. Wie zu erkennen ist, haben die einander zugewandten Anlaufscheiben 11,12a,12b,13 einen bestimmten axialen Abstand zueinander. Dieser ist so bemessen, daß der schwimmend gelagerte Rollenkörper 5 in die eine oder andere axiale Richtung nur um einen Weg verlagert werden kann, der höchstens gleich der maximal zulässigen axialen Verschiebung für seine Loslager ist. Er ist aber ausreichend groß, um die zu erwartende maximale axiale Verschiebung der Rollenkörper 4,5,6 mit ihren Rollenzapfen 4a,5a,5b,6b infolge von thermischen Ausdehnungen aufnehmen zu können. Es versteht sich, daß durch gezielte Kühlung der Rollenkörper ihre Wärmeausdehnung beeinflußt, vor allem in bestimmten Grenzen gehalten werden kann.Since the middle roller body 5 with both roller journals 5a, 5b in floating bearings 8b, 9a results for the roller body 5 a floating storage. The axial Mobility of this floating roller body 5 must be limited so that the floating bearings 8b, 9a are not excessive axial displacement can be overloaded. To this The end faces of the Bearing pins 4b, 5a, 5b, 6a screwed thrust washers 11,12a, 12b,. 13 In the drawing is the initial state shown with cold roller bodies 4,5,6. How to is recognizable, they face each other Thrust washers 11, 12a, 12b, 13 a certain axial Distance from each other. This is dimensioned so that the floating roller body 5 in one or other axial direction can be shifted only one way can, which is at most equal to the maximum permissible axial Shift for its floating bearing is. But he is sufficiently large to allow the maximum axial to be expected Displacement of the roller body 4,5,6 with their Roller pin 4a, 5a, 5b, 6b due to thermal To be able to absorb extensions. It is understood that through targeted cooling of the roller body Thermal expansion affects, especially in certain Limits can be kept.

Außerdem ist der Darstellung der Figur 3, die die Einbausituation im kalten Zustand der Rollenkörper 4,5,6 zeigt, zu entnehmen, daß die Lagerringe des inneren Loslagers 8a des äußeren Rollenkörpers 4 gegeneinander um ein bestimmtes Maß axial versetzt sind. Bei den Lagerringen des Loslagers 9b des in Figur 3 nicht dargestellten anderen Rollenkörpers 6 ist ein entsprechender axialer Versatz vorgesehen. Dieser axiale Versatz ist so bemessen, daß bei betriebswarmen Rollenkörpern 4,6 sich die Lagerringe der Loslager 8a,9b in ihrer optimalen Lagerposition zueinander befinden.In addition, the representation of Figure 3, the Installation situation in the cold state of the roller body 4,5,6 shows that the bearing rings of the inner Floating bearing 8a of the outer roller body 4 against each other are axially offset by a certain amount. Both Bearing rings of the floating bearing 9b of the in Figure 3 is not shown other roller body 6 is a corresponding axial offset is provided. This axial The offset is such that when the Roller bodies 4.6, the bearing rings of the floating bearings 8a, 9b are in their optimal storage position to each other.
