Description

Die Erfindung betrifft eine Einrichtung zum Vermessen zweier einander gegenüberliegender Rollenbahnen einer Stranggießanlage, mit einem durch das Profil zwischen den Rollenbahnen hindurchbewegbaren Meßkörper, der einander gegenüberliegende, die Mantelflächen der Rollen berührende Kontaktflächen aufweist, die aus elastisch verformbaren Federbändern, insbesondere Federstahlbändern, gebildet sind, wobei die Kontaktflächen durch zwischen ihnen angeordnete Druckmittel an die Mantelflächen der Rollen preßbar sind.The invention relates to a device for measuring two opposing roller conveyors of a continuous casting installation, with a measuring body which can be moved through the profile between the roller conveyors and which has opposing contact surfaces which contact the lateral surfaces of the rollers and which are formed from elastically deformable spring strips, in particular spring steel strips, whereby the contact surfaces can be pressed against the lateral surfaces of the rollers by pressure means arranged between them.

Eine Einrichtung dieser Art ist aus der EP O 028 215 A1 bekannt. Mit dieser Einrichtung kann die Distanz zweier einander gegenüberliegender Rollenbahnen exakt festgestellt werden, wobei es auch möglich ist, die Distanz der Rollenbahnen auch bei einander nicht genau gegenüberliegend angeordneten Rollen und bei Rollenbahnen mit über ihre Längserstreckung unterschiedlichen Rollenteilungen und mit sich ändernden Krümmungsverhältnissen einwandfrei zu vermessen.A device of this type is known from EP O 028 215 A1. With this device, the distance between two opposing roller conveyors can be exactly determined, it is also possible to measure the distance of the roller conveyors even when the rollers are not arranged exactly opposite one another and in the case of roller conveyors with different roller partitions over their longitudinal extent and with changing curvature conditions.

Die Erfindung stellt sich die Aufgabe, eine Einrichtung dieser Art in der Weise auszubilden, daß sie zum Vermessen von Rollenbahnen verwendet werden kann, bei denen zwar die Rollendistanz der einander gegenüberliegenden Rollen exakt stimmt, jedoch einzelne oder mehrere Rollenpaare gegenüber anderen Rollenpaaren versetzt angeordnet sind.The invention has for its object to design a device of this type in such a way that it can be used for measuring roller conveyors in which the roller distance of the opposing rollers is exactly correct, but one or more pairs of rollers are offset from other pairs of rollers.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an mindestens einem der Federbänder eine sich im wesentlichen in Bewegungsrichtung der Einrichtung erstreckende Distanzänderungs-Meßeinrichtung vorgesehen ist. Dadurch ist es möglich, eine Längenänderung eines der Federbänder, wie sie bei Durchgang der Meßeinrichtung durch zueinander versetzte Rollenpaare auftritt, festzustellen und Rollenbahnversetzungen, wie sie insbesondere bei aus einzelnen Segmenten zusammengesetzten Rollenbahnen auftreten können, aufzuspüren.This object is achieved in that a distance change measuring device extending essentially in the direction of movement of the device is provided on at least one of the spring bands. This makes it possible to determine a change in length of one of the spring bands, as occurs when the measuring device passes through mutually offset pairs of rollers, and to detect roller track displacements, as can occur, in particular, in the case of roller tracks composed of individual segments.

Gemäß einer bevorzugten Ausführungsform ist an beiden Federbändern mindestens je eine Distanzänderungs-Meßeinrichtung vorgesehen, die einander senkrecht zur Bewegungsrichtung der Einrichtung gegenüberliegen. Dadurch ist es möglich, einen Rollenpaarversatz mit einem einzigen Durchgang der Einrichtung durch die Rollenbahnen eindeutig von einem Distanzfehler nur einer Rolle der Rollenbahneαzu unterscheiden.According to a preferred embodiment, at least one distance change measuring device is provided on each of the two spring bands, which is opposite one another perpendicular to the direction of movement of the device. This makes it possible to clearly differentiate a pair of rollers offset with a single passage of the device through the roller conveyors from a distance error of only one roller of the roller conveyor α.

Vorteilhaft ist jede Distanzänderungs-Meßeinrichtung zwischen zwei an dem Federband innenseitig montierten Halterungen eingesetzt, wobei zweckmäßig mindestens eine der Halterungen als etwa senkrecht zur Kontaktfläche der Federbänder gerichtete Konsole ausgebildet ist, die bis in die Nähe des gegenüberliegenden Federbandes verlängert ausgebildet ist, und wobei weiters die Distanzänderungs-Meßeinrichtung zwischen dem Ende der Konsole und einer weiteren Halterung eingesetzt ist.Each distance change measuring device is advantageously inserted between two brackets mounted on the inside of the spring band, whereby at least one of the brackets is expediently designed as a console oriented approximately perpendicular to the contact surface of the spring bands, which is extended to the vicinity of the opposite spring band, and furthermore the Distance change measuring device is inserted between the end of the console and another bracket.

Als für den rauhen Stahlwerksbetrieb besonders geeignet haben sich bei der erfindungsgemäßen Einrichtung induktive Weggeber gezeigt.Inductive displacement sensors have been shown to be particularly suitable for the rough steelworks operation in the device according to the invention.

Für besonders genaue Messungen werden zweckmäßig auf das Federband aufgebrachte Dehnmeßstreifen verwendet.Strain gauges attached to the spring band are used for particularly precise measurements.

Die Erfindung ist nachfolgend anhand der Zeichnung an zwei Ausführungsbeispielen näher erläutert, wobei die Fig. 1 bis 4 eine erfindungsgemäße Einrichtung in schematischer Darstellung in Seitenansicht zwischen zwei Rollenbahnen zeigen. In Fig. 5 ist eine weitere Ausführungsform der erfindungsgemäßen Einrichtung dargestellt.The invention is explained in more detail below with reference to the drawing using two exemplary embodiments, with FIGS. 1 to 4 showing a device according to the invention in a schematic representation in a side view between two roller conveyors. 5 shows a further embodiment of the device according to the invention.

Zwischen den Rollenbahnen 1 und 2 einer Strangführung einer Stranggießanlage ist die Einrichtung 3 zum Vermessen der Rollenbahnen eingeschoben. Zweckmäßig weist die Einrichtung ein nicht dargestelltes Kupplungsstück auf, mit dem sie mittels einer Kupplung an einem Anfahrstrangkopf eines Anfahrstranges zum Zweck des Durchziehens zwischen den Rollenbahnen 1 und 2 befestigbar ist.The device 3 for measuring the roller tracks is inserted between the roller tracks 1 and 2 of a strand guide of a continuous casting plant. The device expediently has a coupling piece (not shown), by means of which it can be fastened by means of a coupling to a starting strand head of a starting strand for the purpose of pulling between the roller tracks 1 and 2.

Die Einrichtung weist zwei mit den Mantelflächen 4 der Rollen 5 in Kontakt gelangende Kontaktflächen 6 auf, die an der Außenseite von elastisch verformbaren Federbändern 7, wie Federstahlbändern, liegen. Die Federstahlbänder werden durch zwischen ihnen angeordnete Druckmittel 8, beispielsweise durch Federtöpfe oder hydraulische bzw. pneumatisch beaufschlagte Druckmittel an die Mantelflächen 4 der Rollen 5 angepreßt. Die Entfernung 9 der Druckmittel 8 in Längsrichtung 10 der Rollenbahnen bzw. in Bewegungsrichtung 11 der Einrichtung entspricht etwa dem Abstand 12 der Achsen 13 der Rollen 5. Da bei Stranggießanlagen knapp unterhalb der Kokille die Achsen 13 der Rollen 5 eng benachbart, hingegen beim auslaufseitigen Ende der Anlage in größeren Distanzen liegen, wählt man hier zweckmäßig einen Mittelwert.The device has two contact surfaces 6 which come into contact with the lateral surfaces 4 of the rollers 5 and which lie on the outside of elastically deformable spring bands 7, such as spring steel bands. The spring steel strips are pressed against the lateral surfaces 4 of the rollers 5 by pressure means 8 arranged between them, for example by spring pots or hydraulic or pneumatically actuated pressure means. The distance 9 of the pressure medium 8 in the longitudinal direction 10 of the roller conveyors or in the direction of movement 11 of the device corresponds approximately to the distance 12 of the axes 13 of the rollers 5. Since in continuous casting systems just below the mold, the axes 13 of the rollers 5 are closely adjacent, on the other hand at the outlet end If the system is at greater distances, an average value should be chosen.

An der Innenseite 14 jedes Federstahlbandes 7 sind mit dem Federstahlband starr verbundene Halterungen 15 vorgesehen, zwischen die eine sich im wesentlichen in Bewegungsrichtung 11 der Einrichtung 3 erstreckende Distanzänderungs-Meßeinrichtung 16 eingesetzt ist. Die in den Figuren veranschaulichte Distanzänderungs-Meßeinrichtung 16 ist als induktiver Weggeber ausgebildet. Die Halterungen 15 sind als etwa senkrecht zur Kontaktfläche der Federbänder gerichtete Konsolen ausgebildet, an denen die Distanzänderungs-Meßeinrichtungen 16 spielfrei angelenkt sind. Die Distanz 17 der Halterungen 15 entspricht etwa dem Abstand 12 der Achsen 13 der Rollen 5 einer der Rollenbahnen 1, 2, wobei auch hier wiederum zweckmäßig ein Mittelwert sämtlicher Abstände der Rollenachsen einer Strangführungsbahn als Halterungsdistanz 17 gewählt wird.On the inside 14 of each spring steel strip 7, brackets 15 are provided which are rigidly connected to the spring steel strip and between which a distance which extends essentially in the direction of movement 11 of the device 3 change measuring device 16 is used. The distance change measuring device 16 illustrated in the figures is designed as an inductive displacement sensor. The brackets 15 are designed as brackets directed approximately perpendicular to the contact surface of the spring strips, on which the distance change measuring devices 16 are articulated without play. The distance 17 of the brackets 15 corresponds approximately to the distance 12 of the axes 13 of the rollers 5 of one of the roller tracks 1, 2, again a mean value of all the distances of the roller axes of a strand guide track being selected as the holding distance 17.

Wie Fig. 2 erkennen läßt, ist mit der erfindungsgemäßen Einrichtung, die beispielsweise an eine Einrichtung gemäß der EP O 028 215 A1 ankuppelbar ist, auch ein Rollenversatz 18 eruierbar, obwohl die Distanz 19 der einander gegenüberliegenden Rollen bei allen Rollen 5 genau dem Idealmaß entspricht.As can be seen in FIG. 2, with the device according to the invention, which can be coupled, for example, to a device according to EP O 028 215 A1, a roller offset 18 can also be determined, although the distance 19 of the opposing rollers corresponds exactly to the ideal dimension for all rollers 5 .

Mit der erfindungsgemäßen Einrichtung läßt sich aber nicht nur ein Rollenversatz 18, sondern wie aus den Fig. 3 und 4 entnommen werden kann, auch ein Versatz 20 einer einzelnen Rolle (Fig. 3) sowie der Krümmungsradius 21 einer Rollenbahn feststellen und vermessen.With the device according to the invention, however, not only a roller offset 18 but, as can be seen from FIGS. 3 and 4, also an offset 20 of an individual roller (FIG. 3) and the radius of curvature 21 of a roller conveyor can be determined and measured.

Gemäß der in Fig. 5 dargestellten Ausführungsform sind die Halterungen 22 als in Richtung senkrecht zur Kontaktfläche 6 eines Federstahlbandes 7 gerichtete Konsolen ausgebildet, die bis in die Nähe des gegenüberliegenden Federstahlbandes 7 ragen. Die Distanzänderungs-Meßeinrichtung ist zwischen den Enden 23 der Konsolen 22 eingesetzt. Infolge der Länge 24 der Konsolen wird die Distanzänderung durch die Distanzänderungs-Meßeinrichtung 16 verstärkt angezeigt, so daß die Einrichtung 3 mit einer sehr großen Genauigkeit arbeitet.According to the embodiment shown in FIG. 5, the brackets 22 are designed as brackets directed in the direction perpendicular to the contact surface 6 of a spring steel strip 7 and projecting into the vicinity of the opposite spring steel strip 7. The distance change measuring device is inserted between the ends 23 of the brackets 22. Due to the length 24 of the brackets, the change in distance is increasingly displayed by the distance change measuring device 16, so that the device 3 operates with a very high degree of accuracy.

Anstelle des zwischen den Halterungen 15 bzw. Konsolen 22 eingesetzten induktiven Weggebers 16 kann auch direkt auf das Federstahlband 7 ein Dehnmeßstreifen aufgebracht, beispielsweise aufgeklebt werden, wobei die Längsrichtung des Dehnmeßstreifens parallel zur Bewegungsrichtung 11 der Meßeinrichtung 3 gerichtet ist.Instead of the inductive displacement sensor 16 inserted between the brackets 15 or brackets 22, a strain gauge can also be applied, for example glued, directly to the spring steel strip 7, the longitudinal direction of the strain gauge being directed parallel to the direction of movement 11 of the measuring device 3.

In den Fig. 1 bis 5 sind parallel zu den die Kontaktflächen 6 der Federstahlbänder 7 an die Mantelflächen 4 der Rollen 5 pressenden Druckmitteln 8 weitere Distanzänderungs-Meßeinrichtungen 25 vorgesehen, die dazu dienen, die Distanz 19 der Rollenbahnen 1, 2 zu bestimmen, u.zw. in der Weise, wie es in der EP O 028 215 A1 beschrieben ist. Diese Distanzänderungs-Meßeinrichtungen sind mit strichlierten Linien dargestellt, da sie für die erfindungsgemäße Einrichtung 3 nicht unbedingt erforderlich sind.1 to 5 parallel to the contact surfaces 6 of the spring steel strips 7 on the lateral surfaces 4 of the rollers 5 pressing means 8 further distance change measuring devices 25 are provided, which serve to determine the distance 19 of the roller tracks 1, 2, u .zw. in the manner described in E PO 028 215 A 1. These distance change measuring devices are shown with dashed lines since they are not absolutely necessary for the device 3 according to the invention.

Die Erfindung ist nicht auf das dargestellte Ausführungsbeispiel beschränkt, sondern kann in verschiedener Hinsicht modifiziert werden. So ist es beispielsweise möglich, die Distanzänderungs-Meßeinrichtung 16 schräg, d.h. unter einem Winkel zur Bewegungsrichtung geneigt in der Einrichtung vorzusehen, indem lediglich eine der beiden Konsolen 22 (Fig. 5) bis in die Nähe des gegenüberliegenden Federstahlbandes 7 verlängert ausgebildet ist.The invention is not limited to the exemplary embodiment shown, but can be modified in various ways. For example, it is possible to incline the distance change measuring device 16, i.e. to be provided inclined at an angle to the direction of movement in the device, in that only one of the two brackets 22 (FIG. 5) is extended to the vicinity of the opposite spring steel strip 7.

Wesentlich für die Erfindung ist, daß die Distanzänderungs-Meßeinrichtung 16 stets eine Distanzänderung zwischen zwei in Bewegungsrichtung 11 im Abstand voneinander liegenden Punkten eines der Federstahlbänder 7 feststellt bzw. mißt.It is essential for the invention that the distance change measuring device 16 always detects or measures a distance change between two points of one of the spring steel strips 7 which are spaced apart in the direction of movement 11.

Damit die Federstahlbänder 7 genau der Krümmung 21 der Rollenbahnen folgen können, müssen die Federstahlbänder 7 mindestens eine dem dreifachenAbstand 12 zweier benachbarter Rollen 5 entsprechende Länge 26 aufweisen, so daß jedes Federstahlband 7 mit mindestens drei Rollen 5 einer Rollenbahn 1 bzw. 2 in Kontakt steht. Es ist von Vorteil, wenn ein den Meßschrieb der Distanzänderungs-Meßeinrichtung 16 aufzeichnendes Schreibgerät an einem am Kupplungsstück montierten Kasten angeordnet ist. Es ist jedoch auch möglich, die Meßwerte mittels Schleppkabel oder auch drahtlos per Funk nach außen durchzugeben.In order that the spring steel strips 7 can exactly follow the curvature 21 of the roller tracks, the spring steel strips 7 must be at least one three times the distance 12 between two beard rollers 5 have a corresponding length 26, so that each spring steel strip 7 is in contact with at least three rollers 5 of a roller conveyor 1 or 2. It is advantageous if a writing instrument recording the measurement record of the distance change measuring device 16 is arranged on a box mounted on the coupling piece. However, it is also possible to transmit the measured values to the outside using a trailing cable or wirelessly by radio.
