Description

Die Erfindung betrifft eine Bandbehandlungsanlage zum Richten von Metallbändern, insbesondere Edelstahlbändern. Bei den Edelstahlbändern kann es sich insbesondere um kaltgewalzte, geglühte und gebeizte bzw. blankgeglühte und nichtrostende Edelstahlbänder handeln.The invention relates to a belt treatment plant for Straightening metal strips, especially stainless steel strips. The stainless steel strips can in particular be cold-rolled, annealed and pickled or bright annealed and trade stainless steel strips.

Es ist eine derartige Bandbehandlungsanlage mit einem Dressiergerüst und einer nachgeschalteten ein- oder mehrzonigen Zugreckanlage bekannt. Zwischen einem eine Reckzone bildenden Zugreckrollenpaar und dem Dressiergerüst ist ein Spannrollensatz angeordnet, mit dem der Bandzug vom Niveau des Dressierzuges auf das Niveau der Zugreckung gesteigert wird. Diese Maßnahmen haben sich in der Praxis bewährt. Grundsätzlich besteht aber bei Bandbehandlungsanlagen im Bereich jeder einzelnen Rolle das Risiko einer Beschädigung der Bandoberfläche. Hier setzt die Erfindung ein.It is such a belt treatment plant with one Skin pass mill and a downstream single or multi-zone Train stretching unit known. A stretching zone between you forming drawstring roller pair and the skin pass mill is a Tension roller set arranged with which the belt pull from level of the skin pass is increased to the level of stretching becomes. These measures have proven themselves in practice. Basically, however, in the case of strip treatment plants Area of each individual role the risk of damage the belt surface. This is where the invention comes in.

Der Erfindung liegt die Aufgabe zugrunde, eine Bandbehandlungsanlage zum Richten von Metallbändern der eingangs beschriebenen Art zu schaffen, mit welcher sich nicht nur eine hohe Planheit der zu richtenden Bänder erzielen lässt, sondern bei welcher zu dem das Risiko einer Beschädigung der Bandoberfläche minimiert ist.The invention has for its object a belt treatment plant for straightening metal strips at the beginning described way of creating, with which not only achieve a high level of flatness of the strips to be straightened leaves, but at which the risk of a Damage to the belt surface is minimized.

Zur Lösung dieser Aufgabe lehrt die Erfindung eine Bandbehandlungsanlage zum Richten von Metallbändern, insbesondere Edelstahlbändern, mit einem Dressiergerüst und zumindest einem dem Dressiergerüst unmittelbar nachgeordneten und aus zumindest zwei Spannrollen bestehenden Zugreckrollenpaar, wobei zwischen dem Dressiergerüst und der ersten Spannrolle des Zugreckrollenpaares eine Vorreckzone und zwischen der ersten und der zweiten Spannrolle des Zugreckrollenpaares eine erste Nachreckzone verwirklicht sind. Dabei kann die Vorreckzone entweder für eine elastische Reckung des Bandes bis nahezu zur Elastizitätsgrenze oder für eine plastische oder elastoplastische bzw. semiplastische Reckung ausgelegt sein. In der Nachreckzone erfolgt eine plastische oder elastoplastische Reckung des Bandes. Insofern wird der Bandzug auslaufseitig des Dressiergerüstes soweit angehoben, dass bereits zwischen dem Dressiergerüst und der ersten Spannrolle des Zugreckrollenpaares eine Reckzone in Form einer Vorreckzone realisiert ist. Auf einen zusätzlichen Spannrollensatz zum Steigern des Bandzuges vom Niveau des Dressierzuges auf das Niveau der Zugreckung kann daher vollständig verzichtet werden. Durch diese Maßnahme wird die Spannrollenzahl reduziert und wegen der geringeren Spannrollenzahl nicht nur das Risiko von Beschädigungen der Bandoberfläche verringert, sondern darüber hinaus werden auch in erheblichem Maße Kosten reduziert, weil die Zahl der Spannrollen bzw. S-Rollen geringer ist als bei vergleichbaren Anlagen. Überraschenderweise geht der Verzicht auf einen Spannrollensatz zwischen Dressiergerüst und Zugreckrollensatz nicht zu Lasten der erzielbaren Planheit. Vielmehr lassen sich mit der erfindungsgemäßen Bandbehandlungsanlage gute Planlageergebnisse erzielen. Denn nach wie vor sind eine Vorreckzone und zumindest eine Nachreckzone verwirklicht, wobei die Vorreckung unmittelbar hinter dem Dressiergerüst bis zur nächsten Spannrolle, also bis zur ersten Rolle des Zugreckrollenpaares erfolgt. To achieve this object, the invention teaches a belt treatment plant for straightening metal strips, in particular Stainless steel strips, with a skin pass mill and at least one immediately downstream of the skin pass mill and consisting of at least two idlers Drawstring roller pair, being between the skin pass mill and a pre-stretching zone of the first tensioning roller of the pair of tensioning rollers and between the first and the second idler pulley Drawstring roller pair realized a first post-stretching zone are. The stretching zone can either be for one elastic stretching of the tape up to almost the elastic limit or for a plastic or elastoplastic or be designed semi-elastic stretching. In the streak zone there is a plastic or elastoplastic stretching of the Band. In this respect, the belt tension is on the outlet side of the Skin pass mill so far raised that already between the skin pass mill and the first tension roller of the pair of draw rollers a stretching zone in the form of a stretching zone is realized. On an additional tensioning roller set for Increase the belt tension from the level of the skin pass to the The level of tensile stretching can therefore be completely dispensed with become. This measure reduces the number of tension rollers and not only because of the lower number of idlers reduces the risk of damage to the belt surface, but also be significant Reduced dimensions costs because the number of tensioning pulleys or S-roll is lower than in comparable systems. Surprisingly there is no tensioner set between skin pass mill and draw roller set Loads of achievable flatness. Rather, you can use the flat treatment plant according to the invention has good flatness results achieve. Because still are a stretching zone and realized at least one post-stretching zone, the stretching directly behind the skin pass up to the next tensioning pulley, i.e. up to the first pulley of the Pulling roller pair takes place.

Nach bevorzugter Ausführungsform ist vorgesehen, dass vor dem Dressiergerüst ein erster Spannrollensatz (z. B. ein Bremsrollensatz) und hinter dem Zugreckrollenpaar ein zweiter Spannrollensatz (z. B. ein Zugrollensatz) angeordnet ist. Dabei lässt sich die Planheit weiter optimieren, wenn zwischen dem Zugreckrollenpaar und dem zweiten Spannrollensatz eine zweite Nachreckzone angeordnet ist, welche wie die erste Nachreckzone für eine plastische oder elastoplastische bzw. semiplastische Reckung des Bandes ausgelegt ist. Insofern findet bei dieser Ausführungsform ein sich an das elastische oder elastoplastische Vorrecken anschließendes mehrzoniges elastoplastisches bzw. semiplastisches Nachrecken statt.According to a preferred embodiment, it is provided that a first tensioning roller set (e.g. a Brake roller set) and behind the draw roller pair second tension roller set (e.g. a tension roller set) is. The flatness can be further optimized, if between the pair of draw rollers and the second Tensioning roller set a second stretching zone is arranged, which is like the first stretching zone for a plastic or elastoplastic or semi-elastic stretching of the band is designed. In this respect, this embodiment takes place one of the elastic or elastoplastic stretching subsequent multi-zone elastoplastic or semi-elastic Stretching instead.

Außerdem ist vorgesehen, dass zumindest eine der Spannrollen des Zugreckrollenpaares eine konkave oder konvexe Kontur aufweist. Im Übrigen können auch ein oder mehrere der übrigen Rollen der Bandbehandlungsanlage mit einer konkaven bzw. konvexen Kontur ausgeführt sein. Mit derartigen Spannrollen lässt sich Planheit weiter verbessern. Dieses gilt insbesondere, wenn die Kontur der Spannrollen veränderbar, insbesondere online einstellbar ist. In diesem Zusammenhang ist ferner vorgesehen, dass hinter dem Dressiergerüst ein oder mehrere Planheitsmesseinrichtungen angeordnet sind. So kann z. B. zumindest eine Planheitsmesseinrichtung zwischen dem Dressiergerüst und dem Zugreckrollenpaar angeordnet sein. Es besteht aber auch die Möglichkeit, dass in den weiteren Reckzonen oder auch hinter diesen Reckzonen weitere Planheitsmesseinrichtungen verwirklicht sind. Die mit diesen Planheitsmesseinrichtungen erfassbaren Messergebnisse können online zur Regelung des Reckprozesses verwendet werden, insbesondere wenn man berücksichtigt, dass die Kontur der Spannrollen online einstellbar ist.It is also provided that at least one of the tensioning rollers of the pair of stretching rollers is concave or convex Has contour. In addition, one or more can the remaining roles of the strip treatment plant with one concave or convex contour. With such Tension rollers can be further improved flatness. This is especially true when the contour of the idlers changeable, in particular online adjustable. In this Context is also provided that behind the Skin pass mill one or more flatness measuring devices are arranged. So z. B. at least one flatness measuring device between the skin pass mill and the draw roller pair be arranged. But there is also Possibility that in the other stretching zones or also further flatness measuring devices behind these stretching zones are realized. The one with these flatness measuring devices Measurable results can be recorded online for Regulation of the stretching process can be used, in particular if you take into account that the contour of the idlers is adjustable online.
