Abstract

Ein Haspeltreiber für Walzwerke mit einer oberen und einer unteren Treiberrolle soll so weitergebildet werden, dass das Walzgut von den Rollen nicht beschädigt wird, dass das Walzgut nicht an den Rollen kleben bleibt und dass die Treiberrollen als klassische Verschleißteile kostengünstig zu erstellen sind. Dazu wird vorgeschlagen, dass die untere Treiberrolle eine Rollenachse aus Stahl aufweist, auf die ein Gussmantel aufgeklebt und/oder aufgeschrumpft ist, und/oder dass die obere Treiberrolle einen Gussmantel aufweist, der zwischen zwei auf einer Achse angeordneten Klemmelementen gehalten ist.A reel driver for rolling mills with an upper and a lower drive roller is to be developed so that the rolling stock is not damaged by the rollers, that the rolling stock does not stick to the rollers and that the driver rollers are to create cheap as a classic wearing parts. For this purpose, it is proposed that the lower drive roller has a roller axle made of steel, to which a casting shell is glued and / or shrunk on, and / or that the upper drive roller has a casting shell, which is held between two clamping elements arranged on an axis.

Description

Die Erfindung betrifft einen Haspeltreiber für Walzwerke mit einer oberen und einer unteren Treiberrolle.The The invention relates to a reel driver for rolling mills with an upper and a lower driver role.

Derartige Haspeltreiber werden in Warm- sowie in Kaltwalzwerken eingesetzt. Die untere Treiberrolle besteht aus Vollmaterial, z. B. Stahl mit einer auftragsgeschweißten Verschleißschicht, während die obere Treiberrolle als Hohlrolle aus Stahl mit auftragsgeschweißter Verschleißschicht ausgebildet ist.such Reel drivers are used in hot and cold rolling mills. The lower driver roller is made of solid material, for. B. steel with an order-welded Wearing course, while the Upper driver roller as a hollow steel roller with an application-welded wear layer is trained.

Als nachteilig hat sich jedoch erwiesen, dass die Rollen Poren auf der Oberfläche des Rollenmantels aufweisen, welche in dem Walzgut zu Abdrücken führen können, dass die Verschleißschicht der Rollen nur einen kleinen Nutzbereich haben, dass das Walzband an den Rollen oft haften bleibt, und dass die auftragsgeschweißten Rollenkörper nur sehr kostenintensiv zu erstellen sind.When However, it has proved disadvantageous that the rollers have pores on the rollers surface of the roll mantle, which can lead to imprints in the rolling stock, that the wear layer the rollers have only a small working area, that the rolled strip often sticks to the rollers, and that the job-welded reel body only are very expensive to create.

Der Erfindung liegt die Aufgabe zugrunde, einen Haspeltreiber bereit zu stellen, der diese Nachteile vermeidet.Of the Invention is based on the object, a reel driver ready to make that avoids these disadvantages.

Diese Aufgabe wird dadurch gelöst, dass die untere Treiberrolle eine Rollenachse aus Stahl aufweist, auf die ein Gussmantel aufgeklebt und/oder aufgeschrumpft ist.These Task is solved by that the lower driver roller has a steel roller axle, on which a cast coat is glued and / or shrunk.

Die Aufgabe wird aber auch dadurch gelöst, dass die obere Treiberrolle einen Gussmantel aufweist, der zwischen zwei auf einer Achse angeordneten Klemmelementen gehalten ist.The Task is also solved by the fact that the upper driver role a casting shell arranged between two on an axis Clamping elements is held.

Durch die Verwendung von Gussmänteln wird erreicht, dass die Rollen an ihren mit dem Walzgut in Kontakt kommenden Oberflächen keine Poren aufweisen, so dass die Walzgutoberfläche beim Kontakt mit den Treiberrollen keine Beschädigung erfährt. Hinzu kommt, dass das Band weniger dazu neigt, am Rollenmantel haften bzw. kleben zu bleiben Von Vorteil ist dabei, dass der Gussmantel außen eine Arbeitsschicht aufweist. Diese Arbeitsschicht kann kostengünstig ausreichend dick im Schleudergussverfahren hergestellt werden, so dass die Rollen einen größeren Abschliffbereich und eine größere Lebensdauer besitzen.By the use of cast covers becomes ensures that the rollers at their coming into contact with the rolling stock surfaces have no pores, so that the Walzgutoberfläche in contact with the driver rollers no damage experiences. In addition, the tape is less prone to adhere to the roll shell The advantage is that the cast shell outside one Working layer has. This working shift can be inexpensive enough be made thick by centrifugal casting, so that the rollers a larger grinding area and a longer life have.

Wird der Gussmantel aus Sphäroguss und die Arbeitsschicht aus Indefiniteguss hergestellt, so ergibt sich ein kostengünstiger Mantel, der durch den Indefiniteguss eine große Härte aufweist, und der damit eine erheblich größere Lebensdauer erreicht.Becomes the cast shell made of ductile iron and the working layer made of indefinite cast, so gives a cost-effective Cloak, which has a high hardness due to the indefinite cast, and with it a much longer life reached.

Wird die Arbeitsschicht aus Chromguss oder sogar aus Schnellstahl hergestellt, so ergeben sich gegenüber Indefiniteguss noch größere Härten und längere Lebensdauern.Becomes the working layer made of cast chrome or even made of high-speed steel, so arise opposite Indefiniteguss even greater hardness and longer lifetimes.

Die Erfindung wird anhand einer Zeichnung näher erläutert. Dabei zeigtThe The invention will be explained in more detail with reference to a drawing. It shows

1 den Querschnitt durch eine untere Treiberrolle und 1 the cross section through a lower driver roller and

2 den Querschnitt durch eine obere Treiberrolle. 2 the cross section through an upper driver role.

Der 1 ist eine untere Treiberrolle 1 zu entnehmen, die eine Rollenachse 2 aus Stahl aufweist, auf die ein Gussmantel 3 aufgeklebt und/oder aufgeschrumpft ist. Der Gussmantel 3 wird im Schleudergussverfahren hergestellt. Er weist am Außenumfang eine verschleißbeständige Arbeitsschicht 4 auf.Of the 1 is a lower driver role 1 to take the one roller axis 2 made of steel, on which a cast-iron jacket 3 glued and / or shrunk. The cast coat 3 is produced by centrifugal casting. He has on the outer circumference a wear-resistant working layer 4 on.

Die 2 zeigt eine obere Treiberrolle 1' mit einer Rollenachse 2'. Auf der Rollenachse 2' ist ein Gussmantel 3' durch zwei Klemm-Elemente 5 geklemmt. Die äußere Schicht des Gussmantels 3' wird von einer im Schleudergussverfahren hergestellten verschleißbeständigen Arbeitsschicht 4' gebildet.The 2 shows an upper driver role 1' with a roller axle 2 ' , On the roll axis 2 ' is a cast coat 3 ' by two clamping elements 5 clamped. The outer layer of the cast envelope 3 ' is made of a centrifugally cast wear-resistant working layer 4 ' educated.
