Description

Die Erfindung betrifft einen Haspeltreiber für Walzwerke nach dem Oberbegriff des Patentanspruches 1 sowie nach dem Oberbegriff des Patentanspruches 2.The The invention relates to a reel driver for rolling mills according to the preamble of claim 1 and according to the preamble of claim Second

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 aus Stahl mit auftragsgeschweißter Verschleißschicht ausgebildet ist.such Reel drivers are used in hot and cold rolling mills. The lower driver roll is made of solid material, z. B. steel with an order-welded Wearing course, while the Upper driver roller made of steel 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 der eingangs genannten Art bereit zu stellen, der diese Nachteile vermeidet.Of the Invention is based on the object, a reel driver of the beginning to provide said type, which avoids these disadvantages.

Die JP 57115915 A offenbart eine Verbundwalze, bei der eine Schicht der Verbundwalze aus einem derartig kostenintensiv zu erstellenden auftragsgeschweißten Material und die zweite, dünne Schicht im Schleudergießverfahren hergestellt werden.The JP 57115915 A discloses a composite roll in which a layer of the composite roll is made from an electrodeposited weld material and the second, thin layer is spin cast.

Die EP 0 747 147 A2 offenbart eine obere als Hohlrolle ausgebildete Treiberrolle, die zwischen zwei auf einer Achse angeordneten Klemmelementen gehalten ist. Über die Oberfläche der Rolle sind keine Angaben gemacht.The EP 0 747 147 A2 discloses an upper drive roller formed as a hollow roller, which is held between two arranged on an axis clamping elements. No information is given about the surface of the roll.

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.The Task is also solved by the fact that the upper driver role having a cast shell.

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 bleibenBy 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 or stick to stick

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.From The advantage here is that the casting shell outside has a working layer. This working layer can cost sufficiently thick in the centrifugal casting process be prepared so that the rollers have a larger Abschliffbereich 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.
