Description

Die Erfindung betrifft Walzen eines Walzwerkes zum Herstellen von ein- oder mehrschichtigem Walzgut aus Metallpulver, insbesondere Eisenpulver, bei dem die Achsen der Walzen in einer waagerechten oder schwach geneigten Ebene liegen, ihr Durchmesser ein Vielfaches der Dicke des Walzgutes beträgt und die Walzenoberfläche leicht aufgerauht ist.The invention relates to rolls of a rolling mill for the production of single or multi-layer Rolled material made of metal powder, in particular iron powder, in which the axes of the rollers in a horizontal or slightly inclined plane, their diameter is a multiple of the thickness of the rolled material and the roller surface is slightly roughened.

Die Ausbildung der Walzen gemäß der Erfindung ίο besteht darin, daß die Aufrauhung der Oberfläche durch flache Rillen bewirkt ist, die in Achsrichtung verlaufen. Durch diese Rillen wird eine gute Durchknetung oder Verfilzung des Metallpulvers herbeigeführt und damit die Festigkeit des Walzgutes erhöht. The formation of the rollers according to the invention consists in the roughening of the surface is caused by shallow grooves that run in the axial direction. These grooves ensure good kneading or felting of the metal powder and thus increasing the strength of the rolling stock.

In der Zeichnung ist eine Ausführungsform von Walzen gemäß der Erfindung schematisch dargestellt. In the drawing is an embodiment of Rolls according to the invention shown schematically.

Die beiden mit waagerechten Achsen angeordneten Walzen 1 und 2, zwischen denen der Eisenpulvervorratsbehälter 3 liegt, weisen auf ihrer Oberfläche Längsrillen 4 auf. Durch diese Rillen wird eine bessere Mitnahme des Eisenpulvers hervorgerufen, die eine günstige Verpressung und ein gutes Zusammenhatten des aus dem Walzwerk austretenden Bandes ergibt.The two rollers 1 and 2 arranged with horizontal axes, between which the iron powder storage container 3, have longitudinal grooves 4 on their surface. Through these grooves will a better entrainment of the iron powder caused a favorable compression and a good cohesion of the strip emerging from the rolling mill results.

Die Tiefe der Rillen kann verschieden sein und gegebenenfalls auch dem Metallpulver angepaßt werden; sie wird im allgemeinen Bruchteile von Millimetern nicht übersteigen.The depth of the grooves can be different and, if necessary, also adapted to the metal powder will; it will generally not exceed fractions of a millimeter.
