Abstract
Description
In der Papier- und/oder Zellstoffindustrie werden sogenannte Refiner eingesetzt, mit deren Hilfe beispielweise Holzstoff und/oder Zellstoffe sowie Hadern- und Recyling stoff gemahlen werden können. Zu diesem Zweck benötigen die Refiner ein Werkzeug, nämlich ein Mahlwerkzeug, welches je nach Ausgestaltung des Refiners, beispielsweise als Kegelrefiner oder Scheibenrefiner als Kegel oder Scheibe oder Segment ausgebildet ist. Diese Elemente unterliegen einem sehr hohen Verschleiß. Seit jeher wird deshalb versucht, die Standfestigkeit derartiger Werkzeuge zu erhöhen. Aus diesem Grund hat man der Werkstoffauswahl bisher große Aufmerksamkeit geschenkt und deshalb derartige Werkzeuge, beispielsweise aus säurefesten Stählen und/oder Gußmaterialien hergestellt. Werkzeuge aus Stahl werden beispielsweise zumindest an der beanspruchten Oberfläche gehärtet.So-called refiners are used in the paper and / or pulp industry their help for example wood pulp and / or cellulose as well as rag and recycling can be ground. For this purpose, the refiners need a tool namely a grinding tool which, depending on the design of the refiner, for example designed as a cone refiner or disc refiner as a cone or disc or segment is. These elements are subject to very high wear. That is why it has always been tries to increase the stability of such tools. For this reason So far, great attention has been paid to the choice of materials and therefore such tools, for example made of acid-proof steels and / or cast materials manufactured. Steel tools are used, for example, at least on the claimed Hardened surface.
Der Erfindung liegt die Aufgabe zugrunde, Mahlwerkzeug sowie ein Verfahren zu schaffen bzw. vorzuschlagen, durch welche mit einer gezielten Behandlung das Werkzeug des Refiners mit langandauernder Wirkung standfest gemacht werden kann.The invention is based, grinding tool and a method to the task create or propose through which with a targeted treatment the The refiner's tool can be made stable with a long-lasting effect.
Diese Aufgabe wird bei einem Refiner erfindungsgemäß dadurch gelöst, daß zunächst in die Oberfläche der Wirkfläche des Werkzeuges mittels eines plasmagestützten Verfahrens Fremdionen mit einer Eindringtiefe von bis zu 500 µm eingelagert sowie eine zusätzliche Hartstoffschicht an der Oberfläche angelagert wird. Die Fremdionenanlage rung erfolgt durch beschleunigte Ionen mit definierter Energie. Die zu implantierenden Fremdionen werden in einem reaktionsfähigen Plasma in die Werkstoffoberfläche eingeschossen. Die Anzahl der implantierten Fremdionen und deren Eindringtiefe ist dabei durch entsprechende Konzentrationen der Fremdionen variabel, d. h. die Anzahl der implantierten Fremdionen und deren Eindringtiefe ist exakt festlegbar und abhängig von den verwendeten Materialien und der Energie der Fremdionen. Eine derartige Vorgehensweise hat insofern Vorteile, als nur wenige Parameter im Prozess zu beachten sind, nämlich die Fremdionendosis, die Teilchenenergie und die Beschußzeit. Der Prozess ist somit sehr gut kontrollierbar und das Ergebnis ohne weiteres reproduzierbar. Zusätzlich wird eine Hartstoffschicht angelagert, wodurch sich der zusätzliche Vorteil ergibt, daß die Oberflächenstruktur verdichtet wird.This object is achieved in a refiner according to the invention in that first in the surface of the active surface of the tool by means of a plasma-assisted Process foreign ions with a penetration depth of up to 500 µm and a additional hard material layer is deposited on the surface. The foreign ion system tion takes place through accelerated ions with defined energy. The ones to be implanted Foreign ions are released into the material surface in a reactive plasma injected. The number of foreign ions implanted and their penetration depth is variable by appropriate concentrations of foreign ions, d. H. the number the implanted foreign ions and their penetration depth can be precisely determined and dependent of the materials used and the energy of the foreign ions. Such The procedure has advantages in that only a few parameters have to be considered in the process are, namely the foreign ion dose, the particle energy and the bombardment time. The The process is therefore very easy to control and the result is easily reproducible. In addition, a hard material layer is deposited, which has the additional advantage shows that the surface structure is compressed.
Vorteilhafte Ausgestaltungsmerkmale der Erfindung sind in den Unteransprüchen enthalten, insbesondere hinsichtlich der Zusammensetzung der Fremdionen einerseits sowie der Hartstoffschicht andererseits.Advantageous design features of the invention are in the subclaims contain, in particular with regard to the composition of the foreign ions on the one hand and the hard material layer on the other.
Von besonderer Bedeutung für die vorliegende Erfindung ist die verfahrensmäßige Vorgehensweise, wonach das Einlagern von Fremdionen in die Oberfläche des Werkzeuges sowie das Einlagern einer Hartstoffschicht an die Oberfläche in einem Arbeitsgang erfolgt.The procedural aspect is of particular importance for the present invention Procedure according to which the storage of foreign ions in the surface of the Tool and the incorporation of a hard material layer on the surface in one Operation is carried out.
Als Werkzeug im Sinne der vorliegenden Erfindung kommen sowohl Kegel bei einem Kegelrefiner oder Scheiben bzw. Segmente bei einem Scheibenrefiner oder Doppelschei benrefiner in Frage.As a tool in the sense of the present invention, both cones come in one Cone refiner or discs or segments with a disc refiner or double disc benrefiner in question.
