Abstract
Description
"Walze" Die Erfindung betrifft eine Walze fqr das Auswalzen von Kupfer und Kupferlegierungen. "Roller" The invention relates to a roller for rolling out copper and copper alloys.
Bisher verwendet man zum Auswalzen von Kupfer Walzen aus geschmiedetem legiertem Stahl. Diese Walzen verschleißen rasch, insbesondere wenn sie gerillt bzw. kalibriert sind und zum kontinuierlichen Warmwalzen verwendet werden. Der rasche Verschleiß dieser Walzen wird durch Korrosion bewirkt, die wiederum die Folge der in die Walzemulsion eingetauchten galvanischen Paarung Nupfer/Stahl (der Walze) ist. Diese Korrosion bewirkt Risse, die sich beim Walzvorgang durch Eindringen mit Kupfer füllen, bis Stahlstücke abblättern und sogar ein Abblättern von Stahlstücken.So far, forged copper rolls have been used for rolling out copper alloy steel. These rolls wear out quickly, especially if they are grooved or are calibrated and used for continuous hot rolling. The quick one Wear of these rollers is caused by corrosion, which in turn is the result of galvanic pairing of Nupfer / steel (of the roller) immersed in the roller emulsion is. This corrosion causes cracks that appear during the rolling process through penetration with copper fill until pieces of steel are peeling off and even pieces of steel are peeling off.
Bei Walzen gemäß der Erfindung sind diese Nachteile der bekannten Stahlwalzen vermieden. Die Walze nach der Erfindung besitzt einen Stahlkern sowie einen Mantel aus einem, Material, welches der Korrosion bei der Berührung mit dem auszuwalzenden Metall in der Walzemulsion widersteht.In the case of rollers according to the invention, these disadvantages are known Steel rollers avoided. The roller according to the invention has a steel core as well a jacket made of a material that is resistant to corrosion when it comes into contact with the Resists to be rolled metal in the rolling emulsion.
Der Mantel hat vorzugsweise die Form eines Ringes. Dieser Ring wird mit Rillen oder Kalibern auf der Außenseite versehen, wenn ein anderes Profil als ein Blech gewalzt werden soll Der Ring kann am Kern durch einfaches Kleben befestigt sein, beispielsweise mit Hilfe des im Handel unter der Bezeichnung Haraldite" bekannten Klebstoffes.The jacket is preferably in the form of a ring. This ring will provided with grooves or calibres on the outside if a different profile than a sheet is to be rolled The ring can be attached to the core by simply gluing be, for example with the help of the commercially known under the name Haraldite " Adhesive.
Der Ring kann gleichermaßen hart auf den Kern aufgelötet werden, nachdem er auf der Innenseite metallisiert wurde.The ring can be soldered to the core equally hard after it was metallized on the inside.
-Als Material für den Mantel eignen sich insbesondere gesinterte ,warmgepreßte oder elektrogeschmolzene Keramikmaterialien, wie sie bereits als Werkstoffe für die Herstellung von Schneidwerkzeugen bekannt sind.- Sintered, hot-pressed ones are particularly suitable as the material for the jacket or electro-fused ceramic materials, as they are already used as materials for the manufacture of cutting tools are known.
Derartige Materialien snd ffi Zr°2; Ak03; A1203-MgO (bis zu 0,5 % MgO); A1203 mit mindestens 10 % TiO; Al20$ mffi mindestens 10 % TiN; A1203 mit einem Gehalt an MgO-TiC-Cr; A1203 mit einem Gehalt an Cr3C2; A1203 mit einem Gehalt an Cr203; A1203 mit einem Gehalt an NiO-MgO; Keramikmaterialien auf der Basis von Carbiden, Boriden, Nitriden und Oxyden von Si, Zr, Ta, Ti, W, Mo oder B.Such materials are ffi Zr ° 2; Ak03; A1203-MgO (up to 0.5 % MgO); A1203 with at least 10% TiO; Al20 $ mffi at least 10% TiN; A1203 with a content of MgO-TiC-Cr; A1203 containing Cr3C2; A1203 with a salary at Cr203; A1203 containing NiO-MgO; Ceramic materials based on Carbides, borides, nitrides and oxides of Si, Zr, Ta, Ti, W, Mo or B.
Ein Zylinder gemäß der Erfindung mit einem Mantel aus elektrogeschmolzenem Aluminiumoxyd, welcher mit Rillen oder Kalibern versehen war, zeigte nach 50 stündigem Warmwalzen von Kupferdraht nicht das geringste Zeichen von Verschleiß oder einer;<erBdung mit Kupfer. Demgegenüber mußte unter den gleichen Arbeitsbedingungen das Kaliber einer konventionellen Walze aus geschmiedetem legiertem Stahl wegen des Verschleisses alle 10 Stunden ersetzt werden.A cylinder according to the invention with a jacket made of electrofused Aluminum oxide, which was provided with grooves or calibers, showed after 50 hours Hot rolling of copper wire did not show the slightest sign of wear or grounding with copper. In contrast, the caliber a conventional roller made of forged alloy steel due to wear replaced every 10 hours.
Die Zeichnung zeigt einen Axialschnitt durch eine Walze gemäß der Erfindung. Bei dieser ist ein Ring 1 aus korrosionsbeständigem hartem Material mit einer Rille oder einem Kaliber 2 versehen und mittels eines Klebstoffes 3 auf einen hohlen Stahlkern 4 aufgeklebt.The drawing shows an axial section through a roller according to FIG Invention. This is a ring 1 made of corrosion-resistant hard material with a groove or a caliber 2 provided and by means of an adhesive 3 on a hollow steel core 4 glued on.
