Description

Kaltwalzen mit Bohrungsschutz Kaltwalzen, vornehmlich zur Erzeugung feiner Metallbänder, sind üblicherweise mit einer Bohrung versehen, um die beim Walzen entstandene Wärme durch eine Flüssigkeitskühlung wieder abführen zu können. Als Kühlflüssigkeit wird hauptsächlich Wasser verwendet. Es ist bereits vorgeschlagen worden, in die Bohrung von Kaltwalzen Kupferrohre einzuwalzen. Es kommt aber häufig vor, daß sich die Einwalzstelle an der Stirnseite löst, so. daß Wasser zwischen Bohrungswandung und der Walze und Kupferrohr eindringen und so an unkontrollierbarer Stelle die Walze gefährden kann.Cold rolling with hole protection Cold rolling, primarily for production fine metal strips are usually provided with a hole in order to prevent the Rollers to be able to dissipate heat generated by a liquid cooling. The main coolant used is water. It's already suggested been used to roll copper pipes into the bores of cold rolling. But it happens often before that the rolled-in point loosens on the front side, so. that water between Bore wall and the roller and copper pipe penetrate and so at uncontrollable Position can endanger the roller.

Ferner tritt häufig durch die dynamische Beanspruchung ein stellenweises Ablösen des Kupferrohres von der Bohrungswandung auf, wodurch ,die erforderliche Kühlwirkung vermindert wird. Darüber hinaus ist das Einwalzen eines Kupferrohres ein verhältnismäßig kostspieliger Vorgang. Gegenstand der Erfindung sind Kaltwalzen mit erhöhter Haltbarkeit, bei denen die Wandung der Bohrung mit einer festhaftenden Gummischicht überzogen ist. Es empfiehlt sich, zur Vermeidung von Wärmestau die Gummischicht möglichst dünn zu halten.Furthermore, the dynamic stress often causes a spot Detachment of the copper pipe from the bore wall, whereby the required Cooling effect is reduced. In addition, there is the rolling in of a copper pipe a relatively expensive process. The invention relates to cold rolling with increased durability, in which the wall of the bore with a firmly adhering Rubber layer is coated. It is advisable to use the Keep the rubber layer as thin as possible.
