Abstract

Der Kupferdraht weist einen mittleren Kupfergehalt von mindestens 99,95 Gewichtsprozenten sowie mindestens einen dem Kupfer zulegierten Begleiter auf. Ein Quotient aus dem Gewichtsanteil des Begleiters und einem Gewichtsanteil eines Restsauerstoffgehaltes weist einen Wert im Intervall von 0,8 bis 1,7 auf. Der Gewichtsanteil des Begleiters variiert entlang einer Drahtlänge um maximal 25 % bezogen auf den maximalen Gewichtsanteil des Begleiters. Verfahrenstechnisch wird der Kupferdraht durch einen Gießvorgang mit anschließender Weiterverarbeitung hergestellt. Die Kupferschmelze wird bis zu einer Erstarrung gegenüber einer Umgebungsatmosphäre geschützt. Zur Gewährleistung einer genauen Zulegierung des Begleiters weist die Vorrichtung zur Herstellung des Kupferdrahtes eine Dosierregelung mit angeschlossener Dosiereinrichtung auf.The copper wire has a mean copper content of at least 99.95% by weight and at least one Copper alloyed companion on. A quotient of the weight fraction of the companion and a weight fraction of one Residual oxygen content has a value in the interval of 0.8 to 1.7 on. The weight percentage of the companion varies along a wire length by a maximum of 25% relative to the maximum weight of the companion. process engineering is the copper wire by a casting process with subsequent Further processing produced. The copper melt is up to a solidification to an ambient atmosphere protected. To ensure an accurate Admission of the companion has the device for production of the copper wire a dosing with connected Dosing on.
