Ultralong high-conductivity cable copper tape and production technology thereof

Abstract

The invention discloses an ultralong high-conductivity cable copper tape and a production technology thereof. The copper tape comprises the following components by weight percentage: 99.935-99.945% of Cu, P greater than 0 and less than or equal to 0.001%, O greater than 0 and less than or equal to 0.001%, Ce greater than 0 and less than or equal to 0.06%, and impurities less than 0.055%. The production technology of the copper tape comprises the steps of casting, heating, hot rolling, face milling, rough rolling, edge trimming, cleaning, finish rolling, finished product annealing, finished product shearing, packing and warehousing. The production technology is short in production cycle; processing is easy; the conductivity of the produced copper tape reaches above 100% IACS (International Annealed Copper Standard); and the length of the finished copper tape can reach above 8000m. The production technology comprehensively adopts four deoxidation techniques (including rare earth element Ce addition), so that the oxygen content of the copper tape is controlled below 10ppm.

Description

technical field [0001] The invention belongs to the field of nonferrous metal processing, and in particular relates to an ultra-long high-conductivity cable copper strip and a production process thereof. Background technique [0002] At present, the problems in the production of copper tape for cables are low conductivity, poor ductility, high production cost, and it is difficult to form continuous mass production. Contents of the invention [0003] The purpose of the present invention is to provide a super-long high-conductivity cable copper strip with high conductivity and high ductility, and a short-flow production process that can effectively reduce costs. [0004] An ultra-long high-conductivity cable copper tape, its weight ratio components are: Cu: 99.935-99.945%, 0<P≤0.001%, 0<0≤0.001%, 0<Ce≤0.06%, and the sum of impurities<0.055% . [0005] Preferably, said 0<Ce≤0.04%. [0006] Preferably, the Ce is 0.04%. [0007] The present invention also pro...
