Embodiment Construction

[0022] The present invention will be further described below in conjunction with embodiment.

[0023] Specifications: cable copper tape with a thickness of 0.4mm, the processing technology adopts:

[0024] 1. Melting and casting: choose high-purity cathode copper, and make ingredients according to weight ratio. The ingredients ratio refers to: Cu: 99.935-99.945%, 03 / h. (4) Bottom blowing of carbon monoxide to realize deoxygenation of the melt: through the perforated blowing bricks embedded in the refractory layer at the bottom of the smelting furnace and holding furnace, carbon monoxide is blown in, and the molten copper is blown to make the ingot Oxygen content drops significantly, and the amount of carbon monoxide injected into each furnace is 1.3Nm 3 .

[0025] 2. Ingot heating: The ingot is heated by a walking heating furnace, which requires good heating uniformity of the ingot. The temperature in the heating zone is 930°C, the temperature in the holding zone is 960°C, ...

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...
