Aluminum foil for electric cable and production method

Abstract

The invention discloses a cable aluminum foil and a production method thereof. The cable aluminum foil comprises components of the following weight percent: 0.79 to 0.83 percent of Si, 0.22 to 0.26 percent of Fe, at most 0.1 percent of Cu, at most 0.2 percent of Mn, at most 0.05 percent of Mg, at most 0.05 percent of Cr, at most 0.1 percent of Zn, at most 0.08 percent of Ti, at most 0.05 percent of single impurity content, at most 0.15 percent of the total content of impurities and Al as the rest, wherein the content summation of the Fe and the Si in weight percent is less than 1.1 percent. The production method comprises the production technical processes: burdening, melting, component analysis, feeding dilution, powder injection refining, N2 refining, on-line refining outside a furnace, casting, casting plate type detection, blank winding, cold rolling, vertical cutting and splitting, finished product annealing, detection, packing, storage and leaving a factory. The cable aluminum foil has good mechanical property, the tensile strength is from 90 to 105MPa, the extension rate is greater than 25 percent, the production requirement has larger development potential, and the enterprise benefit and the social benefit can be obviously increased.

Description

Technical field: [0001] The invention relates to an alloy material of aluminum foil for cables and a production method thereof, which are used as basic materials for communication cables, optical fiber cables and other industries. Background technique: [0002] Cable aluminum foil tape is one of the main basic materials for the production of communication cables and optical fiber cables. After aluminum-plastic composite, it covers the cable core to play the role of shielding, moisture-proof and increasing strength. Ordinary products require an aluminum foil thickness of about 0.15mm, a width of 500-800mm, and a length of more than 2Km. The product alloy is often made of aluminum alloy, with a tensile strength of 60-85Mpa and an elongation of 15-17% (the standard specification is : 50mm calibration distance) the thickness tolerance of the aluminum foil is plus or minus 8 to 15 microns. [0003] With the rapid development of the national economy, the domestic demand for alumi...
