Abstract

The invention discloses a method for manufacturing a high-conductivity corrosion-resistant pure copper special cable, and belongs to the technical field of material processing. High-purity cathode electrolytic copper is adopted as a substrate of a wire, and the cable is formed through mixing and preheating, smelting, heat preservation, traction, wire drawing, crystallization, annealing and cooling and oxide layer plating treatment. The TR specification volume resistivity of the cable is smaller than or equal to 0.01707omega.cm<3>, and the tensile strength of the cable is more than 420 MPa. The method can meet the requirement of submarine cables for high-conductivity corrosion-resistant materials well, and can be used for the field requiring high-conductivity high-strength materials. The method has the advantages of being simple in process and low in cost.

Description

technical field [0001] The invention belongs to the technical field of material processing, and more specifically relates to a preparation method of a special cable made of high-conductivity and corrosion-resistant pure copper. Background technique [0002] Pure copper has high electrical and thermal conductivity, high plastic deformation ability, and good corrosion resistance. It is widely used in industry as a good conductor. However, although pure copper has the advantage of high electrical conductivity, its tensile strength is extremely low, usually only 120-160MPa. In addition, pure copper has high plastic deformation ability, but it is easy to work harden due to its extremely low static recrystallization temperature, thereby inhibiting further plastic deformation. Therefore, pure copper materials are mostly used in wires, conductors and coolers, etc., and it is difficult to meet various application requirements as a structural material. Generally, the conductivity o...
