Abstract

The present invention relates to the novel processing technology of a kind of high argentiferous copper cash, comprise the following steps: cathode copper is joined and draws the power frequency induction furnace of power frequency continuous casting unit and carry out melting by (1), and it is added thereto to the Ag of 1.5% 4.5% weight ratios, smelting temperature is 1,180 1200 DEG C, being gone out to cast bar by its conticaster direct casting again, casting bar cools down in a device；(2) casting bar is sent in extruder continuously extruded, the diameter being less than casting bar by diameter of extruder, make the diameter extruding of casting bar diminish, make casting bar secondary crystallization, crystal grain refines, and improves its intensity；(3) use special-shaped mould cold drawing technology, the casting bar after extruding is passed sequentially through the cold drawn mould that diameter tapers into so that the diameter of casting bar tapers into, by obtaining the argentiferous copper cash of design size after the continuous drawings of 20 30 times；In casting bar drawing process, casting bar is made annealing treatment at least one times, eliminates residual stress, stable dimensions.

Description

A kind of processing technique of high argentiferous copper cash
Technical field
The present invention relates to the manufacture field of wire rope, be specifically related to the novel processing technology of a kind of high argentiferous copper cash.
Background technology
In recent years, along with data such as the development of scientific and technological progress, Aero-Space, communication, high end audio audio signals What transmission field application lead technology required improves constantly, and the material composition of its data wire and processing technique are also the most progressive. Traditional cable uses traditional copper cash silver plating process, its complex process, and production efficiency is low.
Summary of the invention
It is an object of the invention to provide the novel processing technology of a kind of high argentiferous copper cash.
The technical scheme that the present invention takes is:
The processing technique of a kind of high argentiferous copper cash, comprises the following steps:
(1). cathode copper is joined and draws the power frequency induction furnace of power frequency continuous casting unit and carry out melting, and be added thereto to 1.5%- The Ag of 4.5% weight ratio, smelting temperature is 1180-1200 DEG C, then is gone out to cast bar by its conticaster direct casting, and casting bar is in a device Cooling；
(2). casting bar is sent in extruder continuously extruded, the diameter being less than casting bar by diameter of extruder, make the straight of casting bar Footpath extruding diminishes, and makes casting bar secondary crystallization, and crystal grain refines, and improves its intensity；
(3). use special-shaped mould cold drawing technology, the casting bar after extruding is passed sequentially through the cold drawn mould that diameter tapers into, makes The diameter that must cast bar tapers into, by obtaining the argentiferous copper cash of design size after the continuous drawing of 20-30 time；In casting bar drawing During, casting bar is made annealing treatment at least one times, eliminates residual stress, stable dimensions.
After taking above technical scheme, the invention have the benefit that drawing extrusion process in employing substitutes traditional copper cash Silver plating process, is directly added into the silver element high silver-bearing copper pole of production in upper drawing, eliminates the silver-plated operation of follow-up copper cash in fusion-casting process, Material property uniform and stable can not only be effectively ensured, meet the requirement of data signal transmission high-resolution, significantly carry simultaneously High production efficiency, reduces production cost.Yellow gold casting bar is carried out the continuously extruded of a time so that it is secondary crystallization, Crystal grain refines, and improves its intensity.The drawing again it being carried out multi-pass and annealing so that it is dimensions and performance indications are stable.
Detailed description of the invention
Hereinafter the detailed description of the invention of the present invention is further described:
The processing technique of a kind of high argentiferous copper cash, comprises the following steps:
(1). cathode copper is joined and draws the power frequency induction furnace of power frequency continuous casting unit and carry out melting, and be added thereto to 1.5%- The Ag of 4.5% weight ratio, smelting temperature is 1180-1200 DEG C, then is gone out the casting of a diameter of about 25mm by its conticaster direct casting Bar, casting bar cools down in a device；
(2). sending in extruder continuously extruded by casting bar, a diameter of about the 20mm of extrusion of extruder casts bar, and extrusion process makes Must cast bar secondary crystallization, crystal grain refines, and improves its intensity；
(3). use special-shaped mould cold drawing technology, the casting bar after extruding is passed sequentially through the cold drawn mould that diameter tapers into, makes The diameter that must cast bar tapers into, by finally give after the continuous drawing of 20-30 time a diameter of 0.10mm argentiferous copper cash； In casting bar repeatedly drawing process, casting bar is made annealing treatment at least one times, eliminates residual stress, stable dimensions.
After tested, the ambient temperature mechanical properties of this kind high argentiferous copper cash using this technique to produce is: tensile strength Rm >= 450MPa, elongation percentage A200 >=12%, conductivity >=88%IACS.

Claims (1)

1. the processing technique of one kind high argentiferous copper cash, it is characterised in that comprise the following steps:
(1) cathode copper is joined draw the power frequency induction furnace of power frequency continuous casting unit and carry out melting, and be added thereto to 1.5%- The Ag of 4.5% weight ratio, smelting temperature is 1180-1200 DEG C, then is gone out to cast bar by its conticaster direct casting, and casting bar is in a device Cooling；
(2) casting bar is sent in extruder continuously extruded, the diameter being less than casting bar by diameter of extruder, make the diameter of casting bar Extruding diminishes, and makes casting bar secondary crystallization, and crystal grain refines, and improves its intensity；
(3) use special-shaped mould cold drawing technology, the casting bar after extruding passed sequentially through the cold drawn mould that diameter tapers into so that The diameter of casting bar tapers into, by obtaining the argentiferous copper cash of design size after the continuous drawing of 20-30 time；In casting bar drawing Cheng Zhong, makes annealing treatment at least one times casting bar, eliminates residual stress, stable dimensions.
