Description
Technical field
The invention belongs to copper covered steel technical field is and in particular to a kind of multi-layer classification high strength type welding wire wire rod.
Background technology
Copper covered steel as its name suggests, is that copper-clad steel wire, that is, the composite wire of steel wire periphery parcel layers of copper, it utilizes low
The Kelvin effect of pressure high-frequency signal, walks along surface in high frequency region, as long as so copper layer thickness reaches certain limit, certain frequency
The signal of section just can be ensured that transmission.Copper plays the effect of conduction weak electric signal, and steel wire is then played a supporting role.
Wrap up in the distinct methods of steel wire according to copper-clad, be broadly divided into plating, cladding, hot-cast/leaching and electroforming.Existing market
On copper covered steel substantially use electroplating technology, that is, use the electroplating technology of electrolytic cell operation principle by block copper coin " dissolving "
Then it is directed to covering on steel wire through electric current.Cladding is by copper strips wrapped wire, welds in the seam argon arc welding of parcel；
Hot-cast/leaching is that copper heating is molten into liquid, and steel wire passes through rear band copper liquid and then cooled and solidified；Electroforming is that the special of plating should
With the reduction realizing copper in former is assembled, and such technique is still rare.
Purpose according to application is different, and copper covered steel mainly can be categorized as：1. the center conductor of communication cable；2. communicate electricity
The shielding braid line of cable；3. the lead-foot-line of electronic devices and components；4. the earth lead of twisted wire shape and electric railway circuit；5. other dresses
Decorations or the line of anticorrosion purposes.
On the basis of copper covered steel, still can carry out different classes of deep processing, including tin plating, silver-plated, japanning, and bundle
Silk, stranding, system nail, or bright annealing braiding etc..
Copper covered steel wire abbreviation CCS line, is with high-quality low-carbon (LC) steel for base core, the NEW TYPE OF COMPOSITE material processing through copper facing
Material.The intensity of existing steel and toughness have electric conductivity, solderability and a rotproofness of copper again, good high frequency, have light specific gravity,
Section copper material, cost are low, are the replacement new products of traditional copper wire.It is widely used in the electric conductor of communication electric wire cable, be mainly used in
Telephone wire, draw down silk etc..
The structure of existing welding wire is single, low intensity, and tensile property is poor, and it is frequently drawn in installation process
Pull flexible it is easy to disconnected by pullling, simultaneously during using, the unexpected release of the stress gathering when mounted inside it or
It is the change of violent natural environment, impact of such as strong convective weather etc., it is likely to make it rupture so as to service life drops
Low, need manually often maintenance and repair, have influence on the productive life of people, or even the security of the lives and property giving people causes prestige
The side of body.
