Abstract
A technology for making electrically conductive steel-in-copper bimetal wire includes heat treatment of steel wire, cleaning copper band and steel wire, wrapping steel wire with copper band, welding the connecting seam of copper band, stretching, and final heat treatment. Its advantages are simple operation and high quality of product.
Description
The invention belongs to a kind of production method of metal wire rod, particularly a kind of production method of copper covered steel bimetallic wire.
Galvanoplastic are arranged, in steel wire electroplating surface layer of copper in the prior art.The shortcoming of its method is to mix matter in the copper layer, reduces the conductivity of copper layer; The intensity of copper steel combination is relatively poor; Cyanide electroplating liquid is poisonous, and environmental protection is had a significant impact, and can not directly discharge.In addition-kind of a method is molten copper infusion process, and steel wire after slicing mould strips off the skin, is carried out preheating, make it in the copper liquid of crucible insulation, to pass through, so on the steel wire surface just condensation layer of copper, carry out heating rolling more continuously.Last drawing obtains product.The used equipment of this kind method, technology are complicated, and it is hour wayward to coat volume ratio, and copper layer thickness is difficult to even distribution.Poor product quality, the cost height.
The purpose of this invention is to provide a kind of simple to operate, cost of equipment is low, the production method of the copper covered steel bimetallic wire of good product quality
Technical solution of the present invention is: a kind of production method of copper covered steel bimetallic wire is characterized in that: it comprises the steps:
A: steel wire is heat-treated;
B: copper strips and two kinds of raw material of steel wire are cleaned respectively;
C: copper strips is coated on the steel wire;
D: the longitudinal seam of welding copper strips;
E: stretch;
F: the final heat treatment of copper covered steel wire.
Method for annealing is adopted in described heat treatment to steel wire, and its temperature is 670 ℃-720 ℃, and the time is 1-2 hour.
Described to carrying out pickling processes after the steel wire heat treatment.
Described to carrying out straightening processing after the steel wire pickling.
Describedly copper strips is carried out degrease handle.
Describedly be welded as argon arc welding.
Described being stretched as after the first stretching repeatedly stretches again, and the reduction of cross sectional area when every time stretches is 15%-20%.
Described final heat treatment method is for to carry out in the vacuum gas filling annealing furnace, and its temperature is 600 ℃-650 ℃, and the time is 1-2 hour.
Advantage such as that the present invention compared with prior art has is simple to operate, cost of equipment is low, good product quality, production cost are low.
Below the present invention being done a step describes:
To produce diameter is 1.66mm, tensile strength 〉=400MPa, percentage elongation 〉=8.0%, dc resistivity≤0.08374 Ω mm
2The copper covered steel wire of/m is an example, and selecting thickness for use is the fine copper band of 0.25mm and No. 10 steel steel wires that diameter is 9.0mm.
Earlier steel wire is carried out annealing in process, its method is for to carry out in well formula annealing furnace, and temperature is controlled at 700 ℃, and the time was controlled at 1.5 hours.
Steel wire is carried out pickling processes, and its method is to carry out in the aqueous hydrochloric acid solution groove.
After the pickling steel wire is carried out straightening processing, can on wire-straightening machine, carry out.
Copper strips is carried out degrease handle, its method is for carrying out in cleaning the Ji groove.
Copper strips, steel wire are scrubbed processing, and this processing is carried out on the metal scrubbing unit.
Copper strips that pre-treatment is good and steel wire enter in the compounding machine with the speed of 10 meters of per minutes, and described compounding machine selects for use metallic cover equipment to get final product.In compounding machine, be full of the argon gas copper strips and progressively longitudinally be rolled into the pipe shape, steel wire is coated wherein by roller.Wire rod after the coating enters in the welding case on the compounding machine again, is 120 amperes argon arc welding welding longitudinal joint with electric current.The line base of postwelding, its copper pipe internal diameter form a gap between the two than the big 0.5mm of steel wire external diameter, are full of argon gas in it.Under argon gas does not unload leakage situation, directly enter in the stretching-machine subsequently and stretch for the first time.First stretching can be divided into twice to be carried out, and the drum diameter on the stretching-machine is 1 meter, and the wire drawing die aperture is respectively 8.9mm and 8.0mm.The back copper layer that stretches closely coats steel core.This line base continuously repeatedly stretches again, and this moment, the drum diameter of stretching-machine was 600mm, successively stretched by 18 passages, and the section total draught reaches more than 96%, and being pulled to diameter is that 1.66mm gets final product.For improving the plasticity of copper covered steel wire, the lead after stretching is carried out final heat treatment, in the vacuum gas filling annealing furnace, to carry out, temperature is 650 ℃, the time is 1.5 hours.Its tensile strength of copper covered steel lead through above-mentioned explained hereafter is 420MPa, and percentage elongation is 10%, and dc resistivity is 0.08105 Ω mm
2/ m.Copper steel reaches metallurgical binding.Destroy in any case, the interface of copper steel does not have lamination.
