Description
The present invention relates to a kind of manufacture method of single wire drawing high-strength copper-clad steel wire, belong to metallurgical class.
Welding wire is widely used in fields such as post and telecommunications, coaxial cable, ultra-high-tension power transmission line, electronic component down-lead.For welding wire, two kinds of methods are arranged at present: 1, steel wire is carried out copper facing, in electroplating process, add brightness and density that the cyanide additive guarantees the copper layer; 2, with the copper facing of mild steel wire elder generation, carry out wire drawing then, through more than ten drawings, make steel wire and copper plate carry out bulk deformation, from the coarse to fine, the drawing deformation amount is 80%, and tensile strength is 800MPa.
The disadvantages of background technology part is: 1, cyanide copper plating is poisonous, pollution is big, technology controlling and process is complicated, cost is high; 2, mild steel wire plates post-tensioning earlier, and welding wire intensity is low, complex process.
The manufacture method that the objective of the invention is to overcome the weak point of above-mentioned background technology and a kind of single wire drawing high-strength copper-clad steel wire is provided, it can produce best bright finish, high-compactness, high-intensity welding wire.
The present invention can reach by following measure: with diameter is that the steel wire of 0.64～3.2mm is a core, and copper plate outside steel wire carries out the single pass drawing with 20～150 meters/minute pulling rates to coppered steel wire, and the drawing compression ratio is 2～5%.
The intensity of bullet wire, high-carbon steel wire and copper plate is inconsistent, can't carry out the drawing of multi-pass, and wire quality of the present invention is medium carbon steel, high-carbon steel, and the heart yearn of gauge of wire and finished product welding wire is equal to, and diameter is 0.64～3.2mm.Then steel wire is carried out copper facing, thickness of coated copper layer is 30～85 μ, on wire drawing machine, carry out single wire drawing, the purpose of drawing is to make the welding wire that has plated copper that less deflection be arranged, wire-core is indeformable, drawing is to draw to dial the copper layer purely, the copper plate of steel wire is not a bulk deformation, behind drawing coating, can make strong bonded between copper layer and the wire-core, and increased the density of copper plate, control the tolerance diameter, increased the brightness of copper plate, increased welding wire surface oxidation-resistant performance, because wire-core is a high-carbon steel wire, bullet wire has then guaranteed the high strength of welding wire.
Characteristics of the present invention are: make heart yearn with high, bullet wire, carry out single wire drawing after the copper facing.
Below in conjunction with embodiment the present invention is further set forth:
To make diameter is that the welding wire of 1.02mm is an example, and the 0.88mm high-carbon steel wire is carried out copper facing, and its technological process is that high-carbon steel wire → pickling → water flushing → preplating → water flushing → copper facing → water flushing → hot water wash → oven dry → single wire drawing → take-up is packed.Pickling adopts sulfuric acid to carry out cathodic pickling; Preplating is nickel plating, adopts sulfate; Sulfate is adopted in copper facing.Welding wire diameter after the copper facing is φ 1.03mm, carries out single wire drawing with 100 meters/minute drawing speeies on the LW-1/350 single-head wire drawer, and the drawing hole is φ 1.02mm, and finished product is the welding wire of diameter phi 1.02mm, coils the 300Kg that weighs.Welding wire tensile strength is 1400MPa, and conductance is greater than 30%, and resistivity is reversed greater than 20 times rupture pull force 1100N less than 72 Ω.
The present invention has compared following advantage with background technology:
1, process is simple, and production cost is low;
2, welding wire intensity height, the surface brightness height, oxidation resistance is strong;
3, can produce the Kinds of Heavy Coil welding wire.
