Abstract
The utility model relates to a steel fiber copper covered steel wire comprising a drawing outer copper layer. An Ag-Ni-Nb compo pipe is arranged inside the drawing outer copper layer. A copper covered steel fiber bundle is arranged inside the Ag-Ni-Nb compo pipe. The copper covered steel fiber bundle comprises a plurality of copper covered steel fibers. The copper covered steel fibers comprise steel fibers and copper pipes which sleeve the steel fibers. The utility model employs the Ag-Ni-Nb compo pipe, so that solid solution of iron in surface layers of copper layers can be further prevented; the conductivity is raised; the conductivity is 38%-43% IACS; and the tensile strength can reach above 1100Mpa.
Description
Technical field
The utility model relates to a kind of steel fibre copper covered steel wire.
Background technology
Copper has good electric conductivity, but expensive, and hardness, hot strength is on the low side.Steel has good mechanical performance, but conductance is low, decay resistance deficiency.The copper covered steel copper layer thickness that galvanoplastic are produced is at present lower, only 0.25mm-0.5mm.Under hot conditions, iron solubility in copper is larger, but low temperature separates out slowly, and the iron atom of solid solution is by the conductance of very large reduction copper covered steel.Iron residual in copper base has great impact to electric conductivity, often dissolves in 0.1% iron in copper matrix, can make electric conductivity decline 30%, and heat treatment time is long, easily makes fiber alligatoring, directly causes the strength of materials to reduce.Therefore there is the low and low deficiency of intensity of conductance in existing steel fibre copper covered steel wire.
Summary of the invention
The utility model object is to overcome above-mentioned the deficiencies in the prior art and a kind of steel fibre copper covered steel wire is provided, and this steel fibre copper covered steel wire has advantages of high conductivity and high tensile.
The technical scheme that realizes the employing of the utility model object is: a kind of steel fibre copper covered steel wire comprises: the outer copper layer of drawing, in the outer copper layer of described drawing, be provided with Ag-Ni-Nb compo pipe, in described Ag-Ni-Nb compo pipe, be provided with copper covered steel fibre bundle, described copper covered steel fibre bundle comprises multiple copper covered steel fibers, and described copper covered steel fiber comprises steel fibre and is placed on the copper pipe outside described steel fibre.
In technique scheme, described steel fibre diameter is 1mm.
In technique scheme, the thickness of described Ag-Ni-Nb compo pipe is 1～2mm.
The utlity model has following advantage:
1, after testing, the utility model steel fibre copper covered steel wire conductance is 38%-43%IACS, more than hot strength can reach 1100Mpa.
2, the Ag-Ni-Nb compo pipe in the utility model has further prevented the solid solution of iron in the copper layer of top layer, has improved conductance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model steel fibre copper covered steel wire.
In figure, 1-steel fibre, 2-copper pipe, 3-Ag-Ni-Nb compo pipe, the outer copper layer of 4-drawing.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, steel fibre copper covered steel wire comprises: the outer copper layer 4 of drawing of tubulose, Ag-Ni-Nb compo pipe 3 is located at the inwall of the outer copper layer 4 of drawing closely, in Ag-Ni-Nb compo pipe 3, be provided with copper covered steel fibre bundle, described copper covered steel fibre bundle comprises multiple copper covered steel fibers, and copper covered steel fiber comprises steel fibre 1 and is placed on the copper pipe 2 outside steel fibre 1.
In the present embodiment, steel fibre 1 diameter is preferably 1mm, and the thickness of Ag-Ni-Nb compo pipe is 1～2mm.
Because Ag, Ni, tri-kinds of Metal Phases of Nb are for Fe, more approaching with Cu atomic radius, in the middle of copper covered steel twisted wire, add this transition zone and can further prevent the solid solution of iron atom in copper, compare in the copper matrix of existing market copper covered steel used and often dissolve in 0.1% iron, its electric conductivity declines 30%, the utility model can further prevent the solid solution of iron in the copper layer of top layer after adopting Ag-Ni-Nb compo pipe, has improved conductance.In addition, the copper covered steel fiber of inner fiber shape can further strengthen overall mechanical performance.
After testing, the utility model steel fibre copper covered steel wire conductance is 38%-43%IACS, more than hot strength can reach 1100Mpa.
