Abstract
The present invention discloses an aluminium clad iron wire and its production method and application. Said invention is characterized by that the iron wire is covered with a layer of aluminium layer, and the obtained aluminium clad iron wire can be made into the hanger chord for current-carrying messenger cable in the electrified railway construction. Said invented hanger chord is durable, can greatly reduce the replacement and maintenance cost, and the carbon content of the adopted iron wire is below 0.14%, so that its toughness is good, and the labour intensity for making hanger chord can be reduced, and the alumium is good conductor, it is not easy to strike arc and spark, and can reduce fault.
Description
The present invention relates to a kind of structure of cable, preparation method and purposes.Especially a kind of wire rope of suspended cables.
At present, railway in electrification is built, the dropper that is used on the current carrying catenary all adopts galvanized wire to make, and the dropper of making of galvanized wire, its zinc coat very easily corrodes in atmosphere and gets rusty, and has both influenced service life, influences serviceability again, generally just needed to change at three months to 1 year, and when changing, the workman needs hanging operation, thereby, replacing safeguards that labour intensity is big, the maintenance cost height also influences safe train operation, simultaneously, contact owing to form between poor conductor and the good conductor, easily starting the arc sparking, the generation that causes the accident, therefore, which kind of product to replace galvanized wire with, become electric railway design department technical problem anxious to be solved as the dropper on the current carrying catenary.
The object of the present invention is to provide a kind of Corrosion Protection good, the wire rope of long service life, this kind wire rope are mainly used in the dropper of making on the electric railway current carrying catenary, when hanging wire is made dropper, easily operation, and can form good conductor with cable and contact.
Technical scheme of the present invention is: aluminium iron clad silk is to coat one deck aluminium lamination on iron wire, and described iron wire phosphorus content is below 0.14%, and diameter is 3.0-5.5mm, and tensile strength is 300-400N/mm
2, the aluminum layer thickness that coats on iron wire is 0.25-0.75mm.
The preparation method of aluminium iron clad silk is: select the iron wire of phosphorus content at 0.14% following grade of steel, the bundled diameter that is drawn to is after the 3.0-5.5mm, to carry out annealing in process, and the tensile strength that makes iron wire is 300-400N/mm
2Scope, then the bundled iron wire after the heat treatment is carried out pickling, neutralization, rinsing, the aluminium bar that will meet GB GB3954-83 again carries out continuously extruded coating with the iron wire of handling well, the thickness that makes outer aluminium coating is at 0.25-0.75mm, the aluminium iron clad screw mandrel material that extrudes out, aluminium iron clad silk for a kind of model, the aluminium iron clad screw mandrel material that extrudes is out carried out the continuous high speed drawing again, drawing total deformation intensity is about 50%, make iron wire and the homogeneous deformation simultaneously of outer aluminium coating, the aluminium iron clad silk that forms, diameter is 3.0-50mm, tensile strength is 400-500N/mm
2, the outsourcing aluminum layer thickness is that 0.15-0.6mm is a kind of aluminium iron clad silk of model.
The purposes of aluminium iron clad silk is the dropper that is used to make on the electric railway current carrying catenary.
The present invention since in iron wire outside the tight thick aluminium lamination of parcel one deck, and be worked structure, rather than cast sturcture, so Corrosion Protection is good, is used to make the dropper on the electric railway current carrying catenary in conjunction with this good aluminium lamination.In humidity or acid rain serious area, also withstand corrosion, the life-span is more than 10 years, the general area life-span more than 15 years, thereby, reduced maintenance cost and Master Cost greatly; Because adopt the low-carbon (LC) iron wire, pliability is better, processing ease when hanging wire is made dropper, convenient, reduce labor intensity, because aluminium is good conductor, dropper forms good conductor with cable and contacts with good conductor, can not produce starting the arc sparking phenomenon, the generation of minimizing accident.
Below in conjunction with accompanying drawing the present invention is described in further detail:
Fig. 1 is the section figure of aluminium iron clad silk of the present invention
Fig. 2 is the front view of the dropper of aluminium iron clad silk making of the present invention
As shown in Figure 1, coat one deck aluminium lamination at iron wire 1, the iron wire diameter is 3.0-5.5mm, and tensile strength is 300-400N/mm
2, the aluminum layer thickness that coats on iron wire is 0.25-0.75mm.
The preparation method of aluminium iron clad silk: select the iron wire of phosphorus content at 0.14% following grade of steel, the bundled diameter that is drawn to is after the 3.0-5.5mm, to carry out annealing in process, and the tensile strength that makes iron wire is 300-400N/mm
2Scope, then the bundled iron wire after the heat treatment is carried out pickling, neutralization, rinsing, aluminium bar with precedent GB GB3954-83 carries out continuously extruded coating with the iron wire of handling well again, the thickness that makes outer aluminium coating is at 0.25-0.75mm, the aluminium iron clad screw mandrel material that extrudes out, this is a kind of aluminium iron clad silk of model, the aluminium iron clad screw mandrel material that extrudes is out carried out the continuous high speed drawing again, drawing total deformation intensity is about 50%, make iron wire and the homogeneous deformation simultaneously of outer aluminium coating, the aluminium iron clad silk of Xing Chenging at last, diameter is 3.0-5.0mm, tensile strength is 400-500N/mm
2, the outsourcing aluminum layer thickness is 0.16-0.6mm, this is the aluminium iron clad silk of another kind of model.
The main application of aluminium iron clad silk is the dropper that is used to make on the electric railway current carrying catenary, and Fig. 2 is the front view of the dropper of aluminium iron clad silk making.
