Description

Cable braid shielded aluminum-magnesium alloy wire and production method thereof
Technical field
The present invention relates to cable the braid shielded aluminum-magnesium alloy wire and the production method thereof of concentric cable industries such as a kind of CATV of being widely used in.
Background technology
The braid of CATV concentric cable is originally the employing tinned copper wire, and, anti-couple-corrosion low because of aluminum-magnesium alloy wire light specific gravity, cost and recovery value be low can to prevent characteristics such as pilferage, is replacing tinned copper wire gradually.Production cable braid shielded is such with the proportioning raw materials of aluminum-magnesium alloy wire at present: it comprises that magnesium 3.2-3.9%, chromium 0.15-0.35%, surplus are aluminium, chromium combines with elements such as magnaliums as a kind of main reinforcement element, can improve intensity of aluminum alloy, corrosion-resistant, antirust and make product surface gloss; But the aluminum-magnesium alloy wire of proportioning like this, its resistivity≤0.05388 Ω mm in the time of 20 ℃ 2/ m can meet domestic standard, also has distance with international standard.Its existing production method is: melting-first pulling shaping-thermal treatment-rough-in draw-thermal treatment-carefully draw-multifilament-check warehouse-in.Adopt the aluminum-magnesium alloy wire of this explained hereafter, its pull-off force and elongation at break are all not ideal enough.
Summary of the invention
Resistivity when the purpose of this invention is to provide a kind of 20 ℃≤0.051 Ω mm 2The cable braid shielded aluminum-magnesium alloy wire of/m, and the production method that significantly improves with the pull-off force and the elongation at break of aluminum-magnesium alloy wire of this cable braid shielded.
For achieving the above object, the technical solution used in the present invention is that the cable braid shielded is made up of following raw materials by weight percent with aluminum-magnesium alloy wire:
Magnesium 3.2-3.9%;
Chromium 0.15-0.35%;
Boron 0.1-0.5%;
Surplus is an aluminium.
The content of described boron is 0.25-0.3% (weight).
Cable braid shielded of the present invention with the production method that aluminum-magnesium alloy wire adopts is: with raw material magnesium 3.2-3.9%, chromium 0.15-0.35%, boron 0.1-0.5%, surplus aluminium, melting-first pulling shaping-thermal treatment-rough-in draw-thermal treatment-carefully draw, silk package after carefully drawing is on paying out machine, the silk volume is annealed through the tubular type annealing furnace from paying out machine, when rotating speed during in the speed that 800-1000 changes, temperature is controlled at 380-430 ℃, by time and the temperature in the automatic monitored control system control annealing process, again through being around on the take-up reel of wire coiler check warehouse-in behind the multifilament after the anti-oxidation processing.
Adopt the cable braid shielded aluminum-magnesium alloy wire of proportioning of the present invention, its resistivity≤0.051 Ω mm in the time of 20 ℃ 2/ m reaches external similar advanced product level; The cable braid shielded aluminum-magnesium alloy wire that adopts the inventive method to produce, pull-off force 〉=5.1N, elongation at break 〉=10%.
