The invention relates to an aluminium magnesium alloy wire for cable braided shield and production method thereof, which contains, in weight percentage, 3.2-3.9% magnesium, 0.15-0.35% chromium, 0.1-0.5% boron, and the surplus is aluminum. Its production methods is: carrying out the production on the raw material having boron according to the process of smelting, primary stretch forming, heat treatment, rough drawing, secondary drawing, heat treatment, carefully drawing, and a automatically monitored tubular annealing process that is adopted after the carefully drawing process. The aluminium magnesium alloy wire for cable braided shield adopting the present inventive rate, has a resistivity no more thatn 0.051 omega.mm[2]/m in 20 DEG C, which reaches a level of the foreign similar advanced product; the aluminium magnesium alloy wire for cable braided shield produced by the present inventive method, has a break force no less than 5.1N, and a breaking elongationoun rate no less than 10%.
Description
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.
Technical background
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 this cable braid shielded is significantly improved with the pull-off force and the elongation at break of aluminum-magnesium alloy wire.
For achieving the above object, cable braid shielded aluminum-magnesium alloy wire of the present invention contains weight percent magnesium 3.2-3.9%, chromium 0.15-0.35%, surplus is an aluminium, and it also contains boron 0.1-0.5%.
The content of described boron is 0.25-0.3%.
The cable braid shielded with the technical process of the production method of aluminum-magnesium alloy wire is: melting-first pulling shaping-thermal treatment-rough-in draw-thermal treatment-carefully draw-multifilament-check warehouse-in, to be furnished with the raw material of boron and produce, and carefully draw and adopt the tubular type annealing process of monitoring automatically after the operation by described flow process.
The tubular type annealing process of described automatic monitoring is that the silk volume is annealed through the tubular type annealing furnace from paying out machine, 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 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 ℃
