Summary of the invention
Goal of the invention:The purpose of this invention is to provide a kind of rare-earth aluminum alloy lead wire, adopt aluminium alloy conductor of the present invention to have simultaneously excellent electrical, thermal endurance, wear-resisting and decay resistance, use more safe and reliable as wire.
Technical scheme:For achieving the above object, the present invention is by the following technical solutions: rare earth aluminum alloy material is content by weight percentage, it comprises the Fe of following component: 0.01 ~ 1wt%, 0.01 the Cu of ~ 1wt%, the B of 0.01 ~ 1wt%, the Si of 0.01 ~ 0.5wt%, 0.01 the Mg of ~ 0.1wt%, 0.01 the Zn of ~ 0.1wt%, the rare earth element of 0.01 ~ 1wt%, all the other are aluminium and inevitable impurity.
A kind of rare earth aluminum alloy material, described rare earth element are one or more compositions in Sc, Y, La, Ce, Pr, Nd.
Add the proportional alloy of aluminium ingot and respective sets in shaft furnace, make temperature remain on 730 ~ 780 ℃, add above-mentioned alloying element in molten aluminium, alloying element is that the form with intermediate alloy adds, through stirring, refining, slagging-off, carry out the stokehold sample analysis after 40 minutes, cast the aluminium alloy cast bar in milling train.The aluminium alloy cast bar is imported milling train, and the temperature that imports milling train is 450 ~ 500 ℃, and it is 260 ~ 330 ℃ that the derivation milling train becomes the finishing temperature of aluminium alloy rod.Finally by cold drawn, be stranding into rare-earth aluminum alloy lead wire.
Beneficial effect:
1. the rare-earth aluminum alloy lead wire for preparing by the present invention has excellent electrical property, anti-wear performance, heat resistance and decay resistance.
2. add the rare earth element of 0.01 ~ 1wt% in the present invention, its rare earth elements is comprised of one or more in Sc, Y, La, Ce, Pr, Nd, Sc, Y, La, Ce, Pr, Nd have removal of impurities preferably and improve alloy corrosion resistance can effect.Strengthened accordingly and fine and close because the filling of rare earth element makes surface film oxide, this has improved the corrosion resisting property of platform gold greatly, is no matter that rare earth all is improved the effect of corrosion resisting property in the electrochemical corrosion of the anti-oxidant and normal temperature of high temperature.And this effect is more obvious with corrosion process.This is obviously the Al due to the rare earth of corrosion oxidation process formation
2O
3Film has better anti-corrosion effect.Not only ability general corrosion, and to chloride ion, sodium ion, H
2S, CO
2, SO
2With heavy corrosion conditions such as fluorine ions, effect is preferably arranged.Wherein Sc and Y also have the stable on heating effect of the alloy of raising.
3. rare earth and B add alloy mainly to play to carry heavy alloyed electric conductivity, and can put forward heavy alloyed processing characteristics by crystal grain thinning.
4. the Mg that also adds in the present invention and Fe, these elements have comparatively significantly effect to the thermal endurance that improves aluminium alloy, the percentage composition that adds 0.01 ~ 1wt% can make the long-time running temperature of aluminium alloy bring up to 150 ℃, improves the thermal stability of aluminium alloy long-time running.
5. add Cu and Si to play in the present invention to carry heavy alloyed intensity effect, a certain amount of Zn to add wherein and play good effect for carrying heavy alloyed anti-wear performance, guardwire, carry heavy alloyed useful life preferably.
