Rate hard aluminum wire and its production method.
Technical scheme
The main component of 99.7% commercial-purity aluminium is mainly Fe, Si, Cr, Mn, V, Ti in addition to aluminum.Wherein Cr, Mn, V, Ti master
Precipitation removal can be formed by adding B formation borides, Fe, Si do not come out, although forming rare earth by adding rare earth
Slag can remove part Fe, Si, but have an impact to conductance and intensity.
In the presence of no Si, Fe can be separated out in the form of needle-like or sheet, influence conductance and intensity, certain when adding
After the Si of amount, the precipitation state of iron is changed into bar-shaped or spherical, improves the conductance and obdurability of aluminum conductor to a certain extent.But
Si solid solubility in aluminium conductance is influenceed greatly it is also big, to improve final conductance and to ensure that enough intensity reaches L4 hard
The requirement of aluminum conductor also needs to be changed into more silicon from solid solution state to separate out state.

Compound, wherein with Fe3Si is the most stable.Fe3Si fusing points are 1069 DEG C, are solid-state in aluminium solution, micro-nano Fe3Si is analysed
Certain alterant can be played a part of by going out.
Calculated according to atomic weight, Fe3Si、α(Al12Fe3Si2)、Fe5Si3、β(Al9Fe2Si2)、FeSi2The Fe/Si of compound
Mass ratio is respectively 5.57,3.33,3,2,1.Matched in theory by the Fe/Si mass ratioes and ferrosilicon reaction can be achieved, it is real
Existing silicon is changed into separating out state from solid solution state, but the solubility actually due to Fe in aluminium is smaller, and the solubility of silicon is larger, largely
Iron is with Al3Fe forms are present, the silicon and free Al being dissolved in aluminium3Fe is not completely attached to, and is existed in aluminum melt
Uneven components, Fe, the Si being proportionally added into show as Fe excess, and excessive Fe is with Al3Fe is separated out with pin, rod, ball-type, shadow
Ring conductance.
Experiment finds that Fe/Si mass ratioes are more satisfactory by 3.54~5.26 conductances.
By Fe3Si parts corresponding to the Fe that Fe/Si mass ratioes 5.57 add less in Si compounds are with other compound forms
Separate out, be partly solid-solubilized in aluminum melt.Aluminum melt containing Si forms needle-like dendrite in cooling, influences conductance and intensity.Sb
It is a kind of alterant of aluminium liquid, adding Sb can prevent needle-like dendrite from developing, and justify dendrite profile blunt, crystal grain is tiny.Added
Fragility simple substance Sb, which can at most be formed, influences conductance and intensity, or sinks to furnace bottom and cause to waste.Sb addition is containing with Si
What amount determined, experiment finds that Si/Sb mass ratioes are that 13~22 conductances and intensity are more satisfactory.
Sb proportions are 6.697g/cm3, and the solubility in aluminum melt is minimum, and small particle can play alterant
Effect, crystal grain thinning improves intensity, but big particulate elemental can form brittle secondary phase influence intensity, therefore is uniformly added into Sb
It is crucial.Sb in Al-Sb intermediate alloys is with existing for block secondary simple substance phase, should melt dilution in proportion during use, use
Inert gas is blown into stove top layer and stirred immediately.Start to pour into a mould after 5~15 minutes, overlong time can cause upper and lower composition of layer not
.
