Abstract
Do are a kind of 3003 aluminium alloy electronics foil blank aging thermal treating process, rolled down to original hot rolling or cast-rolling stock When thick, adopt high temperature homogenizing annealing processing, make even tissue, weaken segregation; After annealing, multi-pass is cold rolling continuously, extremelyWhen thickness, carry out full annealing treatment process, to weaken residual stress; Continuing multi-pass is cold-rolled to, directly transferring paper tinsel to and roll, multi-pass paper tinsel is rolled toWhen thickness, carry outAgeing Treatment, has realized the pattern of second-phase and the control of distribution to aluminium alloy electronics foil blank; After Ageing Treatment, be rolled to finished product thickness through paper tinsel repeatedly. The present invention is by implementing specific Technology for Heating Processing to this 3003 aluminium alloy electronics foil blank, realized to the second phase particles in 3003 aluminium alloys (Phase) control of form and distribution, its a large amount of disperses are uniformly distributed, by using this blank, later stage corrosive effect is good, improves this aluminium alloy electronics paper tinsel specific capacitance, can reach
Description
Technical field
The present invention relates to a kind of aging treatment method of 3003 aluminium alloy electronics foil blanks, is mainly to produceThe aging thermal treating process of electronics aluminum foil stock for the aluminium electrolutic capacitor of thickness.
Background technology
The various fields such as that aluminium foil is widely used in is electric, packaging, building, and apply range along with the development in epoch alsoStrengthen, product quality is also had higher requirement. 3003 aluminium alloy electronics paper tinsels are that one is widely used in alminium electrolytic condenserThe aluminium foil of device. Because complete electronic set is rapidly to short, little, light, thin future development, force aluminium electrolutic capacitor must accelerate miniaturizationWith microminiaturized process. The key of aluminum capacitor miniaturization is the gigantism of aluminum electric pole foil effective surface area, this antianode aluminiumPaper tinsel has proposed to be strict with very much, also requires its supporting cathode aluminum foil to possess excellent performance, especially cathode aluminum foil simultaneouslySpecific capacitance because cathode foil for aluminum electrolytic capacitors specific capacitance height affect equally aluminium electrolutic capacitor volume greatlyLittle. The aluminium alloy Cathode Foil valency a large amount of a large amount of high-specific capacitance supers of the annual import of China is large, has restricted to a great extent China's electricityThe international competitiveness of sub-industrial expansion and aluminium processing enterprise.
In 3003 aluminium alloys containing Mn second-phase compound to separate out alloy Effect on Mechanical Properties very little, but these are analysed containing MnGoing out for aluminum substrate is weak negative electrode phase, can produce the etch pit of " cavernous body " shape when chemical etching technology,Effectively increase surface area, be conducive to the raising of electronics paper tinsel specific capacitance.
The approach that improves aluminum foil stock microscopic structure is improved the quality of electronics paper tinsel, reasonably subsequent machining technology this twoBar. Although 3003 aluminium alloys belong to not heat-treatable strengthened alloy, in actual production, conventionally do not carry out timeliness heat treatment.
Summary of the invention
Object of the present invention: a kind of 3003 aluminium alloy electronics foil blank aging treatment process are provided, can Effective Regulation3003 finished product aluminum foil stock second-phase forms, achieve even, disperse distribution; By 3003 aluminium alloy electrics under this techniqueSub-foil blank corrosion, realizes the increase of specific capacitance.
The technical solution used in the present invention: aluminum foil stock is realized in the operation of rolling to high-temperature annealing process, completely middleThe combination of annealing process and aging thermal treating process; In the artificial aging Technology for Heating Processing that the rolling later stage carries out, realize 3003Control to second-phase form and distribution in the alloy foil operation of rolling.
1) be hot-rolled down to by hot rolling blank (cast-rolling stock), carry out homogenizing annealing, mechanism of anneal at this thicknessFor。
2) through multi-pass cold-rolling process, rollWhen thickness, carry outFull annealing technique.
3) continue to be cold-rolled to, then transfer paper tinsel to and roll, produce through multi-pass paper tinsel roll process,When thickness, carry outArtificial aging processing, separates out second-phase in a large number, and disperse evenly dividesCloth.
4), after multi-pass paper tinsel roll process, select to generateThe aluminium foil of different-thickness in scope,Generate finished product aluminium alloy electronics foil blank, this finished product electronics paper tinsel is carried outFinished product aging treatment process.
By this 3003 aluminium alloy electronics foil blank is implemented to specific Technology for Heating Processing, the present invention has realized 3003 aluminiumSecond phase particles in alloy (Phase) control of form and distribution, its a large amount of disperses are uniformly distributed, be somebody's turn to do by useBlank, later stage corrosive effect is good, improves this aluminium alloy electronics paper tinsel specific capacitance, can reach。
