Fremgangsmåte og anordning for. elektrolytisk met al lm ant li g av aluminiumstråd. Method and device for. electrolytic metal lm ant li g of aluminum wire.
'Foreliggende oppfinnelse vedrører en fremgangsmåte for elektrolytisk metallmantling av aluminiumstråd og en anordning for å gjennomføre denne fremgangsmåte. The present invention relates to a method for electrolytic metal coating of aluminum wire and a device for carrying out this method.
Metallisk mantlet aluminiumstråd, særlig fortinnet aluminiumstråd,Metallic sheathed aluminum wire, in particular tinned aluminum wire,
er i første rekke beregnet for bruk i elektroindustrien, siden lodde-forbindelser mellom ledere på aluminiumsbasis uten metallisk mantling av tråden vanskelig eller overhodet ikke kan fremstilles. Metallisk mantlet aluminiumstråd beskytter dessuten denne mot angrep av syrer som dannes ved mantling med gummi eller plast. is primarily intended for use in the electrical industry, since soldered connections between aluminum-based conductors without metallic sheathing of the wire are difficult or impossible to produce at all. Metallic sheathed aluminum wire also protects this against attack by acids that are formed when sheathed with rubber or plastic.
Siden den umiddelbare oksydasjon av aluminiumstrådens flate ved til-virkningen gjør påleggingen av metallisk mantling meget vanskelig, har man allerede foreslått å forsyne trådflaten på elektrokjemisk veg først med et riktignok meget tynt sinkskikt, på hvilken metallmant-lingene på vanlig sett blir pålagt elektrolytisk. Denne fremgangsmåte og de resultater som derved oppnås har hittil ikke kunnet slå gjennom i praktisk bruk, særlig på grunn av ømfintligheten til xLettytterst tynne sink-mellomskikt. Since the immediate oxidation of the surface of the aluminum wire during production makes the application of a metallic sheath very difficult, it has already been proposed to provide the surface of the wire electrochemically first with an admittedly very thin layer of zinc, on which the metal sheaths are normally applied electrolytically. This method and the results obtained thereby have so far not been able to succeed in practical use, particularly due to the sensitivity of extremely thin zinc interlayers.
Et formål med oppfinnelsen er å fremstille en uømfintlig, varig for-bindelse mellom metallmantelen og aluminiumstrådens flate. One purpose of the invention is to produce an insensitive, permanent connection between the metal jacket and the surface of the aluminum wire.
Dette og andre formål oppnås ifølge oppfinnelsen ved at den avfettete og beisete tråden i et trekketrinn, som slutter seg umiddelbart til beisetririnét under avstengning av luft, gjennomløper et eller flere elektrolytiske metallmantlingsbad. Etter metallmantlingsbadet kan, som oppfinnelsen videre forutsetter, kobles et ytterligere trekketrinn for flatefortefning av den pålagte metallmantlingen og i en anordning for å gjennomføre denne fremgangsmåten skal ifølge oppfinnelsen beisebadet skilles fra det første elektrolytiske metallmantlingsbadet og fra de etterfølgende bad ved hjelp av trekkestener. Trekkestenene kan herunder danne metallmantlingsbadets katoder. Etter disse bad følger på kjent måte kald- og varmskyllingsbad med passivering. Fremgangsmåten tillater behandling med en streng i reverseringsdrift eller med flere strenger i drift i en retning. This and other purposes are achieved according to the invention by the fact that the degreased and stained thread in a drawing step, which immediately joins the staining tririne while shutting off air, runs through one or more electrolytic metal coating baths. After the metal sheathing bath, as the invention further assumes, a further drawing step can be connected for surface strengthening of the applied metal sheathing and in a device for carrying out this method, according to the invention, the pickling bath must be separated from the first electrolytic metal sheathing bath and from the subsequent baths by means of drawing stones. The drawing stones can also form the cathodes of the metal cladding bath. These baths are followed in the usual way by cold and hot rinsing baths with passivation. The method allows treatment with one string in reverse operation or with several strings operating in one direction.
Oppfinnelsen er nedenfor beskrevet nærmere under henvisning til den medfølgende tegning som viser et utførelseseksempel. The invention is described below in more detail with reference to the accompanying drawing which shows an exemplary embodiment.
Traden 1 påvirkes først av avstrykningsstrålen fra et luftmunnstykke 15 og når deretter inn i et avfettningsbad 2. I dette er det anordnet overløpsvegger 8 og anoder 11. Avfettningsløsningen pumpes fra en samlebeholder 17 ved hjelp av en pumpe 16 inn i badet 2 og løper med fritt fall tilbake til samlebeholderen 17. Tråden forlater deretter avfettningsbadet 2 og når gjennom en skillevegg 20 under avstrykningsstrålen fra et luftmunnstykke 21 over en overløpsvegg 22 inn i et beisebad 3. Ved slutten av dette bad er det anordnet en skillevegg 23 med en trekkesten 10. Anodene til det elektrolytiske arbeidende beisebad er betegnet med 12. Beiseløsningen når fra samlebeholderen 18 over en pumpe 24 inn i badet og løper deretter til-bake til samlebeholderen 18. Gjennom trekkestenen 10 når tråden uten å ha vært i berøring med luftens surstoff gjennom skilleveggen 2 3 inn i metallmantlingsbadet 4 og forlater dette gjennom en trekkesten 26 som er anordnet i en skillevegg 25. Metallmantlingsbadet 4 er forsynt med anoder 13 og forbindes over en pumpe 27 med en samlebeholder 19 ana-logt med forholdet ved de foran nevnte bad. Trekkestenene 10 og 28 tjener ved dette utførelseseksempel samtidig som katoder i metallmantlingsbadet 4. The tread 1 is first affected by the wiping jet from an air nozzle 15 and then reaches a degreasing bath 2. In this, overflow walls 8 and anodes 11 are arranged. The degreasing solution is pumped from a collecting container 17 by means of a pump 16 into the bath 2 and runs freely fall back to the collection container 17. The wire then leaves the degreasing bath 2 and reaches through a partition 20 under the wiping jet from an air nozzle 21 over an overflow wall 22 into a pickling bath 3. At the end of this bath a partition 23 is arranged with a drawing stone 10. The anodes to the electrolytic working pickling bath is denoted by 12. The pickling solution reaches from the collection container 18 via a pump 24 into the bath and then runs back to the collection container 18. Through the drawing stone 10, the thread reaches without having been in contact with the oxygen of the air through the partition 2 3 into the metal jacketing bath 4 and leaves this through a draw stone 26 which is arranged in a partition wall 25. The metal jacketing bath 4 is provided with anodes 13 and is connected via a pump 27 to a collection container 19 analogously to the situation in the aforementioned baths. In this embodiment, the drawing stones 10 and 28 simultaneously serve as cathodes in the metal cladding bath 4.
Den ferdigmantlete og flatefortettede aluminiumstråd når over ruller 14 Inn i et kaldskyllingsbad 5, et varmskyllingsbad 6 og deretter inn i et passiveringsbad' 7,; hvorfra den kan mates videre til ytterligere bearbeidingstrinn. The pre-sheathed and surface-densified aluminum wire reaches over rolls 14 into a cold rinse bath 5, a hot rinse bath 6 and then into a passivation bath' 7; from where it can be fed on to further processing steps.
