Description

Anordning for belegning av metalltråd, -bånd eller lignende med et annet metall. Device for coating metal wire, tape or the like with another metal.

Den foreliggende oppfinnelse vedrorer en anordning for belegning av metalltråd, -bånd eller lignende med et annet metall eller metallegering fra en smelte, omfattende en hovedbeholder for smeiten og en i forbindelse med denne stående langsmal behandlingsbeholder med i forhold til hovedbeholderen lite volum, i hvilken behandlingsbeholdeis begge endepartier trekkskiver eller munnstykker for trådens passasje gjennom beholderen er anordnet. The present invention relates to a device for coating metal wire, strip or the like with another metal or metal alloy from a melt, comprising a main container for the smelting and a standing, elongated processing container with a small volume in relation to the main container, in which the processing container is both end sections draw discs or nozzles for the thread's passage through the container are provided.

Et stort antall fremgangsmåter for metallbelegning av tråd fra en smelte er kjente. Felles for de fleste er at tråden, som fores frem i en stort sett horisontal bane, ved brysthjul eller på annen måte, styres ned i og opp av smeiten. Disse kjente anordninger er beheftet med flere ulemper. Således gir boyningen over brysthjulene et visst ikke onskelig strekk av tråden. Videre kan tråden efter belegningen ikke boyes tilbake til den horison-tale bane for det pålagte metall er storknet, hvorfor kjoling av tråden må skje over smeiten med tråden i vertikal eller hel-lende bane og med luft som kjblemedium. En annen ulempe er at metallmengden i smeiten må være stor for at smeltens temperatur ikke altfor meget skal påvirkes ved påfylling av nytt materiale i form av barrer. A large number of methods for metal coating wire from a melt are known. Common to most is that the thread, which is fed forward in a mostly horizontal path, by breast wheels or in some other way, is guided down and up by the forge. These known devices are subject to several disadvantages. Thus, the bowing over the chest wheels gives a certain undesirable stretch of the thread. Furthermore, after the coating, the wire cannot be bent back to the horizontal path because the applied metal has solidified, which is why cooling of the wire must take place above the forge with the wire in a vertical or inclined path and with air as the cooling medium. Another disadvantage is that the amount of metal in the smelting must be large so that the temperature of the melt is not affected too much when new material is added in the form of ingots.

En annen ulempe er at i visse tilfelle, f. eks. ved fortinning av kobbertråd, må anordninger foreligge som ved stopp muliggjor at tråden raskt loftes ut av smeiten da ellers kobbertråden lo-ses opp av tinnet. Videre er det ved f. eks. fortinning av kobbertråd en ulempe at tråden for en del loser seg opp i det smel-tede tinn og at kobbergehalten efter hvert når slike verdier at en kobbertinnlegering utfelles i smeiten. Samtidig som dette medforer et tinntap, kreves også en regelmessig rengjbring av smeltebeholderen. En ytterligere ulempe er at de trekkskiver eller munnstykker av forskjellig form som tråden passerer, når den forlater smeiten, og hvilke har til oppgave å bestemme beleggets tykkelse, lett nedsmusses av forurensninger i smeiten, hvorved ujevnheter i det pålagte skikt oppstår. Another disadvantage is that in certain cases, e.g. when tinning copper wire, devices must be present which, when stopped, enable the wire to be lifted out of the smelter quickly, otherwise the copper wire will be loosened by the tin. Furthermore, it is by e.g. tinning of copper wire a disadvantage that the wire partially dissolves in the molten tin and that the copper content eventually reaches such values that a copper-tin alloy is precipitated in the smelting. While this entails a loss of tin, regular cleaning of the melting vessel is also required. A further disadvantage is that the drawing discs or nozzles of different shapes that the wire passes through when it leaves the forge, and which have the task of determining the thickness of the coating, are easily soiled by impurities in the forge, whereby unevenness in the applied layer occurs.

Disse og andre ulemper elimineres ifblge foreliggende oppfinnelse ved en anordning av den innledningsvis nevnte art som kjenneteg-nes ved at behandlingsbehblderen er horisontalt anordnet over hovedbeholderen og står i forbindelse med denne ved en kanal som med sin nedre ende dykker ned i hovedbeholderens smelte, gjennom hvilken kanal smelte under drift tilfores behandlingsbeholderen ved at trykket i denne beholder er regulert til en lavere verdi enn i hovedbeholderen. According to the present invention, these and other disadvantages are eliminated by a device of the type mentioned at the outset, which is characterized by the fact that the treatment container is horizontally arranged above the main container and is connected to it by a channel which, with its lower end, dips into the main container's melt, through which channel melt during operation is supplied to the treatment container by the fact that the pressure in this container is regulated to a lower value than in the main container.

Oppfinnelsen skal forklares nærmere under henvisning til tegningen, som viser et utfbrelseseksempel av en behandlingsbeholder. BehandlingsbehoIderen betegnes med 1 på tegningen og utgjores stort sett av et ror, som i hver ende er forsynt med et gjennom-føringsorgan eller et munnstykke 2 og 14, som slutter tett om-kring en gjennom behandlingsbeholderen trukket tråd 3. Med 4 betegnes en del av en smelte i en ikke vist hovedbeholder, over hvilken smelte behandlingsbeholderen er anordnet og med hvilken den står i forbindelse ved hjelp av en rorformet kanal 5, som munner ut under smeltens overflate. Med 6 betegnes en til behandlingsbeholderen tilsluttet og over denne anordnet ytterligere beholder, vakuumbeholder, som er forsynt med et av to deler, 7 og 8, bestå-ende tettsluttende lokk. I lokkdelen 8 finnes et organ 9, til hvilket en vakuumpumpe, ejektor eller lignende kan tilsluttes for evakuering av luften i vakuumbeholderen respektive behandlingsbeholderen ved driftens igangsetting. Ved evakuering stiger smeiten opp i og fyller helt behandlingsbeholderen og fortsetter siden opp i vakuumbeholderen, hvorved tilforselen av smelte styres ved hjelp av en elektrode 10 festet ved lokkdelen 8. Ved elektrodens kontakt med smeiten sluttes en stromkrets, som påvirker nevnte vakuumpumpe eller en magnetventil, slik at evakueringen avbrytes. Rundt behandlingsbeholderen, vakuumbeholderen og kana-len 5 er anordnet elektriske varmeelementer 11, med hvis hjelp temperaturen på den i behandlingsbeholderen forekommende del av smeiten kan reguleres. Behandlingsbeholderen, vakuumbeholderen og forbindelseskanalen er videre omgitt av et felles ytre hus 12. Rommet mellom det ytre hus og de elektriske varmeelementene er fylt med et varmeisolerende medium 13. Utover hva som vises på tegningen, finnes bl.a. en anordning for påforing av flussmiddel, som tråden passerer for den når inngangsmunnstykket 2 samt et vannbad, hvori tråden kjoles efter passeringen av behandlings-beholderens utgangsmunnstykke 14. The invention will be explained in more detail with reference to the drawing, which shows an exemplary embodiment of a treatment container. The treatment container is denoted by 1 in the drawing and generally consists of a tube, which is provided at each end with a lead-through or a nozzle 2 and 14, which closes tightly around a thread 3 drawn through the treatment container. 4 denotes a part of a melt in a main container, not shown, above which melt the treatment container is arranged and with which it is connected by means of a tube-shaped channel 5, which opens out below the surface of the melt. 6 denotes a further container connected to the processing container and arranged above it, a vacuum container, which is provided with one of two parts, 7 and 8, consisting of a tight-fitting lid. In the lid part 8, there is a device 9, to which a vacuum pump, ejector or the like can be connected to evacuate the air in the vacuum container or treatment container when the operation is started. During evacuation, the melt rises into and completely fills the processing container and continues up the side into the vacuum container, whereby the supply of melt is controlled by means of an electrode 10 attached to the lid part 8. When the electrode comes in contact with the melt, a circuit is closed, which affects the aforementioned vacuum pump or a solenoid valve, so that the evacuation is interrupted. Electric heating elements 11 are arranged around the treatment container, the vacuum container and the channel 5, with the help of which the temperature of the part of the melt found in the treatment container can be regulated. The treatment container, the vacuum container and the connection channel are further surrounded by a common outer housing 12. The space between the outer housing and the electric heating elements is filled with a heat-insulating medium 13. In addition to what is shown in the drawing, there are e.g. a device for applying flux, through which the thread passes before it reaches the inlet nozzle 2 and a water bath, in which the thread is coated after passing through the outlet nozzle 14 of the treatment container.

Ved belegningen av en metalltråd med metall fra en smelte med appa-ratet ifolge oppfinnelsen trekkes tråden gjennom behandlingsbeholderen i en rett, horisontal ubrutt bane, idet tråden bringes i kontakt med smeiten ved at luften i vakuum- og behandlingsbehol-derne evakueres gjennom organet 9. Herved suges smeiten opp i behandlings- og vakuumbeholderne til et av elektrodens 10 plasse-ring bestemt nivå. Elektroden utgjor den ene kontaktdel og smel-ten den andre kontaktdel i en stromkrets, som styrer evakueringen av vakuum- og behandlingsbeholderene ved f. eks. å påvirke en magnetventil innkoblet i en til organet 9 koblet evakueringsslange. Klaringen mellom tråden og utgangsmuhnstykket 14 bestemmer det pålagte skikts tykkelse. When coating a metal wire with metal from a melt with the apparatus according to the invention, the wire is drawn through the treatment container in a straight, horizontal, unbroken path, the wire being brought into contact with the forge by evacuating the air in the vacuum and treatment containers through the device 9. Hereby, the melt is sucked up into the processing and vacuum containers to a level determined by the electrode 10's location. The electrode forms one contact part and melts the other contact part in a current circuit, which controls the evacuation of the vacuum and treatment containers by e.g. to influence a solenoid valve connected in an evacuation hose connected to the body 9. The clearance between the wire and the output nozzle 14 determines the thickness of the applied layer.

Ved kjente anordninger pleier de trekkskiver eller munnstykker som tråden passerer når den forlater smeiten og som har samme funksjon som utgangsmunnstykket 14, nemlig å bestemme beleggets tykkelse, lett å bli tilsmusset av forurensninger i smeiten, hvorved ujevnheter i det pålagte skikt oppstår. Ved at behandlingsbeholderen er langstrakt samt under drift er helt fylt med smelte, oppstår ved trådens bevegelse gjennom smeiten kraftige strom-ninger i denne, hvilke hindrer tilsmussing av utgangsmunnstykket. In the case of known devices, the drawing discs or nozzles which the wire passes when it leaves the forge and which have the same function as the exit nozzle 14, namely to determine the thickness of the coating, tend to be easily soiled by impurities in the forge, whereby unevenness in the applied layer occurs. As the treatment container is elongated and is completely filled with melt during operation, strong currents occur in the wire as it moves through the melt, which prevent fouling of the output nozzle.

Hvis på grunn av driftsforstyrrelse eller av annen grunn tråden skulle opphore å mates frem, påvirker en ikke vist automatanord-ning en likeledes ikke vist magnetventil, som setter evakuerings-slangen i forbindelse med den omgivende atmosfæren. Den i vakuum-og behandlingsbeholderen forekommende smelte renner da tilbake til hovedbeholderen, hvorved risiko for at tråden ved langvarig av-brudd skal opplose smeiten,elimineres. If, due to an operational disturbance or for some other reason, the wire should cease to be fed forward, an automatic device, not shown, affects a solenoid valve, also not shown, which puts the evacuation hose in connection with the surrounding atmosphere. The melt occurring in the vacuum and processing container then flows back to the main container, whereby the risk of the wire dissolving the melt in the event of a prolonged interruption is eliminated.

På grunn av at smeiten tilfores behandlingsbeholderen ved hjelp av en vakuumbeholder samt ved at nivåreguleringen skjer ved hjelp av regulering av vakuumet i vakuumbeholderen og ikke ved hjelp av et overlop, forekommer ved drift ingen tilbakerenning av smeiten til hovedbeholderen. Da behandlingsbeholderen videre er relativt liten, omsettes smeiten i denne så fort at ved f. eks. fortinning av kobbertråd noe i smeiten opplost kobber ikke kan påvises. Due to the fact that the melt is fed into the treatment container using a vacuum container and because the level regulation takes place by means of regulating the vacuum in the vacuum container and not by means of an overflow, no backflow of the melt into the main container occurs during operation. As the processing container is also relatively small, the melt is converted in it so quickly that, e.g. tinning of copper wire some dissolved copper in the smelting cannot be detected.

Ved hjelp av ikke viste termostater reguleres varmen fra de elektriske varmeelémenténe 11 slik at smeiten i behandlingsbeholderen holder den for belegningen egnéde temperatur uavhengig av temperaturfluktuasjoner for smeiten i hovedbeholderen. Dette médrorer at den totale mengde av smeltet metall i hovedbeholderen og behandlingsbeholderen kan være betydelig mindre enn i konven-sjonelle anordninger, ved hvilke belegning og metallsmeltirig skjer i samme beholder. By means of thermostats (not shown), the heat from the electric heating elements 11 is regulated so that the melt in the treatment container maintains the temperature suitable for the coating regardless of temperature fluctuations for the melt in the main container. This means that the total amount of molten metal in the main container and the treatment container can be significantly less than in conventional devices, in which coating and metal melting take place in the same container.

Fordelen ved at tråden efter passering av behandlingsbeholderen beveger seg i en horisontal bane er at overflateskiktet på en enkel og effektiv måte bringes til å storkne ved kjoling ved hjelp av vann. The advantage of the thread moving in a horizontal path after passing through the treatment container is that the surface layer is made to solidify in a simple and effective way by cooling with the help of water.
