Description
Fremgangsmåte til å forbinde kullblokker i kontinuerlige elektroder for Method of connecting coal blocks in continuous electrodes for
elektroovner, særlig for smelteelektrolyse. electric furnaces, especially for melting electrolysis.
For kontinuerlig arbeide med elek-triske ovner som drives med kullelektro-der, f. eks. for fremstilling av aluminium For continuous work with electric furnaces operated with coal electrodes, e.g. for the production of aluminium
ved smeltebadeelektrolyse, er det kjent å by melt bath electrolysis, it is known to
anvende selvbrennende kontinuerlige elektroder. Det er videre kjent å arbeide med use self-igniting continuous electrodes. It is also known to work with
faste, på forhånd brente elektroder på den fixed, pre-burned electrodes on it
måte at det settes nye elektrodeblokker på way that new electrode blocks are inserted
elektroder som etter hvert brenner bort. electrodes that eventually burn away.
Herunder er det særlig viktig at det mellom de enkelte elektrodeblokker fås en Here it is particularly important that between the individual electrode blocks there is a
elektrisk godt ledende forbindelse. Dette electrically well-conducting connection. This
har man hittil søkt å oppnå derved at man has so far sought to achieve thereby that one
forbandt de enkelte blokker ved hjelp av connected the individual blocks using
spesielle utformninger, f. eks. gjengede deler eller svaleformige spor og lister. special designs, e.g. threaded parts or dovetail grooves and moldings.
Bortsett fra den omstendelige hånd-tering som slike forbindelser krever, får Apart from the cumbersome handling that such connections require, get
man heller ikke noen sikker strømover-gang da de virksomme kontaktflater mellom blokkene bare blir små. Man har derfor også allerede foreslått å innføre mellom blokkene, før sammenføyningen, et nor is there any safe current transition as the effective contact surfaces between the blocks are only small. It has therefore also already been proposed to introduce between the blocks, before the joining, a
tynt lag av flytende bindemiddel, f. eks. en thin layer of liquid binder, e.g. one
tynn blanding av bek og bekkoks, som thin mixture of pitch and stream coke, which
skal utfylle mellomrommene som befinner must fill in the spaces that are located
seg mellom de direkte kontaktflater på between the direct contact surfaces of
blokkene, og som etter å være blitt for-kokset skal delta i strømledningen. Det har the blocks, and which, after being pre-coked, will participate in the power line. It has
imidlertid vist seg at dette tynne binde-middellag krymper ved forkoksingen og however, it has been shown that this thin binder layer shrinks during coking and
går i stykker og derfor ikke oppfyller sitt breaks down and therefore does not fulfill its purpose
formål. purpose.
Det er i patent nr. 89.839 beskrevet It is described in patent no. 89,839
en fremgangsmåte hvor de enkelte på forhånd brente elektrodeblokker blir forbun-det med hinannen på den måte at det mel- a method where the individual pre-fired electrode blocks are connected to each other in such a way that the
lom blokkene anbringes et mellomlag av ubrent elektrodemasse som har en slik minste tykkelse at det sikres en fast forbindelse og en sikker strømovergang mellom blokkene etter forkoksingen. For å oppnå dette skal forbindelseslaget ha en tykkelse på minst 5 mm, fortrinnsvis 10— 15 mm. Konsistensen av forbindelsesmas-sen skal være slik at den under eventuell svak oppvarming eller tilsetning av opp-løsningsmiddel riktignok blir plastisk og kan påføres godt og tett, men at den ikke flyter ut til siden som følge av trykket av den ovenpå liggende elektrodeblokk ved temperatur under forkoksingstemperatu-ren. Massen skal altså virke på lignende måte som mørtel ved muring av teglsten, hvilket lett kan oppnås ved riktig valg av korningen av de faste bestanddeler, (koks) og av bindemidlet (f. eks. bek eller jord-oljeprodukter), idet bindemiddelmassen består av 25—35 pst. bindemiddel og 75— 65 pst. fast stoff, idet 50—75 pst. av det an intermediate layer of unburnt electrode mass is placed between the blocks, which has such a minimum thickness that a firm connection and a safe current transition between the blocks is ensured after coking. To achieve this, the connecting layer must have a thickness of at least 5 mm, preferably 10-15 mm. The consistency of the compound must be such that, under possible slight heating or the addition of solvent, it does indeed become plastic and can be applied well and tightly, but that it does not flow to the side as a result of the pressure of the electrode block lying on top at a temperature below the coking temperature. The mass should therefore act in a similar way to mortar when laying bricks, which can easily be achieved by correctly choosing the grain of the solid components (coke) and of the binder (e.g. pitch or petroleum products), as the binder mass consists of 25-35 per cent binder and 75-65 per cent solids, with 50-75 per cent of that
faste stoffet foreligger i en kornstørrelse på 0—0,5 mm og resten foreligger i en kornstørrelse på ca. 0,5—3 mm. the solid substance is present in a grain size of 0-0.5 mm and the rest is present in a grain size of approx. 0.5-3 mm.
Ifølge oppfinnelsen anvendes mellom-laget eller kittlaget, som er fremstilt ved hjelp av vanlige formgivingsfremgangsmå-ter for plastiske eller støpbare masser, uav-hengig av anvendelsestiden og anvendelsesstedet for kullblokkene. De tekniske fremskritt som oppnås ifølge oppfinnelsen beror på den omstendighet at kittet som anvendes til forbindelse av elektrodeblokkene er absolutt fast og hårdt ved værel-sestemperatur, som f. eks. segllakk. Kittet behøver ikke å bringes til anvendelse i flytende form, som oppnås ved oppvarming According to the invention, the intermediate layer or putty layer is used, which is produced by means of normal shaping methods for plastic or castable masses, regardless of the time of use and the place of use of the coal blocks. The technical advances achieved according to the invention are due to the fact that the putty used to connect the electrode blocks is absolutely firm and hard at room temperature, as e.g. sealing wax. The putty does not need to be used in liquid form, which is obtained by heating
til ca. 130—200° C, men kan i fast form to approx. 130—200° C, but can be in solid form

The putty layer can therefore also be produced locally and/or in time separated from the place of use, resp. the time of application, as a special form body. These

metall-tråder. Det er hensiktsmessig å til-passe formlegemene geometrisk til elektrode-kittf laten. Kittlag-formlegemene metal threads. It is expedient to adapt the shaped bodies geometrically to the electrode putty surface. The putty layer shapes

En annen variant består deri at elektrodeblokkene fremstilles — i likhet med Another variant consists in the fact that the electrode blocks are produced - similar to
