Description
Fremgangsmåte for fremstilling av store blokker av aluminium eller aluminiumlegering, som er bestemt for igjen å smeltes inn. Process for the production of large blocks of aluminum or aluminum alloy, which are intended to be remelted.
Det hyttealuminium som fremstilles i The cabin aluminum that is manufactured in
aluminiumelektrolyseovn blir i alminnelig-het støpt i barrer, når det senere skal smeltes inn igjen, f. eks. for fremstilling av le-geringer, som så forarbeides til valseblokker aluminum electrolysis furnace is generally cast in ingots, when it is later remelted, e.g. for the production of alloys, which are then processed into rolling blocks
eller pressbolter. Da ovnsenhetene og for-arbeidningsmaskinene stadig blir større, er or compression bolts. Since the furnace units and pre-processing machines are getting bigger and bigger, is
det allerede i mange bedrifter blitt almin-nelig ikke lenger å støpe aluminiumet i it has already become common in many companies to no longer cast aluminum in it
forholdsvis små barrer, men i større blokker på f. eks. 250—500 kg som ikke lenger relatively small ingots, but in larger blocks of e.g. 250-500 kg which no longer
kan løftes med hånden og som løftes opp can be lifted by hand and which is lifted up
på vogner eller transporteres til omsmelte-ovnene f. eks. ved hjelp av tenger som er on wagons or transported to the remelting furnaces, e.g. using forceps that are
hengt opp i løpekatter. hung up in running cats.
Oppfinnelsen angår nå fremstillingen The invention now concerns the manufacture
av store blokker som veier, f. eks. 250—500 of large blocks that weigh, e.g. 250—500
kg, som er bestemt for igjen å smeltes om, kg, which is destined to be remelted again,
av aluminium eller aluminiumlegeringer, of aluminum or aluminum alloys,
med i det vesentlige rettvinklet tverrsnitt. with an essentially right-angled cross-section.
Det særegne ved oppfinnelsen ligger i The peculiarity of the invention lies in
at blokkene fremstilles ved kontinuerlig that the blocks are produced by continuous
støping i en kokille som er forsynt med casting in a mold which is provided with
fremspring ved ytterkantene på de to bredsider av kokillen hvorved blokkene på de protrusions at the outer edges on the two broad sides of the mold whereby the blocks on the
tilsvarende sider får kantuttagninger som corresponding sides get edge cuts that
strekker seg i lengderetningen og som danner angrepsflater for stablevogn-gafler. extends in the longitudinal direction and which form attack surfaces for stacker forks.
Det er tidligere fremstillet slike blokker ved enkel blokkstøping. Fremstillingen Such blocks have previously been produced by simple block casting. The production
ved kontinuerlig støping byr den vesentlige in continuous casting it offers the essential
fordel at de blokker som oppnås er mer advantage that the blocks obtained are more
kompakte og spesielt har en bedre overflate compact and especially have a better surface
ved kantene. Overflaten vil praktisk talt at the edges. The surface will practically
ikke bli dårligere ved lengre lagring, ved do not deteriorate with longer storage, wood
opptagelse av vann eller forurensninger og ved oksydering. Ved omsmeltingen blir det mindre skrap ved avfall og avbrann. absorption of water or pollutants and by oxidation. During the remelting, there is less scrap from waste and incineration.
Blokker som er fremstillet ved frem-gangsmåten i henhold til oppfinnelsen blir hensiktsmessig støpt fra en blandeovn som beskikkes med metal fra flere aluminiums-fremstillingsovner og derfor har en enhet-lig sammensetning. Fortrinnsvis er metal-let i blandeovnen allerede blitt raffinert, slik at det ikke lenger er nødvendig å gjen-nomføre en raffinering ved den videre be-arbeiding, f. eks. ved oppblanding med le-geringskomponenter. Blocks produced by the method according to the invention are suitably cast from a mixing furnace which is coated with metal from several aluminum production furnaces and therefore has a uniform composition. Preferably, the metal in the mixing furnace has already been refined, so that it is no longer necessary to carry out a refinement during the further processing, e.g. by mixing with alloy components.
Tegningen viser et perspektivriss av en The drawing shows a perspective view of one
slik blokk i en eksempelvis utforming. Ut-tagningene for stablevogn-gaflen er beteg-net 1. Blokken blir støpt i en strengstøpe-kokille hvis indre tverrsnitt tilsvarer ende-flaten 2. En kort kokille er særlig egnet for dette formål. Blokken kan støpes med vil-kårlig lengde, hvoretter den deles opp i de ønskede lengder ved saging eller på annen måte. Den kan imidlertid også støpes i den lengde som ønskes. such a block in an exemplary design. The recesses for the stacker fork are designated 1. The block is cast in a string casting mold whose internal cross-section corresponds to the end surface 2. A short mold is particularly suitable for this purpose. The block can be cast to any length, after which it is divided into the desired lengths by sawing or in some other way. However, it can also be molded to the desired length.
