Tehnički problemTechnical problem
Uobičajena smolasta testa,bilo za izradu spojeva,bilo za izradu samih elemenata obloge,spravi jaju se na relativno visoko j temperaturi,reda veličine od 110 do 140°C.La bi se .spoju iii obloži obezbedila dovoljna kompaktnost i nepropustljivost»potrebno je tc testo nanositi u sukcesivnim slo jevima,maksimalne debljine oc 15 do 20cm,uz nabijanje sa udarima svakog sloja; pomeču nabijača iii tučka montiranog na jednim pneumatskom aparatu.The usual resinous dough, either for the manufacture of joints or for the fabrication of the lining elements themselves, is prepared at a relatively high temperature, ranging in size from 110 to 140 ° C. To provide sufficient compactness and impermeability to the joints or the coats »tc is required apply dough in successive layers, maximum thickness approx. 15 to 20 cm, with compaction with shocks of each layer; between a rammer or a wheel mounted on a single pneumatic apparatus.
Ovaj rad, koji se ranije vršio ručno,bio je težak za radnika koji ga je izvodio,zbog vibracija,toplote i isparenja katrana i dima.This work, previously done manually, was difficult for the worker performing it, due to the vibration, heat and vapor of the tar and smoke.
Vek trajanja jedne elektrolitske čelije za proizvodnju aluminijuma,veoma je zavisan od kvaliteta spojeva izmedju katodnih blokova.The lifetime of an electrolytic cell for aluminum production is highly dependent on the quality of the joints between the cathode blocks.
Utvrdjeno je da ručna nabijanja dovode do neujednačenostl kvaliteta obloge u celi jama,koji zavisi od stručnosti radnika i stepena njegovog zamora.Ručni rad dovodi do neujednačenosti veka trajanja elektrolitskih čelija,koj? direktno zavisi od dobro izvedene obloge.Gotovo u svi® siučajcvima čelije se noraju staviti van pogona zhog infiltracije elektrolita i tečnog aluminijuma kroz ovu oblogu.Manual charges have been found to result in uneven quality of the coating throughout the pit, which depends on the skill of the worker and the degree of fatigue. Manual work leads to an uneven life of the electrolytic cells, which one? It depends directly on the well-formed lining. Almost all cells are forced to put out of operation the electrolyte and liquid aluminum infiltration through this lining.
Tehnički problem,koji se ovi® pronalaskom rešava,jeste ir.ehanizovanje operacije nabijanja ugljeničnih testa, kako radi olakšanja ljudstvu koje to vrši,tako i radi postizanja ujednačenosti i odredjenog kvaliteta spojeva iii same obloge.A technical problem that is solved by this invention is to further optimize the operation of carbon test compacting, both to facilitate the man who performs it and to achieve uniformity and a certain quality of the joints or the lining itself.

Izrael jeni spojevi od ugljeničnog testa imali su dužinu odIsrael's carbon test compounds had a length of
Širi/iu od 40mm i dubinu od 450mm.Width of 40mm and depth of 450mm.
Izrada spoja izvršena je u 4 sukcesivna sloja sa nastavkom 6 dužine 2,55m.The joint was made in 4 successive layers with extension 6, 2.55 m long.
Prvo se stavi jedan sloj ugljeničnog testa višine oko 20 cm, nastavak nabijača se stavi na svoje mesto, i zatim se vrši nabijanje vibracijama i statičkim pritiskom, za vreme od 45 sekundi.One layer of carbon dough about 20 cm in height is first put on, the extender is put in place, and then the vibration and static pressures are compressed for 45 seconds.
Na isti način se postavi, a zatim se nabije drugi, treci i četvrti sloj testa, sve dek nivo spoja ne odgovara višini ugljeničnih blokova koje treba spojiti.The same is done and then the second, third and fourth layers of dough are compacted, all decompression levels not corresponding to the height of the carbon blocks to be joined.
Kada se spoj ohladio uzeti su uzorci na raznim nivoima i na raznim mestima duž spoja.Ustanovijeno je da su gustine (specifične težine) izmedju 1,52 i 1,56, što je znak da je postignuta odlična homogenostWhen the compound cooled, samples were taken at various levels and at different points along the joint. Densities (specific gravities) were found to be between 1.52 and 1.56, indicating that excellent homogeneity was achieved
Stepen nabijanja (odnos izmedju zapremine nabijenog testa i zapremine sirovog testa) je reda veličine 45%, a može da dostigne, pa čak i da prevazidje 50% što je sasvim zadovoljavajuce.The degree of compaction (the ratio between the volume of the compacted dough and the volume of the raw dough) is of the order of 45%, and can reach and even exceed 50% which is quite satisfactory.
Nije primečeno nikakvo zalepijivanje testa za nastavke nabijača Čak i kod pregrejanog testa, niti vračanje testa na gore, s jedne i sa druge Strane nastavka prilikom nabijanja.No sticking of the dough for the filler extensions was observed Even with the overheated dough, nor the dough back up, on one side and the other of the Continuation Drip.
Nakon tri i po godine funkcionisanja ovog niza čelija ustanovljeno je da su kvarovi na elektrolitskim čelijama, koje su bile obložene na gore opisani način, smanjeni. za oko 60%, što čaje nadu da če vek trajanja ovih čelija ifcnositi 6,5 do 7 godina, prema 5 godina, koliki je vek trajanja čelija obloženih po starim ručnim metodama.After three and a half years of operation of this series of cells, it was found that the failures on the electrolytic cells, which were coated as described above, were reduced. by about 60%, which gives hope that the life span of these cells will be 6.5 to 7 years, compared to 5 years, what is the life of the cells coated according to old manual methods.
