1. IMIKORESHEREZO
Kokiya (hafi 75-80% mubirimo)
Kokiya ya peteroli
Kokiya ya peteroli nigikoresho cyingenzi cyane, kandi ikorwa muburyo butandukanye, kuva kokisi ya inshinge ya anisotropique cyane kugeza kokiya isotropique. Urushinge rwa anisotropique cyane, kubera imiterere yarwo, ni ntangarugero mu gukora electrode ikora cyane ikoreshwa mu ziko ry’amashanyarazi, aho hakenewe ingufu nyinshi cyane z’amashanyarazi, ubukanishi n’ubushyuhe bwo gutwara ibintu. Kokiya ya peteroli ikorwa gusa nubukererwe bwa kokiya yatinze, nuburyo bworoheje bwa karubone buhoro buhoro bwibisigazwa bya peteroli.
Urushinge rwa kokiya nijambo rikoreshwa muburyo bwihariye bwa kokiya hamwe nubushushanyo buhanitse cyane buturuka ku cyerekezo gikomeye cyerekeranye nicyerekezo cya turbostratic layer layer nuburyo bwihariye bwibinyampeke.
Binders (hafi 20-25% mubirimo)
Ikara ry'amakara
Ibikoresho byo guhuza bikoreshwa muguhuza ibice bikomeye kuri buriwese. Ubushobozi bwabo bwo guhanagura cyane rero buhindura kuvanga muburyo bwa plastike kugirango bibumbwe cyangwa bisohoke.
Ikara ry'amakara ni ifumbire mvaruganda kandi ifite imiterere itandukanye. Bitewe numubare munini wimpeta za benzene zasimbujwe kandi zegeranye, zimaze kugira imiterere yihariye ya hexagonal lattice imiterere ya grafite, bityo ikorohereza gushiraho imiterere ya grafitike itunganijwe neza mugihe cyo gushushanya. Ikibanza kigaragaza ko ari cyiza cyane. Nibisigisigi bya distillation yumuriro wamakara.
2. Kuvangavanga no GUSOHORA
Kokiya yasya ivanze nigitereko cyamakara hamwe ninyongeramusaruro kugirango ikore paste imwe. Ibi bizanwa muri silinderi yo gukuramo. Mu ntambwe yambere umwuka ugomba gukurwaho mukwitegura. Kurenza intambwe nyayo yo gukuramo ikurikira aho imvange isohorwa kugirango ikore electrode ya diameter yifuzwa n'uburebure. Kugirango ushoboze kuvanga cyane cyane inzira yo gukuramo (reba ishusho iburyo) imvange igomba kuba igaragara. Ibi bigerwaho nukubika ubushyuhe bwo hejuru bwa hafi. 120 ° C (ukurikije ikibuga) mugihe cyose cyicyatsi kibisi. Ubu buryo bwibanze bufite ishusho ya silindrike buzwi nka "icyatsi kibisi".
3. GUKORA
Ubwoko bubiri bw'itanura ryo guteka burimo gukoreshwa:
Hano inkoni zasohotse zishyirwa muri silindrike idafite ibyuma (saggers). Kugira ngo wirinde guhindura imikorere ya electrode mugihe cyo gushyushya, imashini nayo yuzuyemo igipfundikizo cyumucanga. Amashanyarazi apakirwa kuri gari ya moshi (munsi yimodoka) hanyuma akazunguruka muri gaze karemano - itanura ryaka.
Itanura ry'impeta
Hano electrode ishyirwa mumabuye yihishe munsi yububiko. Iyi cavit ni igice cya sisitemu yimpeta zirenga 10. Ibyumba bihujwe hamwe na sisitemu ishyushye yo kuzenguruka ikirere kugirango ibike ingufu. Icyuho kiri hagati ya electrode nacyo cyuzuyemo umucanga kugirango wirinde guhinduka. Mugihe cyo guteka, aho ikibanza kirimo karubone, ubushyuhe bugomba kugenzurwa neza kuko kubushyuhe bugera kuri 800 ° C gazi yihuta ishobora gutera gucika electrode.
Muri iki cyiciro electrode ifite ubucucike hafi 1.55 - 1,60 kg / dm3.
4. GUSHYIRA MU BIKORWA
Electrode yatetse yinjizwemo ikibanza kidasanzwe (ikibanza cyamazi kuri 200 ° C) kugirango kibahe ubucucike buri hejuru, imbaraga za mashini, hamwe n’umuriro w'amashanyarazi bazakenera guhangana n’imikorere ikaze iri mu itanura.
5. KUGARUKA
Inzinguzingo ya kabiri yo guteka, cyangwa "kwisubiraho," irasabwa kugirango karubone yinjire mu kibanza no kwirukana ibirindiro byose bisigaye. Ubushyuhe bwa reake bugera kuri 750 ° C. Muri iki cyiciro electrode irashobora kugera ku bucucike hafi 1,67 - 1,74 kg / dm3.
6. GUKORESHWA
Acheson Furnace
Intambwe yanyuma mubikorwa bya grafite ni uguhindura karubone yatetse kuri grafite, bita gushushanya. Mugihe cyo gushushanya, ibyinshi cyangwa bike byateganijwe mbere ya karubone (karubone ya turbostratique) ihindurwa muburyo butatu bwa grafite.
Electrode ipakiye mu ziko ryamashanyarazi ikikijwe nuduce twa karubone kugirango ikore misa ikomeye. Umuyagankuba unyuzwa mu ziko, uzamura ubushyuhe bugera kuri 3000 ° C. Ubu buryo busanzwe bugerwaho hifashishijwe ACHESON FURNACE cyangwa LENGTHWISE FURNACE (LWG).
Hamwe n'itanura rya Acheson electrode ishushanywa hakoreshejwe inzira, mugihe mu itanura rya LWG inkingi yose yashushanyije icyarimwe.
7. GUKORA
Graphite electrode (nyuma yo gukonjesha) ikozwe mubipimo nyabyo no kwihanganira. Iki cyiciro gishobora kandi kubamo gutunganya no guhuza impera (socket) ya electrode hamwe na papine ya grafite ya pine (nipple) ihuza sisitemu.
