Graphite electrode ikorwa hifashishijwe kokiya ya peteroli hamwe na kokiya y'urushinge hamwe hamwe n'amakara hamwe nk'amakara, binyuze mu ruhererekane rw'ibikorwa birimo kubara, gukanda, kotsa, gutera akabariro, gushushanya no gutunganya imashini.

Graphite electrode nigikoresho cyingenzi cyubushyuhe bwo hejuru bwo gukora itanura ryamashanyarazi. Ingufu z'amashanyarazi zinjizwa mu itanura ry'amashanyarazi binyuze muri electrode ya grafite, n'ubushyuhe bwo hejuru butangwa na arc hagati ya electrode ya elegitoronike n'umuriro bikoreshwa nk'isoko ry'ubushyuhe bwo gushonga amafaranga yo gukora ibyuma. Ibisobanuro biri hagati ya 300 na 800mm ya diametre na 1.8m, 2,1m, 2,4m, na 2.7m z'uburebure.
Igikorwa cyo gukora ni ukubara peteroli ya peteroli kuri 1350 ° C. Ibikomoka kuri kokiya bibarwa byajanjaguwe, hasi hanyuma bikerekanwa kugirango bibe byegeranijwe hamwe nifu isabwa kubumba. Urushinge rwa kokiya na poro bitunganywa hakoreshejwe formulaire ya tekiniki idasanzwe yo kubumba. Kokiya ibarwa ivanze nubunini butandukanye, ibipimo bitandukanye hamwe nigice runaka cya binder asfalt muri knader ukurikije ubushyuhe nigihe.
Nyuma yo gukata, paste ya karubone yoherejwe mubyumba byibikoresho byabugenewe binyuze mumukandara wa convoyeur, hanyuma bigashyirwa mubikoresho byo kubumba. Guhindura plastike bibaho munsi yimbaraga zo hanze, amaherezo bikora electrode yumubiri wicyatsi (cyangwa igicuruzwa kibisi) gifite imiterere, ubunini, ubwinshi nimbaraga. Igicuruzwa kibisi gishyirwa mu itanura ryabugenewe ryabugenewe kugirango habeho ubushyuhe bwo hejuru yubushyuhe kuri 1300 ° C kugirango karubone ikara ryamakara mumubiri wicyatsi kugirango ibe igicuruzwa gifite imbaraga za mashini nyinshi, irwanya ubukana, ituze ryumuriro hamwe n’imiti ihamye.
Kubicuruzwa bya karubone, kotsa nimwe mubikorwa byingenzi mugukora ibicuruzwa bya karubone. Umusemburo wo gutwika ni muremure (iminsi 22-30 yo gutwika bwa mbere, iminsi 5-20 kumunsi wa kabiri ukaranga bitewe n'ubwoko bw'itanura), kandi gukoresha ingufu ni byinshi. Nyuma yibyo, ibikoresho bya karubone bishyirwa mu cyombo cy’umuvuduko, hanyuma asifalt yinjira mu mazi yinjizwa kandi ikinjira mu byobo bya electrode y’ibicuruzwa mu bihe bya 360-400 ° C na 1.5-1.8MPa kugira ngo byongere ubwinshi bw’ijwi. n'imbaraga za mashini yibicuruzwa, no kunoza imikorere no gutwara ibicuruzwa. Amashanyarazi.
Ibicuruzwa byokeje bimaze guterwa, byongeye gutekwa kugirango karubone ikibanza cyinjijwe mu byobo byibicuruzwa byokeje. Noneho shyiramo uburyo bwo gukingira ibicuruzwa bikaranze mu itanura ry’ubushyuhe bwo hejuru kugira ngo ushushe ibicuruzwa bya karuboni hejuru ya 2800 ° C, uhindure karubone ya amorphous turbostratic ya karubone mu buryo butatu buteganijwe bwa grafitike ya kirisiti kugirango utezimbere amashanyarazi, amashanyarazi, n'ubushyuhe bwo kurwanya ibintu bya karubone. Imikorere ihindagurika hamwe nubushakashatsi bwimiti ituma ibintu bya karubone bisiga amavuta kandi bikarwanya kwambara, kandi bigasohora umwanda kugirango ubuziranenge bwibintu bya karubone. Hanyuma, twishingikiriza ku gutema gutunganya kugirango tugere ku bunini busabwa, imiterere, neza, n'ibindi, no gukora umubiri wa electrode wujuje ibisabwa.
Kuberako ingingo ya electrode isaba ubwinshi bwumubiri hamwe nuburwanya buke, inzira yo gutunganya isaba kwibiza bitatu no kurasa bine kugirango byuzuze ibisabwa.
Ibicuruzwa byikigo byacu byujuje ubuziranenge bwa YB / T4088-2015, YB / T4089-2015, YB / T4090-2015. Graphite electrode hamwe ningingo zakozwe bifite ubwinshi bwubwinshi, imbaraga zidasanzwe, imbaraga nke, kurwanya ubushyuhe bwumuriro, kandi Ifite imbaraga zikomeye za okiside kandi iruta ibipimo byigihugu ninganda. Ibicuruzwa byatsinze igenzura ryikigo cyigihugu gishinzwe kugenzura ubuziranenge n’ubugenzuzi.
Ibicuruzwa bifitanye isano
Mu 1985, Datong Lokomotive Works yatahuye ko moteri y’amashanyarazi aricyo cyerekezo cy’iterambere cy’inganda za gari ya moshi n’Ubushinwa mu gihe kiri imbere, maze ishyira ahagaragara igitekerezo cy’ibikorwa by’ibikorwa bya "Nanzhu (Zhuzhou Electric Lokomotive Works) na Datong Lokomotive Work".
Shaoshan Ubwoko bwa lokomoteri yo mu bwoko bwa 3 nigisekuru cyanjye cya kabiri mugihugu cyanjye 6-axe itwara abagenzi hamwe na moteri. Lokomoteri ifata ikiraro-cyuzuye cyuzuye-ikosora kandi ikamenya icyiciro cya thyristor igenzurwa neza na voltage igenga. Lokomoteri ifata sisitemu imwe ya AC 25kV 50Hz ya voltage kandi ifite umuvuduko ntarengwa wa 100km / h.
SS3B yashizwemo na moteri iremereye cyane yamashanyarazi ni moteri ya 12-imizigo yamashanyarazi. Igizwe na lokomoteri ebyiri zisa 6-zihujwe na kuperi hamwe nikirahure. Ibice byombi bifite ibikoresho bya sisitemu yumuriro mwinshi-uhuza, insinga zo kugenzura, hamwe nu kurinda imiyoboro. Imiyoboro hamwe na sisitemu yo kugenzura imiyoboro. Ikinyabiziga cyose kirashobora kugenzurwa icyarimwe kuva cab. Lokomoteri ikoresha sisitemu imwe yumurongo wumurongo wumurongo wa voltage, voltage 25kV, imiyoboro ya AC-DC, kandi umuvuduko ntarengwa wo gukora wa lokomoteri ni 100km / h.
Shaoshan 4 yateje imbere amashanyarazi ni moteri ya 8-axe yimodoka. Lokomoteri igizwe na lokomoteri ebyiri zisa zisa zihujwe na kuperi hamwe nikirahure. Amahugurwa yombi afite ibikoresho bihuza amashanyarazi menshi kuri sisitemu y'amashanyarazi, insinga zo guhuza imiyoboro hamwe na feri yo kugenzura feri yo mu kirere. Ikinyabiziga cyose kirashobora kugenzurwa mugihe kimwe cyabashoferi ba kinyabiziga kimwe. Lokomoteri ebyiri nazo zirashobora gutandukana kandi zigakoreshwa mu bwigenge nka moteri enye.
