Kubera imikorere ya elegitoroniki ya elegitoronike ikora neza harimo n’umuvuduko mwinshi, kurwanya cyane ihungabana ry’umuriro no kwangirika kw’imiti ndetse n’umwanda muke, electrode ya grafite igira uruhare runini mu gukora ibyuma bya EAF mu gihe cy’inganda zigezweho n’ibyuma bya metallurgie isaba kunoza imikorere, kugabanya ibiciro, no kuzamura kuramba.
Graphite Electrode Niki?
GRAPHITE ELECTRODES nibikoresho byiza byogukoresha itanura ryamashanyarazi ya arc hamwe nitanura ryogosha, Byakozwe na coke yinshinge nziza cyane ivanze, ibumbabumbwe, itetse kandi ishushanya kugirango ikore ibicuruzwa byarangiye. Irashobora kwihanganira ubushyuhe bukabije utabanje kumeneka.Ni ubu nigicuruzwa cyonyine kiboneka gifite urwego rwo hejuru rwumuriro wamashanyarazi nubushobozi bwo gukomeza ubushyuhe bukabije cyane butangwa mubidukikije bisaba.
Iyi mikorere igabanya igihombo cyingufu kandi itezimbere uburyo bwose bwo gushonga 'imikorere, bigatuma ingufu nke zikoreshwa nigiciro gito cyumusaruro.
Igishushanyo cya Electrode Ibintu byihariye
GRAPHITE ELECTRODE ninziza yo gukoresha mumatanura ya arc yandi mashanyarazi hamwe nibindi bikorwa byinganda.Imitungo idasanzwe ituma electrode ya grafite ishobora kwihanganira ubushyuhe bwo hejuru bugera kuri 3.000 ° C kugeza hamwe nigitutu mumatara ya arc arc (EAF).
- Ubushyuhe bwo hejuru- Graphite electrode ifite ubushyuhe bwiza bwumuriro, bubafasha kwihanganira ubushyuhe bwinshi nigitutu mugihe cyo gushonga.
- Amashanyarazi make- Kurwanya amashanyarazi make ya electrode ya grafite byorohereza urujya n'uruza rwingufu zamashanyarazi mumatara ya arc.
- Imbaraga Zikomeye- Graphite electrode yagenewe kugira imbaraga za mashini zo guhangana nubushyuhe bwo hejuru hamwe n’umuvuduko mwinshi mu ziko ry’amashanyarazi.
- Kurwanya Imiti Nziza- Graphite ni ibikoresho bidafite imbaraga birwanya imiti myinshi yangiza.Graphite electrode nibyiza gukoreshwa mubidukikije bikaze, aho ibindi bikoresho bishobora kunanirwa kubera ibitero byimiti.
Graphite electrode ntabwo ikoreshwa cyane mumatara ya arc yumuriro gusa, ikoreshwa no mugukora ibyuma bya silicon, fosifore yumuhondo, nibindi byuma bidafite fer, acide, alkalis, nindi miti, ibidukikije byangirika.
Graphite electrode ishyirwa mubyiciro bitatu ukurikije imiterere yumubiri, ibisobanuro hamwe nibikorwa bitandukanye bijyanye nubushobozi bwitanura ryamashanyarazi, umutwaro wamashanyarazi.Ibyiciro bikunze gukoreshwa mubyiciro bya electrode ya grafite ni Ultra-high power (UHP), Power power (HP), na Power Regular (RP).
UHP grafite electrode igaragaramo ubushyuhe bwinshi nubushyuhe buke bwamashanyarazi, bikoreshwa cyane cyane mumashanyarazi ya ultra-high power arc arc (EAF) mugushongesha ibyuma bitunganijwe neza cyangwa ibyuma bidasanzwe. Kuri toni.
HP Graphite Electrode nigikoresho cyiza cyogukoresha itanura ryamashanyarazi ya arc hamwe nitanura rya elegitoronike, ikora nkitwara kugirango yinjize amashanyarazi mu itanura.HP ya grafite electrode isanzwe ikoreshwa mumatara maremare y’amashanyarazi arc (EAF) ifite ubushobozi bwa 400kV / A kuri toni.
RP grafite electrode ikoreshwa cyane mumatara yumuriro wamashanyarazi asanzwe afite ubushobozi bwa 300kV / A kuri toni cyangwa munsi yayo.Icyiciro cya RP gifite ubushyuhe buke bwumuriro nimbaraga za mashini ugereranije na UHP grafite electrode na HP grafite electrode. kubyara umusaruro wo mucyiciro cyo hasi nko gukora ibyuma, gutunganya silikoni, gutunganya fosifore yumuhondo, kubyara inganda zibirahure.
Hamwe nogukenera ingufu zindi zituruka kumashanyarazi, electrode ya grafite nayo igira uruhare runini mugutezimbere selile.
Graphite electrode ifite uburyo bwinshi bwo gukoresha mubikorwa bitandukanye.Bimwe mubikorwa byibanze bya grafite electrode irimo;
Amashanyarazi ya Arc (EAF) mugukora ibyuma
Graphite electrode ikoreshwa mugukora ibyuma bya EAF nikintu cyingenzi cyibyuma bigezweho.Graphite electrode nki kiyobora kugirango itange amashanyarazi mu ziko, nayo itanga ubushyuhe bwo gushonga ibyuma. Inzira ya EAF isaba ubushyuhe bwinshi bwo gushonga ibyuma bishaje, electrode ya grafite irashobora kwihanganira ubushyuhe bwinshi idatakaje ubusugire bwimiterere.Nk'isi ikomeje kwibanda kuburyo burambye kandi bunoze bwo gukora, grafite electrode izakomeza kugira uruhare runini mugukora ibyuma bya EAF.
Itanura rya Ladle (LF)
Itanura rya Ladle (LFs) nibintu byingenzi bigize inzira yo gukora ibyuma. Electrode ya grafite ikoreshwa mu nganda zikozwe mu itanura rya ladle kugirango itange amashanyarazi menshi kandi nubushyuhe bwinshi murwego rwose.Electrode ya grafite ifite ibintu byiza cyane birimo imiyoboro ihanitse, kurwanya ihungabana ryumuriro no kwangirika kwimiti, hamwe nigihe kirekire cyo kubaho, nuburyo bwiza bwo gukoresha itanura rya ladle (LF). Ukoresheje electrode ya grafite, abakoresha itanura rya ladle barashobora kugera kubikorwa byiza, umusaruro no gukoresha neza ibiciro, mugihe ukomeje ubuziranenge bwo hejuru inganda zisaba.
Itanura ryamashanyarazi (SEF)
Graphite electrode ikoreshwa cyane mu itanura ry'amashanyarazi ryarohamye ni ikintu cy'ingenzi mu gukora ibyuma byinshi n'ibikoresho nka fosifore y'umuhondo, silikoni nziza.Graphite electrode itunga ibintu byiza cyane birimo amashanyarazi menshi, guhangana cyane nubushyuhe bwumuriro, hamwe na coefficient nkeya yo kwagura ubushyuhe.Ibi biranga gukora grafite electrode nziza yo gukoreshwa mumatara yumuriro wamashanyarazi, aho ubushyuhe bukabije nibihe bibi nibisanzwe.
Graphite electrode nibintu byingenzi mubikorwa byo gukora ibyuma bya Electric Arc Furnace (EAF). Gukoresha ibyuma bya electrode ya elegitoronike ikoresha igiciro cyingirakamaro mugukora ibyuma. Nigute ushobora guhitamo urwego rukwiye nubunini bwa electrode ya grafite, hari ibintu byinshi ugomba gusuzuma kubisabwa byose.
- Ubwoko bw'icyuma n'amanota
- Imyitozo yo gutwika na ogisijeni
- Urwego rwimbaraga
- Urwego rwubu
- Igishushanyo cy'itanura n'ubushobozi
- Kwishyuza ibikoresho
- Intego ya grafite ya electrode ikoreshwa
Guhitamo grafite ya electrode ikwiye ku itanura ryawe ningirakamaro kugirango ugere ku mikorere myiza, kugabanya gukoresha ingufu, no kugabanya amafaranga yo kubungabunga.
