Uburyo bwo gukora electrode za grafiti zifite imbaraga nyinshi cyane bugomba kuba bwujuje ibisabwa bikomeye kugira ngo habeho ubucucike bwinshi bw'amashanyarazi, ubushyuhe bwinshi, n'imiterere ikomeye ya fiziki. Ibisabwa by'ingenzi byayo bigaragarira mu byiciro bitanu by'ingenzi: guhitamo ibikoresho fatizo, ikoranabuhanga ryo gushushanya, inzira zo gutera, gutunganya grafiti, no gutunganya neza, nk'uko bisobanuwe hano hepfo:
I. Guhitamo ibikoresho fatizo: Kugereranya imiterere yihariye n'ubuziranenge buhanitse
Ibisabwa by'ibanze ku bikoresho fatizo
Ifu ya Needle coke ikora nk'ibikoresho by'ibanze bitewe n'uko ifite graphitization nyinshi hamwe n'ubwiyongere buke bw'ubushyuhe (α₀-₀: 0.5–1.2 × 10⁻⁶/℃), ihura n'ibisabwa bikomeye byo kudahungabana k'ubushyuhe bya electrode z'ingufu nyinshi cyane. Ingano ya electrode z'ingufu nyinshi cyane kurusha iza electrode zisanzwe, zirenga 60% muri electrode z'ingufu nyinshi cyane, mu gihe electrode zisanzwe zikoresha cyane cyane petroli coke.
Gutunganya ibikoresho by'inyongera
Ingufu zihinduka ubushyuhe bwinshi zikoreshwa nk'icyuma gifata ibintu bitewe n'umusaruro wazo mwinshi wa karuboni n'ingano nke y'ihindagurika ry'ikirere, byongera ubucucike bw'amashanyarazi (≥1.68 g/cm³) n'imbaraga za mekanike (imbaraga zo guhindagurika ≥10.5 MPa). Byongeye kandi, coke ya metallurgike yongerwaho kugira ngo ihindure ingano y'uduce dukwirakwira, irusheho kunoza imikorere y'amashanyarazi no kurwanya ubushyuhe.
II. Ikoranabuhanga ryo Gutunganya: Gutunganya Ingano Birenze Ingano
Gutunganya Composite Composite Composite Composite
Uburyo gakondo bwishingikiriza ku bikoresho binini byo gusohora ibikoresho kuri electrode nini, mu gihe electrode zifite ingufu nyinshi zikoresha uburyo bwa kabiri bwo gushushanya:
- Gutunganya by'ibanze: Imashini igabanya ubukana bw'umuraba ikoreshwa mu gukanda ibikoresho bivanze mu biti by'icyatsi kibisi mbere.
- Gutunganya Ibyuma: Ikoranabuhanga ryo gushushanya rikuraho neza inenge z'imbere mu bimera by'icyatsi kibisi, rikongera ubucucike.
Ubu buryo butuma habaho electrode nini (urugero, kugeza kuri mm 1.330) hakoreshejwe ibikoresho bito, bigatuma habaho imbogamizi zisanzwe mu mikorere.
Gukoresha Ibikoresho Bikoresha Ubuhanga Bwo Gusohora Ibikoresho
Imashini yo gusohora electrode ya grafiti ya 60 MN ifite uburyo bwo gushyiraho uburebure bugezweho, gukata ibintu mu buryo buhuje, no gutwara ibintu mu buryo bujyanye n'igihe, irushaho kunoza uburyo bwo gushyiraho uburebure ku kigero cya 55% ugereranije n'uburyo busanzwe, bigatuma umusaruro uhoraho wikora kandi yongera cyane imikorere myiza n'uburyo ibicuruzwa bihora bihagaze.
III. Uburyo bwo gutera: Gutera umuvuduko mwinshi byongera ubucucike n'imbaraga
Guteka inshuro nyinshi
Ama-electrode y'ingufu nyinshi cyane akenera imizunguko 2-3 yo guteramo umuvuduko mwinshi hakoreshejwe ingano yahinduwe mu bushyuhe buringaniye nk'iy'inda, hamwe n'ubwiyongere bw'ibiro bugenzurwa kuri 15%-18%. Buri guteramo umuvuduko bikurikirwa no guteka kwa kabiri (1,200–1,250℃) kugira ngo byuzuze imyenge, bigere ku bucucike bwa nyuma burenga 1.72 g/cm³ n'imbaraga zo gukanda za ≥26.8 MPa.
Uburyo bwihariye bwo kuvura Connector Blanks
Ibice by'umuyoboro bishyirwamo umuvuduko mwinshi (≥2 MPa) n'imizingo myinshi yo guteka kugira ngo bibe bidashobora gukorana na ≤0.15 mΩ, byujuje ibisabwa mu gutwara umuyoboro mwinshi.
IV. Uburyo bwo kuvura Graphitization: Guhindura ubushyuhe bwinshi cyane no kunoza imikorere y'ingufu
Gutunganya Acheson Furnace mu bushyuhe bwinshi
Ubushyuhe bwa Graphitization bugomba kugera kuri ≥2,800℃ kugira ngo atome za karuboni zihindurwe mu buryo butaringaniye bukagira imiterere ya graphite ifite imiterere itatu, bityo zigashobora kugabanya ubushyuhe (≤6.5 μΩ·m) no gutwara ubushyuhe bwinshi. Urugero, hari ikigo cyagabanyije igihe cya graphitization kigera ku mezi atanu kandi kigabanya ikoreshwa ry'ingufu binyuze mu kunoza uburyo bwo gushyushya ibikoresho.
Ikoranabuhanga Rihuriweho Rizigama Ingufu
Ikoranabuhanga rihinduranya ingufu rikoreshwa mu kuzigama inshuro zitandukanye hamwe n’uburyo bwo gukoresha ingufu mu buryo burambye bituma habaho gukurikirana mu buryo nyabwo imizigo y’ibikoresho no guhinduranya uburyo bwo gukora, bigabanya ikoreshwa ry’ingufu ku gipimo cya 30% kandi bigagabanya cyane ikiguzi cy’imikorere.
V. Gutunganya Imashini mu buryo bunonosoye: Igenzura ryimbitse rituma imikorere igenda neza
Ibisabwa ku bijyanye n'ubuziranenge bw'imashini zikoreshwa mu ikoranabuhanga
Ubushobozi bwo kwihanganira uburebure bwa electrode ni ± 1.5%, ubushobozi bwo kwihanganira uburebure bwose ni ± 0.5%, kandi ubushobozi bwo guhuza umugozi bugera ku rwego rwa 4H/4h. Igenzura ry’imiterere y’ikirere rigezweho rigerwaho hakoreshejwe uburyo bwa CNC bwo gupima no gutahura kuri interineti, hirindwa ihindagurika ry’amashanyarazi riterwa no kuba electrode idasanzwe mu gihe cyo gukoresha amashanyarazi mu itanura.
Kunoza Ubwiza bw'Ubuso
Ikoranabuhanga ryo gusohora imyanda rigabanya uburyo bwo gukoresha ibikoresho, rikongera ikoreshwa ry'ibikoresho fatizo. Imiterere y'imirongo ifite imiterere igoramye yorohereza imikorere y'umuyoboro, yongera umusaruro w'ibicuruzwa ku kigero cya 3% kandi yongera imikorere y'umuyoboro ku kigero cya 8%.
