Koke ya peteroli ya grafitize yongera ireme ry'icyuma mu buryo bwuzuye binyuze mu kunoza imiterere ya karuboni, kugenzura neza imiterere yacyo, kunoza imikorere y'icyuma, no guhaza ibyifuzo by'inganda zigezweho. Uburyo n'ingaruka byihariye ni ibi bikurikira:
I. Kunoza Imiterere ya Karuboni: Gusimbuka mu buryo bwiza kuva ku "Ibinyampeke by'ibihwagari" ukagera ku "Umuceri Utunganyijwe"
Inyongeramusaruro zisanzwe za karuboni (nk'isukari ya calcium) zigaragaza uburyo atome ya karuboni ikora nabi, ifite igipimo cyo kuyinjizamo cya 60% gusa. Mu buryo bunyuranye, isukari ya graphitized petroleum coke, ikorerwa ubushyuhe bwinshi kuri 2800℃, ikora imiterere isanzwe ya graphite isa n' "amakarita yo gukina ashyizwe hamwe." Iyi miterere ituma ishongera vuba mu cyuma gishongeshejwe, igipimo cyo kuyinjizamo kikiyongera kigera kuri 90%. Urugero, iyo ushongesha icyuma gishongesha (GCr15), ingano ya karuboni igomba kugenzurwa neza mu ntera iri hagati ya 1.05% na 1.15%. Gukoresha inyongeramusaruro ya karuboni ya graphitized bitanga igipimo cyo kuyinjizamo gihamye cya 92%, aho ihindagurika ry'ingano ya karuboni ritarenga ± 0.02%, bityo bikarinda kuvunika cyangwa gukomera guke kw'imirongo biterwa no kugabanuka kw'ingano ya karuboni.
II. Amabwiriza y'imiterere myiza: Guhindura "Gahunda y'imirire" y'icyuma cyo mu rwego rwo hejuru
- Ingano nke y'umwanda: Uburyo bwo gukoresha graphitization buhindura sulfure, azote, n'indi myanda mo imyuka ihindagurika, bigabanura ingano ya sulfure ikagera munsi ya 0.05% na azote ikagera munsi ya 0.01%. Urugero, icyuma cya silikoni kidakoresha ikoranabuhanga gikoreshwa mu mazu mashya akoresha ingufu gisaba ingano ya karuboni iri munsi ya 0.005%, bikaba ngombwa ko hakoreshwa inyongeramusaruro za karuboni zifite graphit nyinshi. Mu buryo nk'ubwo, alloys zishingiye kuri nikeli ku byuma bikoresha ingufu za kirimbuzi zigomba kuba zifite ingano ya azote itarenze 0.01%, ibisabwa ko inyongeramusaruro zisanzwe za karuboni zidashobora kuzuza.
- Kugenzura Ibigize Ibikoresho Bihamye: Mu guhindura ingano y'ibiryo n'ibipimo by'imikorere, ingano y'ibintu nka karuboni, sulfur, na azote mu cyuma gishongeshejwe ishobora kugenzurwa neza. Urugero, mu gushonga kw'itanura ry'amashanyarazi, coke ya peteroli yongewemo hamwe n'ibyuma bisigaye n'ibindi bikoresho byo kwishyuza kugira ngo hirindwe ogisijeni ikabije iterwa no kugaburira abantu benshi, bityo hakagenzurwa ko ingano ya karuboni mu bicuruzwa by'ibicuruzwa byujuje ibisabwa.
III. Kunoza Imikorere y'Ibyuma: Kuva ku "Kudahaga" kugeza ku "Kubyinjiza neza"
- Ubwiyongere bw'igipimo cyo kwinjiza karuboni: Igipimo cyo kwinjiza karuboni muri peteroli ya graphitized coke kiri hejuru ya 30% ugereranyije n'inyongera zisanzwe za karuboni, bivuze ko kuri buri jini 10 za karuboni zongewemo, kwinjiza neza karuboni byiyongeraho jini 3. Ibi bigabanya cyane igihombo cya karuboni mu gihe cy'ibikorwa by'icyuma kandi bigabanya ikiguzi cyo gukora.
- Kugabanuka kw'imyuka ihumanya ikirere: Imiterere mike ya sulfure na azote bya graphitized petroleum coke igabanya imyuka ihumanya ikirere ya sulfure dioxyde na azote mu gihe cyo gushongesha, bihuye n'ibisabwa mu kubungabunga ingufu no kugabanya imyuka ihumanya ikirere. Urugero, gukoresha graphitized petroleum coke bishobora kugabanya imyuka ihumanya ikirere ya sulfure oxyde mu bigo by'ibyuma ku kigero kirenga 50%.
IV. Gukemura ibyifuzo by'inganda zigezweho: Kuva ku "Inzu ikomeye y'icyuma" kugera ku "Imbaraga ikomeye y'icyuma"
- Gushyigikira umusaruro w’ibicuruzwa byo mu rwego rwo hejuru: Koke ya peteroli ya grafitize ni igikoresho cy’ingenzi mu gukora icyuma gikomeye cyane cya grey cast, icyuma cya silicon kidakoresha ikoranabuhanga, aloyi zishingiye kuri nikeli, n’ibindi bikoresho by’icyuma byo mu rwego rwo hejuru. Urugero, gukora ibintu "bikomeye" nk'ibice by'amashanyarazi bya turbine y'umuyaga n'imiyoboro y'ingufu za kirimbuzi bishingiye ku buziranenge bwayo bwinshi n'ubushobozi bwayo bwo kwinjiza ibintu byinshi.
- Guteza imbere inganda: Mu gihe inganda z'ibyuma mu Bushinwa zigenda zihinduka zigana ku iterambere rihambaye kandi ritangiza ibidukikije, "gusimbuza" koke ya peteroli ya grafiti iri kwihuta mu gihugu. Ikoreshwa ryayo ntiryongera gusa ireme ry'ibicuruzwa by'ibyuma ahubwo rinateza imbere iterambere ry'ikoranabuhanga mu nganda zose. Urugero, ikigo cy'ibyuma cyagabanije ihindagurika ry'ibipimo bya karuboni kuva kuri ± 0.05% kugeza kuri ± 0.02% hakoreshejwe koke ya peteroli ya grafiti, bituma igipimo cy'ibipimo by'ibicuruzwa cyiyongeraho 15%.
V. Inyigo z'Urugero: Ingaruka "Zikomeye" za Koke ya Peteroli ya Graphitized
- Umusaruro w'Ibyuma Bifite Ingufu: Nyuma yo gukoresha koke ya peteroli ya grafitize, ikigo runaka cyagabanije ihindagurika ry'ingano ya karuboni y'icyuma gifite ingufu kuva kuri ± 0.05% kugera kuri ± 0.02%, cyongera igipimo cy'iyubahirizwa ry'ibicuruzwa ho 15%, kandi kizigama igihombo cya miliyoni icumi z'amayuan mu bisigazwa by'ibicuruzwa buri mwaka.
- Inzu nshya zikoresha moteri zikoresha ingufu: Hakoreshejwe koke ya peteroli ifite graphite nyinshi, ingano ya karuboni mu cyuma cya silikoni kitari ku murongo yahagaze munsi ya 0.005%, bituma moteri ikora neza ku kigero cya 3% kandi yongera urwego rwo kuyitwara ku kigero cya 5%.
- Ingufu za kirimbuzi: Ingano ya azote mu byuma bikozwe muri nikeli yagenzuwe munsi ya 0.01%, bikumira ko ibikoresho byangirika bitewe n’ingano nyinshi ya azote kandi byongera igihe cyo gukora ibikoresho ku myaka 20.
