Koke ya calcium ifite imiterere imwe ishobora gutandukana cyane bitewe n’inganda ziri mu nzira, kuko impamvu nyamukuru ari uko inganda zitandukanye zifite "ibisabwa ku bipimo" bitandukanye rwose n'"ubushake bwo kwakira amafaranga y'inyongera" - bityo koke imwe iva mu itanura rimwe ntabwo ari ikintu kimwe mu maso y'abakiriya batandukanye.
Ubwa mbere, ibisabwa ku bintu bifatika n'ingano ya sulfure ni byo bituma ibiciro bigabanuka. Anode zitetse mbere zo gukoresha aluminiyumu zifite imipaka ikomeye kuri vanadium, silicon, icyuma, n'ibindi bintu bifatika, kandi sulfure igomba no kugenzurwa kuri 3.0% cyangwa munsi yayo. Ubwo bwoko bwa "spec-grade" coke ya calcium bushobora kugurishwa ku mayuan amagana kugeza ku gihumbi kuri toni ugereranyije na coke isanzwe. Urugero, coke ya sulfure iri hagati na hagati hamwe na sulfure kuri 3.0% na vanadium iri munsi ya 400 PPM yari ifite igiciro mpuzandengo ku isoko cya yuan 3,100–3,200 kuri toni muri Kamena 2025, mu gihe coke isanzwe ifite 3.0% bya sulfure ariko nta bintu bifatika isabwa yagurishijwe ku mayuan agera ku 2,350 kuri toni - icyuho cya yuan hafi 800. Coke ifite calcium nkeya irushaho kuba nziza: coke ikozwe muri Fushun petroleum coke ishobora kugera ku giciro cya yuan 5,200–5,400 ku toni, mu gihe coke ikozwe muri Jinxi cyangwa Jinzhou petroleum coke igurishwa gusa yuan 4,400–4,700 ku toni. Inkomoko y'ibikoresho fatizo byonyine itera icyuho cya yuan hafi igihumbi, kandi iyo ushyize ku giciro cya sulfur kiri munsi ya 0.5%, igiciro kirikuba kabiri mu by'ukuri.
Icya kabiri, inyungu z’inganda zo mu gice cya kabiri n’ubushobozi bwo kugurisha ni byo bigena amafaranga biteguye kwishyura. Ibikoresho bya anode ya bateri ya Lithium-ion na electrode za grafiti bifite "ubukene bukomeye mu busabe bukomeye" kuri coke ifite sulfure nke - ibicuruzwa byayo bifite agaciro kongerewe, bityo biteguye gufata ibiciro biri hejuru ya yuan 5.000 kuri toni ndetse bakanashaka kugurisha iyo ibikoresho fatizo ari bike. Mu buryo bunyuranye, abakoresha bo mu gice cya kabiri nka silicon n’ibirahure bafata coke ifite calcium nk'amavuta asanzwe cyangwa igabanya - bita gusa ku giciro gito cyane kandi birwanya cyane amasoko ahenze. Uburyo bumwe bwo gukoresha coke mu ntoki zabo bushobora kuba bufite agaciro ka yuan 2.000 gusa. Inganda za aluminiyumu zikoresha electrolytic, nubwo zifite ingano nini, zigabanya ibiciro by’amasoko ku isi yose. Muri Nyakanga 2025, ibiciro by’inganda nyinshi za aluminiyumu byari bigikomeza kugabanuka ugereranije na Kamena, bigabanya inyungu z’abakora coke ifite calcium ku gihombo cya yuan 170–250 kuri toni.
Icya gatatu, "agaciro k'imikorere" ya coke imwe mu buryo butandukanye bwo kuyikoresha karatandukanye rwose. Urugero, iyo coke ifite calcium nke ikoreshejwe muri electrode za grafiti, igena uburyo amashanyarazi ya electrode atwaramo n'uburyo irwanya ingese, ibyo bikaba bigira ingaruka ku buryo butaziguye ku bwiza bw'icyuma - abakiriya ntibaba bafite ikibazo ku biciro. Ariko coke imwe ikoreshwa nka carburizer isimbura ibyuma bimwe na bimwe, kandi abakiriya bafite ikibazo ku biciro cyane - ntibazishyura na yuan 200 z'inyongera kuri toni. Ubwo bwoko bwa "premium functional" butuma itsinda rimwe rya coke rigira agaciro gatandukanye cyane mu nganda zitandukanye.
Icya kane, uburyo bwo kugura no kwishyura nabyo byongera icyuho cy’ibiciro. Ibigo bicuruza aluminiyumu n’ibikoresho bya anode muri rusange bitanga amasezerano y’inguzanyo, kandi bimwe bifite ibyago byo kutishyura. Abakora coke ifite calcium, kugira ngo bakusanye amafaranga, bagomba guhatanira abakiriya bafite inguzanyo nziza batanga ibiciro biri hasi. Mu gice cya mbere cya 2025, inganda za coke zifite calcium nke zatakaje igihombo cya yuan 200 kuri toni, naho sulfur iri hagati y’ibiciro byayo yatakaje igihombo cya yuan 190 kuri toni. Abakora baracyari mu gihe cyo hagati y’amazi n’amazi, batanga uburenganzira ku bakiriya beza mu gihe banishyuza byinshi ku bafite intege nke - ibi birushaho kwagura icyuho cy’ibiciro mu buryo bufatika mu nzego zitandukanye zo hasi.
Incamake y'interuro imwe: Koke ya Calcined mu buryo busanzwe ni "igicuruzwa cyarangije gukoreshwa." Igiciro cyayo cya nyuma ntigishyirwaho n'itanura - gihuriweho n'ibipimo by'inganda zo hasi, agaciro k'inyongera ku bicuruzwa, n'imbaraga zo guhanahana. Ingano imwe ya koke ijya mu murongo wa electrode ya grafiti ikajya mu itanura ry'ikirahure ni amasoko abiri atandukanye afite ibiciro bibiri bitandukanye rwose.
