I-coke ene-calcined ene-specification efanayo ingahluka kakhulu ngentengo kuye ngemboni engezansi, ngoba isizathu esiyinhloko ukuthi izimboni ezahlukene zine "izidingo ze-specification" ezihlukene ngokuphelele kanye "nokuzimisela ukwamukela ama-premium" - ngakho-ke i-coke efanayo ephuma kuhhavini elifanayo ayiyona into efanayo emehlweni amakhasimende ahlukene.
Okokuqala, izidingo ze-trace element kanye nokuqukethwe kwe-sulfur ziqondisa ngqo igebe lentengo. Ama-anode abhakiwe kusengaphambili okusetshenziswa kwe-aluminium anemikhawulo eqinile ku-vanadium, i-silicon, insimbi, nezinye izakhi zokulandelela, kanti i-sulfur kumele ilawulwe ku-3.0% noma ngaphansi. Lolu hlobo lwe-calcined coke "ye-spec-grade" lungathengiswa ngama-yuan angamakhulu amaningana kuya kwangaphezu kwenkulungwane ngethani ngaphezu kwe-coke ejwayelekile. Isibonelo, i-sulfur calcined coke ephakathi nendawo ephezulu ene-sulfur ku-3.0% kanye ne-vanadium engaphansi kuka-400 PPM yayinentengo yemakethe ephakathi kuka-3,100–3,200 yuan ngethani ngoJuni 2025, kuyilapho i-coke ejwayelekile ene-sulfur efanayo engu-3.0% kodwa ingenazo izidingo ze-trace element ithengiswe cishe ngama-yuan angu-2,350 ngethani - igebe elicishe libe ngama-yuan angu-800. I-coke ene-calcium ephansi ene-sulfur iyamangalisa nakakhulu: i-coke eyenziwe nge-Fushun petroleum coke ingafinyelela intengo yangaphambili yefektri engu-5,200–5,400 yuan ngethani, kuyilapho i-coke eyenziwe nge-Jinxi noma i-Jinzhou petroleum coke ithengiswa kuphela ngo-4,400–4,700 yuan ngethani. Imvelaphi yezinto zokusetshenziswa zodwa idala igebe elicishe libe yinkulungwane yama-yuan, futhi uma ubeka imfuneko yesulfur ephansi ngaphansi kuka-0.5%, intengo iphinda kabili ngokoqobo.
Okwesibili, inzuzo yemboni engezansi kanye namandla okuxoxisana kunquma ukuthi bazimisele ukukhokha malini. Izinto ze-anode zebhethri le-lithium-ion kanye nama-electrode e-graphite “anesidingo esiqinile ngaphakathi kwesidingo esiqinile” se-coke ene-sulfur calcined coke - imikhiqizo yabo inenani eliphezulu elengeziwe, ngakho-ke bazimisele ukudonsa amanani angaphezu kwama-yuan angu-5,000 ngethani futhi bazama ngisho nokuphakelwa lapho izinto zokusetshenziswa ziqinile. Ngokuphambene nalokho, abasebenzisi abangezansi njenge-silicon yezimboni kanye nengilazi baphatha i-coke ene-calcined njengento engeyona into ngaphandle kukaphethiloli ojwayelekile noma i-reductant - bakhathalela kuphela intengo ephansi kakhulu futhi bamelana kakhulu nemithombo ebiza kakhulu. Ukucaciswa okufanayo kwe-coke ezandleni zabo kungaba yi-yuan engu-2,000 kuphela. Imboni ye-aluminium ye-electrolytic, naphezu komthamo wayo omkhulu, icindezela amanani okuthenga. NgoJulayi 2025, amanani entengo avela ezitshalweni eziningi ze-aluminium ayesancipha uma kuqhathaniswa noJuni, ecindezela imingcele yabakhiqizi be-coke ene-calcined ekulahlekelweni yi-yuan engu-170-250 ngethani.
Okwesithathu, "inani lokusebenza" le-coke efanayo ezimweni ezahlukene zokusetshenziswa lihlukile ngokuphelele. Isibonelo, lapho i-coke ene-sulfur calcined isetshenziswa kuma-electrode e-graphite, inquma ukuqhutshwa kukagesi kwe-electrode kanye nokumelana nokugqwala, okuthinta ngqo ikhwalithi yensimbi engezansi - amakhasimende awazweli entengo. Kodwa i-coke efanayo esetshenziswa njenge-carburizer imane ithatha indawo yensimbi elahliwe, futhi amakhasimende azwela kakhulu entengo - ngeke akhokhe ngisho nama-yuan angu-200 engeziwe ngethani. Lolu hlobo "lwe-premium yokusebenza" lwenza i-coke efanayo ifanele amanani ahlukene kakhulu ezimbonini ezahlukene.
Okwesine, amamodeli okuthenga kanye nemigomo yokukhokha nakho kukhulisa igebe lentengo. Izinkampani ze-aluminium kanye nezinto ze-anode ze-electrolytic ngokuvamile zinikeza imigomo yesikweletu, kanti ezinye zithwala ingozi yokwehluleka. Abakhiqizi be-coke abane-calcined, ukuze baqoqe izinkokhelo, kufanele bancintisane namakhasimende anesikweletu esihle ngokunikeza amanani aphansi. Engxenyeni yokuqala ka-2025, imboni ye-coke ene-calcium ephansi ye-sulfur ithole isilinganiso sokulahlekelwa yi-yuan engu-200 ngethani, kanti i-sulfur ephakathi nendawo ephezulu ithole isilinganiso sokulahlekelwa yi-yuan engu-190 ngethani. Abakhiqizi basinda ekucindezelweni phakathi komfula ongaphezulu nophansi, benikeza izivumelwano kumakhasimende asezingeni eliphezulu ngenkathi bekhokhisa okwengeziwe kulabo ababuthakathaka - okwandisa kakhulu igebe lentengo yokuthengiselana langempela kuzo zonke imikhakha ehlukene engezansi.
Isifinyezo somusho owodwa: I-coke ekhalisiwe ngokwemvelo “ingumkhiqizo oqediwe kancane.” Intengo yayo yokugcina ayibekwa yi-oven — ichazwa ngokubambisana yimingcele yokucaciswa kwemboni engezansi, inani elengeziwe lomkhiqizo, kanye namandla okuxoxisana. Ithoni efanayo ye-coke eya emgqeni we-graphite electrode bese iya esithandweni sengilazi iyimakethe emibili ehlukene ngokuyisisekelo enezindlela ezimbili zamanani ezihlukene ngokuphelele.
