I-coke ene-calcined efanayo inokwahluka kakhulu ngexabiso ngokuxhomekeke kushishino olusezantsi, kuba isizathu esiphambili kukuba amashishini ahlukeneyo aneemfuno ezahlukeneyo "zeenkcukacha" kunye "nokuzimisela ukufunxa iiprimiyamu" - ngoko ke i-coke efanayo ephuma kwi-oven enye ayisiyonto ifanayo emehlweni abathengi abahlukeneyo.
Okokuqala, iimfuno ze-trace element kunye nomxholo we-sulfur ziqhuba ngokuthe ngqo umsantsa wamaxabiso. Ii-anode ezibhakiweyo kwangaphambili zokusetyenziswa kwe-aluminium zinemida engqongqo kwi-vanadium, i-silicon, i-iron, kunye nezinye izinto ezincinci, kwaye i-sulfur kufuneka ilawulwe kwi-3.0% okanye nangaphantsi. Olu hlobo lwe-"spec-grade" coke calcined coke lunokuthengiswa ngamakhulu aliqela ukuya ngaphezulu kwewaka le-yuan ngetoni ngaphezu kwe-generic coke. Umzekelo, i-sulfur ephakathi-phezulu calcined coke ene-sulfur kwi-3.0% kunye ne-vanadium ngaphantsi kwe-400 PPM yayinexabiso eliphakathi lemarike le-3,100–3,200 yuan ngetoni ngoJuni 2025, ngelixa i-generic coke ene-3.0% sulfur kodwa ingenazo iimfuno ze-trace element ithengiswa malunga ne-2,350 yuan ngetoni - umsantsa ophantse ube yi-800 yuan. I-coke ene-sulfur calcined esezantsi iyamangalisa nangakumbi: i-coke eyenziwe nge-Fushun petroleum coke inokufikelela kwixabiso langaphambili le-5,200–5,400 yuan ngetoni, ngelixa i-coke eyenziwe nge-Jinxi okanye i-Jinzhou petroleum coke ithengiswa kuphela nge-4,400–4,700 yuan ngetoni. Imvelaphi yezinto eziluhlaza yodwa idala umsantsa ophantse ube liwaka le-yuan, kwaye xa ubeka imfuneko yesalfure esezantsi ngaphantsi kwe-0.5%, ixabiso liphinda kabini ngokoqobo.
Okwesibini, inzuzo yeshishini elisezantsi kunye namandla okuxoxisana agqiba ukuba bazimisele ukuhlawula malini. Izixhobo ze-anode zebhetri ye-lithium-ion kunye nee-electrode ze-graphite "zinemfuno eqinileyo ngaphakathi kwemfuno eqinileyo" ye-coke ene-sulfur ephantsi - iimveliso zabo zinexabiso eliphezulu elongezelelekileyo, ngoko ke bazimisele ukufunxa amaxabiso angaphezu kwama-5,000 yuan ngetoni kwaye bade bafune ukubonelela xa izinto eziluhlaza zixinene. Ngokwahlukileyo koko, abasebenzisi abasezantsi njenge-silicon yemizi-mveliso kunye neglasi baphatha i-coke ene-calcined njengento engeyonto ngaphandle kwepetroli eqhelekileyo okanye i-reductant - bakhathalele kuphela ixabiso eliphantsi kwaye bamelana kakhulu nemithombo ebiza kakhulu. Inkcazo efanayo ye-coke ezandleni zabo inokuba yi-yuan engama-2,000 kuphela. Ishishini le-aluminium ye-electrolytic, nangona linomthamo omkhulu, linciphisa amaxabiso okuthenga. NgoJulayi 2025, amaxabiso ethenda avela kwizityalo ezininzi ze-aluminium ayesasihla xa kuthelekiswa noJuni, ecinezela imida yabavelisi be-coke ene-calcined ukuya ekulahlekelweni yi-170–250 yuan ngetoni.
Okwesithathu, "ixabiso lokusebenza" le-coke efanayo kwiimeko ezahlukeneyo zokusetyenziswa lahlukile ngokupheleleyo. Umzekelo, xa i-coke ene-sulfur calcined isetyenziswa kwi-graphite electrodes, imisela umbane we-electrode kunye nokumelana nokugqwala, okuchaphazela ngokuthe ngqo umgangatho wentsimbi esezantsi - abathengi abacingi ngexabiso. Kodwa i-coke efanayo esetyenziswa njenge-carburizer ithatha indawo yentsimbi elahliweyo, kwaye abathengi bacinga ngexabiso kakhulu - abayi kuhlawula ne-200 yuan eyongezelelweyo ngetoni. Olu hlobo "lweprimiyamu yokusebenza" lwenza ibhetshi efanayo ye-coke ixabiseke kakhulu kwiimveliso ezahlukeneyo.
Okwesine, iimodeli zokuthenga kunye nemiqathango yokuhlawula nazo ziyawandisa umsantsa wamaxabiso. Iinkampani ze-aluminium kunye nezinto ze-anode ze-electrolytic zihlala zibonelela ngemiqathango yetyala, kwaye ezinye zinomngcipheko wokusilela. Abavelisi be-coke abane-calcined, ukuze baqokelele iintlawulo, kufuneka bakhuphisane nabathengi abanekhredithi elungileyo ngokubonelela ngamaxabiso aphantsi. Kwisiqingatha sokuqala sowama-2025, ishishini le-coke eline-sulfur calcined eliphantsi lifumene umyinge welahleko ye-200 yuan ngetoni, kwaye i-sulfur ephakathi nephezulu ifumene umyinge welahleko ye-190 yuan ngetoni. Abavelisi bayasinda kuxinzelelo oluphakathi komlambo nomlambo, benika abathengi abasemgangathweni ngelixa behlawulisa ngaphezulu kwabo babuthathaka - nto leyo eyandisa ngakumbi umsantsa wamaxabiso entengiselwano kumacandelo ahlukeneyo asezantsi.
Isishwankathelo sesivakalisi esinye: I-coke e-calcined ngokwemvelo "yimveliso egqityiweyo kancinci." Ixabiso layo lokugqibela alimiselwanga yi-oven - ichazwa ngokudibeneyo yimida yeenkcukacha zeshishini elisezantsi, ixabiso elongezelelweyo lemveliso, kunye namandla okuxoxisana. Itoni efanayo ye-coke esiya kumgca we-graphite electrode kwaye isiya kumlilo weglasi ziindawo ezimbini ezahlukeneyo ngokusisiseko ezineendlela ezimbini ezahlukeneyo zamaxabiso.
