Kwicala lezinto eziluhlaza zezinto ezingafunekiyo ze-electrode, iiPetroChina kunye neefektri zokucoca ze-CNOOC ziyaqhubeka nokuba phantsi koxinzelelo lokuthunyelwa kwe-coke ene-sulfur ephantsi, kwaye amaxabiso entengiselwano yemarike ayaqhubeka nokuhla. Okwangoku, iindleko zezinto eziluhlaza ze-graphite yokwenziwa kunye neentlawulo zokucubungula i-graphitization ziye zehla, kwaye amandla emveliso kwicala lokubonelela akhululwe. Amandla emveliso yeemodeli ezisezantsi neziphakathi ze-graphite yokwenziwa kwimarike aye anda kancinci kancinci, nto leyo ekhokelele ekwehleni kwamaxabiso ezi mveliso. I-graphite yendalo ye-electrode engalunganga yi-39,000-42,000 yuan/ton, i-graphite yokwenziwa yi-50,000-60,000 yuan/ton, kwaye i-mesocarbon microspheres yi-60-75,000 yuan/ton.
Ngokwembono yeendleko, i-needle coke kunye ne-low-sulfur coke, izinto ezikrwada ze-graphite yokwenziwa, zimalunga ne-20%-30% yesakhiwo seendleko, kwaye ixabiso lezinto ezikrwada liye lehla ukusukela kwikota yesithathu.
Ixabiso lemarike le-petroleum coke ene-sulfur ephantsi liye latshintsha kancinci, kwaye ixabiso le-2# eMpuma China naseMzantsi China lehla ngama-yuan angama-200/ton, kwaye ixabiso langoku liyi-4600-5000 yuan/ton. Ngokuphathelele ishishini eliphambili, iHuizhou CNOOC 1#B yehla ngama-yuan angama-600/ton ukuya kuma-yuan angama-4750/ton. Iindawo zokucoca eShandong zehla kancinci, kwaye ukuthunyelwa kwempahla kuye kwavalwa kancinci. Ukwehla kwexabiso le-petroleum coke kuye kwaphucula inzuzo yamashishini e-calcined coke, kwaye ukusebenza kwamashishini e-calcined coke kuye kwahlala kuzinzile. Ixabiso le-slurry yeoyile ene-sulfur ephantsi, izinto eziluhlaza ze-needle coke, liqhubekile nokuhla kwaye okwangoku likwi-5,200-5,220 yuan/ton. Ezinye iinkampani ze-needle coke ezisekelwe kwioyile ziye zamisa okwethutyana iiyunithi zemveliso ye-coke, ukunikezelwa kwe-needle coke iyonke kwanele, iinkampani ezisekelwe kumalahle ziyaqhubeka nokulahlekelwa, kwaye ixesha lokuqala lisaza kugqitywa.
Iindleko zokucubungula i-graphitization zifikelele phantse kwi-50%. Kwikota yesithathu, ngenxa yokukhululwa kwamandla emveliso kwicala lokubonelela, umsantsa wemarike wancipha kancinci kancinci, kwaye iifizi zokucubungula zaqala ukwehla.
Ngokwembono yobonelelo, ikota yesithathu yaqala ukungena kwixesha lokukhula okukhulu kwimveliso ye-electrode engalunganga. Iiprojekthi zokuqala zemveliso ye-electrode engalunganga zafikelela kancinci kumandla emveliso kwaye iiprojekthi ezintsha zakhutshwa ngamandla. Ubonelelo lwemarike lwanda ngokukhawuleza.
Nangona kunjalo, umjikelo wemveliso yegrafiti yokwenziwa inde, kwaye ixabiso le-anode kunye ne-graphitization liye laxoxwa ngazo kwiikota ezininzi kulo nyaka. Kwikota yesithathu, ifektri ye-anode kunye ne-downstream zikwinqanaba lomdlalo wexabiso. Nangona ixabiso lemveliso liye lancipha, akuthethi ukuba ixabiso liye lehla kakhulu.
Kwikota yesine, ingakumbi ukususela ngoNovemba, iifektri zebhetri bezibambe imisebenzi emininzi yokugcina, kwaye imfuno yee-anode iye yancipha; kwaye ngokubhekiselele ekunikezelweni, ukongeza kumandla amatsha emveliso yabavelisi be-anode bendabuko abakhutshwa kancinci kancinci kulo nyaka, kukwakho neefektri ezincinci okanye ezintsha ze-anode ezongeze amandla amatsha kulo nyaka. Ngokukhutshwa kwamandla emveliso, amandla e-electrode angalunganga kwiimodeli ezisezantsi neziphakathi kwimarike aya ngokugqithisileyo kancinci kancinci; ixabiso le-end-coke kunye neendleko ze-graphitization liye lehla, nto leyo ekhokelele ekwehleni okubanzi kwexabiso leemveliso ze-electrode ezisezantsi neziphakathi.
Okwangoku, ezinye iimveliso ezikumgangatho ophantsi nezikumgangatho ophakathi ezisetyenziswa ngokubanzi zisanciphisa amaxabiso, ngelixa ezinye iimveliso ezikumgangatho ophezulu ezineenzuzo zobugcisa ezinamandla ezivela kubavelisi abakhulu azikhawulezi zigqithise okanye zitshintshwe, kwaye amaxabiso aya kuhlala ezinzile kwixesha elifutshane.
Umthamo wemveliso oqhelekileyo we-electrode engalunganga ungaphezulu kancinci, kodwa ngenxa yempembelelo yemali, itekhnoloji, kunye nomjikelo ongezantsi, amanye amashishini e-electrode engalunganga alibazise ixesha lemveliso.
Xa sijonga imakethi ye-electrode embi iyonke, ngenxa yempembelelo yomgaqo-nkqubo wenkxaso-mali, ukukhula kwemakethi yezithuthi zamandla amatsha kunqongophele, kwaye uninzi lweefektri zeebhetri zisebenzisa kakhulu izinto ezikhoyo. Ikwahambelana nomhla wokutyikitywa kwekhontrakthi kunyaka olandelayo.
Ukwenziwa kweGraphitization: Iingxaki zezothutho kunye nezothutho ezibangelwe yimpembelelo yobhubhane e-Inner Mongolia nakwezinye iindawo ziye zancitshiswa, kodwa ngenxa yempembelelo yamandla emveliso kunye nezinto eziluhlaza, ixabiso lokwenziwa kweGraphitization kwi-OEM processing lisaqhubeka nokuhla, kwaye inkxaso ebiza kakhulu yezixhobo ze-anode zegraphite ezenziweyo iyaqhubeka nokuba buthathaka. Okwangoku, ukuze kulawulwe iindleko kwaye kuncitshiswe umngcipheko wokuphazamiseka kobonelelo, iifektri ezininzi ze-anode zikhetha ukubeka uthotho olupheleleyo lwemizi-mveliso ukuze kuphuculwe ukukhuphisana kwazo. Okwangoku, ixabiso eliqhelekileyo le-multi-graphitization yi-17,000-19,000 yuan/ton. Izixhobo zezixhobo zokubamba kunye nee-crucibles zininzi kwaye amaxabiso azinzile.
