Intsimi yesicelo esiphambili se-coke e-calcined e-China yi-electrolytic aluminium industry, ibalwa ngaphezu kwe-65% yexabiso elipheleleyo le-coke ye-calcined, elandelwa yi-carbon, i-silicon ye-industrial kunye namanye amashishini okunyibilikisa.Ukusetyenziswa kwecoke calcined njengamafutha ikakhulu kwisamente, ukuveliswa kwamandla, iglasi kunye namanye amashishini, kubalwa umlinganiselo omncinci.
Okwangoku, unikezelo lwasekhaya kunye nemfuno ye-coke e-calcined ngokusisiseko iyafana.Nangona kunjalo, ngenxa yokuthunyelwa ngaphandle kwexabiso elikhulu le-coke ye-petroleum ephezulu yesulfure ephantsi, i-coke ye-coke ye-calcined yasekhaya iyonke ayanelanga, kwaye kusafuneka ukuba kungeniswe i-coke ephakathi kunye nephezulu ye-sulfure ye-calcined yokuncedisa.
Ngokwakhiwa kwenani elikhulu leeyunithi zokupheka kwiminyaka yamuva, imveliso ye-coke ye-calcined e-China iya kwandiswa.
Ngokuxhomekeke kumxholo wesulfure, inokuthi ihlulwe ibe yi-coke ephezulu yesulfure (umxholo wesulfure ngaphezu kwe-3%) kunye ne-coke ephantsi yesulfure (umxholo wesulfure ngaphantsi kwe-3%).
I-coke yesulfure ephantsi ingasetyenziswa njenge-anodic paste kunye ne-anode ebhakwe ngaphambili kwisityalo se-aluminium kunye ne-graphite electrode yesityalo sensimbi.
Umgangatho ophezulu we-coke yesulfure ephantsi (umxholo wesulfure ngaphantsi kwe-0.5%) ungasetyenziselwa ukuvelisa i-graphite electrode kunye ne-carbonizing agent.
I-coke yesulfure ephantsi yomgangatho jikelele (umxholo wesulfure ngaphantsi kwe-1.5%) isetyenziswa ngokuqhelekileyo kwimveliso ye-anode ebhakiweyo ngaphambili.
Umgangatho ophantsi we-petroleum coke usetyenziswa ikakhulu ekunyibilikiseni isilicon yeshishini kunye nemveliso ye-anodic paste.
I-high-sulphur coke idla ngokusetyenziswa njengamafutha kwizityalo zesamente nakwimizi-mveliso yamandla.
Isampuli eziqhubekayo nezichanekileyo kunye novavanyo yinxalenye ebalulekileyo yenkqubo yethu yokuvelisa.
I-coke ephezulu yesulfure inokubangela ukuvutha kwegesi ngexesha le-graphitization, okukhokelela ekuqhekekeni kweemveliso zekhabhoni.
Umxholo omlotha ophezulu uya kuthintela i-crystallization yesakhiwo kunye nokuchaphazela ukusebenza kweemveliso zekhabhoni
Inyathelo ngalinye liya kuvavanywa ngononophelo, sifuna ukuyenza ngokuchanekileyo idatha yobhaqo.
Njengenxalenye yenkqubo yethu yomgangatho yonke ipakethe iya kulinganiswa ubuncinci amaxesha ama-3, ukuthintela nakuphi na ukungangqinelani.
Ngaphandle kohlaza calcined coke resistivity iphezulu kakhulu, kufutshane ne-insulator, emva calcining, resistivity yawa kabukhali, inversely ngokulinganayo ukumelana resistivity petroleum coke kunye nobushushu calcined, emva 1300 ℃ calcined petroleum coke resistivity wehla ukuya 500 μm Ω m.okanye njalo.
