Msika wa Graphite Electrode Wogulitsa Zachitsulo: Zowunikira kuchokera ku Ripoti

Graphite electrode (GE) ndi gawo lofunikira popanga zitsulo kudzera munjira yamagetsi yamagetsi yamagetsi (EAF). Pambuyo pazaka zisanu zakuchepa, kufunafuna kwa graphite electrode kunayamba kutuluka mu 2016 ndi kuchuluka kwacitsulo pogwiritsa ntchito njira ya EAF. Kulowera kwazitsulo zamagetsi zomwe zimapangidwa ndi EAF zikuyembekezeka kukhala zokhazikika mtsogolo, chifukwa chakuwonetsetsa kwakukulu kwazachuma chamaukadaulo achilengedwe. Udindo wa China ndi India pakupanga zitsulo za EAF utha kukhala wofunikira m'zaka zikubwerazi popeza kulowererapo kwa zida zamakono za EAF m'maiko onse kumakhala kotsika poyerekeza ndi mayiko otukuka koma adzakwera kwambiri. Izi zikhazikitsa tsogolo labwino pakufunikira kwa ma electrodite azithunzi pazaka zisanu zikubwerazi.

Ma msika ogulitsa amsika ali ndi mphamvu zambiri ndikupanga zinthu zophatikizika (petulole singano) komanso graphite electrode yophatikizidwa ndi kuwonjezereka kosasintha kwa kupanga kwa zitsulo za EAF. Makonda a lifiyamu ya lithiamu-ion pakupanga magalimoto yamagetsi kumawonjezeranso gawo lina. Petroke singano coke ndi chofunikira popangira batiri la lithiamu-ion. Kuphatikiza apo, palibe choloweza m'malo mwa graphite electrode pakupanga zitsulo za EAF, zimapangitsa zinthuzo kukhala zothandiza osati zogulitsa chabe.

Monga mwa Stratview Research, msika wama graphite ma electrode mumakampani azitsulo zapadziko lonse lapansi akuti akuyenera kukula pazaka zisanu zotsatila kufikira US $ 15,3 biliyoni mu 2024. Kuchuluka kwachuma pakupanga zitsulo kudzera mu njira ya EAF, osalowa m'malo mwa EAF graphite electrode pakupanga zitsulo za EAF, ndikugulitsa crunch chifukwa cha zochepa zopanga ndi singano coke ndi graphite electrode ndi zina mwazinthu zomwe zikuthandizira kufunikira kwa ma electrodite a graphite mumakampani azitsulo.

Kutengera mtundu wamalonda, msika umagawika ngati mphamvu zapamwamba kwambiri (UHP), mphamvu yayikulu (HP), komanso mphamvu yokhazikika (RP). UHP ikuyembekezeka kukhalabe yotchuka kwambiri komanso mtundu wamagetsi womwe umakula kwambiri panthawi yanenedweratu. Kukhalitsa kwapamwamba, kukana kwapamwamba kwamafuta, ndi mawonekedwe apamwamba ndizinthu zina zomwe zikuthandizira kufunikira kwa UHP graphite electrode, makamaka pamakampani azitsulo. Onse osewera apadziko lonse lapansi ali makamaka pakupanga ma UHP graphite electrodes.

Kutengera mtundu wofunsira, kupanga zitsulo kukuwongolera msika wama graphite ndipo ikuyembekezeka kukhalabe yolamulira panthawi yaneneratu. Pakhala pakuwonjezereka kopitilira ntchito yopanga zitsulo za EAF padziko lonse lapansi, ndiye woyendetsa wamkulu wofuna chiwonetsero cha graphite electrodes. Mwachitsanzo; ku China, gawo logulitsa zitsulo kudzera mu EAF lidakwera kuchoka pa 6% mu 2016 mpaka 9% mu 2017 (akadali ochepera 46%, kupatula China). Boma la China lakhazikitsa cholinga choti likwaniritse 20% yopanga zitsulo kudzera pa EAF pofika 2020.
