Bitewe n'igiciro kinini cya electrode za grafiti n'ubukene bukabije bw'ibikenewe, imyumvire ku isoko rya electrode za grafiti yahindutse vuba aha. Ku ruhande rumwe, isoko riherutse gutanga umusaruro n'ubukene biracyagaragaza imiterere y'ubuziranenge, kandi amwe mu masosiyete ya electrode za grafiti aracyafite icyifuzo gikomeye cyo kohereza no kurundanya imitungo; Ku rundi ruhande, ikiguzi cy'umusaruro wa electrode za grafiti kiri hejuru, kandi inyungu muri rusange ku isoko ntabwo ihagije. Kugira ngo hirindwe ihindagurika ry'ibiciro, amasosiyete ya electrode ya Graphite nayo yiteguye kugabanya ibiciro.
Ku ya 6 Nzeri 2021, ibiciro by’ingenzi bya electrode za grafiti mu Bushinwa bifite umurambararo wa mm 300-600: ingufu zisanzwe 15000-18000 yuan/toni; ingufu zikomeye 17000-20500 yuan/toni; ingufu zikomeye 17000-25000 yuan/toni; ingufu zikomeye 700mm graphite Electrode 27000-30000 yuan/toni. Igiciro mpuzandengo ku isoko cya electrode za grafiti mu Bushinwa cyari yuan 20,286/toni, igabanuka rya 7.49% ugereranije n’igihe nk’icyo mu kwezi gushize, izamuka rya 29.98% ugereranije n’intangiriro z’umwaka, n’izamuka rya 54.10% ugereranije n’igihe nk’icyo mu mwaka ushize.
Umuvuduko mwinshi ku giciro cya electrode za grafiti:
1. Ibiciro bya “needle coke” na “coal pitch” mu gice cyo hejuru cya “graphite electrodes” biri hejuru, kandi igiciro cya “low-sulfur petroleum coke” gikomeje kuzamuka, bituma ikiguzi cya “graphite electrodes” kiyongera.
2. Bitewe n'ibintu nko kugabanuka k'amashanyarazi muri Mongoliya y'imbere n'imyuzure muri Henan, kandi bikururwa n'inyungu nyinshi zo gukoresha electrode graphitization mbi, igice cy'ubushobozi bwo gukoresha electrode graphitization ya graphite gihinduka ubushobozi bwo gukoresha electrode graphitization mbi. Umutungo wa graphitization ya electrode graphitization ni muto, kandi electrode graphitization irashyuha, ikiguzi cyo gutunganya graphitization cyariyongereye.
Igitekerezo rusange cy’isoko rya electrode ya grafiti kiragabanyijemo ibice. Kuva igiciro cya coke ya peteroli ifite sulfur nke cyagabanutse muri Gicurasi, amwe mu masosiyete mato n’aciriritse ya electrode ya grafiti yagabanyije umusaruro bitewe n’igitekerezo cy’isoko cyo gutegereza no kureba. Muri Nyakanga-Nzeri, isoko ry’ibikoresho bya electrode ya grafiti rirarangira ritari mu gihe cy’umwaka, kandi igiciro cy’ibikoresho fatizo bikomeje kuzamuka. Amwe mu masosiyete ya electrode ya grafiti afite gahunda yo kugabanya umusaruro n’umusaruro, kandi ubushobozi bw’ibanze bw’isoko rya electrode ya grafiti bugenda bukoreshwa buhoro buhoro.
♦Inganda zikora ibicuruzwa ku giti cyazo zikora cyane mu ntangiriro z'umusaruro, kandi ziherutse gushyira ahagaragara ubushobozi bwazo mu gukora, zibanda ku bicuruzwa bikorerwa mu mahanga, ariko abakiriya ba electrode ya grafiti isanzwe ntibahinduka kandi nta gitutu kirimo ku bicuruzwa bikorerwa mu mahanga.
♦Ibice bimwe by'ibigo bito n'ibiciriritse bikora electrode ya grafiti bifite isoko rito. Byongeye kandi, bitewe n'uko igihe cyo gukenera ibicuruzwa kidakora, ibigo byibanda ku kohereza ibicuruzwa bikiri mu nzira, kandi ibiciro by'ibikorwa by'ibicuruzwa ku giti cyabyo biri hasi gato ugereranyije n'isoko.
♦Igice kimwe cy’ibigo bikora electrode ya grafiti gifite umusaruro uhamye n’ibicuruzwa bigurishwa kandi bifite ububiko buke, nubwo hari igitutu cy’ikiguzi, ikigo kidashaka kugurisha kiragaragara cyane. Kugira ngo hirindwe ihindagurika ry’ibiciro, bimwe mu bigo byongereye gato igiciro cya electrode ya grafiti.
Ku ruhande rumwe, ububiko bwa electrode ya grafiti yaguzwe n'inganda zimwe na zimwe zikora ibyuma bikoresha amashanyarazi mu ntangiriro zigenda zigabanuka buhoro buhoro. Bivugwa ko zimwe mu nganda zikora ibyuma bikoresha amashanyarazi zifite gahunda yo kugura mu gihe cya vuba.
Ku rundi ruhande, uko ibiciro by'ibikoresho fatizo bya electrode za grafiti bikomeza kuzamuka, bamwe mu bacuruzi b'ibyuma bikoresha amashanyarazi hamwe n'abacuruzi b'amashanyarazi ba electrode za grafiti bizera ko igiciro cya electrode za grafiti kiri hafi y'agace ka rebound, kandi electrode za grafiti ziri mu nzira yo guhiga hasi. Ariko, kubera igitutu cy'ibiciro by'ibigo bikoresha electrode za grafiti, hari Abatifuza kugurisha amarangamutima.
Byongeye kandi, ikirere cy’ubushyuhe bwinshi mu mpeshyi kizashira, igihe cy’isoko ry’ibicuruzwa bya graphite electrode terminal kizashira, kandi icyerekezo giherutse cyo kuzamuka kw’ibicuruzwa bizakomera, bikongera isoko, igipimo cy’imikorere y’inganda zikora ibyuma bikoresha amashanyarazi cyariyongereye gato, kandi icyifuzo cya graphite electrodes cyariyongereye.
Vuba aha, ibigo bikiri inyuma bya electrode ya grafiti bikura ibicuruzwa mu gice cyo hasi cy’umurundo wa electrode ya grafiti igiciro kiri hejuru, hari ukudashaka kugurisha isoko rya electrode ya grafiti. Mu gihe cy’igitutu cy’ibiciro n’ubusabe bwiza ku isoko rya silicon metal, igiciro cya electrode ya grafiti isanzwe n’ifite ingufu nyinshi cyafashe iya mbere mu kongera kuzamuka, kandi ibigo byigenga bya electrode ya grafiti bifite ibikoresho bike na byo byongereye gato igiciro cya electrode ya grafiti ifite ingufu nyinshi. Hamwe n’ikoreshwa ry’ibikoresho byo ku isoko rya electrode ya grafiti, biteganijwe ko hagati ya 9 nyuma yo kurangiza gupiganwa kw’ibyuma, ibiciro bya electrode ya grafiti bishobora kongera kuzamuka.
