1. Ikiguzi
Ibintu byiza: Igiciro cya needle coke cyatumijwe mu gihugu cy’Ubushinwa cyazamuweho amadolari y’Amerika 100 kuri toni, kandi igiciro cyiyongereye kizashyirwa mu bikorwa muri Nyakanga, ibi bishobora gutuma igiciro cya needle coke cyiza cyane mu Bushinwa gikomeza kwiyongera, kandi ikiguzi cyo gukora electrodes za grafiti zifite ingufu nyinshi kiracyari hejuru.
Ibintu bibi: Igiciro cy’isoko rya peteroli rya coke nkeya cyazamutse cyane mu ntangiriro z’iki gihe, kandi isoko rya peteroli rya coke nkeya ryatangiye gukora nabi vuba aha, kandi igiciro cyasubiye mu bwenge buhoro buhoro. Ikiguzi cya coke nkeya cya sulfure cyagabanutse, hamwe n’ibicuruzwa bibi biva mu nganda zitunganya coke nkeya, kandi ibiciro nabyo byaragabanutse, bituma habaho igitekerezo cyo gutegereza no kureba ku isoko rya electrode ya grafiti.
Muri rusange: Nubwo igiciro cya coke ya peteroli ifite sulfur nke cyagabanutse, kiracyariyongeraho 68.12% ugereranyije n'igihe nk'icyo umwaka ushize; igiciro cya coke ya needle yo mu gihugu nk'ibikoresho fatizo bya electrode ya grafiti kiri hejuru kandi igiciro cya coke ya needle yo mu mahanga cyariyongereye. Kuri ubu, electrode za grafiti zo mu gihugu Igiciro cya coke ya needle kiri hagati ya yuan 9000-10000/toni; igiciro cya coke ya needle yo mu gihugu kiri hagati ya 1600-1800 by'amadolari y'Amerika/toni. Igiciro cya pitch y'amakara kirahindagurika ku rwego rwo hejuru kandi kiri mu rugero ruto. Pitch yahinduwe ku bicuruzwa bya grafiti ni yuan 5650/toni. , Igiciro rusange cy'isoko rya electrode ya grafiti kiracyari hejuru.

2. Ku ruhande rw'ibicuruzwa
Mu gihe cya vuba aha, haracyari inkunga nziza ku isoko ku bijyanye no gutanga electrode za grafiti. Isesengura ryihariye ni iri rikurikira:
1. Ibicuruzwa byose by’isoko rya electrode ya grafiti biracyari ku rwego rwo hasi kandi rukwiye. Ibigo byinshi by’amashanyarazi bya grafiti bigaragaza ko nta bubiko burenze urugero bifite, kandi isoko rya electrode ya grafiti muri rusange nta bubiko cyangwa igitutu bifite.
ishusho
2. Birumvikana ko amwe mu masosiyete ya electrode ya grafiti agaragaza ko bimwe mu bipimo bya electrode ya grafiti bitakiriho (cyane cyane imbaraga nyinshi cyane za 450mm). Bigaragara ko gutanga imiterere y'amashanyarazi menshi cyane n'iy'ibipimo bito bigifite imiterere idakomeye.
3. Dukurikije ibitekerezo byatanzwe n’ibigo bimwe na bimwe bikoresha amashanyarazi ya grafiti, isoko ry’ibikoresho byiza bya needle coke mu Bushinwa ryari rito muri Kamena, kandi kubera kubungabunga ikigo cya needle coke mu Bwongereza kuva muri Gashyantare kugeza muri Gicurasi, needle coke yatumijwe mu mahanga yageze muri Hong Kong muri Nyakanga na Kanama, bituma Ubushinwa butumiza ibicuruzwa bya needle coke mu mahanga. Ibi byagizweho ingaruka n’ibi, bimwe mu bigo bikoresha amashanyarazi ya grafiti byahagaritse ikorwa rya electrode za grafiti zikomeye cyane n’izinini. Kuri ubu, isoko ry’ibikoresho bya grafiti bifite ubunini bwinshi cyane ku isoko riri mu rwego rwo kuringaniza neza.
4. Bitewe n’izamuka ry’igiciro cya koke y’inzoga ituruka mu Bushinwa, amwe mu masosiyete acuruza amashanyarazi ya grafiti ntashaka kugurisha, kandi isoko ry’amashanyarazi ya grafiti muri rusange riracyari rito kandi rito.
3. Ubusabe bukurikira
Ibintu byiza
1. Vuba aha, imikorere y’inganda z’ibyuma bikoresha amashanyarazi bya electrode za grafiti mu matanura y’amazi yari ihamye, kandi impuzandengo y’imikorere y’inganda z’ibyuma bikoresha amashanyarazi yagumye imeze nka 70%, kandi electrode ya grafiti igomba kuba ihamye.

2. Isoko ry’amashanyarazi yoherezwa mu mahanga rya graphite electrode ryatewe inkunga vuba aha. Dukurikije imibare ya gasutamo, ingano y’amashanyarazi yoherezwa mu mahanga ya graphite electrode mu Bushinwa yari toni 34.600 muri Gicurasi 2021, ubwiyongere bwa 5.36% buri kwezi n’ubwiyongere bwa 30.53% buri mwaka; amashanyarazi yose yoherezwa mu mahanga ya graphite mu Bushinwa kuva muri Mutarama kugeza muri Gicurasi 2021 yari toni 178.500, ubwiyongere bwa 25.07% buri mwaka. Kandi byumvikana ko amwe mu masosiyete ya graphite electrode yavuze ko ayoherezwa mu mahanga ari meza kandi ko isoko ryoherezwa mu mahanga rihagaze neza.

3. Vuba aha, umubare w'amatanura ku isoko rya silicon metal wariyongereye buhoro buhoro. Ku ya 17 Kamena, umubare w'amatanura ya silicon metal wiyongereyeho 10 ugereranije n'impera za Gicurasi. Umubare w'amatanura mu mibare ya Baichuan ni 652 naho umubare w'amatanura ni 246. Ubukene bwa electrodes zisanzwe za grafiti y'ingufu bwagaragaje ukwiyongera guhoraho, hagati n'aho ari gake.
Ibintu bibi
1. Ku bijyanye n'ibyuma bikoreshwa mu itanura ry'amashanyarazi, bitewe n'igihe gito gishize mu nganda, kugurisha ibicuruzwa birangiye byaragabanutse, kandi igiciro cy'ibikoresho birangiye cyakomeje kuba gito vuba aha, kandi igiciro cy'ibikoresho birangiye cyagabanutse cyane kurusha igiciro cy'ibyuma bishaje. Inyungu y'inganda zikora ibyuma bikoreshwa mu itanura ry'amashanyarazi yaragabanutse, kandi igiciro cya coke ya peteroli ifite sulfur nkeya cyaragabanutse vuba aha. , Inganda zikora ibyuma zifite igitekerezo cyo gutegereza no kureba igiciro cya electrode za grafiti, kandi hari imyitwarire runaka yo kugabanya ibiciro ku kugura electrode za grafiti.
2. Igiciro cy’imizigo cy’amato yohereza electrode ya grafiti kiracyari hejuru, ibyo bigatuma electrode za grafiti zoherezwa mu mahanga ku rugero runaka zitabasha koherezwa mu mahanga.
Icyerekezo cy'isoko: Nubwo hari igitekerezo cyo gutegereza no kureba ku isoko rya electrode ya grafiti vuba aha, ikiguzi rusange cy'umusaruro w'isoko rya electrode ya grafiti kiracyari hejuru, kandi amashanyarazi ya electrode ya grafiti aracyari make kandi akomeye, ibyo bikaba ari byiza ku giciro gikomeye cy'amasosiyete akomeye ya electrode ya grafiti. Biteganijwe ko igiciro gihamye cy'isoko rya electrode ya grafiti kizakora nk'Umwami. Byongeye kandi, igiciro cyo hejuru cya needle coke itumizwa mu mahanga gishyigikira ikiguzi cya electrode ya grafiti. Bitewe n'uko amasosiyete akomeye ya electrode ya grafiti yanga kugurisha, aracyari hejuru ku ma electrode manini ya grafiti afite imbaraga nyinshi.
