Mu gice gishize cya 2021, bitewe n’impamvu zitandukanye za politiki, imashini itunganya peteroli ya coke irimo kugabanuka kw’ibiciro by’ibikoresho fatizo n’ibikenewe. Ibiciro by’ibikoresho fatizo byazamutseho ibirenga 50%, igice cy’uruganda rwapimye ubucuruzi, isoko rya carburizer riragoye.

Imbonerahamwe y'ibiciro by'ibikomoka kuri peteroli ku rwego rw'igihugu ijyanye n'ibiciro
Imibare igaragaza ko kuva mu mpera za Gicurasi, igiciro cya peteroli cya coke cyo mu gihugu cyazamutse, cyane cyane kuva muri Kanama kugeza ubu, izamuka ryihuta cyane. Muri byo, igiciro ku isoko cya 1#A ni yuan 5000/toni, cyazamutseho yuan 1900/toni cyangwa 61.29%. Igiciro cya 1#B ku isoko cya yuan 4700/toni, cyazamutseho yuan 2000/toni cyangwa 74.07%. Igiciro cya 2# coke ku isoko cya yuan 4500/toni, cyazamutseho yuan 1980/toni cyangwa 78.57%. Ibiciro by'ibikoresho fatizo byazamutse, bituma ibiciro bya carburizer bizamuka.
Nyuma yo gukaraba igiciro cy’isoko rya calcination coke carburizing agent, igiciro rusange cya 5500 yuan/toni (ingano y’uduce: 1-5mm, C: 98%, S≤0.5%), 1800 yuan/toni cyangwa 48.64% hejuru ugereranyije n’iya mbere. Ibiciro by’ibikoresho fatizo ku isoko byiyongera cyane, ikiguzi cyo kugura kiriyongera mu buryo butunguranye, abakora carburizer ya coke calcined bategereza bakabona ikirere gikomeye kandi cyitonze ku isoko. Isoko muri rusange, abakora imyumvire idahwitse iragaragara. Bimwe mu bigo bitewe n’ibiciro biri hejuru, bigabanya ibikoresho byo gusuzuma cyangwa bigafunga mu buryo butaziguye, igihe cyo kongera gukora ntabwo gisobanutse neza.
Igiciro rusange ku isoko rya kaburizeri ya grafitisation ni yuan 5900/toni (ingano y'uduce: 1-5mm, C: 98.5%, S≤0.05%), yuan 1000/toni cyangwa 20.41% hejuru y'iyabanje. Igipimo cyo kwiyongera kw'ibiciro bya kaburizeri ya grafitisation kiri kugenda buhoro, ibigo byigenga bitunganya ibikoresho bya anode, bikinjiza amafaranga yo kubitunganya. Ibigo bimwe na bimwe byo mu gace k'uburasirazuba bireka kaburizeri ya calcined kugira ngo bikoreshe kaburizeri ya semi-graphitized, bituma igiciro cya kaburizeri kizamuka.
Kugeza ubu, ihindagurika ry’umuvuduko wo kurekura igiciro cy’ibikoresho bishya riracyari rinini, isoko muri rusange riragabanuka. Vuba aha, bitewe n’ubukonje mu karere k’amajyaruguru, imirimo yo kubaka yaragabanutse, mu gihe akarere k’amajyepfo kakibereye igihe cy’ubwubatsi. Imijyi imwe n’imwe yo mu Burasirazuba n’Amajyepfo y’Ubushinwa yatangaje ko ibikoresho bishya bitaraboneka, kandi ibikoresho bishya ahanini ni ibikoresho binini, mu gihe ibyo umuntu akeneye ku iherezo biracyahari. Uko igihe kigenda gihita, ibyo bikoresho bishya bizaba bifite amahirwe menshi yo gukora neza.
Ibiciro by'ibikoresho fatizo bikomeje kuzamuka, kugira ngo bitange inkunga ku giciro cya recarburizer, ariko icyifuzo kiri hasi gikeneye igihe, mu gihe gito, imbaraga nyinshi zo kuzamuka. Igice kimwe cy'inganda zisuzuma cyahagaritse by'agateganyo umusaruro, isoko ry'igihe gito rishobora kutabasha kuzamuka. Biteganijwe ko igiciro ku isoko cya carburizer ya peteroli kizakomeza gukurikira igiciro cy'ibikoresho fatizo fatizo.
