Ukususela ekupheleni kukaMeyi ukuya ekuqaleni kukaJuni, kuza kuqaliswa umjikelo omtsha wohlengahlengiso lwamaxabiso kwimarike ye-needle coke. Nangona kunjalo, okwangoku, imakethi ye-needle coke ilawulwa sisimo sengqondo sokulinda nokubona. Ngaphandle kwamanye amashishini ahlaziya ixabiso ngoJuni aze akhokele ekunyuseni i-300 yuan/ton kancinci, intengiselwano yokwenyani ayikafiki. Ixabiso lemakethi ye-needle coke yaseTshayina kufuneka liziphathe njani ngoJuni, kwaye liqhubeke nomkhwa okhulayo ngoMeyi?
Ukusuka kwindlela amaxabiso e-needle coke ahamba ngayo, kubonakala ukuba ixabiso le-needle coke liqinile kwaye linyuka ukusuka ngoMatshi ukuya ku-Epreli, lize lihlale lizinzile emva kokunyuswa ekuqaleni kukaMeyi. NgoMeyi, ixabiso eliqhelekileyo le-coke esekwe kwioyile yi-10,500-11,200 yuan/ton, elo le-coke esekwe kwioyile yi-14,000-15,000 yuan/ton, elo le-coke esekwe kumalahle yi-9,000-10,000 yuan/ton, kwaye elo le-coke esekwe kumalahle yi-12,200 yuan/ton. Okwangoku, kukho izizathu ezininzi zokuba i-needle coke ilinde ize ibone:
1. Ixabiso le-petroleum coke ene-sulfur ephantsi liye lehla. Ekupheleni kukaMeyi, ixabiso le-petroleum coke eqhelekileyo ene-sulfur ephantsi eDagang naseTaizhou lakhokela, kwaza emva koko iJinzhou Petrochemical yalandela. Ngomhla woku-1 kuJuni, ixabiso leJinxi Petrochemical lehla laya kwi-6,900 yuan/ton, kwaye umahluko wamaxabiso phakathi kweDaqing kunye neFushun petroleum coke ekumgangatho ophezulu wanda waya kwi-2,000 yuan/ton. Ngokuhla kwe-petroleum coke ene-sulfur ephantsi, amanye amashishini asezantsi anyuse umlinganiselo wokuxuba we-petroleum coke, nto leyo eyachaphazela imfuno ye-needle coke ukuya kwinqanaba elithile. Ishishini le-needle coke kufuneka libhekisele kwixabiso le-petroleum coke eDaqing naseFushun. Okwangoku, akukho xinzelelo kwiisitokhwe ezimbini, kwaye akukho sicwangciso sokulungisa ezantsi okwangoku, ngoko ke imakethi ye-needle coke iya kulinda ize ibone.
2. Imfuno yokuthengwa kwe-electrode engalunganga ezantsi iyehla. Phantsi kwempembelelo yemeko yobhubhane, ii-odolo zeebhetri zamandla kunye neebhetri zedijithali zehla ngoMeyi. Izinto ezisetyenziswa kwi-needle coke yezinto ze-anode zacutshungulwa kakhulu kwinqanaba lokuqala, kwaye inani lee-odolo ezintsha lehla. Amanye amashishini, ngakumbi i-needle coke esekwe kumalahle, andise uluhlu lwawo lwezinto.
3. Imveliso ye-graphite electrode ihlale iphantsi. Inzuzo ye-steel mills ayilunganga, kwaye amashishini e-graphite electrode achatshazelwa yimeko yobhubhane, ukhuseleko lokusingqongileyo kunye namaxabiso aphezulu ezinto eziluhlaza, ngoko ke umdla wabo wokuqala ukwakha awuphezulu kwaye imveliso yabo iphantsi. Ke ngoko, umthamo we-needle coke ulinganiselwe. Amanye amashishini amancinci emveliso asebenzisa i-low-sulfur petroleum coke endaweni ye-needle coke.
Uhlalutyo lwembono yemarike: Kwixesha elifutshane, amashishini e-anode adla ngokucola isitokhwe sezinto eziluhlaza ekuqaleni, aze asayine ii-odolo ezintsha ezimbalwa. Ukongeza, ixabiso lesizwe le-bureau ye-petroleum coke esezantsi-sulfur liya kuba nefuthe elithile ekuthunyelweni kwe-needle coke. Nangona kunjalo, amashishini e-needle coke aneendleko eziphezulu zemveliso, kwaye akunakwenzeka ukuba ixabiso liwele phantsi koxinzelelo lwenzuzo. Ke ngoko, imakethi ye-needle coke iya kuqhubeka ilawula ngoJuni kwimeko yokulinda nokubona. Kwixesha elide, ngemeko yobhubhane eShanghai nakwezinye iindawo ezilawulwayo, imveliso yeemoto kulindeleke ukuba ibuye kancinci kancinci, kwaye imfuno yokugqibela kulindeleke ukuba inyuke. Ukongeza, kwikota yesithathu, ezinye izinto ze-electrode ezimbi ziya kufakwa kwimveliso, nto leyo eya kwandisa imfuno yezinto eziluhlaza ze-needle coke. Xa amashishini e-electrode ezimbi eqala ukugcina izinto eziluhlaza, imeko eqinileyo ye-needle coke iya kuphinda idale inkxaso efanelekileyo yamaxabiso.
