Kuwunikanso msika wa ma electrode a grafiti mu theka loyamba la 2021 ndi momwe zinthu zikuyendera mu theka lachiwiri la chaka

Mu theka loyamba la chaka cha 2021, msika wa graphite electrode upitiliza kukwera. Pofika kumapeto kwa mwezi wa June, msika wa φ300-φ500 wamba wamagetsi a graphite electrode wamba unatchula mtengo wa 16000-17500 CNY/tani, zomwe zinawonjezera kuchuluka kwa 6000-7000 CNY/tani; φ300-φ500 mkulu wamagetsi a graphite electrode waukulu pamsika wa 18000-12000 CNY/tani, zomwe zinawonjezera 7000-8000 CNY/tani.

Malinga ndi kafukufuku, kukwera kwa ma electrode a graphite kumakhudza kwambiri zinthu izi:

Choyamba, kukwera kosalekeza kwa mitengo ya zinthu zopangira;

Chachiwiri, Inner Mongolia, gansu ndi madera ena mu March mphamvu brownouts, graphite mankhwala makampani ochepa, opanga ambiri angathe kokha ku Shanxi Province ndi madera ena kuti agwiritsidwe ntchito, ziwalo zimafunika graphitization foundry electrode fakitale yotulutsa yachepa chifukwa chake, UHP550mm ndi specifications zotsatirazi zoperekera katundu pamsika zikadali zolimba, mitengo yamphamvu, imawonjezeka kwambiri, yachibadwa, graphite electrode yamphamvu kwambiri, komanso kukwera mtengo kwa zinthu;

Chachitatu, opanga ma electrode a graphite ambiri ali ndi zinthu zochepa zomwe ali nazo, ndipo maoda ayitanidwa mpaka pakati pa mwezi wa Meyi mpaka kumapeto kwa mwezi wa May.

Msika:

Malinga ndi ndemanga kuchokera kwa opanga ma electrode ena, m'mbuyomu, zinthu zina zopangira zidagulidwa nthawi yomweyo pafupifupi Disembala chifukwa cha Chikondwerero cha Masika. Komabe, mu 2020, chifukwa cha kukwera kwa mitengo ya zinthu zopangira mu Disembala, opanga ankayembekezera kwambiri, kotero zinthu zopangira zida mu 2021 sizokwanira, ndipo opanga ena adzazigwiritsa ntchito mpaka Chikondwerero cha Masika chitatha. Kuyambira pachiyambi cha 2021, chifukwa cha zotsatira za zochitika zaumoyo wa anthu, makampani ambiri opangira ndi ena okhudzana nawo m'malo akuluakulu opangira ndi kupanga makina a graphite electrode ku China ayimitsa kupanga, ndipo zotsatira za kutsekedwa kwa misewu zabweretsa mavuto oyendera.

Nthawi yomweyo, kuyambira Januwale mpaka Marichi, Inner Mongolia idagwiritsa ntchito mphamvu zambiri polamulira kawiri komanso madera ena oletsa mphamvu, graphite electrode graphite chemical sequence idawoneka ngati vuto lalikulu, mpaka pakati pa Epulo kapena apo, graphitization yakumaloko idayamba pang'ono, koma kutulutsa mphamvu zopanga ndi 50-70% yokha, monga tonse tikudziwira, Inner Mongolia ndiye kuchuluka kwa graphitization ku China. Chiwerengero cha zinthu zomalizidwa zomwe zidatulutsidwa ndi wopanga graphite electrode kumapeto kwa njira yowongolera kawiri ndi theka chikadali ndi mphamvu zina. Mu Epulo, chifukwa cha kukhudzidwa kwa kukonza pakati pa zipangizo zopangira ndi ndalama zambiri zotumizira, opanga ma electrode akuluakulu adakweza kwambiri mitengo yazinthu zawo kawiri motsatizana kumayambiriro ndi pakati komanso kumapeto kwa Epulo, ndipo opanga achitatu ndi achinayi adapitilizabe pang'onopang'ono kumapeto kwa Epulo. Ngakhale mitengo yeniyeni yogulitsira inali yokwera pang'ono, kusiyana kwachepa.
Mpaka pomwe daqing petroleum coke idawonekera "kutsika kanayi motsatizana", komwe kudayambitsa zokambirana zambiri pamsika, malingaliro a aliyense adayambanso kusintha pang'ono. Ena opanga ma electrode a graphite pakati pa Meyi pomwe tender adapeza kuti opanga ma electrode a graphite pawokha amatsika pang'ono. Koma chifukwa kukhazikika kwa mitengo ya singano ya singano, komanso kupezeka kwa zinthu mochedwa kumayiko ena kudzakhala kochepa, mafakitale ambiri otsogola a graphite electrode amaganiza kuti mitengo ipitilizabe kukhalabe momwe ilili kapena ma electrode mochedwa adasinthasintha mtengo wazinthu zopangira, pambuyo pake, kupanga kuli pamzere wopanga, ma electrode adzakhudzidwabe ndi kutsika kwa mitengo posachedwa sizingatheke.
