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

Mu theka loyamba la chaka cha 2021, msika wa ma electrode a graphite upitiliza kukwera. Pofika kumapeto kwa Juni, msika waukulu wa ma electrode a φ300-φ500 wamba wa graphite unatchulidwa pa 16000-17500 yuan/tani, ndi kuwonjezeka kwa 6000-7000 yuan/tani; φ300-φ500 okwera Mtengo waukulu pamsika wa ma electrode a graphite amphamvu ndi 18000-12000 yuan/tani, ndi kuwonjezeka kwa 7000-8000 yuan/tani.

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

Choyamba, zimakhudzidwa ndi kukwera kosalekeza kwa mitengo ya zinthu zopangira;

Chachiwiri, ku Inner Mongolia, Gansu ndi madera ena, magetsi adachepa mu Marichi, ndipo njira yogwiritsira ntchito graphitization inali yochepa. Opanga ambiri ankangogwiritsa ntchito Shanxi ndi madera ena kuti agwiritsidwe ntchito. Zotsatira zake, kutulutsa kwa mafakitale ena a electrode omwe amafunikira maziko a graphitization kunachepetsedwa. Kupereka kwa UHP550mm ndi pansi pa zofunikira kudakali kochepa, mtengo wake ndi wolimba, kuwonjezeka kwake kukuwonekera bwino, ndipo ma electrode wamba komanso amphamvu kwambiri a graphite amatsatira kuwonjezekako;

Chachitatu, opanga ma electrode a graphite ambiri alibe zinthu zokwanira, ndipo maoda aperekedwa mpaka pakati pa Meyi mpaka kumapeto kwa mwezi wa May.

Pamsika:

Malinga ndi ndemanga kuchokera kwa opanga ma electrode ena, m'mbuyomu, panthawi ya Chikondwerero cha Masika kapena nthawi yomweyo, ankagula zinthu zinazake zopangira. Komabe, mu 2020, chifukwa cha kukwera kosalekeza kwa mitengo ya zinthu zopangira mu Disembala, opanga amayembekezera kwambiri kuti awone. Chifukwa chake, zinthu zopangira mu 2021 sizokwanira, ndipo opanga ena amagwiritsa ntchito mpaka Chikondwerero cha Masika. Kuyambira pachiyambi cha 2021, chifukwa cha zochitika zaumoyo wa anthu, makampani ambiri opangira zinthu ndi ena ofanana nawo, omwe ndi malo akuluakulu opangira ma electrode a graphite mdziko muno, ayimitsa ntchito ndi kupanga, ndipo zotsatira za kutsekedwa kwa misewu zabweretsa mavuto oyendera.
Nthawi yomweyo, kuwongolera mphamvu ziwiri ku Inner Mongolia komanso kuchepetsedwa kwa mphamvu ku Gansu ndi madera ena kuyambira Januwale mpaka Marichi kunayambitsa mavuto akulu pakupanga ma graphite electrodes. Mpaka pakati pa Epulo, kupanga ma graphite m'deralo kunayamba kusintha pang'ono, koma mphamvu zopangira zinatulutsidwanso. Ndi 50-70% yokha. Monga tonse tikudziwira, Inner Mongolia ndiye likulu la kupanga ma graphite ku China. Kuwongolera kawiri kumakhudza kutulutsidwa kwa opanga ma electrode a semi-process graphite. Pokhudzidwa ndi kukonza pakati pa zinthu zopangira komanso mtengo wokwera wotumizira mu Epulo, opanga ma electrode akuluakulu adakweza mitengo yazinthu zawo kawiri kwambiri kumayambiriro ndi pakati mpaka kumapeto kwa Epulo, ndipo opanga achitatu ndi achinayi adapitiliza pang'onopang'ono kumapeto kwa Epulo. Ngakhale mitengo yeniyeni yogulitsira inali yabwino pang'ono, Koma kusiyana kwachepa.
Mpaka "madontho anayi otsatizana" a Daqing petroleum coke, panali makambirano ambiri okangana pamsika, ndipo malingaliro a aliyense anayamba kusintha pang'ono. Opanga ma electrode ena a graphite adapeza kuti mitengo ya ma electrode a graphite a opanga payekhapayekha inali yofooka pang'ono panthawi yopereka ma bidding pakati pa kumapeto kwa Meyi. Komabe, chifukwa mtengo wa needle coke wakunyumba ukhalabe wokhazikika ndipo kupezeka kwa coke wakunja kudzakhala kochepa mtsogolo, opanga ma electrode ambiri otsogola a graphite amakhulupirira kuti mtengo wa electrode yotsatira udzakhalabe momwe ulili kapena kusinthasintha pang'ono. Kupatula apo, zopangira zamtengo wapatali zikadali pamzere wopanga. Kupanga, ma electrode adzakhudzidwabe ndi ndalama posachedwa, sizingatheke kuti mitengo itsike.
