Kuwunika kwa msika wa graphite electrode mu theka loyamba la 2021 ndikuwonetsa theka lachiwiri la 2021

Mu theka loyamba la 2021, msika wa graphite electrode upitilira kukwera. Pofika kumapeto kwa June, msika wamba wa φ300-φ500 wamba wamagetsi a graphite adatchulidwa pa 16000-17500 yuan/ton, ndi kuwonjezeka kwa 6000-7000 yuan/ton; φ300-φ500 mkulu Mtengo wamsika wamagetsi wamagetsi a graphite ndi 18000-12000 yuan/tani, ndi kuwonjezereka kwa 7000-8000 yuan/ton.

Malinga ndi kafukufukuyu, kukwera kwa ma electrode a graphite makamaka kumakhala ndi izi:

Choyamba, zimakhudzidwa ndi kuwonjezeka kosalekeza kwa mitengo yamtengo wapatali;

Chachiwiri, ku Inner Mongolia, Gansu ndi madera ena, munali kudula mphamvu mu March, ndipo ndondomeko ya graphitization inali yochepa. Opanga ambiri amatha kungotembenukira ku Shanxi ndi zigawo zina kuti akakonze. Zotsatira za mafakitale ena a electrode zomwe zimafuna graphitization foundry zinachepetsedwa chifukwa chake. Kupereka kwa UHP550mm ndi pansi pazidziwitso kumakhalabe kolimba, mtengo ndi wolimba, kuwonjezeka kukuwonekera, ndipo ma electrode wamba ndi apamwamba a graphite amatsatira kuwonjezeka;

Chachitatu, opanga ma elekitirodi a graphite ambiri alibe zinthu zokwanira, ndipo maoda adayikidwa mpaka pakati mpaka kumapeto kwa Meyi.

Pamsika:

Malinga ndi mayankho ochokera kwa opanga ma elekitirodi, m'mbuyomu, pa Chikondwerero cha Spring kapena nthawi yomweyo, amagula kuchuluka kwazinthu zopangira. Komabe, mu 2020, chifukwa cha kukwera kosalekeza kwa mtengo wazinthu zopangira mu Disembala, opanga makamaka amadikirira ndikuwona. Chifukwa chake, zopangira zida mu 2021 ndizosakwanira, ndipo opanga ena Kugwiritsa ntchito kupitilira mpaka Chikondwerero cha Spring. Kuyambira kuchiyambi kwa 2021, chifukwa cha zochitika zaumoyo wa anthu, makampani ambiri okonza ndi ogwirizana nawo, omwe ndi malo akuluakulu opanga ma graphite electrode machining mdziko muno, ayimitsa ntchito ndi kupanga, ndipo kukhudzidwa kwa kutsekedwa kwa misewu kwadzetsa zovuta zamayendedwe.
Panthawi imodzimodziyo, kulamulira kwapawiri kwa mphamvu zamagetsi ku Inner Mongolia ndi kudula mphamvu ku Gansu ndi madera ena kuyambira Januwale mpaka March kunayambitsa zovuta kwambiri mu ndondomeko ya graphitization ya maelekitirodi a graphite. Mpaka cha m'ma April, graphitization m'deralo anayamba bwino pang'ono, koma mphamvu kupanga anamasulidwa. Ndi 50-70% yokha. Monga tonse tikudziwa, Inner Mongolia ndiye likulu la graphitization ku China. Kuwongolera kwapawiri kumakhudzanso kutulutsidwa kwapambuyo kwa opanga ma elekitirodi a semi-process graphite electrode. Kukhudzidwa ndi kukonza kwapakati kwa zopangira komanso kukwera mtengo kwa zoperekera mu Epulo, opanga ma elekitirodi ambiri adawonjezera mitengo yawo yazinthu kawiri koyambirira komanso pakati mpaka kumapeto kwa Epulo, ndipo opanga echelon yachitatu ndi yachinayi adasunga pang'onopang'ono kumapeto kwa Epulo. Ngakhale mitengo yeniyeni yogulitsira inali yabwino, Koma kusiyana kwachepa.
Mpaka "madontho anayi otsatizana" a Daqing petroleum coke, panali zokambirana zambiri zotentha pamsika, ndipo maganizo a aliyense anayamba kusintha pang'ono. Ena opanga ma elekitirodi a graphite adapeza kuti mitengo ya ma elekitirodi a graphite a opanga pawokha inali yotayirira pang'ono panthawi yotsatsa pakati mpaka kumapeto kwa Meyi. Komabe, chifukwa mtengo wa singano zapakhomo ukhalabe wokhazikika komanso kuperekedwa kwa coke kumayiko akunja kudzakhala kolimba m'nthawi yamtsogolo, opanga ambiri opanga ma elekitirodi a graphite amakhulupirira kuti mtengo wa electrode yamtsogolo ukhalabe momwe ulili kapena kusinthasintha pang'ono. Kupatula apo, zida zamtengo wapatali zikadali pakupanga. Kupanga, maelekitirodi adzakhudzidwabe ndi ndalama posachedwa, sizingatheke kuti mitengo igwe.
