Nyob rau thawj ib nrab ntawm xyoo 2021, kev lag luam graphite electrode yuav txuas ntxiv nce siab. Txij li thaum kawg ntawm lub Rau Hli, kev lag luam hauv tsev ntawm φ300-φ500 lub zog graphite electrodes tau hais txog ntawm 16000-17500 yuan / ton, nrog rau kev nce ntxiv ntawm 6000-7000 yuan / ton; φ300-φ500 siab Tus nqi lag luam tseem ceeb ntawm lub zog graphite electrodes yog 18000-12000 yuan / ton, nrog rau kev nce ntxiv ntawm 7000-8000 yuan / ton.
Raws li kev soj ntsuam, qhov nce ntawm graphite electrodes feem ntau muaj cov hauv qab no:
Ua ntej, nws raug cuam tshuam los ntawm kev nce nqi ntawm cov khoom siv raw;
Qhov thib ob, hauv Inner Mongolia, Gansu thiab lwm thaj chaw, muaj kev txiav hluav taws xob thaum lub Peb Hlis, thiab cov txheej txheem graphitization raug txwv. Ntau lub chaw tsim khoom tsuas yog tig mus rau Shanxi thiab lwm thaj chaw rau kev ua tiav. Cov khoom tsim tawm ntawm qee lub Hoobkas electrode uas xav tau graphitization foundry tau qeeb qeeb vim li ntawd. Kev muab khoom ntawm UHP550mm thiab qis dua cov lus qhia tseem nruj, tus nqi ruaj khov, qhov nce ntxiv pom tseeb dua, thiab cov electrodes graphite zoo tib yam thiab muaj zog siab ua raws li qhov nce ntxiv;
Qhov thib peb, cov chaw tsim khoom siv graphite electrode feem ntau tsis muaj cov khoom muag txaus, thiab cov xaj tau muab tso rau txog thaum nruab nrab mus txog rau thaum kawg ntawm lub Tsib Hlis.
Nyob rau hauv kev ua lag luam:
Raws li cov lus tawm tswv yim los ntawm qee lub tuam txhab tsim hluav taws xob, yav dhau los, thaum lub caij nplooj ntoos hlav lossis li ntawd thaum lub sijhawm tib yam, lawv yuav yuav qee yam khoom siv raw. Txawm li cas los xij, xyoo 2020, vim yog tus nqi ntawm cov khoom siv raw nce ntxiv hauv lub Kaum Ob Hlis, cov tuam txhab tsim khoom feem ntau tos thiab saib. Yog li ntawd, cov khoom siv raw hauv xyoo 2021 tsis txaus, thiab qee lub tuam txhab tsim khoom siv yuav kav ntev txog Lub Caij Nplooj Ntoos Hlav. Txij li thaum pib ntawm xyoo 2021, vim muaj teeb meem kev noj qab haus huv pej xeem, feem ntau ntawm cov tuam txhab ua khoom thiab cov tuam txhab cuam tshuam, uas yog lub hauv paus tsim khoom graphite electrode machining loj tshaj plaws hauv lub tebchaws, tau ncua kev ua haujlwm thiab kev tsim khoom, thiab qhov cuam tshuam ntawm kev kaw txoj kev tau ua rau muaj teeb meem kev thauj mus los.
Tib lub sijhawm ntawd, kev tswj hwm kev siv hluav taws xob ob npaug hauv Inner Mongolia thiab kev txiav hluav taws xob hauv Gansu thiab lwm thaj chaw txij lub Ib Hlis mus txog lub Peb Hlis ua rau muaj kev cuam tshuam loj heev hauv cov txheej txheem graphitization ntawm graphite electrodes. Txog thaum nruab nrab lub Plaub Hlis, qhov kev graphitization hauv zos pib zoo dua me ntsis, tab sis lub peev xwm tsim khoom kuj tau tso tawm. Nws tsuas yog 50-70%. Raws li peb txhua tus paub, Inner Mongolia yog qhov chaw ntawm graphitization hauv Suav teb. Kev tswj hwm ob npaug muaj qee qhov cuam tshuam rau kev tso tawm tom qab ntawm cov tuam txhab graphite electrode semi-process. Cuam tshuam los ntawm kev saib xyuas cov khoom siv raw thiab tus nqi xa khoom siab hauv lub Plaub Hlis, cov tuam txhab electrode tseem ceeb tau nce lawv cov nqi khoom ntau ob zaug thaum ntxov thiab nruab nrab mus rau lig lub Plaub Hlis, thiab cov tuam txhab thib peb thiab thib plaub maj mam khaws cia thaum kawg lub Plaub Hlis. Txawm hais tias cov nqi pauv pauv tiag tiag tseem zoo me ntsis, Tab sis qhov sib txawv tau nqaim dua.
Txog thaum "plaub tee dej sib law liag" ntawm Daqing roj av coke, muaj kev sib tham ntau heev hauv kev ua lag luam, thiab txhua tus neeg lub siab pib hloov me ntsis. Qee cov chaw tsim khoom siv graphite electrode pom tias tus nqi ntawm graphite electrodes ntawm cov chaw tsim khoom ib leeg tau xoob me ntsis thaum lub sijhawm twv rau nruab nrab mus txog thaum kawg ntawm lub Tsib Hlis. Txawm li cas los xij, vim tias tus nqi coke koob hauv tsev tseem ruaj khov thiab kev muab khoom ntawm cov coke txawv teb chaws yuav nruj heev rau lub sijhawm tom qab, ntau tus thawj coj graphite electrode tuam txhab ntseeg tias tus nqi ntawm cov electrode tom qab yuav tseem nyob li qub lossis hloov pauv me ntsis. Tom qab tag nrho, cov khoom siv raw kim heev tseem nyob ntawm kab ntau lawm. Kev tsim khoom, electrodes tseem yuav raug cuam tshuam los ntawm cov nqi yav tom ntej, nws tsis zoo li tias tus nqi yuav poob.
