Kev txheeb xyuas kev ua lag luam:
Tag nrho cov lag luam graphite electrode qhia tau tias muaj kev nce siab tas li. Vim muaj kev nce nqi ntawm cov khoom siv raw thiab kev muaj cov khoom siv graphite me me thiab nruab nrab uas muaj zog heev hauv kev ua lag luam, tus nqi ntawm graphite electrodes tau khaws cia kom loj hlob tas li thaum Lub Ib Hlis thiab Lub Ob Hlis, feem ntau ntawm 500-1000 yuan / ton. Pib thaum Lub Peb Hlis, cov lag luam xws li cov hlau hluav taws xob hauv qab ntawm graphite electrodes maj mam rov pib tsim khoom, thiab cov chaw tsim khoom hlau tau pib sib tw ib qho tom qab ib qho. Thaum nruab nrab mus txog lig Lub Peb Hlis, cov haujlwm yuav khoom ntawm cov chaw tsim khoom hlau tseem ua haujlwm, thiab kev thov graphite electrodes hauv qab tau txhim kho tas li. Tib lub sijhawm, tus nqi ntawm cov khoom siv raw sab saud ntawm graphite electrodes. Vim muaj kev loj hlob tas li, qee lub tuam txhab graphite electrode kuj tau siv lub sijhawm los hloov lawv txoj kev sib raug zoo ntawm cov nyiaj tau los thiab kev poob. Tus nqi ntawm graphite electrodes tau pom kev nce siab heev, feem ntau yog nyob rau hauv qhov ntau ntawm 2000-3000 yuan / ton.
1. Tus nqi ntawm cov khoom siv raw yog siab, thiab tus nqi ntawm graphite electrodes yog nyob rau hauv kev nyuaj siab
Txij li lub Cuaj Hli xyoo tas los, tus nqi khoom siv raw ntawm kev lag luam graphite electrode tau nkag mus rau hauv txoj kab nce siab, thiab tus nqi ntawm cov khoom siv graphite electrode tau nce siab heev hauv peb lub hlis twg ntawm lub xyoo no. Tshwj xeeb, cov roj av coke uas muaj sulfur tsawg thiab cov roj coke koob raug cuam tshuam los ntawm kev saib xyuas lub chaw ua roj av, kev ua haujlwm tsis zoo thiab lwm yam, thiab ob qho tib si tau nce ntau dua 45% piv rau thaum pib ntawm lub xyoo. Cuam tshuam los ntawm tus nqi ntawm cov roj av coke uas muaj sulfur tsawg, tus nqi ntawm cov roj calcined uas muaj sulfur tsawg kuj tseem nce siab. Tus nqi ntawm Jinxi cov roj calcined uas muaj sulfur tsawg tau mus txog 5,300 yuan / ton.
Thaum kawg ntawm lub Peb Hlis, tus nqi ntawm cov khoom siv graphite electrode raw tau mus txog qib siab, thiab qee lub tuam txhab downstream tau qhia tias nws nyuaj rau dais cov nqi khoom siv tam sim no. Cov tuam txhab graphite electrode tau hais tias txawm hais tias tus nqi ntawm graphite electrodes tau ntsib ntau qhov kev nce ntxiv, nws tseem tsis siab npaum li qhov kev nyuaj siab ntawm tus nqi los ntawm tus nqi nce ntawm cov khoom siv raw upstream.
2. Tus qauv khoom nruj tsis yooj yim hloov pauv
Kev lag luam graphite electrode tag nrho tseem tswj hwm cov qauv kev muab khoom tsawg ntawm qee cov peev txheej (UHP550mm thiab qis dua cov lus qhia). Cov xaj rau qee lub tuam txhab graphite electrode tau teem sijhawm rau lub Tsib Hlis. Kev muab khoom tsawg ntawm kev lag luam graphite electrode feem ntau cuam tshuam los ntawm cov hauv qab no.
1. Tus nqi ntawm cov khoom siv graphite electrode raw khoom kim heev, thiab nws nyuaj rau cov lag luam dais nws. Thiab qee lub tuam txhab graphite electrode tau hais tias muaj qee qhov kev pheej hmoo hauv kev tsim khoom tam sim no, yog li cov tuam txhab tsis kam tsim ntau ntxiv kom nce lawv cov khoom muag.
2. Cov tuam txhab graphite electrode xav kom tswj tau qhov kev muab khoom thiab kev thov tam sim no kom tswj tau qhov kev loj hlob ruaj khov ntawm cov nqi lag luam graphite electrode.
3. Lub voj voog tsim cov graphite electrode ntev heev, thiab qhov cuam tshuam rau qhov xwm txheej ntawm kev muab khoom lag luam graphite electrode tsuas yog txwv rau lub sijhawm luv luv.
3. Qhov kev thov rau cov electrodes graphite feem ntau zoo dua, thiab kev yuav khoom hauv qab tseem nyob ntawm ntug kev
Thaum Lub Peb Hlis, cov hlau mills ntawm graphite electrodes txuas ntxiv mus twv, thiab kev ua lag luam maj mam ua haujlwm, thiab qhov kev thov rau graphite electrodes tau zoo dua.
Vim tias tus nqi ntawm cov graphite electrodes nce me ntsis, cov tuam txhab downstream ntawm graphite electrodes muaj qee qhov kev xav tos thiab saib tsis ntev los no, thiab lawv cov kev yuav khoom feem ntau yog raws li kev thov nruj. Txawm li cas los xij, vim muaj kev muab graphite electrodes tsawg, cov tuam txhab downstream muaj lub siab zoo dua rau kev yuav graphite electrode.
Tangshan txoj cai txwv kev tsim khoom tiv thaiv ib puag ncig thiab kev rov qab los ntawm kev thov rov qab los ntawm cov khoom siv rov qab los kuj muaj feem cuam tshuam. Tus nqi ntawm cov hlau rebar nyuam qhuav rov qab los me ntsis. Nyob rau hauv kev cuam tshuam ntawm txoj cai txwv kev tsim khoom tiv thaiv ib puag ncig, tus nqi pov tseg tau ua haujlwm tsis zoo, thiab cov txiaj ntsig ntawm cov hlau hluav taws xob tau rov qab los, uas zoo rau qhov kev thov rau graphite electrodes.
Lub keeb kwm yav dhau los ntawm "carbon neutrality" yog qhov zoo rau cov tuam txhab hluav taws xob hlau, thiab qhov kev thov rau graphite electrodes yog qhov zoo hauv nruab nrab thiab ntev.
