Muaj Cov ຊ່ອງ ຫວ່າງ Hauv kiab khw Graphite Electrode, Thiab Tus Qauv Ntawm Cov Khoom Siv Me Me Tseem Yuav Txuas Ntxiv

Lub graphite electrode kev ua lag luam, uas tau tsis zoo xyoo tas los no, tau ua qhov hloov loj dua rau xyoo no.
"Hauv thawj ib nrab ntawm lub xyoo, peb cov kab hluav taws xob graphite yeej tsis txaus." Raws li kev ua lag luam sib txawv nyob rau xyoo no yog txog 100,000 tons, cia siab tias qhov kev sib txuas nruj ntawm kev muab thiab kev thov yuav txuas ntxiv.

Nws to taub tias txij li lub Ib Hlis xyoo no, tus nqi ntawm graphite electrode tau nce ntxiv tsis tu ncua, los ntawm kwv yees li 18,000 yuan / ton thaum pib ntawm lub xyoo mus txog 64,000 yuan / ton ntawm tam sim no, nrog nce 256%. Nyob rau tib lub sijhawm, rab koob coke, yog cov khoom siv tseem ceeb tshaj plaws ntawm graphite electrode, tau dhau los ua qhov tsis txaus, thiab nws tus nqi tau nce txhua txoj hauv kev, uas tau nce ntau dua 300% piv nrog xyoo pib ntawm lub xyoo.
Xav tau ntawm cov lag luam hlau nqes hav iav yog muaj zog

Graphite electrode feem ntau yog ua los ntawm roj av coke thiab koob coke ua raw cov ntaub ntawv thiab thee tar pitch ua tus binder, thiab feem ntau yog siv rau hauv arc steelmaking rauv, submerged arc rauv, ua haujlwm rauv taws, thiab lwm yam. 80% ntawm tag nrho cov kev noj ntawm graphite electrode.
Hauv xyoo 2016, vim muaj kev poob qis hauv EAF steelmaking, qhov kev ua haujlwm tag nrho ntawm cov lag luam carbon tsis kam. Raws li kev txheeb cais, qhov muag tag nrho cov teeb meem ntawm graphite electrodes hauv Suav tau poob los ntawm 4.59% xyoo-xyoo-xyoo-xyoo 2016, thiab tag nrho cov kev poob ntawm kaum sab saum toj graphite electrode kev lag luam yog 222 lab Yuan. Txhua qhov kev lag luam carbon sib ntaus sib tua tus nqi kev ua lag luam kom nws cov lag luam sib faib khoom, thiab tus nqi muag khoom ntawm graphite electrode yog ntau qis dua tus nqi.

Cov xwm txheej no tau raug thim rov qab xyoo no. Nrog txoj kev hloov kho ntxiv rau sab hauv, qhov kev lag luam hlau thiab hlau txuas ntxiv mus ntxiv, thiab cov "nqaj hlau" thiab qhov cub hluav taws xob tsawg tau ua kom huv si thiab kho nyob rau ntau qhov chaw, qhov kev thov ntawm lub qhov cub hluav taws xob hauv kev lag luam steel tau nce ntxiv ceev, yog li tsav tsheb qhov kev thov rau graphite electrodes, nrog kev kwv yees txhua xyoo ntawm 600,000 tons.

Tam sim no, muaj ntau tshaj 40 qhov chaw lag luam nrog graphite electrode ntau lawm muaj peev xwm ntau tshaj 10,000 tons hauv Suav teb, nrog tag nrho cov peev txheej ntau lawm yog li 1.1 lab tons. Txawm li cas los xij, vim muaj kev cuam tshuam los ntawm cov neeg tiv thaiv ib puag ncig kev tiv thaiv xyoo no, graphite electrode ntau lawm cov chaw lag luam hauv Hebei, Shandong thiab Henan xeev nyob hauv lub xeev muaj kev txwv thiab kev tsim tawm, thiab kev tsim hluav taws xob graphite txhua xyoo kwv yees kwv yees li 500,000 tons.
"Kev ua lag luam sib txawv ntawm txog 100,000 tons tsis tuaj yeem daws teeb meem los ntawm cov tuam txhab ua kom muaj peev xwm ntau lawm." Ning Qingcai hais tias lub voj voog tsim khoom ntawm graphite electrode cov khoom lag luam feem ntau ntau tshaj li ob lossis peb hlis, thiab nrog lub voj voog rau khoom siv, nws nyuaj rau nce ntim hauv lub sijhawm luv.
Cov pa roj carbon kev lag luam tau txo qis kev tsim khoom thiab kaw, tab sis qhov kev thov ntawm cov tuam txhab steel tau nce zuj zus, uas ua rau graphite electrode los ua cov khoom lag luam nruj nyob hauv kev ua lag luam, thiab nws tus nqi tau nce txhua txoj kev. Tam sim no, txoj kev ua lag luam tus nqi tau nce 2,5 npaug piv nrog Lub Ib Hlis xyoo no. Qee cov chaw lag luam steel yuav tsum them ua ntej kom thiaj li tau txais cov khoom muag.

Raws li kev lag luam sab hauv, piv nrog moj tej tawg ua kom sov, hluav taws xob ua kom sov hlau yog lub zog ntau dua-txuag, ib puag ncig-phooj ywg thiab qis carbon. Nrog rau Tuam Tshoj nkag mus rau hauv seem ua kom qis dua qub, hluav taws xob ua kom sov hlau yuav ua tiav ntau txoj kev loj hlob. Nws kwv yees hais tias nws qhov kev faib ua feem nyob rau hauv tag nrho cov hlau tsim tawm yuav tsum nce los ntawm 6% hauv 2016 txog 30% nyob rau hauv 2030, thiab qhov kev thov rau graphite electrodes tseem loj yav tom ntej.
Tus nqi nce ntawm upstream raw cov ntaub ntawv tsis txo

Tus nqi nce ntawm graphite electrode tau kis ceev ceev rau cov kab ntawm kev lag luam. Txij thaum pib ntawm lub xyoo no, tus nqi ntawm cov khoom siv raw khoom rau cov pa roj carbon ntau lawm, xws li roj av coke, thee tar pitch, calcined coke thiab koob coke, tau nce tsis tu ncua, nrog thaj tsam nce ntxiv ntawm 100%.
Lub taub hau ntawm peb cov neeg yuav khoom tau piav nws li "nce". Raws li tus neeg saib xyuas, los ntawm kev txhawb nqa kev lag luam ua ntej kev txiav txim siab, lub tuam txhab tau coj kev ntsuas xws li kev yuav khoom ntawm tus nqi qis thiab nce cov khoom khaws cia kom paub nrog tus nqi nce thiab kom paub meej txog kev tsim khoom, tab sis cov ntse ntawm cov khoom siv raw deb tshaj qhov kev cia siab.
Ntawm qhov nce ntawm cov khoom siv raw, rab koob coke, yog cov khoom tseem ceeb ntawm graphite electrode, muaj qhov nce nqi siab tshaj plaws, nrog tus nqi siab tshaj plaws nce los ntawm 67% hauv ib hnub thiab ntau dua 300% hauv ib nrab xyoo. Nws paub tias koob coke tso nyiaj ntau dua li 70% ntawm tag nrho cov nqi ntawm graphite electrode, thiab cov khoom siv raw ntawm ultra-siab zog graphite electrode yog kiag li ntawm rab koob coke, uas noj 1.05 tons ib tuj ntawm ultra-siab zog graphite. electrode.
Koob coke kuj tseem siv tau hauv cov roj teeb lithium, kev siv hluav taws xob, kev siv dav hlau thiab lwm cov teb. Nws yog cov khoom lag luam tsis tu ncua nyob hauv tsev thiab txawv teb chaws, thiab feem ntau nws nyob ntawm kev nqa khoom hauv Suav teb, thiab nws tus nqi tseem nce siab. Txhawm rau kom paub tseeb tias cov khoom lag luam, graphite electrode cov lag luam tau tsa ib qho tom qab ib qho, uas coj mus rau qhov txuas ntxiv ntawm rab koob coke tus nqi.
Nws tau to taub tias muaj ob peb lub lag luam tsim cov koob coke hauv Tuam Tshoj, thiab cov neeg hauv kev lag luam ntseeg tias nce nqi zoo li yog lub suab tseem ceeb. Txawm hais tias lub txiaj ntsig ntawm qee cov khoom lag luam raw tau zoo heev, cov kev lag luam pheej hmoo thiab cov nqi khiav lag luam ntawm cov kev lag luam qis qis cov pa roj carbon monoxide muaj ntau ntxiv.
