Kev ua lag luam rau graphite electrode tau cia siab tias yuav sau npe CAGR ntau dua 9% thaum lub sijhawm kwv yees. Cov khoom siv tseem ceeb siv rau kev tsim cov graphite electrode yog koob coke (xws li roj av los yog thee-based).
Kev nce qib ntawm cov hlau thiab hlau nyob rau hauv cov teb chaws tshiab, nce cov khoom seem ntawm cov hlau hauv Suav teb yog li ua rau kev siv hluav taws xob arc rauv yuav tsum tsav qhov kev thov rau kev lag luam thaum lub sijhawm kwv yees.
Soaring tus nqi ntawm koob coke uas ua rau cov khoom nruj nreem ntawm lwm yam kev txwv xws li kev loj hlob ntawm UHP graphite electrode nyob rau hauv Tuam Tshoj thiab kev koom ua ke ntawm graphite electrode kev lag luam yuav cuam tshuam rau kev lag luam kev loj hlob.
Kev nce qib ntawm cov hlau los ntawm hluav taws xob arc rauv tshuab hauv Suav teb yuav tsum ua raws li lub sijhawm rau kev lag luam yav tom ntej.
Kev Lag Luam Tseem Ceeb
Txhim kho cov hlau los ntawm hluav taws xob Arc rauv Technology
- Hluav taws xob arc rauv siv steel seem, DRI, HBI (kub briquetted hlau, uas yog compacted DRI), los yog npua hlau nyob rau hauv daim ntawv, thiab melts lawv los ua hlau. Hauv txoj kev EAF, hluav taws xob muab lub zog los yaj cov khoom noj.
- Graphite electrode feem ntau yog siv nyob rau hauv hluav taws xob arc rauv (EAF) steelmaking txheej txheem, kom yaj hlau seem. Electrodes yog tsim los ntawm graphite vim nws muaj peev xwm tiv taus qhov kub thiab txias. Hauv EAF, qhov ntxeev ntawm lub electrode tuaj yeem ncav cuag 3,000 Fahrenheit, uas yog ib nrab ntawm qhov kub ntawm lub hnub. Qhov loj ntawm electrodes txawv dav, los ntawm 75mm nyob rau hauv txoj kab uas hla, kom loj li 750mm nyob rau hauv lub cheeb, thiab mus txog rau 2,800mm nyob rau hauv ntev.
- Tus nqi nce siab ntawm graphite electrodes thawb EAF mills cov nqi. Qhov nruab nrab EAF yog kwv yees siv kwv yees li 1.7 kg ntawm graphite electrodes los tsim ib metric tons ntawm hlau.
- Tus nqi nce siab vim yog kev lag luam sib koom ua ke, thoob ntiaj teb, muaj peev xwm kaw hauv Suav teb, ua raws li kev tswj hwm ib puag ncig, thiab kev loj hlob ntawm EAF ntau lawm, thoob ntiaj teb. Qhov no yog kwv yees nce tus nqi tsim khoom ntawm EAF los ntawm 1-5%, nyob ntawm kev ua haujlwm ntawm zeb, thiab qhov no yuav txwv tsis pub cov hlau ntau lawm, vim tias tsis muaj kev hloov pauv rau graphite electrode hauv EAF cov haujlwm.
- Tsis tas li ntawd, Tuam Tshoj txoj cai los daws cov pa phem tau ntxiv dag zog los ntawm cov khoom lag luam muaj zog rau, tsis yog tsuas yog cov hlau, tab sis kuj tseem siv cov thee, zinc, thiab lwm yam uas tsim cov pa phem. Yog li ntawd, Suav steel ntau lawm tau poob qis ntau xyoo dhau los. Txawm li cas los xij, qhov no yuav tsum muaj kev cuam tshuam zoo rau cov nqi steel thiab steel mills hauv cheeb tsam, kom tau txais txiaj ntsig zoo dua.
- Txhua yam uas tau hais tseg saum toj no, yuav tsum tau tsav lub lag luam graphite electrode thaum lub sijhawm kwv yees.
Asia-Pacific cheeb tsam los ua lag luam
- Asia-Pacific cheeb tsam dominated lub ntiaj teb no ua lag luam qhia. Tuam Tshoj occupies loj tshaj plaws nyob rau hauv cov nqe lus ntawm kev noj thiab ntau lawm muaj peev xwm ntawm graphite electrodes nyob rau hauv lub ntiaj teb no scenario.
- Txoj cai tshiab txoj cai tswjfwm hauv Beijing thiab lwm lub xeev loj hauv lub tebchaws yuam cov neeg tsim khoom hlau kaw lub peev xwm ntawm 1.25 lab tons ntawm cov hlau uas tsim los ntawm ib puag ncig kev puas tsuaj thiaj li tsim tau lub peev xwm tshiab ntawm 1 lab tons ntawm hlau. Cov kev cai zoo li no tau txhawb kev hloov pauv ntawm cov tuam txhab los ntawm cov txheej txheem ntawm cov khoom siv hlau mus rau EAF txoj kev.
- Kev loj hlob ntawm cov tsheb loj, nrog rau kev nthuav dav hauv kev tsim kho vaj tse, yuav tsum txhawb nqa cov kev thov hauv tsev rau cov hlau tsis muaj hlau thiab hlau, uas yog qhov zoo rau kev loj hlob ntawm graphite electrode xav tau nyob rau xyoo tom ntej.
- Tam sim no muaj peev xwm ntawm UHP graphite electrodes nyob rau hauv Suav teb yog nyob ib ncig ntawm 50 txhiab metric tuj ib xyoos twg. Qhov kev thov rau UHP electrodes nyob rau hauv Tuam Tshoj kuj tseem xav kom pom qhov kev loj hlob tseem ceeb nyob rau hauv lub sij hawm ntev thiab muaj peev xwm ntxiv ntawm ntau tshaj 50 txhiab metric ton ntawm UHP graphite electrodes yog cia siab tias yuav pom los ntawm cov theem tom ntej ntawm lub sijhawm kwv yees.
- Tag nrho cov saum toj no-hais yam tseem ceeb, nyob rau hauv lem, yuav tsum tau nce qhov kev thov rau graphite electrode nyob rau hauv lub cheeb tsam thaum lub sij hawm kwv yees.
