Koob coke muaj ib rab koob zoo li tus qauv thiab yog ua los ntawm cov roj slurry los ntawm refineries los yog thee tar pitch. Nws yog cov khoom siv tseem ceeb rau kev ua graphite electrodes uas yog siv rau hauv kev tsim cov hlau siv hluav taws xob arc rauv (EAF). Cov koob tshuaj coke no suav nrog kev muag khoom los ntawm kev lag luam graphite, kev lag luam roj teeb, thiab lwm yam. Peb qhov kev soj ntsuam kuj tseem suav txog kev muag cov koob coke hauv APAC, Europe, North America, South America, thiab MEA. Hauv 2018, ntu kev lag luam graphite tau muaj kev lag luam tseem ceeb, thiab cov qauv no yuav tsum tau txuas ntxiv mus rau lub sijhawm kwv yees. Cov yam ntxwv xws li nce kev thov rau graphite electrodes rau EAF txoj kev ntawm cov hlau ntau lawm yuav ua lub luag haujlwm tseem ceeb hauv ntu kev lag luam graphite kom tuav nws txoj haujlwm ua lag luam. Tsis tas li ntawd, peb daim ntawv tshaj tawm thoob ntiaj teb koob coke ua lag luam saib cov yam ntxwv xws li kev nce hauv cov roj refining muaj peev xwm, nce hauv kev saws tsheb ntsuab, nce kev thov rau UHP graphite electrodes. Txawm li cas los xij, kev nthuav dav lithium kev xav tau-kev sib txawv cov kev sib tw uas tau ntsib hauv kev nqis peev hauv kev lag luam thee vim yog cov cai tiv thaiv cov pa phem, kev hloov pauv hauv cov roj av thiab cov nqi hluav taws xob tuaj yeem cuam tshuam kev loj hlob ntawm koob coke kev lag luam nyob rau lub sijhawm kwv yees.
Ntiaj teb no koob Coke Market: Txheej txheem cej luam
Kev thov ntau ntxiv rau UHP graphite electrodes
Graphite electrodes yog siv rau hauv daim ntawv thov, xws li submerged arc furnaces thiab ladle furnaces rau zus tau tej cov hlau, cov ntaub ntawv uas tsis yog-hlau, thiab hlau. Lawv kuj tseem siv feem ntau hauv EAFs rau kev tsim cov hlau. Graphite electrodes tuaj yeem tsim tau siv roj av coke lossis rab koob coke. Graphite electrodes tau muab faib ua lub zog tsis tu ncua, lub zog siab, lub zog siab, thiab UHP raws li qhov tsis zoo xws li kev tiv thaiv, hluav taws xob conductivity, thermal conductivity, tsis kam oxidation thiab thermal shock, thiab txhua yam muaj zog. Tawm ntawm txhua hom graphite electrodes. UHP graphite electrodes tau txais kev saib xyuas hauv kev lag luam steel. Qhov kev thov no rau UHP electrodes yuav ua rau nthuav dav thoob ntiaj teb koob coke kev lag luam ntawm CAGR ntawm 6% thaum lub sijhawm kwv yees.
Qhov tshwm sim ntawm ntsuab hlau
Lub emission ntawm CO2 yog ib qho teeb meem loj uas tau ntsib los ntawm kev lag luam steel thoob ntiaj teb. Txhawm rau daws qhov teeb meem, ntau yam kev tshawb fawb thiab kev tsim kho (R&D) tau ua. Cov haujlwm R&D no tau coj mus rau qhov tshwm sim ntawm cov hlau ntsuab. Cov kws tshawb fawb tau pom cov txheej txheem ua hlau tshiab uas tuaj yeem tshem tawm CO2 emissions tag nrho. Nyob rau hauv cov txheej txheem steel ua ib txwm, thaum lub sij hawm steel ntau lawm, cov pa taws ntau, carbon, thiab belching nplaim raug tso tawm. Cov txheej txheem ua hlau ib txwm tso tawm CO2 ob zaug ntawm qhov hnyav ntawm cov hlau. Txawm li cas los xij, cov txheej txheem tshiab tuaj yeem ua tiav steel-ua nrog xoom emissions. Pulverized thee txhaj thiab carbon capture thiab cia (CCS) thev naus laus zis yog ntawm lawv. Txoj kev loj hlob no xav tias yuav muaj kev cuam tshuam zoo rau tag nrho kev lag luam kev loj hlob.
Kev sib tw toj roob hauv pes
Nrog rau lub xub ntiag ntawm ob peb tug loj players, lub ntiaj teb no koob coke kev lag luam yog concentrated. Qhov kev ntsuam xyuas tus neeg muag khoom muaj zog no yog tsim los pab cov neeg siv khoom txhim kho lawv txoj kev lag luam, thiab raws li qhov no, daim ntawv tshaj tawm no muab cov ncauj lus kom ntxaws ntawm ntau tus kws tshaj lij coke manufacturers, suav nrog C-Chem Co. Ltd., GrafTech International Ltd., Mitsubishi Chemical. Holdings Corp., Phillips 66 Co., Sojitz Corp., thiab Sumitomo Corp.
Tsis tas li ntawd, koob tshuaj coke kev lag luam daim ntawv tshaj tawm suav nrog cov ntaub ntawv hais txog cov qauv thiab cov kev sib tw uas yuav cuam tshuam rau kev lag luam loj hlob. Qhov no yog los pab cov tuam txhab lag luam tawm tswv yim thiab siv zog ntawm txhua txoj hauv kev loj hlob yav tom ntej.
