Tam sim no, cov nqi qis-sulfur coke thiab thee tar pitch nyob rau hauv upstream ntawm graphite electrodes tau nce me ntsis, thiab tus nqi ntawm koob coke tseem nyob rau theem siab.Superimposed ntawm cov yam ntxwv ntawm kev nce nqi hluav taws xob, cov nqi tsim khoom ntawm graphite electrodes tseem siab.Hauv qab ntawm graphite electrodes, cov nqi steel hauv tsev tau poob qis, suav nrog kev txwv ib puag ncig kev tiv thaiv nyob rau lub caij nplooj zeeg thiab lub caij ntuj no nyob rau sab qaum teb, qhov kev thov qis qis tau txuas ntxiv mus, cov hlau mills tau nquag txwv kev tsim khoom thiab tso tseg, thiab pib ua haujlwm tsis muaj zog. kev ua haujlwm.Graphite electrode kev ua lag luam xa khoom tseem yog feem ntau raws li kev ua raws li kev txiav txim ua ntej.Graphite electrode tuam txhab uas muag tsis muaj cov khoom muag siab.Kev txiav txim tshiab hauv kev lag luam graphite electrode raug txwv, tab sis cov khoom siv yog nruj tag nrho, thiab cov nqi lag luam graphite electrode nyob ruaj khov.
Lub lim tiam no, kev ua lag luam graphite electrode hauv tsev muaj lub zog tos-thiab-pom huab cua.Txog rau thaum xaus ntawm lub xyoo, kev khiav hauj lwm ntawm steel mills nyob rau sab qaum teb cheeb tsam tau poob vim muaj kev cuam tshuam rau lub caij nyoog, thaum cov khoom tsim tawm ntawm thaj av yav qab teb tseem raug txwv vim muaj kev txwv fais fab.Cov zis yog qis dua qub.Piv nrog rau tib lub sijhawm, qhov kev thov rau graphite electrodes tau poob qis me ntsis.Nws tseem tsuas yog yuav khoom ntawm kev thov.
Hais txog kev xa tawm: Tsis ntev los no, muaj ntau cov lus nug txawv teb chaws, tab sis feem ntau ntawm lawv yog thawj peb lub hlis twg ntawm xyoo tom ntej.Yog li ntawd, tsis muaj ntau qhov kev txiav txim tiag tiag, thiab lawv feem ntau tos-thiab-pom.Hauv kev lag luam hauv tsev lub lim tiam no, vim tias tus nqi poob qis ntawm qee cov nroj tsuag petcoke thaum ntxov, lub hlwb ntawm qee cov tub lag luam hloov pauv me ntsis, thaum lwm cov tuam txhab graphite electrode tseem tsom rau kev ruaj ntseg.Txog rau thaum xaus ntawm lub xyoo, qee cov tuam txhab lag luam thim nyiaj thiab kev ua haujlwm khiav haujlwm.Yog li ntawd, nws yog ib txwm ua rau graphite electrode tus nqi hloov pauv me ntsis.
Cov tuam txhab loj thoob ntiaj teb graphite electrode suav nrog GrafTech International, Showa Denko KK, Tokai Carbon, Fangda Carbon New Material Technology Co., Ltd., Graphite India Limited (GIL), thiab lwm yam. Lub ntiaj teb sab saum toj ob lub ntiaj teb graphite electrode manufacturers ua ke rau ntau tshaj 35. % Kev lag luam feem.Asia-Pacific cheeb tsam tam sim no yog lub ntiaj teb loj tshaj plaws graphite electrode kev lag luam, suav txog kwv yees li 48% ntawm kev ua lag luam, tom qab ntawd Europe thiab North America.
Xyoo 2020, kev lag luam thoob ntiaj teb graphite electrode tau mus txog 36.9 billion yuan thiab xav tias yuav ncav cuag 47.5 billion yuan hauv 2027, nrog rau kev loj hlob txhua xyoo (CAGR) ntawm 3.5%.
