Graphite electrode yog hais txog ib hom kev tiv thaiv electrode ua los ntawm roj av coke thiab rab koob coke li raw cov ntaub ntawv, thee tar pitch li binder, los ntawm raw khoom calcination, crushing thiab sib tsoo, batching, kneading, molding, roasting, impregnation, graphitization thiab mechanical processing.High-temperature graphite conductive cov ntaub ntawv yog hu ua dag graphite electrodes (hu ua graphite electrodes) kom paub qhov txawv ntawm ntuj graphite electrodes npaj los ntawm ntuj graphite.

Txij li xyoo 2022, tus nqi ntawm koob coke thiab roj av coke, cov khoom siv raw ntawm graphite electrodes, tau nce ntau zaus.Raws li lub Plaub Hlis 28, tus nqi ntawm cov roj av qis qis feem ntau tau nce los ntawm 2,700-3,680 yuan / ton piv nrog rau thaum pib ntawm lub xyoo, nrog kev nce ntxiv ntawm 57.18%.Txij li thaum xyoo tas los, cuam tshuam los ntawm kev lag luam tsis zoo electrode cov khoom lag luam, cov tuam txhab tsis zoo electrode cov khoom lag luam muaj kev xav tau ntau dua rau kev ua haujlwm graphitization thiab graphite crucibles, thiab qee lub tuam txhab graphite electrode tau tig mus rau qhov tsis zoo electrode graphitization thiab tsis zoo electrode crucibles nyob rau hauv kev cuam tshuam ntawm cov txiaj ntsig, uas ua rau muaj txiaj ntsig zoo. nyob rau hauv graphitization thiab roasting txheej txheem nyob rau hauv lub lag luam graphite electrode OEM cov kev pab yog nruj, thiab tus nqi ntawm graphite electrode graphitization nce.

Txij li thaum Lub Kaum Hli xyoo tas los, vim muaj kev txwv tsis pub muaj kev tiv thaiv ib puag ncig hauv lub caij nplooj zeeg thiab lub caij ntuj no thiab cuam tshuam ntawm kev sib kis, kev lag luam graphite electrode tau txuas ntxiv txwv.Raws li qhov kawg ntawm lub Peb Hlis, tag nrho cov kev khiav hauj lwm tus nqi ntawm graphite electrode lag luam yog kwv yees li 50%.Nyob rau hauv ob lub siab ntawm tus nqi siab thiab tsis muaj zog downstream xav tau, qee qhov chaw lag luam me thiab nruab nrab graphite electrode muaj lub zog tsim khoom tsis txaus.Nyob rau tib lub sijhawm, nyob rau hauv thawj peb lub hlis twg, Tuam Tshoj tus ntshuam ntawm koob coke poob li ntawm 70% xyoo-rau-xyoo, thiab tag nrho cov khoom lag luam graphite electrode tsis txaus.

Graphite electrode khoom yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob rau hluav taws xob ua hluav taws xob.Graphite siv nyob rau hauv steelmaking raws li ib tug electrode cov ntaub ntawv account rau txog 70% mus rau 80% ntawm tag nrho cov graphite electrode noj nyob rau hauv Tuam Tshoj.Txij li thaum hluav taws xob rauv steelmaking yog ib puag ncig tus phooj ywg ntau dua li blast furnace steelmaking, nyob rau hauv xyoo tas los no, txoj cai tau tilted rau hluav taws xob rauv steelmaking.Xyoo 2021, kuv lub teb chaws hluav taws xob cub hluav taws xob steel suav txog 15% ntawm tag nrho cov khoom siv roj av, qhov nce ntawm 5 feem pua ​​​​ntawm cov ntsiab lus piv nrog rau xyoo 2020. Qhov kev nce hauv qhov kev faib ua feem ntawm cov hluav taws xob rauv hlau ua rau qhov kev thov rau graphite electrodes.Nyob rau hauv keeb kwm yav dhau ntawm carbon neutrality, qhov kev faib ua feem ntawm hluav taws xob rauv hlau yuav nce nyob rau hauv ib tug ceev tus nqi.Xav paub ntau ntxiv txog kev lag luam graphite electrode, thov nrog peb tham kom ntxaws.
