Graphite electrode hais txog roj av coke, koob coke li raw khoom, thee tar rau adhesives, tom qab raw khoom calcined, tawg sib tsoo, sib tov, kneading, molding, calcination, impregnation, graphite thiab mechanical processing thiab ua los ntawm ib hom kub kub kuj ntawm. graphite conductive khoom, hu ua dag graphite electrode (tom qab no hu ua graphite electrode), kom paub qhov txawv ntawm lub ntuj graphite li raw khoom npaj ntawm ntuj graphite electrode. Raws li nws cov txiaj ntsig zoo, nws tuaj yeem muab faib ua lub zog zoo tib yam graphite electrode, siab zog graphite electrode thiab ultra-siab zog graphite electrode.
Lub zog hluav taws xob graphite electrode yog ua los ntawm cov roj av coke zoo (lossis qib qis koob coke) ntau lawm, qee zaum lub cev electrode yuav tsum tau impregnated, nws lub cev thiab cov khoom siv hluav taws xob siab dua li cov hluav taws xob zoo tib yam graphite electrode, xws li tsis tshua muaj zog, tso cai rau lub zog loj dua. tam sim no ceev.
Lub zog siab graphite electrode tso cai rau kev siv tam sim no ceev ntawm 18 ~ 25A / cm2 graphite electrode, feem ntau yog siv rau hauv high-power arc rauv steel ua.
Hluav taws xob rauv steelmaking yog cov neeg siv loj ntawm graphite electrodes. Cov zis ntawm eAF steel nyob rau hauv Tuam Tshoj suav txog li 18% ntawm cov khoom siv roj av, thiab cov graphite electrode siv hauv steelmaking nyiaj rau 70% ~ 80% ntawm tag nrho cov nyiaj ntawm graphite electrode. Hluav taws xob rauv steelmaking yog siv cov graphite electrode rau hauv lub cub tawg tam sim no, siv cov hluav taws xob hnyav thiab nqi nruab nrab ntawm cov arc generated los ntawm cov kub kub qhov chaw rau smelting.
-arc rauv yog tsuas yog siv nyob rau hauv zus tau tej cov daj phosphorus thiab silicon, thiab lwm yam., nws cov yam ntxwv yog lub qis ib feem ntawm cov conductive electrode faus nyob rau hauv lub cub tawg nqi, arc tsim nyob rau hauv cov ntaub ntawv txheej, thiab siv lub cub tawg them nws tus kheej los ntawm cov kuj. ntawm cov hluav taws xob hluav taws xob rau cov hluav taws xob hluav taws xob hluav taws xob, ib qho ntawm qhov siab tam sim no yuav tsum tau -arc rauv xav tau graphite electrode, xws li silicon 1 t ib qho khoom siv rau graphite electrode yog li 100 kg, txog 40kg ntawm graphite electrode yog xav tau los tsim 1t. daj phosphorus.
Lub graphitization rauv rau zus tau tej cov khoom graphite, lub melting rauv rau melting iav thiab hluav taws xob rauv rau zus tau tej cov silicon carbide muaj nyob rau hauv lub qhov hluav taws xob kuj. Cov khoom nyob rau hauv lub cub tawg yog ob qho tib si cov cua kub tsis kam thiab cov khoom cua sov. Feem ntau, cov conductive graphite electrode yog embedded nyob rau hauv lub cub tawg phab ntsa ntawm qhov kawg ntawm lub qhov hluav taws xob kuj, thiab cov graphite electrode yog siv rau kev noj tsis tu ncua ntawm no.
Cov graphite electrode dawb paug kuj tseem siv rau kev ua ntau yam crucible, pwm, nkoj thiab cua sov lub cev thiab lwm yam khoom tshwj xeeb zoo li graphite. Piv txwv li, hauv kev lag luam quartz iav, 10T ntawm graphite electrode billet yog xav tau rau txhua 1T ntawm hluav taws xob fuse tube ntau lawm; 100kg ntawm graphite electrode billet yog xav tau los tsim 1t quartz cib.
Txij li thaum pib ntawm lub quarter thib plaub ntawm xyoo 2016, nrog rau kev txhawb nqa ntawm kev hloov pauv ntawm cov khoom siv hauv kev lag luam hlau thiab hlau, kev sib tsoo ntawm cov hlau hauv pem teb tau dhau los ua qhov tseem ceeb tshaj plaws hauv kev tshem tawm cov peev txheej rov qab. Thaum Lub Ib Hlis 10, 2017, tus lwm thawj coj ntawm National Development thiab Reform Commission tau hais nyob rau hauv 2017 Council lub rooj sib tham ntawm CISA tias tag nrho cov tuav hauv pem teb yuav tsum tau muab tshem tawm ua ntej Lub Rau Hli 30, 2017. Hauv 2017, Tuam Tshoj tag nrho cov peev txheej ntawm eAF steel yog txog 120 lab tons. , ntawm 86.6 lab tons tau tsim tawm thiab 15.6 lab tons tau tawm ntawm kev tsim khoom. Raws li qhov kawg ntawm Lub Kaum Hli 2017, lub peev xwm tsim khoom ntawm eAF yog kwv yees li 26.5 lab tons, ntawm 30% tau rov pib dua. Kev cuam tshuam los ntawm kev txo qis ntawm qhov nruab nrab zaus cua sov, hluav taws xob rauv hlau tau pib ua haujlwm, thiab cov txiaj ntsig kev lag luam ntawm hluav taws xob rauv hlau yog qhov tseem ceeb. Hluav taws xob rauv hlau muaj qhov xav tau zoo rau lub zog siab thiab lub zog ultra-siab graphite electrode, thiab kev yuav khoom siab.
Hauv xyoo 2017, tus nqi hauv tsev ntawm graphite electrode tau nce siab, thiab kev thov txawv teb chaws tau nce. Ob lub lag luam hauv tsev thiab txawv teb chaws rov qab los rau kev vam meej. Hauv Suav teb, vim qhov kev tshem tawm ntawm "pem teb steel", qhov nce ntawm hluav taws xob arc rauv muaj peev xwm, kev tiv thaiv ib puag ncig ntawm cov tuam txhab lag luam thiab lwm yam, cov nqi hluav taws xob hluav taws xob hauv tsev tau nce siab hauv xyoo 2017, qhia tias kev lag luam hauv tsev graphite electrode nyob rau hauv khoom tsis txaus. Nyob rau tib lub sijhawm, Tuam Tshoj txoj kev loj hlob ntawm graphite electrode qhia tau hais tias txawv teb chaws graphite electrode xav tau muaj zog. Hauv tsev thiab txawv teb chaws tau pom muaj zog thov rau graphite electrodes, kev lag luam tseem nyob rau hauv cov khoom tsis txaus.
Yog li ntawd, kev nqis peev attraction ntawm siab zog graphite electrode kev lag luam tseem muaj zog.
Nrog rau txoj kev loj hlob ntawm lub ntiaj teb no hlau thiab hlau kev lag luam, hluav taws xob arc rauv maj mam mus rau qhov loj, ultra-siab zog thiab lub computer tsis siv neeg tswj thiab lwm yam kev loj hlob, kev siv ntawm high-power hluav taws xob arc rauv yog nce, txhawb daim ntawv thov ntawm high-power graphite electrode. .
Piv nrog rau Tebchaws Meskas, Tebchaws Europe, Nyiv thiab lwm lub tebchaws thiab cheeb tsam, Tuam Tshoj txoj kev lag luam muaj zog graphite electrode pib lig, feem ntau vam khom rau kev xa khoom thaum ntxov, kev tsim cov khoom siv hluav taws xob siab graphite electrode yog deb ntawm qhov kev thov. Tsav los ntawm txoj kev loj hlob ntawm hlau thiab hlau kev lag luam thiab kev lag luam thev naus laus zis, Tuam Tshoj tau maj mam rhuav tshem cov thev naus laus zis ntawm cov teb chaws txawv teb chaws, thiab cov peev txheej tsim hluav taws xob muaj zog graphite electrode tau nce, thiab cov khoom lag luam zoo kuj tau txhim kho sai heev. Tam sim no, lub zog hluav taws xob siab graphite electrode uas tsim nyob rau hauv Suav teb tau ua tiav cov txiaj ntsig zoo hauv cov hluav taws xob arc rauv loj, thiab tag nrho cov kev ua tau zoo ntawm cov khoom tuaj yeem ncav cuag qib thoob ntiaj teb. Tuam Tshoj lub zog siab graphite electrode cov khoom lag luam tsis tsuas yog muab cov khoom lag luam hauv tsev, tab sis kuj muaj ntau cov khoom xa tawm mus rau txawv teb chaws, qhov kev thov rau cov khoom siv txawv teb chaws yog tsawg dua.
Txoj kev loj hlob ntawm lub cub tawg steelmaking rau siab zog yog ib qho tseem ceeb ntawm txoj kev loj hlob ntawm hluav taws xob rauv steelmaking kev lag luam. Nyob rau hauv lub neej yav tom ntej, cov zis ntawm high-power hluav taws xob rauv steelmaking yuav nce, thiab nws qhov kev thov rau siab zog graphite electrode kuj yuav nce, txhawb zus tau tej cov high-power graphite electrode nyob rau hauv Tuam Tshoj. Cov tuam txhab muaj zog graphite electrode hauv tsev tuaj yeem txuas ntxiv cov khoom lag luam, ua tiav kev tshawb fawb thiab kev tsim cov khoom siv raw, thiab tsim cov khoom siv, uas tuaj yeem txo cov nqi lag luam thiab txhim kho kev lag luam cov txiaj ntsig.
