Luv luv Introduction rau Graphite Electrode
Graphite electrodes feem ntau yog siv nyob rau hauv hluav taws xob arc rauv. Tam sim no lawv tsuas yog cov khoom lag luam uas muaj cov khoom siv hluav taws xob siab thiab muaj peev xwm txhawb nqa cov cua sov uas tsim los hauv EAF. Graphite electrodes kuj tseem siv los ua kom zoo hlau hauv cov ladle furnaces thiab hauv lwm cov txheej txheem smelting. Graphite electrodes tau muab faib ua 4 hom: RP Graphite electrodes, HP Graphite electrodes, SHP Graphite electrodes, thiab UHP Graphite electrodes.
Yooj yim rau txheej txheem
Qhov nyuaj ntawm cov pwm geometries thiab kev sib txawv ntawm cov khoom siv tau ua rau muaj kev xav tau ntau dua rau kev tso tawm qhov tseeb ntawm lub tshuab hluav taws xob. Qhov zoo ntawm graphite electrodes yog kev ua haujlwm yooj yim dua, uas txhais tau hais tias lawv muaj kev tshem tawm cov machining siab thiab qis graphite poob. Yog li ntawd, qee lub tshuab EDM tau tso tseg tooj liab electrodes thiab hloov mus rau graphite electrodes. Tsis tas li ntawd, qee cov electrodes nrog cov duab tshwj xeeb tsis tuaj yeem ua los ntawm tooj liab thiab tooj liab hnyav dua thiab tsis haum rau kev ua cov electrodes loj, tab sis graphite yooj yim dua rau cov duab. Cov xwm txheej no tau ua rau qee lub tshuab hluav taws xob siv graphite electrodes.
Ceev ceev ceev
Graphite electrodes yooj yim rau kev ua haujlwm thiab kev ua haujlwm nrawm nrawm dua li tooj liab electrodes. Piv txwv li, cov txheej txheem milling yog siv los ua cov graphite, uas yog 2 mus rau 3 lub sij hawm sai dua li lwm cov hlau ua thiab tsis tas yuav tsum tau ua phau ntawv ntxiv, thaum tooj liab electrodes xav tau phau ntawv sib tsoo. Ib yam li ntawd, yog tias lub chaw ua haujlwm siab ceev graphite siv los tsim cov khoom siv hluav taws xob, qhov ceev yuav nrawm dua, kev ua haujlwm yuav siab dua, thiab yuav tsis muaj teeb meem plua plav. Thaum cov txheej txheem machining no, xaiv cov cuab yeej thiab graphite nrog qhov tsim nyog hardness tuaj yeem txo cov cuab yeej hnav thiab tooj liab tawg. Yog tias peb tshwj xeeb piv rau lub sijhawm milling ntawm graphite electrodes thiab tooj liab electrodes, graphite electrodes yog 67% sai dua tooj liab electrodes. Nyob rau hauv dav dav machining, machining nrog graphite electrodes yog 58% sai dua tooj liab electrodes. Hauv txoj kev no, lub sijhawm ua haujlwm tau txo qis, thiab cov nqi tsim khoom kuj raug txo.
Ib yam nyiaj pub dawb
Graphite electrodes yog tsim txawv dua li cov qauv tooj liab electrodes. Ntau lub tuam txhab pwm feem ntau muaj cov nyiaj sib txawv rau kev ua haujlwm ntxhib thiab ua tiav ntawm tooj liab electrodes, thaum graphite electrodes siv yuav luag tib yam nyiaj pub dawb, uas txo cov naj npawb ntawm CAD / CAM thiab cov tshuab ua haujlwm. Vim li no ib leeg xwb, graphite electrode yog txaus los txhim kho qhov tseeb ntawm pwm kab noj hniav kom ntau npaum li cas.
Lwm yam nta
Niaj hnub no, qee lub tshuab EDM siv graphite rau electrode discharge machining, uas tshem tawm cov txheej txheem ntawm pwm kab noj hniav polishing thiab tshuaj polishing, tab sis tseem tuaj yeem ua tiav qhov kev xav tau ntawm qhov kawg. Tsis tas li ntawd, graphite muab faib ua ntau qib. Tsuas yog los ntawm kev siv cov qib uas tsim nyog ntawm graphite thiab cov hluav taws xob paug rau cov ntawv thov tshwj xeeb tuaj yeem ua tiav cov txiaj ntsig zoo tshaj plaws. Yog hais tias tus neeg teb xov tooj siv tib yam tsis xws li tooj liab electrode ntawm lub tshuab hluav taws xob siv graphite electrodes, ces qhov tshwm sim yog twv yuav raug hu poob siab. Yog tias cov khoom siv ntawm cov electrode yuav tsum tau tswj nruj me ntsis, cov graphite electrode tuaj yeem raug teeb tsa mus rau lub xeev tsis poob (tsawg dua 1%) thaum lub sijhawm ua haujlwm ntxhib, tab sis tooj liab electrode tsis tuaj yeem.
Hom ntawm Graphite Electrode
SDGE
Muaj ob hom graphite electrodes muaj. Ib hom hu ua "SDGE," uas sawv cev rau me me graphite electrodes. Cov electrodes no feem ntau yog siv rau melting seem hlau thiab lwm yam ntaub ntawv raw thiab yog siv nyob rau hauv Electric Arc Furnaces (EAF). Cov electrodes muaj tam sim no uas tsim ib qho arc ntawm cov electrode thiab cov khoom siv raw, ua rau nws yaj.
LDGE
Lwm hom electrode yog "LDGE" lossis loj graphite electrode. Cov hom graphite electrodes no feem ntau yog siv rau cov hlau yaj hauv EAFs loj heev uas yuav tsum tau siv qhov kub thiab txias heev. Tsis zoo li cov kab hluav taws xob me me, nws lub peev xwm nqa tau li ntawm 15, 000 txog 70, 000 amps, tam sim no muaj peev xwm ntawm LDGEs txawv ntawm 60, 000 mus rau 160, 000 cov amps.
SDGE vs LDGE
SDGEs feem ntau yog tsim los ntawm roj av coke, tsis hais qib twg. Qee cov SDGEs yog tsim los nrog qib siab coke, lwm tus nrog qib qis coke. Qhov tseeb, qee qhov SDGE yog qhov sib xyaw ntawm ntau qib sib txawv. LDGEs ntawm qhov tod tes, feem ntau yog tsim nrog hwm, 100% qib siab koob coke.
Kev tsim cov txheej txheem ntawm Graphite Electrode
Yog tias koj nyob hauv kev lag luam rau cov khoom siv hluav taws xob zoo graphite, nws yog ib qho tseem ceeb kom nkag siab tias lawv tsim tau li cas. Graphite electrodes yog ib qho tseem ceeb hauv kev lag luam steelmaking, thiab lawv ua lub luag haujlwm tseem ceeb hauv kev tsim cov hlau.
Raw Materials siv nyob rau hauv Graphite Electrode Manufacturing
Thawj kauj ruam hauv graphite electrode manufacturing txheej txheem yog nrhiav cov ntaub ntawv raw. Graphite electrodes yog tsim los ntawm kev sib xyaw ntawm roj av coke, pitch coke, thiab thee tar pitch. Cov ntaub ntawv no tau ua tib zoo xaiv rau lawv cov purity thiab sib xws. Petroleum coke yog ib qho khoom siv los ntawm cov txheej txheem roj refining, thaum lub suab coke yog cov khoom siv los ntawm kev tsim cov coke. Coal tar pitch yog tau los ntawm distillation ntawm thee tar. Kev sib xyaw ntawm cov ntaub ntawv no tau ua tib zoo tsim kom ua tiav cov khoom xav tau hauv cov khoom kawg.
Mixing thiab Extruding
Thaum cov khoom siv raw tau txais, lawv tau muab sib xyaw ua ke hauv ib lub tshuab tov khoom loj. Cov sib tov yog ces extruded mus rau hauv lub xav tau zoo thiab loj siv ib tug high-pressure extruder. Cov khoom extruded ces txiav mus rau qhov ntev yuav tsum tau.
Ci
Cov kauj ruam tom ntej hauv kev tsim khoom yog ci. Cov khoom siv extruded yog muab tso rau hauv qhov cub ci thiab ua kom sov rau qhov kub siab heev (txog 3000 degrees Celsius) hauv qhov chaw tsis muaj oxygen. Cov txheej txheem no hu ua graphitization thiab yog dab tsi muab cov graphite electrode nws cov khoom tshwj xeeb.
Tshuab dhos
Thaum cov txheej txheem ci tiav, cov graphite electrodes yog machined rau lawv cov duab kawg thiab loj. Cov txheej txheem no yuav tsum muaj cov cuab yeej precision thiab cov neeg ua haujlwm txawj ntse.
Kev Tswj Xyuas Zoo
Kev tswj kom zoo yog ib feem tseem ceeb ntawm graphite electrode manufacturing txheej txheem. Txhua pawg ntawm cov electrodes yog ua tib zoo tshuaj xyuas kom ntseeg tau tias lawv ua tau raws li cov qauv tsim nyog rau kev ua tau zoo thiab sib xws. Qhov no suav nrog kev ntsuas qhov ntom ntom, lub zog, thiab hluav taws xob conductivity.
Hom Rauv
Thawj qhov uas koj yuav tsum xav txog thaum xaiv qhov zoo graphite electrode yog hom rauv koj siv. Muaj ob hom hluav taws xob arc rauv: DC thiab AC. DC furnaces yog siv rau hlau thiab lwm yam ferrous hlau ntau lawm, thaum AC furnaces yog siv rau non-ferrous hlau ntau lawm xws li txhuas, tooj liab, thiab zinc. DC rauv hluav taws xob hluav taws xob yog ua los ntawm cov khoom siv hluav taws xob zoo thiab muaj cov hluav taws xob qis dua li AC rauv hluav taws xob electrodes, uas yog ua los ntawm cov graphite qis dua.
Zoo
Qhov zoo ntawm graphite electrodes yog qhov tseem ceeb rau lawv cov kev ua tau zoo, durability, thiab kev ntseeg tau.
