Yuav ua li cas graphite electrode ua?

Zus tau los ntawm graphite electrodes yog aMulti - theem, siab -} cov txheej txheem kubUas hloov cov ntaub ntawv raw - masRoj av coke{{0-} rau hauv siab - zoo, hluav taws xob kos duab hluav taws xob hluav taws xob muaj peev xwm nrog cov xwm txheej huab.

Ntawm no yog ib kauj ruam - {{1} {kauj ruam txheej txheem ntawm cov graphite hluav taws xob tau tsim:

 ​1. Cov Khoom Siv Raw Xaiv​

Tus thawj raw khoom yogRoj av coke(Muab tau los ntawm cov roj ua kom zoo), qee zaum sib xyaw nrogCour tar pitchThiab lwm yam kev sib ntxiv. Rau siab dua -} qib cov hluav taws xob,Koob coke(Qhov tshwj xeeb siab -} purityum coke nrog rab koob - zoo li qauv thiab conductivity.

​Petroleum Koob Hle CokeSiv rauUHP (ultra - High High zog) Electrodes​

​Cour tar pitch→ Ua cov phau ntawv

 ​2. Sib xyaw & Taus (Kneading & Moulding)​

TusCov roj av coke yog qhov ua kom zoo, CesSib xyaw nrog cov pob zeb tawg(Lub phau ntawv tuav) los tsim homogeneous sib xyaw.

Cov sib tov no yogZomNyob rau hauv cov tshav kub muaj kev sib txuam los faib cov phau ntawv.

Lub txiaj ntsig"Cov Khoom Ntsuab"Yog moulded rau hauv qhov xav tau cov qauv hluav taws xob - feem ntauLub cylindrical-} los ntawmExtrusion lossis Kev Co Moulding​.

 ​3. Ci (carbonation)​

Ntsuab electrode yogCi hauv cov chaw ua kom sov ntawm txog 800℃- 1,200 degreeNyob rau hauv ib tug oxygen - dawb (tswj cov cua) ib puag ncig.

Tus txheej txheem noTshem cov khoom siv volatile(Zoo li ya raws thiab roj av) thiabCarbonizes lub suab binder, Tig nws mus rau hauv cov pa roj carbon.

Qhov tshwm sim yog a"Baked Carbon Electrode"Uas tau txhim kho lub zog thiab txo porosity, tab sis tseem tsis tau yooj yim graphitized.

 ​4. Impregnation (yeem tab sis nquag)​

RauNce ntom thiab txo qhov porosity, Cov khoom ci hluav taws yuav yauv musImmEGnationNrogSuab lossis cob​.

Lub electrode yog dua ci tom qab impregnation kom solorify cov khoom siv tsis tau.

Cov kauj ruam no tuaj yeem rov ua kom tau txais cov electrode cov neeg kho tshuab thiab hluav taws xob.

​5. Graphitizitization (High-} Kev Kho Mob)​

Cov kauj ruam tseem ceeb uas puv cov khoom ci ntawm cov roj teeb hluav taws xob rau hauv aMuaj tseeb Graphite Electrode electrodeYogDuab​.

Lub ci thiab muaj peev xwm impregnated electrode yogRhuab rau kev kub siab heev (2,500℃- 3,000 degree)Hauv ibAcheson rauv taws lossis hauv ib qho tshwj xeeb graphitization rauvKev sivHluav Taws Xob Ua Cua Sov Cua Sov​.

Nyob rau hauv cov mob no, cov pa roj atoms rearrange rau hauv lubCrystalline Graphite Qauv, Uas muaj:

​Zoo hluav taws xob conductivity​

​Siab siab thermal conductivity​

​Lub zog siab thiab ruaj khov ntawm huab cua sov heev​

​6. Machining & Tess​

Lub graphitized electrode yog cesMachined los kho qhov ntev(Txoj kab uas hla, ntev, xov sib txuas, thiab lwm yam) Siv cov cuab yeej pob zeb diamond lossis CNC tshuab.

Xov, pob qij txha, thiab lwm cov nta tau ntxiv rau kev tso cai rau ntau cov electrodes yuavSib dhos thaum kawg - rau -} xausHauv hluav taws xob arc rauv.

 ​7. Kev Kuaj Zoo & Kev Tawm Tshiab​

Ua tiav graphite electrodes raug sim rau:

​Hluav taws xob tiv thaiv hluav taws xob​

​Ceev​

​Neeg Kho Tshuab Muaj Zog​

​Kev tsim​

Raws li cov khoom no, lawv tau raug cais rau hauv cov qib sib txawv:

​RP (ib txwm muaj zog)​

​HP (High Fiber)​

​UHP (ultra - lub zog siab){{0 {}} Qhov kev coj ua tshaj plaws thiab muaj txiaj ntsig, siv hauv EAF tam sim no

 

​Graphite electrodes yog ua los ntawm kev sib xyaw roj coke nrog binder, kev ua kom haum nws, thiab tom qab ntawd graphitizing nws ntawm ultra {{0} high kub. Cov khoom kawg yog qhov ua tau zoo, ruaj, thiab cov ruaj khov electrode siv feem ntau hauv steelmaking thiab lwm yam siab {2} kev siv hluav taws xob.

Lus Kawg:

Yam	Tseem Ceeb Takaway
​Vim li cas graphite yog ib qho zoo electrode?​	Vim tias nws ua hluav taws xob, tawm tsam huab cua sov heev, tsis hnov ​​zoo nrog lwm cov ntaub ntawv, thiab tseem muaj zog txawm tias nyob ntawm qhov kub.
​Nws ua li cas?​	Los ntawm cov txheej txheem nyuaj uas cuam tshuam nrog kev sib xyaw roj av nrog cov hlua khi, sib sau, kev siv tau), graphitizing ntawm qhov kub heev, thiab cov khoom siv ntsuas ntshav.

Ob qho tib siCov Khoom SivThiab tusCov txheej txheem tsim khoomNtawm graphite elecodes pab txhawb lawv lub luag haujlwm tseem ceeb hauv kev lag luam zoo liSteel qhuav, electrolysis, thiab siab - lub zog hluav taws xob​.
