Fais arc rauv (EAF) tau hloov kho cov kev lag luam steelmaking, muab cov kev siv hluav taws xob ntau thiab ib puag ncig cov hluav taws kub ua kom tawg. Central rau kev ua haujlwm ntawm EAF yog cov graphite electrodes, uas pab txhawb rau lub tshuab hluav taws xob tsim nyog rau melting seem ntawm steel thiab lwm cov ntaub ntawv raw. Txawm li cas los xij, kev ua tau zoo thiab kev ua haujlwm ntev ntawm cov hluav taws xob hluav taws xob hnyav nyob ntawm qhov zoo ntawm cov pob qij txha txuas rau lawv.
Nkag Siab Graphite Electrode Jointitions
Graphite electrodes yog feem ntau muaj ntawm high-purity petroleum koob coke, uas yog ci thiab graphitized los txhim kho lawv cov kev coj ua thiab thermal kuj. Cov hluav taws xob no tsis yog ib qho xwb tab sis yog qhov hloov tau ua ntau ntu koom ua ke. Cov pob qij txha ntawm cov ntu no tseem ceeb heev, vim tias lawv yuav tsum tiv thaiv huab kub thiab kev ntxhov siab thaum tswj hwm hluav taws xob.
Cov haujlwm tseem ceeb ntawm electrode pob qij txha
Hluav Taws Xob Cov Hluav Taws Xob: Cov haujlwm tseem ceeb ntawm cov pob qij txha yog kom ntseeg tau tias tsis tshua muaj hluav taws xob ntws. Txhua qhov tsis kam ntawm kev sib koom ua ke tuaj yeem ua rau muaj cov cua kub nce ntxiv, muaj peev xwm ua kom lub electrodes thiab txo qis tag nrho kev ua tau zoo.
Neeg kho tshuab stability: EAF kev ua haujlwm muaj cov kev co loj thiab thermal expansion. Cov pob qij txha zoo pab tswj tus qauv kev ncaj ncees ntawm cov electrodes, tiv thaiv kev tiv thaiv lossis kev tsis sib haum xeeb thaum lub sijhawm ua haujlwm.
Kev tswj hwm thaum kub: muaj kev hloov cua sov muaj txiaj ntsig yog qhov tseem ceeb hauv EAF. Cov pob qij txha tsis zoo tuaj yeem tsim cov kub me me, ua rau tsis sib xws melting thiab nce rau ntawm cov electrodes. Cov pob qij txha kom zoo pab faib kom muaj mob hnyav dua ntawm cov chaw hluav taws xob.
Txo hauv qab: Kev saib xyuas nquag thiab hloov ntawm cov electrodes vim tias kev sib koom ua ke tuaj yeem ua rau muaj nqi tsawg. Kev ntseeg siab ua ke txuas lub neej ntawm cov electrodes thiab txo qhov xav tau kev hloov pauv, yog li txhawb kev tsim khoom.
Cov kev sib tw hauv electrode kev sib koom ua ke
Txawm hais tias lawv tseem ceeb, electrode pob qij txha ntaus ntau yam kev cov nyom. Qhov kub siab nyob rau hauv lub cub tawg tuaj yeem ua rau thermal nthuav dav thiab condaction, ua rau muaj peev xwm ua tsis tiav ntawm cov pob qij txha. Tsis tas li ntawd, impurities nyob rau hauv cov khoom sib koom tes tuaj yeem qhia kev tiv thaiv, cuam tshuam kev coj ua. Cov tuam txhab tsim nyog yuav tsum xyuam xim rau cov khoom siv zoo siv hauv cov pob qij txha thiab cov hau kev ua haujlwm los tsim lawv.
Kev nrhav thiab kev coj ua zoo tshaj plaws
Txhawm rau txhim kho kev ua yeeb yam ntawm graphite pob qij txha, ntau yam kev ua haujlwm tshiab thiab kev coj ua tau tshwm sim:
Advanced koom tes los: cov txuj ci zoo li lub tshuab nqus tsev thiab kev siv cov fillers high-purity cuas tau txhim kho kev sib luag ntawm cov pob qij txha, txo txoj kev pheej hmoo ntawm kev mob siab.
Kev saib xyuas thiab saib xyuas ib txwm muaj: kev siv sijhawm tu cov sijhawm txij nkawm uas suav nrog kev saib xyuas kev ncaj ncees tuaj yeem pab txheeb xyuas cov teeb meem ua ntej lawv ua rau cov teeb meem tsis txaus ntseeg.
Xaiv cov khoom siv: Siv cov khoom siv xaiv: Siv cov ntaub ntawv zoo, cov khoom siv tsis tshua muaj zog rau cov pob qij txha tuaj yeem txhim kho kev coj ua zoo thiab txo cov kev hnav ris tsho.
Tag
Qhov tseem ceeb ntawm graphite pob qij txha hauv hluav taws xob arc tsis tau dhau los. Lawv ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm tau zoo, tshuab ruaj khov, thiab txo qis qis. Raws li kev lag luam hlau txuas ntxiv mus hloov zuj zus, tsom mus rau qhov zoo thiab ua haujlwm ntawm cov pob qij txha no yuav yog qhov tseem ceeb ntawm EAF kev ua haujlwm. Los ntawm kev nqis peev hauv cov thev naus laus zis thiab cov kev coj ua zoo tshaj plaws, cov neeg loj heev tuaj yeem txhim kho kev ntseeg tau ntawm lawv EFS thiab pab txhawb kom yav tom ntej ntau dua.
