Graphite hluav taws xob yog tsuas yog siv nyob rau hauv cov txheej txheem statmaking. Hlau seem tau txais melted nyob rau hauv ib lub tshuab hluav taws xob arc thiab rov ua dua tshiab. Raws li ib hom neeg saib xyuas, lawv yog ib qho tseem ceeb hauv hom no
UHP Graphite electrodeyog tsuas yog ua los ntawm cov hmoov zoo koob coke, thiab dav siv nyob rau hauv ultra muaj zog hluav taws xob arc buraces.it muaj peev xwm nqa cov ceev tam sim no ntau dua 25a / CM2

Cov txheej txheem tsim khoom
Graphitation electrode feem ntau yog ua los ntawm roj coke thiab koob coke, sib xyaw nrog cov txheej txheem ntawm cov txheej txheem, sib sau, ci, graphing thiab machining, thaum kawg yuav tsum tau khoom. Nov yog qee qhov kev piav qhia rau qee cov txheej txheem tsim khoom:
Kneading: Nplawm thiab sib tov ib qho kev siv cov pa roj carbon hais thiab hmoov nrog qee yam ntawm phau ntawv ntsuas kub, tus txheej txheem no hu ua kneading.
Txoj haujlwm ntawm kneading:
①MIX Txhua yam khoom siv raw uayees, thiab nyob rau tib lub sijhawm ua cov ntaub ntawv carbon mones
②②ter Ntxiv thee asphalt, tau txais tag nrho cov khoom khov kho ua ke.
③③ome plias pitches nkag mus rau sab hauv voids, uas ntxiv txhim kho lub ntom ntom thiab adhesion ntawm cov tshuaj txhuam.
Txoj kev sib sau:Lub kneaded carbon muab tshuaj txhuam yog extruded mus rau hauv lub cev ntsuab (lossis cov khoom ntsuab) nrog qee yam duab, qhov loj me, ntom ntom thiab lub zog hauv cov khoom siv pwm. Tus muab tshuaj txhuam muaj cov yas cais tawm hauv qab lub zog sab nraud.
Ci ntsa iabKuj tseem hu ua ci, nws yog qhov kev kub ntxhov ntawm cov pa hluav taws xob rau Coke ua ke nrog kev sib xyaw ua ke nrog kev sib xyaw ua ke nrog cov khoom siv hluav taws xob siab, zoo dua qub kev ruaj khov thiab tshuaj ruaj khov.
Thib ob uas ci ntsa iab yog yuav ci ib zaug ntxiv, ua rau lub ntsej muag pitch carbonized. Cov hluav taws xob (txhua hom tshwj tsis yog qhov yuav tsum tau ua kom ntev dua yog qhov yuav tsum tau ua zaum ob, thiab mis tsib-dip plaub-ci lossis ob-dip peb-ci.
