Tam sim no, cov kev ntsuas tseem ceeb los txo cov electrode noj yog:
Optimize fais fab mov system parameters. Cov khoom siv hluav taws xob tsis zoo yog qhov tseem ceeb cuam tshuam rau kev siv electrode. Piv txwv li, rau lub cub tawg 60t, thaum qhov hluav taws xob theem nrab yog 410V thiab qhov tam sim no yog 23kA, qhov kev siv hluav taws xob pem hauv ntej tuaj yeem txo qis.
Water-cooled composite electrode yog saws. Water-cooled composite electrode yog ib hom tshiab electrode tsim tawm txawv teb chaws nyob rau xyoo tas los no. Cov dej-txias sib xyaw electrode yog tsim los ntawm cov dej-txias steel raj sab sauv thiab sab qis graphite ua haujlwm, thiab cov dej-txias seem suav txog li 1/3 ntawm qhov ntev ntawm cov electrode. Txij li thaum tsis muaj qhov kub siab oxidation (graphite oxidation) nyob rau hauv cov dej-txias steel raj ntu, cov electrode oxidation raug txo, thiab cov dej-txias steel raj seem tswj kev sib cuag zoo nrog cov gripper. Txij li cov xov ntawm cov dej-txias ntu thiab graphite seem txais cov dej-txias hom, nws cov duab yog ruaj khov, tsis muaj kev puas tsuaj, thiab tuaj yeem tiv taus lub zog loj, uas txhim kho lub zog ntawm electrode interface, yog li txo cov electrode noj.
Anti-oxidation mechanism ntawm dej tsuag graphite electrode yog saws. Nyob rau hauv kev pom ntawm kev noj cov electrodes nyob rau hauv cov txheej txheem smelting, cov kev ntsuas ntawm graphite electrode dej txau thiab oxidation tiv thaiv yog saws, uas yog hais tias, lub nplhaib dej txau cov cuab yeej yog saws hauv qab cov electrode griper los tsuag dej ntawm electrode nto, yog li ntawd. uas dej ntws los ntawm electrode nto, thiab lub nplhaib yeeb nkab yog siv los tshuab compressed cua rau saum npoo tam sim no saum lub qhov hluav taws xob ntawm lub qhov cub npog, thiaj li ua kom cov dej ntws tawm. Siv txoj kev no, kev noj ntawm tuj steel electrode txo qis dua. Cov thev naus laus zis tshiab yog thawj zaug siv rau hauv lub tshuab hluav taws xob ultra-high fais fab. Cov txheej txheem dej txau electrode yog yooj yim, yooj yim rau kev khiav lag luam thiab nyab xeeb.
Electrode nto txheej tshuab. Electrode txheej tshuab yog ib txoj hauv kev yooj yim thiab siv tau los txo cov electrode noj.
Cov khoom siv feem ntau siv electrode txheej yog aluminium thiab ntau yam khoom siv ceramic, uas muaj zog oxidation tsis kam ntawm qhov kub thiab muaj peev xwm txo tau cov oxidation noj ntawm electrode sab saum npoo.
Dip electrode yog siv. Lub dip electrode yog dip cov electrode rau hauv cov tshuaj lom neeg tus neeg sawv cev thiab ua rau saum npoo ntawm electrode cuam tshuam nrog tus neeg sawv cev los txhim kho qhov tsis kam ntawm cov electrode kom kub oxidation. Cov electrode noj yog txo los ntawm 10% ~ 15% piv nrog cov electrode ib txwm.
