Cov thev naus laus zis ntawm cov txheej txheem antioxidant rau graphite electrode, yog siv ntawm graphite electrodes ntawm hluav taws xob-arc rauv taws ua kom sov. nws yog los ntawm novolac epoxy, polyvinyl formal acetal, phosphoric acid, silicon carbide, silicon-dioxide, cov khoom sib xyaw ua ke xws li aluminium oxide, ferric oxide, boron nitride, norbide.be ib hom slurries, tuaj yeem nrog txhuam, tshuaj tsuag, pleev xim lossis impregnating txoj kev thawj txheej txheej ntawm qhov chaw electrode hauv qab electrode dop, muaj tias cov nplaum hluav taws xob yog qhov loj, oxidation-tsis kam yog qhov muaj zog, siv cov txiaj ntsig yooj yim, siv cov graphite electrode noj kom txo los ntawm 0.8-1.0kg rau ib tuj ntawm steel 7-8kg ntawm thawj txhua txhua refining puav.0933a tom qab graphite electrode antioxidant txheej txheem tshiab thev naus laus zis txheej tshiab - ncua graphite electrode siv sijhawm 26 ~ 70.4%.
Hauv cov txheej txheem ntawm kev siv graphite electrode rau hluav taws xob arc rau hluav taws xob thaum tsim cov hlau, vim qhov kub ntawm qhov chaw tiv thaiv kev kub ntxhov, qhov cuam tshuam ntawm lub sab electrode yog li 60% ntawm tag nrho kev noj. graphite electrode cov tshuaj tua kab mob hauv 600 ~ 1800 ℃ ntau, tuaj yeem zam kev tiv thaiv electrode nrog huab cua ncaj qha los txo cov nplaim oxidation ntawm graphite electrode thiab ua rau lub neej muaj hluav taws xob ntev.
Cov khoom siv impregnated tuaj yeem siv ua ke nrog cov txheej txheej, thiab cov tshuaj tiv thaiv los tiv thaiv kab mob tuaj yeem txhim kho tau zoo heev. cov oxidation tiv topcoating nyob rau hauv cov roj carbon cov khoom kub, yuav siv tau rau ntawm cov graphite electrodes uas hluav taws xob-arc rauv taws ua kom siv, ua si qhov kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv graphite electrode los tiv thaiv oxidation kev sib piv raws li hauv qab hom ntawv:

NCO TSEG: Cov ntaub ntawv yog cov txiaj ntsig ntawm kev tiv thaiv kev tiv thaiv oxidation ntawm graphite electrode ntawm 4 lub Cuaj Hlis 2017 los ntawm suzhou iron & steel pawg.
Kev txo qis ntawm lub zog siv hluav taws xob yog suav raws li kev sim sim ntawm cov mills steel.
