Kev noj cov graphite electrodes feem ntau cuam tshuam rau qhov zoo ntawm cov electrodes lawv tus kheej, tab sis kuj rau kev ua haujlwm steel thiab txheej txheem (xws li qhov ceev tam sim no los ntawm electrodes, smelting steel, qhov zoo ntawm cov hlau seem thiab cov pa oxygen ntev ntawm lub block. kev sib txhuam, thiab lwm yam).
(1) Sab saum toj ntawm cov electrode yog noj. Kev noj haus suav nrog sublimation ntawm cov khoom siv graphite uas tshwm sim los ntawm qhov kub thiab txias thiab tsis muaj tshuaj lom neeg cov tshuaj tiv thaiv ntawm cov hluav taws xob huab cua thiab molten steel thiab slag, thiab kev noj ntawm cov hluav taws xob huab cua tseem cuam tshuam txog seb cov electrode yog ntxig rau hauv cov hlau molten. carburize.
(2) Oxidation poob rau sab nrauv ntawm electrode. Nyob rau hauv xyoo tas los no, txhawm rau txhim kho tus nqi smelting ntawm hluav taws xob rau hluav taws xob, kev ua haujlwm oxygen tshuab feem ntau yog siv, uas ua rau kev nce ntawm electrode oxidation poob. Raws li ib txwm muaj, oxidation poob ntawm sab nrauv ntawm cov electrode suav txog li 50% ntawm tag nrho cov khoom siv ntawm electrode.
(3) Residual poob ntawm electrodes los yog pob qij txha. Ib feem me me ntawm electrode los yog sib koom ua ke (piv txwv li, residue) uas yog siv txuas ntxiv mus txuas rau sab sauv thiab sab hauv electrodes yog nquag poob thiab nce noj.
(4) Poob electrode breakage, nto tev thiab ntog blocks. Peb hom electrode poob no yog sau ua ke hu ua mechanical losses, qhov uas ua rau electrode breakage thiab ntog tawm yog qhov teeb meem ntawm qhov kev huam yuaj uas tau txheeb xyuas los ntawm steel zeb thiab graphite electrode ntau lawm cog, vim hais tias tej zaum yuav yog vim lub zoo thiab ua cov teeb meem ntawm graphite electrode (tshwj xeeb tshaj yog cov electrode sib koom), los yog tej zaum yuav muaj teeb meem nyob rau hauv lub steelmaking lag luam.
Kev siv hluav taws xob tsis pom zoo xws li oxidation thiab sublimation ntawm qhov kub thiab txias feem ntau hu ua "net noj", thiab "net noj" ntxiv rau cov khoom siv poob xws li kev tawg thiab qhov seem poob yog hu ua "tag nrho noj". Tam sim no, ib qho kev noj ntawm graphite electrode ib tuj ntawm hluav taws xob rauv hlau hauv Suav teb yog 1.5 ~ 6kg. Nyob rau hauv tus txheej txheem ntawm steel smelting, lub electrode yog maj oxidized thiab noj rau hauv lub khob hliav qab. Feem ntau saib lub taper ntawm lub electrode thiab redness ntawm lub electrode lub cev nyob rau hauv tus txheej txheem ntawm steel ua yog ib tug intuitive txoj kev los ntsuas oxidation tsis kam ntawm graphite electrode.
