Kev tau noj ntawm graphite electrodes?

Kev tau noj ntawm graphite hluav taws xob hauv hluav taws xob rauv stat steelmaking, txawm hais tias muaj kev ua haujlwm txuas ntxiv, txawm hais tias muaj kev ua haujlwm txuas ntxiv, thiab lub sijhawm sib txuas, hluav taws xob daws teeb meem, thiab lwm yam).
1. Xaus
Xws li cov khoom noj kom nce los ntawm qhov kub ntawm lub arc thiab poob ntawm cov tshuaj lom neeg ntawm electrode thiab lub molten hlau thiab slag. Tus nqi kub nce ntxiv ntawm qhov kawg feem ntau yog nyob ntawm qhov ceev tam sim no dhau los ntawm cov electrode, thiab cov thib ob ntawm electrode sab tom qab oxidation. Kev noj khoom xaus tseem cuam tshuam txog seb cov electrode nyob rau hauv cov hlau nplaum kom ua kom cov roj carbon.
2. Sab oxidation
Tshuaj lom neeg muaj pes tsawg leeg ntawm electrode yog carbon. Cov pa roj carbon yuav yauv tawm cov pa oxidation nrog huab cua, dej vapor, thiab carbon dioxide nyob rau qee yam. Qhov ntau ntawm oxidation ntawm electrode sab yog cuam tshuam nrog chav ntsuas oxidation thiab thaj chaw. Nyob rau hauv ib txwm muaj xwm txheej, tus nqi ntawm oxidation ntawm electrode sab account rau li 50% ntawm tag nrho cov electrode noj. Nyob rau hauv xyoo tsis ntev los no, nyob rau hauv thiaj li yuav nce qhov ceev ntawm hluav taws xob rauv smas, qhov zaus ntawm cov pa oxygen ua haujlwm tau nce, ua rau muaj kev nce oxidation poob ntawm electrode. Nquag saib cov liab ntawm lub pob zeb electrode thiab tus taper ntawm qis kawg thaum kawg thaum lub sij hawm steelmaking yog ib txoj kev sib txuam yog qhov muaj peev xwm los ntsuas hluav taws xob lub peev xwm.
3. Poob ntawm cov seem kawg
Thaum lub electrode yog siv txuas ntxiv mus rau kev sib koom tes ntawm cov electrodes sab saud thiab sib koom tes nrog oxidation) yog ib qho chaw so thiab ua haujlwm ntawm oxidation thiab thinning ntawm lub cev lossis nkag mus ntawm qhov tawg. Qhov loj me ntawm cov seem kawg poob yog cuam tshuam nrog cov qauv ntawm cov qauv ntawm cov electrode, thiab kev sib cav thiab cuam tshuam ntawm cov hluav taws xob.
4. Nto Deg thiab Thaiv Poob
Qhov tshwm sim ntawm kev txias txias thiab cua sov thaum lub sijhawm smelting, thiab cov thermal thermal kev co tiv thaiv ntawm cov electrode nws tus kheej.
5. Electrode breakage
Suav nrog electrode pob tw breakage thiab sib koom ua ke. Kev rhuav tshem hluav taws xob muaj feem xyuam rau kev koom tes zoo thiab kev sib koom tes ntawm graphite electrode thiab cov sib koom tes nws tus kheej, nrog rau kev ua haujlwm steelmaking. Qhov ua rau muaj tshwm sim yog feem ntau ua kom pom tseeb ntawm cov hlau mills thiab electrode manufacturers.
Cov khoom siv tseem ceeb rau kev tsim cov graphite hluav taws xob yog roj coke. Lub zog hluav taws xob zoo li hluav taws xob tuaj yeem ntxiv cov coke asphalt me ​​me. Cov Sulfur cov ntsiab lus ntawm roj av coke thiab asphalt coke tsis tau tshaj 0.5%. Koob coke kuj yuav tsum tau thaum tsim lub zog loj lossis ultra - lub zog loj graphite hluav taws xob.
