Dab tsi yog graphite electrode?
Graphite electrode feem ntau yog siv rau hluav taws xob arc rauv thiab submerged cua sov thiab cov cua sov ua haujlwm ua tus neeg xyuas pib zoo. Nyob rau hauv tus nqi ntawm hluav taws xob arc rauv steelmaking, kev noj ntawm graphite electrodes account rau txog 10%.
Nws yog ua los ntawm cov roj av coke thiab pitch coke, thiab qib siab-power thiab ultra-high-power yog ua los ntawm koob coke. Lawv muaj cov ntsiab lus tsis tshua muaj tshauv, zoo hluav taws xob conductivity, tshav kub, thiab corrosion kuj, thiab yuav tsis yaj los yog deform nyob rau hauv high kub.
Hais txog graphite electrode qib thiab diameters.
JINSUN muaj ntau qib thiab txoj kab uas hla. Koj tuaj yeem xaiv los ntawm RP, HP lossis UHP qib, uas tuaj yeem pab koj txhim kho hluav taws xob arc rauv kev ua tau zoo, ua kom cov khoom ua tau zoo, thiab ua kom muaj txiaj ntsig kev lag luam. Peb muaj ntau txoj kab uas hla, 150mm-700mm, uas tuaj yeem siv rau kev ua haujlwm smelting ntawm hluav taws xob arc rauv ntawm cov tonnages sib txawv.
Kev xaiv kom raug ntawm electrode hom thiab qhov loj me yog qhov tseem ceeb heev. Qhov no yuav ua lub luag haujlwm tseem ceeb hauv kev ua kom ntseeg tau qhov zoo ntawm cov hlau smelted thiab kev ua haujlwm ib txwm muaj ntawm hluav taws xob arc rauv.
Nws ua haujlwm li cas hauv eaf steelmaking?
Graphite electrode qhia hluav taws xob tam sim no rau hauv lub tshuab ua hlau, uas yog cov txheej txheem hluav taws xob arc rauv steelmaking. Cov tam sim no muaj zog yog kis los ntawm lub cub tawg transformer los ntawm lub cable mus rau lub tuav ntawm qhov kawg ntawm peb electrode caj npab thiab ntws mus rau hauv nws.
Yog li ntawd, ntawm qhov kawg ntawm electrode thiab tus nqi ib qho arc tawm tshwm sim, thiab tus nqi pib yaj siv cov cua sov los ntawm arc thiab tus nqi pib yaj. Raws li lub peev xwm ntawm lub tshuab hluav taws xob, cov chaw tsim khoom yuav xaiv cov kab sib txawv rau kev siv.
Txhawm rau txuas ntxiv siv cov electrodes thaum lub sij hawm smelting txheej txheem, peb txuas cov electrodes los ntawm threaded txiv mis. Txij li qhov hla ntu ntawm lub txiv mis yog me dua li ntawm cov electrode, lub txiv mis yuav tsum muaj zog compressive ntau dua thiab qis dua li cov electrode.
Tsis tas li ntawd, muaj ntau qhov ntau thiab tsawg, nyob ntawm seb lawv siv thiab cov kev cai tshwj xeeb ntawm eaf steelmaking txheej txheem.
