Graphite electrodes ua lub luag haujlwm tseem ceeb hauv kev ua kom zoo hlau niaj hnub thiab cov txheej txheem smelting.Ua los ntawm cov khoom siv hluav taws xob zoo, cov khoom siv hluav taws xob zoo heev, cov khoom siv hluav taws xob no yog siv los ua qhov nruab nrab hauv hluav taws xob arc furnaces (EAFs) thiab ladle furnaces (LFs).Lawv cov yam ntxwv tshwj xeeb thiab cov khoom ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau kev kub-kub, cov ntawv thov tam sim no.
Ib qho tseem ceeb tshaj plaws ntawm graphite electrodes yog lawv cov thermal stability zoo heev.Lawv tuaj yeem tiv taus qhov kub siab heev yam tsis tau poob lawv cov qauv kev ncaj ncees lossis kev coj ua.Qhov no yog qhov tseem ceeb hauv cov txheej txheem hlau refining thiab smelting qhov twg qhov kub tuaj yeem ncav cuag ntau txhiab degrees Celsius.Graphite electrodes tuaj yeem ua haujlwm zoo rau cov xwm txheej no, ua kom muaj kev ua haujlwm zoo thiab txhim khu kev qha ntawm lub cub tawg.
Lwm tus yam ntxwv tseem ceeb ntawmgraphite electrodesyog lawv lub siab tsis kam oxidation thiab corrosion.Thaum lub sij hawm cov txheej txheem hlau refining, ntau yam tshuaj tiv thaiv tshwm sim, feem ntau muaj cov ntaub ntawv corrosive heev.Graphite electrodestiv thaiv oxidation thiab corrosion ua kom lawv lub neej ntev thiab kev ua haujlwm zoo ib yam hauv cov cheeb tsam hnyav.
Tsis tas li ntawd, graphite electrodes muaj cov coefficient tsawg ntawm thermal expansion.Qhov no txhais tau hais tias lawv pom qhov kev hloov pauv yam tsawg kawg nkaus thaum raug kub hloov pauv.Xws li kev ruaj ntseg yog qhov tseem ceeb hauv cov ntawv thov kev lag luam, vim tias txhua qhov kev nthuav dav lossis kev cog lus tuaj yeem ua rau muaj kev ntxhov siab thiab ua rau muaj kev puas tsuaj rau cov electrodes.Qhov qis coefficient ntawm thermal expansion ntawm graphite electrodes guarantees lawv cov qauv kev ncaj ncees thiab durability txawm nyob rau hauv huab ua hauj lwm tej yam kev mob.
Qhov tshwj xeeb conductivity ntawm graphite electrodes kuj tsim nyog tseem ceeb.Graphite yog cov khoom siv hluav taws xob zoo heev, tso cai rau kev hloov pauv hluav taws xob zoo hauv qhov cub.Qhov kev coj ua no yog qhov tseem ceeb hauv EAFs thiab LFs, qhov loj ntawm cov hluav taws xob tam sim no yuav tsum tau yaj cov hlau thiab ua tiav cov txheej txheem refining.Lub siab conductivity ntawm graphite electrodes kom tsawg zog poob thiab pom kev ua tau zoo ntawm cov furnaces.
Graphite electrodes muaj ntau yam txiaj ntsig thiab qhov zoo dua lwm cov ntaub ntawv uas feem ntau siv hauv cov txheej txheem hlau refining thiab smelting.Piv txwv li, piv rau tooj liab electrodes, graphite electrodes muaj tus nqi qis dua thiab tuaj yeem ua rau kub siab dua.Lawv kuj tseem tiv taus tshuaj lom neeg, ua rau lawv haum rau ntau yam kev siv.Tsis tas li ntawd, graphite electrodes muaj lub neej ntev dua thiab yuav tsum tau muaj kev saib xyuas tsawg dua, ua rau muaj txiaj ntsig tseem ceeb hauv lub sijhawm ntev.
Graphite electrodes muaj ib qho tshwj xeeb ntawm cov yam ntxwv uas ua rau lawv indispensable nyob rau hauv niaj hnub hlau refining thiab smelting txheej txheem.Lawv thermal stability, tsis kam oxidation thiab corrosion, tsawg coefficient ntawm thermal expansion, thiab zoo heev conductivity muab lawv sib nrug los ntawm lwm yam ntaub ntawv.Ua ke nrog lawv cov nqi-zoo thiab lub neej ntev, graphite electrodes yog qhov kev xaiv zoo tshaj plaws rau kev kub-kub, kev siv siab tam sim no hauv kev lag luam thoob ntiaj teb.Txawm hais tias nyob rau hauv hluav taws xob arc rauv los yog ladle furnaces, graphite electrodes ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj txiaj ntsig zoo, txhim khu kev qha, thiab ruaj khov hlau refining.
