Graphite electrodesyog cov khoom tseem ceeb hauv kev ua haujlwm ntawm arc furnaces, ua haujlwm tseem ceeb hauv ntau yam kev lag luam.
Graphite electrodes feem ntau yog tsim los ntawm cov pa roj carbon hu ua graphite, uas yog crystalline daim ntawv ntawm cov khoom carbon.Graphite muaj cov khoom tshwj xeeb uas ua rau nws zoo tagnrho rau kev siv hauv electrodes, xws li nws cov hluav taws xob ua hluav taws xob, siab ua haujlwm kub thiab tshuaj lom neeg, thiab qis coefficient ntawm thermal expansion.Cov khoom no pab kom graphite electrodes ua tau zoo tshwj xeeb hauv kev siv arc rauv.
Covgraphite electrodes manufacturing txheej txheemkoom nrog ob peb kauj ruam.Nws pib nrog kev xaiv cov khoom zoo graphite, uas yog tom qab ntawd hauv av thiab sib xyaw nrog cov khoom siv khi, xws li thee tar pitch lossis roj av coke.Qhov kev sib xyaw no yog tom qab ntawd ua rau hauv daim ntawv xav tau electrode siv cov txheej txheem molding.Tom qab molding, cov electrodes raug rau lub ci txheej txheem kom tshem tawm cov binder thiab ntxiv dag zog rau cov qauv carbon.Qhov no yog ua raws li cov txheej txheem graphitization, uas suav nrog cov cua sov ntawm cov electrodes mus rau qhov kub ntawm ib ncig ntawm 3000 degrees Celsius los hloov lawv mus rau hauv graphite.Thaum kawg, cov electrodes tau dhau los ua cov kev ntsuam xyuas zoo los xyuas kom meej lawv cov kev ua tau zoo thiab kev ntseeg tau.
Graphite electrodes nrhiav kev siv dav hauv ntau yam kev lag luam, tshwj xeeb hauv cov hluav taws xob arc rauv taws.Cov furnaces no yog siv los tsim cov hlau, qhov twg graphite electrodes ua cov khoom siv hluav taws xob los tsim thiab tswj cov hluav taws xob arc, uas melts cov ntaub ntawv raw thiab tso cai rau tsim cov hlau molten.Tsis tas li ntawd, graphite electrodes yog siv nyob rau hauv lwm yam metallurgical txheej txheem xws li zus tau tej cov ferroalloys, silicon hlau, thiab calcium carbide.
Qhov tseem ceeb ntawm graphite electrodes nyob rau hauv industrial chaw tsis tuaj yeem overstated.Lawv cov thermal conductivity siab tso cai rau kev hloov hluav taws xob zoo, ua kom nrawm dua thiab meej dua ntawm cov ntaub ntawv hauv arc furnaces.Graphite electrodes kuj muaj kev tiv thaiv zoo heev rau thermal shock, tiv thaiv lawv los ntawm kev tawg lossis tawg nyob rau hauv huab cua kub.Qhov kev ua haujlwm ntev no ua kom lub neej ntev ntawm electrode thiab txo qis qis qis thiab kho cov nqi.
Tsis tas li ntawd, lubgraphite electrodes hluav taws xob conductivityyog lwm qhov tseem ceeb hauv lawv cov kev lag luam tseem ceeb.Lub siab conductivity ua kom muaj txiaj ntsig zoo ntawm cov hluav taws xob los ntawm cov electrodes, uas ua rau muaj kev ruaj khov thiab zoo ib yam thaum lub sij hawm melting txheej txheem.Qhov no ua kom lub cev tsis sib xws thiab tswj kev faib tawm ntawm cov cua sov, ua rau kev txhim kho steel zoo thiab sib xws.
Qhov loj thiab qhov zoo ntawm graphite electrodes cuam tshuam rau lawv qhov kev ua tau zoo hauv kev ua haujlwm arc rauv.Qhov ntev ntawm cov electrodes, xws li lawv txoj kab uas hla thiab ntev, sib txawv nyob ntawm seb lub qhov cub tsim tshwj xeeb thiab cov khoom yuav tsum tau ua.Cov neeg tsim khoom tsim ntau qhov ntau thiab tsawg ntawm cov khoom siv hluav taws xob kom haum rau ntau hom cub tawg thiab muaj peev xwm.
Manufacturers ntawm graphite electrodesua lub luag haujlwm tseem ceeb hauv kev muab cov khoom tseem ceeb no rau kev lag luam thoob ntiaj teb.Cov tuam txhab lag luam no yuav tsum ua raws li kev tswj hwm nruj kom ntseeg tau tias cov khoom siv hluav taws xob ua tau raws li cov qauv kev lag luam.Kev tswj kom zoo nyob rau hauv cov khoom siv lub cev, xws li qhov ceev thiab thermal nthuav dav, xws li cov hluav taws xob, xws li hluav taws xob tsis kam.Los ntawm kev tswj xyuas cov qauv zoo ib yam, cov tuam txhab graphite electrode pab txhawb rau tag nrho cov txiaj ntsig thiab kev tsim khoom ntawm kev ua haujlwm ntawm arc.
Hauv kev xaus, graphite electrodes yog qhov tseem ceeb hauv kev ua haujlwm ntawm arc furnaces thiab ua lub luag haujlwm tseem ceeb hauv ntau cov txheej txheem kev lag luam.Lawv cov khoom tshwj xeeb, xws li hluav taws xob siab, thermal tsis kam, thiab kav ntev, ua rau lawv zoo tagnrho rau siv hauv cov ntawv thov no.Kev tsim cov txheej txheem ntawm graphite electrodes yuav tsum tau ceev faj xaiv cov khoom zoo graphite, ua raws li cov kauj ruam xws li kev sib tov, shaping, ci, thiab graphitization.Graphite electrodes nrhiav kev siv hauv steel ntau lawm thiab ntau yam txheej txheem metallurgical.Lawv qhov tseem ceeb yog nyob rau hauv lawv lub peev xwm los hloov cov cua sov, tiv thaiv thermal shock, thiab muab hluav taws xob ruaj khov.Zuag qhia tag nrho, graphite electrode manufacturers ua lub luag haujlwm tseem ceeb hauv kev muab cov khoom siv hluav taws xob zoo thiab ua kom muaj txiaj ntsig thiab kev ntseeg siab ntawm kev lag luam.
