Graphite electrodeyog ib hom electrode siv nyob rau hauv high-temperature hluav taws xob daim ntaub ntawv, tshwj xeeb tshaj yog nyob rau hauv zus tau tej cov hlau los ntawm cov hluav taws xob arc rauv (EAF) txheej txheem.Graphite electrodes yog cov khoom tseem ceeb nyob rau hauv txoj kev no ntawm steelmaking, qhov uas lawv ua hluav taws xob tam sim no los yaj seem steel thiab lwm yam ntaub ntawv raw.
Graphite electrodes feem ntau yog tsim los ntawm kev sib xyaw ntawm roj av coke, suab, thiab lwm yam khoom siv carbonaceous.Cov ntaub ntawv no yog compressed thiab ci los ua cov electrode.Qhov tshwm sim ntawm graphite electrode muaj hluav taws xob conductivity siab, kub tsis kam, thiab zoo txhua yam muaj zog, ua rau nws zoo tagnrho rau siv nyob rau hauv cov huab cua ntawm ib tug hluav taws xob arc rauv.
Cov txheej txheem hluav taws xob arc rauv yog txoj kev nrov rau kev tsim cov hlau vim nws qhov yooj yim thiab muaj peev xwm siv ntau yam khoom siv raw.Nyob rau hauv cov txheej txheem no, seem hlau thiab lwm yam ntaub ntawv raw yog melted siv lub tshav kub generated los ntawm ib tug hluav taws xob arc ntawm lubgraphite electrodesthiab cov hlau tau melted.Cov hluav taws xob tam sim no dhau los ntawm graphite electrodes, tsim kom muaj cua sov uas ua rau cov ntaub ntawv melts, tso cai rau cov impurities raug tshem tawm thiab cov ntsiab lus alloying ntxiv los tsim cov qib steel xav tau.
Graphite electrodes tuaj nyob rau hauv ntau qhov ntau thiab tsawg thiab qib kom tau raws li cov kev cai tshwj xeeb ntawm kev siv steelmaking sib txawv.Txoj kab uas hla thiab qhov ntev ntawm cov electrodes tuaj yeem sib txawv nyob ntawm qhov muaj peev xwm thiab kev tsim hluav taws xob arc rauv.Tsis tas li ntawd, qhov zoo thiab muaj pes tsawg leeg ntawm graphite electrode, nrog rau nws qhov ceev thiab thermal conductivity, ua lub luag haujlwm tseem ceeb hauv kev ua tau zoo thiab kev ua haujlwm ntawm cov txheej txheem steelmaking.
Ib qho ntawm cov tseem ceeb hauv kev ua haujlwm ntawm graphite electrodes yog lawv cov tsis kam oxidation thiab thermal shock.Thaum lub sij hawm steelmaking txheej txheem, graphite electrodes raug rau huab cua kub thiab tshuaj tiv thaiv.Lub peev xwm ntawm cov electrodes los tiv thaiv cov mob hnyav no yam tsis muaj kev puas tsuaj yog qhov tseem ceeb rau kev ua haujlwm ruaj khov thiab txhim khu kev qha ntawm hluav taws xob arc rauv.
Graphite electrodes tseem ua lub luag haujlwm tseem ceeb hauv tag nrho cov nqi thiab lub zog ua haujlwm ntawm cov hlau ntau lawm.Los ntawm kev muab hluav taws xob ua tau zoo thiab hloov hluav taws xob, cov khoom siv hluav taws xob zoo graphite ua rau txo qis kev siv hluav taws xob thiab txhim kho cov kev ua tau zoo ntawm cov hluav taws xob arc rauv.Qhov no, nyob rau hauv lem, tuaj yeem ua rau kev txuag nqi thiab cov txiaj ntsig ib puag ncig hauv kev ua haujlwm steel.
Ntxiv rau lawv cov kev siv tseem ceeb hauv kev lag luam steel, graphite electrodes muaj kev siv hauv lwm cov txheej txheem kub, xws li kev tsim cov ferroalloys, silicon hlau, thiab lwm yam tshwj xeeb alloys.Cov txheej txheem no kuj tso siab rau cov khoom siv hluav taws xob thiab thermal ntawm graphite electrodes kom ua tiav cov txiaj ntsig xav tau.
Zuag qhia tag nrho, graphite electrodes yog cov khoom tseem ceeb hauv kev siv hluav taws xob kub kub, tshwj xeeb tshaj yog nyob rau hauv steelmaking los ntawm cov txheej txheem hluav taws xob arc rauv.Lawv tshwj xeeb ua ke ntawm hluav taws xob conductivity, thermal kuj, thiab txhua yam muaj zog ua rau lawv indispensable rau melting thiab refining hlau thiab lwm yam ntaub ntawv.Raws li steel ntau lawm evolve, qhov kev thov rau high-zoo graphite electrodes yuav tsum nyob twj ywm muaj zog, tsav tsheb mus rau hauv lawv muaj pes tsawg leeg, kev ua tau zoo, thiab sustainability nyob rau hauv lub steelmaking kev lag luam.
