Graphite electrodesua lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam, tshwj xeeb tshaj yog nyob rau hauv hluav taws xob arc furnaces.Cov electrodes no ua hluav taws xob thiab tsim kom muaj cua sov, tsim nyog rau cov hlau melting thiab refining hlau.Yog li ntawd, lawv yog qhov tseem ceeb rau kev tsim cov hlau, cov khoom siv hlau rov ua dua tshiab, thiab lwm yam txheej txheem hlau refining.Txawm li cas los xij, tus nqi ntawm graphite electrodes tuaj yeem sib txawv vim muaj ntau yam.
1. Raw Khoom Muaj thiab Nqi
Ib qho ntawm thawj yam cuam tshuam rau tus nqi graphite electrode yog qhov muaj thiab tus nqi ntawm nws cov khoom siv raw.Graphite electrodes feem ntau yog tsim los ntawm cov roj av koob zoo coke.Kev hloov pauv ntawm qhov muaj thiab tus nqi ntawm koob coke ncaj qha cuam tshuam rau tag nrho cov nqi ntawm graphite electrodes, ua rau muaj kev hloov pauv ntawm tus nqi hauv khw.
2.Shortage high-grade koob coke
Lwm qhov tseem ceeb tshaj plaws cuam tshuam rau tus nqi graphite electrode yog qhov tsis txaus ntawm qib siab koob coke.Needle coke, ib daim ntawv tshwj xeeb ntawm roj av coke, yog ib qho tseem ceeb raw cov ntaub ntawv uas yuav tsum tau rau zus tau tej cov graphite electrodes.Txawm li cas los xij, kev tsim cov koob tshuaj qib siab coke yog txwv thiab nyob ntawm kev lag luam roj av.Ib qho kev cuam tshuam hauv cov khoom siv los yog qhov tsis txaus nyob rau hauv qib siab koob coke muaj tuaj yeem ua rau muaj kev nce siab hauvgraphite electrode nqi.
3.High-zoo steel thov nce
Lwm yam tseem ceeb uas ua rau tus nqi hloov pauv ntawm graphite electrodes yog qhov xav tau ntau ntxiv rau cov hlau zoo.Raws li kev lag luam thoob ntiaj teb txuas ntxiv mus ntxiv, kev lag luam xws li tsheb, kev tsim kho, thiab kev tsim kho vaj tsev xav tau cov hlau nrog cov khoom zoo dua.Graphite electrodes yog ib qho tseem ceeb rau cov txheej txheem tsim khoom hauv EAF, qhov uas lawv muab cov cua sov tsim nyog thiab hluav taws xob conductivity rau smelting ntawm seem hlau, uas ua rau cov khoom zoo dua qub.
4.Electric arc furnaces tau tshwm sim raws li tus qauv ntawm lub sijhawm hauv kev lag luam steelmaking
Piv nrog rau cov tsoos blast furnaces, EAF muaj kev yooj yim dua, lub zog ua haujlwm, thiab txo qis carbon emissions.Covgraphite electorde khoomcia kev siv cov graphite electrodes hauv EAF pab txhawb cov smelting ntawm seem hlau, txo qhov xav tau ntawm raw cov ntaub ntawv thiab ua tus txheej txheem ntau environmentally friendly.Qhov kev hloov pauv ntawm EAF tau ua rau muaj kev xav tau ntawm graphite electrode, cuam tshuam rau lawv cov nqi.
5.Graphite electrodes yog cov khoom siv
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias graphite electrodes yog cov khoom siv tau, txhais tau tias lawv yuav raug hnav thiab tsim kua muag thaum lub sij hawm steelmaking.Kev sib cuag tsis tu ncua nrog cov cua sov thiab cov hluav taws xob tam sim no maj mam erodes cov graphite electrodes, yuav tsum tau hloov tsis tu ncua.Raws li qhov tshwm sim, kev noj cov graphite electrodes txuas ntxiv cuam tshuam rau lawv cov nqi hluav taws xob, nrog rau kev thov ntau ntxiv rau kev hloov pauv ua rau cov nqi hloov pauv.
6.Kev ua tsov ua rog ntawm lub ntiaj teb kev lag luam loj
Kev lag luam tsis tu ncua ntawm lub ntiaj teb kev lag luam loj kuj tau cuam tshuam tus nqi ntawm graphite electrodes.Raws li cov teb chaws tsim cov tariffs thiab kev txwv kev lag luam, lub ntiaj teb steel kev lag luam tab tom muaj kev hloov pauv hauv kev xa khoom thiab kev thov.Cov kev tsis sib haum xeeb ntawm kev lag luam no cuam tshuam qhov ruaj khov ntawm cov khoom siv raw, cuam tshuam rau qhov muaj thiab tus nqi ntawmgraphite electrodes.Tsis paub meej thiab tsis hloov pauv hauv kev lag luam thoob ntiaj teb qhia txog txheej txheej ntxiv ntawm qhov nyuaj thiab cuam tshuam rau tus nqi ntawm graphite electrodes.
Hauv kev xaus, tus nqi hloov pauv ntawm graphite electrodes yog cuam tshuam los ntawm ntau yam, suav nrog kev xav tau ntau ntxiv rau cov hlau zoo, kev nce qib ntawm cov hluav taws xob arc rauv, qhov khoom siv tau zoo ntawm graphite electrodes, tsis txaus ntawm qib siab koob coke, thiab kev ua lag luam tsis tu ncua.Txawm hais tias qhov kev hloov pauv zoo li no, graphite electrodes tseem yog ib qho tseem ceeb ntawm kev tsim steel, thiab kev siv zog tab tom ua los daws cov teeb meem no thiab ruaj khov lawv cov nqi.Kev lag luam steel txuas ntxiv tso siab rau cov kev daws teeb meem txhim khu kev qha los tsim cov hlau zoo zoo thiab ruaj khov.
