Graphite electrodes thawj zaug tshwm sim nyob rau hauv thaum ntxov 20th caug xyoo thiab tau siv rau abrasive ua. Nws tsis yog txog thaum xyoo 1930 uas lawv tau pib siv hluav taws xob arc rauv smelting. Thaum xyoo 1960s, cov teb chaws txawv teb chaws tau pib siv cov khoom siv hluav taws xob muaj zog, siab ceev graphite electrodes, uas txhim kho qhov zoo ntawm cov hluav taws xob arc rauv. Txawm li cas los xij, vim muaj kev ywj pheej ntawm txawv teb chaws graphite electrode thev naus laus zis, Tuam Tshoj tau ntev cia siab rau cov graphite electrodes txawv teb chaws, uas tau txwv txoj kev loj hlob ntawm domestic hluav taws xob arc rauv smelting. Txhawm rau daws qhov teeb meem no, cov kws tshawb fawb hauv tsev tau pib koom nrog kev tshawb fawb thiab kev tsim cov graphite electrodes.
Thaum ntxov xyoo 1980, kuv lub teb chaws graphite electrode ntau lawm tshuab tau pib coj zoo. Txawm li cas los xij, vim muaj kev txwv ntawm cov khoom siv raw thiab cov txheej txheem, kev ua haujlwm thiab kev ua neej ntawm graphite electrodes tseem tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev lag luam metallurgical hauv tsev. Yog li ntawd, kuv lub teb chaws tau pib ua cov kev tshawb fawb thiab kev loj hlob ntawm graphite electrode loj, thiab ntau hom graphite electrodes tau tshwm sim ib qho tom qab, xws li high-power graphite electrodes, ultra-high-power graphite electrodes, thiab lwm yam.
Graphite electrode yog cov khoom siv hluav taws xob tseem ceeb, feem ntau siv rau hauv cov txheej txheem ntawm electrolytic aluminium, tooj liab thiab lwm yam hlau. Nws yog ua los ntawm high-purity graphite khoom thiab muaj hluav taws xob zoo conductivity, thermal stability thiab tshuaj stability. Nws yog ib qho tseem ceeb ntawm cov khoom siv hauv cov txheej txheem electrolysis.
Graphite electrodes feem ntau muab faib ua ob hom: carbon electrodes thiab graphite electrodes. Cov graphite electrode yog cov cua kub kub-kho cov pa roj carbon electrode. Cov txheej txheem tsim khoom ntawm graphite electrodes suav nrog ntau cov kauj ruam xws li kev sib xyaw, molding, ziab, thiab kev kho cua sov. Txhua kauj ruam hauv kev tsim khoom muaj qhov cuam tshuam tseem ceeb rau qhov zoo thiab kev ua haujlwm ntawm cov khoom kawg.
Graphite electrodes muaj ntau yam zoo, xws li siab zog, siab conductivity, kub stability thiab tshuaj stability. Cov khoom no ua rau nws siv dav hauv kev lag luam xws li casting, refractory cov ntaub ntawv, graphite chemistry, electrolytic aluminium thiab steel smelting. Nyob rau tib lub sijhawm, graphite electrode kuj yog ib qho tseem ceeb ntawm cov khoom siv hauv ib puag ncig. Vim nws siab purity thiab recyclability, nws daim ntawv thov nyob rau hauv petrochemical, nonferrous hlau thiab lwm yam industries tau nyiam ntau thiab ntau xim.
Nyob rau hauv luv luv, graphite electrode yog ib qho tseem ceeb cov ntaub ntawv nrog dav daim ntawv thov prospects thiab kev lag luam xav tau. Nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho txuas ntxiv ntawm cov txheej txheem ntau lawm, kev ua haujlwm thiab kev ua tau zoo ntawm graphite electrodes kuj tseem yuav txhim kho ntxiv.
Tib lub sijhawm, graphite electrode yog cov khoom tseem ceeb uas siv dav hauv metallurgy, tshuaj lom neeg kev lag luam, hluav taws xob fais fab thiab lwm yam haujlwm. Nws lub ntsiab siv yog raws li cov khoom siv electrode rau hluav taws xob arc rauv. Graphite electrodes yog tsim los ntawm ib qib tshwj xeeb ntawm cov khoom siv graphite uas muaj cov yam ntxwv ntawm purity siab, siab ceev, siab zog thiab siab conductivity. Hauv cov txheej txheem hluav taws xob arc rauv smelting, graphite electrodes ua lub luag haujlwm tseem ceeb, thiab lawv cov kev ua tau zoo cuam tshuam ncaj qha rau kev tsim khoom thiab cov khoom zoo.
