Nkag siab cov yam ntxwv thiab qhov zoo ntawm graphite electrodes: siab zog version
Graphite electrode yog ib yam khoom tseem ceeb siv rau smelting thiab melting hlau nyob rau hauv hluav taws xob arc rauv. Nws muaj cov conductivity siab thiab kub tsis kam, thiab muaj peev xwm tiv taus siab tam sim no ceev thiab kub ib puag ncig nyob rau hauv lub cub tawg. Nyob rau hauv hluav taws xob arc rauv, graphite electrode melts cov hlau raw cov ntaub ntawv los ntawm qhov kub siab generated los ntawm tam sim no kom paub txog cov smelting thiab smelting txheej txheem ntawm cov hlau. Hauv cov txheej txheem no, kev ua tau zoo thiab qhov zoo ntawm graphite electrode yuav cuam tshuam ncaj qha rau kev ruaj ntseg thiab kev ua haujlwm ntawm tag nrho cov txheej txheem smelting.
Lub siab- fais fab version ntawm graphite electrode yog ib qho electrode tshwj xeeb uas tsim los rau siab - fais fab arc rauv. Piv nrog rau cov hluav taws xob zoo tib yam, nws muaj cov khoom siv hluav taws xob ntau dua thiab kev hnav zoo dua, thiab haum rau siab - lub zog thiab siab - zaus ua haujlwm. Hauv qab no peb yuav qhia txog cov yam ntxwv thiab qhov zoo ntawm qhov siab - lub zog version ntawm graphite electrode kom ntxaws.
Ua ntej ntawm tag nrho cov, lub siab - lub hwj chim version ntawm graphite electrode muaj ntau dua conductivity. High- fais fab fais fab arc rauv feem ntau yuav tsum tau tiv taus qhov tam sim no loj, thiab cov conductivity ntawm electrode yog siab heev. Lub siab - lub hwj chim version ntawm graphite electrode siv high - purity graphite cov ntaub ntawv thiab cov txheej txheem tshwj xeeb, uas ua rau nws siv tau ntau dua, muaj peev xwm muab kev sib kis tau zoo dua tam sim no, txo lub zog poob, yog li txo lub zog noj thiab txhim kho kev tsim khoom.
Qhov thib ob, lub siab - lub zog version ntawm graphite muaj kev hnav zoo dua. Nyob rau hauv lub siab - fais fab hluav taws xob arc rauv, yam xws li kev sib cuag ntawm cov electrode thiab cov hlau molten thiab thermal expansion yuav ua rau kev sib txhuam thiab hnav ntawm electrode nto, txo cov kev pab cuam lub neej ntawm electrode. Lub siab- lub hwj chim version ntawm graphite electrode muaj cov qauv ruaj khov dua, thiab qhov saum npoo siv cov txheej tiv thaiv tshwj xeeb lossis ntxiv cov khoom hnav-cov ntaub ntawv tiv thaiv, uas tuaj yeem tiv taus hnav hauv qhov kub thiab txias ib puag ncig, ua kom lub neej ntev ntawm cov electrode, txo tus naj npawb ntawm kev hloov, thiab txo cov nqi kho.
Tsis tas li ntawd, lub siab - fais fab version ntawm graphite electrode muaj thermal stability zoo dua. Thaum lub sijhawm ua haujlwm ntawm lub siab - fais fab hluav taws xob arc rauv, cov electrode feem ntau raug thermal shock thiab thermal voj voog hloov. Yog tias cov khoom siv thiab cov qauv ntawm cov electrode nws tus kheej tsis tuaj yeem tiv thaiv kev ntxhov siab zoo, thermal tawg thiab deformation yog qhov tshwm sim, cuam tshuam rau kev siv cov electrode. Lub siab - lub hwj chim version ntawm graphite electrode siv cov khoom siv graphite zoo thiab cov cuab yeej ua haujlwm tshwj xeeb, muaj cov thermal conductivity zoo thiab thermal stability, tuaj yeem tiv taus qhov kub thiab txias hloov pauv, tswj cov duab thiab cov qauv ntawm cov electrode ruaj khov, thiab xyuas kom muaj kev ua haujlwm zoo ntawm lub cub tawg.
Nyob rau hauv cov ntsiab lus, lub siab - lub zog version ntawm graphite electrodes muaj ntau dua conductivity, zoo hnav tsis kam thiab zoo thermal stability. Nws yog qhov tsim nyog rau siab - lub zog thiab siab - zaus arc rauv ua haujlwm ib puag ncig, tuaj yeem txhim kho kev tsim khoom thiab kev ruaj ntseg ntawm arc furnaces, txo kev siv hluav taws xob thiab kev saib xyuas cov nqi, thiab yog ib qho tseem ceeb thiab cov khoom siv tseem ceeb hauv cov txheej txheem smelting thiab melting ntawm arc furnaces. Nrog kev txhim kho txuas ntxiv ntawm kev tsim khoom lag luam thiab kev loj hlob ntawm kev thov, siab - lub zog versions ntawm graphite electrodes yuav muaj kev siv dav dua thiab kev txhim kho ntxiv thiab kev txhim kho, ua kom muaj txiaj ntsig ntau dua rau kev txhim kho kev lag luam hlau smelting.
