Hauv nruab nrab zaus inverter chaw vuam, kev xaiv ntawm electrodes plays lub luag haujlwm tseem ceeb hauv kev ua tiav qhov xav tau vuam. Ntau hom electrodes tuaj yeem muaj qhov sib txawv ntawm qhov vuam zoo, kev ua haujlwm zoo, thiab kev ua haujlwm tag nrho. Qhov tsab xov xwm no aims los tshawb xyuas cov txiaj ntsig vuam tau nrog cov electrodes sib txawv hauv nruab nrab zaus inverter qhov chaw vuam.
Tooj Electrodes:
tooj liab electrodes yog dav siv nyob rau hauv qhov chaw vuam vim lawv zoo heev thermal conductivity thiab high hluav taws xob conductivity. Lawv muab hluav taws xob hloov pauv tau zoo, ua rau muaj cua sov sai thiab sib xws ntawm cov khoom ua haujlwm. Copper electrodes kuj pom zoo tiv thaiv hnav thiab deformation, kom ntseeg tau tias vuam zoo ib yam dhau kev siv txuas ntxiv. Cov welds ua tiav nrog tooj liab electrodes feem ntau pom muaj lub zog zoo, kev ntseeg tau, thiab tsawg heev spatter.
Chromium Zirconium Copper (CuCrZr) Electrodes:
CuCrZr electrodes paub txog lawv cov hardness thiab tsis kam rau electrode sticking. Qhov sib ntxiv ntawm chromium thiab zirconium txhim kho cov electrode cov khoom nto, txo qhov nyiam ntawm cov hlau molten kom ua raws li electrode nto thaum vuam. Qhov no feature txo cov electrode contamination, ncua lub neej ntawm electrode, thiab txhim khu lub weld tsos. Welds ua nrog CuCrZr electrodes feem ntau nthuav tawm kev txhim kho nto tiav thiab txo cov electrode hnav.
Refractory Electrodes (piv txwv li, Tungsten Copper):
Refractory electrodes, xws li tungsten tooj liab, yog qhov zoo dua rau kev siv vuam uas muaj qhov kub siab lossis cov khoom nyuaj. Cov electrodes no muaj kev tiv thaiv kub zoo thiab ua haujlwm ntev, ua rau lawv tsim nyog rau cov txheej txheem vuam uas yuav tsum tau ua kom muaj cua sov ntev los yog koom nrog cov ntaub ntawv uas muaj cov ntsiab lus melting siab. Refractory electrodes tuaj yeem tiv taus qhov hnyav vuam thiab tswj kev ua haujlwm ruaj khov, ua rau cov welds txhim khu kev qha nrog tsawg electrode hnav.
Coated electrodes:
Coated electrodes yog tsim los muab kev ua haujlwm tshwj xeeb lossis daws qee qhov kev sib tw vuam. Piv txwv li, electrodes nrog cov coatings tshwj xeeb tuaj yeem muab kev tiv thaiv zoo dua rau kev ua kom zoo dua qub, txo qhov tawg, lossis txhim kho kev tiv thaiv kev hnav. Cov txheej txheem no tuaj yeem ua los ntawm cov ntaub ntawv xws li nyiaj, npib tsib xee, lossis lwm yam alloys, tsim kom tau raws li cov kev xav tau tshwj xeeb. Coated electrodes tuaj yeem pab ua kom zoo dua qub, txo qhov tsis xws luag, thiab txuas ntxiv electrode lifespan.
Composite electrodes:
Composite electrodes muab cov ntaub ntawv sib txawv los txhawb lawv tus kheej zoo. Piv txwv li, cov khoom siv hluav taws xob sib xyaw yuav muaj cov tub ntxhais tooj liab ncig los ntawm cov khoom siv refractory. Qhov kev tsim no sib txuas cov txiaj ntsig ntawm cov thermal conductivity siab los ntawm tooj liab thiab zoo heev thaum tshav kub kub los ntawm cov khoom refractory. Composite electrodes muab qhov sib npaug ntawm kev ua tau zoo thiab tus nqi-zoo, muab kev txhim khu kev ntseeg tau zoo hauv ntau daim ntawv thov.
Qhov kev xaiv ntawm electrodes nyob rau hauv nruab nrab zaus inverter qhov chaw vuam ho cuam tshuam qhov vuam tshwm sim. Copper electrodes feem ntau siv vim lawv cov thermal conductivity thiab hluav taws xob zoo heev. CuCrZr electrodes muab kev txhim kho hardness thiab txo electrode sticking. Refractory electrodes yog tsim rau kev siv kub-kub, thaum coated electrodes muab cov haujlwm tshwj xeeb. Composite electrodes muab cov khoom sib txawv kom ua tiav qhov sib npaug ntawm cov yam ntxwv ua haujlwm. Los ntawm kev xaiv qhov tsim nyog electrodes raws li cov kev xav tau tshwj xeeb vuam, cov tuam ntxhab tuaj yeem ua tiav qhov xav tau vuam zoo, kev ua haujlwm zoo, thiab kev ua haujlwm tag nrho hauv nruab nrab zaus inverter qhov chaw vuam ua haujlwm.
