Lub GB/T EZNiCu-1 (Z508) yog ib lub electrode vuam uas tsim tshwj xeeb rau kev kho thiab rov ua dua cov khoom siv hlau cam khwb cia. Nws qhov kev faib tawm raws li Suav Lub Tebchaws Standard GB/T qhia txog nws txoj kev ua raws li cov kev cai tshwj xeeb, ua kom muaj kev ua tau zoo thiab kev tswj xyuas zoo. Hom electrode no tau tsim los tso ib txheej ntawm cov hlau tshwj xeeb rau ntawm cov khoom siv hauv paus, ua rau nws tsis tseem ceeb rau kev saib xyuas thiab kho cov haujlwm thoob plaws ntau yam kev lag luam hnyav uas xav tau kev kho dua tshiab ntawm cov khoom siv hlau cam khwb cia.
Ib qho tshwj xeeb ntawm qhov noelectrode vuam ntoyog nws cov hlau tseem ceeb, uas yog tsim los ntawm cov hlau nickel-tooj liab, hu ua Monel. Cov khoom siv tseem ceeb no yog qhov tseem ceeb rau kev ua haujlwm ntawm electrode, vim nws tsim cov khoom siv vuam nrog kev ua haujlwm zoo heev thiab cov coefficient thermal expansion uas sib phim zoo li cov hlau cam khwb cia. Qhov kev sib raug zoo no yog qhov tseem ceeb rau kev txo qis kev ntxhov siab vuam thiab tiv thaiv kev tsim cov kab nrib pleb, uas yog cov teeb meem feem ntau cuam tshuam nrog kev vuam hlau cam khwb cia, yog li ua kom ntseeg tau tias kev kho kom zoo.
Qhov kev ua tau zoo ntawm lub electrode tau txhim kho ntxiv los ntawm nws cov txheej txheem graphitized flux. Cov txheej txheem no ua haujlwm ntau lub hom phiaj tseem ceeb thaum lub sijhawm vuam: nws muab kev ruaj khov ntawm arc, tsim cov pa roj tiv thaiv los tiv thaiv lub pas dej molten los ntawm kev ua qias tuaj hauv huab cua, thiab tsim lub hau slag los pab tswj kev khov ntawm cov hlau vuam. Cov neeg sawv cev graphitizing hauv cov txheej txheem txhawb nqa kev sib sau ua ke ntawm graphite hauv cov hlau vuam, uas txhim kho kev siv tshuab thiab pab ua tiav cov qauv hlau zoo ib yam li cov hlau cam khwb cia.
Lub tswv yim tseem ceeb rau qhov kev siv tshwj xeeb noelectrode vuam ntoyog kev kho qhov tsis zoo hauv cov hlau cam khwb cia grey thiab nodular. Nws yog qhov tshwj xeeb tshaj yog rau cov haujlwm xws li kev sau cov kab nrib pleb, kho cov yuam kev machining, thiab rov tsim cov chaw hnav uas xav tau kev machining tom qab-weld. Nws qhov kev ntseeg tau ua rau nws yog ib qho cuab yeej muaj txiaj ntsig hauv cov lag luam xws li kev tsim tsheb, kev tsim kho marine, thiab kev kho cov khoom siv hnyav, qhov twg nws pab txhawb rau kev ua haujlwm ntev ntawm cov khoom tseem ceeb.
GB/T EZNiCu-1 (Z508)electrode vuam ntoyog ib qho khoom siv thev naus laus zis siab heev uas tsim los daws cov teeb meem tshwj xeeb ntawm kev vuam hlau cam khwb cia. Kev sib xyaw ua ke ntawm nws lub Monel alloy core thiab graphitized flux coating muab kev daws teeb meem zoo rau kev ua tiav cov txheej txheem zoo, tshuab tau, thiab tawg-resistant surfacing. Rau cov kws tshaj lij koom nrog kev saib xyuas thiab kho cov hlau cam khwb cia, cov electrode no muab kev xaiv zoo thiab kev siv tshuab.
