APPLICATIONS:
Nws yog tsim rau vuam ntawm high-strength grey hlau thiab nodular cam khwb cia hlau, xws li lub tog raj kheej, cav thaiv, iav kem, thiab lwm yam ..
CLASSIFICATIONS:
AWS A5.15 / ASME SFA5.15 ENiFe-CI
JIS Z3252 DFCNiFe
CHARACTERISTIS:
AWS ENiFe-CI (Z408) yog cov cam khwb cia hlau electrode nrog nickel hlau alloy core thiab muaj zog txo cov graphite txheej.Nws tuaj yeem siv rau hauv AC thiab DC dual lub hom phiaj, muaj qhov ruaj khov arc, thiab yooj yim rau kev khiav lag luam.Cov electrode muaj cov yam ntxwv ntawm lub zog siab, zoo plasticity, qis linear expansion coefficient thiab lwm yam.Qhov tawg tsis kam rau grey cam khwb cia hlau yog ntau npaum li ntawd rau Z308, thaum lub tawg tsis kam rau nodular cam khwb cia hlau yog ntau tshaj ENi-CI (Z308).Rau cam khwb cia hlau nrog ntau dua phosphorus (0.2% P), nws kuj muaj cov txiaj ntsig zoo thiab nws cov kev ua haujlwm txiav qis dua Z308 thiab Z508 me ntsis.Z408 yog siv nyob rau hauv vuam ntawm grey hlau thiab nodular cam khwb cia hlau rau chav tsev
CEEB TOOM:
Ua ntej vuam, cov electrodes yuav tsum tau ci rau 1 teev nrog qhov kub ntawm 150 ± 10 ℃ ua ntej siv.
Thaum vuam, nws yog tsim nyog los nqa nqaim weld thiab txhua qhov ntev vuam yuav tsum tsis pub tshaj 50 hli.Rauj qhov chaw vuam maj mam nrog rauj tam sim ntawd tom qab vuam txhawm rau txhawm rau tshem tawm kev ntxhov siab thiab tiv thaiv kev tawg.
Kev siv hluav taws xob qis yog pom zoo.
