Tsawg Alloy Steel Vuam Electrode
J557 SLA, J557SLB
GB/T E5515-G
AWS E8015-G
Nqe lus piav qhia: Qhov no yog qhov tsawg hydrogen sodium them tshwj xeeb electrode rau aluminized steel.Siv DCEP (cov khoom siv hluav taws xob ncaj qha tam sim no), thiab tuaj yeem txuas rau txhua txoj haujlwm nrog kev ua haujlwm luv luv.J557SLA tuaj yeem ncaj qha welded yam tsis tau tshem tawm cov txheej aluminized ntawm qhov zawj ua ntej vuam.Tab sis J557SLB yuav tsum tshem tawm cov txheej aluminized ntawm qhov zawj ua ntej vuam.
Daim ntawv thov: Nws yog siv rau vuam cov aluminized steel qauv nyob rau hauv lub corrosion nruab nrab ntawm hydrogen sulfide, sulfur, ammonia, ammonium bicarbonate thiab hydrogen nitrogen nrog ua hauj lwm kub hauv qab 540 ° C.Xws li cov kav dej boiler, cov khoom siv roj av refining, cov khoom siv chiv thiab cov kav dej, thiab lwm yam.
Tshuaj muaj pes tsawg leeg ntawm weld hlau (%):

Daim ntawv ceeb toom:
1. Cov electrode yuav tsum tau ci rau 1 teev ntawm ib ncig ntawm 350 ℃ ua ntej vuam ua haujlwm;
2. Nws yog ib qho tseem ceeb los ntxuav cov xeb, roj nplai, dej, thiab impurities ntawm vuam qhov chaw ua ntej vuam.
