E330 vuam electrode yog stainless hlau electrode siv rau shielded hlau arc vuam (SMAW), muaj nyob rau hauv qeb ntawm tshav kub{1}}resistant steel electrodes. Nws yog feem ntau siv rau vuam cam khwb cia lossis forged alloys nrog cov tshuaj zoo sib xws, thiab tshwj xeeb tshaj yog haum rau siab - qhov kub thiab txias.
Cov yam ntxwv tseem ceeb:
Tshuaj muaj pes tsawg leeg: E330 electrode yog siab -nickel chromium alloy electrode. Nws cov tshuaj muaj pes tsawg leeg muaj xws li:
Chromium (Cr): 14.0% - 17.0%
Nickel (Ni): 33.0% - 37.0%
Cov pa roj carbon (C): 0.18% - 0.25%
Manganese (Mn): 1.0% - 2.5%
Lwm cov khoom xws li molybdenum (Mo), silicon (Si), phosphorus (P), sulfur (S), thiab tooj liab (Cu) kuj muaj cov kev txwv sib xws.
Kev ua haujlwm thiab kev siv:
Kev Ua Haujlwm Kub Kub Kub: Cov hlau tso ntawm cov electrode no muaj cua sov zoo thiab oxidation tsis kam, nrog rau qhov kub siab tshaj plaws ntawm kev ua haujlwm ntawm kwv yees li 980℃(1800℃F).
Cov ntawv thov tseem ceeb: Feem ntau siv rau vuam HK-40 (ie, 25Cr-}20Ni) hom cua sov-cov khoom siv cam khwb cia hlau, xws li cov kav hlau tawg, cov kav hlau kub kub, thiab lwm yam khoom uas yuav tsum tau ua haujlwm ntev ntawm qhov kub thiab txias hauv kev lag luam petrochemical.
Weldability: Ua tib zoo tswj cov khoom cua sov yog tsim nyog thaum lub sij hawm vuam kom txo tau qhov kev pheej hmoo ntawm microcracking. Nyob ntawm seb lub workpiece thickness thiab kev tuav pov hwm, tsim nyog preheating thiab interpass kub tswj yuav tsum tau.
Qauv thiab Qauv:
E330 yog tus qauv electrode hauv AWS (American Welding Society) A5.4 tus qauv.
Cov txheej txheem txheej txheem muaj xws li -16 (xws li, E330-16), qhia txog alkaline lossis titania-calcium txheej txheej, haum rau AC lossis DC rov qab polarity (DC+).
Cov ntsiab lus
Hauv luv luv, E330 vuam electrodes yog phau ntawv vuam electrodes tshwj xeeb tsim los rau vuam siab -nickel chromium tshav kub- resistant alloys (xws li HK-40). Lawv cov txiaj ntsig tseem ceeb nyob hauv lawv lub zog thiab oxidation tsis kam ntawm qhov kub thiab txias, ua rau lawv cov khoom siv vuam tseem ceeb hauv kev tsim khoom thiab kev saib xyuas cov khoom siv kub kub hauv kev lag luam xws li petrochemicals thiab metallurgy.
